The method of catching fish carried out by traditional fishermen in "fisherman-cage" still uses petromax lamps with kerosene or lamps from generators that run on diesel fuel. These situations could cause oil spills that pollute the environment and are prone to fires. This community service program introduces a new energy source, by designing a solar-based lighting system (PLTS), where sunlight is converted into electric current and stored in batteries as a backup current at night. In this design, fishermen can optimize lighting by adjusting the position of the lamp according to the sea level at high and low tide to attract plankton and fish to enter the cage net. The design of the prototype has been tested in the TI-MR ITEBA laboratory with very satisfactory results, and then it was continued with serial production of 10 sets to be handed over to the fishing community. The fisherman directly recognized the success of the 10 sets of PLTS in increasing fish catches and getting environmentally friendly when the team visited the cage location

The high national demand for sugar makes Indonesia very dependent on imports of cane sugar. Alternative products are urgently needed to reduce dependence on imported cane sugar, and one product that has potential is sago sugar. Currently, sago sugar is starting to be developed, one of which is in Sungai Tohor Village, Tebing Tinggi Timur District, Meranti Islands Regency. The aim of the service is to identify the process of processing sago into sago sugar, provide knowledge about the enzymes ?-amylase and ?-glucoamylase and their applications, provide enzyme packages that act as a binder as one of the factors in making sugar, reactivate production, teach e-commerce promotion, and recommend suggestions regarding the development of sago sugar products. The method or approach used in this activity is a participatory approach. This approach is a practice of communicative, transactive, advocative and collaborative planning theories. In carrying out this service, it was carried out well, from the delivery of materials, procurement of enzyme packages, manufacturing processes, and making attractive sago sugar packaging. Delivery of service material is done online with several constraints of funds, time, distance, energy, and conditions that do not allow service members to go back and forth in one day or stay overnight in the area, and considering that the process of making sago sugar will also take a long time. The enzyme package is the biggest expense in this service, considering that the price of this enzyme is very expensive. Meanwhile, the process of making sago sugar takes a relatively long time, around 3 or 4 days. The use of the enzymes ?-amylase and ?-glucoamylase in the process of making sago starch into sago sugar among sago farmers in Meranti Islands Regency got good results in the form of understanding the manufacture and use of enzymes, providing enzyme packages to sago processing entrepreneurs, good sago sugar production results, and produce attractive packaging that can be profitable.

The Riau Islands region is one of the archipelago areas in Indonesia where most of the people depend on marine products, one of which is shellfish, which have various colors and beauty. In various regions, people have Using seashells to improve the quality of life. Shells can be used as building materials, collections, clothing, furniture decoration, and as souvenirs, both for functional purposes and interior decoration. The use of goods that are not economical but can produce high economic value is currently attracting the attention of craft market players. If made into crafts or souvenirs, seashells, which are a product of marine waste, can be very valuable. Various types of crafts are developing in today's society, one of which is crafts that use resin as the main material. The manufacturing process with this composite material can be carried out easily by all groups. This composite manufacturing training was given to the Family Welfare Empowerment (PKK) group in the Cipta Garden housing complex which is approximately 10 km from the ITEBA campus. This group actively gathers every month, but no productive activities are carried out. In principle, this activity provides knowledge and skills for this PKK group to be productive by producing various types of crafts with high selling value. So it is hoped that later it can become an idea for entrepreneurship
