Abstract

This study aims to determine Heritability value of F1line of black rice characters result from pedigree selection. This research conducted by field experiment carried out at the research station of Faculty of Agriculture, University of Mataram. Nyur Lembang Village, Narmada District, West Lombok Regency, NTB Province from February to June 2018. This research empioyed Randomized Complete Blok Desing (RCBD) by 40 genotipes as treatments with replications, so there are 80 of experimental units. Observed data analized by analysis of variance (ANOVA). The result of research showed that high of heritability value gained from flowering age plant height, panicle length, number of grains filled, and weight of 100 grains. Low heritability criteria are shown by number of productive tillers, number of empty grains, weight of grains per clumpsand yield (ton.ha-1)

Abstract

Plant rhizosphere has various types of microorganisms, including Arbuscular Mycorrhizae Fungi (AMF). Each ecosystem has different species and densities of AMF. For further use, study the potency of indigenous AMF is necessary. This research was conducted to know the existence and potency of indigenous AMF of soil where physic nuts grow on dry land of Palu Valley at Poboya, Palu, Central Sulawesi. Soil samples were collected, and then observed under microscope. The steps to study the potency of AMF were counting the propagules with Most Probable Number (MPN) method, spora trapping, identifying the types of spore, and single spore culture. The result showed that the number of infective AMF propagules from cultivated soil was 1117 microorganisms/g soil and from of natural soil was 711 microorganisms/g soil; and indigenous AMF from the soil where physic nut grown at Lembah Palu were dominated by Glomus sp.

Abstract

Lettuce and Moringa are recently popular vegetable crops because their demand improves significantly, and their development lead to dry land because its potencial in Indonesia is still high.  The use of dry land should be followed by applying inter cropping technique in order to make plant micro climate becomes more favourable. In addition, low soil fertility and intensive ussage of inorganic fertilizers makes the application of organic fertilizers imperative. The objective of the research is to investigate the type of organic fertilizer giving high yield of lettuce and moringa cultivated using inter cropping technique in dry land. The results showed that the organic fertilizers applied improved the plant growth and yield, and also improved the land equivalent ratio (LER).  The highest LER was showed by apllication of Organox, followed by  Bio Extrim and Biota Plus, and the lowest one showed by without organic fertilizer application.

Abstract

The presence of microbial communities in the digestive tract affects the physiological functions of digestion. The purpose of this study is to determine the bacterial community in the digestive tract of lobsters, especially pearl lobsters. This research is descriptive explorative. Samples were taken from the lobster digestive tract which was divided into 3, namely the cardiac, pylorus and intestinal sections and each part was counted for the total bacteria using the TPC (Total Plate Count) method. Then isolated from the Sea Water Complex media and partially characterized. The results showed that the total number of bacterial cells in cardiac, piloric and intestinal cells were 41.91 x 108 cfu.ml-1, 18.26 x 108 cfu.ml-1 and 14.10 x 108 cfu.ml-1 respectively. The number of bacterial isolates obtained from the lobster pearl digestive tract were 51 isolates with details of 18 cardiac isolates, 16 isolates in piloric, and 17 isolates in the intestine. Phenotypic isolates obtained from lobster digestive tract bacteria consisted of monococcus 37.25%, diplococcus 27.45%, streptococcus 29.41%, staphylococcus 1.96%, and long baccil 3.92%, while gram positive 62.65 % and gram negative at 37.25%

Abstract

troke is a leading cause of mortality and morbidity in Indonesia.  Post stroke patients has a higher disability hence results in poor quality of life compared with normal population. In Indonesia, studies related to the quality of life of post-stroke patients are scarce, so studies are required to explore the quality of life of post-stroke patients, particularly in West Nusa Tenggara. Aim of this study is to determine the epidemiology of quality of life for post-stroke patients in West Nusa Tenggara. Methods of this study is An Observational with cross-sectional design was performed in population of post-stroke patients admitted to West Nusa Tenggara General Hospital. The quality of life of post stroke patient was evaluated with SSQOL (Stroke Specific Quality of Life) questionnaire. The collected data was analyzed by the appropriate test. Result of this study is the average age of subject is 60.33±10.68 years. Hypertension is a major risk factor of stroke. The average SSQOL score is 177.02±45.75. SSQOL assesses 4 dimension are physical, functional, psychological and social health. Based on the physical dimension, the average score is 17.00, the functional dimension, the average score is 14.91, the psychological dimension, the average score is 13.17 and the social health dimension  the average score is 13.44.  The quality of life for post-stroke patients in West Nusa Tenggara General Hospital is good.

