Kualitas minyak pala ditentukan oleh kualitas pala dan penggunaan teknologi proses pemurnian yang digunakan. Teknik pengeringan untuk bahan baku dan proses penyulingan yang meliputi bahan ketel, sistem pendingin, dan desain ketel untuk penyulingan mempengaruhi hasil dan kualitas minyak atsiri yang dihasilkan. Boiler terbuat dari Stainless steel 304 dengan diameter 70 cm, panjang 120 cm, dan tebal pelat 3 mm. Boiler juga dilengkapi dengan system water tube untuk mempercepat pemanasan air. Tekanan berlebih dikendalikan oleh katup pengaman tekanan karena boiler ini dirancang dengan kapasitas tekanan 3 bar. Ketel terbuat dari Stainless steel 304 yang dilengkapi dengan keranjang bertingkat untuk memkasimalkan sirkulasi dan tekanan uap dalam ketel. Pipa kondensor yang berada dalam air pendingin menggunakan pipa aluminum untuk memaksimalkan proses kondensasi. Selama proses pemanasan air di dalam water tube terus terjadi peningkatan temperatur hingga 80 oC pada menit ke 90. Temperatur air yang dipompakan ke dalam boiler sudah mencapai 73 oC yang bersumber dari kondensor. Sejalan dengan peningkatan temperatur air di dalam kondensor, hal ini mengakibatkan kestabilan temperatur pada saat penambahan air dalam boiler. Rata-rata penurunan temperatur hanya 2,7 oC. Penggunaan air panas dari kondensor dapat meningkatkan efektifitas boiler untuk menghasilkan uap yang ditransfer ke ketel. Hal ini menyebabkan temperatur di ketel langsung stabil pada menit ke 90 dengan rata-rata temperatur sebesar 110 oC. Tempertur air yang dihasilkan oleh kondensor bertahan pada 84-85 oC. Kondisi ini diakibatkan oleh penambahan air ke dalam kondensor yang dilakukan setelah air dalam kondensor tersebut dipompa ke boiler. Tempertur air dalam kondensor ini selain dapat meningkatkan efektifitas boiler dan ketel tetap juga dapt menurunkan kemampuan pipa kondensor untuk merubah fase uap ke cair. Penggunaan cooling tower sangat dibutuhkan untuk dapat menstabilkan temperatur air dalam kondensor maksimal hingga 60-65 oC. Perbedaan tempertur boiler, ketel dan kondensor dimana temperatur air dalam kondensor masih terlalu tinggi (85 oC). Hal ini perlu treatment khusus untuk menjaga temperatur kondensor pada temperatur rendah agar proses perubahan fase uap ke cair dapat berlangsung secara optimal.

This paper provides survey results of an electricity system that has been carried out from isolated village of Alue Keujrun, South Aceh, Indonesia. The village has a central photovoltaic power plant and a micro hydro power plant. Various problems in the field such as operation errors, lack of maintenance of the electric power system, low voltage and frequency have been found. Power plant operators have also never received any formal training from any institution. The village is located next to the Kluet river which has a very large potential to become a hydrokinetic power plant energy source. Therefore the Kluet river flow velocity was also measured during the survey and described within this paper. Based on the interviews results with local operators, the village power plant does not have an operating permit. Thus, we consider that it is important to review the types of permits required to establish a power plant in Indonesia, including small-scale power plants.

The design of a two-row rice harvest machine that has a weight of 65.26 kg has been designed and has worked well with a harvest speed of 20.33 hours per hectare, but the optimization of battery power to drive an electric motor needs to be studied, because the time needed to charge a battery 12 volts 45 AH to the full using a 50 watt peak solar panel is 10.8 hours considered not yet effective, so in this study optimization was carried out using two solar panel units in a horizontal position and arranged in parallel on the mini rice harvesting machine. Measurement of the output current and voltage when connected and not connected to the battery will be measured to determine the electric current received by the battery from the solar panel. The results show that the measurement data that have been made are relatively fluctuating due to weather conditions, but in general it can be concluded that the average voltage of solar panels will rise to 80% if arranged in parallel using two solar panel units and if a series of two solar panels is connected to the battery, the voltage will drop by 25%. For the condition of electric current data using one solar panel will produce an average electric current of 18 mA and if using a series of two electric panels will rise an average of 3.8 times in conditions not connected to the battery. And if it is connected to a battery using two solar panels then the electric current will drop an average of 2.8 times Keywords— voltage, current, solar panel, harvesting machine
