Abstract

GMO is a product of biotechnology through genetic engineering techniques. This can be done to increase food availability and reduce production costs, especially by manipulating the genes and chromosomes of cultivated species. In invertebrates such as shrimp, the application of gene transfer is still limited to the recognition and expression of foreign genes and focuses on increasing disease resistance. Among several gene transfer methods (microinjection, electroporation and transfection), transfection method is the most effective method to be applied to shrimp. It is characterized by high hatching data and is not toxic. In addition, the use of GMO in aquaculture is a highly controversial issue due to many environmental and health issues. This journal will discuss gene manipulation by means of gene transfer to improve shrimp culture.

Abstract

Vaname shrimp (Litopenaeus vannamei) cultivation is growing rapidly in Indonesia and has various production scales, from traditional to super-intensive. This study examines the technical and economic differences of each production scale based on literature studies. Technically, the traditional scale still relies on natural environmental conditions with a stocking density of 5–9 shrimp/m2 and a productivity of 0.1–0.5 tons/ha/period. The traditional-plus scale is a development of the traditional scale with several improvements in technical aspects such as pond bottom soil processing, additional feeding, and simple water quality management with a stocking density of 10–49 shrimp/m2 and a productivity of 0.7–1.5 tons/ha/period. The semi-intensive scale begins to implement better aeration and water quality management, increasing the stocking density to 50–79 shrimp/m2 with a productivity of 4–8 tons/ha/period. At intensive and super-intensive scales, the use of technologies such as biofloc systems, Recirculating Aquaculture Systems (RAS), and Internet of Things (IoT) allows for higher stocking densities (80-150 shrimp/m2 and 250-400 shrimp/m2) with productivity reaching 15-20 tons/ha/period and 100-150 tons/ha/period. Economically, a more intensive production scale shows greater benefits. The traditional scale has an Internal Rate of Return (IRR) of 10-20% with a payback period of 3-5 years, while the semi-intensive and intensive scales have an IRR of 20-50% with a shorter payback period (1.5-3 years). The super-intensive scale offers the highest benefits with an IRR> 50%, a Net Present Value (NPV) of billions of rupiah, and a payback period of less than 1.5 years. However, intensive and super-intensive scales require large initial capital and more complex management systems, especially in terms of water quality and biosecurity. The results of this study indicate that increasing the scale of production can increase efficiency and profits, but also carries higher risks. Therefore, the selection of production scales must consider technical readiness, financial resources, and good risk management. The application of technologies such as biofloc, RAS, and IoT has the potential to increase the efficiency and sustainability of whiteleg shrimp cultivation. Support from the government and stakeholders is needed to increase the competitiveness of the aquaculture industry through policies that support innovation and sustainability.

Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh padat tebar terhadap pertumbuhan ikan nila dalam berbagai sistem akuakultur. Metode penelitian yang digunakan adalah studi kepustakaan, dengan mengumpulkan dan menganalisis data dari berbagai penelitian terdahulu yang relevan. Hasil penelitian menunjukkan bahwa padat tebar memiliki pengaruh signifikan terhadap pertumbuhan, kelangsungan hidup, dan kesehatan ikan nila. Padat tebar yang terlalu tinggi dapat menyebabkan persaingan sumber daya, stres, dan penurunan kualitas air, yang berdampak negatif terhadap pertumbuhan ikan. Sebaliknya, padat tebar yang terlalu rendah dapat mengakibatkan pemanfaatan ruang yang tidak optimal. Padat tebar optimal bervariasi tergantung pada sistem budidaya yang digunakan. Pada sistem ekstensif, padat tebar disesuaikan dengan ketersediaan pakan alami, sedangkan pada sistem semi intensif dan intensif, padat tebar yang lebih tinggi dapat diterapkan dengan pengelolaan kualitas air dan pakan yang lebih baik.

