Abstract

This study aims to determine the effect of dragon fruit peel meal utilization in the diet to improving the color quality of freshwater crayfish (Cherax quadricarinatus). This research was done from May to June 2022 at the Lampung State Polytechnic Fisheries Laboratory. The test animals used were freshwater crayfish with an average weight of 6.7 6.8 g/crayfish and a stocking density of 7 crayfish/aquarium. Feeding with a feeding rate of 3% twice a day. The experimental design used was a completely randomized design with 5 treatments and 3 repetitions. The treatments were A = commercial feed (control), B = 5% dose, C = 10% dose, D = 15% dose, E = 20% dose. The parameters observed in this study were an increase in color quality and water quality. The results of this study indicate that the difference in the dose of red dragon fruit peel meal in the diets can have a significant effect on the color brightness of freshwater crayfish (86.01 in claws and 87.59 in Chepalotorax to teslon). The conclusion of this research is that supplementation of red dragon fruit peel meal mainly at a dose of 10% in the feed can improve the color quality of freshwater crayfish from brown to bluish color.Keywords:Dragon fruit peel meal UtilizationDietColor qualityCherax quadricarinatus

Abstract

Vannamei shrimp (Litopenaeus vannamei) holds significant economic importance in Shrimponesia as a prominent shrimp commodity. The post-larval stage often encounters challenges, primarily due to the shrimp's limited ability to adapt and survive in a new environment. Stocking density is a crucial factor influencing the growth and production performance of vannamei shrimp culture. This study aims to assess the optimal stocking density for achieving optimal growth and survival in L. vannamei. A 40-day maintenance trial was conducted at UD Mina Rahayu Kalianda to investigate the impact of different stocking densities on water quality in the maintenance media. The study utilized containers with varying stocking densities: treatment A (1 shrimp/L), treatment B (1.5 shrimp/L), and treatment C (2 shrimp/L), each with three replications. The findings revealed survival rates (SR) of 83.33% for treatment A, 62.78% for treatment B, and 58.33% for treatment C. Mean Body Weight (MBW) values were recorded as 1.2592 g/shrimp for treatment A, 1.1216 g/shrimp for treatment B, and 0.7728 g/shrimp for treatment C. Average Daily Growth (ADG) results showed 0.0313 g/shrimp for treatment A, 0.0279 g/shrimp for treatment B, and 0.0192 g/shrimp for treatment C. Based on the study, the recommended stocking density for white vannamei shrimp is 40 shrimp/L, demonstrating improved growth and survival rates for this species.

Abstract

Pantai Prestasi yang berada di kawasan Politeknik Pelayaran Banten memiliki potensi besar sebagai destinasi wisata unggulan bagi masyarakat Tangerang dan Jakarta, namun pengembangannya saat ini masih terhambat oleh masalah penumpukan sampah di tepi pantai. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mewujudkan konsep eduwisata melalui sosialisasi dan aksi nyata penanaman mangrove dengan melibatkan masyarakat Desa Karang Serang serta taruna-taruni Kementerian Perhubungan. Metode pelaksanaan yang diterapkan mencakup tahapan survei, penyuluhan materi keilmuan, diskusi interaktif, serta praktik lapangan penanaman bibit mangrove secara langsung di pesisir pantai. Hasil kegiatan menunjukkan adanya peningkatan pemahaman kolektif peserta mengenai manfaat ekologi dan ekonomi mangrove, serta terciptanya komitmen bersama dalam menjaga kebersihan lingkungan pantai guna meningkatkan nilai jual kawasan tersebut sebagai objek wisata. Secara keseluruhan, program kolaborasi ini berhasil menginisiasi transformasi Pantai Prestasi menjadi kawasan eduwisata yang asri dan berkelanjutan.   Pantai Prestasi, located within the Banten Merchant Marine Polytechnic area, possesses significant potential as a premier tourist destination for the people of Tangerang and Jakarta, yet its development is currently hindered by the accumulation of waste along the shoreline. This community service activity aims to realize the concept of edutourism through socialization and concrete action of mangrove planting, involving the community of Karang Serang Village and cadets from the Ministry of Transportation. The implemented methods include survey stages, scientific material counseling, interactive discussions, and direct field practice of planting mangrove seedlings on the coast. The results of the activity indicate an increase in the participants' collective understanding of the ecological and economic benefits of mangroves, as well as the establishment of a shared commitment to maintaining the coastal environmental cleanliness to enhance the area's value as a tourist object. Overall, this collaborative program successfully initiated the transformation of Pantai Prestasi into a beautiful and sustainable edutourism area.
