Abstract

Biodiesel adalah salah satu bahan bakar alternatif yang dapat diperbaruhi, ramah terhadap lingkungan, tidak mempunyai efek terhadap kesehatan dan dapat dipakai sebagai bahan bakar kendaraan bermotor. Lipase dapat mengkatalisis reaksi transesterifikasi pada sintesis biodiesel dengan reagent yang sesuai dan kehadiran air yang terbatas. Lipase banyak digunakan dalam pengolahan lemak dan minyak, detergen, pengolahan makanan, sintesis bahan kimia, farmasi, sintesis kertas, produksi kosmetik dan juga industri biodiesel. Dalam penelitian ini, enzim lipase yang digunakan adalah enzim termostabil yang berasal dari mikroorganisme sumber air panas KHA-P12. Uji kualitatif dilakukan dengan menggunakan media CaCl2. Enzim lipase ekstraseluler yang diekspresikan oleh kultur KHA-P12 pada suhu 70oC selama 18 jam, diisolasi dan terhadap ekstrak kasar yang diperoleh dilakukan pengendapan dengan dua cara yaitu pengendapan aseton dan fraksinasi ammonium sulfat. Hasil endapan diliofilisasi untuk memperoleh bubuk lipase. Sedangkan uji aktivitas dilakukan dengan menggunakan substrat para-nitrofenol palmitat (pNPP). Sintesis biodiesel dilakukan dengan dikatalisis oleh enzim lipase. Sebagai kontrol dilakukan juga sintesis biodiesel dengan enzim yang telah dinonaktifkan terlebih dahulu. Reaksi transesterifikasi pada penelitian ini menggunakan minyak kelapa dan dengan menggunakan metanol. Hasil transesterifikasi dianalisis dengan menggunakan spektrometri massa. Uji kualitatif menunjukkan hasil positif adanya lipase yang disekresikan secara ekstraseluler oleh KHA-P12 dengan terbentuknya endapan kalsium monolaurat. Aktivitas spesifik lipase yang diendapkan dengan aseton adalah 1,52 unit/mg protein dengan jumlah endapan 2,7 gram dan fraksi 40-60% ammonium sulfat adalah 0,82 unit/mg protein dengan jumlah endapan 30 mg. Enzim lipase yang diendapkan dengan aseton memiliki aktivitas spesifik lebih tinggi dan endapan yang lebih banyak sehingga digunakan lebih lanjut pada reaksi transesterifikasi. Hasil spektrometri massa menunjukkan reaksi transesterifikasi tidak dapat berlangsung dengan enzim yang telah dinonaktifkan. Tetapi reaksi transestrifikasi dapat berlangsung dengan dikatalisis oleh enzim lipase

Abstract

Green chemistry is an alternative solution that can be used by chemistry teachers for safe and environmentally friendly chemistry experiments in schools. This community service aims to provide training to high school/vocational high school chemistry teachers in Ogan Ilir Regency, South Sumatra to carry out simple practical activities based on green chemistry. This service activity consists of 3 main stages, namely the preparation stage, the implementation stage and the evaluation stage. The target audience for this community service activity are 24 high school chemistry teachers from Ogan Ilir, South Sumatra. And furthermore, it is hoped that chemistry teachers who attend training can guide their chemistry teacher colleagues in their place. There are 7 simple green chemistry-based practical procedures collected from this service activity. The simple green chemistry-based practicum procedures are: 1) Redox reactions; 2) Making Binahong Covid-19 Herbal Soap; 3) Factors Affecting Reaction Rate; 4) Colloid-Tofu Making; 5) Colloids - Clumping (Coagulation) of Colloidal Particles; 6) Combustion of carbon compounds (complete and incomplete combustion); 7) Freezing Rubber Sap Using Pineapple Peel Extract. Overall, the target audience has been trained to make simple practical procedures based on green chemistry. This can be seen from the materials and practicum procedures that are in accordance with the basic principles of green chemistry, namely environmentally friendly, reducing environmental pollution, not classified as hazardous materials.

Abstract

This study aims to produce a valid and practical e-module of food chemistry constructivism based 5-phase Needham's. This research is development research with ADDIE development model combined with Tessmer formative evaluation. The stages of ADDIE development used in this study include the analysis stage, the design stage, and the development stage only, which then proceeds to the Tessmer formative evaluation stage which includes expert review, one to one, and small group. At the expert review stage, the e-module food chemistry was validated by experts from the fields of pedagogic experts, material experts and design experts. The results of the validation assessment scores obtained at the expert review stage in the pedagogic field are 0.848 (high), the material field is 0.895 (high), and the design field is 0.889 (high). This shows that the e-module constructivism based 5-phase Needham's that has been developed is valid. The practicality of the e-module constructivism based 5-phase Needham's is seen from the practicality questionnaire scores at the one-to-one stage and the small group stage. The one to one stage resulted in a score of 0.865 (high) and in the small group stage it was 0.865 (high), which means that the e-module based constructivism 5-phase Needham has been practically developed

Abstract

The background of the research is that skills are needed in accordance with the era of the industrial revolution 4.0, especially in the 21st century, namely critical thinking skills. For this reason, research is needed to determine the description of critical thinking skills. This research is a preliminary study that aims to describe the ability of critical thinking skills in learning science physics. Descriptive research method using google form. The research subjects were 33 students of SMP Negeri 59 Palembang. The results obtained are 25% of students are able to focus questions, 30% analyze questions, 32% consider reliable sources or not, 17% observe, consider observation reports, 39% do and consider deduction results, 38% do and consider induction results, 42% make and determine the value of judgment, 25% define, consider definitions, 21% identify assumptions, 44% determine actions, and 54% interact with others. The description of the critical thinking skills of junior high school students in the 4.0 industrial revolution era Physics science material is still in the low category, judging by the percentage of student responses. Suggestions for further research on efforts that can overcome the low critical thinking skills of junior high school students on Physics Science material.
