Abstract

Produksi budidaya benih ikan nila merah dipengaruhi ketersediaan pakan yang disesuaikan dengan kebutuhan nutrisi benih ikan nila merah. Penelitian ini bertujuan untuk menganalisis pengaruh dari prebiotik berbasis limbah udang dan menentukan dosis optimum sebagai bahan tambahan dalam formulasi pakan buatan untuk meningkatkan pertumbuhan dan kelangsungan hidup benih ikan nila merah (Oreochromis niloticus). Penelitian ini dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan 4 ulangan. Percobaan pemberian pakan dengan penambahan prebiotik berbasis limbah udang meliputi A (0%), B (1%), C (2%), dan D (3%). Hasil penelitian menunjukkan bahwa dosis pemberian prebiotik berbasis limbah udang pada pakan buatan berpengaruh sangat nyata terhadap laju pertumbuhan harian namun tidak berpengaruh signifikan terhadap kelangsungan hidup benih ikan nila merah. Perlakuan C dengan penambahan prebiotik berbasis limbah udang dosis (2%) 2g/100 gram pakan memberikan hasil tertinggi dengan peningkatan laju pertumbuhan harian dengan sebesar 1,23% dan nilai kelangsungan hidup benih ikan nila merah menjadi 92,5%

Abstract

ABSTRACT This study aims to determine the optimum level of addition of chitosan to the feed to increase the growth rate and daily feed consumption of giant gouramy. The method used in this research is an experimental method using a completely randomized design (CRD), which consists of five treatments and four replications. The treatments used were (A) giving 2.5 g/kg chitosan and 5 g/kg probiotics, (B) 5 g/kg chitosan and 5 g/kg probiotics, (C) 7 chitosan, 5 g/kg and 5 g/kg probiotics, (D) 10 g/kg chitosan and 5 g/kg probiotics, (E) without chitosan and probiotics (control). The test fish used were giant gouramy with a length of 7-9 cm and a weight of 7-9 g. The container used was hapa measuring 1 x 1 x 1 m3 as many as 20 pieces with a density of 20 fish for each treatment and 42 days of maintenance. The amount of feed given was 5% of the fish biomass. Data from observations of length and weight were analyzed using Analysis of Variance (ANOVA) with a 95% confidence level, if there was a significant difference, Duncan's multiple distance test was performed. The results showed that synbiotics administration of 7.5 g/kg chitosan and 5 g/kg probiotics on feed gave the best results with the highest absolute length growth of 4,48 ± 0,3 cm, the highest absolute weight growth of 24,03 ± 3,1 g, the highest daily growth rate of 57,20 ± 7,3 %, feed conversion ratio the lowest was 1.6 ± 0,3 and the highest survival was 98,8 ± 3,2 % in giant gouramy.

Abstract

The purpose of this study was to determine the optimum level of addition of chitosan and probiotics in feed to increase the growth rate and daily feed consumption of giant gouramy  (Osphronemus gouramy). The method used in this research is an experimental method of completely randomized design (CRD), which consists of five treatments and three replications. The treatments used were (A) without giving chitosan and probiotics (control), (B) giving chitosan at 7.5 g/kg feed and probiotics at 10 ml/kg feed, (C) giving chitosan at 7.5 g /kg feed and probiotics at 15 ml/kg feed, (D) chitosan at 7.5 g/kg feed and probiotics at 20 ml/kg feed, (E) chitosan at 7.5 g/kg feed and probiotics of 25 ml/kg feed. The parameters measured were absolute length absolute weight, specific growth rate, feed utilization efficiency ratio (EPP), survival rate, and water quality. Data were analyzed using the Anova test at the 5% level. The results showed that the addition of different concentrations of chitosan and probiotics to commercial feeds could affect growth, and EPP but did not affect the survival rate of giant gouramy. The results obtained during the study showed that treatment C with the addition of chitosan of 7.5 g/kg of feed and probiotics of 15 ml/kg of feed resulted in the highest absolute length growth of 4.87 cm, the highest absolute weight growth of 19,35 g, the highest daily growth rate was 46,08%, the feed efficiency was 91,5% and survival rate was 97,78%. Whereas in terms of the effectiveness of treatment B with the addition of chitosan 7.5 g/kg of feed and less probiotics, namely as much as 10 ml/kg of feed, the treatment was as good as treatment C.

