Water used for drinking is healthy water that must meet the requirements of Bacteriology, based Kepmenkes RI No: 907 / Menkes / SK / VII / 2002 concerning the terms and monitoring the quality of drinking water, where for the value of the Most Probable Number (MPN) is 0 / 100 ml water samples were analyzed. In the method of testing microbiological quality of drinking water is used as an indicator Coliform group. The purpose of this study was to detect the presence of Coliform bacteria in water samples tested wells. Samples were tested in the form of water wells located in the Village RT.V Padang Jati. Research Well Water Quality Test Method Using MPN (Most Probable Numbers) was conducted in March 2014. This study uses observation deskription is through direct observation to determine the possibility of Coliform bacteria and fecal Coli. Data based on observations or surveys taken directly to the location you made to sample, as well as the examination of samples directly in the laboratory to obtain primary data. Results or Coliform MPN index and fecal Coli were compared using the formula 555 Thomas MPN table. The results showed that all samples test positive for Coliform bacteria, so it is not fit for use as drinking water.

Most of the area of South Sumatra Province covering an area of 87,017 km2 is peatland spread across the eastern region, starting from Musirawas, Muba, OKI, Muara Enim, and Banyuasin regencies. most of it is swamp land or about 1.42 million ha is peat land. Rice is the main food crop cultivated in Indonesia. One of the problems that are often encountered in the field that greatly affects rice productivity is weeds. Weeds are nuisance plants that grow around cultivated plants. This is the background for the creation of weed control innovations, namely by using Organic Planting Tape (OPT) as a rice planting medium. This study aims to determine the effect of OPT as an inhibitor of weed growth and determine the optimal width and thickness to inhibit weed growth. The experiment was arranged in a Randomized Block Design (RBD) with 3 groups and 5 treatments. Group I OPT width 20 cm, group II 30 cm, and group III 40 cm. While 1 was control (without OPT), treatment 2 was 4 mm thick, treatment 3 was 6 mm thick, and treatment 4 was 8 mm thick. This research was conducted from July to August 2019 in Mukti Jaya Village, Muara Telang District, Banyuasin Regency. carried out for 40 days. Observation of data obtained by analysis of variance or F test at 5% level. The results showed that the width and thickness of OPT had an effect on decreasing the number of weeds and weeds. OPT 40 cm wide and 8 mm thick did not produce the number of weeds that grew. The bigger and thicker the OPT, the more effective it is to deal with weeds.

AbstractPagaralam is one of the tomato suppliers for the South Sumatera region. Tomatoes are often attacked by pests such as aphids. Aphids fleas (Aphid sp.) are one of the main pests besides that aphids are important vectors that can transmit viral disease. The use of chemical insecticides can damage agricultural land for the use of vegetable insecticide alternatives. Alkoloid, Flavoid, Saponin, and Tanin contained in papaya leaves (Carica papaya) can be used as a plant aphid insecticide. The sample in this study was a 2 month old tomato plant with 20 aphids in each tree. Treatment was given to 5 treatment with 5 replications. This treatment by giving different concentrations of papaya leaf solution in the crop of 0%, 15%, 30%, 45%, and 60%. To determine the effectiveness of papaya leaf solution (Carica papaya) as a vegetable insecticide aphid done spraying as much as 100 ml once spray with contact time observation 12 hours and 48 hours. The results showed that the application of papaya leaf juice was effective in killing aphids, so that high concentrations that gave greater precentage of aphids deaths ranged from 24 hours showed F count > and F table and received at level 1% means that papaya leaf juice was very influential on aphids death. Then the results of cofactor coefficient (KK) 24 hours and 48 hours were 10% and 4%, before using The Smallest Significant Difference Test (BNT) to see the effect of each concentration. BNT Test pre view, each concentration was very significant which had a different effect on the death of ticks to analyze probit LC50 to determine the effective concentration of killing 50% of the samples at 39,81%. This is related to every usage given such as concentration and monitoring time. Keywords: Papaya Leaf (Carica papaya); Papaya Leaf Solution Concentration; Fleas (Aphid sp.)

Humans need water for various purposes, such as bathing, cooking and most importantly for everydayconsumption. Along with today's technological advances and accompanied by increasingly busy human activitythen people tend to choose a more practical way with relatively low cost to meet the needs of drinking water byusing drinking water contents ulang.Permenkes No. 429 in 2010, assessed quality drinking water frommicrobiological parameters are not the discovery of total coliform bacteria in 10 ml of sample. According tosome previous studies, many refill drinking water depot that produce water does not comply with themicrobiological peryaratan. The purpose of this study is to conduct a microbiological water qualitypresentation based on the value of MPN Coliform, by identifying the presence of Escherichia coli in drinkingwater produced depot refill drinking water around the UIN Raden Fatah Palembang. The study was conductedin June 2016 in the Laboratory of the Faculty of Mathematics and Teaching Tarbiyah Raden Fatah StateIslamic University in Palembang. This study uses qualitative descriptive method by comparing the laboratoryresults with standard tables Most Probable Number (MPN), which consists of a test estimation, confirmationtest, and test the amplifier. Get their research results in the bacteria Escherichia coli and Coliform. Of the foursamples unfit for consumption because of a fourth consecutive MPN values per 10 ml coliform bacteria are12.4 per 100 ml; 22.7 per 100 ml; 14 per 100 ml; 1100 per 100 ml, and contains the bacteria Escherichia colisequentially 12.4 per 100 ml; 22.7 per 100 ml; 3 per 100 ml; 1100 per 100 ml.

The aims of this research is to know the effect of liquid wastes on vegetative growth of red spinach plants. This research used Factorial Random Design (RAL). Objeks in this research are nutrient solution (L) and planting medium (M). The data was analyzed using two way ANOVA. The treatment in this research is nutrient solution (L) and planting medium (M). There are 2 types of nutrients used, the aquadest and the tofu liquid waste. There are 2 types of medium used, the cocopeat media and sand media. From result of research it is known that, at treatment L1M1 which is treatment with tofu liquid waste on cocopeat planting medium technique obtained high yield of planting with average 7,70 cm. Likewise on the observation of the number of leaves on L1M1 treatment also obtained an average yield of 4.00 pieces. Similarly, at the roots of red spinach plants obtained the highest average, namely the treatment of L1M1 with an average root length of 23.75 cm. Conclusion the use of tofu liquid waste as an additional nutrient for the growth of red spinach vegetable plants has an effect on the vegetative growth of red spinach plants.

Paper generally uses wood as the main raw material, which is increasingly expensive, so it requires alternative raw materials such as rice husks. Banyasin Regency is a food producer and provides high by-products (rice husks), so the researchers aim to use rice husks into paper. The method used in this study includes display data (presentation of data) the results of the utilization of rice husks, and the conclusion (conclusion) of the resulting paper. The results obtained from the use of rice husk into paper in assisting the community of the Muara Telang District, Banyasin Regency, received positive responses from the community, which was indicated by the attitude of the residents in managing the husks into paper and the paper produced had characteristics, was bright brown in color, flexible, and had a husk motif. The paper obtained from this activity is suitable to be developed as a calligraphy and other craft materials.
