Abstract

This comprehensive study investigates the temporal dynamics and ecological aspects of phytoplankton communities in water reservoirs utilized for Pangasius cultivation. Over a six-week observation period, 25 phytoplankton species, including Bacillariophyceae, Chlorophyceae, Cyanophyceae, Euglenophyceae, and Cryptophyceae, were identified. Chlorophyceae displayed the highest species richness, emphasizing the dominance of this group, particularly Chlorella, which remained stable throughout weekly observations. Other taxa, such as Euglenophyceae, exhibited delayed increases in density. The study revealed two crucial groups in the water reservoir: the first, composed of Actinastrum sp., Closterium sp., Staurastrum sp. (Chlorophyceae), Navicula sp., Pleurosigma sp., Schroedaria sp., Surirella sp. (Bacillariophyceae), and the second, more diverse group consisting of Nitzschia sp. (Bacillariophyceae), Cryptomonas sp. (Cryptophyceae), Trachelomonas sp. (Euglenophyceae), Anabaena sp., Merismopedia sp., Phormidium sp. (Cyanophyceae), Ankistrodesmus sp., Chlorella sp., and Crucigenia sp. (Chlorophyceae). Chlorella was consistently present which was observed to interact with various species, fostering a balanced environment for growth and reproduction within its family and across others based on network analysis. Contradictory dynamics emerge in the initial weeks, where the highest species richness (N = 19 species) coincides with a high dominance index (1/D = 0.54). Conversely, the peak diversity index (H’ = 2.04) occurs during the second observation, aligning with a comparable evenness index (J = 0.89). The saprobic index indicates a shift in pollution levels from β-mesosaprobic to α/β-mesosaprobic between the initial and final weeks of observation. Simultaneously, trophic-saprobic index alterations signify an environmental quality transition from polysaprobic to oligosaprobic. This presents contradictory trends, where, based on species richness, the environment is ecologically classified as polluted. However, considering the contribution of non-indicator groups in the formula, the pond conditions shift towards nutrient impoverishment, suggesting potential suitability for aquaculture practices.

Abstract

Sustainable mangrove management requires community efforts and participation. Where positive community perceptions of the existence of mangroves will increase community participation in mangrove management activities. Several factors that encourage the community to participate are both internal and external factors. This study aims to see the perception and participation of the community towards the mangrove forest ecosystem and recommend sustainable mangrove forest management strategies. The study was conducted from August to September 2024 using qualitative research methods by collecting descriptive data in written or oral form, which were then interpreted descriptively holistically, contextually using researchers as the main instrument for collecting data. To formulate a mangrove management strategy for the sustainability of the mangrove ecosystem, a SWOT (Strengths, Weaknesses, Opportunities and Treaths) analysis was carried out. The results of the study showed that the Alang-Alang Village community had a good and positive perception of the existence of the mangrove forest ecosystem, but their participation was still passive (participating if there was someone to accommodate and not yet their own initiative) in the management and preservation of mangrove forests. Where good community perception and community participation also influenced the good ecology of the Alang-Alang Village mangrove forest, including the area and density of good mangroves. However, there are still individuals from other villages who sometimes still cut down mangrove trees and added high waves and strong tidal currents also damage the existing mangrove forest ecosystem. For the management of the mangrove forest ecosystem, Alang-Alang Village is in quadrant I, where the strategy that can be applied in this condition is to support an aggressive strategy or aggressive growth policy (Growth oriented strategy) by utilizing existing strengths and opportunities

Abstract

The coastal area of Batam Island have a fairly high potential for capture fisheries and contribute to the community's economy, especially in coastal areas. Capture fisheries businesses must pay attention to economic and ecological sustainability. The purpose of this study is to analyze the sustainability of the capture fisheries business on Batam Island based on bio-economic aspects in order to provide an overview of fisheries business management. The analysis was carried out descriptively through the Gordon-Schaefer model approach with the Gordon logistics growth function. The analysis was carried out on three management conditions, namely Maximum Sustainable Yield (MSY), Maximum Economic Yield (MEY), and Open Access Equilibrium (OAE). The results of the study show that the optimal utilization of capture fisheries in the coastal area of Batam Island is around 7,823 units of fishing vessels every year. The production of catch in the Maximum Sustainable Yield condition is around 36,982 tons, in the the Maximum Economic Yield condition is around 36,977 tons, while in the Open Access Equilibrium condition is only around 1,646 tons.

Abstract

Permasalahan utama yang dihadapi oleh pelaku usaha mikro di wilayah perbatasan Indonesia–Filipina adalah rendahnya produktivitas dan terbatasnya volume penjualan produk olahan, terutama pada sektor perikanan. Menjawab tantangan ini, Universitas Terbuka (UT) bekerja sama dengan Sekolah Tinggi Ilmu Komputer (STIK) Rajawali Talaud dan Pemerintah Kabupaten Kepulauan Talaud melaksanakan program Pengabdian kepada Masyarakat (PkM) yang berfokus pada peningkatan kapasitas produksi dan strategi pemasaran produk lokal. Permasalahan teknis seperti metode kerja yang belum efisien menyebabkan volume produksi masyarakat stagnan pada kisaran 3–5 kg per batch. Melalui program ini, dilakukan perbaikan metode produksi, pelatihan, serta optimalisasi proses kerja, yang mampu mendorong peningkatan kapasitas produksi menjadi 10–15 kg per batch sesuai permintaan pasar. Selain itu, dilakukan intervensi pada aspek pengemasan produk agar lebih menarik dan memenuhi standar distribusi yang lebih luas. Dampak signifikan dari kegiatan ini adalah meningkatnya daya saing produk lokal di pasar luar daerah, bahkan hingga menembus pasar ekspor ke Filipina dan Korea Selatan. Program ini menunjukkan bahwa kolaborasi lintas sektor yang terstruktur mampu mendorong pemberdayaan ekonomi masyarakat secara berkelanjutan di wilayah 3T (terdepan, terluar, tertinggal).

Abstract

North Sumatra, a key economic region in Indonesia outside of Java, continues to face persistent challenges such as high unemployment, the dominance of the informal sector, and uneven economic growth. Within this context, Micro, Small, and Medium Enterprises (MSMEs) serve as a cornerstone of the regional economy, particularly through their role in labor absorption and income generation. Despite their significance, MSMEs in North Sumatra still face substantial obstacles, including limited access to financing, inconsistent investment growth, and inadequate policy implementation—factors that hinder their full potential in driving inclusive development. This study examines the dynamic relationship between MSME growth, workforce participation, and Gross Regional Domestic Product (GRDP) in North Sumatra, employing a simultaneous equation model with time-series data from 2009 to 2023. The Two-Stage Least Squares (2SLS) method addresses endogeneity and simulates the effects of policy interventions projected for the 2025–2030 period. The findings indicate that MSME development is significantly influenced by policy instruments such as tax incentives and minimum wage regulations. Increases in wages and tax reductions enhance labor absorption, stimulate MSME performance, and promote GRDP growth. The study provides practical policy insights for strengthening the resilience and sustainability of MSMEs within North Sumatra’s evolving economy.
