Abstract

Selo, a small agricultural-based village in Boyolali, Central-Java, Indonesia has initiated small-scale rural biogas adoption as it presumably reduces the consumption of LPG, firewood, chemical fertilizer and (women’s) overall workload, which especially suitable due to the relatively high use of cattle in that area As environmental problems such as global warming from fossil fuel consumption and land degradation from deforestation and overuse of chemical fertilizers, and socio-economic problems as gender empowerment and self-sufficiency are becoming more pressing, it is useful to analyse the benefits of biogas as an alternative renewable energy technology (RET) provision in rural areas. This paper aims to assess the benefits of rural biogas adoption from an economic perspective, through calculating the direct and indirect benefits obtained from biogas adoption in Selo. For this, a field survey was carried out in Selo to ask questions to biogas users (N=21) and non-users (N=5) on their energy and fertilizer consumption, as well as emissions reductions resulting from biogas adoption. Based on the analysis, oon average, a household with biogas saves 490 kWh month–1, 20,000 IDR month–1,185 kg CO2e month–1.Chemical fertilizer consumption remains remarkably high, which may due to a lack of awareness on the potential of digester slurry by the farmers, for indeed, reduction of chemical fertilizer use would help address some environmental problems. Biogas quality of one household has also been determined by comparing its heating value to that of methane; the methane percentage (MP) was approximately 31%. The quality is considerably lower than expected from the literature (i.e. around 60%), which may be due to the farmers neither mixing nor supplying water to the dung. Trainings providing methods for improving digester overall effectiveness to particularly the women-folk may enhance digester management and thus biogas production, as they form the main primary operatives. Despite the room for improvement, the existing results clearly show that biogas adoption significantly reduces greenhouse gas (GHG) emissions, household energy costs, workload, improves environmental conditions and generates income through carbon credit exchange. Therefore, under the notions of sustainable development, environmental preservation and self-sufficiency, policy makers and NGOs should expedite their support in biogas development, e.g. by providing subsidies and awareness raising.

Abstract

Early geographyc information systems facused on processing attribute data and geographic analysis, and had only rudimentary graphic and mapping capabilities. Phenomenal increase in computer processor speed and power in 1970s and 1980s had a major influence on GIS development. By the late 1980s, the technologies of the three main types of geo-based system had merge to various degrees. Most systems today offer powerfull capabilities for graphic production, processing of attributes, and analysis

Abstract

Settlement is the most important area in the activity of disaster mitigation. The Biggest detriment caused by disaster is generally placed at the settlement or residential area. Thereby, the identification of the settlement characteristics is required to be able to recognize the disaster risk. This research aim to identify the characteristics of the rural settlement on the coastal area in the District of Kulonprogo. This area is chosen based on the consideration of coastal morphological characters. This area have slopeslightly coastal zone which face to Indonesian Ocean. In this situation, hence in the event of tidal wave, there will be wide spread overflowing run up water. Two approaches is used in this research, they are; (1) Morphological Approach, and (2) Behaviour Approach. Both of the approaches is conducted with comparative perspective. The existance of the settlement which have been filtered through settlement and coastal tipology are compared. The data are collected and analyzed through: (1) Mapping and GIS tools; (2) survey method; (3) Indepth interview; and (4) statistical analysis. Thirty household are selected proportionally to setlement unit as a respondent in indepth interview. In order to analyze the data, descriptive analysis (frequency tables) and crossed tables are used. This research indicate that rural settlements on the coastal area in the District of Kulonprogo are spatialy distributed as a ribbon pattern. This pattern are coincident with the shape of the coast and the linearity of the road as well. Most of the buildings are in good condition, and they characterized by moderate housing density. In the term of coastal morphology, the research area is dominated by sandy coast with slopeslightly relief. Generally, the socio economic condition of the peoples living there are low to medium economic level, low education, and rarely medium income. Related to tidal flood vulnerability, this research area is the second level (moderate) hazardeous zone.

Abstract

This study aimed: (a) to determine the general water balance at the Upstream and Midstream of Bengawan Solo Watershed by using Thornthwaite-Mather model, and (b) to determine the fulfillment of domestic water demand in the Upstream and Midstream of Bengawan Solo Watershed. Prevailing climate change has affected the condition of water source in Upstream and Midstream of Bengawan Solo Watershed. One of the impacts was extreme fluctuation of meteorological water availability that might cause flood and drought. Survey was selected as the research method while descriptive quantitative method was used for data analysis. The findings indicated the difference between precipitation and corrected evapotranspiration (P-EP) at the Upstream and Midstream of Bengawan Solo Watershed was between (-11.19 mm) to (78.56 mm). The highest value was obtained by Bambang Sub-watershed and the lowest was Wiroko Temon Sub-watershed. Positive value indicated the water surplus while negative value indicated water deficit. Domestic water demand for local communities was in the range of 50,782,500 liters to 131,690,700 liters, and the level of water availability varied, namely fulfilled and unfulfilled.

