Abstract

Potensi alam unggulan yang terdapat di desa Rendeng adalah sector pertanian dan perindustrian. Lahan persawahan yang ada ditanami oleh tanaman pangan dan palawija seperti padi, jagung, kacang hijau, kedelai dan lain sebagainya. Sementara untuk sektor perindustrian, tanah di desa Rendeng sangat cocok untuk digunakan sebagai bahan dasar pembuatan gerabah sehingga mayoritas warga disini bekerja sebagai pengrajin gerabah. Dari banyaknya produksi gerabah yang dapat dibuat ternyata para pengrajin di desa Rendeng belum mempunyai legalitas atau badan hukum khususnya perkumpulan berbadan hukum dimana perkumpulan berbadan hukum tersebut memiliki peran penting dalam kemajuan para pengrajin gerabah itu sendiri sehingga menjadi suatu permasalahan yang akan ditindak lanjuti sebagai pengabdian masyarakat. Permasalahan ini muncul akibat banyaknya masyarakat yang kurang  faham atas pentingnya badan hukum suatu perkumpulan. Oleh karena itu tujuan dari pengabdian masyarakat ini adalah mendampingi para pengrajin gerabah untuk membentuk perkumpulan berbadan hukum. Metode yang digunakan ada 2 tahap, yaitu tahap persiapan dan tahap pelaksanaan. Pada tahap persiapan dimulai dengan mengadakan perkumpulan para pengrajin gerabah, pada tahapan pelaksanaan terdiri dari permohonan penggunaan nama perkumpulan, permohonan pengeluaran surat keterangan nama perkumpulan dan pengesahan badan hukum perkumpulan. Pengabdian masyarakat mengenai Pendirian badan hukum perkumpulan pengrajin gerabah di Desa Rendeng Kecamatan Malo Kabupaten Bojonegoro telah berhasil dilaksanakan yang dibuktikan dengan keluarnya Surat Keputusan Menteri Hukum dan Hak Asasi Manusia Republik Indonesia Nomor AHU-0009051.AH.01.07.Tahun 2019 tentang Pengesahan Pendirian Badan Hukum Perkumpulan Gerabah Rendeng Jaya.

Abstract

Noise is a very disturbing problem in residential, office, educational, industrial and other environments. Noise can be reduced by using materials that can dampen and absorb sound. The sound dampening materials that are widely used by the public generally use glasswool and rockwool, but they are expensive. The more expensive the price of goods including sound absorbers, the more alternatives are needed by utilizing materials derived from nature which are easy to obtain and cheaper, besides that by utilizing existing natural fibers it can also reduce waste in the surrounding community. One example of utilizing waste from natural fibers is making composites using coconut fiber and corn cobs. Composite materials made from coconut coir fiber and corn cob are alternative sound absorbing materials that are environmentally friendly, easily available and inexpensive. The aim of the research was to obtain an optimum composition ratio to produce composites as environmentally friendly sound absorbing materials, to determine the value of the sound absorption coefficient (α) from the manufacture of coco fiber and corn cob composites as noise dampening materials. From the research results it can be concluded that the sound dampening ability results show varying values ​​for each test specimen. The highest incoming sound/energy is 94.4 dB at a frequency of 500 Hz while the lowest incoming sound/energy is 44.14 dB at a frequency of 125 Hz. Meanwhile, the highest sound/absorbed energy (mean value) was 37.7 dB at a frequency of 750 Hz in sample C, while the lowest sound/absorbed energy was -6.16 dB at a frequency of 4000 Hz in sample A.   Keywords: composites, noise, sound absorbing materials
