Abstract

This research was conducted because the uncertainty in the tax amnesty policy. The purpose of this research is to analyze the effect of taxpayer’s expectation of future tax amnesty, tariff period system, tax penalty and audit towards tax compliance in tax amnesty policy, using experimental economics. The result shows that, a tax amnesty followed by strict audit and tax penalties will rise tax compliance. Tax amnesty policy is best applied once in a lifetime, because the expectation of the taxpayers towards future tax amnesty will result in lowering the compliance. Taxpayers prefer the lowest rate on tariff period. ======================== Penelitian ini dilakukan karena ketidakpastian keberhasilan dari kebijakan pengampunan pajak. Tujuan penelitian ini adalah untuk menganalisis pengaruh dari faktor ekspektasi masyarakat akan adanya pengampunan pajak di kemudian hari, sistem tarif pengampunan, denda, dan pemeriksaan pajak terhadap kepatuhan pada kebijakan pengampunan pajak dengan menggunakan metode ekonomi ekperimental. Hasil penelitian menunjukkan bahwa pengampunan pajak diikuti dengan penerapan denda dan pemeriksaan yang ketat akan meningkatkan kepatuhan pajak. Kebijakan pengampunan pajak sebaiknya diterapkan satu kali saja karena jika masyarakat berekspektasi akan adanya kebijakan serupa di kemudian hari, wajib pajak akan menunggu kebijakan tersebut dan tetap tidak patuh. Wajib pajak umumnya menyukai tarif pengampunan terendah.

Abstract

Land use changes in upstream cause flooding in the middle and downstreams so that appropriate spatial planning is required. The study aims to (1) analyze the forest management in ecologycal region percpective community, unilateral and bilateral on the boundary areas of Indonesia and Timor Leste, (2) analyze dependence of spatial-ecology with income farmers, and (3) analyze descriptively the spatial planning of border regions. The data used were secondary and primary data which were obtained from Indonesia and Timor Leste. Primary data sampling technique using multistage sampling, namely cluster sampling for the sample village representing the upstream, middle, and downstream of the watershed; while the sample of farmers using purposive sampling. The analysis used was descriptive analyisis which was used to analyze management of forest in ecologycal region on boundary area. Then, the spatial durbin model was used to analyze the dependence effect of spatial-ecology on farmer income in transboundary watershed. The spatial durbin model showed that farmers? income in the downstream of transboundary watershed will be reduced because patterns of farming on upperstream transboundary watershed tends to be exploitative. This implication required administrative and spatial ecology perspective in boundary spatial planning.??

Abstract

menentukan sebaran dari nilai-nilai atau kejadian-kejadian ekstrim. Metode EVT terdiri atas dua metode yangmenggunakan sebaran yang berbeda, yaitu metode Generalized Extreme Value Theory (GEVD) dan Generalized ParetoDistribution (GPD). Nilai VAR sendiri adalah nilai harapan rugi maksimum (maximum expected loss) dari nilai aset atausaham pada suatu periode tertentu dan pada tingkat kepercayaan tertentu. Hasil penelitian dengan menggunakan dataperdagangan saham pada Bursa Efek Jakarta (BEJ) menunjukkan bahwa metode GEVD dapat menduga nilai VAR denganlebih baik dibanding metode GPD.

