Abstract

The aging process is associated with the accumulation of oxidative stress that damages cellular function. D-galactose is used to induce aging-like conditions in animal models. Bajakah wood extract (Spatholobus littoralis Hassk.), which is traditionally used, is known to contain bioactive compounds with antioxidant activity. This study aimed to elucidate the effects of ethanol extract from Bajakah wood (Spatholobus littoralis Hassk.) on tyrosinase concentration and body weight in rats subjected to high-dose D-galactose induction. This laboratory experimental study used 36 male Sprague Dawley rats induced with D-galactose (500 mg/kgBW). The rats were divided into six groups: normal control, negative control, positive control (vitamin C 50 mg/kgBW), and three treatment groups that received Bajakah ethanol extract at doses of 25, 50, and 100 mg/kgBW. Body weight was monitored weekly for 8 weeks, and tyrosinase levels were analyzed at the end of the study. The negative control group showed fluctuations in body weight and the highest tyrosinase levels. Administration of Bajakah extract, particularly at a dose of 100 mg/kgBW, significantly reduced tyrosinase concentrations (p-value < 0,05) and resulted in a more stable weight gain profile compared to the negative control group. Bajakah wood ethanol extract showed an inhibitory effect on tyrosinase and improved weight stability in the D-galactose-induced rat model. These findings support the potential of this extract as a plant-based therapeutic agent for disorders related to oxidative stress and aging.

Abstract

Based on data from the Directorate General of Mineral and Coal, Ministry of Energy and Mineral Resources, in 2017, there are 9,353 Mining Business Licenses (MBL) with 9,074 MBLs entered in the DG of Mineral and Coal database. Of these, 6,565 MBLs passed the CnC requirements, while the remaining 2,509 MBLs were categorized as non-CnC. The focus of the problems studied are: (1) What is the Direction of Changes in Government Policy in the Mining Sector? (2) What is the relationship between Free, Prior and Informed Consent with the fulfillment of the constitutional rights of citizens in the mining sector? The method used in this study is doctrinal legal research focusing on sources of law. The result shows that (1) There are changes in government policy in the mining sector, which was only constrained in its implementation, but has now become more problematic because of the removal of the article on the imperative community participation; (2) In every policy setting, FPIC must be implemented and must be given to the community, especially those who are directly affected. Thus, FPIC can be said to be a form of community rights that must be fulfilled by the government as the licensor legally to fulfill the constitutional rights of its citizens.
