The increased demand for high-quality coffee led to the need to evaluate coffee quality for market acceptance. Indonesia has Arabica, which has the potential for high selling value. Arabica coffee varieties, including Ateng, Lini S, and Sigararutang, affect the content of compounds in coffee beans, such as chlorogenic acid, caffeine, melanoidin, sucrose, and protein. The objective of this study was to analyze the impact of Arabica coffee varieties on the compound composition and flavor characteristics of coffee. The UV-Vis spectrophotometric methods were used to determine the quantity of chlorogenic acid, caffeine, melanoidin, sucrose, and protein in different Arabica coffee varietals. The study revealed that the content of these compounds differed among the varieties. The Lini S variety had the highest chlorogenic acid and caffeine content, while the Ateng variety had the highest melanoidin, sucrose, and protein content. The varying levels of chlorogenic acid and caffeine in coffee significantly impact its flavor, resulting in a unique sour and bitter taste in coffee brew. Melanoidin, a high-molecular-weight brown compound, contributes to the malty flavor of coffee, along with sweet, nutty, caramel, and spice notes. Sucrose adds a sweet hint to coffee brew, while protein has a relatively minimal influence on coffee flavor.

Indonesia is an archipelago country that has the longest coastline after Canada (UNCLOS). Banyuwangi District is a coastal area in Northern Java, which has a very dynamic development because of its location of the capital city that located along the coastal area. The purpose of this study is to assess the degree of coastal vulnerability in Banyuwangi District with the higher level of development. The CVI method (Coastal Vulnarability Index) of evisien sting is used to assess vulnerability. The coastal vulnerability is very low over 8 km, with a 15.4% of coastal length of Banyuwangi District. Low vulnerability occurs in areas that are located in areas close to settlements area, with beaches already experiencing human intervention. The low category is about 12 km long, reaching 23.3% of the existing coastal length in Banyuwangi District. The middle category is about 16 km, equivalent to 30.8% of shoreline. While the high category is about 10 km, equivalent to 19.2% of coastal length. The highest category has a length of 6 km, equivalent to 11.5% of the coastal area of Banyuwangi district.

Carcass characteristics are one of the factors that significantly impact the quality of meat. Genetic improvement in carcass characteristics is required to encourage interest among consumers. The objective of this study was to discover the presence of the SLC25A30 gene polymorphism at SNP g.15912281 A>T and its potential association with carcass characteristics in Indonesian sheep. The study used 153 rams, consisting of 87 Javanese thin-tail sheep, 20 Javanese fat-tail sheep, 10 Garut composite sheep, 10 Compass Agrinak sheep, 10 Barbadoss cross sheep and 16 jonggol sheep. The PCR-RFLP method was used to investigate the SLC25A30|SspI polymorphism. The association between the SLC25A30 gene and carcass characteristics was analyzed using the T-Test method. The results showed that the SLC25A30 (g.15912281 A>T) gene polymorphism was polymorphic in all breeds. The genotypes identified in the polymorphism were AA, AT and TT. The SLC25A30 gene was significantly associated (PT) gene indicates as a prospective gene for the purpose of identifying carcass characteristics in lamb meat.
