The growth of fungi can be influenced by nutrients is in the environment, With the additional two kinds of nutrients from sugar plant waste of molasses, and waste of the pepaya taken the filtrate. Both of these wastes contain sugar which is needed by fungal microorganisms to grow and reproduce. The fungus Aspergillus niger, Hansenulla sp, Trichoderma viride, and Candida sp have a synergy interaction in a media. This study aims to learn in the growth of fungal cell populations as cell masses in potato dextrose media with the addition of two kinds of nutrients. The method used in this study was a two-population mean test with 2 treatments, namely the first treatment with the addition of sugarcane drops, and the next with the addition of papaya fruit filtrate, consisting of 11 replications, with incubation for 3 days. The analysis used was the T test and the analysis results obtained were significant, which was shown from P> 0.05. The mass of fungi cells in the addition of nutrients...

Biogas is gas that produced by anaerobic activities or fermentation result from organic matter including dirt human and animal, domestic waste (households), biodegradable garbage or any biodegradable organic waste in anaerobic condition.  Bio-slurry or biogas waste is a product of biogas processing that made from a mixture of livestock manure and water through anaerobic fermentation processes in biogas installations. This research was carried out to get the dominance value of microorganism colonies at the quantity of nitrogen and sulphur which the result of mineralization in the biogas fermentation residue, to determine the concentration of NH4+ ( % ) and sulphate ( % ) as the quantity of nitrogen and sulfur by mineralization result at the residue of the biogas fermentation process. This research was usesd method of descriptive – quantitave and SPC analysis. A value of diversity index ( H’ ) of 0.98352 and domination value (D ) of 0.10476. Microbial dominaton was  obtained 31 white ...

The research aims is to examine the quality of refill drinking water around UNISMA campus, it is reviewed about the test of physical, chemical and microbiological quality, and to know whether the quality of drinking water is in compliance with quality standard of drinking water No.492/MENKES/PER/1V/2010. Using method of qualitative descriptive is the parameter of smell and taste. Quantitative descriptive parameters are temperature and turbidity, TDS, conductivity, pH, DO and coliform. Test and analysis of quantitative is done in laboratory toward the water sampling of refilled drinking water that is taken from three depots with purposive sampling. Sample is replicated three times from respective depot. Refill drinking water in around the UNISMA campus of Malang, the test of odor, taste, physical, chemical and microbiological quality; temperature, turbidity, TDS, Conductivity, pH, DO, and coliform, is qualify to be consumed by the people, because the value of each parameter has fulfi...

Tanning industry wasteis potential to pollute the environment because it is using a harmful chemical materials. One of many effort to prohibit the environmental pollution is a bioremediation using bacteria because bacteria can grow and adapt to any substrates that has a organic materials. The diversity of bacteria is important to know because the bacteria cover most large species diversity on earth and its role as bioremediation. The purpose of this research is to determine the value of the diversity index and the types of indigenous gram bacteria in waste water Leather Tanning Industry Malang. Data has been analysed results of measurements of pH, temperature, conductivity, the number of bacteria colonies, bacterial community structure diversity, evenness, richness and dominance) and the results of bacterial gram staining. The diversity of indigenous bacteria colonies that has been found are low and the value is 0,36; 1,30 and 0,015. Type of indigenous gram bacteria found are strept...

Broiler chicken is one of the poultry farms whose growth is fast, can meet the needs of meat in the community. To accelerate chicken growth, addition of Antibiotic Growth Promoter (AGP) was added to the beverage. This study aims to analyze the effect of monensin antibiotic administration on weight gain. The research method uses a Completely Randomized Design (CRD), consisting of 4 treatments and 6 replications. P0 Treatment (Control): Basal ration + Water boiled in 1 liter; P1: Basal ration + Boiled water + 0.1 gr / day Antibiotic Monensin in 1 liter of water; P2: Basal ration + Boiled water + 0.5 gr / day Antibiotic Monensin in 1 liter of water; P3: Basal ration + Boiled water + 1 gram / day Antibiotic Monensin in 1 liter of water. Data analysis used ANOVA one way variance and continued with the Least Significant Difference Test (LSD) with a confidence level of 5%. The results of the study by giving various concentrations of monensin antibiotics to broilers had significantly affect...

Rhizosfer tanaman Leguminosae banyak ditumbuhi bakteri, salah satunya adalah genus Bacillus yang merupakan Plant Growth Promoting Bacteria yang bermanfaat bagi tumbuhan, di antaranya karena kemampuannya dalam melarutkan fosfat. Tujuan penelitian ini untuk mendapatkan isolat Bacillus sp. dari rhizosfer tanaman Leguminosae yang memiliki kemampuan melarutkan fosfat. Penelitian ini dilakukan dengan melakukan isolasi bakteri, karakterisasi koloni, pewarnaan Gram, pewarnaan endospora, uji katalase, dan uji kelarutan fosfat. Metode isolasi yang digunakan dengan metode pour plate dan untuk pengujian bakteri pelarut fosfat menggunakan media Pikovskaya. Sebanyak 36 isolat Bacillus sp. berhasil diisolasi dengan berbagai karakter koloni dan karakter sel berbentuk batang, Gram positif, membentuk endospora, dan memiliki katalase positif kecuali isolat BAP2 dan BAP5 yang memiliki katalase negatif. Sebanyak lima isolat Bacillus sp. (isolast BCP 2, BCP 4, BAC 2, BCM 3, dan BAP 1) diketahui mampu mel...

Rhizosphere bacteria are soil microbes that can be isolated from the rhizosphere of strawberry plants (Fragaria sp). Rhizosphere bacteria are included in the group of antagonistic microbes which have the potential to inhibit the growth of the pathogenic fusarium sp fungi that infect plants that cause fusarium wilt in the roots of strawberry plants. This study aims to determine the diversity index of rhizosphere bacteria isolated from strawberry plants which are antagonistic to Fusarium sp. This study uses descriptive and experimental methods. The results of the analysis of the diversity of rhizosphere bacteria have a diversity index value of 1.35. This indicates that the diversity of rhizosphere bacteria isolated from the rhizosphere of strawberry plants is in the moderate category (1.0

Aquatic fertility in biofloc ponds is very dependent on the presence of plankton, an organism that lives floating in aquatic ponds and plays an important role as a source of natural food. This research aim to analyze the abundance and diversity of plankton in biofloc pools fed with probiotics. This study uses survey methods in the form of observations, measurement of water parameters, plankton sampling in biofloc ponds that have been given probiotic treatment at a dose that has been determined by the farmer at a depth of 1m biofloc pool with a diameter of 2m. The statistical analyzed used is the T test to diversity differences in plankton abundance between morning, afternoon and evening. The results obtained as many as 10 genus of phytoplankton and 26 genus of phytoplankton, namely Class 6 Cyanophyceae genus including Synechococcus, Oscilatoria, Choococcus, Spirulina, Microcystis, Scytonema. Chlorophyceae class 6 genus namely Haematococcus, Chlorella, Stigeoclonium, Calodophora, Tet...
