Abstract

Sea grapes have high economic potential. The development of sea grape cultivation is inseparable from its cultivation techniques. The research objective was to determine the daily growth rate and chlorophyll content of sea grapes in different cultivation techniques. The research was conducted from September to November 2020 at the Polytechnic of Marine and Fisheries, Kupang, East Nusa Tenggara. The treatment in this study was a different cultivation technique with 3 treatments, namely by spreading it (scattering technique), using the substrate (substrate technique), and combining the spread and substrate (combined technique). The results showed no difference in daily growth rate and chlorophyll content even though using different cultivation techniques. The intensity of sunlight more influences the daily growth rate and chlorophyll content. Water quality parameters during the study supported the daily growth rate.

Abstract

Liquid waste is one of the negative impacts of the oil palm processing industry, which can disrupt aquatic ecosystems. This study aims to describe the morphometric conditions of the digestion system of tilapia (Oreochromis niloticus) exposed to palm oil wastewater. The study was conducted from April to July 2020. Tilapia measuring 4-7 cm in length with an average weight of 3-8 grams with 160 fish per treatment. The stages of the research included raising fish, giving oil palm liquid waste, and observing the morphometric digestion system. Fish were exposed to oil palm wastewater with concentrations of 0 mL.L-1, 47 mL.L-1, 70.4 mL.L-1, and 94 mL.L-1 for 64 days. The analysis was carried out on the Gastro Somatic Index (GaSI), Intestine Somatic Index (ISI), Relative Gut Lengths (RGL), Relative Intestine Lengths (RIL), and Hepato Somatic Index (HSI). The results showed that palm oil wastewater could affect the morphometric digestion of tilapia (Oreochromis niloticus). Palm oil wastewater with a concentration of 94 mL.L-1 also affected the GAS of 2.40%, the ISI of 5.49%, and RIL of 549.11%. In the treatment, the concentration of oil palm liquid waste was 70.4 mL. L-1 affected the HSI by 1.70%. However, exposure to palm oil wastewater does not affect RGL. The content of palm oil liquid waste can disrupt the metabolism of the stomach, intestinal, and liver cells. The high concentration of waste can damage the lining of the stomach and intestines, resulting in decreased appetite.

Abstract

This study aimed to determine the effect of dragon fruit peel extract on the motility and abnormalities of native chicken spermatozoa. The study was arranged experimentally using a completely randomized design consisting of 4 treatments and 3 replications. Before treatment, 12 native chicken were randomly divided into groups and adapted for 10 days with commercial feed and drinking water. The treatments were given orally for 8 weeks and consisted of P0 (control), P1 (1 ml dragon fruit peel extract), P2 (3 ml dragon fruit peel extract), and P3 (5 ml dragon fruit peel extract). Cement storage is carried out by the sequencing method. The quality of the collected sperm is tested in the laboratory. The parameters measured were microscopic sperm quality, namely sperm motility, and abnormalities. The results showed that dragon fruit peel extract had a significant effect on spermatozoa motility by increasing the percentage of motility but had no effect on spermatozoa abnormalities. Provision supplement of 5 ml dragon fruit peel extract gave the best results in increasing spermatozoa motility in native chickens.
