Abstract

The Population-Oriented Development Index (IPBK) is an important indicator for measuring regional development success, focusing on human resource quality. This study aims to project the IPBK for 2024–2026 and identify the best method for projecting the IPBK in Gorontalo Regency. The projection methods used are single and double exponential smoothing. The IPBK data for Gorontalo Regency was obtained from the 2024 BKKBN Central Publication. The variables include participation (X1), sustainability (X2), inclusiveness (X3), holistic integration (X4), equality (X5), and IPBK (X6). The data was analyzed using Minitab 16 software. The results indicate that the double exponential smoothing method outperforms the single exponential smoothing method for projecting the IPBK and its dimensions in Gorontalo Regency, achieving a MAPE value of less than 10\%. The IPBK projections and its dimensions for 2024–2026 using the double exponential smoothing method show an annual upward trend, predicting that by 2025–2026, Gorontalo Regency's IPBK status will rise from category 3 (upper-middle status) to category 4 (high status). This high status indicates that Gorontalo Regency has achieved significant progress in key indicators reflecting the welfare and quality of life of its residents.

Abstract

Grouper (Family Serranidae) is one of the betanodavirus hosts. Betanodaviruses can infect species in tropical, subtropical or cold climates. This is a major concern because it has been reported to infect a variety of marine fish, both farmed and wild fish. The disease caused by this virus is commonly known as Viral Nervous Necrosis (VNN) or Viral Encephalopathy and Retinopathy (VER). This VNN disease is characterized by vacuolar necrosis of cells found in the brain, retina and spinal cord, can cause up to 100% mortality in larvae and juveniles and can cause significant losses in older fish. Infected fish, both wild and farmed, can act as reservoirs (nesting sites and breeding grounds for viruses) and can be a source of infection for farmed species. The method used in this study was descriptive method, while the Lunar-Tailed grouper (Variola sp.) samples used in this study were groupers caught measuring 26-42 cm. VNN testing on groupers by taking target organs (brains and eyes) then fixing them in 95% Ethanol then PCR testing at the Virology Laboratory. The results of this study indicate a different prevalence in the two waters in Gorontalo.

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

Yellowstripe scad (Selaroides leptolepis) is an economically important small pelagic fish that supports coastal livelihoods and local food supply in Morowali, Central Sulawesi. Increasing fishing pressure in Banda Sea waters requires location-specific biological information to guide sustainable management. This study analyzed length-frequency distribution, length-weight relationship, growth pattern, and condition factor of yellowstripe scad landed in Bete-Bete Village, Bahodopi District, Morowali Regency. Sampling was conducted from March to May 2026 using 450 individuals obtained from local fishers, with approximately 150 fish sampled each month. Total length ranged from 138 to 203 mm, and catches were dominated by the 171–190 mm size range, especially the 178–183 mm and 184–190 mm classes. Length-weight relationships showed strong positive associations, with coefficients of determination ranging from 79.88% to 94.79%. Growth was generally isometric across sex and month, except for male fish in March, which showed negative allometric growth. Condition factor values were mostly above 1.0 and generally ranged from approximately 1.0 to 1.4, indicating good physiological condition and sufficient habitat support. The findings indicate that yellowstripe scad in Banda Sea waters around Morowali remain in relatively healthy biological condition. However, precautionary management is still required through minimum catch-size regulation, improved gear selectivity, and routine landing-site monitoring.

Abstract

Nile tilapia farming in floating net cages in Lake Limboto provides economic benefits for local communities, yet it operates within an ecosystem affected by lake shallowing, low water transparency, high phosphate concentration, and organic matter accumulation. This study analyzes aquaculture feasibility by integrating ecological, technical, social, and economic dimensions. A descriptive quantitative and qualitative approach was applied. Data were collected through water quality measurement, observation of farming practices, interviews, questionnaires involving 30 respondents, and secondary data review. Economic analysis covered 25 farmers with complete cost and revenue records using the Revenue Cost Ratio. The results show that temperature, pH, dissolved oxygen, nitrate, and nitrite remain supportive of tilapia culture. In contrast, water depth, transparency, phosphate, and organic matter are major ecological constraints. Technically, local farmers are familiar with floating net cages, while access to seed and feed is adequate. Social support is also strong, as 90.0 percent of respondents reported community support and 93.3 percent stated that aquaculture contributes to household income. Average production cost was IDR 7,524,000 per cycle, revenue was IDR 10,508,000, and profit was IDR 2,984,000. The Revenue Cost Ratio of 1.40 indicates economic feasibility, with 24 of 25 businesses classified as feasible. These findings reveal a clear imbalance between economic profitability and ecological pressure. Nile tilapia farming in Lake Limboto is therefore conditionally feasible and should only be developed through aquaculture zoning, stocking control, feed efficiency, and regular water quality monitoring.
