Abstract

Nowadays, wood industry in Indonesia suffers from lack of wooden raw material because of the demand is greater than the supply. In order to solve this problem, we need to enhance the use of wood by optimalizing the use of wooden raw material wich has a great potensial, but not well used, for example hybride coconut wood. The purpose of this research were to determine physical, mechanical and chemical properties of hybride coconut wood and its vertically and horizontally variation in order to optimalize the use of hybride coconut wood. This research used three hybride coconut steems, the 6 cm disks were extracted from each stem at 1, 4, 7, and 10 m heights. The analyze of vascular bundle and parenchyma consisted of covered area per cm2 and their chemical composition. Hybride coconut wood had a low specific gravity because vascular bundle covered area was lower than parenchyma per cm2 and low wood substance portion. Low specific gravity caused low mechanical properties. Hight moisture content (specially fresh one) was cause by sugar and starch extractives which had high hygroscopic ability. These extractives content also caused it to be easily attacked by wood destroying factors. Parenchyma covered area per cm2 caused high sugar and starch content. Height and depth factors were visible influence at almost all basic properties of vascular bundle and parenchyma at different level.

Abstract

The Objectives of this study are: (1) to identify agricultural household characteristic in rural and urban areas, (2) to identify the factors that encouraging the process of labour transformation in rural and urban areas, and (3) to analyze the process of labour transformation impact to households income in rural and urban. The design of study is the case study in the district of Bogor. The sampling method use multistage sampling with data analyzing of: (1) descriptive analysis, (2) Binary choice model in logistic function, and (3) Income analysis. The results of study show that educational level of head of agricultural household in rural more than urban and conversely for income. The factors in wich influent the decision of head of household to transform in rural are age (X3) and income expectation from non-farm (5). In urban, the factors in which influent decision are self belonging of land (X1), the amount of working age of household family members (X2), the educational level of head of household (X4), and income expectation from non-farm (x5). Income level of houshold in rural and urban is not significant (Prob 0.2906). Mean while, the average of farm income in rural and urban is significant (Prob = 0.0028). The income of transformed farmer is more than pure farmer. The income level significant both rural (Prob = 0.0618) and urban (0.0110).

Abstract

Poverty still becomes main problem in this country. The categorization of the poor or not poor household based on the poverty line is difficult to be performed in practice. Therefore, it is needed to find other variables that could be used to characterize poor household. In addition, because the households that almost poor could become poor easily, it is also needed to analyze the probability of these household become poor household. This research use Susenas Data Kor 2003 from Badan Pusat Statistik for Jawa Barat province which includes explanatory variables: house physical condition, protein consumption, type of fuel/energy, ownership of asset, and also head of household characteristic. Result from logistic regression analysis shows some poor household characteristics: floor area per capita <= 8 m2, there's no closet, final place of feces exile is not tank, closet type is not goose neck, do not consume food with high protein, don't have motor vehicle or saving, electrics do not use gauge, head of household is a woman, amount of household members >= 5, head of household's age > 55 years. For the urban area, another characteristics are: don't have farmland, do not use gas, do not use electrics from PLN, using firewood, head of household's work status is erratic, head of household's education maximum is elementary school. For rural area, another characteristics are: house is not property of them selves; most of wall not made by cement; don't have precious goods, store, or productive asset; do not use kerosene. Ordinal logistic regression obtain model that explain relation between household status and its independent variables. However this model can not explain probability of almost poor household become poor household, because the household exactly have higher opportunity to be categorized as not poor. Probability of almost poor household categorized as poor household only 9.59% for urban area and 11.79% for rural area.

Abstract

The need of soybean in Indonesia grows from time to time. Now, Indonesia imports at about 1,1 milion ton/ha yearly. This condition indicates that the need of soybean in Indonesia can be a serious problem of agricultural sector in the future. Furthermore, the climate change issue as a result of human activity used a large amount of fosil fuel will derive a new problem for agricultural sector which requires a better strategy of anticipation. This point out the important of information in order to estimate the potential of soybean's yield in Indoensia in the future. In general, this research is designed to identify the evidence of climate change and to learn the impact of the climate change scenarios on the future of soybean's yield in Bandung district. For this purpose, literature study and analysis of global circulation model (data) data are applied for identifying the occurrence of climate change. Then, the impact analysis of these scenarios on soybean's yield is conducted by using climate and agricultural simulation model, which consist of statistic and mechanistic models. Analysis of the earth surface mean temperature shows the increasing of global air temperature has been started since 19's century with the occurence of increasing temperature from about -0.4 °C to about 0.1 °C in the year of 1940's. Then, the occurence of climate change in Indonesia can be identified using monthly rainfall data for a certain period. Previous study, which has been conducted by Kaimuddin (2000) shows the changing of rainfall pattern in Indonesia. Additionally, analysis on Global Circulation Model (GCM) data for various climate change scenarios reveal the evidence of rainfall and temperature changing variability in percentage for each model in year 2020, 2050 and 2080. The highest value of A2 scenario in come from NIESS, meanwhile for B2 scenario is GFDL. Then, the minimum value is mostly gained from ECHAM model. Moreover, the result of simulation using maximum and minimum value from those scenario for year 2020 decrease in almost of the whole area of Bandung.

Abstract

Study on the chemical compound of painted nettle (Coleus blumei Benth) leave extract and its anthelmintic activity against chicken tapeworm were conducted. Leave of painted nettle were collected and extracted with hexane, chloroform, ethanol and water. Phytochemical analysis was carried out to determine the chemical compound of secondary metabolites. Anthelmintic activity was evaluated with an assay using chicken tapeworm in a serial microplate dilution method by determination of efective concentration 50 (EC50) using probit analysis. The result of phytochemistry analysis showed that Coleus leaves consisted of flavonoid, steroid, tannin and saponin. Three of four extracts displayed strong anthelmintic activity with the higest activity belong to chloroform extract with EC50 5 mg/ml followed by n-hexane 9 mg/ml and metanol extract 10,2 mg/ml, while water extract has a weak anthelmintic activity with 106,2 mg/ml. In general, chloroform extract proved to be a more efficient extractant of biologically active compounds than either hexane, ethanol or water extract. The promising activity displayed by a number of extracts has led to further investigation of the active compound. Unfortunately, the result of invivo assay showed that the chloroform extract treatment with dose level 25 mg/kg BW could not to reduce the number of tapeworm in chicken. It is interesting for further investigate the differences of respon between in vitro and in vivo to determine involved factors.
