Abstract

Deforestation speed was increasing fastly from 1,87 million ha/year on the 1985-1997 period to 2,6 million ha/year on 1998-2000 period This increase in speed cause many problems such as: a decrease in environment quality, the drastic decrease inforest timber production which affects timber supply,erc. There are many factors affecting a change in the forest coverage. At first, management of Forest Utilization Right (HPH) and the development of timber industry are perceived as the cause of the increase in deforestation speed. However, there are other argument that propose an increase in the number offarmers and nomad farmer in forest area as the cruse the change inforest coverage.The purpose of this study is to get a picture of the direct cause of the change in forest coverage . This study use panel data method for 19 provinces from I976 to 2000. The results show that there is a positive relationship between speed of deforesiation and forest coverage. Logging activity and forest conversion contribute to the change in forest coverage where forest conversion has bigger impact on the speed of deforestation. This analysis indicates that forest conversion is the major cause of deforestation in Indonesia. The conversion of forest into plantation is the major cause of deforestation in Indonesia. on the other hand, the number of small famers or people live inforest area has very little impact on deforestation.

Abstract

This research examines impacts of agricultural industry productivity improvement on sectoral and macro economic performance and household income. The CGE-AGRINDO model combined with CGE ORANI-F, INDOF, WAYANG, and ORANIGRD were used as a main tool of analysis. The data was computed using GEMPACK program. The study used data of I-O 2003. The are three simulations being examined, i.e. (1) improvement of agro industrial productivity, (2) simulation 1 plus improvement of agricultural productivity, and (3) simulation 2 plus improvement of financial institution. The policy simulations show that the impact of productivity improvement of agricultural industry tends to increase industry output and employment, but decrease the output price. The simulation also suggestt that productivity on agroindustry increases the macro economic performance and household income.

Abstract

The purpose of this research was to analyze fiscal and poverty performance, (1) to analyze fiscal policy impact on poverty performance, and (2) to determine strategic policy on poverty in North Sumatera Province. Model of fiscal policy in North Sumatera Province was built with the dynamic simultaneous equations system and used 2 SLS with SYSLIN and SIMNLIN procedures. In this study we alse used pooled data in 1990-2007 period. The results of this study were: (1) factors of fiscal performance in North SUmatera which were local tax and tax sharing were influenced by local GDP positively, on the other hand general allocation funds and local retribution were not influenced by local GDP, and (22) during fiscal policy, poverty performance decreased, which has interpreted with number of poor people in rural areas and number of poor in urban - poverty condition in urban area which was to decrease found and fluctuate, (3) in simulation section, decreased of illeteracy and health expenditure gave better impact on poverty and also increased local GDP in North Sumatera than other simulation. Finally, it was that Fsiscal policy, especially in health and education sector, will stimulate social life in the future

Abstract

UKM Mandiri Jaya dan UKM Sederhana merupakan usaha kelompok masyarakat yang belum produktif secara ekonomis, tetapi berhasrat kuat menjadi wirausahawan. Anggota UKM ini terdiri dari masyarakat ekonomi lemah. Mereka memiliki penghasilan yang sangat rendah. Kebutuhan hidup sehari-hari diperoleh melalui usaha pertanian dan peternakan ayam skala kecil. Usaha tersebut dilakukan pada lahan garapan. Sebagian dari hasil pertanian tersebut dijual ke pasar tradisional. Hal ini tentu tidak mampu memenuhi kebutuhan yang semakin meningkat pada era globalisasi saat ini. Kondisi ini diperburuk lagi bila saat musim hujan, lahan akan mengalami banjir sehingga tanaman tidak dapat dipanen untuk dikonsumsi dan dijual. Selama ini mereka juga sudah mencoba memelihara ikan untuk konsumsi keluarga namun usaha tersebut tidak dikelola secara profesional sehingga tidak mampu berkembang dan otomatis tidak dapat digunakan untuk menambah pendapatan keluarga. Dari kondisi demikian tercetuslah sebuah gagasan untuk membuat desain vertiminaponik. Vertiminaponik merupakan sistem budidaya yang memadukan antara budidaya ikan secara aquaponik dan budidaya tanaman menggunakan air atau yang biasa disebut hidroponik yang disusun secara vertikal. Pada sistem ini, dengan luasan lahan yang sama maka akan dapat dihasilkan dua komoditas sekaligus, yakni sayuran organik dan ikan. Kegiatan yang telah dilakukan memberi kontribusi positif yakni hasil panen sayuran hidrophonik dan panen ikan lele sudah dinikmati oleh mitra pengabdian. Pelatihan marketing online juga sudah diberikan pada mitra.
