Abstract

Indonesia is one of the countries that has the third-largest number of volcanoes in the world. Several volcanoes are still active today. This places Indonesia prone to disasters from the volcano. One of the volcanic activities is characterized by the release of poisonous gases such as CO2. At a certain threshold, this poisonous gas can kill living things. This research has designed a gas-producing engine as a replica of volcanic gas. This machine is very supportive of the development of volcanic gas research on a laboratory scale because it has the advantage of being lighter, simpler construction, cheaper and portable machine construction process. The gas produced by the machine is tested using the Dragger X-am 7000. , CO2, H2S, SO2, and CO. The results were obtained for 60 seconds of starting the engine, namely CH4 2.0% LEL, CO2 1.6% Vol, H2S 4.3 ppm, SO2 1.0 ppm, and CO 271 ppm.

Abstract

Material berdensitas energi elektrik tinggi sebagai bahan dielektrik kapasitor sangat diperlukan dalam industri bidang elektronika. Tujuan penelitian ini ialah mengkarakterisasi dan menganalisis polimer PVDF( Poly vinylidene fluorde) dan PVDF-HFP (Poly vinylidene fluoride-co-hexafluoropropene)  sebelum dan sesudah diimplan ion nitrogen. Metode penelitian yang dilakukan ialah menyiapkan sampel lapisan tipis Polimer PVDFdan PVDF-HFP kemudian diimplan menggunakan ion nitrogen pada dosis 4,69 x 1016 ion/cm2 hingga 1,41 x 1018 ion/cm2 pada energi 10 keV. Selanjutnya nilai kapasitansi, faktor disipasi dan kekuatan dielektrik sampel dikarakterisasi menggunakan LCR meter GW-Instek 800. Morfologi dan ikatan struktur dari sampel dikarakterisasi menggunakan SEM dan FTIR. Hasil percobaan menunjukkan bahwa terjadi peningkatan nilai kapasitansi sebesar 4,3 kali pada polimer PVDF dan 1,4 kali pada polimer PVDF-HPF. Peningkatan nilai kapasitansi disebabkan bertambahnya ikatan rangkap C=C pada PVDF dan PVDF-HFP yang diimplan ion nitrogen. Hal tersebut dibuktikan dari hasil karakterisasi FTIR dan SEM. Namun demikian nilai kekuatan dielektrik mengalami penurunan akibat semakin konduktifnya polimer PVDF dan PVDF-HPF. Untuk sampel PVDF ada kapasitansi optimum dicapai pada dosis 9,38 x 1017 ion/cm2 sedangkan untuk sampel PVDF-HFP diatas dosis tersebut memperlihatkan gejala saturasi. Nilai kapasitansi optimal diperoleh berturut-turut sebesar 0,089483 nF, faktor disipasi 0,129613 % pada polimer PVDF dan 0,134889 nF, faktor disipasi 0,09784 % untuk polimer PVDF-HFP.

Abstract

Water is a vital human need that must be met for human survival and carrying out daily activities. However, the condition of natural resources in each region is different, not all regions have sufficient water availability. One of them is in Serut, Gunungkidul which is an area with hilly geography. During the dry season, clean water sources in Serut District become scarce and very limited. Therefore, the Serut District Government cooperates with the Community Self-Help Group (KKM Tirta Abadi Jaya) to drill deep wells to distribute water to residents. However, along the way, the operational costs are very large, especially for water pump electric pulses. In addition, the geographical condition of Serut which is hilly and has many trees causes frequent power outages, especially in extreme weather. This affects the resistance of the water pump because it is often on and off. The power outage can also stop the distribution of water to residents. This community service provides a solution to these problems, namely the installation of solar electricity generation. With this solar electricity generation, it can reduce the operational costs of electric pulses. In addition, using solar electricity generation can increase the durability of the tool because there is no on-off. Residents also still have their water needs met even though there is a power outage because the electricity needs for water pumps are supplied from solar electricity generation.
