Abstract

Limbah pendederan ikan kerapu bebek (Cromileptes altivelis), kaya akan nitrogen (N) dan fosfor (P), berpotensi mencemari lingkungan apabila dibuang tanpa pengolahan. Penelitian ini bertujuan menentukan konsentrasi optimal limbah pendederan tersebut sebagai media kultur Spirulina sp. skala menengah. Limbah disaring (filter 25 µm) dan disterilkan menggunakan autoklaf (121°C, 15 menit, 1 atm) pada konsentrasi 10%, 15%, 20% dan 25%. Kultur dilakukan selama 9 hari dalam wadah fiberglass volume 15 L, diinokulasi dengan kepadatan awal 1 x 106 sel mL-1, diaerasi secara terus-menerus, dan diberikan pencahayaan. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) dengan tiga ulangan untuk mengevaluasi laju pertumbuhan Spirulina sp., penurunan konsentrasi nitrat dan fosfat, serta parameter kualitas air (suhu, salinitas, pH, dan intensitas cahaya). Hasil menunjukkan bahwa perlakuan limbah 20% menghasilkan kepadatan tertinggi (6,43 x 106 sel m L-1) dan efisiensi penurunan konsentrasi nitrat sebesar 96,0% (dari 5,99 ± 0,13 mg L-1 menjadi 0,24 ± 0,05 mg L-1) dan penurunan fosfat sebesar 67,7% (dari 6,66 ± 0,34 mg L-1 menjadi 2,15 ± 0,32 mg L-1). Penelitian ini menunjukkan bahwa limbah pendederan C. altivelis yang disterilisasi efektif digunakan sebagai media kultur Spirulina sp. skala menengah, dengan konsentrasi 20% memberikan hasil pertumbuhan, efisiensi penyerapan nutrien, dan kestabilan kualitas air terbaik, sehingga berpotensi diterapkan sebagai strategi bioremediasi berkelanjutan dalam konsep akuakultur sirkular.Effluent from humpback grouper (Cromileptes altivelis) nursery operations is rich in nitrogen (N) and phosphorus (P), posing a risk of environmental pollution if discharged untreated. This study aimed to determine the optimal concentration of humpback grouper nursery effluent as a rearing medium for Spirulina sp. cultured at an intermediate scale. The effluent was filtered (25 µm) and sterilized using an autoclave (121°C, 15 minutes, 1 atm) at concentrations of 10%, 15%, 20%, and 25%. Spirulina sp. was cultured at an initial density of 1 x 106 cells mL-1 in 15-L fiberglass tanks that were continuously aerated and illuminated for 9 days.  A completely randomized design (CRD) with three replications was used to evaluate the growth rate of Spirulina sp., the reduction of nitrate and phosphate concentrations, and water quality parameters (temperature, salinity, pH, and light intensity). Results showed that the 20% wastewater produced the highest cell density (6.43 × 10⁶ cells mL-1) and achieved a nitrate concentration reduction efficiency of 96.0% (from 5.99 ± 0.13 mg L-1 to 0.24 ± 0.05 mg L-1) and a phosphate reduction of 67.7% (from 6.66 ± 0.34 mg L-1 to 2.15 ± 0.32 mg L-1). This study demonstrated that sterilized effluent from humpback grouper nursery can be used as the rearing medium for Spirulina sp. cultured at an intermediate scale, with a 20% concentration providing optimal growth, nutrient removal efficiency, and stable water quality, thereby supporting its potential use as a sustainable bioremediation and circular aquaculture strategy.

Abstract

Vaname shrimp (Litopenaeus vannamei) is one of Indonesia's leading cultivation commodities in the fisheries sector. The success of the vaname shrimp cultivation business cannot be separated from the water quality parameters, which play a role in supporting their growth and survival rate. Salinity is a water quality variable that plays a very important role in the growth and survival of Vannamei shrimp. The aim of this research was to study the growth and survival rate of vaname shrimp reared at low salinity. The research design used was a completely randomized design consisting of three treatments and four replications. These treatments had media salinities of 1 ppt, 3 ppt, and 5 ppt. Shrimp rearing is carried out in a 40-liter volume container with a stocking density of 40 fish per container, or 1 PL/L. Shrimp farming is carried out for 35 days. The observation parameters carried out during this research were Specific Growth Rate (SGR), Growth Rate (GR), Survival Rate (SR), Feed Conversion Ratio (FCR), Total Vibrio Count (TVC), and water quality in the maintenance media. The research results showed that media salinity of 3 and 5 ppt was the best treatment for increasing the growth and survival rate of vaname shrimp.

