Abstract

Free Fatty Acids (FFA), which include unsaturated fatty acids like oleic and linoleic acid and saturated fatty acids like palmitic and stearic, are present in most oil compositions. The various negative impacts of FFA require these compounds to be eliminated.  This research aims to separate FFA using Liquid-Liquid Extraction (LLE) and determine the levels of FFA using acid-alkalimetric titration in corn oil and palm oil. FFA extraction was carried out for 4 minutes with a solvent ratio of 9,5 ml diethyl ether + 40 ml ethanol + 0,5 ml water. By adding 1M Na2SO4, re-extraction was carried out for 3 minutes. The results obtained were 0.95% FFA levels in corn oil and 1.26% FFA levels in palm oil. FFA levels of both oils are still below the SNI FFA percentage of 3%; besides that, it is found that the FFA levels in palm oil are higher than in corn oil

Abstract

Chemistry is a science that studies the composition, structure, and properties or changes of matter. In chemistry, there are three levels of representation namely macroscopic, submicroscopic, and symbolic. Chemistry is a branch of science that requires students to have an understanding of concepts and mathematical skills, one of which is colligative properties. The aim of this research is to analyze the concept of colligative properties so that students don’t have misconceptions and can enhance their understanding through a multi-representation approach. The method used is the scientific approach, based on a series of five main learning experiences: Observing, Questioning, Reasoning, Associating and Communicating. Information collection techniques include concept maps, concept analysis, and propositions. Colligative properties consist of vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. The van't Hoff factor is present in most colligative properties where the solute is an electrolyte substance.

Abstract

Students often consider chemistry as a difficult subject to understand because that most teachers still use conventional teaching methods and lack of application of innovative learning media. Along with the times, a student-centered learning approach is one of the potential innovations that can be applied in learning chemistry, such as project- and game-based learning. This community service aims to enhance teachers' understanding and skills in implementing project-based learning and games in chemistry learning. The methods of this service are lectures and training. The subjects were 89 chemistry teachers from 40 high schools who are members of the Chemistry MGMP in Sidoarjo. The activities were carried out in the form of: (1) Socialization and sharing sessions on PjBL; (2) Socialization and sharing sessions on GBL; (3) Integration of project- and game-based learning in chemistry learning; (4) Demonstration of project- and game-based learning in chemistry learning; and (5) Sharing session on project-based teaching modules and games in chemistry learning. After participating in the activity, teachers' understanding increased by 35.37%. This activity produces outputs in the form of best practices and teaching modules.

Abstract

Dakwah adalah salah satu upaya yang bisa dilakukan untuk menyebarkan makna moderasi beragama dengan pelaku utama seorang santri yang merupakan penerus ulama. Namun, banyak santri yang belum mampu mengaktualisasikan ajaran pesantren yang bersumber dari turats atau kitab ulama nusantara menjadi konten dakwah di media digital yang sesuai dengan perkembangan zaman. Tujuan kegiatan ini adalah untuk mencetak konten kreator dari kalangan santri untuk menggencarkan dakwah digital berbasis moderasi beragama. Kegiatan ini menggunakan metode kuantitatif dengan pendekatan studi kasus. Pengabdian yang diimplementasikan dalam bentuk pelatihan ini dilaksanakan selama dua hari, pada 20-21 Mei 2023 di Ma’had Madrasah Aliyah Negeri (MAN) Kota Batu dengan jumlah peserta 50 orang dari perwakilan pondok pesantren dan Ma`had di Kota Batu. Pelaksanaan pelatihan ini mendapat predikat berhasil dengan persentase 66% peserta menjawab pelaksanaan pelatihan berjalan sangat baik, 88% peserta menjawab akan mengikuti pelatihan lanjutan jika ada program lagi, dan 60% peserta menjawab pelatihan konten kreator ini sangat efektif untuk digelar. Tim kegiatan pengabdian berharap agar pelatihan seperti ini bisa terus dilakukan untuk memberikan edukasi dakwah digital dan menyebarkan nilai moderasi kepada seluruh santri yang ada di nusantara.
