Attempt to increase yield of 4-6 month old exportable ginger was tested by ethepon applications. This experiment was carried out at IPB Experimental Station Tajur from November 1988 - May 1989, with rates of application of 0, 10000, 20000, 30000, and 40000 ppm by volume. Sprayed plots were combinations of rice husk mulching (0 dan 5 ton/ha) and N fertilizations of 0,200 and 400 kg N/ha. Except for tuber weight and total production, the growth parameters were not influenched by ethepon. The best application of 10000 ppm markedly increased the fresh tuber weight by 91,8% per hill or 81,3% of the total yield.

The brown planthopper (BPH) Nilparvata lugens Stal (Homoptera: Delphacidae) is one of the most important rice pest in Indonesia. Integrated pest management (IPM) is the only way of controlling the BPH. The use of resistant varieties is an important component of IPM. The development of BPH biotypes and agricultural practises cause the resistant varieties become susceptible in only 4-6 growing seasons. Understanding BPH - rice plant interactions are necesary. This greenhouse and laboratory studies were to unravel the mechanism and plant chemicals that might play a role in rice plant resistance of selected rice varieties: Cisadane, IR36, IR48, IR64, IR56, Kelara, and Bahbutong. Pelita I-I was used as susceptible check. The BPH colony originating from catches in 1986 in Yogyakarta was used in this study. Various experiments were carried out: evaluation of plant damage, the preference of BPH for feeding and ovaiposition, and population development study. The plants contens of protein, amino acids, water, potassium, calcium, and silica were measured. The mechanism of plant resistance to BPH on IR36, IR48, IR56, IR64, Kelara, and Bahbutong were identified as non-preference and antibiosis. The antibiosis mechanism was more prominent in IR48 and Bahbutong. The plant content of protein, potassium, calcium, and silica may take part in the basis of resistance mechanism. Further studies will be carried out.

Ruteng mountains are inhabited by the tribe Manggarai. Local community in the mountains of Ruteng have ethnobotany knowledge in utilization forest plant to meet their needs. Loss of traditional knowledge would have negative impacts on forest resources, because the indigenous people would have less knowledge on sustainable ways to manage the existing forest resources so that a research is required to identify the status of traditional knowledge. This study aims to analyze the level of knowledge of ethnobotany, retention rate, and the rate of change of the annual retention on the indigenous people in the Ruteng mountains. The research was conducted in the Kampung Mano, Lerang, and Wae Rebo, Manggarai District within the Province of Nusa Tenggara Timur in the period of July-December 2014. Data was obtained through Focus Group Discussion (FGD), semi-structured interviews with 90 respondent, and in-depth interviews. Data obtained were analyzed for the level of ethnobotany knowledge, ethnobotany retention index, and testing the significance of the factors that affect the level of knowledge with Kruskal Wallis test and Man Whitney. The results of the study shows that the Manggarai communities in the Mountains of Ruteng have local knowledge to meet daily needs, especially food, and medicine through the utilization of forest plant. The level of ethnobotany knowledge is high because they use forest plants, practice traditional rituals, and inheritance knowledge. The ethnobotany knowledge of young generation decreased which can give negatif impact to forest conservation.

The Objective of research to acknowledge the hypothesis: outreach islamic microfinance for the poor household of agricultural sector at rural Bogor West Java. The majority of the poor community in Indonesia stay at rural areas. Lack of access credit/financing generally seen as one of the main reasons why many people remain poor. Credit/financing as a powerful instrument to help poor people break out of the vicious cycle because it has the potential to improve income and savings, consequently, enhance capital accumulation, and reinforce high incomes, but providing credit to the poor of agricultural sector in many cases is a very costly activity. Bank isn’t interest to serve it. Hopefully, islamic microfinance institutions reaches to more the poor of agricultural sector. The average loan is the most commonly used to measure the degree of microfinance institutions (MFIs) outreach to poor customer segments, but it is very simple. Using the CGAP (Consultative Group to assist the poorest) method, the poverty multidimension of islamic microfinance outreach was measured. The result of study showed that islamic MFIs didn’t reach the poor household of agricultural sector at rural Bogor West Java.

