Abstract

Two main problems usually faced by corporation including cooperation are fund providing and allocation. KPBS as cooperation and as an economic unit also encounter these problems and has to operate efficiently to gain the profit in order to meet obligation and continuity. However, to attain these aims KPBS faces with fund financing problem and productivity of milk cows. The purpose of this research is to find out the value of financial rate ratios since 1993 – 2002, and compares the financial condition at the same period. The available data be analyzed with financial ratios in consist to Liquidity, Activity, Solvency, and Rent ability. This research show the value of KPBS’s financial performance 1993 during 2002 are: (a) Liquidity ratio, the highest value was 218,96% in 1997 and the lowest was 152,03% in 2002, this condition was still stated liquid because over to 100%; (b) Activity, 73,73 times in the supply period ratio in 2001 was highest then the other years, and the lowest was 4,85 times claim period in 1995 (c) Solvency, the highest value was 386,57% in capital ratio with permanent assets (solvable, because it’s over to 100%), and the lowest value in 1994 at the capital ratio with total assets, it was 36,64%; (d) Rent ability, 19,05% in 1993 was the highest value, and the lowest in 1995 was 0,6%. In case of milk productivity, the volume milk production decrease year by year and has an impact on KPBS financial performance which indicated by Ransum Concentrate (RC) application with protein under national RC standard, that is only 12% from 18% or 75% from 100%. With this condition KPBS should repair RC protein application, and maintaining production price. So that selling price still on breeders expectation.

Abstract

Study of the effect of organic and non-organic farming practice of rice (Oryza sativa L.) cv. Rojolele on seed physiology was carried out in Cipanas, West Java (on-farm) and in the laboratory of BSJ3 and greenhouse of RC for Biotechnology  (off-farm). Parameters were recorded particularly on seed germination percentage, water content, dormancy behavior and morphology. On-farm study results showed that germination percentage of organic seeds was higher (88.3% at water content of 13.4%) than those non-organic seeds (20.0% at water content of 10.2%). Results of off-farm study showed that the plant height of those organic seeds was higher than those non-organic seeds. On-farm practice the harvest after 150 days showed that the non-organic seeds produced more yellow grains (44.8%) than those of organic seeds (39.6%). A total grain per plant produced by the non-organic seeds was higher than those organic seeds, however, total percentage of the filled out organic seeds was higher (57.8%) than those non-organic seeds (40.1%). Organic seeds seem to be more dormant than those non-organic seeds after storage for 12 months. Grain weight of both non-organic and organic was 17-19 g per 1000 seeds. Germination of off-farm non-organic seeds was 98.0%, whereas those organic seeds were 95.0% at water content of 10.8% respectively. In view of seed physiology, organic rice quality better than those non- organic because they contain more filled out seeds, even though the organic rice harvesting time longer than those non-organic. Although off-farm study represented seed physiology of either organic or non-organic seeds, on-farm study needs to be further done on all aspects of seed physiology.

Abstract

Patchouli farmers are often faced with low quantity and quality of the extracted oil produced by the crop. These are primarily due to lack of understanding in the post harvest technology. Purpose of this study was to determine the rate of change in water content of patchouli for the period of drying process at different rate of air stream velocities and to determine the position of drying trays in dryer that provide the shortest period of bringing the plant material into 14% water content for given air stream velocities. Results indicated that the first and second lower trays (tray1 and tray 2) in the dryer provided the shortest period of drying the material at all air stream velocities. At 90 m min-1 velocity, both trays brought the material into 14 % water content at 21th interval of perception (126 h). Similarly, at 110 m min-1 and 125 m min-1 velocities, the same condition was found at 16th interval of perception (96 h) and 18th interval of perception (108 h), respectively.

Abstract

[GROWTH OF DRAGON FRUIT (Hylocereus constaricensis) STEM CUTTINGS AS AFFECTED BY CONCENTRATIONS AND DIPPING TIMES OF COCONUT WATER]. Dragon fruits (Hylocereus constaricensis) is commonly propagated vegetatively by using stem cutting. In this respect the use of natural plant growth regulator, such as coconut water, to promote the growth of the cuttings is very important. The objectives of this experiment were to evaluate water coconut concentration, dipping time of stem cutting in the coconut water, and the combination of both to promote the growth of dragon fruit cuttings. The experiment was arranged in Randomized Complete Block Design (2 factors, 5 replications). The first factor was the concentration of coconut water, consisting of 5 levels: 20, 40, 60, 80, and 100%. The second factor was dipping time of cutting in the coconut water, consisting of 4 levels: 2, 4, 6, and 8 minutes. The results showed that the increasing coconut water concentration had increased the shoot growth in a liner fashion. A similar trend was also observed for coconut water dipping time. The highest shoot growth was found on 60 % coconut water.

