Abstract

High levels of crude fiber contained in tofu waste become a limiting factor for its use as a source of feed. The purpose of this research is to improve the quality of tofu waste as a source of feed through the ensilage  process using the Bacillus amyloliquefaciens bacteria. The design used was the Factorial Complete Random Design with two treatments, i.e. the Bacillus amyloliquefaciens concentration and fermentation time. This research used three Bacillus amyloliquefaciens concentrations, i.e. 5 %, 10 %, and 15 %, and six fermentation times, i.e. 2 days, 3 days, 4 days, 5 days, 6 days, and 7 days. Based on the analysis of variance, the treatment of Bacillus amyloliquefaciens concentration and fermentation time and their interaction had an effect on the level of crude fiber and the total silage acid of tofu waste (P<0.01), but did not have an effect on its water level (P>0.05). The greater the dose of Bacillus amyloliquefaciens inoculated on the tofu waste, the smaller the average value of its crude fiber; contrary to the total lactic acid produced. The best treatment was obtained at doses of Bacillus amyloliquefaciens of 15 % fermented for 5 days with an average of crude fiber level of 17.3 % and total acid average of 0.87 %, which means they meet the requirements of SNI (Indonesian National Standard) for the ideal total acid criteria, i.e. 0.5-2.0 %. A decline in the level of silage crude fiber of tofu waste reached 44 % compared to tofu waste raw material. Based on the organoleptic test, the silage resulting from the fermentation of Bacillus amyloliquefaciens with a 15 % dose had the best aroma, color and texture compared to doses of 5 % and 10 %.

Abstract

This study aims to identify the priority of the cleaner production implementation and integrate it in the design of a comprehensive environmental performance measurement system for natural rubber industry in Indonesia. Prioritizing the cleaner production on the production process of natural rubber is based on the case of 10 Indonesian crumb rubber companies using the Analytical Hierarchy Process. The comprehensive environmental performance measurement system in natural rubber industry, i.e. in crumb rubber industry, starts from the selection of key environmental performance indicators (KEPI) using the fuzzy independent preference evaluation method. The environmental performance measurement model is developed to assist users in evaluating the comprehensive environmental performance and condition of the key indicators. The weighting for each of the KEPI is performed by means of the expert choice software. The environmental performance measurement model is designed in the form of a environmental scorecard with traffic light facilities which can provide recommendations based on the performance achievement status of each KEPI. From the results of the model verification in the case of crumb rubber industry, several indicator statuses were found "not good", i.e. on the index of raw materials, solid waste load, water conservation, energy conservation, and environmental innovation indicators. The environmental performance ranking model is designed to evaluate the comprehensive environmental performance in different companies or at different assessment periods.

Abstract

Solusi pengolahan akhir pipa (end-of-pipe) disadari belum mampu memberikan jawaban yang memuaskan terhadap penanganan masalah pencemaran lingkungan. Saat ini sejumlah besar perusahaan di dunia sedang mengupayakan keuntungan melalui suatu pendekatan pencegahan lingkungan yang dikenal sebagai eko-efisiensi dan produksi bersih. Walaupun penerapan Produksi Bersih dapat dilakukan melalui cara-cara yang amat sederhana, namun pada kondisi tertentu kadang-kadang memerlukan perubahan yang radikal dan perlu keterlibatan manajemen perusahaan yang proaktif. Penelitian ini mencoba mengidentifikasi karakteristik dukungan organisasi terhadap upaya penerapan Produksi Bersih perusahaan pada kasus Perusahaan BUMN Pulp dan Kertas. Hallain yang coba diungkap adalah prasyarat keberhasilan implementasi Produksi Bersih berdasarkan persepsi anggota organisasi. Hasil analisis menunjukkan Tingkat Penerimaan Konsep Produksi Bersih secara positif dipengaruhi oleh pemahaman manfaat ekonomi, kebijakan strategis, dan gaya kepemimpinan; sedang mekanisma evaluasi dan sistem insentif perusahaan masih menjadi faktor penghambat dalam penerimaan konsep Produksi Bersih saat ini. Secara umum, kalangan anggota perusahaan menempatkan faktor dukungan finansial sebagai faktor paling esensial bagi keberhasilan implementasi Produksi Bersih. Namun kenyataan dari analisis regresi menunjukkan bahwa sistem insentif perusahaan justru menjadi faktor penghambat penerimaan konsep Produksi Bersih. Faktor lain yang juga dianggap esensial berturut-turut adalah keterlibatan pekerja, komitmenmanajemen, kemampuan karyawan, dan kebijakan strategis. Walaupun kebijakan strategis perusahaan telah mengakomodasikan kepentingan lingkungan, namun hal ini tidak didukung hingga pada tahap pelaksanaan. Hasil analisis memperlihatkan kebijakan strategis perusahaan masih menjadi faktor penghambat dalam pelaksanaan Produksi Bersih. Fenomena lain yang menarik adalah ternyata saat ini belum terbentuk budaya produksi bersih pada tatanan perusahaan, tim pengelola lingkungan yang profesional juga belum memberikan peran yang signifikan bagi penerimaan dan penerapan Produksi Bersih di perusahaan.

Abstract

Standar keamanan pangan pada sektor Usaha Mikro, Kecil, dan Menengah (UMKM) makanan di Indonesia masih tergolong rendah, termasuk UMKM pengolahan ikan rakyat. Produk pindang merupakan salah satu produk olahan ikan yang cukup popular di Provinsi Jawa Barat. Usaha yang umumnya dikelola oleh UMKM ini tampak sangat jauh dari prinsip higiene pangan. Infrastruktur yang dimiliki sangat minim dan sangat berpeluang menyebabkan kontaminasi silang. Tujuan penulisan ini adalah untuk memodelkan resiko keamanan pangan pada rantai produksi olahan pindang pada kasus UMKM pengolahan ikan rakyat. Tahapan pengembangan model resiko keamanan pangan pada usaha pemindangan ikan dimulai dari identifikasi resiko keamanan pangan pada rantai produksi, identifikasi prosedur dan standar keamanan pangan yang mampu meminimumkan bahaya keamanan pangan produk pindang, dan merancang model resiko keamanan pangan produk pindang. Ada empat titik kritis resiko kemanan pangan pada pemindangan ikan, yaitu resiko dari bahan baku, resiko dari proses persiapan bahan, resiko pada proses perebusan, dan resiko pada proses penirisan dan penanganan. Untuk mencapai keamanan pangan produk pindang, UMKM pengolahan ikan perlu menerapkan pre requisites atau persyaratan dasar Good Manufacturing Practises dan Good Hygiene Practices. Pre requisites adalah kelengkapan yang harus dipenuhi oleh perusahaan yang ingin menerapkan sistem manajemen keamanan pangan baik berbasis HACCP maupun ISO 22000.Kata Kunci: UMKM Pindang, Model Resiko Keamanan Pangan, Titik Kritis Resiko.
