Abstract

The addition of spirulina platensis to fish feed can increase fish growth and fish immunity. This research was conducted using a completely randomized design method with three treatments and three replications. Treatment A (control), Treatment B (addition 6g of Spirulina platensis/1kg of feed), Treatment C (addition 12g of Spirulina platensis/1kg of feed). The results showed that treatment C had better results than other treatments, where the daily growth rate was 3.29%, the feed efficiency was 58.96%, and the survival rate was 100%. This study showed that the addition of 12g of Spirulina platensis was able to increase survival growth rate and feed efficiency of catfish for 30 days of rearing, this addition was still possible to increase the dose of spirulina to the most appropriate dose, considering that the addition of the difference with treatment B gave significant results.

Abstract

Fish farming is an aquaculture activity to maintain fish from larvae to become economic size with providing profit and maintaining of fish population. Analysis of the problems faced by tilapia in the flowing pond system needs to be carried out because it will focus on solving problems. In this study, the analysis used was descriptive qualitative method, where the data came from respondents who were entrepreneurs of tilapia farming. The data obtained from the interviews were divided into three theme groups, first, a discussion of water sources, second, concerning cultivation systems, third, concerning market and capital. The results indicate that the source of cultivated water has no significant problems, some respondents stated that the watervang dam irrigation water source was closed for repair in 2018 for five months, it was stopped for one cycle of tilapia farm activation. The aquaculture system used is still a traditional system with little technology used, the main problem is feed price and the monopoly carried out by "Bos Pakan". The average respondents is owning pond or workers, they just buy tilapia fingerling, when feed and the market is regulated by the partner “boss of feed. This condition make selling price of fish and the price of feed can monopolized by partner “bos pakan”. Suggestion is needs regulation from governments to manage this problem.

Abstract

Fish is one of the commodities needed by the community to meet the needs of animal protein which has high nutritional value, so that treatment is needed to maintain the quality of the fish so that it is still alive and fresh when marketed. The pandemic period becomes an obstacle to maintaining marketing patterns in the regions so that to support the economy and welfare of fish farmers, marketing is carried out by distributing them to other areas using transportation patterns. Transportation is a means for fish farmers to market fish to consumers. The purpose of this research is to describe the transportation pattern of shipping the harvested fish to the area, the process of keeping the fish alive, how long it takes to bring the fish to their destination. The method used in this research is a case study method and sampling using secondary data. The results of the research obtained information to distribute the yields of goldfish cultivation in Musi Rawas Regency using a pick-up car which has a carrying capacity of about 800 kg. the media used is a plastic fish bag using oxygen. The physiological condition of the fish after traveling about 7 hours is still categorized as very good, seen from the active movements of the fish, as well as the morphology of the fish such as eyes, scales, and giblets. The selling price of goldfish after reaching consumers is around Rp. 28,000 / kg . The price of fish is not always stable in the market, one of the causes is high feed prices, weather factors and distribution in the field

Abstract

Fishery activities especially inland fishery is highly affected by community purchasing power. This interaction is seemly looked clearly due to fish becomes one of daily main protein of people. Happening the pandemic of Covid-19 starts in the middle March 2020 in Indonesia directly affects the social activities of people. This research was aimed at analysing the economic impacts resulted in by the Covid-19 pandemic on inland fishery aquaculture in Lubuklinggau City. Data were gathered on September to October 2020 using interviews. Respondents in this research were defined purposively consisting of fish pond owners and aquaculture practitioners of three main fish commodity in this city such as tilapia, carp, and catfish. The gathered data were qualitatively analysed to confirm descriptively the real condition in this city. The results of this study indicate that the inland fish production in the city during the Covid-19 pandemic is till normal. However, the fish commodity demands experience decrease significantly both fresh and life fish. This decreasing demands directly influence the selling price of fish in the fishermen level. The main causes of this event due to the elimination of crowded social activities like an activity gathered mass and face-to-face education activities. A decrease of selling price, in 18% of the Covid-19 on the normal prices before the pandemic happening, is burdensome highly on the aquaculture fishermen in Lubuklingau City. The lower peak of this decreasing price occurred on September 2020 and this condition would be still taken place until the end of this year. The proper policy is needed in order to maintain the aquaculture activities in this city going forward.

Abstract

Budidaya ikan lele memulai dari beberapa fase, diantaranya fase pemijahan, penetasan, pendedearan juvenil, benih dan pembesaran. Perubahan fase dari pendederan menuju pembesaran mengharuskan adanya perpindahan atau proses transportasi. Proses transportasi akan berhubungan denga jarak dan waktu, sementara proses ini akan membuat ikan berada dalam plastik packing yang memiliki keterbatasan oksigen dan dibawa dalam keadaan tertutup. Kondisi transportasi ini akan menjadi masalah terutama pada keberlangsungan hidup ikan, jika tidak diketahui jumlah konsumsi oksigen benih ikan dan lamanya waktu puasa ikan. Penelitain dilakukan sebagai penelitian pendahuluan sebelum melakukan proses transportasi. Hasil dari penelitian ini akan menjadi dasar dalam melakukan lama (jam) proses transportasi ikan lele yang mungkin dilakukan. Perlakuan pada penelitian ini adalah perlakuan puasa ikan, dengan kepadatan 20 ekor diulang sebanyak tiga kali dan dilakukan selama tujuh hari. Perlakuan lainnya adalah mengukur tingkat konsumsi oksigen dari benih ikan lele, ikan lele akan di masukan dalam wadah beriisi air 3ℓ dan diaerasi kencang mencapai DO 6, nilai DO benih ikan lele diukur setiap jam dan dilihat konsumsinya selama enam jam. Hasil penelitian menunjukkan benih ikan lele ukuran 8-10cm mampu bertahan tanpa makan selama tujuh hari atau lebih, namun mulai hari ke-4 ikan mulai berenang lemas, yang menindikasikan ikan mulai kekurangan energi. Tingkat Konsumsi Oksigen benih ikan lele adalah 0,07 mgO2/g/jam. Berdasarkan data yang didapat benih ikan lele mampu ditransportasikan selama 1-3 hari dengan konsumsi oksigen 504 mgO2/g/jam dengan bobot biomasa benih 100g selama 72 jam (tiga hari).

