Abstract

The increase of energy needs coupled with the decline in fossil fuel production, requires other sources of energy to meet those needs. One of the solution is using renewable energy. Bioethanol is one of the alternatives to the fossil fuel. This study was aimed at determining the exact mass of mango seeds in producing high grade bioethanol. Bioethanol was produced by fermentation of arum manis mango fruit seed using bakers yeast, Sacczharomyces cerevisiae.  The arum manis mango seeds were known to contain carbohydrate contents of 19.53%. The study was conducted by using different mass of mango seeds 25, 35 and 45 g resectively. The study showed that the samples of 25, 35 and 45 g produce ethanol with concentration of 4.78, 6.64 and 1.48%. These results indicated that the mass of 35 g mango seeds produced highest ethanol content.

Abstract

Physiological stress due to nutritional deficiency accompanied by excessive activity can cause problems of energy deficiency required by the body. Energy shortage can affect the body weight, as well as the weight and histology of the liver. This study was conducted to examine and analyze the effect of snakehead fish meat supplementation in feed toward body weight, weight and hepatic histology in animals experiencing physiological stress. This study used 20 male Wistar rats consisting of 5 treatments with 4 replications. The treatment in this study consisted of control (P0) and treatment (P1: 5%, P2: 10%, P3: 15%, P4: 20%) groups. This research used Completely Randomized Design (RAL). The variables measured in this study were body weight, hepatic weight, central venous diameter and hepatocytes in the test animals. The data obtained were analyzed using Analysis of Variance (ANOVA) at 5% significance level and continued with Duncan test with 5% significance. The result of data analysis showed that fish snakehead fish supplementation in feed gave a significant effect to body weight, weight and histology of animal liver. Concentrations of snakehead fish supplements can increase the body weight, hepatic weight, and hepatic histology which was indicated by higher central venous and hepatocyte diameter values compared to other controls and treatments. The conclusion of this research is the provision of snakehead fish supplement (Channia striata) can increase the body weight, hepatic weight, central venous and hepatocytes diameter of Wistar rats with the most influential concentration of 20%. This evidence is useful in studying the mechanism of liver repair due to stress

Abstract

Anthrax is a deadly disease caused by Bacillus antracis that damages the lymphatic and vascular systems of animals and humans. Anthrax prevention in Indonesia has been done but has many shortcomings among them is a lot of dead animal raises after vaccination and relatively expensive. The azadirachtin bioactive compound produced by neem endophytic microbes is known to inhibit the growth of B. anthracis bacteria, thus potentially as an anti-anthrax agent. Other bacteria that have the same pathogens as B. antrachis are Methycillin Resistant Staphylococcus aureus (MRSA) so that it is used as a research object. The aim of this research is to obtain the active biomaterials from selected neem leaf endophytes to be tested in S. aureus MRSA as bacteria with Anthrax pathogens. The method used in this research is the isolation, selection, and extraction of Neem  endophytes. The process of isolation is done by growing on the general media and the selection process on special media. The bioactive extraction process uses 1000 rpm centrifuge and screening on MRSA culture medium. Inhibitory zone tests were used to determine the effect of endophytic biopsy in inhibiting MRSA growth. The result of the research is that the bioactive endophytes of neem are able to inhibit MRSA growth which is characterized by the formation of drag zone around the endophytic bioactive. Thus it can be concluded that the use of neem endophytes can be a new solution to eradicate the presence of anthrax disease in the livestock and people in Indonesia with safe research methods, relatively inexpensive and ineffective vaccine replacements.

Abstract

Serat dalam beton berfungsi mencegah retak-retak sehingga menjadikan beton lebih kuat daripada beton tanpa serat. Kawat galvanis banyak digunakan karena murah, mudah dibentuk dan mudah perawatannya. Tujuan penelitian untuk mendapatkan material serat buatan yang relatif murah dan mampu meningkatkan kekuatan beton secara optimal ditinjau dari kuat tarik dan kuat lentur. Material agregat halus yang digunakan dalam penelitian ini adalah material lokal pasir Samboja. Jenis Serat yang digunakan berupa serat buatan kawat galvanis berbentuk linting, spiral dan crimped. Hasil penelitian menunjukan bahwa benda uji BC1 (Crimped Ñ„ 1cm) memiliki kekuatan tarik terbesar dan L5 (Linting 5) memiliki kekuatan lentur terbesar dibandingkan benda uji lainnya. Besarnya kuat tarik yaitu 10,44 MPa dan kuat lentur sebesar 7,03 MPa.

Abstract

Physiological stress for a long time can lead to impaired kidney organ function. Snakehead fish meat are known to contain important nutrients such as albumin, glutamine, glycine, cysteine, and various minerals that can improve kidney function. This study was conducted to examine and analyze the effect of snakehead fish supplementation in feed towards body weight, kidney weight, diameter and number of glomerulus in Wistar rats with physiological stress. This study used 20 male Wistar rats divided into 5 groups consisted of 1 control group (P0) and 4 treatment groups (P1: 5%, P2: 10%, P3: 15%, P4: 20%). The treatments were performed with 4 times repetition. This study used Completely Randomized Design (CRD). The variables measured were body weight, kidney weight, diameter and number of renal glomerulus. The data obtained were analyzed using Analysis of Variance (ANOVA) at 5% significance level and continued with Duncan test with 5% significance level. The results of this study were: the supplementation of snakehead fish with 20% of concentration can increase the body weight; concentration 10; 15; and 20% can increase the weight of the kidney; concentrations of 5%, 10%, 15%, and 20% can increase the glomerular diameter in Wistar rats with physiological stress. The supplementation of snakehead fish with concentration of 5% to 20% did not affect the number of glomerulus of Wistar rats with physiological stress. Results of this study is useful as information for people who study the mechanism of kidney repair due to physiological stress.