Abstract

Peningkatan konsentrasi CO2 di atmosfer menimbulkan dampak efek gas rumah kaca dan mengakibatkan pemanasan global. Karbon biru (blue carbon) merupakan kemampuan ekosistem pesisir dan laut dalam menyerap CO2 secara efektif melalui fotosintesis yang disimpan dalam bentuk biomassa dan sedimen. Tujuan dari penelitian ini adalah menganalisis simpanan karbon di vegetasi mangrove Desa Sungai Nibung. Penelitian dilakukan dari Juni sampai Agustus 2022. Lokasi penelitian di Desa Sungai Nibung, Kabupaten Tulang Bawang, Provinsi Lampung. Pengukuran karbon mangrove pada tegakan mangrove, nekromassa, dan serasah yang dilakukan dengan metode non-destructive sampling. Hasil penelitian menunjukkan karbon tersimpan pada sedimen lebih besar dibandingkan dengan karbon tersimpan pada tegakan, nekromassa, dan serasah. Karbon tersimpan pada sedimen yang tertinggi berada pada sedimen yang memiliki ukuran liat kasar karena liat kasar dapat menyimpan unsur hara yang tinggi.

Abstract

Budi daya lobster cukup berkembang dimasyarakat pesisir. Perkembangan budi daya tidak diikuti dengan perkembangan teknologi budi daya yang baik karena lobster dibesarkan dengan diberi pakan berupa ikan rucah, kerang hijau dan kerang darah. Pengabdian kepada masyarakat  bertujuan untuk menyebarluaskan teknologi pembuatan pakan formulasi yang dapat digunakan pada budi daya lobster dalam karamba jaring apung. Tahap pertama yang dilakukan adalah penyuluhan yang menyangkut aspek bioekologi lobster, budi daya lobster secara umum, pengelolaan lingkungan dan pembuatan pakan formulasi untuk lobster. Tahap kedua adalah demonstrasi proses pembuatan pakan formulasi yang diperkaya dengan vitamin dan hormon. Tahapan ketiga evaluasi selama proses pengabdian kepada masyarakat. Pengabdian dilakukan di Desa Hanura, Kecamatan Teluk Pandan, Kabupaten Pesawaran, Provinsi Lampung dengan peserta adalah nelayan dan pembudi daya ikan. Pengabdian ini memberikan peningkatan pemahaman nelayan dan pembudi daya ikan tentang budi daya lobster dan kemampuan praktis untuk membuat pakan formulasi untuk lobster

Abstract

The Biogas-based energy security program in Kediri Village, Pringsewu District, Lampung Province, aims to provide awareness and knowledge to villagers about the potential of cow dung to be made into biogas and promote awareness of good environment quality. An evaluation of the sustainability of the program in the community was conducted. The methods that were used in this program are (1) socialization to provide awareness of good environment quality and energy security, (2) digester construction and stove and biogas lamp installation, which was carried out by the community together with certified trainers, (3) creation of a master design of the digester layout to ensure the maximum utilization of the digesters, and (4) evaluation to determine opportunities for program sustainability. Results show that the Biogas-based Energy Security Program has succeeded in making the community aware of and accept and apply the technology of processing cow manure into biogas. Biogas has met 100% of the fuel needs for cooking and electricity of biogas-fed houses. The environment quality has also improved, as shown by clean cages and home environments, and methane emissions have reduced. Over the five-year program, 11 out of 20 planned digesters have been built. The program's future sustainability can be continued by the community, provided that alternative sources of funds that can be pursued by the community are available.
