Abstract

Community Service Activities entitled Freshwater Lobster and Silkworm Cultivation, were carried out from September to November 2024. The need for freshwater lobster feed that is difficult to obtain makes natural feed such as silkworm cultivation, an alternative to be used as feed for freshwater lobster cultivation. In addition, Freshwater Lobster cultivation is still very rarely carried out in the Gorontalo area, thus providing opportunities and benefits for inmates to be able to become independent after leaving prison. The need for freshwater lobster feed that is difficult to obtain makes natural feed for larvae/fry such as silkworms, an alternative to be used as feed for freshwater lobster cultivation. This PKM activity is a new hope for inmates to get a sustainable livelihood and income.

Abstract

The high cost and difficulty in meeting the nutritional requirements of feed presentfundamental challenges in the cultivation of humpback grouper (Cromileptes altivelis).Supplementary feed in the form of anchovies (Stolephorus sp) is an alternative source of nutrientsto support growth and survival. This study aims to evaluate how anchovy supplementation affectsthe growth rate, survival rate, and feed efficiency in the rearing of juvenile humpback grouper.The study utilized a Completely Randomized Design (CRD) with four treatments, each replicatedthree times. Data obtained from observations were analyzed using ANOVA and the LeastSignificant Difference (LSD) test to identify treatments that showed significant differences.Treatment C yielded the highest daily growth rate at 5.75% and the best absolute length gain of4.03 cm. Treatments B and C showed the highest survival rates, reaching 93.33%, and thehighest feed efficiency, with a value of 0.224. During the research, water temperature ranged from28.17°C to 31.09°C, pH levels were between 7.02 and 8, and salinity ranged from 31.11 to 34.92ppt. The results indicate that adding anchovy feed significantly improves juvenile humpbackgrouper growth and feed efficiency, but does not significantly affect their survival rate.

Abstract

The rearing of Mojosari ducks in Indonesia has become increasingly important as an alternative source of animal protein. However, the high cholesterol content in duck meat presents a challenge to its consumption. This study aims to evaluate the effect of turmeric supplementation in feed on cholesterol levels in the liver, blood, and meat of Mojosari ducks, as well as the organoleptic quality of the resulting meat. The experiment utilized a factorial Randomized Completely Block Design (RCBD), where ducks were divided into four treatment groups based on turmeric dosage: 0%, 6%, 8%, and 10%. Parameters measured included cholesterol levels in the liver, blood, and meat, as well as organoleptic assessments of taste, aroma, texture, color, and tenderness of the meat. The results indicated that turmeric supplementation significantly reduced cholesterol levels in the liver, blood, and meat of the ducks, with the 8% and 10% turmeric groups showing the lowest cholesterol levels. Turmeric supplementation also improved the tenderness and color quality of the duck meat, although no significant differences were observed in taste and aroma. The reduction in cholesterol levels suggests the potential of turmeric as an effective feed additive for producing healthier duck meat that is more appealing to consumers. These findings have implications for the development of feed based on natural ingredients that can enhance duck meat quality and support the sustainability of the duck farming industry in Indonesia.

Abstract

Small pelagic fisheries play an important role in food security, coastal livelihoods, and local fishery economies in Indonesia. Sardinella fimbriata is one of the economically important small pelagic fish species widely utilized in coastal communities. However, increasing fishing pressure may alter population size structure and reduce reproductive sustainability. This study aimed to analyze the size structure, gonad maturity stage, and exploitation status of Sardinella fimbriata in Kwandang Waters, Tomini Bay, Indonesia. The research was conducted from August to November 2025 using a descriptive quantitative approach. A total of 1,560 fish samples collected from commercial landings were measured for total length and examined macroscopically for gonad maturity. Data were analyzed using length-frequency distribution, maturity proportion, and logistic regression to estimate length at first maturity (L₅₀). The results showed that fish length ranged from 8.0 to 19.9 cm and was dominated by the 12.0–15.9 cm size group, accounting for 75.45% of total samples. Immature gonads dominated the catch, representing 91.35% of individuals, while mature fish accounted for only 8.65%. Logistic regression estimated L₅₀ at 16.72 cm, whereas the average catch length was 13.56 cm with an Lc/L₅₀ ratio of 0.81. These findings indicate that most fish were captured before reaching reproductive maturity, suggesting growth overfishing conditions. The study highlights the importance of minimum catch size regulation, selective fishing gear, and routine biological monitoring to support sustainable management of small pelagic fisheries in Tomini Bay.