Abstract

Abstrak Perluasan budidaya ikan menggunakan sistem keramba jaring apung (KJA) di Danau Batur, Bali telah menimbulkan berbagai tantangan lingkungan, antara lain eutrofikasi, sedimentasi, penurunan kualitas air, serta konflik dengan sektor pariwisata dan pemangku kepentingan budaya. Studi ini bertujuan untuk menganalisis secara sistematis potensi sistem informasi geografis (SIG) sebagai alat bantu pengambilan keputusan dalam pengelolaan KJA yang berkelanjutan di Danau Batur, Bali, Indonesia. Dengan menggunakan metode tinjauan pustaka yang terstruktur, studi ini mengevaluasi penerapan SIG dalam penataan ruang budidaya perairan pada berbagai sistem perairan tawar di Indonesia dan wilayah internasional yang sebanding. Analisis mengidentifikasi variabel biofisik dan sosio-spasial utama yang penting untuk penempatan KJA secara optimal, seperti kedalaman air, kadar oksigen terlarut, arus perairan, kedekatan dengan zona sensitif, serta akses terhadap infrastruktur. Studi kasus dari Danau Toba, Danau Maninjau, dan Waduk Cirata menunjukkan efektivitas SIG dalam menentukan zona budidaya yang sesuai, mengevaluasi daya dukung lingkungan, dan mengurangi konflik pemanfaatan ruang. Meskipun memiliki potensi tinggi, pemanfaatan SIG di Danau Batur masih terbatas akibat lemahnya koordinasi kelembagaan, kurangnya integrasi data spasial, dan rendahnya keterlibatan pemangku kepentingan. Studi ini menyimpulkan bahwa SIG, jika dipadukan dengan pemetaan partisipatif dan selaras dengan kerangka regulasi, dapat mendukung tata kelola budidaya yang transparan, ekologis, dan sensitif terhadap nilai budaya. Artikel ini juga memberikan rekomendasi untuk membangun sistem zonasi berbasis SIG, meningkatkan mekanisme perizinan dan pengawasan, serta mengintegrasikan data lingkungan dan sosial-budaya dalam pengambilan keputusan spasial. Temuan ini berkontribusi pada penguatan perencanaan budidaya berkelanjutan di Danau Batur dan danau-danau dataran tinggi lainnya di Indonesia.   Abstract The rapid expansion of fish farming using the floating net cage (FNC) system in Lake Batur, Bali, has given rise to various environmental challenges, including eutrophication, sedimentation, declining water quality, and conflicts with the tourism sector and cultural stakeholders. This study aims to systematically analyze the potential of Geographic Information Systems (GIS) as a decision support tool for sustainable FNC management in Lake Batur. The study uses a systematic literature review to examine relevant GIS applications in aquaculture zoning across freshwater systems in Indonesia and comparable international contexts. The analysis identifies key biophysical and socio-spatial variables essential for optimal cage placement, such as water depth, dissolved oxygen, current flow, proximity to sensitive zones, and infrastructure access. Case studies from Lake Toba, Lake Maninjau, and the Cirata Reservoir demonstrate the effectiveness of GIS in delineating suitable aquaculture zones, evaluating environmental carrying capacity, and reducing spatial conflicts. Despite its high potential, the use of GIS in Lake Batur remains limited due to weak institutional coordination, a lack of integrated spatial datasets, and minimal stakeholder engagement. This study concludes that when coupled with participatory mapping and aligned with regulatory frameworks, GIS can support transparent, ecologically sound, and culturally sensitive aquaculture governance. The paper recommends establishing GIS-based zoning, improving licensing and monitoring systems, and integrating environmental and socio-cultural data into spatial decision-making. These findings contribute to advancing sustainable aquaculture planning in Lake Batur and other highland lake systems in Indonesia.

Abstract

The Upaya Mina Group in Banyuasih, Sumedang, cultivates common carp using a running water pond system but faces challenges due to rising feed costs that are not matched by the selling price of fish. This community service activity aims to provide a solution through the implementation of a polyculture system combining common carp and Nile tilapia to improve feed efficiency. The method used involved educational outreach through demonstrations and pilot trials at the group’s aquaculture site. The trial results showed that the polyculture system produced 810 kg of fish with a feed efficiency of 76%. In comparison, the group’s previous monoculture system yielded only 640 kg with a feed efficiency of 59%, despite using the same amount of feed, which was 1 ton. The implementation of the polyculture system increased production by 170 kg and feed efficiency by 17%. Thus, the polyculture system not only boosts production but also offers a practical solution to the problem of high feed costs.

