Abstract

Discourse on the utilization of medicinal plants, which have the potential to be made into liquid soap and balsam, is very much needed for SMA and SMK students as knowledge in doing entrepreneurship in developing pharmaceutical products. Therefore, community service activities (PKM) are needed to provide knowledge and skills regarding the manufacture of liquid soap from basil and balsam extracts from Eucalyptus oil. The purpose of this PKM activity is to provide knowledge, understanding, and skills regarding the procedures for making liquid soap from extracts of basil and balsam leaves from Eucalyptus oil. This PKM activity includes the planning stages, such as making socialization flyers, materials, and videos on making soap and balm from natural ingredients. The implementation stage of providing materials and simulations for SMA/K children in Bekasi City at the STIKes Mitra Keluarga Pharmaceuticals Laboratory, Bekasi. The Evaluation Stage is in the form of taking a response score on the use of liquid soap and balsam by the PKM participants. The results of this PKM showed that there were 26 SMA/SMK students in attendance in Bekasi City, with 84.61% of SMK students dominating the participants. The preferred product was Balsam Eucalyptus oil, especially in terms of aroma, texture, and warmth. This PKM concludes that participants have a new understanding of the use of basil leaves and Eucalyptus oil for making liquid soap and balsam. The product that the participants liked was balsam Eucalyptus oil compared to basil leaf extract liquid soap.

Abstract

Respirasi adalah salah satu proses metabolisme (katabolisme), reaksi ini menggunakan oksigen untuk memecah senyawa-senyawa yang kompleks menjadi molekul-molekul sederhana seperti yang digunakan sel sebagai energi untuk bertahan hidup. Angiospermae adalah tumbuhan dengan biji tertutup dan biasanya menghasilkan bunga dan buah, sedangkan Gymnospermae adalah tumbuhan dengan biji terbuka. Penelitian ini bertujuan untuk mengetahui perbedaan laju respirasi, pengaruh lingkungan terhadap laju respirasi, peran struktur daun pada laju respirasi dan faktor-faktor yang mempengaruhi laju respirasi tumbuhan Gymnospermae dan Angiospermae.. Alat yang diperlukan untuk kegiatan ini ada timbang analitik, respirometer, beaker glass, pipet tetes, jarum suntik, dan tisu. Bahan yang diperlukan KOH, vaselin, meltilen blue, Oryza sativa, Mimosa pudica, Cycas rumphii, Pinus merkusii. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) dengan empat kali ulangan percobaan. Teknik analisis data yang digunakan adalah Analisis of Variance (ANOVA) untuk mengetahui perbedaan konsumsi oksigen dalam proses respirasi antara tumbuhan Gymnospermae dan Angiospermae. Hasil yang didapatkan rata-rata laju respirasi tumbuhan Gymnospermae 0,33 sedangkan Angiospermae 0,45. Kesimpulan penelitian ini adalah tumbuhan Gymnospermae memiliki laju respirasi yang rendah dibandingkan dengan tumbuhan Angiospermae.

Abstract

One of the instruments that is often not available for cell observation skills in high schools in Bekasi City is a microscope. Therefore, it is necessary to carry out community service activities (CSA) in the form of training in the use and maintenance of microscopes, making and observing cell slides, and cell observation documentation techniques for high school students in Bekasi City. This CSA method, based on Asset-Based Community Development (ABCD) and Participatory Action Research (PAR), involves planning integrated CSA programs offered to several high schools in Bekasi City. The implementation stage was carried out in 6 meetings (each meeting started from 08.00-16.00) by providing a pre-test, delivering materials, conducting a post-test, practicing microscope use, making and observing cell slides, and documenting cell slide techniques. The evaluation stage was carried out by processing qualitative and quantitative data. The results of this CSA include 30 students: 19 from Al-Muhtadin High School and 11 from Annida Al-Islamy, MA. Statistical analysis using paired t-tests produced a sig value. 0.01<0.05 or CS activities can significantly increase the average value of knowledge about microscopes, while the average value of the skills test is 76.92. This CSA concludes that providing microscope materials and training as a CS activity package can enhance the knowledge and skills of 19 Al-Muhtadin High School students and 11 Annida Al-Islamy MA students in observing cells using a light microscope.

Abstract

Introduction : Caffeine is an alkaloid compound that can be harmful to health if consumed in excess. One factor believed to influence caffeine levels in coffee is the processing method, particularly the roasting time. Therefore, this study focuses on the effect of varying roasting times on caffeine levels in coffee. Method: This study was conducted as a quantitative experimental study. Arabica coffee beans were roasted at 220 C for 10 minutes, 15 minutes, and 20 minutes, with green coffee beans (unroasted) serving as a control. The samples were analyzed by High-Performance Liquid Chromatography (HPLC) using a mobile phase of distilled water:methanol (75:25),  C18 column, a flow rate of 1 mL/min, and lamda max 273 nm. Caffeine content was determined using a verified HPLC analysis method. Result: The moisture content of green coffee beans roasted for 10 minutes, 15 minutes, and 20 minutes was 9.04, 1.93, 1.63, and 1.44, respectively. Caffeine content analysis was performed using a validated HPLC method. The average caffeine content of green coffee beans at roasting times of 10 minutes, 15 minutes, and 20 minutes, respectively, was 0.0065, 0.0096, 0.0088, and 0.0074. A significance value of 0.000 (p < 0.05) indicates a significant difference in caffeine content among the treatments, suggesting that roasting time affects the caffeine content in coffee. Conclusion: Differences in roasting time have a significant effect on the caffeine content of Arabica coffee, with changes showing an increase during the early stages of roasting, followed by a decrease as roasting progresses.