Abstract

his study specifically aims to study the effectiveness of Moringa oleifera L. Moringa oleifera seed powder as a biocoagulant and disinfectant for river water treatment. This study use a factorial randomized block design (RBD) with four replications. The treatment in this study consisted of 2 factors, the variation factor of biocoagulants (v) and the biooagulants concentration (k). Moringa seed variation factor consists of 2 levels, namely Moringa seed powder (v1) and Moringa seed pulp (v2) powder, the factor of Moringa seed powder concentration and Moringa seed pulp powder consists of 3 levels, namely 0.025% (k1), 0.05 % (k2) and 0.075% (k3). Analysis carried out on river water, treated water and water after screening included pH, color, turbidity, manganese (Mn), iron (Fe) and total coli bacteria. The best quality processed water is treated with Moringa (v1) seed powder with a concentration of 0.05% (k2) with the following characteristics: pH 7.21, color 11.25 TCU (True Color Units), turbidity 2.38 NTU (Nephelometric Turbidity Units), manganese (Mn) levels 0.022 mg.L-1, iron content 0.036 mg.L-1, and coli bacteria total 0.08 x 102/100 ml samples

Abstract

TA descriptive research aimed to identify the characteristics and name of main soils in Lombok Island was carried out through field observation for soil profiles and landform and laboratory analyses for soil physical and chemical properties. The type or name of soil was defined by using The National (Indonesian) Soil Classification System (2014), Soil Taxonomy (SSS-USDA, 2014), and World Soil Reference (FAO, 2014). There were 4 main types of soil in Lombok Island, which were Litosol, Aluvial, Kambisol, and Vertisol; and a fairly developed soil in limited spots was Mediteran. Based on the soil taxonomy system, those soils were respectively equivalent to Orthents, Fluvents, Undepts, Underts, and Udalfs; whereas based on the soil system of FAO, were Leptisols, Fluvisols, Cambisols, Vertisols, and Luvisols. The main characteristics of Litosol/Orthents/Leptosols Lombok were shallow solum (< 25 cm on the rocks or lithic contacts), coarse textured (sandy), nutritionally deficient, very low CEC (< 5 cmolc.kg-) and C-organic content (< 1 %). Aluvial or Fluvents, were mainly utilized as paddy soil, consisting of several layers which it clay and C-organic content were changed irregularly with depth, CEC of top soil (Ap) was medium (5–10 cmolc.kg-), and it was relatively fertile. Kambisols or Undepts was fairly deep (consisting of 40 – 60 cm of A and B horizons,), loamy textured, fairly fertile, CEC was medium, and C-organic content was low – medium (1–2 %). Vertisol or Uderts was characterized by a significant swell-shrinking properties, clay textured, extremely hard to be cultivated, high CEC, Ca, and Mg, and relatively fertile soil. Mediteran or Udalf was a further developed soil (solum > 100 cm), clay translocation has been occurred from upper (E) to lower horizons (Bt), CEC was fair, and it was relatively fertile soil. In conclusion, the pedologic development of soils in Lombok Island was relatively slow due mainly to the low–moderate rainfall, and the soil types were dominated by Litosols, Aluvials, Kambisols, and Vertisols, and Mediteran in small area. In order to provide a complete reference for the characteristics of main soils in Lombok Island, it necessaries to define mineralogy composition through X-ray diffraction analysis (XRD) and thermogravimetry analysis (TGA) of the clay fractions of the soils
