Abstract

Guna menghadapi permasalahan tentang ketersediaan pakan karena peningkatan harga, salah satu upaya yang dapat dilakukan adalah dengan menggunakan pakan alternatif pengganti. Pakan alternatif pengganti yang dapat digunakan adalah dengan memanfaatkan sumberdaya yang ada di sekitar lokasi budidaya. Potensi kelimpahan jenis ikan yang ada di Teluk Ekas dapat digunakan sebagai pakan bagi lobster dengan penangkapan secara langsung menggunakan alat tangkap yang ramah lingkungan. Penggunaan alat tangkap ikan ini diharapkan dapat menunjang ketersediaan pakan selama proses budidaya lobster dan menekan penggunaan pakan buatan. Budidaya lobster di Indonesia masih bergantung pada ikan rucah sebagai pakan utama. Ikan rucah mengandung protein tinggi yang mampu memenuhi kebutuhan protein organisme budidaya untuk mendukung pertumbuhan. Selain itu, harganya terjangkau dan ketersediaannya cukup melimpah. Kelimpahan stok ikan rucah yang tinggi ini belum dimanfaatkan dengan baik oleh para pembudidaya karena keterbatasan alat tangkap yang mendukung, sehingga para pembudidaya hanya mengandalkan hasil tangkapan oleh para nelayan yang setiap hari pergi mencari ikan. Salah satu upaya dalam merespons persoalan untuk mengamankan stock pakan lobster berupa ikan  rucah adalah dengan inovasi teknologi penangkapan ikan menggunakan jaring insang. Para pembudidaya belum memahami bahwa kelimpahan sumberdaya ikan yang ada di sekitar KJA dapat dimanfaatkan sebagai pakan dalam proses budidaya. Kelompok pembudidaya yang tergabung dalam Pokdakkan Pasir Putih diberikan pendampingan melalui penyuluhan dan Focus Group Discussion (FGD) untuk mempelajari, mempraktekkan dan menggunakan jaring insang guna memenuhi stok pakan bagi lobster yang dibudidayakan.

Abstract

Coastal areas are transition between land and marine ecosystems. The coast is an area rich in natural potential which has long been utilized by humans. Changes that occur in coastal and marine areas are generally influenced by human activities in the surrounding areas, resulting in a decline in environmental quality, one of which is the mangrove ecosystem. Mangrove are spread throughout almost all coastal areas in Indonesia. The mangroves in South Lembar Village are directly adjacent to settlements, coastal tourist areas and aquaculture. Therefore, it is necessary to transfer knowledge so that the community of South Lembar Village, especially those on the coast, understand the importance of mangroves for the environment so that they can protect the mangrove ecosystem. The implementation of this community service activity is carried out using the counseling method. This service activity began with a presentation on the importance of the mangrove ecosystem and a question and answer/discussion. The result of this community service was that outreach was carried out with material presented regarding the importance of the mangrove ecosystem, which was attended by the South Lembar Ecotourism Group and the Cemare Eco Green Mangrove Society, the South Lembar Village community, and lecturers from the Aquaculture Study Program. The conclusion of this community service is that information, knowledge and science have been conveyed to the community in Cemare Hamlet, South Lembar Village about the importance of mangrove ecosystems for marine coastal areas.

