Abstract

Staphylococcus aureus is the normal microflora of the human body. These bacteria can turn into pathogens from migrating to other areas of the body, the wounds and lower the bodys immune system causes ulcers, blood clots and other. One way to overcome this is by using pulai leaf. The porfuse research is to determine the bioactive material and antibacterial compounds contained in the pulai leaves bioaktifitasnya tested against S. aureus bacteria. Experimental research has been conducted on the antibacterial compound isolation process is done in a way: using Soxhlet extraction, fractionation using vacuum liquid chromatography, and purification by column chromatography gravity. Antibacterial bioactivity testing performed by the agar diffusion method. The results showed that the pulai leaves have antibacterial ability against S. aureus. The most active extract is methanol. Active fraction contained in the pulai leaves  belonged phenolic compounds. Keywords: antibacterial bioactivity, extract, fractions, pulai leaves, Staphylococcus aureus.

Abstract

This paper reports the results of the study on the peat swamp in the Kedaton Village as Silvofishery. Research was conducted between May  till October 2012. This research was carried out  using survey method. Sample was taken by purpossive sampling. Data and information gathered included diversity index  of vegetation, selected soil and water quality, plankton, macrozoobenthos, water insect and fish. Results of the study get 2 species of vegetation in tree, 4 genera of plankton, 3 genera of macrozoobenthos, 2 species of insect water and 3 species of fish. That peat swamp in the Kedaton Village have potency as Silvofishery, although diversity index of vegetation and plankton was median chategory,  and diversity index of macrozoobenthos, insect water and fish was low chategory.Key words : peat swamp, vegetation, plankton, macrozoobenthos, fish

Abstract

Research on weed vegetation analysis at watermelon plantation was carried out from September to November 2014 in the village of Scales watermelon plantation Inderalaya District of Ogan Ilir South Sumatra Province. This study aims to determine the composition and structure of weed in watermelon plantations. This research is a survey directly to the field with vegetation analysis using squares method. The parameters observed see density (K), relative density (KR), Frequency (F), Relative frequencies are (FR), Importance Value Index (IVI) and the Diversity Index. Results of this study, the 9 types of weeds are Echinochloa colonum, Cynodon dactylon, Axonopus compressus, Eleusine indica, Cyperus rotundus, Asystasia coromandeliana, Cleome rutidosperma, Emilia sonchifolia and Ageratum conyzoides. The species is dominated Cyperus rotundus IVI 37.546%. Diversity of species classified as being at H’ value of 2.1. Key words : Analysis of vegetation, weeds, watermelon

Abstract

Research on the effect of compound fertilizer on plant growth celery (Apium graveolens L.) has been implemented in October 2014 - February 2015, in plantations 16 Ulu Village, District Seberang Ulu II Palembang. This study aimed to determine the effect of compound fertilizers to celery plant growth and to determine at what dose the average total folium and plant fresh weight. The method used was completely randomized design (CRD), consists of six treatments and four replications. The dose used is A0 (without control), A1 (0.5 grams), A2 (1 gram), A3 (1.5 grams), A4 (2 grams), A5 (2.5 grams). Research results showed that administration of different doses significantly affect of total folium and celery plant fresh weight. The higher the dose applied, the better the plant growth. Best doses indicated in the treatment of A5 (2.5 g), which gives the average total folium 3 (strands) and wet weight of 1.7 grams. Key words: Compound Fertilizer, Apium graveolens L. Growth

Abstract

Research on Chromium Analysis Total Regional Industrial Weaving Songket Palembang Musi River has been carried out in July and August 2013. This study aims to determine the concentration of total chromium (Cr-T) in the three sampling sites were in the vicinity of the domestic weaving industry songket Palembang Musi River. the results obtained by the average concentration of total chromium (Cr-T) at three sampling locations at 0.8094 mg / L and an average pH of the third water sampling locations ranging from 6.8. Based on South Sumatra Governor Regulation No. 18 In 2012, the average concentration of total chromium at three sampling locations are around the area songket Palembang Musi River is still below the standard that is below 1 mg / L. Keywords: chrome total, songket weaving industry, The Musi River