Abstract

Tilapia is favored for its rapid growth and adaptability to diverse aquatic environments, making it a widely cultivated fish. In fish farming activities, feed provides the largest contribution to the total production cost. So that farmers must use alternative feed to reduce feed costs. One alternative feed for tilapia that is easy to obtain, affordable and sustainably available is lamtoro leaves. The aim of this research was to determine the effect of adding lamtoro leaf flour to feed at different concentrations on the growth of tilapia (O. niloticus). The average weight of tilapia at the beginning of the study was 5,7 grams. This research was conducted for 40 days starting in May until June 2023, taking place in Kertayasa Village, Cijulang District, Pangandaran Regency. The method used in this research was an experimental method using a completely randomized design (CRD) with 4 treatments and 3 replications, namely treatment A: 100% commercial feed (control), treatment B: commercial feed + 5% lamtoro leaf flour, treatment C: commercial feed + 10% lamtoro leaf meal, and treatment D: commercial feed + 15% lamtoro leaf meal. Parameters observed included daily growth rate (SGR), absolute length growth, and water quality. The results indicated a significant effect (P<0.05) on the daily growth rate (SGR) by incorporating lamtoro leaf flour into the feed. The highest treatment, observed in treatment C at 50%/day, resulted in the maximum absolute length growth of 4.63 cm. The water quality parameters during the study were in the proper range for the life of tilapia (O. niloticus).  Providing lamtoro leaf flour in feed does not have a negative effect on growth and water quality. Keywords: Tilapia fish, lamtoro leaf meal, growth.

Abstract

The increased demand for red tilapia (Oreochromis niloticus) production requires a sufficient supply of high-quality juveniles. Technological innovation is crucial for developing quantifiable, highly productive, efficient, environmentally sustainable, and ecologically sound juvenile production systems. This study aimed to analyse the effect of high stocking density on the growth performance of red tilapia juveniles cultured using ultrafine bubble technology in a recirculating aquaculture system (UFBs-RAS). A completely randomised experimental design was used with four stocking density treatments: one control treatment (4 fish/L with aeration) and three treatments under the UFBs-RAS system at 4, 6, and 8 fish/L densities. Each treatment was replicated four times. The juvenile red tilapia used in this study had an average initial total length of 4.34 ± 0.23 cm and a weight of 1.47 ± 0.31 g. They were obtained from fishpond research at the FINDER UCoE Experimental Station, Universitas Padjadjaran. The findings indicated that UFBs-RAS facilitated optimal production performance, even at the maximum stocking density of 8 fish per liter. The performance metrics comprised a survival rate of 98.75%, a specific growth rate in weight of 4.93 ± 0.062%/d, a specific growth rate in length of 3.88 ± 0.05%/d, a protein efficiency ratio of 2.48 ± 0.02, a feed conversion efficiency of 96.5 ± 0.58%, and a coefficient of variation of 33.7 ± 1.2%. These data validate that incorporating UFBs-RAS is a viable and efficient method to improve the quality and productivity of red tilapia juveniles.

Abstract

This community service activity was carried out in Kertayasa Village, Cijulang District, Pangandaran Regency, as a strategic step in following up on the formulation of the community service program of Universitas Padjadjaran in early 2025. The main problem raised was the economic stagnation in the fisheries sector due to the slow growth rate of gourami fish and the high risk of mortality due to disease, although the enthusiasm for cultivation in the community remains high. As an adaptive solution, this activity encourages commodity diversification through the development of tilapia (Oreochromis niloticus) which has fast-growing characteristics and better environmental resilience. The implementation method was carried out through a participatory qualitative approach, including Focus Group Discussions (FGDs) with BUMDes administrators and the village government, as well as the application of SWOT analysis to formulate a roadmap for sustainable business development. The ultimate goal of this initiative is to increase the managerial capacity of fisheries groups and strengthen the village's institutional commitment in building the "Nila Kertayasa" brand as a superior product integrated with the economic ecosystem of the Green Canyon tourist village.