Abstract

Tilapia filet is a fishery product that is widely favored because of its high protein content and ease of processing. However, this product has a relatively short shelf life, so natural preservation efforts are needed to extend its shelf life. This study aims to determine the optimal concentration of vinegar in the fermentation process of cassava peels to extend the shelf life of red tilapia fillets based on the number of bacteria during low-temperature storage. This research was carried out at the Fisheries Product Processing Laboratory, Biotechnology Laboratory, Aquaculture Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University in February 2024. This study was carried out by soaking red tilapia fillets using a fermented solution of cassava peel with different vinegar concentrations, consisting of 5 treatments, namely 0%, 0.5%, 1%, 1.5%, 2% and stored at low temperatures (50-100 C). The parameters observed were the number of bacterial colonies, and the degree of acidity (pH). The concentration of 0% observation was carried out on the 1st, 3rd, 6th, 7th, 8th, 9th day while the concentration of 0.5%, 1%, 1.5%, 2% was observed on the 1st, 4th, 7th, 8th, 9th, 10th, 11th, 12th and 13th days. Based on the results of the research that has been conducted, it can be concluded that a fermented solution of cassava peel with a vinegar concentration of 1% is the best to prolong red tilapia fillets based on the number of microbes and pH. The addition of 1% cassava peel fermentation solution can maintain the freshness of the fish until the 12th day with a total number of microbes of 3.3 x 107 with a pH value of 6.70

Abstract

Insecticides can be used to overcome pest attacks in agricultural and plantation sectors. The botanical insecticide is more widely used because more friendly to the environment than chemical insecticides. Neem is one of the plants that can be used as basic ingredient for botanical insecticides because it contains the compound azadirachtin. Insecticide enter the cultivation area because carried by flowing water. Tilapia is a fish that can be used as a bioindicator of pollution levels, water quality, and changes in the aquatic environment. This study aims to determine the effect of exposure insecticide with azadirachtin active ingredient on growth and survival rate of tilapia. This research was conducted in March and August for the preliminary test and September-October 2022 for the main test at Ciparanje Inland Aquaculture Hatchery, Padjadjaran University. The fish used in this study averaged 6,70 ± 0,014 cm. This study used experimental method, Completely Randomized Design with five treatments and three replications. The treatments used were exposure to insecticides with different doses, namely A(0 ppm), B(26.25 ppm), C(52.5 ppm), D(78.75 ppm), E(105 ppm). Parameters observed included absolute length growth and weight growth, survival rate, and water quality until 28th day. Growth and survival data analyzed using the F test and continued with Duncan's test at the 95% level of confidence. The results showed that exposure insecticide can inhibited growth and affected the survival of tilapia. Treatment C(52.5 ppm) is a safe concentration for the survival of tilapia and the highest growth is the treatment without addition of insecticide.

Abstract

This research aims to examine the effect of exposure to plant-based insecticides containing active ingredients eugenol and azadirachtin on the survival and growth of common carp (Cyprinus carpio). The study was conducted from September to October 2022 at the Ciparanje Inland Fisheries Hatchery, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The research method used was an experimental method, and the experimental design employed was a completely randomized design (CRD). The study included six treatments with three replications. The test fish used were Majalaya strain common carp fingerling, measuring 7-8 cm, obtained from the Cibiru Fish Seed Center in Bandung City. The treatments examined in this study were Treatment A (0 ppm), B (12.8 ppm), C (25.6 ppm), D (38.4 ppm), E (51.2 ppm), and F (64 ppm). The insecticides were administered once at the beginning of the research in the water, which served as the maintenance medium, according to the treatment concentrations. The parameters observed were survival rate, growth, and water quality. Observations were conducted for 28 days after the application of the plant-based insecticides. The highest percentage of survival was found in Treatment A (control) at 100%, while the lowest percentage of survival was observed in Treatment F (64 ppm) at 81.7%. The highest absolute length growth was recorded in Treatment A (control) at 2.73 cm, and the lowest absolute length growth was observed in Treatment F (64 ppm) at 1.97 cm. The highest weight growth was observed in Treatment A (control) at 4.2 g, and the lowest absolute weight growth was found in Treatment F (64 ppm) at 2.6 g. The research indicates that the growth and survival of common carp fingerling (Cyprinus carpio) decrease due to the influence of exposure to plant-based insecticides containing active ingredients eugenol and azadirachtin.
