Abstract

Fish as a source of animal protein has several advantages over other animal protein sources, one source of animal protein that is Dumbo catfish. Dumbo catfish fish including fish which is most easily accepted by society. This study aimed to determine the effect of feeding on African catfish (Clarias gariepinus) using chicken intestine and tofu on the growth of catfish. This study was conducted on August 24, 2015 until 24 September 2015. The parameters observed in this study were weight and length. The study was conducted using a randomized block design (RAK) with 4 treatments and 4 groups: feeding by comparing the administration of fish feed manufactured in the form of pellets 100% (control), feed chicken intestines 100%, the feed pulp out of 100%, and chicken intestine feed pulp 50% + 50% Fish test with a weight of 20 grams and 12 cm. With other factors such as pH and temperature equated water. Feeding 2 times a day for 30 days of maintenance. The results showed that there was significant difference between the treatment given to the growth of the weight and length of catfish, feed A1 (chicken intestine 100%) gave the best growth of the African catfish and significantly different from other treatments (P <0.05). Absolute growth of 39.1 grams with a length of 31,2 cm

Abstract

Fish is one of the animal protein sources consumed by people because it is relatively easy to obtain and affordable. The abundant of the fish needs some ways to preserve it, one of them is by making bekasam. Bekasam is fish fermented product which is procesed with the addition of rice and salt. One of the function of the salt is to select microorganisms that produce proteolytic enzymes.The purpose ofthis study was to know influance of different salt concentrations to ward the quality of fish bekasam.The research was conducted in August 2015 in Chemistry Laboratory of Biology Education Study Program, Teaching Training and Tarbiyah Faculty UIN Raden Fatah Palembang. The research method was an experimental laboratoryusing a CRD with 4 treatments and 3 replication. The treatments were salt concentrationK0 (10% b/v), K1 (20% b/v), K2 (30% b/v) and K3 (40% b/v). The test parameters observed were theacidity and hedonic test (color, smell and taste). The parametric data for the acidity was analyzed by ANOVA test, while nonparametric data(hedonic) used the organoleptic test. The results showed that based on ANOVA, the different salt concentration gave a very significant different influance (P=0,01) toward the acidity value, that Fcount> Ftable is 26,16 > 7,59. Based on research result, the acidity of each K0, K1, K2and K3 was 1,13 N, 1,00 N, 1,02 Nand  0,42N.Treatment of 10% salt concentration resulted the highest  acidity 1,13 N.While from hedonic test showed that bekasam with 20%salt concentration was the most preferred

Abstract

Aedes aegypti mosquito, which acts as a vector in the spread of dengue disease. One of the effort to reduce thespread of dengue disease is using larvicides. Brotowali thought to have an effect as larvicides against Aedesaegypti larvae because they have the alkaloid compounds and tinokrisposid that can cause death in larvae. Thisstudy aims to determine the effect extract brotowali (Tinospora crispa) against Aedes aegypti larvae of death soas to provide information to the public that can be used as larvicidal brotowali. This research is an experimentwith a completely randomized design (CRD) with 4 treatments and 6 replicates. The samples used were thirdinstar larvae of Aedes aegypti with the treatment A0 (abate 500 ppm), A1 (500 ppm), A2 (750 ppm), and A3(1000 ppm). Observations dead larvae were carried out for 24 hours and 48 hours. The results showed thatwithin 24 hours at a concentration of 500 ppm on average larvae death reached 32.5%, the concentration of 750ppm 55.8%, a concentration of 1000 ppm to 70%, whereas within 48 hours at a concentration of 500 ppm onaverage larvae death reached 75%, 90.8% concentration of 750 ppm, a concentration of 1000 ppm to 100%.Based on analysis of variance (Ansira) showed that the extract brotowali (Tinospora crispa) gives a significantinfluence (p > 0.01) in the death of larvae of Aedes aegyti. Effective concentration to kill larvae of Aedes aegytinamely the concentration of 750 ppm.

Abstract

The issue of environmental pollution has become a concern, especially for the government, since the establishment of Law No. 4 of 1982. This is because the effects of pollution can be toxic and even fatal for living beings, particularly humans. One of the pollutants in the environment generated from mining industry waste is heavy metal Fe. In light of these problems, a study was conducted to investigate the effectiveness of sawdust and Moringa twigs as by-products in adsorbing heavy metal iron (Fe) in the liquid waste of the gold mining industry. This research is classified as pure experimental research. The research reveals that the mean percentage reduction in the heavy metal iron (Fe) content in the gold mining industry wastewater, after treatment with the addition of Moringa leaf powder, is 9.6%. On the other hand, treatment with the addition of Moringa stem powder achieves a reduction of 92%. This significant difference is attributed to the bioactive compound rhamnosyloxy-benzyl isothiocyanate present in Moringa. This compound has the ability to adsorb and neutralize sludge and metal particles found in the waste suspension, along with dirt particles in the water. Consequently, Moringa shows potential as a natural coagulant for water purification purposes.
