Peningkatan Mesin Cetak dan Kekuatan Mekanik Batu Bata Press Menggunakan Mesin Cetak Kapasitas 1000 Buah/Jam pada Usaha Keluarga di Desa Kalipucang Kulon

Abstract

Kota Jepara salah satu kota dimana terdapat peluang usaha untuk memenuhi kebutuhan batubata. Sentra batu bata salah satunya berada di desa Kalipucang Kulon kecamatan Welahan. Dari kekuatan mekanik batu bata masih di bawah standar, densitas rendah, porositas tinggi dan warna merah. Batu bata mengandung pasir besi dan jenis tanah lempung merah. Usaha pembuatan batu bata di desa Kalipucang Kulon sebanyak 54 buah
yang terdaftar di kantor Kelurahan tahun 2015. Banyak terjadi permasalahan di mitra UK batu bata Kalipucang Kulon, antara lain, pembuatan batu bata konvesnsional dan ukuran batu bata tidak standar SNI. Aspek pemasaran masih menunggu pembeli, manajeman usaha bersifat kekeluargaan dan minimnya strategi pemasaran,modal terbatas, dan kurangnya informasi mengakses pinjaman modal. Tujuan pengabdian pada masyarakat Program Kemitraan Masyarakat (PKM) yaitu pembuatan mesin batu bata untuk meningkatkan produksi, pembuatan dan pemeliharaan website e-commerce untuk jual produk batu bata, manajemen usaha, strategi pemasaran, member informasi dan pendampingan mendapatkan modal usaha. Metode yang dipakai
adalah Workshop pembuatan dan pengoperasian mesin batu bata press sesuai standar SNI, pelatihan pembuatan dan pemeliharaan website e-commerce, memberikan pelatihan kewirausahaan, strategi pemasaran
produk, member informasi dan pendampingan untuk mendapatkan modal usaha,dan cara mengakses bantuan dana. Hasilnya dengan penerapan mesin batu bata press manpu meningkatkan 880% dibandingkan dengan
manual tenaga manusia. Kekuatan mekanik batu bata merah paling optimal dimiliki oleh komposisi campuran dengan kode B3 dengan kekuatan tekan 41.712 Kg/cm2 dan densitas 25,87 kg/m3. Peningkatan produksi dengan sifat mekanik batu bata press mampu meningkatkan pendapatan usaha keluarga dan kualitas batu bata.

Abstract

Jepara is one of town where there is a business opportunity to meet the need of bricks. The brick industry center is located in Kalipucang Kulon Village, Welahan Subdistrict. Seen from the mechanical power, the bricks are still below the standard, with low density, high porosity, and red in color. Bricks contain iron sand and are made of red clay soil. There are 54 registered business entities of bricks in Kalipucang Kulon Village in 2015.
