This research aims to study the mechanics (strength) properties of iron ore briquettes. Iron ore briquettes are made using the hot briquetted iron method (HBI). HBI is a briquette after reduction directly and pressed at a temperature above 650 ⁰C and has more density than 5000 kg/m3. The specimens used were iron ore briquettes made of the composition of iron ore, coal, and adhesives. The composition of the briquettes is 55: 40: 5, 65: 30: 5, 75: 20: 5, 85:10: 5 and the reduction temperature is 750⁰C,850⁰C,950⁰C and 1050⁰C. There are 16 briquett specimens. After the briquettes are made, the briquettes are reduced using a reduction blast furnance which is fuel by LPG and CO2 gas. When the mass of briquette is no longer decrease ore the time (reach steady state condition) the briquettes take out from the blast furnance for press. Pressing is carried out in hot briquettes conditions and the press load is 15 tons. The results obtained from testing the I-Type Tumbler Test have more small paricle ruptures because the briquettes have lost their adhesive during the reduction process and coal does not affect the strength of the HBI briquettes. After being reduced briquettes are given more adhesive so that briquettes can be tested again. Iron ore briquettes after reduction are stroger than those before reduction. In the variation 85:10:5 obtained from testing I-Type Tumbler Test iron ore briquettes test after reduction has a number of particle small rupture 0,21% while iron ore briquettes before reduction of 3,35%.

Air conditioning and heat pump systems can use the ground as a medium to dump or absorb heat energy to increase efficiencies. As compared to the air, the ground has lower temperature in the summer and higher in the winter. In this research, the vertical U tube underground heat exchanger that can be used to harvest geothermal energy, has been modeled by using two dimensional finite difference methods. The model is not only able to estimate the water temperatures out of vertical U tube underground heat exchanger, but also capable of calculating the temperature profile change of surrounding soil under various water entering heat exchanger and weather conditions. The heat transfer process between the underground heat exchanger and soil has been investigated and profiles of soil and water temperatures are presented.

The province of Aceh is known for its coastal area which has enormous potential for the development of aquaculture of aquatic biota, both freshwater and saltwater communities. The potential for production from freshwater and saltwater fish businesses will be even more exciting in 2021. This is because the amount of fish consumption per capita of the world's population reaches 19.6 kg per year. This value is obtained from the results of estimates through the United Nations Food Agency in 2011. For this matter, various matters relating to the cultivation system must be prepared, starting from the stage of the enlargement process to the stage of feeding or baiting which is more regular and has precise calculations. The purpose of making this automatic feed machine product is to make it easier for aquatic biota cultivators the process of feeding aquatic biota in ponds and ponds through the development of an automatic feed distribution system equipped with systematic timing. With this equipment, the perpetrators of cultivating aquatic biota are able to provide feed easily and regularly so that it helps avoid aquatic biota experiencing a lack of feed which ends in death. The biggest benefit is that cultivators have time savings as well as labor cost savings. The results of this equipment manufacture in the form of a feed control system and feed spreader automatically assisted by the supply of solar power directly to the solar panel so that it is able to convert light energy and sunlight into electrical energy. The output of this product is expected to be able to provide the right solution to cultivators in increasing income and making it easier to use easy and efficient tools.

Aceh Province is an area surrounded by coasts which has great potential to develop marine product cultivation, one of which is seaweed. In line with the goal of the central government in 2018 stating its support for increaseing seaweed cultivation in Aceh Province. Meanwhile, the Ministry of Maritime Affairs and Fisheries' Directorate General of Cultivation stated that so far the seaweed industry and cultivation are still constrained by transportation problems for marketing. Based on the results of research in a number of regions in Indonesia, it is explained that the coastal area of Aceh is an area that has very good potential for the seaweed cultivation. This study focuses on the Glacilaria sp seaweed cultivation due to its easiness to grow in community ponds. The drawback of this pond cultication method is the existence of predators that eat seaweed and the pond bottom mud that pollutes the seaweed. The application of floating house technology for glacilaria seaweed culture is seen as a solution for aforemention problems. This technology protects the seaweed from predators and the contamination of the seawee from mud pond. The proposed sea seaweed cultivation method is anticipated to offer better income and improve the quality of life of the community, especially in the the targeted area, Alue Naga. Regarding the current situation, Farmer in Alue Naga still practice the conventional method for cultivating the seaweed in the land pond. This regular method has the shortcoming in protecting the seeweed from the predators. In addition, due to the seaweed attached to the bottom of the pond, it causes the slow growth of seaweed. These circumstances cause the crops have lower quality, result in a hardly marketable product either for national or international markets. To cope with such conditions, an easy to use, reliable and safety floating house was proposed and built for the use of glacilaria seaweed culture. The community is also engaged in the workshop and construction of floating house for the glacilaria seaweed culture taught by staff of Cot Irieh Fiberlass workshop. This engagement aims to increase the insight and skill of the community regarding construction and maintenance of the glacilaria seaweed culture floating house. This study is fully supported by Syiah Kuala University Research and Community Service Institute through fostering the Alue Naga fishing community through direct application of technology.

Entering the economic era of free competition, various fishing technology supports have increased, but there are difficulties in terms of the availability of fish storage media in the long term. Products circulating today are not able to last long and are easily damaged. The problem that occurs is that the storage media does not have long durability against age, impact, maintenance and ease of repair. The composite material application applies the hand lay up method. The work process is carried out in stages starting from making patterns, molds to finished products. The material used consists of thermosetting resin, supported by reinforcing fiber consisting of E-glass fiber and organic ramie fiber. The combination of the two is called a hybrid material. The stages of this process are carried out efficiently and carefully until the final target is met for a quality Ice cool box product. Ice cool box composite as a direct application of campus research results so that it can be used for the needs of Acehnese fishermen.
