Abstract

Dalam aplikasinya komponen harus mempunyai sifat mekanis yang keras, agar komponen tidak mudah rusak dan umur dari komponen tersebut bisa lebih panjang. Kekerasan dipengaruhi oleh strukturmikro yang ada dalam bahan. Dan untuk memperoleh sifat mekanik yang keras maka harus merubah strukturmikro dengan melalui proses perlakuan panas yang diberikan terhadap bahan tersebut. Bahan yang digunakan adalah komposit alumunium 2075 - abu dasar batubara. Tujuan dari penelitihan untuk mengetahui pengaruh variasi temperatur aging 100°C, 125°C, 150°C dan waktu aging 45 menit, 60 menit, dan 75 menit pada perlakuan panas T6 terhadap kekerasan dan strukturmikro. Metode penelitian yang digunakan adalah metode kuantitatif dengan pengujian dan pengamatan di laboratorium. Dari hasil analisa yang dilakukan, pada rentang temperatur dan waktu aging yang diterapkan, bahwa semakin tinggi temperatur dan waktu aging kekerasan yang diperoleh semakin tinggi dan ukuran butir yang dihasilkan semakin kecil, hal ini disbabkan oleh jumlah presipitat yang diperoleh semakin banyah sehingga menghambat pertumbuhan butir. Nilai kekerasan terendah terletak pada temperatur aging 100°C dengan waktu aging 45 menit menghasilkan nilai kekerasan 45HRA. Meningkatnya temperatur aging dan waktu aging menyebabkan ukuran butir semakin kecil. Butiran terkecil terdapat pada temperatur aging 150°C dengan waktu aging 75 menit dengan diameter rata-rata 88,714μm. Butiran terbesar terdapat pada temperatur aging 100°C dengan waktu aging 45 menit dengan diameter rata-rata 137,756μm.

Abstract. Almost every year during the rainy season, landslides continue to haunt the villagers Wonodadi Kulon Ngadirojo Pacitan. Biggest landslides occurred in the past 2009 years. At least, dozens of houses were severely damaged, at least 13 cows are victims and impaired access road connecting the village to the other. Within four (4) years after the great disaster, there has been no attempt to anticipate or prevent the occurrence of landslides. Wonodadi Kulon village at an altitude of 80-500 meters above sea level to be exact in South Kendeng Mountains about 55 miles from downtown Pacitan. Its area is hilly with a slope of 68 degrees. From the survey conducted disaster seems to be increasingly threatened due to changes in land use that was originally in the form of community forest turned into farmland. Land use as agricultural land utilize a relatively steep slope, so that erosion will often occur in the form of erosion gully and soil mass movement (landslides). Erosion at this next level causing a big impact for environmental damage, such as flash floods. Public knowledge about forest conservation and water resources is still low proven that many people who are looking for firewood in the forest. Data from the local village administration mentioned critical land area of 102 hectares land area of 309.30 ha mild erosion; a land area of 410.53 ha of erosion was severe erosion and a land area of 10 ha.Keywords: disaster, landslide

Abstract

Desa Papungan Kecamatan Kanigoro Kabupaten Blitar merupakan desa yang memiliki ikan yang khas yaitu ikan mujair. Ikan mujair oleh masyarakat biasanya hanya dikonsumsi dengan cara digoreng atau dibakar saja. Karakteristik ikan yang mudah membusuk menyebabkan masyarakat harus segera menjual hasilnya dalam keadaan hidup atau segar saat dipanen. Keadaan tersebut dapat diatasi dengan melakukan proses pengolahan hasil ikan yang berlebih agar daya awetnya meningkat. Dalam usaha meningkatkan daya awet dan meningkatkan pendapatan, kendala yang dihadapi masyarakat adalah rendahnya pengetahuan dan ketrampilan dalam mengolah pangan asal ikan, terutama ikan mujair. Tujuan dari pengabdian masyarakat ini adalah untuk memberikan pelatihan dan pendampingan kepada masyarakat yang membudidayakan ikan Mujair agar bisa mengolah hasil ikan menjadi produk lain yang mudah dilakukan serta diminati masyarakat. Metode yang digunakan dalam pengabdian ini adalah memberikan pelatihan dan pendampingan pengolahan ikan menjadi abon ikan dan ikan krispi. Hasil dari pengabdian masyarakat ini adalah memfasilitasi teknologi tepat guna berupa peralatan serta pelatihan dan pendampingan sehingga dapat meningkatkan ketrampilan serta pendapatan masyarakat desa Papungan, khususnya masyarakat pembudidaya ikan mujair.
