Peningkatan Performa Induk dan Uji Penggunaan Ekstrak Daun Teh (Camelia Sinensis) Terhadap Keberhasilan Penetasan Telur Ikan Semah (Tor Duoronensis)
type: item
description: Semah fish (Tor douronensis) is one of the endemic fish species with high economic value. However, the hatch rate of Semah fish eggs is still low due to contamination from waste and fungi. Washing the eggs with natural materials has been used to improve hatching success in various fish species, and one of the natural materials used is tea leaves because they contain tannins and flavonoids that can inhibit bacterial and fungal attacks. The purpose of this study is to determine the effectiveness of using tea leaf extract (Camelia sinensis) on the hatching success of Semah fish eggs (Tor douronensis) at an optimal dosage. This study will use a completely randomized design (CRD) with 4 treatments and 3 replications, namely: Treatment A) Tea leaf extract concentration 0.4 ml/L, Treatment B) Tea leaf extract concentration 0.6 ml/L, Treatment C) Tea leaf extract concentration 0.8 ml/L, and Treatment D) Tea leaf extract concentration 0 ml/L (Control). The research results, which have been conducted and analyzed descriptively regarding the injection of hCG three times over a 30-day maintenance period, show an effect on the gonad maturity index with an average value of 6.70%. The egg hatchability is 0.8 ml/L with a success rate of 89.67%, and it results in the largest egg diameter distribution ranging from 1.8 to 2.4 mm.

Respon Ikan Lele Dumbo (Clarias gariepinus B) Terhadap Pakan Tepung Ikan, Tepung Maggot dan Tepung Media Maggot BSF Difermentasi IRS
type: item
description: The food consumed is part of the body's active biochemical elements that are essential for fish growth. Therefore, various considerations are needed to provide fish with quality feed that meets their needs. Feed quality can be assessed by its protein content, which can be obtained from high-protein plant materials and the assistance of bacterial decomposers, as well as from the bioconversion of BSF maggots. This study aimed to analyze the effect of cattle rumen contents (IRS) on cassava leaf flour (Manihot utilissima), tarum leaf flour (Indigofera zollingeriana), and lamtoro leaf flour (Leucaena leucocepphala) to produce maggots. Maggot flour and the organic media from one 21-day cycle of BSF (Black Soldier Fly) flies were made into pellets supplemented with fish meal (TI) for African catfish (Clarias gariepinus B). A completely randomized design with 4 treatments and 3 replications was used, with treatment A (IRS 0.00%); B (IRS 5.0% : C (IRS 10.0%), D (IRS 15.0%). The observation results in the form of the average proximate protein of the best final organic maggot media raw materials in C and D were 30.75%; and 31.55%, respectively, the initial organic media protein was 20.00% and 20.15%. The best proximate pellet feed was also in C and D with 36.53% and 37.55% protein and 307.34 and 285.73 Kcal/100 grams of feed. The best maggot biomass in D (60.59 grams) followed by C (42.60 grams) with an ESE conversion value (organic substrate efficiency) in treatments A (5.49%), B (4.91%), C (7.10%) and D (10.10%). For the best average individual maggot weight in treatment A (0.26 grams/tail), followed by B (0.22 grams), the lowest D (0.18 grams/tail) and the best individual maggot length in treatment A (1.55 cm), followed by B (1.15 cm) and the lowest C (0.93 cm). The best individual maggot counts were C (1107 tails/600 grams) and D (969 tails/600 grams), followed by B (530 tails/600 grams) and A (526 tails/600 grams). The best absolute growth of catfish was the average indiv…

Performa Pertumbuhan dan Kelangsungan Hidup Udang Vaname (Litopenaeus vannamei) dengan Padat Tebar 114 ekor/m² di Tefa Politeknik KP, Kupang
type: item
description: This study analyzes the growth and survival performance of whiteleg shrimp (Litopenaeus vannamei) reared at a stocking density of 114 shrimp/m² during a 90-day period at the Teaching Factory of Poltek KP Kupang. Cultivation was conducted in a 350 m² pond using a combination of blind feeding and biomass-based feeding methods, with routine monitoring of water quality parameters including temperature, salinity, pH, dissolved oxygen, and water clarity. The average body weight (ABW) increased significantly from 2.59 g/shrimp at day 30 to 21.74 g/shrimp at day 90. The average daily gain (ADG) during the culture fluctuated between 0.13 and 0.42 g/shrimp/day, indicating good growth performance. Feed conversion ratio (FCR) was 1.18, indicating efficient feed utilization, while the survival rate (SR) reached 85.1%, reflecting effective management and favorable culture conditions. Water quality parameters remained within optimal national standards, supporting shrimp physiological processes. The findings suggest that whiteleg shrimp aquaculture at this stocking density yields good growth and high survival, offering practical insights to improve intensive vannamei shrimp farming, particularly in the Nusa Tenggara Timur region.

