Abstract

Inventarisasi barang menjadi penting dalam mendukung kegiatan operasional sekolah. Data alat dan barangyang dimiliki sekolah, terutama laboratorium perlu di inventarisasi untuk membantu sekolah dalammemanajemen alat dan barang sehingga mudah dalam perawatan maupun pelaporan data laboratorium. Saatini inventarisasi yang terjadi di SMA YPPK Yos Sudarso adalah berbentuk konvesional dalam bentuk buku,ini menyulitkan pihak sekolah dalam mendata alat dan barang karena harus ditulis secara manual danmembutuhkan waktu yang lama. Hal ini menyebabkan pihak sekolah sulit dalam menyajikan laporaninventaris dan berdampak pada data yang kurang akurat dan tidak mudah disajikan. Padahal di era masa saatini, telah banyak diciptakan sistem-sistem komputer yang bisa membantu kerja manusia dalammemanajemen alat dan barang. Penelitian ini menghasilkan sistem inventarisasi alat dan barang laboratoriumdalam bentuk sistem komputerisasi yang dapat membantu sekolah SMA YPPK Yos Sudarso mengatasipermasalahan yang ada. Penelitian dilaksanakan dengan beberapa tahap yaitu survey, studi pustaka dananalisis kebutuhan, perancangan sistem, monitoring evaluasi, dan implementasi sistem. Hasil penelitian iniberupa rancang bangun sistem informasi berbasis website yang dapat membantu menyajikan laporaninventaris Laboratorium IPA secara mudah dan akurat, dibuktikan dengan kepuasan pengguna dalam halini pihak guru melalui kuisioner mengatakan setuju bahwa sistem dapat membantu pihak Lab agarlebih mudah dan cepat dalam melakukan inventaris barang laboratorium.

Abstract

This research aims to determine the validity of comic-based teaching materials on hydrocarbon materials. This type of research is R&D research using the ADDIE model. The subjects of this research were students of class XI Science at SMA Negeri 1 Tanah Miring. The instrument used in data collection was a questionnaire. The results of the research showed that the development of a comic-based module on hydrocarbon compound material was declared valid and practical in terms of validity. The material validation results were 100% in the very valid category, the media validation was 92% in the very valid category, and the student questionnaire was 86% in the very valid category. valid.  Based on the research results, the comic-based teaching module as teaching material for hydrocarbon compounds was declared valid  for use as teaching material for hydrocarbon compounds.

Abstract

Purpose of the study: To find out the procedure for developing Merdeka Curriculum teaching modules on green chemistry material and producing products in the form of teaching modules on green chemistry material that are valid and practical. Methodology: This type of research is R&D using the 4D model, but in this study, it only reached the 3D stage, namely Define, Design, and Develop. The subjects of this study were 2 people validating the teaching module, 5 teachers responding, and 34 students of class X/Phase E of Senior High Scool 2 Merauke. The instruments used in data collection were interviews, questionnaires, and validation. Main Findings: The results of this study indicate that the Merdeka curriculum teaching module on green chemistry material from the product validation assessment is 95% with a very valid category. Reviewed from the practicality aspect, it can be seen from the teacher response assessment of 92% with a very practical category. Based on the results of the study, the Merdeka curriculum teaching module on green chemistry material is declared valid and practical to use. Novelty/Originality of this study: The teaching modules that are compiled are integrated with student abilities, facilities and infrastructure of Phase E at Senior High Scool 2 Merauke, assessments, materials are integrated with the local context. The teaching modules that are compiled are adjusted to the students' learning styles and have been validated by the validator.

Abstract

This study investigates the effectiveness of the POE learning model in enhancing cognitive learning outcomes of chemistry education students, with particular emphasis on redox reaction concepts in the Basic Chemistry 2 course. The research is motivated by the persistent challenge that chemistry is perceived as abstract and calculation-intensive, which hinders students’ conceptual understanding and reduces academic achievement. Employing a pre-experimental one-group pre-test – post-test design, data were collected from 12 second-semester students at Musamus University. Validated essay-based instruments were used to measure learning outcomes, and data analysis included N-Gain testing, Shapiro–Wilk normality testing, and paired sample t-tests. Results revealed a significant improvement in students’ performance, with mean scores rising from 19.4 (pre-test) to 74.6 (post-test), an N-Gain score of 0.67 categorized as moderate, and a t-count of 9.360 exceeding the t-table value of 2.22. The novelty of this research lies in the contextual application of the POE model under pandemic-induced learning constraints, demonstrating that active learning strategies integrating prediction, observation, and explanation are effective even within limited instructional settings. The contribution of this study is twofold: theoretically, it reinforces constructivist approaches in chemistry education by providing empirical evidence of POE’s impact on cognitive outcomes; practically, it offers lecturers a viable pedagogical alternative to foster motivation, engagement, and deeper understanding of abstract chemical concepts. These findings underscore the potential of POE as a scalable instructional strategy to address learning challenges in higher education science contexts.

Abstract

Eucalyptus oil leaves are one of the natural potentials of Wasur Village which is very useful and has selling value. So far, eucalyptus oil leaves are managed by the Wasur Village community to be made into eucalyptus oil and sold. The Wasur Village community only processes Eucalyptus Oil Leaves into Essential Oil, while Eucalyptus Oil Leaves can be processed into various useful products such as Bath Soap. This community pasrtnership service (PKM) activity was carried out in Wasur Village, Merauke, South Papua. This Activity aims to provide training to the Wasur Village community on how to process Eucalyptus Oil Leaves into Bath Soap as an innovative product that can be traded. This activity resulted in as increase in the production of the Wasur Village community through the addition of new innovative Bath Soap products that can be traded to increase community income.
