A research of induced polarization and very low frequency method was carried out at Sangon Village, Kulonprogo to identify mineralization zone. The result of these methods were able to be used to ...support each other. Mineralization zone is shown by high resistivity and high hargeability area of induced polarization method, and is also shown by high electric current density area of very low frequency method. Interpretation of resistivity and chargeability model shows that mineralization zone is mostly located at the depth below 10 m from surface. On the other hand, interpretation of electric current density models at depth 10 m and 20 m show that mineralization zone is not well distributed respect to alteration zone, which is the character of low sulfidation epithermal type, mostly at north-south direction.
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.
The purpose of the present study was twofold. First, the study aimed to validate the refined Bahasa Indonesian (BI) version of the Social Axioms Survey (BI-SAS). Confirmatory factor analysis showed ...that four out of the five dimensions of social axioms identified in the pancultural analysis, namely social cynicism, reward for application, religiosity, and fate control, were empirically robust as indicated by the dimensions' acceptable internal consistency (Cronbach alphas ≥.60) and sig nificant factor loadings of their a priori items. Second, underpinned by theory of planned behavior (TPB), the study examined the role of social axioms as predictors of behavioral intentions in studying, donating, and praying, and of three proximal antecedents of such behavioral intentions (viz. the attitudes toward behavior, subjective norms, and perceived behavioral controls or PBCs). Multiple regression analyses demonstrated that social axiom dimensions had differential relationships with the attitudes, subjective norms, and PBCs of the three behavioral domains. For all behavioral domains, social axioms accounted for a significant amount of the variances in the attitude, subjective norm, PBC, and behavioral inten tion. Social axioms also explained a significant amount of the variance in the intention to study over and above the proximal antecedents of behavioral intention.
An assessment on fertilizer recommendation had been executed in Rainy Season 1997/1998 in eight villages of Central and East Lombok District, Province of West Nusa Tenggara. The assessment was ...carried out on farmer's land (natural field) and managed by the farmers themselves but supervised by field agricultural extensionists (PPL). Tested treatments were (1) local recommended fertilizing dose, (2) fertilizing dose the same as the recommendation with P source of DAP as control 1 and (3) fertilizing dose the same as the recommendation without KCl fertilizer. The objective of the assessment was to validate existing fertilizing recommendation (issued by Provincial SPH Bimas, Province of West Nusa Tenggara) and to include composite-fertilizer DAP as an alternative of P fertilizer at a time. The results of the assessment showed that SP-36 fertilizer was as effective as DAP fertilizer for P source to rice growth and production. KCl fertilizer utilization did not positively response on IR-64 rice variety in all assessment sites except in Village Bilebante. The Provincial SPH Bimas of West Nusa Tenggara Province's fertilizing recommendation was still appropriate to be applied except for Sub-districts Selong and Pringgabaya which were recommended to apply KCl fertilizer. It is still to be furtherly investigated
Pengujian rekomendasi pemupukan telah dilaksanakan pada MH 1997/98 di delapan desa di Kabupaten Lombok Tengah dan Lombok Timur, Nusa Tenggara Barat. Pengujian menggunakan sawah petani (petak alami) dan dikelola oleh petani dengan pengawasan oleh Ppl. Perlakuan yang diuji adalah: (1) Takaran pupuk sesuai dengan rekomendasi setempat, (2) Takaran sama dengan rekomendasi dengan sumber P dari pupuk majemuk DAP sebagai pembanding-1 dan (3) Sama dengan rekomendasi, tanpa diberi pupuk KCl, bagi yang direkomendasikan KCl atau diberi KCl bagi yang direkomendasikan tanpa KCl. Pengujian bertujuan untuk menentukan validasi rekomendasi pemupukan yang telah ada (dikeluarkan oleh SPH Bimas Tingkat I NTB), Sekaligus memasukkan pupuk majemuk DAP sebagai alternatif pupuk P. Hasil pengujian menunjukkan bahwa pupuk SP-36 dan DAP sama efektifnya sebagai sumber P terhadap pertumbuhan dan produksi padi. Penggunaan pupuk KCl tidak memberikan respon yang positif terhadap produksi padi IR-64 di lokasi pengujian kecuali di Desa Bilebante. Rekomendasi pemupukan oleh SPH Bimas Tingkat I NTB masih sesuai diterapkan/dianjurkan kecuali untuk lokasi Kecamatan Selong dan Pringgabaya yang direkomendasikan menggunakan pupuk KCl, perlu dikaji lebih lanjut