Perbandingan Teknik Budidaya Rumput Laut (Gracilaria verrucosa) dengan Metode Longline dan Broadcast di PT. Rejeki Bintang Samudra, Sidoarjo, Jawa Timur
type: item
description: Indonesia remains one of the world's largest seaweed exporters; however, the optimisation of added value through the downstreaming of Gracilaria verrucosa still faces challenges regarding cultivation efficiency. This research aims to analyse the comparative cultivation techniques of the broadcast and longline methods, as well as the potential of polyculture systems at PT Rejeki Bintang Samudra. The parameters tested included biomass, Specific Growth Rate (SGR), and harvest productivity.The results indicated that both methods delivered superior performance, with biomass reaching 9,550 grams and an SGR of 3.13% at DOC 50. Productivity analysis based on harvest yields showed significant fluctuations at each sampling point, with a total accumulated weight of 118,740 kg from a total of 150 sacks. The highest productivity was recorded at the 40th sampling at 810.62 kg/sack, whilst the average total productivity stood at 791.6 kg/sack. Although both methods demonstrated excellent results, the reliance on monoculture systems remains a constraint for scalability. Consequently, the integration of Gracilaria verrucosa into a polyculture system with milkfish is recommended as a strategy for an aquaculture transformation that is more adaptive, sustainable, and of higher economic value.

Pengaruh Penambahan Asam Amino Triptofan Pada Pakan Buatan Terhadap Kelangsungan Hidup dan Pertumbuhan Ikan Kapiat (Barbonymus schwanenfeldii)
type: item
description: This study aims to analyze the effect of artificial feed with different doses of tryptophan amino acid supplementation and determine the appropriate dose of tryptophan amino acid supplementation on the survival and growth rate of tinfoil barb (B. schwanenfeldii). This study used a Completely Randomized Design (CRD) with 4 treatments and 3 replications : P1 (0% tryptophan), P2 (1% tryptophan), P3 (2% tryptophan), and P4 (3% tryptophan). The results showed that the supplementation of tryptophan amino acid to artificial feed did not significantly affect survival and growth, as well as feed utilization efficiency and feed conversion ratio. The supplementation of tryptophan amino acid to artificial feed resulted in 100% survival rate in all treatments. The highest growth rate in total length was achieved in treatment P2 (1%), the highest growth rate in absolute weight was achieved in treatment P2 (1%), and the highest growth rate was achieved in treatment P2 (1%). the highest result for feed efficiency was obtained in treatment P2 (1%), and the lowest result for food conversion rasio was obtained in treatment P2 (1%). The lowest results for total length growth, absolute weight growth, growth rate, and feed efficiency were obtained in treatment P4 (3%), while the highest food conversion rasio was obtained in treatment P4 (3%). Water quality parameters during the rearing period were still considered suitable to support the survival and growth of tinfoil fish (B. schwanenfeldii).

Pengaruh Pakan Egg Custard terhadap Laju Pertumbuhan Benih Ikan Lele Lokal (Clarias batrachus)
type: item
description: Catfish (Clarias batrachus) is an important aquaculture commodity in Indonesia due to its rapid growth and high market demand. Feed plays a crucial role in determining the growth and survival of fry; therefore, alternative feeds that are nutritious and cost-effective, such as egg custard, are needed. This study aimed to evaluate the effects of egg custard and Artemia feed on the growth performance and survival rate of catfish fry. The experiment consisted of two treatments, namely egg custard and Artemia. Parameters observed included daily growth rate, absolute weight gain, feed conversion ratio (FCR), and survival rate (SR). Data were analyzed descriptively and supported by statistical analysis. The results showed that egg custard resulted in higher daily growth rate and absolute weight gain, as well as better survival rate compared to Artemia. However, the FCR value of egg custard was higher, indicating lower feed efficiency. Therefore, egg custard has potential as an alternative feed to enhance growth and survival of catfish fry, but further optimization is required to improve feed efficiency

