Abstract

Pearl catfish has the main advantage of fast growth. To maximize this growth, one of the things that must be considered is the feed given. The use of factory feed for catfish seeds is common, so it is necessary to use feed raw materials that are around to be used as raw materials for homemade feed. Vegetable waste such as cabbage and tofu dregs can be used as fish feed which is processed into pellets. Cabbage vegetable waste, tofu dregs, bamboo shoots and bran have protein and carbohydrates that can be used for fish growth. This study consisted of 2 stages, namely stage 1 analyzing the comparison between factory feed and homemade feed and stage 2 analyzing the difference in dosage of homemade feed on the growth and efficiency of pearl catfish (C. gariepinus) seed feed. Data were analyzed using 2 independent samples (unpaired) t-test and ANOVA test. The results showed that the provision of factory feed and homemade feed did not have a significant effect on the growth of length, weight, and feed efficiency of catfish fry. Catfish seeds can be fed homemade feed with ingredients from fermented cabbage waste, tofu dregs flour, rebon flour, bran flour, plus vitamins and minerals. The results of the analysis of variance in the treatment of different feed doses (4%, 5%, 6%, 7%, and 10% per fish body weight), had a significant effect on the growth of catfish length and weight, and had no significant effect on feed efficiency. The higher the dose given for the maintenance period of 30 days of catfish fry gave a good effect with the best dose of 10% per fish body weight.

Abstract

Bagan Perahu (Lift Net) is a fishing business that requires a large investment value. The income of this business is uncertain because it relies heavily on catches and the fish season. The risk of uncertainty will affect business income and fishermen's income. This study aims to analyze the economic feasibility of fisheries and fishermen's businesses in Pelita Jaya Bay West Seram Regency, Maluku. The method used in this study is a survey. The results showed that the business carried out is still very profitable, seen from the business income earned by the owner, which is Rp68,548,000/year. Financial analysis shows the value of NPV over the next ten years amounting to Rp241,568,753; the value of IRR is still above the current bank interest rate of 42.98% and the net value of B/C>1, which is 2.58. The average monthly fishermen's income amounted to Rp1,288,311, and the existing income is still far below the UMR of Maluku Province. This is certainly not economically viable.

Abstract

Gouramy (Osphronemus gouramy) is a freshwater fishery commodity with a large enough demand and a fairly expensive price compared to other freshwater fish. The purpose of this study was to determine the effect of temperature on larval quality and growth of gouramy fry. The research method used is an experimental method using a Completely Randomized Design (CRD) consisting of two treatments of water media temperature, namely 1) Treatment A = The temperature of the media follows room temperature (control treatment), and 2) Treatment B = The temperature of the medium was set constant at a temperature of 30ᵒC. Each treatment was repeated six times to obtain 12 experimental units. Research parameter data were analyzed statistically using variance (ANOVA) at a 95% confidence level using the t-test. The results showed that the degree of hatching of gouramy eggs, larval size, absolute growth, relative growth, daily specific growth rate and survival rate of gouramy larvae at room temperature and 30°C were 90.38% and 98, respectively. 76%; 0.54 cm and 0.66 cm; 0.86 cm and 0.87 cm; 157.52% and 133.26%; 3.99% and 3.58%; and 74.78% and 91.22%. The study concluded that eggs incubated at room temperature (25-28°C) and 30°C gave significantly different effects on hatching rates and post-hatching larvae size. Larval rearing at room temperature and 30°C gave no significant effect on absolute growth but significantly different on relative growth, daily specific growth rate and survival rate

Abstract

Plastic waste can be found everywhere, including in the Koto Panjang Dam. As the plastic waste degraded, the microplastic materials may be distributed in the water and it may be accidentally swallowed by omnivorous fishes such as Puntius schawanafeldii. To understand the presence of the microplastic materials in the fish stomach, a research has been conducted in December 2020 - February 2021. The number of P. schawanafeldii captured was 30 using fish net in 3-5 inch mesh size. The fish was dissected and the stomach was removed. Then the stomach content was added with 10% KOH and was incubated for 2 weeks to delute the organic materials. Then was investigated under a binocular microscope to find out the microplastic materials. Results shown the type of microplastic present in the stomach of P. schawanafeldii was namely film, fibre, and fragment. The most common type of microplastic found was film, followed by fragments and fibre. The abundance of microplastic in the stomach of P. schwanafeldii was around 2 – 15,8 particles/fish.

Abstract

Mangrove plant, Sonneratia alba, can be found abundantly in Indonesia. Some previous studies reported phytochemical screening and bioactivity test of Sonneratia sp. as anti-diabetic (in vitro and in vivo analysis). However, phytochemical identification of S. alba leaves and inhibitory activity of α-glucosidase as anti-diabetic have not been reported. The purpose of this study are to identify phytochemical compounds of methanolic extracts S. alba leaves, and to predict inhibitory mechanisms of S. alba leaves against α-glucosidase through in silico analysis. In this study, the research method consists of two steps namely identification phytochemical compounds of methanolic extracts S. alba leaves, and prediction inhibitory activities of phytochemical compounds of methanolic extracts S. alba leaves against α-glucosidase by molecular docking (in silico) analysis. Methanolic extracts S. alba leaves contained orientin, vitexin, luteolin, oleanolic acid and reserpine. Reserpine was identified for the first time in S. alba leaves. Based on in silico analysis, binding energy of orientin, vitexin, luteolin, oleanolic acid, reserpine and acarbose (positive control) against α-glucosidase were -9,7; -9,7; -9,2; -8,6; -10,0 dan -8,3 kcal/mol. This result indicated that compounds inhibited α-glucosidase activities and can be considered as antidiabetic agent.