Abstract

Food safety of fresh fish is an important concern because fish is highly perishable and may be misused with hazardous preservatives such as formalin. This study aimed to determine formalin content and analyze the relationship between length and weight of Nile tilapia (Oreochromis niloticus) and formalin levels in traditional markets of Gorontalo City. The study was conducted from January to February 2026 in five traditional markets, namely TPI Tenda, Moodu, Potanga, Andalas, and Sentral. Nile tilapia samples were analyzed using a formaldehyde test kit, and formalin levels were expressed in ppm. Total length and fish weight were measured, and the relationship between physical size and formalin content was analyzed using Pearson correlation. The results showed that all Nile tilapia samples tested positive for formalin, with concentrations ranging from 0.11 to 0.23 ppm. The highest formalin levels were found in TPI Tenda and Moodu, each at 0.23 ppm, while the lowest level was found in Sentral at 0.11 ppm. Fish length ranged from 19.43 to 25.61 cm, while fish weight ranged from 0.17 to 1.78 g. The correlations between length and formalin content and between weight and formalin content were both very strongly negative, with r = -0.97. These findings indicate that smaller fish tended to contain higher formalin levels. Market supervision, trader education, and formalin-free fish handling practices should be strengthened to protect consumer health.

Abstract

Nile tilapia (Oreochromis niloticus) culture requires an efficient and low-cost feeding strategy that can support fry growth and survival. This study aimed to analyze the effects of three types of natural feed, namely silk worms, earthworms, and snails, on absolute length growth, absolute weight growth, and survival of Nile tilapia fry. The study was conducted at the Aquaculture Laboratory, Faculty of Science and Computer Science, Universitas Muhammadiyah Gorontalo, from January 31 to March 2, 2026. An experimental method was applied using a Completely Randomized Design consisting of three treatments and three replications. A total of 45 Nile tilapia fry were reared in 9 plastic containers filled with 10 L of water, with 5 fish in each container. Growth and survival data were analyzed using ANOVA at the 5% significance level, while water quality was analyzed descriptively. The results showed that the type of natural feed had no significant effect on absolute length growth, absolute weight growth, and survival. Descriptively, silk worms produced the highest length and weight growth, with values of 2.99 cm and 6.37 g, respectively. Snails produced the highest survival rate of 86.66%. Water quality remained stable, with temperature ranging from 26.3 to 26.8°C, pH from 7.6 to 7.9, and dissolved oxygen from 5.2 to 5.6 mg/L. These findings indicate that silk worms are potential natural feed for improving growth, while snails support the survival of Nile tilapia fry.

Abstract

High feed costs remain a major constraint in Nile tilapia (Oreochromis niloticus) aquaculture, requiring alternative feed formulations based on local ingredients with adequate nutritional quality. This study aimed to evaluate the proximate composition of fish feed formulated from snail meal, Azolla meal, and turmeric as a phytobiotic supplement. The study used an experimental method with a Completely Randomized Design consisting of three treatments and three replications. The feed formulations were P1, consisting of 55% snail meal, 25% Azolla meal, 5% turmeric, 10% corn flour, and 5% tapioca flour; P2, consisting of 39% snail meal, 39% Azolla meal, 7% turmeric, 10% corn flour, and 5% tapioca flour; and P3, consisting of 25% snail meal, 51% Azolla meal, 9% turmeric, 10% corn flour, and 5% tapioca flour. The analyzed parameters included protein, moisture, fat, ash, crude fiber, and carbohydrate contents. Data were analyzed using analysis of variance followed by the Least Significant Difference test. The results showed that feed formulation significantly affected all proximate parameters. P3 produced the highest protein content of 43.87%, fat content of 3.68%, crude fiber of 3.11%, and carbohydrate content of 7.28%, while also producing the lowest ash content of 28.46%. Moisture content ranged from 1.11% to 1.30%, indicating good feed storage stability. These findings demonstrate that the integration of snail meal, Azolla, and turmeric can improve the nutritional quality of alternative Nile tilapia feed and support locally based sustainable aquaculture feed development.

