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

Performance is the most important aspect in achieving goals with maximum results from the performance of a good team or individual company. And vice versa, failure to achieve the formulated goals is the result of inefficient team or individual performance. the influence of employee safety and health on employee performance greatly determines the company's progress, this is due to the maximum worker conditions that will affect the results of their performance. This research uses multiple linear regression method because it uses x and y variables. In the regression method we have to distribute questionnaires to the respondents we are aiming for. This calculation uses the Multiple Linear Regression method with employee performance as the dependent variable (Y) and employee health and safety as the influencing variable (X). From the results of multiple linear regression analysis, it was found that the variable Health (X1) did not affect employee performance (Y) and safety (X2) had a linear effect on employee performance (Y). With a linear result Y = 1.652 –0.120 x1 + 1.046 x2.

Abstract

Corn cobs contains 40-45% cellulose, 30-35% hemicellulose, and 10-20% lignin, while corn cobs ash contains more than 60% silica with small amounts of metal elements. Silica in corn cob powder can be isolated thermally and nonthermally. Nonthermally silica can be separated with HCl. This research was conducted to isolate silica from corncobs using HCl with variations in calcination temperature and holding time. The silica obtained was then characterized by bonding and its structure using infrared spectroscopy (FTIR). The steps taken were preparing the tools and materials, then preparing the corncob powder, and then preparing silica with HCL and FTIR, as well as data processing and analysis. This study concludes that corncob powder produces silica by isolating it using HCL at 70 ºC  for 3 hours and calcining at 800 ºC with a holding time of 4 hours. Based on its FTIR characterization, samples soaked in HCL at 70 ºC  resulted in absorption caused by several factors, including single NH, CH, OH, triple bonds, double bonds, and single bonds. This is reinforced by the FTIR results, where the peaks are in regions 1, 2, 3, and 4.
