Abstract

Sumbawa society is rich in culture, especially in traditional medicine. People use materials from the surrounding environment, including plants and animals, as active ingredients for medicine. Newborn babies and toddlers are susceptible to blockage of the respiratory tract with mucus. In babies, it is usually caused by an imperfect suction process, while in toddlers, it is caused by bacteria or viruses. The Samawa people use a mixture of cuttlefish (Sepia sp.) and eucalyptus oil as a medicine that effectively removes mucus from the body. The active ingredient in cuttlefish has an unpleasant odour and cannot be stored for long. When they need cuttlefish, people must look for them in markets or traders on the coast. Of course, this takes time to use. The ointment production innovation has many advantages, including practicality, no fishy smell, ease of obtaining, and ease of storage for the long term. Using the natural active ingredient lemongrass, essential oil adds aromatherapy and provides warmth to the chests of babies and toddlers. Natural active and gel-based ingredients are safe to use without side effects. The ointment was tested for active ingredient content using GCMS and organoleptic tests for gel stability, spreadability (homogeneity), pH, and skin irritation. Based on the description above, it can be concluded that the ointment product is made from an anti-skin irritation gel base, pH 7, and gel spreadability of 5.5 cm. The active substance comes from cuttlefish Sepia sp. by inhibiting the COX-2 enzyme and reducing the production of prostaglandin E2 (PGE2), an essential inflammatory mediator in the pathogenesis of asthma and bronchitis. The simple production process means that the price of the ointment is within people's purchasing power.

Abstract

This study aims to determine the feasibility and practicality of interactive learning media based on augmented reality for carbon compounds. This research is a type of development research that adopts the 4D model (define, design, develop, disseminate) but is limited only to the development stage (develop). The population in this study consisted of 124 students from SMAN 1 Labuhan Haji. The sampling technique used in this study was random sampling. The assessment aspects evaluated by three validators have three aspects measured through expert validation sheets. The level of practicality of the media was measured through a practicality questionnaire sheet completed by 24 students of Class XI MIPA at SMAN 1 Labuhan Haji. The results showed that the level of media feasibility, as assessed by the validator, was 0.68, indicating that the developed media had a high level of validity. The results of the media practicality test showed that students gave positive responses to all media components, with a practicality percentage of 87.5%. Based on these results, it can be concluded that the media developed is feasible and practical to use.

Abstract

This research aims to develop guided inquiry-based LKPD and critical thinking instruments in acid-base chemistry lessons that are valid and practical. The research uses the R&D (Research and Development) method, a 4D development model which is carried out in only three stages (3D), namely Define, Design, and Develop. The results of the validity test using the Aiken's V index obtained a V value for the LKPD of 0.81 and for the instrument of 0.82, which shows that the LKPD based on guided inquiry and critical thinking instruments on acid-base material are very valid to use. The results of the practicality assessment of the LKPD and instruments showed that the average percentage of the LKPD was 88% and the instrument was 81%, which means that the LKPD based on guided inquiry and critical thinking instruments on acid-base material were very practical to use.Based on these data, it can be concluded that the guided inquiry-based LKPD and critical thinking instruments developed can be used in chemistry learning on acid-base material.

Abstract

This study aims to reveal the effect of the CINQASE learning model on critical thinking skills and students' conceptual understanding of acid-base titration material at SMAN 6 Mataram. This study is a quantitative study with a quasi-experimental method. The population in this study were students of Phase F Class XI SMAN 6 Mataram. The research sample was taken using the cluster random sampling technique and obtained students of class XI 4 as the control class and students of class XI 3 as the experimental class. The research instrument in measuring critical thinking skills and conceptual understanding was in the form of 5 test questions that had been tested for validity and reliability. The results of the N-Gain values ​​obtained from the experimental class and the control class were analyzed by testing the normality of the N-Gain and homogeneity of the N-Gain first and then testing the hypothesis. Hypothesis testing was carried out using the t-test. The results showed that there was an effect of the CINQASE learning model on students' critical thinking skills and conceptual understanding of acid-base titration material with a significance value of t count > t table. Student responses to the CINQASE model also showed positive results. In conclusion, the CINQASE learning model is effectively applied in chemistry learning to improve critical thinking skills and conceptual understanding.

Abstract

This study aims to develop a chemical problem-based learning module on petroleum material at SMAN 2 Mataram by using validity and practicality tests. The research model used is the 4D model, namely define, design, development, and dissemination. This study used a purposive sampling technique in sampling, involving 36 students of class XI MIPA 8 at SMAN 2 Mataram who were then used as respondents in a practicality test. Data analysis shows a good level of validity, with an Aiken V index of 0.88. Meanwhile, the practicality module was analyzed using the practicality index (student and teacher response questionnaire) so that the practicality module proportions were 86% (students) and 94% (teachers). These results provide evidence that the problem-based learning chemistry module on petroleum material is valid and practical. Therefore, this module can be applied in the learning process at SMAN 2 Mataram and maybe also in other schools that have a similar curriculum

Abstract

Banyak laporan penelitian mengungkapkan bahwa mikrolastik sudah menjadi ancaman bagi kehidupan karena dapat memberikan dampak ekotoksikologi bagi biota laut yang kemudian bisa berdampak buruk kepada manusia. Bahaya ini berasal dari zat aditif (yang bersifat toksik) yang mengalami leaching-out di dalam sistem pencernaan mahluk hidup yang tanpa sadar mengkonsumsi mikroplastik. Salah satu bahaya yang nyata adalah mikroplastik dapat mengurangi kesuburan pria dan bisa menyebabkan demaskulinisasi. Kegiatan pengabdian kepada masyarakat (PkM) yang dilakukan di SMAN 2 Mataram pada Augustus 2024 telah selesai dilaksanakan dengan baik. Tujuan dari kegiatan ini adalah untuk memberi pemahaman kepada guru-guru di SMAN 2 Mataram akan bahaya mikroplastik terhadap biota laut dan manusia. Pemilihan target sasaran berdasarkan posisi guru yang sangat strategis sebagai agen perubahan. Bentuk kegiatan adalah berupa Sosialisasi Bahaya Mikroplastik terhadap Kesehatan Masyarakat untuk Keberlanjutan Lingkungan Laut yang Sehat yang dirancang dalam beberapa langkah pemaparan yang dimulai dari pretest-posttes, pemberian materi secara ekspositori diikuti dengan diskusi dan kuesioner untuk memeperoleh feed-back dari peserta. Pemaparan difokuskan pada ancaman bahaya mikroplastik terhadap biota laut dan kesehatan manusia. Selanjutnya diskusi dan tanya jawab yang konstruktif. Selama interaksi di ruang kelas, peserta terus riuh aktif mengikuti dan bertanya jawab dengan sesama mereka dan terutama dengan pemateri. Hasil dari kegiatan ini antara lain terjadi peningkatan pemahaman akan ancaman bahaya mikroplastik terhadap biota laut dan manusia dan pemahaman akan cara mereduksi ancaman tersebut. Rerata skor pretest ialah 25 – 45 dan rerata skor posttest ialah 55 -75 dari 32 responden. Diperoleh feedback yang positif dari peserta terhadap kegiatan yang disajikan. Selanjutnya, peserta juga mengungkapkan bahwa materi yang dipaparkan dapat memperkaya pembelajaran di kelas. Guru, sebagai agen perubahan juga berkomitmen menyebar luaskan pemahaman ini kepada murid dan masyarakat di sekitarnya dan komitmen paling menggembirakan adalah peserta akan berusaha ikut aktif mengurangi pelepasan limbah mikroplastik ke lingkungan.