Abstract

The use of local raw materials in Nile tilapia feed formulation needs to be developed to reduce dependence on increasingly expensive conventional feed ingredients. This study aimed to analyze the effect of different formulations of chicken feather meal and moringa leaf meal with turmeric addition as a phytobiotic on the chemical composition of Nile tilapia (Oreochromis niloticus) feed. The study used a completely randomized design with three treatments and three replications. P1 consisted of 55% chicken feather meal, 25% moringa leaf meal, 5% turmeric, 10% corn flour, and 5% starch; P2 consisted of 40% chicken feather meal, 40% moringa leaf meal, 5% turmeric, 10% corn flour, and 5% starch; and P3 consisted of 25% chicken feather meal, 55% moringa leaf meal, 5% turmeric, 10% corn flour, and 5% starch. The parameters analyzed were crude protein, moisture, ash, crude lipid, crude fiber, and carbohydrate. Data were analyzed using analysis of variance followed by the least significant difference test when significant differences occurred. The results showed that P3 produced the highest protein content (22.60%), ash content (6.65%), crude fiber (6.55%), and carbohydrate (8.45%), whereas P2 produced the highest lipid content (6.54%). Based on chemical analysis, P3 was the most prominent formulation for most proximate parameters. However, this formulation cannot be directly concluded as the best feed for fish growth because digestibility, palatability, feed conversion ratio, growth, survival, and health responses were not evaluated. Further biological testing is therefore required to confirm its feasibility for Nile tilapia culture.

Abstract

Penelitian ini bertujuan untuk menganalisis hubungan antara kualitas pakan dengan intensitas respon estrus sapi potong pada sistem peternakan rakyat di Kecamatan Pulubala Kabupaten Gorontalo. Penelitian menggunakan pendekatan kuantitatif dengan desain observasional dan metode korelasional. Sampel penelitian sebanyak 57 ekor sapi potong betina yang dipilih menggunakan teknik purposive sampling berdasarkan kriteria tertentu, yaitu sapi dalam umur reproduktif, tidak bunting, sehat, dan dipelihara secara tradisional. Data dikumpulkan melalui observasi dan kuesioner, kemudian dianalisis menggunakan statistik deskriptif dan uji korelasi Rank Spearman. Hasil analisis deskriptif menunjukkan bahwa kualitas pakan memiliki nilai rata-rata sebesar 2,3088 yang berada pada kategori sedang menuju baik, sedangkan intensitas respon estrus memiliki nilai rata-rata sebesar 2,4947 yang berada pada kategori sedang menuju kuat. Hasil uji normalitas menunjukkan bahwa data tidak berdistribusi normal, sehingga digunakan analisis non-parametrik. Hasil uji korelasi Spearman menunjukkan nilai koefisien sebesar 0,080 dengan signifikansi sebesar 0,555 (p > 0,05), yang berarti tidak terdapat hubungan yang signifikan antara kualitas pakan dengan intensitas respon estrus sapi potong. Kesimpulan penelitian ini adalah kualitas pakan tidak memiliki hubungan yang signifikan terhadap intensitas respon estrus sapi potong pada sistem peternakan rakyat. Hal ini menunjukkan bahwa intensitas respon estrus dipengaruhi oleh berbagai faktor lain yang lebih kompleks, seperti kondisi fisiologis ternak, manajemen reproduksi, dan kemampuan deteksi estrus. Oleh karena itu, peningkatan produktivitas reproduksi ternak memerlukan pendekatan yang lebih komprehensif dan terpadu.

Abstract

This study aimed to determine the size at first sexual maturity (L50) of Stolephorus indicus in the waters of North Gorontalo and to analyze its relationship with gonadal maturity through biological and statistical approaches. A total of 2,061 specimens were randomly collected from lift-net (bagan perahu) catches, after which each fish was measured for total length and dissected to identify its gonadal maturation stage. The proportion of mature individuals within each length class was then analyzed using a logistic curve to estimate the L50 value, representing the size at which 50% of the population reaches reproductive maturity. The results revealed a clear sigmoid pattern, indicating a positive correlation between body size and the proportion of mature fish; most individuals smaller than 4 cm were immature, while a significant increase in maturity occurred within the 4.5–6.5 cm size range. The estimated L50 of 5.42 cm suggests that a portion of the population is being harvested before reproducing, emphasizing the need for management measures such as implementing a minimum mesh size of 7 mm and establishing a minimum legal catch size of ≥6.5 cm to reduce juvenile exploitation and support the sustainable management of anchovy resources in North Gorontalo waters.