Abstract

[THE USE OF VERMICOMPOST FOR BIOMASS PRODUCTION OF LEGUME COVER CROP AND INOCULUM OF ARBUSCULAR MYCORRHIZAL FUNGUS]. Vermicompost is an organic fertilizer produced through the digestive system and microorganism inside the earthworm gut. Vermicompost is recognized to have positive effects on the plant growth and development of mycorrhizal symbiosis.The study was aimed to determine the optimum size (diameter and weight) of vermicompost for producing biomass of legume cover crop (LCC) and inoculum of arbuscular mycorrhiza fungus (AMF) of G. etunicatum. A glasshouse experiment was arranged in a randomized block design, involving different diameter size and weight of vermicompost as the treatments. Results showed that vermicompost is a potential substitute to inorganic fertilizer for production of LCC biomass and AMF inoculum.Vermicompost applied with  diameter < 250 µm weighing 150 – 172 mg produced  the highest  root dry weight of LCC, root colonization, and number of spores of G. etunicatum. A linear relation was found between root colonization and number of spores of G. etunicatum.

Abstract

Area under rubber tree stands has an economic potential for production of ginger if proper fertilizer application is implemented. Purpose of this study was to determine the effects of N and P fertilizers application on N uptake, N efficiency and yield of ginger grown under rubber tree stands. The experiment was laid in RCB design with a factorial arrangement of the treatments, consisted of four levels of N fertilizer (0, 3.375, 6.75, and 10.125 g plant-1) and three levels of P fertilizer (0, 9, and 18 g plant-1). There were three replications and 18 plant on each experimental unit. Results indicated that there were significant interaction effects between N and P fertilizers on N uptake and N efficiency. The expected maximum N efficiency of ginger plant was 14.01% as N fertilizer applied alone at 12.56 g plant-1. Similarly, the highest N uptake (1.170 g plant-1) was observed on N application at 13.755 g plant-1 without P. Weight of ginger rhizome was predicted to increase 0.2203 g plant-1 on 1 % increment of N uptake efficiency.

Abstract

Information on genetic variation, heritability, gene action and genetic advance were important in the development of soybean varieties adapted on Ultisol. The objective of this experiment was to estimate genetic variation, hertability, gene action and genetic advance from the populaton used in breeding program. Six genotypes, i.e Dempo, Cikuray, Davros, Orba, Sindoro and Wilis were intercrossed using diallel Griffings’ Method 2 Model 1 (1956). These six genotypes and 15 F1  hybrids were planted on Ultisol using randomized complete block design with three replications located in Medan Baru village, Bengkulu city in 1999. The results of this experiment revealed that all traits showed low to high genetic variation, high broadsense heritability, low to high narrowsense heritability and genetic advance. Date of flowering and root length were fully controlled by additive gene action, however harvest index was fully controlled by   negative dominant gene action and epistasis. Other traits were controlled by positive and negative partially dominant, and positive overdominant  genes.

Abstract

In response to the need of shade tolerant of soybean varieties for agroforestry, we conduct a research to find soybean variety which gave high response to AMF (arbuscular mycorrhizal fungus) and strain of rhizobia inoculation. Research was conducted in a greenhouse by three factor of randomized completely design and replicated three times using top soil of Ultisol from Bengkulu province. First factor was soybean varieties namely Wilis, Pangrango and Ceneng. Second factor was AMF inoculation with Acaulospora sp, Gigaspora margarita, Glomus etunicatum and Glomus manihotis. Third factor was rhizobia inoculation with TEKR 6.29 and KLKR 5.31 strains. Selected AMF and rhizobia isolates was obtained from previous research and taken from the rhizosphere of soybean plants grown on Ultisol of Bengkulu. All replications receive 1 ton ha-1 of farmyard manure and all biofertilizer replication receives 20 kg ha-1 Urea, 20 kg ha-1 SP36 and 60 kg ha-1 KCl. Chemical fertilizer application (80 kg ha-1 Urea, 80 kg ha-1 SP36 and 60 kg ha-1 KCl) used as control. Research result showed that there was a specific combination between soybean variety with AMF and strains of rhizobia. Wilis will gave highest response if paired with Acaulospora sp – TEKR 6.29, Gl. etunicatum – KLKR 5.31, Gl. manihotis- KLKR; Pangrango with Acaulospora sp – TEKR 6.29, Gl. manihotis – KLKR 5.31; and Ceneng with Gi. margarita –TEKR 6.29, Gl. etunicatum- KLKR 5.31, Gl. etunicatum – TEKR 6.29, Gl. manihotis – KLKR 5.31, and Gl. manihotis – TEKR 6.29. Research result also showed that Ceneng gave more consistently response than two other varieties and suitable with every AMF and rhizobia strains tested.
