Solar energy is the energy that is most easily obtained in the conditions of our country which is in an area that is crossed by the equator. Energy that can be in the form of sunlight and heat from the sun can certainly be used as alternative energy to produce electrical energy. One technology that is able to utilize solar thermal energy is a solar parabolic trough system as a solar thermal collector. From the heat source produced, it is expected to be able to produce electrical energy generated by thermoelectric, where the thermoelectric heat side is obtained from the heat source in the solar parabolic trough. By conducting experiments to manufacture a power plant that utilizes a solar parabolic trough which is integrated with a thermoelectric type TEG-SP1848-27145SA as many as seven pieces, then the experimental data is taken from the device capable of producing electrical energy output. The output of electrical energy in the form of electrical voltage produced is strongly influenced by the difference in temperature on the hot and cold side of the thermoelectric, the greater the temperature difference, the greater the energy output that can be generated. From the experimental results, the highest temperature difference produced is 20.7oC with a current value of 85.93 mA and a voltage of 2.51 volts in the direction facing north, and the highest temperature difference produced is 11.5oC with a current value of 77.63 mA and a voltage of 2.15 volts in the direction facing east to west.

Fused Deposition Method (FDM) is one of the additive manufacturing methods or methods used by 3D printers. This FDM technology can produce models with a fairly good level of accuracy and strength. However, until now information about the magnitude of the value of accuracy, and the value of strength is very minimal. Because of this, it is necessary to do a test to determine the strength value of the specimens produced using 3D technology printing. The tests carried out aim to obtain settings optimal parameters on a 3D printer using PLA material which is measured by the magnitude of the tensile strength value of the resulting product. The test is carried out by measuring the amount of stress that occurs when the tensile test is carried out. The test was carried out using 81 samples that were printed using the parameters of infill print speed, fill density, extruder temperature, and layer height. Based on the test results, the highest stress value is 1.092 N/m2 with a combination of parameters infill print speed 60 mm/s, fill density 40%, extruder temperature 200oC, and layer height 0.1 mm. The results of the analysis show that the parameter extruder temperature has the greatest influence on the magnitude of the tensile test value, while the layer height parameter has the smallest effect on the value of the test specimen.

Alat pengering buah pinang menggunakan metode pembakaran biomassa merupakan salah satu metode pengeringan yang ditawarkan dalam proses pengeringan buah pinang selain menggunakan tenaga matahari.Selama ini tenaga matahari dianggap masih kurang efektif dalam proses pengeringan dikarenakan lamanya waktu pengeringan yang bisa memakan waktu sampai 14 hari dan juga sangat bergantung pada kondisi cuaca yang sering kali berubah-ubah. Proses pengeringan pinang sangat bergantung pada kondisi suhu lingkungan dimana suhu ideal dalam proses pengeringan buah pinang berkisar antara 350C-450C dalam kondisi panas matahari ,sedangkan menggunakan alat pengering pinang suhu optimal yang dicapai berkisar antara 65oC-70oC. Buah pinang yang digunakan adalah buah pinang yang telah matang dengan indikator persentase kadar air di atas 65% sedangkan untuk persentase buah pinang kering ialah dibawah 11% kadar air yang terkandung dalam buah pinang tersebut. Metode pembakaran biomassa pada penelitian ini ialah menggunakan kayu api, sekam dan tandan kosong. Prinsip kerja alat ini dengan memanfaatkan pembakaran dari pipa yang berada di ruang pembakaran dimana pipa akan dipanaskan sehingga tempratur pada pipa akan naik, kemudian udara akan masuk melalui dorongan blower yang terdapat pada sisi luar pipa tersebut, udara akan memasuki pipa kemudian temperatur udara akan naik mengikuti temperatur lingkungan lalu udara akan masuk ke sistem pengering atau oven sehingga proses pengeringan berjalan. Tujuan dari penelitian ini adalah mempercepat proses pengeringan buah pinang dimana metode pengeringan menggunakan matahari membutuhkan waktu sekitar 14 hari, sedangkan lama pengeringan menggunakan alat pengering pinang ialah berkisar 5-10 hari sehingga dapat menghemat waktu pengeringan. Adapun hasil yang didapatkan dari proses pengeringan ini dimana dalam metode pembakaran biomassa dibagi menjadi 3 bahan bakar yaitu kayu api, sekam dan tandan kosong, didapatkan hasil bahwa lama pengeringan masing masing biomassa tersebut ialah 6 hari, 8 hari & 9 hari. Sedangkan untuk suhu pengeringan berturut turut ialah 65°C-70°C, 55°C-60°C & 45°C-50°C dan rata-rata hasil persentase pengeringan pinang ialah 10%, 10,3%, dan 10,7%. Lama pengeringan serta suhu maksimal yang dicapai sangat dipengaruhi oleh kualitas bahan bakar, semakin besar residu bahan bakar maka semakin rendah suhu maksimal dari pembakaran.