Abstract

Sea surface temperature plays an important role in air-sea interactions. This research was conducted to understand seasonal and interannual variations of sea surface temperature in the Indonesian waters. The data used in this research was daily sea surface temperature in 1986 to 2015 which was obtained from the Physical Oceanography Distributed Active Archive Center - National Aeronautics and Space Administration. Method used in this study was the anomaly analysis. The result showed that the seasonal and interannual variations of sea surface temperature in the Indonesian waters varied. Seasonal variations of SST in the Makasar Strait, Sulawesi Sea, and Halmahera Sea were low. High seasonal variations of sea surface temperature occurred in the southern waters of Java, Timor Sea, Arafura Sea, and Banda Sea, which were allegedly due to the upwelling process. In addition, interannual variation of sea surface temperature in the Indonesian waters fluctuated. From 1986 to 2000, it showed a negative anomaly dominant. Meanwhile, from 2001 to 2015, it showed a positive anomaly dominant. The effect of Indian Ocean Dipole on the fluctuation of sea surface temperature in the Indonesian waters was stronger than ENSO. Within the last 30 years, the sea surface temperature in the Indonesian water indicated a rising trend. The highest sea surface temperature rise occurred in the Halmahera Sea that reached 0.66 OC/30 years and the lowest was in the Timor Sea of 0.36 OC/30 years.

Abstract

This study is carried out in Nusukan, Banjarsari, Surakarta. The problems that are related to economic crisis in Indonesia are the supply of contraception, the weakening of people purchasing power so they influence the realization of family planning program. The goals of the study are: to know the supply of contraception for poor household, to study the influence of the effect of economic crisis for the participant of family planning, to study the change of birth control and its effective strategy and to know the quality of family planning service. The data are collected using observation, and questionnaire. The study takes the area in which it has more productive couple, the percentage of poor families and the prosperous families I that belong to productive couple whose age 20 to 49 years old, at least they have two children, and participant of family planning or ever followed it. The result of the study shows that 82% respondents can get contraception easily before and at economic crisis. It is one of the important factors, for which the participant of family planning is still high. Although the economic crisis influences the price of contraception and family Income, it does not affect the participant of family planning. 87% respondents participate actively the family planning. This shows that the people have realized the importance of family planning program. There is an impact of economic crisis for the change of the ways of birth control. 38% respondents have changed over their strategy from modern to traditional contraception and the contrary, and from modern contraception to the other one. Some of them are abstention. The level of the people adaptation is high enough. They use various ways to prevent of being pregnant. 92% respondents do not want to be pregnant. If it happens an unwanted pregnancy, 15% of the respondents will abort their pregnancy. This is the challenge for the officers and the government to supply safe and accurate contraception and to give clear explanation about the effect of abortion from healthy and religious aspect. The service of family planning by the government and private institution is good enough (81%). Respondents can get contraception (especially tablet) easily; cheap and free of charge, but the other ones such as spiral is more difficult because it is more expensive and limited.

Abstract

Leather industry in Magetan covers two forms; they are tanning and leathercraft. During 1960 and 1970, the leather industry decreased in its production, but in 1990 Magetan becomes the center of leather industry. Its development appeals to be studied closely. The goals of this study are to know the relation between tanning and leathercraft, the connection between these industries and other economic ativities, and their connection with production factor. This study uses survey methhod. The respondents are taken proportionally from both of those leather industries. The data is obtained inetrviewing the respondents with questionnaire that related to the input and out put of the industry. The result of this study shows that there is no relationship between the kind of industries (small and household industry) and its capital, especially in its raw material (44,44%). The relationship between tanning and leathercraft is low, because it is only 24,2% input of leathercraft which taken from output of tanning. The region relationship for tanning is larger, because the products that are sold to other regions are 97,22% for tanning and 68,29% for leathercraft. Its relationship to other sectors especially for labour supply is 56,48% from farming and trade sectors in marketing.

Abstract

This article is about development a regression equation to determine the perception of thermal comfort for pedestrians in the humid tropical climate. Methods used was field studies and questionnaires to 60 samples as respondents in Manado. Each of the respondents was asked to act as pedestrian but walked on a treadmill for 2 minutes 5 five times. They regrouped into two parts, one who walked under open-sky and another group was under the shade of trees. Measurements of climate variables include air temperature, air humidity, radiation temperature, land surface temperature and solar radiation. Measurements to the respondents were their height, weight and skin temperature. By using statistical approach it is obtained a regression equation "Y=- 6.1369 + 0.479 Adu + 0.1143 Ta + 0.0376 Trm + 0.2541 RH + 1.6793 clo". The equation was then validated by comparison with other equations of non-tropical humid climate case. It is found that the empirical regression equations of outdoor thermal comfort developed by means of field studies in a certain climatic conditions could not be applied for a wide range of climate.
