Tiger prawns are one of the export commodities that have a high price in Tarakan City North Kalimantan Province. Tiger prawns are needed by consumers increasing from year to year. Suryanto and Tarakania (2009) stated that world consumer demand for tiger prawns increased by around 11.5% per year. The opportunity for tiger shrimp 1) to determine the cost of tiger prawn aquaculture in Tarakan City. 2) to find out the receipting tiger prawns quaculture in Tarakan City. 3) to find out the income of tiger prawns aquaculture in Tarakan City. This research wan conducted in Tarakan city, North Kalimantan Province. The number of respondents 15 farmers who have a land area (aquaculture) of 1 to 50 hectares and have been running for two years. This research employed a sampling method, namerly Snowball Sampling ,where the subject provides a referral to recruit the samples needed for research studies. Data collection was done through observation, interviews, and documentation. It was carried out by processes such as stocking tiger prawns seeds in ponds, maintenance, harvesting, and total harvesting. The data was used to calculate the income of tiger prawn farmer using income analysis. The research result showed the total production costs, revenues, and income of tiger prawn farmers, namely the average production cost of Rp.12,249,121 for the months, one harvest with an average pond area of 16.2 hectares. The average receiving was Rp.24,410,066 and the average income is Rp.12,160,945. It can be concluded that tiger prawn farmers have a significant advantage in their pond areas in Tarakan City.

Pengkayaan pakan alami menggunakan ekstrak daun karamunting (Melastoma malabathricum L) secara signifikan berpengaruh nyata pada laju pertumbuhan post larva udang windu (Penaeus monodon). Penambahan ekstrak daun karamunting pada pakan buatan belum diujicobakan, maka perlu dilakukan untuk melihat pengaruh ekstrak daun karamunting terhadap laju pertumbuhan udang windu yang dipelihara di tambak tradisional. Penelitian ini yang bertujuan untuk mengevaluasi penambahan ekstrak daun karamunting pada pellet pada laju pertumbuhan udang windu (Penaeus monodon) yang dipelihara di tambak tradisional. Penelitian ini menggunakan rancangan penelitian ekperimental, terdiri dari dua perlakuan dan lima ulangan. Perlakuan yang diberikan adalah pemberian pelet komersil dan pelet komersil yang diperkaya dengan ekstrak. Dosis ekstrak daun karamunting yang diberikan adalah 150 mg/kg pelet. Pemeliharaan udang windu dilakukan selama 90 hari, sampling panjang dan bobot udang diamati per 30 hari. Hasil yang diperoleh menunjukkan pengkayaan pakan pellet dengan penambahan ekstrak daun karamunting berpengaruh pada laju pertumbuhan udang windu dibandingkan dengan perlakuan kontrol. Diperoleh nilai pertumbuhan panjang dan bobot yang lebih tinggi yaitu; 8,05 cm dan 34 g pada perlakuan, sedangkan perlakuan kontrol adalah 6,25 cm dan 18 g. Nilai kelangsungan hidup udang windu, berkisar antara 73-100% untuk perlakuan ekstrak sedangkan untuk kontrol berkisar antara 60-80%. Dapat disimpulkan daun karamunting mampu meningkatkan laju pertumbuhan dan sintasan hidup udang windu. Natural feed enrichment using melastoma leaf extract (Melastoma malabathricum L) significantly affects the growth rate of post-larval tiger prawns (Penaeus monodon). The addition of melastoma leaf extracts to artificial feed has never been tested. It is necessary to see the effect of melastoma leaf extract on the growth rate of tiger prawns reared in traditional ponds. This study aimed to evaluate the addition of melastoma leaf extract to pellets on the growth rate of tiger prawns (Penaeus monodon) reared in conventional ponds. This study used an experimental research design consisting of two treatments and five replications. The treatment given was the administration of commercial pellets and commercial pellets enriched with extracts. The dose of melastoma leaf extract given was 150 mg/kg pellets. The carried out maintenance of tiger prawns was for 90 days. The sampling of the length and weight of the shrimp every 30 days. The results obtained showed that enrichment of pelleted feed with the addition of melastoma leaf extract affected the growth rate of tiger prawns compared to the control treatment. The higher length and weight growth value was 8.05 cm and 34 g in the treatment, while the control treatment was 6.25 cm and 18 g, respectively. The survival value of tiger prawns ranged from 73-100% for the extract treatment, while the control ranged from 60-80%. Can conclude that melastoma leaves can increase tiger prawns' growth rate and survival.

Udang windu di Kota Tarakan mempunyai potensi sumberdaya perikanan yang cukup besar, sehingga menjadikan kota Tarakan sebagai salah satu sentra produksi udang windu di Indonesia. Penelitian ini bertujuan untuk mengetahui kontaminasi bakteri pada udang windu (Penaeus monodon ) di Hatchery Kota Tarakan. Penelitian ini dilaksanakan pada bulan Mei – Juni 2021. di Labolatorium Balai Karantina Ikan, Pengendalian Mutu dan Keamanan Hasil Perikanan Tarakan ( BKIPM Tarakan ) dengan sampel udang windu (Peneus monodon) yang meliputi Sterilisasi alat dan bahan, Isolasi bakteri, identifikasi bakteri dan analisis data. Metode yang digunakan pada penelitian ini yaitu dengan studi observasional untuk memberikan gambaran mengenai penelitian yang dilakukan dengan mengamati kondisi – kondisi yang terjadi melalui observasi secara langsung. Hasil penelitian dengan melakukan analisis karakterisasi bakteri dengan uji biokimia pewarnaan gram negatif, katalase positif, oksidase positif, OF tanpa paraffin fermentatif, motility positif, indol negatif, ornitin positif, TSA tegak dan miring asam. Dapat disimpulkan hasil karakterisasi bakteri dan uji biokimia bahwa terdapat 16 isolat bakteri yang mengkontaminasi udang windu pada hatchery di kota Tarakan. Tiger prawns in Tarakan City have a large enough potential for fishery resources, making the city of Tarakan as one of the centers for tiger shrimp production in Indonesia. This study aims to determine the bacterial contamination of Vibrio spp. on tiger prawns (Penaeus monodon) in the Tarakan City Hatchery. This research was conducted in May – June 2021. at the Laboratory of the Fish Quarantine, Quality Control and Safety of Fishery Products Tarakan (BKIPM Tarakan) with samples of tiger shrimp (Peneus monodon) which includes sterilization of tools and materials, isolation of Vibrio bacteria, Vibrio bacteria and analysis data. The method used in this research is with observational studies to provide an overview of the research conducted by observing the conditions through direct observation. The results of the study were carried out by analyzing the characterization of bacteria with gram negative staining tests, positive catalase, positive oxidase, OF without fermentative paraffin, positive motility, negative indole, positive ornithine, upright TSA and acid skew. Can lock the results of bacterial characterization and biochemical tests that there are 16 isolates of Vibrio spp. which contaminate tiger prawns in hatcheries in the city of Tarakan.