Pengaruh Pakan Egg Custard terhadap Laju Pertumbuhan Benih Ikan Mas (Cyprinus carpio)
type: item
description: This study aimed to determine the effect of egg custard feed on the growth of common carp (Cyprinus carpio) fry. The experiment was conducted at the Integrated Laboratory of Universitas Tidar, Magelang City, Central Java, in July to August 2025 using a qualitative approach with data collected through experimental testing. Observed parameters included Survival Rate (SR), Absolute Weight Growth (Wm), Specific Growth Rate (SGR), and Feed Conversion Ratio (FCR). The results showed that egg custard feed provided better growth performance and survival compared to Artemia. The egg custard treatment achieved an SR of 100%, absolute weight growth of 10.1 g, SGR of 40.4%, and FCR of 7.92. In contrast, the Artemia treatment produced an SR of 60%, absolute weight growth of 3.1 g, SGR of 12.4%, and FCR of 15.69. These findings indicate that egg custard feed is more effective than Artemia in improving the growth and survival of common carp fry during the nursery phase. This formulated feed can serve as an alternative for common carp (Cyprinus carpio) culture and can potentially be applied to other cultured fish and shrimp species.

Analisis Faktor Determinan Budidaya Pen Culture Ikan Napoleon (Cheilinus undulatus) Dalam Potensi Pengembangan Kabupaten Natuna
type: item
description: This study investigates the influence of stocking density, seed quality, environmental conditions, and technology on production performance, with management serving as a mediating variable in aquaculture enterprises. A quantitative research design was applied using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method. Evaluation of the measurement model demonstrated that all constructs satisfied validity and reliability requirements. Outer loading values exceeded 0.70, Average Variance Extracted (AVE) ranged from 0.603 to 0.770, and Composite Reliability values were between 0.881 and 0.944. Discriminant validity was confirmed using both the Fornell–Larcker criterion and the Heterotrait–Monotrait (HTMT) ratio, with all values below 0.90. The structural model analysis showed that the proposed model explained 49.4% of the variance in production performance (R² = 0.494) and 7.3% of the variance in management (R² = 0.073). Hypothesis testing revealed that management had a strong and significant positive effect on production performance (β = 0.681; t = 12.720; p < 0.001), supported by a large effect size (f² = 0.850). Conversely, stocking density, seed quality, and environmental factors did not exhibit significant direct effects on either management or production. Technology showed no direct impact on production; however, it positively influenced management and demonstrated a marginally significant indirect effect on production through management.

Produksi Ikan Nila (Oreochromis niloticus) Strain Politeknik Negeri Lampung (PoliNILA) dengan Metode Selective Cross Breeding
type: item
description: Tilapia cultivation in Lampung Province still faces many challenges, including the limited availability of tilapia seeds. This is due to the low availability of tilapia broodstock with superior specifications. This poses a challenge for the Lampung State Polytechnic to produce new strains of tilapia broodstock with distinctive advantages, thereby boosting seed production and consumption of tilapia in Lampung Province. One effort that can be made to create new strains of superior tilapia is by using selective cross-breeding between two superior tilapia species, namely the Srikandi tilapia and the Larasati tilapia. Both types of tilapia have their own unique superior characteristics, so it is hoped that this will be able to create new strains of tilapia that combine the advantages of both. The two superior Nile tilapia broodstock will be cross-bred with the composition in Treatment A, namely male Nile tilapia broodstock Srikandi with female Nile tilapia broodstock Larasati and Treatment B, namely female Nile tilapia broodstock Srikandi with male Nile tilapia broodstock Larasati with each treatment having two replications. This research will be conducted for 90 days of maintenance which includes the process of adaptation of broodstock to the environment, the spawning process and the process of maintaining larvae and seeds. The parameters tested include the number of eggs produced (fecundity), egg hatching rate, survival rate of larvae and fish seeds (survival rate), absolute weight and length gain. The observations during the spawning phase showed that treatment B was the best treatment, measured by the number of larvae produced, which was 1,600 larvae, with a survival rate (SR) of 63% during 28 days of maintenance. Data on the growth of tilapia larvae during 28 days of maintenance showed that the control treatment had superior weight growth performance compared to the other two treatments, namely 6 g with a length of 6.4 cm.

