Nafion is a type of perfluorosulfonic acid membranes, are widely used in fuel cell technology and exhibit several disadvantages such as expensive, have a limited working temperature range and high methanol crossover. This study aims to produce an electrolyte new polymer membrane from polyeugenol sulfonated (PET) and a review of the membrane properties was carried out on the basis of Water Contact Angle (Â°), Water Uptake (%), Methanol Uptake (%), Swelling ratio (%), IEC (ion exchange capacity). Analysis of DMFC membrane performance has an optimal proton conductivity of 0.0009 S.cm-1 and methanol permeability of 23.5.10-7 cm2.s-1 with a PET composition of 27% (w/w). Â

Mitra 1 (Purnama Advertising) is a printing business engaged in printing and graphic design, owned by Mr. Purnomo. Business location Purnama Advertising is very strategic close to the highway, due to many people skipped. Mitra 2 (Smart Jaya) owned by Mr. Hidayat handles a very simple print design. Smart Jaya business location is very strategic close to the school. The problems faced by Partners 1 and Partner 2 are constrained in the field of online marketing, due to the limited cost of the Partners. The purpose of the devotion activity is to develop an independent printing business and have a broad insight on print design and graphic design. The solutions offered from the devotion activities are providing printing machines and hot press machines, mentoring media marketing, production management and marketing training. The outcomes of the IbM program are scientific publications in ISSN Journals, national seminar publications, and online promotional media.

In the millennial era 4.0, the growth of the home industry is growing more rapidly with the development of information technology, thus making needs increase and create new business opportunities. One of the new business opportunities is the krawu rice business. Krawu rice is a typical food from Gresik Regency. The krawu rice home industry is a partner of a community service activity named Nasi Krawu Buk Tiban. The problem that occurs in the community service partners is the marketing of krawu rice that is still around the Nasi Krawu Buk Tiban environment and marketing through the internet media. The method used is to provide training in the form of online media marketing and social media assistance. The result of community service activities can increase krawu rice revenue turnover, can operate and promote krawu rice marketing through online media and social media.

Penelitian ini dilatarbelakangi oleh kurangnya pemahaman pelajar pada materi Termokimia yang bersifat kompleks dan abstrak, sehingga dilakukan penelitian ini sebagai bentuk penerapan materi Termokimia secara nyata. Tujuan dari penelitian ini antara lain untuk mengetahui pengaruh suhu terhadap penentuan kapasitas panas kalorimeter serta korelasi antara konsentrasi NaOH dengan panas pelarutan dan panas netralisasi yang dihasilkan. Metode yang digunakan pada penelitian ini yaitu dilakukan penelitian eksperimental dengan melakukan tiga kali proses secara berturut-turut menggunakan alat kalorimeter sederhana dengan variabel yang berbeda pada setiap proses. Hasil penelitian yang telah dilakukan menunjukkan bahwa nilai kapasitas panas kalorimeter yang dihasilkan sebesar -4692,7 J pada suhu akhir campuran 54°C. Nilai penentuan panas pelarutan terbesar yang dihasilkan sebesar -3865,214 dengan massa NaOH 1 gram, sedangkan nilai panas pelarutan terkecil yang dihasilkan sebesar -3914,694 J dengan massa NaOH 10 gram. Nilai penentuan panas netralisasi terbesar pada konsentrasi 2 M yaitu sebesar -4561,458 J, sedangkan nilai panas netralisasi terkecil yang dihasilkan pada konsentrasi 0,1 M yaitu sebesar -4691,877 J.Kata kunci: termokimia, kalorimeter, panas reaksi, panas pelarutan, panas netralisasi.

A heat exchanger or commonly referred to as a heat exchanger is a tool that is commonly used in the industrial world. The function of this tool is to cool down a fluid. There are various types of heat exchangers, including shell and tube. The purpose of this research is to design a heat exchanger that is good and correct and has a fairly high effectiveness in accordance with the existing heat exchanger design rules. The object of this research is a heat exchanger with a size of OD in, 16 BWG with stainless steel material which has a counter current type which is used to cool the type of air at a temperature of 80°C to 60°C with the help of an air type fluid also at a temperature of 60°C. 30°C. The effectiveness of the tool is quite large, namely 88.7%.

The liquid waste of the food industry has recently increased. Therefore, when it is discharged into the waters, it will cause turbidity and can damage the ecosystem inside. One of the wastewater treatment techniques is absorption using biosorbents, one of which is made from coconut fiber to reduce the color intensity of the liquid waste. The purpose of this study was to determine the effects of the coconut fiber biosorbent on the color intensity, COD, and pH of the liquid waste of the food industry. In this research, the coconut fiber was delignified with a 2 M NaOH solution and then activated with a 3 N solution. The research variables consisted of the weight percentages of biosorbent by 1%, 2%, 3%, 4%, and 5%, and the contact time of 30 and 60 minutes with shaker stirring. Meanwhile, the most optimum results in COD removal happened at the addition of 4% for 60 minutes, from the initial COD of 1179 mg/L O2 to 780 mg/L O2 within the removal of 26.5%. The highest pH removal of 6.98 occurred in the variable addition of 1% for 30 minutes, whereas the lowest pH removal of 6.5
