Firstly global warming issue caused by greenhouse gas emissions (CO2) which comes from human activities. Along with increasing of daily need, that humans of activities food produce is also increase, include of tofu. Tofu is a traditional Indonesian specialty made from soybeans and used as a side dish. The purpose of this study was to determine the impact of global warming from tofu products on Mampang Prapatan's Small Tofu and Medium Enterprises. The method used in this study is the Life Cycle Assessment (LCA) method with the help of Simapro 8.4 software with a 1 kg tofu functional unit. The data collected in this study is the average data of tofu production for 3 months, namely January - March 2018. The LCA data in this study include the process of soybean cultivation, transportation processes for shipping soybeans, water, fuel wood, and electricity use. The limitations of this study are from cradle (soybean cultivation) to gate (tofu products).The results showed that UKM Mampang Prapatan has the potential impact of global warming with a value of 3.84 kg CO2-eq, while the value of global warming in the production process knows the scenario of wastewater treatment and the use of Liquefied Petroleum Gas (LPG) as fuel for boiling pulp 4.49 kg CO2-eq soybeans. Based on the results of this study, greenhouse gas (CO2) emissions are issued; the intervention that can be done is to optimize the use of raw materials for production to reduce the impact of CO2-eq kg global warming.

POTENSI PEMANFAATAN LIGNOSELULOSA PADA COIR DUST SEBAGAI PENYERAP TUMPAHAN MINYAK PADA AIR (POTENCY OF LIGNOCELLULOSE UTILIZATION FROM COIR DUST AS AN OIL SPILL SORBENT IN WATER) Vera Barlianti; Edi Iswanto Wiloso

Oil spill can contaminate the environment as a consequence of activities related to crud oil exploration, oil refinery, transportation, pipeline leaking, and industrial process. This research related with the characteristics of coir dust as oil sorbent material to remove all from water. Hydrophobycity is an important parameter that determines the effectiveness of the oil sorbent. Some treatments were done in this research to increase tho hydrophobycity of coir dust. Moreover, these treatments were expected to improve oil sorption capacity of coir dust. They are heating and acetylation process. The result showed both of heating and acetylation could increase hydrophobycity and oil sorption capacity onto coir dust.Keywords: coir dust, hydrophobic, oil sorption capacity, sorbent, lignocelluloseINTISARI Tumpahan minyak dapat mencemari lingkungan sebagai konsekuensi dari aktivitas- aktivitas eksplorasi minyak bumi, penghilangan minyak, kecelakaan transportasi, kebocoran pipa, dan proses industri. Penelitian ini berhubungan dengan karakteristik coir dust sebagai bahan penyerap (sorben) minyak untuk menyisihkan cemaran minyak dalam air. Hidrofobisitas (sifat tidak suka air) merupakan parameter penting yang menentukan efektivutas sorben tersebut. Pada penelitian ini dilakukan beberapa perlakuan, baik secara fisik maupun kimia untuk meningkatkan hidrofobisitas coir dust. Perlakuan-perlakuan yang dimaksud adalah pemanasan dan proses asetilasi. Hasil penelitian menunjukan bahwa proses pemanasan dan asetilasi dapat meningkatkan hidrofobisitas dan kapasitas penyerapan minyak pada coir dust.Kata kunci: coir dust, hidrofobik, kapasitas penyerapan minyak, sorben, lignoselulosa.

The Renewability Indicator and Cumulative Degree of Perfection for Gamboeng Tea; Part.2, Exergy Calculation of Tea Factory Teuku Beuna Bardant; Muthia Syafika Haq; Arief Ameir Rahman Setiawan; Sugeng Harianto; Joko Waluyo; Adhi Irianto Mastur; Annisa Dieni Lestari; Anny Sulaswatty; Sujarwo Sujarwo; Nino Rinaldi; Edi Iswanto Wiloso

Renewability Indicator (RI) and Cumulative Degree of Perfection (CDP) were used to observe sustainability of Gamboeng Tea. The assessment then compared with black tea process in Black Sea Region in Turkey from the previous study. Calculation of exergy for Gamboeng fresh tea leaf had already described in Part.1. Since the main process for both production was drying, then tropical humid climate in Gamboeng is the main challenge to increase efficiency, and thus, renewability. This second part described the significant improvement of renewability had applied in Gamboeng by using wood pellet in rotary pannier. Further recommended improvement were by installing better humidity detector and connected to the process control so the process can adapt the ambient change which the relative humidity can be varied from 65% and up to 92%.
