Abstract

Kegiatan pengabdian kepada masyarakat merupakan bagian integral dari Tri Dharma Perguruan Tinggi, yang melibatkan lembaga, dosen, dan mahasiswa dalam berkontribusi kepada masyarakat. Dalam konteks ini, dilakukan pengabdian melalui edukasi pengolahan sampah organik dan anorganik bagi masyarakat pesisir pantai di kelurahan Leato Selatan untuk mendukung program Kampung Bahari Nusantara (KBN) yang bertujuan meningkatkan kesejahteraan masyarakat pesisir pantai. Tujuan dari kegiatan pengabdian ini adalah memberikan pengetahuan, pemahaman, kepedulian, dan keterampilan dalam mengolah sampah, baik organik maupun anorganik. Proses pelaksanaan kegiatan mencakup observasi lokasi pengabdian, perencanaan, pelaksanaan, dan evaluasi kegiatan. Hasil yang diperoleh dari kegiatan ini antara lain adalah: (1) penghasilan produk olahan sampah berupa pupuk organik dan bunga dari plastik, (2) peningkatan pengetahuan dan kepedulian masyarakat terhadap kebersihan lingkungan, dan (3) terbentuknya kelompok ibu-ibu pengolah sampah, terutama dalam pembuatan pupuk dan bunga dari plastik. Terjadi peningkatan persentase pengetahuan di kalangan sasaran, yaitu anak-anak sebesar 82%, remaja sebesar 82%, dan dewasa sebesar 86%. Dengan demikian, dapat disimpulkan bahwa kegiatan pengabdian ini berhasil meningkatkan pengetahuan, sikap, dan keterampilan peserta pelatihan dalam Pengolahan sampah organik dan anorganik.

Abstract

Community service activities constitute one of the core mandates (Tri Dharma) of higher education and may be regarded as a key responsibility of institutions, lecturers, and students. A home yard is an open space surrounding a residence. When properly maintained, it can create an attractive, comfortable, healthy, and pleasant environment that enhances residents’ well-being at home. This community service program aimed to optimize the utilization of home yards through a vertical cultivation (verticulture) system using plastic waste, in order to generate additional household income and improve aesthetic value. In addition, the program promoted the reuse and recycling of plastic waste as planting media. The methods employed included field observation, communication of the activity plan, collection of plastic waste, program socialization, counseling, training and group sharing sessions, and finally monitoring. The socialization results demonstrated that used cooking oil packaging could be repurposed into planting containers and beverage bottles could be utilized as verticulture planting media. The main crop emphasized in this program was chili, which is commonly needed in every household. Other crops suitable for verticulture include annual, high-moisture herbaceous plants such as spinach, water spinach (kangkung), and lettuce, as well as tomatoes and other plant species. The implementation of this program motivated community groups to manage household waste into compost and enhanced their knowledge and skills in vegetable and medicinal plant cultivation techniques. As a result, the surrounding environment became cleaner and greener, and community members were able to meet their needs for vegetables and medicinal plants around their homes.

Abstract

This study aims to analyze the ability of XII grade high school students in solving C4 level chemistry problems based on three indicators (Differentiating, Organizing, and Attributing) using Rasch modeling. This research is a quantitative study with a non-experimental research design (survey). The results showed that the level of analyzing students with an overall percentage reached 44.3%. Analysis based on indicators, Differentiating ability reached 47.06% (sufficient category), Organizing was at 44.88% (sufficient category), and Attributing also reached 40.56% (sufficient category). The ability to analyze students in SMAN A had an average value of 0.94, SMAN B had an average value of 0.11, SMAN C had an average value of -0.09, SMAN D had an average value of -0.62 SMAN E had an average value of -0.96, SMAN F had an average value of -0.25, SMAN G had an average value of 0.18, SMAN H had an average value of -0.62, while SMAN I had an average value of -0.73.

Abstract

Developing students’ critical thinking skills remains a major challenge in chemistry education, particularly in thermochemistry, which requires conceptual, symbolic, and quantitative reasoning. While STEM-integrated problem-based learning (PBL–STEM) has gained increasing attention, limited studies have examined how this instructional approach aligns with the cognitive structure of critical thinking. This study investigated the effect of the PBL–STEM model on students’ critical thinking skills in thermochemistry. A quasi-experimental design involving 64 tenth-grade students was employed. Participants were selected using purposive sampling and assigned to an experimental group and a control group. Critical thinking skills were measured using a 20-item essay test based on Facione’s framework. The instrument demonstrated high reliability (Cronbach’s α = 0.915) and strong content validity (CVI = 0.93). Data were analyzed using an independent-samples t-test. Results showed a significant difference between groups (t = 4.997, p < 0.05), with the experimental group achieving higher mean scores (M = 80.80) than the control group (M = 65.38). The effect size (Cohen’s d = 1.25) indicates a large instructional impact. These findings suggest that STEM-integrated PBL provides a cognitively aligned framework for fostering critical thinking in chemistry learning.
