The PEMFC systems are generally operated in acidic environment conditions. Consequently, the metal bipolar plate in the system can easily be corroded. Therefore, the PEMFC performance is decreased along with long-term operation. Based on this fact, a mitigation approach is needed to prevent the corrosion issue in the metal bipolar plate to maintain the PEMFC performance. This work tries to evaluate the corrosion rate of the aluminium bipolar plate before and after being deposited with D-galactose. The electrophoretic deposition (EPD) technique was used to deposit D-galactose on the aluminum surface. To evaluate the effect of D-galactose on preventing the corrosion rate, it was deposited on the surface of the aluminium (AA5052) bipolar plate. The EPD processes were performed by using a potensiodimic in 0.5 M H2SO4. The results show that the optimum EPD process condition was obtained at 0.5 g/l D-galactose for 20 minutes of electrophoretic deposition time. This work indicated that the D-galactose could reduce the corrosion rate of aluminium bipolar plate with an efficiency of 90.7%.

This community service is carried out in the context of foreign cooperation where the partner is Professor Dr. Yusliza Mohd Yusoff from Universiti Malaysia Terengganu (UMT). We carry out this community service activity with the theme "Counseling and Making Environmentally Friendly Cleaners Using Lime Extract In the Context of Improving the Welfare of Teachers and Preparing Independent Entrepreneurship for SMA-IT Students at the Riyadhussholihiin-Cimanuk- Pandegelang Islamic Boarding School.” The targets in this activity were teachers and students of class XII SMA-IT at the Riyadhussholihiin-Cimanuk-Pandegelang Islamic Boarding School. They were given training and directly practiced making eco-friendly cleaners using lily extract. The PPM team will also provide assistance until the product can actually be marketed. The initial target for this product is to be used alone and sold to the laundry unit at the Riyadhussholihiin Islamic Boarding school. The next target will be sold to people outside the Riyadhussholihiin Islamic Boarding School. Activities will begin in February 2023 (In Syaa Allah) and end in June or July 2023. However, assistance will continue to be carried out to maintain the continuity of these activities.Professor Dr. Yusliza Mohd Yusoff s as a partner will inspect the field directly or monitor through the Vicon Zoom Meeting. The results of these activities are in the form of increased welfare for teachers obtained from the sale of environmentally friendly cleaning products. Also for students after graduation they can do entrepreneurship to make these products, both students who continue their studies and those who do not continue their studies can still do entrepreneurship. Evaluation can be done by monitoring the location after the community service implementation period is over. Assistance will continue to be carried out to maintain the continuity of the production and sales process.

This community service partner is the Non-Governmental Organization (NGO) PERMAI in Penang. PERMAI members are generally Indonesian workers who work in Penang, some of whom work as home-based food traders. Around where he lives, traders produce waste, including organic waste from cooking activities and leftovers from selling vegetables and fruit. This organic waste rots easily if left alone, causing an unpleasant odor in the surrounding area and causing a smelly and unhealthy environment. One way to handle organic waste, especially rotten fruit and vegetables produced from household or restaurant waste, is by making liquid fertilizer. The implementation method used is two stages, namely: 1) preparation stage; production originating from appropriate technological equipment activities for making liquid fertilizer, discussions and sharing with team members, and 2) the stage of implementing community service at partner locations, distributing questionnaires before and after the exposure. The expected target in this community service activity is to increase the knowledge of the Indonesian working community in Pulau Pinang regarding how to make and the benefits of liquid fertilizer which can be made from everyday household vegetable and fruit waste.

Regarding providing energy, few sectors are as massive as the oil and gas business. One of the most crucial parts of oil and gas production is the distribution pipes or pipelines that transport the production fluids, which include oil and gas, from one distribution point to another. The corrosion of A316 material, which can lead to holes or pitting, and the damage it causes in most industrial operations, particularly in the oil and gas industry, has resulted in substantial losses at high prices over an extended period of time. In the study, we will quickly examine what corrosion is, the different kinds of corrosion, inhibitors, and how to assess the corrosion rate of A316 stainless steel in salt water. Analysis of the electrochemical corrosion rate of Inconel 600 nickel alloy and stainless steel 316L subjected to varying amounts of saltwater (freshwater, seawater, mixed water). Because chlorine speeds up corrosion, alloys like Inconel 600 and 316L undergo pitting corrosion. The molybdenum component gives 316 stainless steel its superior corrosion resistance. That's why it works well for gas and oil pipelines that go through saltwater. Nevertheless, materials exposed to maritime environments must have cathodic protection or coating to prolong their life and stop the pipe from continuously corroding.
