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: Effect of Black Campaign for Palm Oil (CPO) on Indonesian CPO Export Volume to Export Destination Countries
Abstrak: Kelapa sawit merupakan salah satu sub-sektor perkebunan Indonesia yang menjadi komoditas andalan ekspor non migas dengan bentuk produk olahan utamanya yaitu minyak sawit mentah atau Crude Palm Oil (CPO). Pertumbuhan produksi CPO Indonesia meningkat setiap tahunnya. Munculnya black campaign membuat ekspor CPO Indonesia menjadi terhambat. Penelitian ini bertujuan untuk menganalisis perkembangan volume ekspor CPO Indonesia dan menganalisis pengaruh black campaign CPO terhadap volume ekspor CPO Indonesia. Metode yang digunakan adalah analisis regresi data panel dalam kurun waktu 2000-2019 ke tiga negara tujuan ekspor yaitu Belanda, Spanyol, dan Italia. Hasil analisis regresi menunjukkan bahwa perkembangan volume ekspor CPO Indonesia berfluktuatif dan cenderung menurun. Kemudian variabel harga ekspor CPO Indonesia ke negara tujuan, harga internasional minyak kedelai, GDP riil per kapita negara importir, nilai tukar riil rupiah dan black campaign berpengaruh signifikan terhadap volume ekspor CPO Indonesia. Sedangkan variabel harga internasional CPO di pasar dunia tidak berpengaruh signifikan terhadap volume ekspor CPO Indonesia., Palm oil in the form of Crude Palm Oil, is one of Indonesian main export commodities. Indonesian CPO production growth is increasing every year, and yet the emergence of a black campaign has hampered Indonesia's CPO exports. This study aims to analyze the dynamic of Indonesian CPO export volume and analyze the effect of the CPO black campaign on Indonesian CPO export volume. Panel data regression analysis for the period of 2000-2019 to three export destination countries, The Netherlands, Spain, and Italy, shows that the development of Indonesian CPO export volume fluctuates and tends to decline. Then variables of Indonesian CPO export prices to destination countries, soybean oil international prices, real GDP per capita of importing countries, real rupiah exchange rates and black campaigns, have a significant effect on Indonesia's CPO export volume. Meanwhile, the international price of CPO in the world market has no significant effect on the volume of Indonesian CPO exports.

Judul: Rancang Bangun Alat Pengukur Intensitas Hujan Dengan Metode Jungkat-Jungkit Berbasis Sensor Medan Magnet UGN3503.
Abstrak: This research has been done on making rain intensity gauge using a magnetic field sensor UGN3503. Sensor UGN3503 can detect the magnetic field on its surface. The sensor is placed above a seesaw that was inserted magnet. The magnet used is Neodymium magnet is a type of permanent magnet with stongest magnetic field compared to other types of fixed magnetic field magnets. When the seesaw discards rainwater, the distance between sensor and magnet is closer and causing the keluaran voltage of the sensor increases. The keluaran voltage of the sensor is compared with a reference voltage by the comparator so that the sensor keluaran data is in digital form and ready to be processed. As the processing and sending of data used ATmega16 microcontroller, microcontroller take sensor data once every 100 ms and display data to the LCD (Liquid Crystal Display) 16x2. Every 30 minutes the data is processed into the rain intensity is then stored into a computer.
