Abstract

Aims of this study to concentration test of methane gas from swamp forage silage with in vitro methods.This study used Completely Randomized Design with 3 treatments and each treatment consisted of 5 replications. The treatments used are as follows: P1 (100% kumpai tembaga grass (Hymenachne acutigluma)), P2 (50% kumpai tembaga grass (Hymenachne acutigluma) + 50% kemon air (Neptunia oleracea lour)), P3 (100% kemon air ( Neptunia oleracea lour)). The parameters observed N-Ammonia, total gas production, methane gas concentrations in vitro and VFA partially. The results of variance showed that treatment significantly different (P <0.05) with methane concentration  in vitro with highest gas concentration treatment of silage made from 50%  kumpai tembaga grass (Hymenachne acutigluma) and  50% kemon air (Neptunia oleracea lour).Keywords: Concentration, Methane, Silage Forage Swamp, In Vitro.

Abstract

The study was conducted to determine the effect of land typology and lime on the population of indigenous nitrogen-fixing bacteria and soil pH, and to analyze the effect of soil typology interaction and lime on the population of indigenous nitrogen-fixing bacteria and soil pH. Sampling of soil in tidal land of Mulya Sari and Banyu Urip Village of Banyuasin Regency, South Sumatera. Then the sample was studied at the Laboratory of Microbiology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Sriwijaya, Inderalaya. During January-May 2017. Based on the results of the study known the soil typology of the total population of nitrogen-fixing bacteria, the highest population of nitrogen inhibitor bacteria in the second week of soil typology D was 6.0x107 and the highest pH of 5.18 in typology B on week Third, the lime treatment that affected the population of indigenous nitrogen-fixing bacteria, obtained the population of bacteria as much as 9.3x105 in the second week and the highest soil pH 4.93 in the second week, while the results of the interaction between soil typology and lime treatment only affect the population of bacterial inhibitor Indigenous nitrogen, with bacterial population of 3.5x107 in soil typology D in the second week, but this interaction did not significantly affect soil pH, with the highest pH measurement of 5.33 on the soil typology D.Keywords: nitrogen-fixing bacteria, tidal land, lime treatment

Abstract

The research entitled “ Study on Macrozoobenthos Community in the Waters of the River Air Perikan Pagar Alam Municipality”, was conducted from November 2007 until March 2008. The aims of the research: to know about composition, density, diversity index, dominancy index, and similarity index, which based on the different microhabitat types. Sampling was carried out on November 2007. Five sampling stations were determined by survey method  and the Purposive Sampling method was used at each sampling point to find stony, gravel, sandy and leaf pack area as a different microhabitat substrate. Twenty one orders (Ephemeroptera, Trichoptera, Diptera, Plecoptera, Collembola, Hemiptera, Odonata, Coleoptera, Lepidoptera, Megaloptera, Hymenoptera, Orthoptera, Decapoda, Plesiopora, Tricladida, Amphipoda, Isopoda, Mesogastropoda, Ctenobranchiata, Eulamellibranchiata, and Rhynchobdellida) which are consisted of 70 families and 151 genera were identified from four types of substrates on each sampling station. According to this research, station 4 has the highest in composition (80 genera), and the lowest one at station 1(33 genera). The highest abundance was 12589 ind./m2  found in the station 5, and the lowest one was in the station 1 approximately 880 ind./m2. For the diversity index value, station 3 was the highest (3.1) and the lowest one was station 5 (1.9). The Dominancy index was found in station 5 at the sandy substrates was  approximately 0,8 index, which dominated by Tubifex sp. There were  differences species composition  on each station. Keywords : Macrozoobenthos, community, the river Air Perikan.

Abstract

Despite high attention and commitment of Indonesia in biodiversity conservation and its habitat, however, loss of biodiversity and habitat deforestation is also still high. Deforestation rate in Indonesia between period of 2000-2012 reach up 6.02 million ha, and approximately onethird of which is in Sumatra Island. As the fulfillment of CBD and Aichi targets, and in line with the mandate of the Law on the Conservation of Natural Resources and Ecosystems and IBSAP (Indonesian Biodiversity Strategy & Action Plan 2015-2020), we try to support the requires data as well as information on the current state of biodiversity. The aims are to develop an inventory system of biodiversity needed to establish baseline data on biodiversity including its conservation status in South Sumatra, develop a biodiversity monitoring system with qualitative parameters that can be used in the determination and monitoring of degradation rates of biodiversity, and the establishment of data management system and information network of fauna biodiversity in South Sumatera so that it can be utilized in monitoring and reporting of biodiversity at regional, national and international level at the international level. We conduct a comprehensive review of methods and techniques of inventory and monitoring of fauna biodiversity, especially those that have been done in the area of South Sumatra Province. We also analysis of data needs and information network of fauna biodiversity in South Sumatra. The results is shows in the web-application database, called the South Sumatran Biodiversity Information Networks, or SSBIN, and could preview at http://ssbin.unsri.ac.id/.Keywords: south sumatra, biodiversity, information, networks, SSBIN.

Abstract

The Research about the food habits and length-weight relationship of Labiobarbus leptocheilus Valenciennes was conducted from May to September 2010. The aims of this research were to find out the food habits and to analyze the growth pattern of Labiobarbus leptocheilus Valenciennes. The sampling of fishes was conducted on May 2010 in the Gajah Mungkur Reservoir, Central Java. The sampling of fishes was conducted by using survey on the landing place of fishes (TPI Mina Tirta). The methods of analysis of food habits by using the Index of preponderance. The results of this research obtained were 19 samples of Labiobarbus leptocheilus Valenciennes, the length between 15-20 cm, with the weight between 40-90 grams. Labiobarbus leptocheilus Valenciennes had the negative allometric growth pattern (b <3). The laboratory analysis of food habits showed that the food habits of Labiobarbus leptocheilus Valenciennes were detritus with Index of Preponderance (IP) 82.95% and plankton with IP 17.05%.Keywords: food, habits, length-weight, relationship, Labiobarbus leptocheilus

Abstract

Besemah tribe uses plants in addition to the treatment is also used for beauty treatments traditionally. Based on Agustina's (2015) study, 109 species of plants were used for traditional medicine by the Tribe of Besemah. Some species of Lamiaceae for traditional medicine such as patchouli (Pogostemon cablin (Blanco) Benth.), wild mint (Mentha arvensis L.), hoary basil (Ocimum americanum L.), mexican mint (Plectranthus amboinicus (Lour.) Spreng.), and sweet basil (Ocimum basilicum L.) contains essential oils that can be used for traditional cosmetic ingredients. Essential oils are stored in the secretory structure of plants in leaf and stem organs. This study aims to determine the type and location of the secretory structure of essential oils in some species of lamiaceae used for traditional cosmetics of Besemah Tribes Lahat’s District. The research was conducted in November 2016 until February 2017. The results showed that patchouli plants was found in the presence of glandular trichomes, oil cells, and idioblast cells. The wild mint plants have glandular trichomes. The hoary basil plants have glandular trichomes and oil cells. The mexican mint plants have glandular trichomes and idioblast cells. The sweet basil plants have glandulartrichomes.Keywords: essential oils, lamiaceae, traditional cosmetics, Besemah tribes,  glandular trichomes, oil cells, idioblast cells
