Judul: Studi Mikroenkapsulasi Minyak Ikan Hasil Samping Pengalengan Ikan Tuna (Tuna Precook Oil)
Abstrak: Asam lemak omega-3 merupakan asam lemak esensial yang banyak terdapat pada ikan laut dan hasil laut lainnya. Tuna precook oil yang dihasilkan dari limbah cair industri pengalengan ikan luna merupakan salah satu sumber asam lemak omega-3 yang masih terbatas pemanfaatannya. Hal ini disebabkan karena baunya amis dan stabililasnya rendah. Mikroenkapsulasi merupakan altematif untuk mencegah bau amis dan meningkatkan stabililas serta menghasilkan minyak ikan dalam bentuk tepung. Aplikasi a5am lemak omega-3 dalam bentuk tepung akan lebih mudah dan lebih luas.

Judul: Studi Mikroenkapsulasi dan Stabilitas Minyak Kaya Asam Lemak Omega-3 dari Limbah Minyak Pengalengan Ikan Tuna (Tuna Precook Oil)
Abstrak: Asam lemak omega-3 EPA (Eicosapentaenoic Acid) dan DHA (Docosahexaenoic Acid) memiliki peranan yang sangat penting terhadap kesehatan, seperti menurunkan resiko penyakit kardiovaskular, kanker, dan berpengaruh terhadap kadar lipida darah. Disamping itu DHA juga berperan dalam perkembangan otak dan retina manusia selama dalam kandungan dan pada saat bayi. Sampai sa at ini sumber asam lemak omega-3 EPA dan DHA yang potensial dan ekonomis adalah minyak ikan. Salah satu minyak ikan yang belum banyak dimanfaatkan adalah precook oil dari industri pengalengan ikan tuna. Namun penggunaan minyak ikan sebagai sumber as am lemak omega-3 memiliki beberapa kendala, diantaranya baunya yang amis, kandungan asam lemak omega-3 bervariasi, dan tidak stabil. Banyak usaha yang telah dilakukan untuk mengatasi hal ini, salah satunya adalah dengan proses mikroenkapsulasi.

Judul: Spatial Model of Developing Village Based on Road Network and Land Use in Brebes District
Abstrak: Brebes is a rural district dominated by agricultural areas. The area of Brebes Regency is 1,769.62 km2 consisting of 292 villages and 17 sub-districts. Brebes Regency is in the northern region of Central Java Province, borders West Java, and is traversed by the Pantura National Road and the Trans-Java toll road. Geographically, the location of Brebes Regency is strategic so that infrastructure development is expected to optimize geographical advantages and encourage socio-economic development. However, in fact the gross regional domestic product (GRDP) per capita in Brebes in 2022 is IDR 17.61 million lower than the average GRDP per capita in the former Pekalongan Residency districts (consisting of five districts namely Pekalongan, Tegal, Pemalang, Batang, and Brebes) amounting to IDR 22.02 million. The Human Development Index of Brebes is 67.03, the lowest in Central Java, and the poverty rate in 2022 is 16.05%, the third highest in Central Java. Another indicator in assessing the development of Brebes, according to its characteristics which are dominated by rural areas, is the Village Development Index (IDM). IDM is a village development assessment index compiled by the Ministry of Villages, Disadvantaged Regions and Transmigration. IDM is a com-posite index that assesses social resilience, economic resilience and environmental resilience. Brebes' IDM in 2022 is 0.6850 or on average they have developing village status. The value is below the Central Java’s IDM average (0.7118) and below the IDM average of the former Pekalongan Residency districts (0.6913). To overcome backwardness, it is necessary to study the spatial aspects of rural areas in Brebes Regency so that rural development can be in harmony with the spatial factors that most influence each village. The main objective of this research is to create modeling based on spatial factors in the form of road networks and land use on the level of village development in Brebes Regency. The method used is road network analysis and land use analysis, as well as regression analysis to determine the influence of the road network and land use on the IDM of Brebes Regency. The selected road network analysis is an analysis of road connectivity (alpha and beta indices), road density, and shortest route, while the land use analysis selected is an analysis of built-up land, regional compactness, and land use diversity. Both analyzes produce quantitative data which is used as an independent variable to assess village development based on IDM as the dependent variable. Correlation between variables was analyzed through geographically weighted regression (GWR) which was preceded by ordinary least squares (OLS) analysis accompanied by a com-parison of the two. The first stage of road network analysis produces an alpha index, beta index, and road network density level. The alpha index value in Brebes is in the range 0.370-0.856 with an average value of 0.455. This figure is still lower than the perfect score (α=1), which means that the road network in Brebes within the village area is not fully connected well. Meanwhile, the beta index value in Brebes is in the interval 1.682-1.944 with an average value of 1.792. This figure means that the road network
