Abstrak: Crude Palm Oil (CPO) is a vegetable oil derived from palm oil . Indonesian palm oil production are not accompanied by high domestic processing but many serve as export commodities. However, based on data from the Ministry of Industry in 2009 to 2011 the number of Indonesian exports gradually decreased. The decline in Indonesia palm oil exports in the period 2009-2011 due to external and internal factors. External factors due to the global economic crisis, and the saturation of the production of palm oil in the world market. Internal factors due to domestic palm oil downstream industry developing. This study was restricted to examining the internal factors causing the decline in Indonesia palm oil exports. The purpose of this study is to analyze the production of palm oil and palm oil production of downstream products, as well as to analyze the factors that affect the demand for downstream palm oil industry in Indonesia for palm oil. This study uses time series data from 1991 to 2011 year. Indonesian palm oil demand model by palm oil downstream industry estimated by multiple linear regression models and estimation methods Ordinary Least Squares (OLS). Indonesian palm oil demand by downstream industries is derived demand (derived demand) of the company's profits that allegedly affected by input prices (real prices of domestic palm oil), output prices (real prices of downstream products) and total output (production of downstream products). The results showed a decrease in palm oil exports indicates that the domestic downstream industry began to flourish. Demand for palm oil in Indonesia's downstream industries significantly affected by the real price of inputs and the production of downstream products. In order to increase the production of cooking oil, margarine, soaps, and fatty acid and palm oil consumption by the downstream industry, the government should facilitate the loan interest rate subsidies and implementing tax holiday. The government should impose a tax or non-low duty on exports of palm oil downstream products.

Abstrak: Production of palm oil downstream products in Indonesia is still low compared to primary products, namely palm oil. demand for palm oil, margarine and soap increased every year. therefore, Indonesia needs to increase the production of palm oil derivative products, not only to meet consumer demand but also related to value-added. Relevant government policies in order to encourage the development of downstream palm oil industry, through the instrument of monetary policy interest rates can affect the production of palm oil derivative products are cooking oil, margarine and soap. The research objectives are (1) Analyzing the factors that influence the production of palm oil derivative products in Indonesia, cooking oil, margarine and soap. (2) Analyzing the impact of policy rate cuts on the production of cooking oil, margarine and soap in Indonesia. In order to address these objectives, a simultaneous equations model of derived from the production of palm oil in Indonesia is estimated by Two Stage Least Squares (2SLS) method. Domestic palm oil production is influenced significantly by the domestic price of cooking oil palm, palm oil price growth rate domestk, interest rate, and cooking oil production t-1. Domestic production of margarine significantly influenced by the production of margarine t-1. Production of domestic soap significantly influenced by the level of interest rates, the growth rate of industrial labor, and the production of soap domestuk t-1. in order to develop the production of palm oil derivatives suggested that the government should export oriented derivative products (cooking oil, margarine and soap) to increase foreign exchange and provision of low interest rates in order to increase investment in downstream industries.

Judul: Desain Sistem Transfer Energi Nirkabel Berbasiskan Tesla Coil
Abstrak: Tesla coil merupakan alat yang ditemukan oleh Nikola Tesla yang dapat mentransmisikan daya tanpa kabel dengan memanfaatkan prinsip induksi elektromagnetik. Pada penelitian ini dibuat sebuah prototype Tesla Coil dengan menggunakan transistor C1970 dan receiver menggunakan rangkaian LC. Identifikasi alat meliputi pengaruh daya input transmitter terhadap receiver, bentuk signal yang dipancarkan transmitter, pengaruh jarak transmitter dan receiver, nilai efisiensi serta efek alat terhadap perangkat lain. Hasil pengamatan menunjukkan bahwa semakin besar daya input maka semakin besar daya yang dipancarkan oleh transmitter. Bentuk sinyal yang dipancarkan oleh transmitter berupa gelombang listrik AC sinusoidal dengan frekuensi ~2.9 MHz. Semakin jauh jarak receiver terhadap transmitter maka semakin kecil amplitudo gelombang AC yang diterima oleh receiver, menyebabkan semakin kecil daya yang diterima oleh receiver. Adapun nilai efisiensi terbesar penangkapan daya oleh receiver yaitu sebesar 0.00516 % serta terdapat gangguan pada alat-alat tertentu seperti monitor komputer dan radio.