Abstract

Abstract: Sargassum sp. seaweed is included in the category of brown macro algae that has not been cultivated and has not been optimally utilized. Sargassum sp. has economic value because it contains alginate and iodine which are utilized in the food, pharmaceutical, cosmetic, and textile industries. Sargassum sp. has a high carbohydrate content that can be converted into bioethanol and bioenergy. So that this potential can be developed to improve the community's economy and increase efforts to protect the environment from pollution from the use of fossil fuels. Sargassum sp. seaweed can be found in the waters of Gerupuk, Sengkol Village, Pujut District. Gerupuk is a hamlet that is included in the Mandalika Creative Economic Zone, among the community's livelihood activities is seaweed cultivation. Seaweed farmers in Gerupuk only cultivate K. alvarezii seaweed. They only know Sargassum sp. as a seaweed that grows wild and has no economic value. Sargassum sp. in Gerupuk is not utilized, so it needs to be educated on its benefits and utilization. This community service activity will be carried out in Gerupuk Hamlet, Sengkol Village, Pujut District, Central Lombok Regency. The output targets of this community service activity are appropriate technology for the cultivation of Sargassum sp. for bioethanol production, publications at national community service seminars and articles published in national community service journals indexed by sinta. The stages of implementing this activity are coordination of activities, counseling, demonstration of Sargassum sp. seaweed cultivation, mentoring, evaluation of activities, and collaboration with the Lombok Marine Aquaculture Center (BPBL). The expected results of this activity are that seaweed farmers in Gerupuk can cultivate Sargassum sp. to improve the household economy and the community economy. Keywords: Seaweed, Sargassum sp., cultivation, bioenergy, bioethanol.

Abstract

This study investigates how the addition of Sargassum sp. flour to feed affects the brightness of clownfish color. (Amphiprion frenatus). The experimental method used a completely randomized design (CRD) with five treatments and three replications, resulting in 15 experimental units. The treatments consisting of the addition of Sargassum sp. flour are treatment A (control), treatment B (10%), treatment C (20%), treatment D (30%), and treatment E (40%). Taking three clownfish randomly for each treatment to observe the color development and measure their length and weight every fifteen days on days 0, 15, 30, 45, and 60. Data from observations of color brightness, carotenoid content, and water quality were analyzed descriptively, while data on length and weight growth and survival were analyzed using variance analysis. The research results show that, based on the TCF paper method, Photoshop application, and carotenoid content, the addition of 40% Sargassum sp. flour to the clownfish feed has the greatest effect on the brightness of the clownfish color. There is no significant impact on the survival of clownfish. (Amphiprion frenatus).

Abstract

Mud crab (Scylla spp.) aquaculture holds significant potential in supporting food security, economic growth, and ecological balance. This study aims to summarize various findings related to critical factors in mud crab farming, such as feed types, rearing systems, and stocking density, and their impact on productivity, feed conversion ratio (FCR), and economic profitability. The review highlights that trash fish feed at 15% of body weight yields optimal growth and feed efficiency due to its high protein content. Feed diversification, including stingray and janitor fish, offers promising results with reduced costs. Various rearing systems are employed, ranging from cages and earthen ponds to advanced technologies such as Recirculating Aquaculture Systems (RAS). Small bamboo floating cages demonstrate superior outcomes in growth and survival rates (SR). Mangrove habitats significantly enhance crab growth, while silvofishery systems provide a sustainable farming alternative. Optimal stocking density, such as 4 crabs/m², balances growth and production. Additionally, Scylla serrata exhibits the best growth rate compared to other species, particularly males. Innovations like soft-shell farming technology add economic value to the product. Overall, the success of mud crab aquaculture depends on the optimal combination of feed, rearing systems, and environmental management. This review offers strategic insights for developing efficient, sustainable, and economically viable crab farming practices.

Abstract

This community service activity focused on developing feed production techniques using local raw materials for mud crab farmers in Madak Belek Hamlet, Sekotong District. The main challenge faced by farmers is the high cost of commercial feed, which reduces profit margins. In fact, the area is rich in underutilized nutrient-rich local resources such as trash fish and seafood processing by-products. A participatory approach was applied, including observation, socialization, demonstration, hands-on training, and evaluation. The training emphasized feed formulation and the application of 5% wheat gluten as a binder, which had been proven in preliminary studies to enhance feed stability in water. The results showed an improvement in participants’ knowledge and skills in processing local ingredients into quality feed. The expected impacts include reducing dependence on commercial feed, lowering production costs, and improving the efficiency and sustainability of mud crab farming. For further optimization, feed performance testing on crab growth and economic feasibility analysis are required.
