Penelitian ini bertujuan untuk mengetahui pengaruh pemotongan organ tubuh udang lobster yang terbaik terhadap persentase moulting dan kelangsungan hidup lobster air tawar (Cherax quadricarinatus). Penelitian ini dilaksanakna pada bulan April sampai dengan bulan Juni 2020 di Labortaorium Akuakultur Fakultas Pertanian, Universitas Prof. Dr. Hazairin, SH Bengkulu. Penelitian dilaksanakan selama 60 hari. Wadah yang digunakan berupa keranjang plastik berukuran panjang 29 cm lebar 19 cm dan tinggi 11cm sebanyak 20 unit. Jumlah lobster yang digunakan untuk setiap wadah adalah 3 ekor, dengan ukuran panjang rata-rata awal 9 – 12 cm/ekor dan berat rata-rata awal 25- 50 gram/ ekor. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Perlakuan tersebut adalah P1 = Tanpa Pemotongan (Normal), P2 = Pemotongan Kaki Renang, P3= Pemotongan Capit dan P4 = Pemotongan Mata (Ablasi). Data dianalisis dengan sidik ragam (Analisys of Varian) dengan taraf uji taraf 5% dan 1%. Bila berpengaruh nyata maka dilanjutkan dengan uji BNT ( Beda Nyata Terkecil) dengan taraf uji 5%. Parameter yang diamati adalah persentase dan kelangsungan hidup. Hasil penelitian menunjukan bahwa pemotongan organ tubuh udang lobster air tawar (Cherax quaddricarinatus) berpengaruh sangat nyata terhadap persentase moulting, namun berpengaruh tidak nyata terhadap kelangsungan hidup. Pemotongan organ tubuh yang terbaik terdapat pada percobaan pemotongan capit dengan persentese moulting 60%. Keberlangsungan hidup dari semua perlakuan yang dicobakan adalah antara 73%- 93%.

Provinsi Bengkulu menghasilkan 250.000 ton ikan setiap tahunnya. Namun, hasil penelitian para ahli menunjukkan bahwa hampir separuh dari total tangkapan ikan akan berakhir menjadi limbah. Limbah ikan tersebut harus dimanfaatkan agar dapat menghindari polusi lingkungan. Penelitian ini bermaksud untuk memanfaatkan limbah ikan rucah menjadi pupuk organik serta melihat pengaruhnya terhadap pertumbuhan dan hasil tanaman jagung manis. Masalah utama dalam pembuatan pupuk organik dari limbah ikan rucah adalah mudah membusuk, sehingga beresiko menyebabkan kegagalan. Solusi yang ditawarkan adalah mengurangi kadar air dalam ikan rucah. Penelitian ini bertujuan untuk mengevaluasi pengaruh kadar air ikan rucah serta dosis pupuk organik ikan rucah terhadap pertumbuhan dan hasil tanaman jagung manis. Penelitian dirancang dengan Rancangan Acak Lengkap dalam 3 ulangan. Faktor yang diuji adalah dua tingkat kadar air yaitu J1: 75% dan J2: 30%. Sebagai pembanding digunakan pupuk kandang: J3. Sedangkan dosis pupuk organik ikan rucah yang diuji adalah dosis 5, 10, 15, dan 20 ton per hektar. Data dianalisa dengan Anova dan dilanjutkan dengan BNT 5%. Hasil utama dari penelitian ini adalah sebagai berikut. Pertama, penggunaan limbah ikan rucah sebagai pupuk organik telah meningkatkan produktivitas jagung manis hingga 4,20 ton/ha lebih tinggi dibandingkan dengan penggunaan pupuk kandang. Kedua, kandungan kadar air ikan rucah yang tinggi memberikan pengaruh yang terbaik terhadap pertumbuhan dan hasil jagung manis. Ketiga, Dosis pupuk organik ikan rucah dosis 5 ton/ha memberikan pengaruh yang berbeda tidak nyata dengan dosis tertinggi yaitu 20 ton/ha terhadap pertumbuhan dan hasil tanaman jagung manis.

