ANALISIS SPASIAL SEBARAN LAHAN KRITIS DI KPHP UNIT XII BATANGHARI PROVINSI JAMBI

Critical land occured as a result of land cover changes from vegetated into non vegetated land or the composition of the vegetation has changed. This study aimed to analyze the distribution of land critical at KPHP Unit XII Batanghari. Critical land analysis was based on the Perdirjen PDASHL Number P.3/PDASHL/SET/KUM.1/7/2018. Land is classified into 5 levels of criticality, namely: non-critical, critical potential, somewhat critical, critical and very critical. The parameters used in determining the level of criticality of the land are: land cover, erosion-prone class, slope class and the presence of land inside or outside the forest function. Spatial analysis used by Geographic Information System (GIS) and remote sensing technology. GIS is able to analyze and represent geographic phenomenon. Landsat 8 imagery was analyzed to obtain land cover clasification. The results of the analysis showed that critical land level of KPHP Unit XI Batanghari consisted of 3,609 ha (4.45%) that classified as very critical and 3,599 ha (4,43%) as critical land. Then, land with a somewhat critical level had the largest area, namely 26,024 ha or 32.07% of the total area of KPHP Unit XII Batanghari. The landcover was the main parameter to determine the level of criticality of the land. The openland cover type had the maximum score 60

Constructing the Index of Indonesian Monthly Private Consumption Expenditure

Private consumption expenditure (PCE) contributes a major share in Indonesian GDP and its growth has been dominating the economic growth. PCE is also linked directly to the welfare of Indonesian people making it even more relevant for its close monitoring. However, despite the high volatility of macroeconomic conditions due to both global and domestic disturbances, indicators that measure PCE in frequency higher than quarterly is not yet existent in Indonesia. This paper is the first attempt to construct a monthly index of private consumption expenditure for Indonesia. Using a methodology based on the experience of other countries and constrained with data availability, we devise the index based on four statistically relevant variables: value added tax revenue, excise tax revenue, electricity consumption, and fuel consumption. Using the weights estimated based on the principal component analysis we found that our monthly PCE index fits well and correlate highly with the quarterly private consumption expenditure from the national accounts data. We hope that our initial attempt to construct the monthly PCE index will encourage others to devise even better measure of monthly consumption indicators.Private consumption expenditure, Macroeconomic Policies, Indonesia
