Abstract

Mangroves are an ecosystem that has an important function for coastal areas, the existence of mangroves provides ecological, economic, and social functions. Therefore, mangrove ecosystem management must be carried out using an environmental sustainability approach and natural resource sustainability to avoid damage to the existence of the mangrove ecosystem. This research aims to analyze the status of sustainability of mangrove ecosystem management in the Mangrove Hijau Daun area, Daun Village, Sangkapura District, Bawan Island, Gresik Regency. This research was carried out from June to August 2023. The method used was RAPFISH (Rapid Appraisal for Fisheries) analysis with a Multidimensional Scaling (MDS) approach based on ecological, economic, social, and institutional dimensions. The results of the research show that the sustainability status of the mangrove ecosystem in the green leaf mangrove area of Bawean Island obtained a multidimensional index value of 72.56, including in the quite sustainable category, each dimension has an index value, namely the ecological dimension of 88.68, the economic dimension of 49.80. , the social dimension is 78.40, and the institutional dimension is 88.12. The economic dimension is a dimension whose management needs to be encouraged because it has an index value in the less sustainable category.

Abstract

Nowadays, there are still many high capacity generators have not yet protected completely from their internal ground faults. They still rely on differential and over current relays. It is seen that this relay will reduce their sensitivities when applied to generators with high impedance grounding systems. To overcome such problem, a combination protection scheme of the neutral overvoltage (59N) and neutral undervoltage third harmonics (27N3) is developed. This paper aims to design the protection scheme for high capacity generators. This paper demonstrates the designing of neutral grounding transformer (NGT) system, the relay settings and reviewing of their sensitivities. To clarify the concepts this study uses a generator 802 MVA, 22.8 kV as object. The results show that the protection scheme is very effective to protect 100% of generator stator with relays overlapping of 31.5%. It needs NGT transformer with capacity of only 28.33 kVA, 15000/240 V, and the secondary resistor of 0.38,117 kW. This paper can hopefully be used as one reference for protection system engineers to design or develop protection schemes in their fields especially whose generator has not equipped yet with such protection scheme.

Abstract

Lobster pasir (Panulirus homarus Linnaeus, 1758) merupakan jenis spiny lobster yang paling banyak dibudidayakan di Indonesia. Zooplankton menjadi mangsa penting dari spiny lobster dan diduga menentukan keberhasilan budidaya spiny lobster terutama pada fase puerulus dan juvenil awal. Tujuan penelitian ini adalah untuk mendata jenis, indeks keanekaragaman (H’), dan kelimpahan spesies zooplankton di Teluk Ekas pada fase bulan yang berbeda di kedalaman penempatan wadah pemeliharaan puerulus lobster. Sampel zooplankton diperoleh ketika fase bulan gelap dan terang pada bulan Juni-Juli 2021 dari tiga kedalaman penempatan puerulus (0,5 m, 1 m, 1,5 m). Karakteristik morfologi digunakan dalam identifikasi jenis zooplankton menggunakan beberapa buku identifikasi dan konfirmasi nama spesies di website World Register of Marine Species (https://www.marinespecies.org/). Total sebanyak 14 jenis zooplankton diperoleh yang terbagi ke dalam enam kelas yakni appendicularia (1), bivalvia (1), copepoda (3), malacostraca (2), oligotrichea (6), polychaeta (1). Copepoda  merupakan kelompok yang ditemukan paling melimpah dan berpotensi sebagai pakan alamiah dalam budidaya benih spiny lobster. Fase bulan gelap memiliki taksa yang lebih tinggi, dengan keanekaragaman dan kelimpahan zooplankton lebih tinggi di bulan terang pada tiap kedalaman laut pengambilan sampel.