Probolinggo, East Java, Indonesia, is an area with a high potential for shrimp aquaculture because these areas meet the criteria for candidate vaname shrimp aquaculture. Probolinggo in tropical regions with stable climate dan sea waves that have the potential for vaname shrimp aquaculture. The analysis required the following data: tidal data, topographic maps, network layouts, and water quality data for shrimp. This research was conducted by using the facilities at the brackish water and Marine Fisheries Laboratory of Probolinggo; an eco-green aquaculture circulation system was modeled and assessed using shrimp pond. First, the survey was located in Probolinggo City area, with coordinates 7° 44? 30.03? S and 113° 13? 58.68?. The methods used hydrological analysis: Water needs analysis for aquaculture irrigation based on the rules given by the Food and Agriculture Organization and water circulation analysis (Feedpedia, 2016). Material strength analysis of the embankments of the model pools: The comparison of area ratio toward embankment type dimension, design of dike and ponds, water filling discharge of brackish-water pond, and stages for ponds model design development. The results of the research suggested that dike should be planned to be as high as 1.5 m at the highest tide. The results of observations and tables of tidal recordings that had been verified then became the primary benchmark for planning the shrimp pond bottom. Based on the results of the analysis, it was found that the tidal height in the study location areas ranged from 2.5 to 3 m. A total of 80% of the area was used for production ponds.

Tempuyung (Sonchus arvensis L.) is known in Indonesia as traditional medicine. This study was conducted to observe diseases that attack tempuyung in organic cultivation. Ten accessions of sowthistle were collected from Dramaga, Cibadak, Cicurug, Lembang, Matesih, Sekipan, Tawangmangu, Batu, Banjararum, and Sumbersekar, with altitudes between 186-1280 m above sea level and rainfall of 988-2573 mm. The research was carried out in the organic experimental field of Cikarawang, IPB, Bogor, with a geographical location of 6o30' - 6o45' SL and 106o30'-106o45´ EL and an altitude of 190 m above sea level. The research location is a lowland with 1618 mm of rainfall during the study. Pest identification was carried out in the Plant Clinic laboratory of the Plant Protection Department of IPB. Disease identification was carried out by taking symptomatic plants, then isolated and grown in PDA media and then identified. The results showed that the disease that attacked the sowthistle in this experiment was caused by the bacterium Pseudomonas sp and fungi Fusarium sp. The disease attack rate ranges from 32 to 60%. Disease attacks were controlled by removing the affected plants and then spraying with turmeric solution in a ratio of 1: 10. Pests that attacked sowthistle were snails, grasshoppers, fruit borer caterpillars, and panicle-sucking insects.

The development of swamp rice varieties tolerant to submergence is an important step in reducing the impact of floods that often occur in swamplands. The objective of this study was to evaluate the response of eight genotypes of swamp rice in the early stages of tillering to submergence stress. The experiment was carried out using a completely randomized design with three replications. Pots filled with swamp soil were used as the growing media and a tarpaulin pond was used to submerge the plants. The swamp rice lines evaluated were UBPR 2, UBPR 6, UBPR 7, UBPR 8, UBPR 10, and UBPR 11 with Inpari 30 variety as the resistance check variety and Batang Piaman variety as the susceptible check variety. The results showed that the genotypes had varying degree growth recovery following the exposure of 10 days of submergence stress. and UBPR 11 tend to recover faster than other genotypes, classified as tolerant based on plant height, and the number of leaves and leaf greenness are moderately tolerant

The objective of this study was to evaluate the response of eight genotypes of swamp rice in the early stages of tillering to submergence stress. The experiment was carried out using a completely randomized design with three replications. Pots filled with swamp soil were used as the growing media and a tarpaulin pond was used to submerge the plants. The swamp rice lines evaluated were UBPR 2, UBPR 6, UBPR 7, UBPR 8, UBPR 10, and UBPR 11 with Inpari 30 variety as the resistance check variety and Batang Piaman variety as the susceptible check variety. The results showed that the genotypes had varying degree growth recovery following the exposure of 10 days of submergence stress. and UBPR 11 tend to recover faster than other genotypes, classified as tolerant based on plant height, and the number of leaves and leaf greenness are moderately tolerant","PeriodicalId":33886,"journal":{"name":"Jurnal Agroqua","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77177865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