Abstract

Selama tiga tahun terakhir, untuk dua semester pertama, selalu terdapat mahasiswa Program Studi Statistika  Sekolah Pascasarjana IPB yang tidak sanggup memenuhi persyaratan yang telah ditetapkan.  Karena itu menjadi penting untuk mengetahui faktor-faktor yang mempengaruhi keberhasilan mahasiswa dengan menelusuri latar belakang pendidikan S1 dan prestasi akademik mahasiswa selama S1.  Penelitian ini dilakukan pada mahasiswa S2 Program Studi Statistika angkatan 1991 - 2002.  Pendekatan analisis yang digunakan adalah Metode Pohon Regresi (Regression Tree). Faktor-faktor yang diduga mempengaruhi keberhasilan mahasiswa adalah jenis kelamin, status perkawinan, usia, pekerjaan, asal  perguruan tinggi S1, program studi S1, nilai mutu rata-rata (NMR) yang dicapai untuk semua mata kuliah selama S1, nilai mutu rata-rata (NMR) untuk semua mata kuliah statistika selama S1, dan nilai mutu rata-rata (NMR) untuk semua mata kuliah matematika selama S1.  Hasil analisis dari ke tiga pohon regresi menunjukkan bahwa jenis pekerjaan, asal perguruan tinggi dan NMR STK S1 adalah peubah yang sangat berpengaruh terhadap keberhasilan mahasiswa S2 Statistika.  Mahasiswa  yang berasal dari perguruan tinggi BHMN lebih unggul dibandingkan mahasiswa yang berasal dari perguruan tinggi Jawa non BHMN dan Luar Jawa.   Kata kunci : NMR, statistika deskriptif, pohon klasifikasi, pohon regresi

Abstract

Pengkajian masalah voting langsung di dunia yang sesungguhnya seperti di MPR/DPR tidak memungkinkan untuk dilakukan. Dengan penelitian laboratorium yang memanfaatkan Teori Induced-value, dapat dikaji faktor-faktor yang mempengaruhi hasil voting sesuai dengan tujuan penelitian ini.Penelitian ini berkesimpulan bahwa dengan voting tertutup jumlah peserta voting yang memilih diluar koalisi lebih besar daripada dengan voting terbuka. Demikian pula dengan imbalan tambahan (polotik uang), semakin besar nilainya semakin besar pula peserta voting memilih diluar koalisi. Tahapan voting dapat juga menghambat jumlah peserta voting memilih diluar koalisi.Kata kunci : penelitian laboratorium, teori induced value

Abstract

This paper studies the effect of domestic and foreign macroeconomy performances on the foreign direct investment (PMA) in Indonesia, employing descriptive and inferencial (econometric model) analyses. The national economic growth and national interest rate affect significantly PMA in Indonesia. While the national inflation rate positively -effected on PMA, but results show that hyperinflation contributes to decreasing PMA. The macroeconomic improvement in some _competitor countries, especially Chinese and Thailand tends to decrease PMA in Indonesia. However, the improvement of macroeconomies in Singapore and Malaysia can increase PMA in Indonesia. Therefore, bilateral relationship with these countries must be intensified. In addition, although the economic growth of some More Developed Countries (MDCs) has positive relationship with PMA in Indonesia, but their effect were not significant statistically, except Canada. This implies that global finance crisis, especially in USA and european countries would not largely effect on PMA in Indonesia.

Abstract

Increasing productivity of rice generally depends on a variety of additional inputs. Various systems are designed for farmers to increase incomes and improve land productivity. SRI method is a potential technology to increase rice production management based on the cultivation of land, plants and water through the empowerment of groups and local knowledge-based eco-friendly activities. The application of SRI method requires a study of innovation adoption and optimal strategies for farmers. This study uses institutional descriptive analysis; LFA (Logical Framework Analysis) and experimental economics. The results showed that (1) The role and focus of government institutions is an increase in production through the application of various technologies. Performance of local institutions have an important a role of cultivation introduction and depends on the active community leader or head of the farmer or P3A Mitra Cai; (2) Incentives system for farmers in the application SRI paddy method is marketing insurance with favorable price, (3) the application of SRI paddy cultivation requires strengthening group farmer and P3A Mitra Cai in regulating water, organic agricultural input and marketing of products through the application of water fee rates (ipair) based on fair remuneration system; and (4) the incentives for farmers to encourage the application of SRI paddy cultivation is the provision compensation if there is a decrease in production. The existence of information on SRI Method have real impact. Keywords: food security, SRI (System of Rice Intensification), water efficiency
