Judul: The Impact of Biodiesel Policy on Indonesian CPO (Crude Palm Oil) Consumption
Abstrak: Indonesia merupakan eksportir CPO terbesar di dunia. Adanya black campaign melalui isu lingkungan dan sustainability yang dikeluarkan Uni Eropa menekan ekspor CPO Indonesia di pasar internasional. Isu tersebut memicu over supply pada CPO Indonesia ditengah produksi yang terus bertumbuh. Peran konsumsi domestik diperlukan dalam menyerap supply sehingga dapat menjaga kestabilan harga CPO. Pengembangan biodiesel yang menggunakan bahan baku CPO menjadi program yang cukup strategis dalam menghadapi masalah tersebut. Tujuan penelitian ini adalah untuk mengetahui pengaruh program biodiesel dan faktor lainnya yang berpengaruh terhadap konsumsi CPO Indonesia. Penelitian ini menggunakan data tahunan dari 1989 hingga 2019 yang dianalisis menggunakan ECM (Error Correction Model). Berdasarkan hasil penelitian, pada jangka panjang variabel yang signifikan adalah populasi penduduk, harga CPO domestik riil, harga CPO Internasional riil, dan Kebijakan Biodiesel B20 (20 persen kandungan CPO pada biodiesel. Pada jangka pendek variabel yang signifikan adalah harga CPO domestik riil., Indonesia is world biggest CPO exporter. European Union regulation that considered as black campaign holding down Indonesian CPO export trough enviromental and sustainablity issues. The black campaign that released within rapid growth of CPO production causes over supply in Indonesian CPO market. The role of domestic consumption is important in order to handle the situation and keeping the price stable. The development of biodiesel become strategic policy as this biofuel using CPO as raw material. This study aims to analyze biodiesel and other factor that affect Indonesia CPO Domestic Consumption. This study uses yearly data from 1989 to 2019 which analyzed using ECM (Error Correction Model). This study found that in the long run, the significant variable is Indonesia’s Population, real domestic CPO price, real international CPO price, dan B20 Mandatory Policy (20 percent of CPO blending in biodiesel). In the short run, the only significant variable is real domestic CPO price.

Judul: Analisis Dampak Black Campaign Minyak Kelapa Sawit (CPO) Terhadap Volume Ekspor CPO Indonesia
Abstrak: Indonesia is the biggest producer and exporters of Crude Palm Oil (CPO) in the world. Palm oil is a vegetable oil with the highest consumption rates in the world. However, in international trade, consumers who choose to buy CPO are sensitive to negative issues or black campaign. The purpose of this study is to analyze the development of Indonesia's CPO export volume demand and analyze the impact of CPO black campaign against Indonesian CPO export volume by using secondary data from 1996 to 2011 in the form of panel data. The results showed that the volume of Indonesian CPO exports to United States, Netherlands, England and Germany has fluctuated. Regression analysis showed that the real exchange rate of rupiah, real GDP per capita of the importing country, international soybean price, CPO export price and black campaign affect the volume of Indonesia's CPO export demand. While the international CPO prices do not affect the volume of CPO export to destination countries

Judul: Rancang Bangun Pendeteksi Otomatis Ketinggian Permukaan Air Berbasis Sensor Medan Magnet UGN3503
Abstrak: An automatic detector of water level with sensor UGN3505 as detector of changes water level has been successfully be made for this research. Sensor UGN3505 is a hall effect sensor which works based on the large magnetic fields on the surface. The output voltage generated by the sensor without the influence of a magnetic field is 2,525 volts, the output voltage is different than it should be 0.025 volts is 2.50. This shows that the sensor is not completely free from magnetic field sources, there is still the effect of the Earth's magnetic field to the sensor. Sensor output voltage will increase, with increasing magnetic field on the surface of the sensor. As the central data processing equipment, used microcontroller ATmega16. The input of microcontroller is the changes output voltage of sensor than has been converted into digital data (internal ADC ATmega16) caused the changes of magnetic field. The digital data are readable by microcontroller be processed and displayed in the 16x2 LCD, LED indicator and buzzer. Programs created using software tools CVAVR with C + + language.
