Abstract

Salah satu pewarna makanan yang banyak digunakan dalam proses pembuatan jajanan pasar tradisional adalah zat pewarna sintetis rhodamin B. Pewarna ini dilarang untuk digunakan pada makanan ataupun minuman karena bersifat karsinogenik atau dapat memicu pertumbuhan sel kanker. Tujuan dari penelitian untuk menganalisis kadar rhodamin B yang terdapat pada jajanan pasar. Sampel pada penelitian ini sebanyak 30 sampel jajanan pasar, populasi dalam penelitian ini yaitu 6 pasar yang terdapat di Kabupaten Lombok Timur. Metode yang digunakan dalam penelitia ini yakitu metode Kromatografi Lapis Tipis dan Spektrofotometri Uv-Vis, untuk mencari data kualitatif dan kuantitatif. Hasil penelitian yakni dari 30 sampel jajanan pasar yang telah di lakukan uji pewarnaan menunjukkan 6 sampel yang dicurigai mengandung rhodamin B, di uji KLT terdapat 5 sampel yang dinyatakan positif mengandung rhodamin B, dan di uji spektrofotometri menunjukkan semua sampel negatif mengandung rhodamin B. Namun terdapat pewarna lain yang di temukan pada uji spektofotometri Uv-Vis yaitu pewarna sintetis karmoisin. Dapat disimpulkan bahwa jajanan pasar yang beredar di pasar Kabupaten Lombok Timur negatif mengandung rhodamin B.

Abstract

This research aims to evaluate the effectiveness of online learning in achieving educational goals through understanding the material of international course subjects. A descriptive qualitative approach was employed, involving 87 students as research participants. Data collection techniques included questionnaires, interviews, and tests to measure students' understanding of international course materials. The results indicate that online learning effectiveness was rated as good based on an average questionnaire score of 55.25. Meanwhile, test results showed that 50.57% of students had a good understanding of the material, while 48.27% were below the proficient level. Thus, online learning is considered effective in enhancing understanding of international course materials. These findings highlight the importance of integrating technology in the learning process to achieve educational goals effectively.

Abstract

Peningkatan mutu manajemen sekolah di daerah seperti Lombok Timur membutuhkan sistem evaluasi yang komprehensif, terukur, dan digital. Namun, hingga kini belum terdapat instrumen yang dapat menilai kinerja manajemen sekolah secara strategis berbasis Balanced Scorecard (BSC) dengan melibatkan berbagai pemangku kepentingan. Penelitian ini bertujuan untuk mengembangkan e-instrumen evaluasi kinerja manajemen sekolah berbasis Balanced Scorecard menggunakan model ADDIE yang dapat mengukur empat perspektif utama BSC: keuangan, pelanggan, proses internal, dan pembelajaran serta pertumbuhan. Metode penelitian menggunakan pendekatan R&D model ADDIE melalui lima tahap: analysis, design, development, implementation, evaluation. Subjek penelitian meliputi kepala sekolah, guru, orang tua, dan siswa dari tujuh SMA Negeri di Kabupaten Lombok Timur. Validasi isi dilakukan oleh pakar menggunakan Content Validity Index (CVI), sedangkan validitas konstruk diuji dengan Confirmatory Factor Analysis (CFA) menggunakan SmartPLS. Nilai validasi ahli menunjukkan CVI 0,89 (kategori tinggi); hasil reliabilitas menunjukkan Cronbach’s Alpha > 0,7 di semua perspektif, dan uji System Usability Scale (SUS) menghasilkan skor 75,32 (kategori baik). Analisis n-gain per perspektif menunjukkan peningkatan sedang (keuangan 0,58; pelanggan 0,55; proses internal 0,54; pembelajaran 0,57). E-instrumen yang dikembangkan terbukti valid, reliabel, dan mudah digunakan, serta efektif dalam mendukung praktik evaluasi partisipatif berbasis data pada tingkat sekolah menengah. Produk ini dapat digunakan untuk memperkuat akuntabilitas dan transparansi manajemen berbasis Balanced Scorecard di lingkungan pendidikan daerah.

Abstract

This community service program aims to improve students’ and teachers’ knowledge and skills in producing Eco Enzymes as an environmentally friendly solution through project-based learning at MA Muallimat NWDI Pancor. The program applies a Participatory Rural Appraisal (PRA) approach involving 65 students and three biology teachers. Evaluation data are collected using questionnaires and analyzed descriptively. The results show that 96% of students understand the concept of Eco Enzymes, 94% comprehend their benefits, 93% demonstrate adequate skills in the Eco Enzyme production process, and 96% exhibit positive environmental attitudes, particularly in converting organic waste into Eco Enzymes. These findings imply that teachers and students are capable of processing locally available organic waste into beneficial Eco Enzyme products, thereby supporting environmentally sustainable practices.

Abstract

Car Free Day (CFD) events offer a practical venue for health promotion and early detection of noncommunicable diseases (NCDs). This community service program aimed to conduct blood pressure and random blood glucose screening while delivering brief NCD prevention education to the public at CFD Taman Rinjani, Selong. The activity was implemented on 30 November 2025 and involved 80 participants. The program included on-site measurements of blood pressure and random blood glucose, descriptive grouping of results by age and sex, and short counseling on NCD prevention and recommended follow-up. The findings indicated an age-related increase in mean systolic blood pressure, with the highest proportion of hypertension observed among older adults. Across younger and mid-adult groups, hypertension tended to be more frequent in men than in women. Elevated random blood glucose was uncommon overall but appeared mainly among women and was more noticeable in the older-age group. In summary, integrating screening and education in a public setting can help identify at-risk groups and encourage regular check-ups. Regularly scheduled CFD-based programs supported by selective referral pathways and strengthened lifestyle education may contribute to NCD risk reduction.

Abstract

Cancer education is an essential effort to improve public awareness and understanding, particularly among women, regarding the early detection of breast and cervical cancer. This community service activity aimed to provide education on cancer awareness, the importance of early detection, and the adoption of healthy lifestyles among Muslimat NWDI in East Lombok, West Nusa Tenggara. The activity was conducted through health education sessions combined with interactive discussions and an evaluation of participants’ understanding using a simple assessment instrument. The educational materials covered an introduction to breast and cervical cancer, breast self-examination (BSE), the importance of Pap smear screening, and lifestyle-related factors associated with cancer prevention. The results indicated that most participants demonstrated good to very good levels of understanding of the presented materials. Higher levels of understanding were observed among pre-elderly participants and those with a higher educational background. However, psychosocial barriers such as feelings of shame, fear, and cultural stigma related to reproductive health examinations were still identified. This socialization activity contributed positively to increasing participants’ awareness of the importance of early cancer detection. Nevertheless, continuous assistance and improved access to health services are needed to ensure the practical implementation of early detection behaviors within the community

Abstract

Digital education requires teachers to develop systematic textbooks while using technology responsibly. This paper reports a community service program on integrating artificial intelligence (AI) into textbook writing for teachers at SMAN 1 Selong and MA Mu’alimat NWDI Pancor, conducted from August to September 2025. The program consisted of four stages: socialization, technical workshop, mentoring, and presentation–evaluation. Participants practiced using ChatGPT, Grammarly, Turnitin, Canva, and reference-management tools to support drafting and editing. The results show that 40 textbook drafts (at least three chapters each) were produced and can be further refined for classroom use. In addition, 70% of participants were able to independently operate at least three AI-based tools. These findings suggest that hands-on training combined with mentoring can strengthen teachers’ technical capacity and accelerate the textbook-writing process, supporting more relevant and innovative teaching materials in schools
