Abstract

UV-Visible spectrophotometry (UV-Vis) is one of the most widely used instrumental analytical methods in the fields of pharmacy, food science, and analytical chemistry, particularly for determining the concentration of active compounds in various types of samples. The working principle of UV-Vis spectrophotometry is based on the ability of a compound to absorb light at a specific wavelength, resulting in an absorbance value proportional to the concentration of the substance in solution. This method is considered efficient due to its relatively simple operation, short analysis time, and lower cost compared to other instrumental methods such as HPLC, AAS, or GC-MS. In addition, UV-Vis spectrophotometry can be applied to a wide range of compounds containing chromophoric groups, making it suitable for analyzing herbal products that consist of complex natural matrices. This study aims to review the application of UV-Vis spectrophotometry in the analysis of active compounds in herbal products through a literature review of ten relevant and recent scientific journals. Based on the results of the review, it was found that UV-Vis spectrophotometry is widely used to analyze compounds such as flavonoids, vitamin C, caffeine, paracetamol, and oxalates derived from natural sources such as tea, fruits, vegetables, as well as traditional herbal preparations such as jamu and supplements. In addition, this method is also applied in solubility studies of active compounds within drug delivery systems such as Self-Nanoemulsifying Drug Delivery Systems (SNEDDS), analytical method validation, and evaluation of compound stability in final formulations. Several studies also demonstrated the ability of UV-Vis spectrophotometry to detect the presence of synthetic contaminants in herbal products quickly and simply. From the overall findings, it can be concluded that UV-Vis spectrophotometry plays a significant role in the development, formulation, and quality testing of herbal-based products. This method is not only practical and efficient but also capable of producing reliable quantitative data that can be applied in various research and industrial contexts.

Abstract

Kegiatan pengabdian masyarakat ini dilaksanakan sebagai upaya menjawab rendahnya minat belajar dan semangat dalam menempuh jenjang pendidikan anak-anak di pekon giri tunggal, dengan memanfaatkan film Laskar Pelangi sebagai media motivasi dan pembelajaran. Tujuan utama kegiatan ini adalah menghidupkan kembali semangat belajar generasi muda sekaligus menanamkan nilai positif melalui pesan moral yang terkandung dalam film. Metode yang digunakan berupa pendekatan partisipatif yang melibatkan pemutaran film secara bersama, diskusi interaktif, serta mengungkapkan gagasan dari cita-cita besar dari anak-anak pekon giri tunggal. Tahapan kegiatan dirancang agar anak-anak tidak hanya menjadi penonton pasif, tetapi juga mampu merefleksikan nilai perjuangan, kerja keras, dan pentingnya pendidikan sebagaimana ditampilkan dalam film. Hasil pelaksanaan menunjukkan adanya antusiasme siswa dalam mengikuti proses belajar, serta keberanian mengekspresikan impian diri, dan meningkatnya kesadaran tentang arti penting pendidikan bagi masa depan. Dengan demikian, optimalisasi film Laskar Pelangi terbukti efektif sebagai media pengabdian masyarakat yang mampu menumbuhkan kembali semangat belajar dan samangat bersekolah ke jenjang yang lebih tinggi di wilayah pedesaan.

Abstract

Kekerasan seksual terhadap anak merupakan permasalahan krusial di lingkungan pendidikan yang menimbulkan dampak traumatis berkelanjutan pada aspek psikologis, emosional, dan perkembangan kepribadian siswa. Anak usia sekolah dasar sangat rentan karena keterbatasan pengetahuan tentang perlindungan diri dan pemahaman batasan pribadi yang masih minim. Penelitian ini bertujuan untuk mengkaji efektivitas penyuluhan kekerasan seksual dalam membangun ketahanan psikologis anak sekolah dasar di SD Negeri 1 Giri Tunggal serta mengevaluasi dampaknya terhadap pembentukan karakter positif siswa. Kegiatan dilaksanakan melalui pendekatan psikoedukatif dan interaktif menggunakan teknik diskusi kelompok dan simulasi peran (role play) yang melibatkan 27 siswa dengan didampingi 8 mahasiswa dari lintas program studi. Berdasarkan pelaksanaan program, terdapat tiga hasil utama: (1) peningkatan pengetahuan siswa mengenai bentuk-bentuk kekerasan seksual dan hak tubuh, (2) pengembangan empati dan moralitas melalui refleksi pengalaman, serta (3) penguatan keberanian untuk menyuarakan ketidaknyamanan dan mencari bantuan. Temuan menunjukkan bahwa program penyuluhan berkelanjutan efektif memperkuat ketahanan psikologis anak dan mendukung terciptanya lingkungan sekolah yang aman, sehingga penting diintegrasikan dalam kurikulum pendidikan dasar guna melindungi dan membangun generasi muda yang memiliki kesadaran tinggi akan hak dan keselamatan diri.

Abstract

Stunting, kondisi gagal tumbuh pada balita akibat kekurangan gizi kronis, menjadi masalah serius global dengan 148,1 juta anak di bawah usia 5 tahun terpengaruh pada 2022 (WHO, 2022). Di Kabupaten Jember, prevalensi stunting mencapai 34,9% pada 2022 (Kemenko PMK, 2023). Penelitian ini bertujuan untuk meningkatkan pengetahuan ibu hamil dan menyusui mengenai pencegahan stunting melalui penyuluhan dan pelatihan menyusun menu MP-ASI di Desa Umbulsari. Kegiatan ini dilakukan dalam waktu tiga jam, meliputi observasi, pelatihan, dan evaluasi. Hasilnya menunjukkan peningkatan pengetahuan ibu tentang stunting dan gizi seimbang, serta kemampuan dalam menyusun menu MP-ASI. Kegiatan ini diharapkan dapat berkontribusi pada pengurangan stunting di daerah tersebut dengan melibatkan tenaga kesehatan secara berkelanjutan.

Abstract

This research is motivated by the low social communication skills of fifth grade students of SDN 005 Langgini. Therefore, the researcher determines an alternative solution to the problem in the form of implementing learning using the discovery learning model to improve the social communication skills of fifth grade students of SDN 005 Langgini. The type of research applied is (PTK) Classroom Action which is carried out in two cycles of stages in the form of planning stages, implementation stages, observation stages, and reflection stages. The data collection techniques used are observation and documentation techniques. The collected data will then be processed using qualitative and quantitative processing techniques. The results of the study obtained were an increase in students' social communication skills with the implementation of the Discovery Learning learning model for grade V students of SDN 005 Langgini in the subject of Science, the material of Indonesia is rich in culture, increasing especially in the second cycle, as seen from the results of the observation sheets that have been carried out by researchers in each cycle. During cycle I meeting 1, the success rate was only 29.5% and the second meeting was 39.6% which reflects a success rate of only 34.3% and this is included in the less category. While in cycle II meeting 1 the success rate was 53.8% and the second meeting was 81% which reflects a success rate of 76.8% this is included in the good category
