Abstract

Problem solving is a vital ability for students to be able to solve physics questions. Physics learning in the classroom needs to improve and develop this ability in students. Therefore, this research aims to analyze the students' problem-solving abilities as learning outcomes that have been obtained by high school students in Palangkaraya City. The research type is descriptive research with survey methods. The instrument used was a problem-solving ability test for the topic of work and energy. It was implemented on 155 12th grade in Palangkaraya. The results were analyzed quantitatively to identify the ability to describe problems, identify variables, plan solutions, implement plans, and check and evaluate the process. The results show that the students’ ability to describe problems and identify variables is better than other abilities. They can identify the variables in the questions and describe the physical situations. In addition, when the questions involve formula analysis and calculations, many students are unable to identify the equations that must be applied. They also have problems with their mathematical abilities to obtain the final answer. Educators need to concern these results in designing work and energy learning that can accommodate students' problem-solving abilities.

Abstract

Physics is one of the subjects that plays a role in developing analytical, critical, inductive, and deductive skills in problem-solving through a scientific approach. However, various studies reveal that this subject is less popular because many students perceive it as abstract, difficult to understand, and less relevant to everyday life, resulting in a low understanding of physics concepts. This study aims to explore students' perceptions of the implementation of research-based learning in the heat transfer material. The research subjects were 20 students enrolled in the Thermodynamics course of the Physics Education Study Program at FKIP, University of Palangka Raya. The instrument used was a perception questionnaire. The results showed that students had a positive perception of their learning experience using a research-based approach. Based on these findings, research-based learning can be considered an alternative strategy for more meaningful learning, especially in physics education.

Abstract

Abstract: This study is motivated by the importance of developing learning patterns that emphasize the formation and understanding of students through active learning. One form of learning that can support this goal is research-based learning. Research-based learning promotes student-centeredness and integrates research into a meaningful learning process. In this work, the students are actively involved in real research related to fluid convective flow topics. This research aims to describe the impact of research-based learning on students' understanding of convective fluid flow topics. A pre-experimental research method with a one-group pre-test and post-test design was used. Participants were taken from students in the Physics Education Study Program at the University of Palangka Raya taking thermodynamics courses. The number of participants was 20 students. The test instrument is in the form of essay questions consisting of five questions related to fluid convective flow material. The finding indicates that prospective teacher students' understanding was significantly increased with a high category (N-Gain score of 0.74). Based on this study, research-based learning activities could be considered an alternative to conducting meaningful learning activities, especially in fluid convective flow topics.         Keywords: fluid flow, physics learning, research-based learning.DOI: http://dx.doi.org/10.23960/jpmipa/v25i1.pp53-65

Abstract

Abstrak: Keadaan tanah desa Anjir kabupaten Pulang Pisau didominasi lahan gambut yang memiliki kendala tinggi untuk budidaya hortikultura, seperti tingkat kemasaman (pH) rendah dan kandungan unsur hara yang minim. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk meningkatkan kapasitas petani dan produktivitas semangka melalui penerapan teknologi ramah lingkungan kepada 25 anggota kelompok Tani “Pelangi Nusantara (MAHIKAT)” di Desa Gohong, Kecamatan Kahayan Hilir, Kabupaten Pulang Pisau. Selain itu, metode pelaksanaan PkM meliputi pelatihan teknis, pendampingan, dan implementasi demplot percontohan seluas 0,8 ha yang menerapkan teknologi spesifik gambut (pengapuran, amelioran kompos, irigasi terkontrol). Evaluasi selama kegiatan PkM dilakukan untuk memantau keaktifan peserta dan progres demplot melalui observasi langsung, wawancara dan diskusi dengan mitra serta dokumentasi kegiatan. Sedangkan evaluasi pada akhir kegiatan dilakukan untuk menilai hasil dan dampak program melalui analisis produksi, survei kepuasan dan persepsi mitra serta evaluasi keberlanjutan usaha. Hasil kegiatan menunjukkan peningkatan pemahaman petani sebesar 42%, terjadi peningkatan produktivitas semangka 40-55% (dari 18-20 menjadi 28 ton/ha), dan peningkatan pendapatan bersih petani sebesar 65%. Simpulan dari kegiatan ini adalah model teknologi budidaya ramah lingkungan terbukti efektif meningkatkan produktivitas dan ekonomi petani di lahan gambut dan dilakukan program pendampingan berkelanjutan.Abstract: The soil conditions in Anjir Village, Pulang Pisau Regency, are dominated by peatlands that pose significant challenges for horticultural cultivation, such as low acidity levels (pH) and minimal nutrient content. This Community Service (PkM) activity aims to enhance farmer capacity and watermelon productivity through the application of environmentally friendly technologies to 24 members of the "Pelangi Nusantara (MAHIKAT)" Farmer Group in Gohong Village, Kahayan Hilir District, Pulang Pisau Regency. The implementation methods include technical training, mentoring, and the establishment of a 0.8-hectare demonstration plot applying peatland-specific technologies (liming, compost ameliorant, controlled irrigation). Evaluation during the activity was conducted to monitor participant engagement and demonstration plot progress through direct observation, interviews and discussions with partners, and activity documentation. Meanwhile, evaluation at the end of the activity was performed to assess the results and program impact through production analysis, satisfaction and perception surveys with partners, and business sustainability evaluation. The results show a 42% increase in farmer understanding, a 40-55% increase in watermelon productivity (from 18-20 to 28 tons/ha), and a 65% increase in farmer net income. The conclusion of this activity is that the environmentally friendly cultivation technology model has proven effective in improving productivity and farmer economics in peatlands, and a sustainable mentoring program was implemented.
