ABSTRAKTujuan kegiatan pengabdian ini adalah memberikan pelatihan produksi bersih dan manajemen usaha kepada kelompok usaha garam rakyat di Desa (Gampong) Kuala Idi Cut Kecamatan Darul Aman Kabupaten Aceh Timur. Prosedur pelaksanaan kegiatan teridiri dari; koordinasi kegiatan, sosialisasi, pelatihan, dan pendampingan. Kelompok masyarakat yang menjadi mitra pada kegiatan ini adalah Kelompok Putik Meulu.  Kelompok tersebut merupakan salah satu kelompok usaha garam rakyat, dengan anggota kelompok terdiri dari inong balee (janda) yang kehidupan ekonominya serba kekurangan. Kelompok ini telah menjalankan usahanya sejak tahun 2000 dan mampu memproduksi garam setiap hari sekitar 200 kilogram dari lima dapur dengan aset sekitar Rp 23.500.000. Hasil yang didapatkan, dengan adanya pelatihan produksi bersih garam dan berbagai macam manajemen pengelolaan usaha mampu merubah pola pikir mitra terkait dengan proses produksi garam. Dimana dapur garam dibuat permanen, diberi pagar keliling sehingga terhindar dari hewan yang masuk ke dapur garam. Dari aspek produksi, rata-rata produksi garam meningkat menjadi 90 kg/hari. Selain itu, garam yang dihasilkan juga berwarna putih dan bebas dari kotoran. Kesimpulan, dengan adanya pelatihan produksi bersih garam dan berbagai macam manajemen pengelolaan usaha diharapkan dapat membuka pola pikir petani garam mitra untuk menggunakan teknologi yang maju agar produktivitas garamnya meningkat.Kata kunci: garam rakyat, manajemen usaha, produksi bersih garam ABSTRACTThe purpose of this service activity is to provide training in clean production and business management to the people's salt business group in Kuala Idi Cut Village, Darul Aman Sub-District, East Aceh District. The procedure for implementing activities consists of; coordination of activities, socialization, training, and mentoring. The community group that is a partner in this activity is the Putik Meulu Group. The group is one of the people's salt business groups, with group members consisting of inong balee (widows) whose economic life is completely deprived. This group has been running its business since 2000 and is able to produce around 200 kilograms of salt every day from five kitchens with assets of around Rp 23,500,000. The results obtained, with training in clean salt production and various kinds of business management, are able to change the mindset of partners related to the salt production process. Where the salt kitchen is made permanent, it is given a fence around so as to avoid animals entering the salt kitchen. From the production aspect, the average salt production increased to 90 kg/day. In addition, the resulting salt is also white and free from impurities. In conclusion, with training in salt clean production and various kinds of business management, it is hoped that it will open the mindset of partner salt farmers to use advanced technology to increase their salt productivity.Keywords: people's salt, business management, clean salt production

Abstract Clean production is an activity to increase efforts to handle the waste of an industry. The purpose of this research is to identify the production process, to know the waste generated and to design a clean production that will reduce the waste generated. This research was conducted in a bakery located in Kota Baru, precisely on Jalan Prof. M. Yamin, Kota Baru, Pontianak. The research begins by identifying the general condition of the industry, then identifying the production process and problems in the industry and continuing with the analysis of appropriate clean production alternatives. The recommended clean production is the utilization of eggshell waste into organic fertilizer and handling plastic waste by giving the waste to the nearest waste bank. Keywords: bread industry, clean production, egg shell, minimation of waste Abstrak Produksi bersih adalah kegiatan untuk meningkatkan upaya penanganan limbah suatu industri. Tujuan penelitian ini adalah untuk mengidentifikasi proses produksi, mengetahui limbah yang dihasilkan dan rancangan produksi bersih yang akan mengurangi limbah yang dihasilkan. Penelitian ini dilaksanakan di toko roti yang berlokasi di Kota Baru, tepatnya di Jalan Prof. M. Yamin, Kota Baru, Pontianak. Penelitian diawali dengan mengidentifikasi kondisi umum industri, selanjutnya dilakukan identifikasi proses produksi dan masalah pada industri serta dilanjutkan dengan analisis alternatif produksi bersih yang tepat. Produksi bersih yang disarankan berupa pemanfaatan limbah kulit telur menjadi pupuk organik serta menangani limbah plastik dengan cara memberikan limbah tersebut ke bank sampah terdekat. Kata Kunci: industri roti, kulit telur, minimasi limbah, produksi bersih

Liquid Wastes

Tofu is an Indonesian traditional food which basically made from soybean. Tofu production process yields both solid and liquid wastes. If these are not handled properly, they may cause environmental contamination. Therefore, clean production planning needs to be conducted in order to bringout an environmental friendly industry for increasing productivity, increasing efficiency of raw materials and reducing wastes. This research was conducted at the tofu processing industry UD. Sumber Urip by collecting data through field observation, interview, questionnaire filling and 3 (three) stages of quick scan method which consists of identifing the production process of tofu based on the concept of clean production through the mass balance, analysing the alternative clean production improvements, observating and giving recommendations on waste utilization. The result shows that the tofu production process with clean production through the mass balance produced 210 kg dregs of tofu and 2.115,51 kg total liquid wastes. The research also proposes some alternative improvements of clean production as the implementation of good housekeeping principle, modification of funnel principle grinding, utilization of  personal protective equipment, and implementation of recovery and reduce principle. On the other hand the wastes generated from the tofu production process may be reproduced in to tempe gembus, animal feed, organic fertilizer, and biogas.

Chromium Salt

The pollution of chromium salt industry is increasingly serious in China and becomes a worldwide problem with the rapid development of chromium salt industry. Then a new clean production process with a high recovery rate of chromium and pollution-free was proposed according to the comprehensive summary of existing processes of basic chromium sulphate. Furthermore, a small amount of slag will be discharged in this short process with lower energy consuming. The design concept is also applicable to the preparation of other chromium salts products, which will eliminate the pollution of Cr6+ during the process of chromium salt production and be helpful to the comprehensive utilization of chromium salt. In addition, the guidance of scholar research and the broad application prospects of this work cannot be neglected.

Zeolite Production

The IGPC Engineering Department designed a basic technological project for an evaporation unit for detergent zeolite production at "Zeolite Mira", Mira, Italy. The evaporation unit was for a capacity of 15,000 t/h of evaporated water per hour from 26,000 t/h of 11 % NaOH solution.The gained product meets all quality regulation, as well as environmental regulations. The evaporation process is fully automatized, and the product has uniform quality. There is no waste material in detergent zeolite production, because all products with unsatisfactory quality are returned to the process. The production process can be controlled manually, which is necessary during start-up, and repairs. A fully closed cycle of filtrate was achieved by installing an evaporation unit. 11% NaOH solution is produced in detergent zeolite filtration, which is dangerous waste. It is evaporated to 26% NaOH solution and afterwards returned to the wet hydrate dissolution plant. In this way environmental protection is achieved, as well as a highly economical process.