Abstract

This study aims to examine community perceptions of tofu industry waste management in Giriharja Hamlet, Sumedang Regency, as well as the role of anaerobic wastewater treatment plants (WWTP) in supporting environmental sustainability and aquatic resources. Data were collected through observation, interviews, questionnaires, and literature reviews using a qualitative descriptive approach. Respondents consisted of 52 local residents and tofu producers. The findings indicate that prior to the implementation of the anaerobic WWTP, the community faced environmental disturbances, including unpleasant odors from liquid waste. After the WWTP was established, liquid waste was processed into biogas, benefiting 88 households as an alternative to LPG, and its effluent was safely discharged into the environment. Solid tofu waste was also utilized as livestock feed, providing economic value to both the community and tofu producers. The anaerobic WWTP successfully reduced COD levels by over 90%, enhanced environmental quality, and generated renewable energy. Community perceptions of waste shifted from negative to positive, recognizing waste as a valuable new resource. The study underscores that technology-based waste management is crucial for mitigating environmental impacts, supporting the circular economy, and contributing to sustainable development goals, particularly in clean water access, renewable energy, and community welfare.

Abstract

Ekosistem padang lamun merupakan salah satu komponen penting di wilayah pesisir tropis karena memiliki fungsi ekologis sebagai habitat, daerah asuhan (nursery ground), dan sumber pangan bagi berbagai biota laut, sekaligus bernilai ekonomis sebagai penopang aktivitas perikanan tangkap maupun pariwisata bahari. Namun, kondisi padang lamun di banyak wilayah Indonesia menunjukkan tren penurunan yang cukup signifikan akibat kombinasi faktor alami dan antropogenik. Penelitian ini bertujuan untuk menganalisis dinamika perubahan luasan padang lamun di Pulau Pannikiang, Kabupaten Barru, dalam periode 2013–2018, serta menyusun strategi pengelolaan berkelanjutan yang melibatkan peran serta masyarakat dan pemangku kepentingan. Data yang digunakan meliputi citra satelit SPOT 6 tahun 2013 dan Sentinel-2A tahun 2015–2018 yang kemudian diolah melalui analisis klasifikasi supervised serta didukung oleh data lapangan. Hasil analisis menunjukkan penurunan luasan lamun dari 240,91 ha pada tahun 2013 menjadi hanya 15,04 ha pada tahun 2018, dengan total kehilangan seluas 225,87 ha. Penurunan tersebut didorong oleh faktor alami, seperti arus dan gelombang kuat, serta aktivitas manusia, seperti destructive fishing, pembuangan limbah, peningkatan sedimentasi, dan tekanan wisata bahari. Analisis SWOT mengungkapkan bahwa strategi prioritas pengelolaan yang dapat diterapkan antara lain penetapan alat tangkap ramah lingkungan, penguatan pengawasan kawasan, konservasi berbasis masyarakat, pelatihan ekowisata dan kebun bibit lamun, serta penataan zona pemanfaatan yang adaptif. Penelitian ini menegaskan pentingnya pendekatan kolaboratif lintas sektor dan berbasis data ilmiah dalam upaya perlindungan dan pengelolaan ekosistem lamun. Rekomendasi yang dihasilkan diharapkan dapat menjadi rujukan bagi pemerintah daerah, masyarakat lokal, maupun stakeholder lain dalam menjaga keberlanjutan sumber daya pesisir di Pulau Pannikiang.Seagrass ecosystems are an important component of tropical coastal ecology because they serve as habitats, nursery grounds, and food sources for various marine biota, as well as providing economic value as a support for fishing activities and marine tourism. However, the condition of seagrass meadows in many regions of Indonesia shows a significant downward trend due to a combination of natural and anthropogenic factors. This study aims to analyze the dynamics of changes in seagrass meadow area on Pannikiang Island, Barru Regency, during the period 2013–2018, and to develop a sustainable management strategy involving the participation of the community and stakeholders. The data used include SPOT 6 satellite imagery from 2013 and Sentinel-2A from 2015–2018, which are then processed through supervised classification analysis and supported by field data. The analysis showed a decline in seagrass area from 240.91 ha in 2013 to only 15.04 ha in 2018, with a total loss of 225.87 ha. This decline was driven by natural factors, such as strong currents and waves, as well as human activities, such as destructive fishing, waste disposal, increased sedimentation, and marine tourism pressure. The SWOT analysis revealed that priority management strategies that could be implemented include establishing environmentally friendly fishing gear, strengthening area surveillance, community-based conservation, ecotourism training and seagrass nurseries, and structuring adaptive utilization zones. This study emphasizes the importance of a collaborative, cross-sectoral approach based on scientific data in efforts to protect and manage seagrass ecosystems. The resulting recommendations are expected to serve as a reference for local governments, local communities, and other stakeholders in maintaining the sustainability of coastal resources on Pannikiang Island.
