Abstract

Tujuan dari penelitian ini adalah untuk mengetahui analisa sampel biodiesel B20 dan B100 yaitu berupa analisa angka asam, angka peroksida dan analisa warna dengan menggunakan colorimeter. B100 berbasis palm oil berasal dari PT Sumi Asih Oleochemical dan B20 berasal SPBU Pertamina. Analisa warna, angka asam dan angka peroksida dilakukan per 15 Hari sampai hari ke 60 untuk dilihat apakah ada perubahan yang terjadi. Biodiesel disimpan dengan diberi penambahan antioksidan dan tanpa penambahan antioksidan. Hal ini untuk mengamati efek penambahan antioksidan pada biodiesel selama penyimpanan. Antioksidan yang digunakan adalah Tersier Butil Hidroksi Quinolin (TBHQ) yang berfungsi untuk memperlambat atau mencegah proses oksidasi. Penyimpana biodiesel disimpan dengan dua kondisi yaitu tempat tertutup dan terbuka untuk diamati perubahan yang terjadi. Hasil penelitian ini menunjukkan bahwa penambahan antioksidan di ruangan terbuka berpengaruh terhadap perubahan warna yang signifikan hal ini disebabkan karena antioksidan bekerja pada temperatur tinggi selama penyimpanan. Kondisi penyimpanan pada temperatur diatas temperatur ambient dan terkena cahaya matahari lebih mempercepat terjadinya degradasi menyebabkan terjadinya penurunan kualitas biodiesel.

Abstract

The purpose of this article review is to evaluate the effectiveness of using Think Talk Write (TTW) learning modeling to improve elementary school students' mathematics learning outcomes. The TTW model involves a structured process of thinking, speaking, and writing to help students understand mathematical concepts better. The study method used is library research, where the data sources obtained are reviewed through books, scientific articles, scientific journals and other relevant written information. Data collection techniques are carried out through library research, focusing on literature related to the application of the TTW model in mathematics learning. The data obtained are analyzed using descriptive methods, which include tracing, reviewing and verifying in order to determine conclusions. The study data produced shows that the application of the TTW model can improve students' understanding and mathematical skills, and provide a clear picture of the effectiveness of this model in the context of mathematics education in elementary schools.

Abstract

The hastag No. viral No. justice has recently emerged on social media platforms creating its own discourse in the justice system. This research aims to examine how the impact of this phenomenon on the judicial system and to find the ideal mechanism of digital transformation of justice so that this phenomenon remains in line with the principle of due process of law.This research method uses a social legal with a case study approach and conceptual approach in answering the problem formulation. This research found that this phenomenon is motivated by the slow response of law enforcement officials and the lack of transparency of the judicial system, then the impact of this phenomenon disrupts the independence of the judiciary because it is tried by the media and has the potential to accommodate the spread of hoaxes and public disinformation. To answer these challenges, the author proposes a digital transformation of the judiciary through the optimization of SIPP, by adding a verification link feature on the SIPP page. So that access to case tracking becomes more transparent. In addition, there are also new rules regarding the publication of unresolved legal cases on social media by requiring the admin and related accounts to provide a disclaimer and link to the SIPP verification link of the case. This regulation is regulated through the revision of the ITE Law by the legislators.

This research uses normative juridical method with conceptual approach and statute approach. The results of the study found that there are several norm conflicts due to the inclusion of TAP MPR in the hierarchy, namely the issue of content material, the role of the consideration, the status of validity and constitutional testing which causes legal uncertaint. The author offers two alternative recommendation to the legislators. First, it is necessary to reassess to determine which provisions are still relevant to be maintained, so that a definite number is agreed upon. Then the content material is moved into the law. So that all MPR Decrees can still be used in the form of laws. Then revise the hierarchy of laws and regulations. Secondly, the lawmakers can just leave the MPR Decrees that are still recognised as MPR Decrees, with the legal status of laws and regulations. Whatever the lawmakers' choice, the MPR Decree must be removed from the hierarchy. Amandemen Undang Undang Dasar  tidak hanya mengubah wewenang dan kedudukan MPR dalam sistem ketatanegaraan namun juga berimbas pada produk hukum nya.