Abstract

Ikan kembung lelaki (Rastrelliger kanagurta) memiliki nilai ekonomis penting bagi nelayan. Tekanan eksploitasi yang tinggi memengaruhi keberadaan stok dan keseimbangan ikan tersebut di alam. Efektivitas pengelolaan perikanan perlu dilakukan, diantaranya melalui kajian struktur stok. Kajian struktur stok dengan analisis genetik dapat menunjukkan status genetik stok dan aliran gen pada setiap stok dalam suatu populasi. Informasi ini dapat digunakan sebagai dasar pengelolaan sumberdaya perikanan. Penelitian ini bertujuan untuk menganalisis keragaman dan struktur genetik, serta struktur stok ikan kembung lelaki di WPP-NRI 711, 572, dan 573 menggunakan pendekatan molekuler. Isolasi dan ekstraksi DNA menghasilkan 20 DNA total per-lokasi (enam lokasi), dan diamplifikasi dengan metode PCR. Terdapat 109 dari 120 sampel hasil PCR yang dilanjutkan ke tahap RFLP. Hasil dari proses pemotongan band tunggal oleh enzim restriksi (RFLP) diidentifikasi menggunakan program Popgene32. Enzim yang mampu menunjukkan polimorfisme yaitu AluI dan HaeIII. Stok ikan kembung lelaki di WPP-NRI 711, 572, dan 573 memiliki kedekatan secara genetik, sehingga mengindikasikan sebagai unit stok tunggal. Namun, jarak genetik yang visualisasikan dengan dendrogram menunjukkan stok membentuk dua clade yang terpisah. Dalam pengelolaannya lebih baik menjadi unit manajemen terpisah untuk kepentingan statistik.

Abstract

Keberadaan fitoplankton diduga berdampak besar terhadap keberhasilan budidaya lobster terutama di fase pertumbuhan benih bening (puerulus) menjadi juvenil. Lobster pasir (Panulirus homarus) merupakan salah satu spesies spiny lobster yang paling banyak dibudidayakan di Indonesia khususnya di Teluk Ekas, Lombok.  Tujuan penelitian ini adalah untuk mendata jenis, kelimpahan, indeks keanekaragaman (H’), dan  spesies fitoplankton yang potensial sebagai harmful algal blooms (HABs), pada kedalaman penempatan wadah pemeliharaan puerulus lobster di Teluk Ekas pada fase bulan yang berbeda. Sampel fitoplankton diperoleh dari tiga kedalaman penempatan puerulus (0,5 m, 1 m, 1,5 m), ketika fase bulan gelap dan terang pada bulan Juni-Juli 2021. Hasil penelitian menunjukkan tercatat total 53 jenis fitoplankton yang terbagi ke dalam lima kelas yakni Bacillariophyceae (13), Coscinodiscophyceae (10),  Cyanophyceae (1), Dinophyceae (9), dan Mediophyceae (20). Tujuh genus fitoplankton tergolong dalam harmful species (Chaetoceros sp., Dinophysis sp., Nitzschia sp., Skeletonema sp. Trichodesmium sp., Tripos sp. dan Protoperidinium sp.). Fase bulan gelap memiliki kelimpahan fitoplankton yang lebih tinggi dibandingkan bulan terang pada tiap kedalaman laut pengambilan sampel. Fitoplankton paling berlimpah pada lapisan permukaan air laut dan menurun seiring penambahan kedalaman dengan H’ yang bervariasi dan fluktuatif. Analisis kesamaan memperlihatkan bahwa kedalaman 1 m memiliki persen kesamaan yang tinggi dengan kedalaman 1,5 m.

Abstract

The coastal waters of Eretan located in the north of Indramayu Regency are used as fishing grounds by local fishermen. The condition of water input, especially from the surrounding river waters, namely the Cimanuk River, Cipunagara River, and Perawan River, is thought to affect the condition of coastal waters. This study aims to analyze the trophic level based on water quality conditions. Data collection on the quality of the aquatic environment was carried out in three locations with purposive sampling considerations, namely the Cipunagara estuary, the Perawan estuary, and the Cimanuk estuary. Sampling was carried out in two different seasons, namely the dry season and the rainy season. The method used in the analysis is the TRIX Index based on nutrients, phosphate, chlorophyll-α, and DO saturation. Meanwhile, water quality parameters at each location were analyzed using principal component analysis (PCA). The results of the study showed that the main water quality parameters tended to differ in each season. The trophic level at the three locations had values between 4.99 and 8.59, so they had mesotrophic to hypertrophic status. This shows that coastal water conditions need to be managed so that water conditions are more stable.

