Abstract

The waters of Lampung Bay have high potential resources for threadfin bream (Nemipterus sp.). This fish has significant economic value as a diverse food ingredient. However, currently, the body size of threadfin bream found tends to be uniform and even smaller due to continuous overfishing. The research was conducted to assess the status of utilization of threadfin bream resources in the waters of Lampung Bay based on five important aspects, namely ecology, economics, social, technological and institutional. The research was carried out in May 2023 at Lempasing Fishing Port, Bandar Lampung City, with data collection through observation and interviews. Data analysis used the multi-dimensional scaling (MDS) method using the Rapfish (rapid appraisal for fisheries) application to evaluate the sustainability of the use of threadfin bream. The results of the analysis show that the sustainability index value for the use of threadfin bream in the waters of Lampung Bay is as follows: ecological dimension 48.59; economic dimension 36.80; social dimension 75.00; technology dimension 49.91; and ethical dimension 61.64. Based on these results, it can be concluded that the use of threadfin bream in the waters of Lampung Bay is quite sustainable, with an average index value of 54.39.Keywords: Ecological dimension, multi-dimensional scaling, Rapfish, sustainability index.

Abstract

Blue swimming crab is a fishery product with high economic value in Indonesia. Betahwalang Village, Demak, is one of the crab fisheries locations in the province of Central Java. High selling prices and processing industry demand encourages fishing activities. One issue brought on by increased fishing activity is the smaller crab size. It will impact the crab fishing industry in Betahwalang. The majority of the fisherman in Betahwalang Village catch crabs using arad nets, simple gill nets, and traps. This study aims to evaluate the size of crab catch results on fishing gear used by fishermen and recommend proper fishing gear for catching crabs. This research was conducted in April 2019. The catch size of crab was the primary data collected for this study, also with data on fishing grounds, methods, and characteristics of fishing gear. Data were collected by observation, interviews, and measurements of fishing gear and the carapace width of the crab. The results of data collection and processing were analyzed descriptively. The results showed that the highest proportion of legal size crabs (carapace width ≥10 cm) was caught in traps, while the proportion of unlegal size crabs caught was mostly in bottom gillnets and mini trawl.

Abstract

Kegiatan budi daya perikanan dengan padat tebar yang tinggi  akan menghasilkan limbah cair dan padat    yang sebagian besar mengandung bahan organik, tingkat kekeruhan, dan padatan tersuspensi yang tinggi. Penerapan teknik fitoremediasi dan filtrasi menjadi salah satu upaya untuk mencegah pencemaran maupun kerugian akibat pembuangan limbah budidaya perikanan dengan cara yang hemat biaya serta ramah lingkungan. Penelitian ini bertujuan untuk mengukur efektivitas melati air sebagai fitoremediator dan filtrasi dalam mengolah limbah organik budidaya perikanan untuk memperbaiki kualitas air sehingga dapat menurunkan kadar limbah. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktor yaitu perlakuan kepadatan tanaman melati air dan waktu pengamatan. Analisis data menggunakan ANOVA (Analysis of Variance) dan uji lanjut Duncan dengan tingkat signifikan 5%.   Hasil penelitian menunjukkan nilai DO berkisar 4,6-6,9 mg/L; pH berkisar 5,24-7,28; suhu berkisar 26,5-30,11 0C; ammonia berkisar 0,0001-0,0045 mg/L dan ammonium berkisar 0,2399 – 1,1898 mg/L; dan nitrat berkisar 1,6-14,75 mg/L. Perlakuan kombinasi kepadatan tumbuhan melati air sebanyak 10 rumpun dan filtrasi efektif dalam menurunkan kadar nutrien (nitrat); dan 5 rumpun untuk menurunkan kadar ammonia dan ammonium. selama 40 hari proses fitoremediasi, tanaman melati air mengalami peningkatan yang signifikan dalam tinggi tanaman, lebar daun, dan jumlah daun. Laju pertambahan tinggi tanaman berkisar antara 0,19 hingga 0,24 cm per hari. Kesimpulan dari prnrlitian ini, yaitu perlakuan kombinasi kepadatan tumbuhan melati air sebanyak 10 rumpun dan filtrasi efektif dalam menurunkan kadar nutrien (nitrat); dan 5 rumpun untuk menurunkan kadar ammonia dan ammonium.