Potensi Chlorella sp. Isolat Air Gambut Terhadap Optimasi Pertumbuhan dan Kelangsungan Hidup Benih Ikan Betok (Anabas testudineus)
type: item
description: This study aims to evaluate the potential of peat water microalgae Chlorella sp. on the survival and growth of Betok fish (Anabas testudineus) fingerlings. An experimental method was employed using a Completely Randomized Design (CRD) consisting of three dosage treatments (A: 10 mL, B: 20 mL, C: 30 mL) with three replications. Parameters observed included Survival Rate (SR), absolute weight growth, absolute length growth, and Specific Growth Rate (SGR) over a 42-day rearing period. The results indicated that the administration of peat water microalgae had no significant effect ($P > 0.05$) on any of the tested parameters. However, visually, treatment C (30 mL) showed the highest results with a survival rate of 87.0%, absolute weight growth of 0.64 g, absolute length growth of 1.00 cm, and SGR of 1.13%. This suggests that nutrient intake from microalgae at the fingerling stage is predominantly used for maintaining physiological functions and suppressing environmental stress rather than somatic growth. Water quality parameters during the study remained within the optimal range, with temperatures of 26.0–27.5°C, pH 5.42–6.91, and DO 5.4–6.9 mg/L.

Efektivitas Ekstrak Akar Kaik-Kaik (Uncaria cordata) Sebagai Feed Additive Terhadap Efisiensi Pemanfaatan Pakan dan Pertumbuhan Ikan Nila (Oreochromis niloticus)
type: item
description: High feed costs (accounting for 60–70% of production costs) and the risks of stress in intensive aquaculture necessitate the use of safe, natural feed additives. Kaik-kaik root (Uncaria cordata) contains bioactive compounds such as alkaloids and flavonoids, which have the potential to enhance fish health and metabolic efficiency. This study aimed to analyze the effectiveness of adding Uncaria cordata root extract as a feed additive on feed utilization efficiency, growth performance, and survival rate of Oreochromis niloticus. The experiment was conducted using a Completely Randomized Design (CRD) with four treatments and three replications, namely P0 (0% as control), P1 (2%), P2 (4%), and P3 (6%) inclusion levels of the extract in the feed. The observed parameters included growth performance (weight gain and specific growth rate/SGR), feed utilization efficiency (feed conversion ratio/FCR and feed efficiency), and survival rate (SR). The results showed that the addition of the extract had a significant effect (P<0.05) on growth performance and feed utilization efficiency, but no significant effect on survival rate. The best performance was observed in treatment P2 (4%), with an SGR of 3.62%/day, FCR of 1.48, and feed efficiency of 67.6%. Meanwhile, the highest survival rate was also recorded in P2 at 93%. The improvement in performance is presumably related to the presence of bioactive compounds that enhance metabolic efficiency and fish health. However, a decline in performance was observed at the highest dose (6%), indicating potential negative effects at excessive levels.In conclusion, Uncaria cordata root extract has potential as a natural feed additive to improve the aquaculture performance of Oreochromis niloticus, with an optimal inclusion level of 4%.

type: item
description: Commercial feed usually accounts for 60-70% of the total production costs in aquaculture. Therefore, feed additives are needed to support fish growth and feed efficiency to reduce production costs. This study aims to determine the effect of adding a synbiotic mixture to the feed of Sangkuriang catfish (Clarias gariepinus). This research utilized a Completely Randomized Design (CRD) consisting of 4 treatments with 4 replications, resulting in 16 experimental units. The best average absolute weight and absolute length growth of Sangkuriang catfish fingerlings were found in treatment P4 with a 25% synbiotic mixture. Observations on fish survival rates showed the best results with the inclusion of the synbiotic mixture in the feed.The highest feed efficiency was obtained in treatments P4 and P3, with an average of 0.80%, meaning that 80% of the feed was effectively utilized for daily needs. This was followed by treatment P2 at 0.78%, while the lowest efficiency was found in treatment P1 at 0.77%. The results indicated that all treatments were significantly different. Analysis showed that the lowest Feed Conversion Ratio (FCR) was obtained in P4 (25% synbiotic) and P3 (20% synbiotic), both showing an average value of 1.25%. P2 (15% synbiotic) followed with 1.29%, and P1 (10% synbiotic) with 1.30%, which remains within the standard threshold. Water quality parameters monitored during the study included temperature, pH, and dissolved oxygen

Pengaruh Kepadatan Berbeda Terhadap Kinerja Produksi dan Kualitas Air Ikan Patin (Pangasius Hypophthalmus) Pada Media Bersalinitas 4 ppt
type: item
description: The use of isoosmotic media has been recommended as one of the efforts to reduce stress in fish kept in high stocking densities. Increases in stocking density should consider carrying capacity and water quality. One of the water quality parameters that can support the survival of catfish is maintenance in an isoosmotic condition with a salinity of 4 ppt. This study aims to analyze the effects of different densities on production performance, water quality, and physiological responses of Siamese catfish (Pangasius hypophthalmus) in media with a salinity of 4 ppt. The research was conducted using a completely randomized design with four density treatments (5 fish L-1, 8 fish L-1, 11 fish L-1, and 14 fish L-1) and three replications for each treatment. The results show that salinity of 4 ppt can support the life of catfish up to high densities with the best production performance at a stocking density of 14 fish L-1.

