Abstract

The mas snail (Pomacea canaliculata) is one of the pests of paddy’s plant that needs to be controlled because it can attack the nursery and paddy that is ready to be harvested. Jamblang leaves are known to have biactive secondary metabolites such as alkaloids, flavanoids, saponins, terpenoids and tannins. The purpose of this study was to test the methanol extract of jamblang leaves on the mas snail. This research was conducted by extracting 1000ml of jamblang leaf powder with 1000ml of methanol for 3 days, then the extraction results were thickened and made into several doses of 0 ml/L (P0), 1 ml/L (P1), 2 ml/L (P2), 3 ml/L (P3). ). 4ml/L (P4) and 5ml/L (P5). Each dose was tested on 10 golden snails that had been given well water and gamal leaves as feed. The results showed that the 5ml/L (P5) treatment caused 100% mortality at 48JSA and the lowest attack intensity on gamal feed was 8.33%.

Abstract

This article examines the changes in the position, functions, and role of the People’s Consultative Assembly (Majelis Permusyawaratan Rakyat/MPR) following the amendments to the 1945 Constitution of the Republic of Indonesia. This study employs a literature review method by analyzing constitutional law textbooks, academic journals, official MPR documents, and historical records of the reform era. Prior to the amendments, the MPR functioned as the highest state institution with extensive authority, including electing the President and Vice President and formulating the Broad Outlines of State Policy (GBHN) as national development guidelines. After the constitutional amendments, the MPR was transformed into a high state institution with a position equal to other state institutions, and its authority became more limited and focused, particularly on amending and enacting the Constitution, inaugurating the President and Vice President, and deciding on presidential dismissal under specific conditions based on decisions of the Constitutional Court. These changes represent not merely a reduction of authority but an effort to establish a more democratic and accountable constitutional system through the strengthening of the checks and balances principle. The findings indicate that despite its reduced authority, the MPR continues to play a crucial role in safeguarding constitutional continuity and symbolizing popular deliberation within Indonesia’s constitutional framework.