Prebiotics are food ingredients that selectively stimulate the growth of probiotic bacteria in the colon. Resistant starch (RS) is the starch that can not be digested by digestive enzymes and resistant to gastric acid so it can reach the colon to be fermented by probiotic bacteria. There are treatments to increase the content of RS such as: autoclaving-cooling cycling, combination of lintnerized with autoclaving-cooling, and combination of debranching pullulanase with autoclaving-cooling. The results of techno-economical study showed that the combination of fermentation followed by autoclaving-cooling can be used as an alternative technique to increase the content of resistant starch in food more effectively and efficiently.

Lowland is the fragile land which is sensitive toward modification. The accurate and integrated management is substantially needed to utilize the lowland. This study analyzed the integrated lowland management in Mulia Sari Village, Tanjung Lago Subdistrict, Banyuasin Regency, South Sumatera Province. Sampling was chosen randomly consisted 21 respondens. Primary data: the farmers typical and farming system, were collected by using questionnaire while doing observation and purposive interviewing method. Qualitative approach was used to analyze the data. The result represented that the farmers typical substially determine the integrated lowland management. 80% people in Mulia Sari Village are farmers. Average farmers are between 25-65 years old. 75% farmers are male which is higher than female farmers that is 4.7%. More or less 50% farmers do not comply nine years learning programme. 33% of farmer’s educational level was only elementry school. Approximately, 47.61% graduated junior high school. They got land between 0.5-4 acre and more than 30% rented. The farming system of lowland need to consider water and land management. Both water and land management are the primary requirement in the integrated lowland management. The integrated lowland management in Mulia Sari Village is hardly to apply. It still needs strategic policy and elucidation which are compatible with the farmer’s typical and the lowland ecosystem.

The native fishermen are distributed in Manokwari coastal and have currently limited access to fisheries resource. This condition give vulnerable risk to potential utilization of fisheries resources to face vulnerable risk of local fishermen base on ecologycal aspect to take a wisely step to the problem. This research was conducted in April-September in 8 coastal district in Manokwari Regency. The result showed that native fishermen is medium vulnerable with value 0.57 to the number of catches, the composition of the fish and the fishing ground distance area. If this condition continues it will affect the existence of the status of local fishermen wich needs a partisanship in favor of the independence of local fishermen.

The use of mersawa wood and particleboard as a materials has been increasing for building constructions and decorative purpose. In previous study reported that, these materials provide a high rate of wear caused by abrasion (high silica) and resin content. This article presents the characteristics of wear on the clearance face of newly multilayer-coated K10 cutting tools when milling mersawa wood and particleboard. The K10 cutting tools were coated with monolayer titanium aluminum nitride (TiAlN), multilayer TiAlN/titanium silicon nitride (TiSiN), and TiAlN/titanium boron nitride (TiBN). Mersawa wood with density of 0.80 g/cm3 and particleboard with a density of 0.61 g/cm3 were cut using the coated tools and uncoated K10. Cutting tests were performed on computer numeric control router at a high cutting speed of 17 m/s and a feed rate of 0.1 mm/rev to investigate the wear characteristics on the clearance face of these coated tools. Result of research shown that the coated tools experienced a smaller amount of wear than the uncoated tool when cutting the mersawa and particleboard. The best coating among other coated in this study was multilayer TiAlN/TiBN. The high hardness, low coefficient of friction, high resistance to oxidation, and high resistance to delamination wear of the multilayer-coated TiAlN/TiBN tool indicate a very promising applicability of this coating for high-speed cutting of abrasive woods and wood based materials.

Biofertilizer is a substance which contains microorganism and promotes plant growth by increasing the soil nutrient availability. The aim of this study was to analyze the growth and production of lowland and upland rice by using the biofertilizer in acid soils. Seven isolates of bacteria were used as biofertilizer, i.e. Bacillus sp., two strains of Pseudomonas sp., two strains of Azospirillum sp., and two strains of Azotobacter sp.. The treatments of this study were without fertilization, compost, 100% NPK, compost enriched with 7 isolates, compost enriched with 7 isolates + 50% NPK, compost enriched with 4 isolates, and compost enriched with 4 isolates + 50% NPK. The results showed that biofertilizer in compost improved nutrient content in acid soil, and increased rice growth and production as well. Compost enriched with 7 isolates 50% NPK showed the highest rice yield production both in the lowland and upland rice. The biofertilizer could reduced 50% utilization NPK fertilizer dosage in the first growing season.
