Abstract

Global warming which leads to climate change has potential affect to Indonesia agriculture activities and production. Analyzing rainfall pattern and distribution is important to investigate the impact of global climate change to local climate. This study using rainfall data from 1976-2010 from both lowland and upland area of Lampung Province. The results show that rainfall tends to decrease since the 1990s which related to the years with El Nino event. Monsoonal pattern- having rain and dry season- still excist in Lampung; however, since most rain fell below the average, it could not meet crops water need. Farmers conclude that dry seasons were longer and seasonal pattern has been changed. Global climate change might affect Lampung rainfall distribution through changes on sea surface temperature which could intensify the El Nino effect. Therefore, watching the El Nino phenomena and how global warming affects it, is important in predicting local climate especially the rainfall distribution in order to prevent significant loss in agriculture productivities.

Abstract

The objectives of this research were 1) to determine soil moisture regime based on rainfall and temperature data; 2) to make a correction of the first objective based on soil moisture surplus and deficit calulation; 3) to study the pattern of soil moisture regime distribution in the research area. The field sampling tehniques applied in this research was stratified proposed sampling. Landform unit was applied as strata. Soil depth and texture were considered during field soil sampling within the landform unit. Rainfall and air temperature data were analyzed using Newball Simulation Model (NSM) to determine a tentative soil moisture regime. The tentative soil moisture regime was corrected using calculation soil moisture regime of soil moisture surplus and deficit. The soil moisture surplus and deficit was calculated based on soil depth, soil texture, rainfall, and temperature data. The result of this research were 1) soil moisture regime estimated using NSM ranged from ustic to udic; 2) soil moisture regime corrected using surplus and/ or defiit alulation of soil moisture ranged from xeric to udic; 3) the pattern of soil moisture regime distribution in the reaserch area was not only controlled by the pattern of rainfall – air temperature distribution but it was also controlled by the pattern of soil – landform distribution. Under the some amount of annual rainfall, shallow and coarse texture soils have drier soil moisture regime than deep and fine texture soils.

Abstract

Nowadays, the comprehensive and integrated rural development concept has been considered as the right approach in order to combat the root of rural poverty. By its main concern on area planning, i. e. the availability of planning apparatus at local (regional) level, comprehensive local (rural) resource analysis, and multi-disciplinary approach, it is expected that the weakneses of centralized planning which, among others, concentrates on economic growth can be reduced or even eliminated. This paper tries to explain the place of social service planning in the rural development concept above. The approach used is by discussing the place of service planning in the national development policies; collective decision making system, especially related to planning procedure and process; and social service problems in rural areas.

Abstract

This research was caried out in Plumbon district of Mojolaban and it was intended to find out demographyc characteristic and migrant social economy, way of mobility process, factor, and reason which affect mobility and social economy effect of mobility action to the migrant family. The applied method to research was surveying and the area of the research was selected purposively, respondent in the surveying amount to 60 which was collected at random out of 320 population. The research outcome shows that mobility agent include in the group of potential age i.e domination of age 22 – 44 groun amount 63,33 percent. Thier education are relatively low i.e amount to 83.33 percent graduated from grammer school and lower. Or if it is more detailed there are 43.33 percent that did not go to school and did not pass grammer school. The work of respondent are 65 percent as workers of factory and construction. Average income per mount of migrant is relatively low i.e Rp 121.417 – only 30 perecent of then do the side job. The reason is that they have no more time as their working hours is long i.e 48 working hours per week, beside a larger part of them have not special skill. Before mobility action their work in farming, it mean that there  happened the mobility of working. Decision to realize the mobility emerged from respondents them selves and the main information workes of destination area is an informal one. The effecct of go back and forth mobility to the migrant family is their income improvement, if it is compared to their income before mobility, it includes the problem of providing food, clothing, and education.
