Abstract

The aim of this study is to evaluate this commercial product in relation to the preservation materials, the preserved product biomass, individual weight and length of the fronds, and the effect of soaking time and water temperatures on the frond “crispiness”. There was no significant difference between different soaking times (from 30s to 2 minutes) on the weight and the length of the fronds ANOVA (p=0.88) and (p=0.81) after the initial period. Furthermore, tap water and ice water treatments during rehydration process had no significant effect on the fronds crispiness (ANOVA p=0.560). These results show that the preserved product using high concentration of brine produces a product with consistent biomass, size, and amount of the fronds. However, the temperature of the freshwater used in rehydration has no effect on the quality of the product, in contrast to the claims made by the company on the packaging instructions

Abstract

Species of sea grapes (Caulerpa spp.) are consumed broadly in many regions such as in Southeast Asia and Pacific areas. However, it damages easily if packed incorrectly and may only last for couple of days. A company in Vietnam (Tritin Pty Ltd) has developed a preservation technique for sea grapes that enables export to many countries. The aim of this study is to characterization of the Vietnamese company’s product of Caulerpa. The study found that the product based on a 10% brine concentration (114.33 g/L ±2.30 SD). The average weight of each sachet package is 22.47 g ±0.37 containing 65 fronds of Caulerpa lentillifera. The average weight and length of the fronds is 0.73 g ±2.30 SD and 7.27 cm ±1.59 SD. There was a significant relationship between the weight and the length of the fronds during the rehydration process in freshwater (R2=0.35, p<0.01), with rehydration of weight and length complete after x seconds

Abstract

Traditional brackishwater aquaculture in Indonesia focuses on production of shrimp and milkfish. However, since the 1990’s production of shrimp, particularly Penaeus monodon, has become problematic because ofthe prevalence of white-spot disease. Crop losses due to white-spot disease have limited production of P. monodon in traditional tambak throughout Indonesia. Because of this, many tambak have fallen into disuse, or their use islimited. In response, we are developing and trialling diversification options for tambak farmers in Aceh and South Sulawesi. Alternative production options that we are evaluating include Nile tilapia (ikan nila) and soft-shell crab(kepiting lunak) in Aceh, and Nile tilapia, swimming crab (rajungan) and rabbitfish (baronang) in South Sulawesi. In Aceh our main focus has been on Nile tilapia (Oreochromis niloticus) culture, either alone or co-cultured with milkfish (Chanos chanos). We have undertaken trials with farmers in Samalanga and Jangka (Kab. Bireuen) and Banda Mulia (Kab. Aceh Tamiang). Overall, our trials have shown that tilapia will grow and survive well at salinities below 20 ppt. Above 20 ppt, growth rate is reduced and the fish are prone to bacterial disease. At salinities above 20 ppt, milkfish (bandeng) perform better in ponds than tilapia. Our trials in Aceh have demonstrated that Nile tilapia can provideincome to farmers comparable with shrimp culture. Out of a total of 22 trials to date, 9 ponds (41%) have met or exceeded our reference profitability of IDR 1–5 million per hectare per crop. Fourteen ponds (64%) have been‘profitable’, i.e. have generated positive economic returns. This figure is similar to the profitability figure for traditional shrimp ponds (64–73%), indicating that Nile tilapia culture in brackishwater ponds provides economic returns similar to traditional shrimp culture. Based on these results, we recommend Nile tilapia culture to farmers whose ponds are 20 ppt. This provides a profitable production option for farmers in areas subject to low salinities, or during the rainy season when salinities are depressed. Because outbreaks of white-spot disease are particularly common and severe during the rainy season, Nile tilapia culture provides a viable option for income generation for Acehnese tambak farmers under conditions where shrimp culture is too risky

