Abstract

Mekanisme produksi produk halal telah diatur UU No. 33 tahun 2014 tentang Jaminan Produk Halal. Keberadaan sertifikat halal memberikan rasa aman bagi konsumen terutama bagi keluarga muslim. Pentingnya mengkonsumsi produk halal harus ditekankan sejak dini. Pengetahuan tentang produk halal harus diajarkan pada siswa-siswi sekolah dasar. Surabaya memiliki 650 sekolah dasar yang menyebar merata dimana kecamatan Rungkut memiliki 24 sekolah dasar. Mitra kami adalah SDN Penjaringansari 2, SDN Rungkut Kidul 1 dan SDN Kedung Baruk Surabaya. Setiap sekolah dasar memiliki beberapa kantin yang menjual produk makanan dan minuman. Namun, kantin tersebut belum bisa menjamin bahwa produk makanan dan minuman yang dijual belum memiliki sertifikat halal. Selain itu, konsep kantin masih bersifat konvensional yang berfungsi jual beli. Oleh karena itu, kegiatan pengabdian masyarakat ini bertujuan untuk membangun kantin kejujuran yang berbasis halal. Dengan kehadiran kantin kejujuran berbasis halal pada sekolah dasar masing-masing mendukung Pendidikan karakter integritas bermasyarakat serta menerapan gaya hidup halal berdasarkan syariat islam.

Abstract

Carbon dioxide is an acid gas that can be harmful impurity especially in the chemical industry. Various processes have been developed to reduce the CO2 from the gas stream. Chemical absorption is the most economical method for CO2 separation. One of the processes that is widely used in industries is Benfield process with K2CO3 (potassium carbonate) as a solvent and amine as a promotor. In this study, MDEA (Methyldiethanolamine) is used as a promotor. As a reference for designing CO2 absorption/stripping packed column in industries, gas-liquid equilibrium data were required. The objective of this study is to predict the gas-liquid equilibria of CO2-K2CO3-MDEA-H2O system at 30oC and atmospheric pressure with 30% K2CO3 and variation of weight percent of MDEA 2, 5, 8, and 10%. The model used in this study is an electrolyte UNIQUAC. The simulation was conducted using Matlab programming. The deviation of predicted CO2 partial pressure with the experimental data is 14.85%. The energy interaction parameters of electrolyte UNIQUAC model were obtained from fitting with the experimental data by Least Square method. The results of this study represented that with increasing CO2 partial pressure, CO2 loading increased, and also at the same partial pressure of CO2, CO2 loading increased with the increase of weight percent of MDEA
