Abstract

Energy sources from non-renewable materials such as petroleum are limited and will continue to decrease. Meanwhile, efforts to find renewable energy sources as reserves require quite expensive costs with a relatively long duration. Therefore, it is necessary to research renewable energy sources, such as corn stovers and coconut shells. This study is generally carried out by making charcoal or carbonization, briquetting, and testing the quality of briquettes. The variables used in this study are the composition of corn cob charcoal and coconut shells. The composition of the mixture used consists of 5 comparative variables, namely sample A = 1: 1, sample B = 1: 2, sample C = 1: 3, sample D = 2: 1, and sample E = 3: 1 with a drying temperature of 100 oC. This study aims to produce biobriquettes from variations in the ratio of good and quality corn cob and coconut shell so that they can be used as environmentally friendly alternative fuels. This study concludes that the optimal mixture variation to produce good quality biobriquettes is found in sample C with a water content of 2.20%, ash content of 3.22%, sulfur content of 0.07%, and a calorific value of 7339 cal/gram because it has a lower optimization compared to other samples and meets the specified standards.

Abstract

Scientific creativity is an important skill in 21st century learning. In practice, many students still have difficulty in developing ideas, exploring, and solving problems innovatively. Various previous studies have developed teaching materials based on Project Based Learning (PjBL) and Augmented Reality (AR) separately. However, none have integrated the two to improve scientific creativity. Based on the results of previous research studies, this study aims to develop student worksheets (LKPD) based on PjBL integrated with AR to improve the scientific creativity of high school students. The research method used is Research & Development (R&D) from ADDIE which consists of five stages, namely analysis, design, development, implementation, and evaluation. Based on the results of previous research studies, both in terms of methods, approaches and use of physics learning media, there is a research gap, the gap between this research and previous research is the integration between AR technology and project-based LKPD. The integration of AR with project-based LKPD simultaneously is something new in this study. This integration will provide a new experience that is more interactive and interesting in the physics learning process. The results of the study showed that the results of the validity test by three experts obtained an average validity score of 3.91 (98%) with a very valid category and a reliability score reaching 95.6% with a reliable category. Thus, this student worksheet is declared valid, practical, and effective in improving the scientific creativity of high school students. The limitation of this study is that this study has only reached the validation stage so that it needs to be implemented in more high schools.

Abstract

The utilization and processing of Family Medicinal Plants (TOGA) is part of the solution to overcome health problems. Among the family medicinal plants, turmeric and Javanese ginger have benefits as immunomodulators. The purpose of this activity is to Increase Student Knowledge About the Utilization and Processing of TOGA: Formulation of NUIGUM (Nutraceticals Immune Booster Gummy Candy) Turmeric Extract (Curcuma longa) and Javanese Ginger (Curcuma xanthorriza) as an Immune Booster with Variations of Adding Siwalan Sugar (Borassus flabellifer l). The method used is socialization and education on the importance of the benefits and processing of TOGA to students of grades X and XI Pharmacy as an indicator of Asta Cita science, technology and health. The results of this activity show an increase in the percentage of student knowledge from 10% to 85%. This community service is expected to open new business opportunities for students while supporting the achievement of Sustainable Development Goals (SDGs), namely a healthy and prosperous life.

Abstract

Albumin dan Protein merupakan salah satu tolak ukur terhadap penentuan malnutrisi terhadap status gizi manusia. Keduanya dapat mengidentifikasi apakah ada korelasi terhadap aktivitas siswa yang rutin sarapan pagi dan yang tidak. Penelitian ini bertujuan untuk menganalisis perbedaan tingkat konsentrasi siswa selama menempuh pendidikan dalam kelas yang diukur menggunakan observasional analitik desain cross-sectional dan kadar albumin dan protein serum siswa. Sebanyak 22 siswa skrining risiko malnutrisi menggunakan Subjective Global Assessment (SGA) dilanjutkan dengan wawancara. Kadar diambil dari serum siswa dan Analisis statistik menggunakan uji korelasi nonparametric test menggunakan SPSS 26. Terdapat perbedaan signifikan perubahan kadar albumin p=0.001 dan protein p=0.002 antara siswa yang sarapan pagi dan yang tidak (p<0.05). SGA mampu mendeteksi risiko malnutrisi pada 6 orang (27,3%) dan tidak berisiko manlutrisi pada 16 orang (48,4%), secara statistik albumin dan protein tidak signifikan berisiko malnutrisi dengan p-value 0.65 dan 0.70. Disimpulkan bahwa tidak ada hubungan bermakna antara siswa yang sering sarapan pagi dan tidak dengan kadar total protein dan albumin (p > 0.05), hanya saja ada penurunan konsentrasi pada saat kegiatan belajar mengajar terutama menjelang siang sekolah

Abstract

Matoa tree bark is a plant that contains flavonoid chemical compounds believed to be a traditional medicine in various alternative treatments. Therefore, it is important to measure its flavonoid content. Ethyl acetate extracts were prepared using the maceration method at durations of 3 x 24 hours. The aim of this study was to determine the flavonoid compound content and levels in matoa tree bark (Pometia pinnata) using UV-Vis spectrophotometry. Qualitative analysis was carried out using NaOH reagent and the wilstater cyanidin test, both of which showed positive results for containing flavonoid compounds, indicated by an orange color change. Quantitative analysis using a regression quercetin standard curve with an R2 value of 0,9844 revealed a flavonoid content of 2.712%. These results indicate that matoa tree bark extract has a high flavonoid content and has the potential to be developed as a herbal medicine formulation.