Penggunaan Feed additive herbal pakan dengan dosis berbeda terhadap kinerja budidaya dan vitalitas Ikan Lele Sangkuriang (Clarias gariepinus) di PT. Imadudin Center Bima
type: item
description: Catfish is one of the most popular species for aquaculture because of its strong market demand, adequate nutritional value, and relatively simple cultivation technology. Catfish is also a species that experiences a significant increase in production demand each year. In 2022, the Ministry of Marine Affairs and Fisheries (KKP) released data showing that catfish production in Indonesia reached 1.06 million tons, with a value of IDR 18.93 trillion in 2021. The increasing demand for catfish is directly proportional to the excessive use of feed in catfish farming. Overfeeding can lead to feed accumulation at the bottom of the water, resulting in decreased water quality. Poor water quality negatively affects catfish by reducing their immunity, making them more susceptible to stress, and slowing their growth. One way to improve growth and immunity in fish is by adding feed additives to their diet. Herbal feed additives offer several advantages: they are affordable, easy to obtain, environmentally friendly, enhance fish immunity, and improve feed digestibility. This study aimed to evaluate the performance and vitality of catfish given herbal feed additives at different dosages. The experiment consisted of three treatments with three replications: K (control), A (dose of 5 ml/kg feed), and B (dose of 10 ml/kg feed). The results showed that the addition of herbal feed additives at different dosages did not significantly affect survival rate, Feed Conversion Ratio (FCR), Average Daily Growth (ADG), or resistance to formalin. However, it did have a significant effect on Mean Body Weight, absolute length, and resistance to salinity. The best results were obtained in treatment B (10 ml/kg feed), which produced a Mean Body Weight (MBW) of 53.6 g, an Average Daily Growth (ADG) of 1.64 g/day, a Feed Conversion Ratio (FCR) of 1.0, an absolute length of 11.6 cm, an absolute weight gain of 103.4 g, a 100% survival rate in the formalin test, and a salinity resistance time of 179.2 minut…

Identifikasi Kandungan Nutrisi Limbah Pertanian Dan Perkebunan Di Provinsi Jambi Sebagai Sumber Bahan Baku Pakan Alternatif
type: item
description: Feed is the largest component of operational costs in cultivation activities, reaching 60-70% of total production costs. However, the current price of feed is still very high due to feed raw materials still being imported. Therefore, efforts are needed to reduce import values by substituting soybean meal with other alternative raw materials. Alternative raw materials can be obtained, one of which is from the utilization of agricultural and plantation waste. This study aims to identify and analyze the nutritional content of agricultural and plantation waste in Jambi Province as a source of alternative fish feed raw materials. This study will be conducted over 6 months in several locations that produce agricultural and plantation waste in Jambi Province. The determination of research areas is done purposively considering that the research locations are sources of agricultural and plantation waste in Jambi Province. Types of agricultural and plantation waste that will be identified covering corn, pineapple, oil palm, rubber, coconut, areca nut, and sugarcane waste. Data collected include the total production of agricultural and plantation products over the past year, estimates of waste from production, identification of potential agricultural and plantation waste based on availability, and analysis of nutrient content (proximate). The research results show the nutrient values of each agricultural and plantation waste covering (protein, fat, fiber, moisture content, ash, and dry matter). Rubber seed waste shows the highest protein and fat values, namely 28.9% and 24.13%. The highest fiber content is found in areca nut husk at 46.45%. The highest moisture and ash content are found in pineapple peel at 77.52% and 4.6%. Meanwhile, the highest dry matter value is found in oil palm at 90.5%.