Abstract

ABSTRAKKeberhasilan pertumbuhan anggur laut Caulerpa lentillifera yang dikultur bersama dengan udang windu ditentukan oleh posisi yang tepat untuk menerima nutrien secara maksimal. Penelitian ini bertujuan untuk mengevaluasi pertumbuhan anggur laut dan udang windu pada posisi tanam di dasar dan lepas dasar di dalam tambak tradisional masing-masing dengan 10 ulangan.. Hapa berukuran 1x1 m dan nampan 25x25 cm digunakan untuk memelihara kedua spesies ini. Selama masa pemeliharaan 35 hari, udang windu tidak diberi pakan buatan untuk mempertahankan tipikal tambak tradisional sebagai pemasok bahan pangan organik. Uji t independen mengindikasikan Laju Pertumbuhan Spesifik (LPS) anggur laut dan udang windu di dasar tambak (1,98 ± 0,32% dan 3,68±0,11% per hari) secara signifikan (p0.05) lebih tinggi dibandingkan lepas dasar (1,59±0,29% dan 3,50±0,31% per hari). Sementara itu, Efisiensi Reduksi Nutrien (ERN) dari Total Amonia Nitrogen (TAN) sebesar 38,53±4,48% yang mengindikasikan kemampuan C. lentillifera menyerap bahan anorganik. Studi menyimpulkan bahwa ko-kultur C. lentillifera dan udang windu memiliki efek sinergitas yang positif dan dapat dikembangkan di tambak tradisional. Untuk hasil yang lebih baik, disarankan C. lentillifera ditanam pada dasar tambak dan dikultur bersama dengan udang windu.Kata Kunci: anggur laut, ko-kultur, pertumbuhan, tambak tradisional, udang winduABSTRACTThe successful growth of sea grapes Caulerpa lentillifera co-cultured with tiger prawns is determined by the appropriate position to absorb maximum nutrients. This study aims to evaluate the growth of sea grapes and tiger shrimp in bottom and off-bottom planting position in traditional ponds with 10 replicates each.  Hapa 1x1 m and trays of 25x25 cm were used to rear these two species. During the 35-day rearing period, tiger shrimp were not artificially fed to maintain traditional ponds typical of organic food suppliers. The independent t-test indicated that the Specific Growth Rate (SGR) of sea grapes and tiger prawns at the bottom (1.98 ± 0.32% and 3.68 ± 0.11% day-1) were significantly (p0.05) higher than off the bottom (1.59±0.29% and 3.50±0.31% day-1). Meanwhile, the Nutrient Reduction Efficiency (ERN) of Total Ammonia Nitrogen (TAN) was 38.53 ± 4.48%, which indicated the ability of C. lentillifera to absorb inorganic materials. The study concluded that the co-culture of C. lentillifera and tiger shrimp had a positive synergistic effect and could be developed in traditional ponds. For better results, it is recommended to plant C. lentillifera at the bottom of the pond and co-culture with tiger shrimp.Keywords: co-culture, growth, tiger prawns, sea grapes, traditional pond

Abstract

Keberadaan ekosistem pesisir, seperti mangrove, apabila dikelola dengan baik maka dapat memberi manfaat bagi masyarakat utamanya masyarakat sekitar. Namun tidak adanya edukasi terkait pemanfaatan ekosistem mangrove sehingga terkadang masyarakat tidak terlalu peduli dan cenderung melakukan aktivitas ekstraktif yang dapat merusak fungsi ekosistem mangrove. Desa Sanjai merupakan salah satu desa yang terletak di pesisir Kabupaten Sinjai dan memiliki ekosistem mangrove yang selama ini tidak dikelola dengan baik. Berdasarkan permasalahan tersebut maka program pengabdian ini bertujuan untuk meningkatkan pengetahuan dan keterampilan masyarakat terkait pemanfaatan ekosistem mangrove melalui konsep yang terintegrasi dengan prinsip Sustainable Development Goals yang merupakan program nasional. Metode pengabdian yang dilakukan yaitu ceramah dan dialog. Berdasarkan hasil pretest dan posttest serta menunjukkan bahwa terdapat peningkatan pengetahuan dan motivasi dari peserta, yang terdiri dari tokoh masyarakat, kepala dusun, dan pemerintah desa, untuk mengelola ekosistem mangrove dengan prinsip-prinsip yang berkelanjutan seperti penerapan ekowisata, diversifikasi produk perikanan, dan penyediaan jasa transportasi perahu. The existence of coastal ecosystems, such as mangroves, if managed properly can provide benefits to the community, especially the surrounding community. However, there is no education related to the use of the mangrove ecosystem so that sometimes people do not really care and tend to carry out extractive activities that can damage the function of the mangrove ecosystem. Sanjai Village is one of the villages located on the coast of Sinjai Regency and has a mangrove ecosystem that has not been managed properly. Based on these problems, this service program aims to improve community knowledge and skills related to the use of mangrove ecosystems through an integrated concept with the principle of Sustainable Development Goals which is a national program. The service method used is lecture and dialogue. Based on the results of the pretest and posttest and shows that there is an increase in the knowledge and motivation of participants, consisting of community leaders, hamlet heads, and village governments, to manage mangrove ecosystems with sustainable principles such as the application of ecotourism, diversification of fishery products, and the provision of services. boat transportation for fishing activities

Abstract

A study of the mangrove ecosystem, gastropod community structure, and the influence of hydrooceanography at three district station points on Selayar Island was carried out from March to April 2017. This research aims to show mangrove density in various conditions, to reveal the structure of the gastropod community. and the influence of hydrooceanography. This research was analyzed using the Shannon Wiener index variation method and The Principle Component Analysis (PCA). Overall research findings show: 1) mangrove density values at three station points, namely: a) station 1 (0.35); b) station 2; and c) station 3 (0.16); 2) gastropod density values, namely: a) station 1 (3.44); b) station 2 (3.00); c) station 3 (2.81). The highest relative and absolute frequency value of all stations is Littorina Scabra and the lowest is Terrebralia Pallustris. The diversity index value for gastropod species at various stations ranges from 1.00 to 1.45 and the unity index value ranges from 0.25 to 0.31, which is still relatively low. The distribution pattern of gastropods classified as community groups at each station ranged between 2.53-8.53. The results of the Principle Component Analysis show that gastropods at each station are influenced by environmental factors (Hydro Oceanography).
