Abstract

This study aims to determine the stages in the process of making activated carbon, synthesis of porous polymer composites Cu(TAC) and activated carbon composites (KA-Cu(TAC) for adsorption of dissolved ammonia (NH4OH). To know the characterization results of activated carbon and KA- Cu(TAC), as well as knowing the optimum mass, concentration, and contact time of activated carbon KA-Cu(TAC) for the adsorption of dissolved ammonia. The research stages started from Empty Oil Palm Bunches (EFB) used as biosorbents for carbon production at 500oC. The resulting product was activated with H3PO4, then modified with porous polymer Cu(TAC) to make a composite. The KA-Cu(TAC) composite was synthesized by reflux method. Then MOFs, activated carbon and KACu(TAC) composite were characterized by BET. The BET characterization results showed that the successfully synthesized KA-Cu(TAC) composite experienced an increase in surface area.In the NH4OH adsorption process the optimum mass efficiency on activated carbon still increased at 8 grams while the KA-Cu(TAC) composite obtained an efficiency of 36, 6% and optimally at a mass of 4 g. At variations in concentration, the efficiency of the two samples still decreased. And the optimum time efficiency obtained in the NH4OH adsorption process with activated carbon was 70% and the KA-Cu(TAC) composite was 86.6%, both samples were equally optimal at 75 minutes.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh penerapan model Project Based Learning (PjBL) terintegrasi STEAM terhadap aktivitas belajar dan hasil belajar siswa pada materi laju reaksi, serta mengkaji hubungan antara kedua variabel tersebut. Penelitian menggunakan pendekatan kuantitatif dengan desain quasi experiment tipe nonequivalent control group design. Sampel penelitian terdiri dari dua kelas XI dengan jumlah total 72 siswa, yang dibagi menjadi kelas eksperimen dan kelas kontrol. Instrumen penelitian meliputi tes pilihan ganda untuk mengukur hasil belajar dan lembar observasi untuk menilai aktivitas belajar siswa. Hasil penelitian menunjukkan bahwa aktivitas belajar siswa pada kelas eksperimen lebih tinggi dibandingkan kelas kontrol, dengan perbedaan yang signifikan secara statistik. Selain itu, rata-rata hasil belajar posttest siswa pada kelas eksperimen juga lebih tinggi dibandingkan kelas kontrol, dengan nilai signifikansi < 0,05 dan nilai effect size sebesar 0,924 yang termasuk kategori besar. Hasil uji korelasi menunjukkan adanya hubungan positif yang kuat antara aktivitas belajar dan hasil belajar siswa. Dengan demikian, dapat disimpulkan bahwa penerapan model PjBL terintegrasi STEAM efektif dalam meningkatkan aktivitas dan hasil belajar siswa, serta berkontribusi terhadap pembelajaran yang lebih aktif, kontekstual, dan bermakna pada materi laju reaksi. The Influence of PjBL - STEAM on Student Activities and Learning Outcomes on the Reaction Rate Material This study aims to analyze the effect of the STEAM-integrated Project Based Learning (PjBL) model on students’ learning activities and learning outcomes in reaction rate material, as well as to examine the relationship between these two variables. The research employed a quantitative approach with a quasi-experimental design using a nonequivalent control group design. The sample consisted of 72 eleventh-grade students divided into an experimental class and a control class. The instruments used were a multiple-choice test to measure learning outcomes and an observation sheet to assess students’ learning activities. The results showed that students’ learning activities in the experimental class were higher than those in the control class, with a statistically significant difference. In addition, the average posttest score of students in the experimental class was higher than that of the control class, with a significance value of < 0.05 and an effect size of 0.924, which falls into the large category. The correlation analysis also revealed a strong positive relationship between learning activities and learning outcomes. Therefore, it can be concluded that the implementation of STEAM-integrated PjBL is effective in improving students’ learning activities and learning outcomes, as well as fostering more active, contextual, and meaningful learning in reaction rate material.

Abstract

The revitalization of the SMK curriculum projects serves that students are not only ready to work but also be able to create jobs through entrepreneurship. SMK Students are provided additional hours of entrepreneurship coursework in order to foster creativity, innovation, and an entrepreneurial mindset among students. Furthermore, students are also required to possess a social entrepreneurial mindset, which encompasses a business development perspective that takes into account social, economic, environmental, and health factors. In this program, students are given training in making soap from used cooking oil. Used cooking oil is a waste that has promising business prospects. Appropriate processing of used cooking oil can yield valuable products that satisfy the needs of the community. As a result of this training, up to 97% of students have acquired greater understanding regarding the hazards and advantages associated with used cooking oil. Students possess advanced skills in producing soap products using used cooking oil. Furthermore, students develop a greater awareness regarding health and the environment.