Abstract

Genetic-based management is a critical approach to maintain the sustainability of mahseer fish (Tor tambra and T. tambroides), which are facing threats from habitat degradation and overfishing in Jambi Province. This study aims to analyze the genetic diversity and population structure of mahseer using the COI gene markers. A total of 18 specimens were collected from six locations in the Jambi rivers (June-August 2024). DNA sequencing results showed 98.51–99.85% similarity to the references T. tambra and T. tambroides in GenBank. Phylogenetic analysis confirmed the grouping of this species, with a bootstrap value of 100% and closeness to the species Barbonymus gonionotus and Hampala macrolepidota. There were 11 haplotypes with the highest diversity at stations 3 and 6 (Hd= 0.90000), while moderate genetic differentiation (Fst= 0.109–0.141) was found between station 2 and other locations, indicating isolation due to habitat fragmentation. Water quality parameters (dissolved oxygen 6.3–7.1 mg/L, pH 7.0–7.3, current velocity 0.2–0.4 m/s) support habitat suitability, but anthropogenic activities potentially threaten genetic connectivity. These findings underscore the need for genetic data-driven conservation strategies, such as restocking of highly diverse populations and protection of critical habitats. Further research is needed to monitor long-term genetic dynamics.

Abstract

This study aims to analyze the implementation of digital education innovation based on Total Quality Management (TQM) in Islamic Boarding Schools in the Bangka Belitung Islands. This study uses a qualitative approach with a case study design, where data is collected through interviews, observations, and documentation, then analyzed descriptively with the Interactive Analysis Model from Miles & Huberman, including data reduction, data display, and data verification. The study results indicate that the commitment of Islamic boarding school management is significant in providing adequate digital infrastructure for learning. Implementing TQM in Islamic boarding schools requires the involvement of all elements of the school, including managers, teachers, and students. Designing a digital-based curriculum that integrates local wisdom also plays a role in maintaining Islamic boarding school values while meeting the demands of technological developments. In addition, enhancing resource capacity, especially teachers, through technology training is the key to success in implementing digital media. Focusing on user satisfaction, both students and teachers, is also essential to ensure the success of digital learning. The implications of this study indicate that implementing digital-based TQM in Islamic boarding schools not only strengthens the quality of education but also introduces a technology-based approach relevant to the needs of the times without ignoring the traditional values of Islamic boarding schools.

This research is conducted to analyze the biological aspect and the usage status of blue swimming crab (Portunus pelagicus) on the coast of Pangkajene dan Kepulauan regency. Data collection used a survey method by conducting interviews with fishermen, observing research sites and measuring crabs directly in the field. Samplings were obtained twice a month from November 2018 to April 2019. 7200 Portunus crabs from the fisherman were randomly selected to measure the size and the weight which consists of 3900 male and 3300 female crabs from different districts were Pangkajene, Bungoro, Labakkang, Ma’rang, Segeri, and Mandalle. The measurement result are then analyzed using Microsoft Excel program and ELEFAN I method in FISAT II program. The result showed that the maximum age of blue swimming crab predicted can reach 4 years, with the natural mortality (M) of Portunus male crabs is 0.67 and female crabs 0.82 per year then fishing mortality (F) is 3.54 and 4.12 per year. The total mortality (Z) is 4.20 and 4.94 per year with the exploitation rate (E) around 0.84 and 0.83. Therefore, based on the system dynamics model of non-equilibrium fish biomass resulted that the biology status of blue swimming crabs on Pangkep regency has reached the overfishing condition.