Effect of palm kernel meal level on feed intake, body composition, and hepatic histopathology features of Kelabau (Osteochilus melanopleurus)
type: item
description: The effect of including palm kernel meal (PKM) on the feed intake, body composition, and hepatic histopathology of Kelabau (Osteochilus melanopleurus) was experimentally studied in a 50-day feeding trial. Four experimental diets were formulated in dry pellet form with a protein content of approximately 30%. The treatments consisted of varying PKM concentrations (0%, 5%, 15%, and 20%). The experimental fish were reared in 12 aquaria (30 x 30 x 40 cm³) and fed to satiation three times daily. A Completely Randomized Design (CRD) was employed for this research. Results indicated that the treatments had no significant effect (P > 0.05) on total feed intake. However, feed consumption tended to decrease as PKM content increased. Furthermore, PKM inclusion significantly influenced body composition; higher PKM levels led to a sharp increase in Nitrogen-Free Extract (NFE), while simultaneously reducing body protein and lipid content. Additionally, increased PKM levels were observed to cause hepatic lipid accumulation and the displacement of cell nuclei to the periphery.

Substitusi Tepung Ikan Dengan Tepung Cacing Tanah (Lumbricus rubellus) Terhadap Retensi Protein, dan Retensi Lemak, Pada Ikan Mas (Cyprinus carpio)
type: item
description: This study aims to analyze protein retention and fat retention in common carp (Cyprinus carpio) fed formulated feed with substitutions of fishmeal and earthworm meal (L. rubellus), as well as to determine the best substitution ratio between fishmeal and earthworm meal (L. rubellus) in formulated feed for protein retention and fat retention in common carp (Cyprinus carpio). The study used a completely randomized design (CRD) consisting of four treatments and three replications. The treatments in this study were differences in the doses of fishmeal and earthworm meal given to the carp at different doses, namely PA (100% fishmeal and 0% earthworm meal), PB (75% fishmeal and 25% earthworm meal), PC (50% fishmeal and 50% earthworm meal), and PD (25% fishmeal and 75% earthworm meal). The main parameters observed included protein retention, fat retention, and absolute biomass weight growth, while supporting parameters such as water quality were measured periodically. The results showed that substituting fishmeal with earthworm meal had a significant effect (P<0.05) on protein retention, fat retention, and absolute weight growth of the carp. Treatment C (50% fishmeal + 50% earthworm meal) gave the best results with protein retention of 86%, fat retention of 168.1%, and absolute weight growth of 57.6 g. This indicates that the combination of fishmeal protein and earthworm meal at a 50% substitution level can provide optimal nutritional balance, particularly in amino acid profile, thereby improving metabolic efficiency and nutrient utilization by the fish. Water quality parameters during the study remained within the optimal range for carp survival, and thus did not affect the study results.

Analisis Kualitas Air Danau Mas Harun Bastari di Kabupaten Rejang Lebong Provinsi Bengkulu, Indonesia
type: item
description: Lake Mas Harun Bastari is one of the important tourism lakes in Bengkulu Province with strategic ecological and economic functions. Increasing tourism and agricultural activities around the lake have the potential to affect water quality through the input of organic matter and nutrients. This study aimed to analyze the water quality status of Lake Mas Harun Bastari based on physical and chemical water parameters, as well as to identify indications of eutrophication and potential pollution sources. The study was conducted from January to February 2026 at six observation stations distributed across the northern, southern, eastern, and western parts of the lake. Sampling points were determined using a purposive sampling method based on environmental characteristics and anthropogenic activities surrounding the waters, such as tourism areas, agricultural land, and water inlet and outlet zones. Water sampling was carried out using the grab sampling method in accordance with SNI 6989.57:2008 concerning surface water sampling methods. The parameters analyzed included temperature, Total Dissolved Solids (TDS), pH, Dissolved Oxygen (DO), phosphate (PO₄-P), ammonia (NH₃), Chemical Oxygen Demand (COD), and nitrate (NO₃⁻). Data were analyzed descriptively and compared with the Class II water quality standards based on Government Regulation No. 22 of 2021. The results showed that water temperature ranged from 26.3–26.8°C, TDS 20–58 mg/L, pH 6.39–6.85, DO 5.7–6.4 mg/L, phosphate <0.080 mg/L, ammonia 0.015–0.32 mg/L, COD <5.086–31.951 mg/L, and nitrate 1.216–4.924 mg/L. Most parameters still met the Class II water quality standards, except for COD values at stations 3, which exceeded the permissible threshold. Low phosphorus concentrations and high DO levels indicated that the waters were still in good condition and had not experienced severe eutrophication. However, elevated COD levels at several locations indicated the presence of organic matter inputs that require attention. In …
