Abstract

This research was motivated by the lack of optimal use of leaves in forest plants, while there are many types of leaves in the forest. One use of leaves is to use them as raw material for making liquid smoke. This research was conducted to determine the yield of liquid smoke on forest plant species from their leaves. The research method used is the pyrolysis method with indirect combustion. This research was carried out by treating forest plant raw materials, namely kerai paying leaves (Filicium decipiens L.), bungur leaves (Lagerstroemia speciosa), mahogany leaves (Swietenia macrophylla King), teak leaves (Tectona grandis) and sungkai leaves (Peronema canecens Jack). The results of the research showed that the results of liquid smoke from the 5 types of plant leaves, namely sungkai leaves, had the highest grade 3 yield of 23.83% and the lowest grade 3 yield, namely mahogany leaves, of 17.81%. In grade 2 sungkai leaves the highest percentage was 21.12% and mahogany leaves had the lowest yield with a percentage of 16.18%. Meanwhile, in grade 1, sungkai leaves have the highest yield percentage of 19.33% and mahogany leaves have the lowest yield, namely 15.03%.

Abstract

This study examines the legal issues surrounding the arrest and detention of demonstrators, which have the potential to violate human rights in Indonesia. Using normative legal research methods with historical, case-based, and analytical approaches, this study analyzes the gap between progressive legal norms and repressive practices in the field. The results show that the arrest and detention of demonstrators often violate human rights due to several factors: first, the gap in implementation between the provisions of the Criminal Procedure Code (KUHAP) and international human rights standards and field practice; second, the weak understanding of human rights principles by officials and the lack of adequate training; and third, the practice of mass arrests without clear procedures, which contradicts the principle of individual criminal responsibility. This study identifies three legal mechanisms to provide protection: preventive measures through internal and external oversight; repressive measures through pretrial and criminal legal remedies; and restorative measures through mediation and institutional reform. The effectiveness of these mechanisms is hampered by institutional independence, procedural accessibility, institutional capacity, and public legal awareness. This study recommends comprehensive reform of the human rights protection system, strengthening oversight, and shifting the paradigm of handling demonstrations from a repressive approach to a human rights-based approach.
