Gardu induk adalah peralatan yang sangat penting dalam menyalurkan energi listrik ke berbagai macam konsumen seperti pendidikan, industri, rumah sakit, dll. Energi lisrik tersebut disalurkan melalui saluran udara (overhead), sehingga menimbulkan permasalahan yaitu gangguan sambaran petir langsung yang dapat merusak sistem isolasi dan peralatan karena nilainya melebihi Basic Insulation System (BIL). Peralatan proteksi dibutuhkan untuk mencegah dan mengurangi gangguan sambaran petir langsung yang dapat menaikkan tegangan sistem. Arester jenis metal-oxide adalah peralatan proteksi yang saat ini banyak digunakan untuk melindungi dari sambaran petir dengan manyalurkan tegangan lebih ke tanah (ground). Pada penelitian ini dua tipe arester dibandingkan serta memodelkan peralatan yang ada pada gardu induk dengan menggunakan simulasi ATPDraw. Hasil simulasi menunjukkan bahwa arester tipe Q150NA121A mempunyai kinerja yang sangat baik dengan nilai tegangan lebih sebesar 458 kV. Sedangkan untuk arester tipe Q150NB121A nilai tegangan lebih masih cukup tinggi yaitu sebesar 585 kV.

This study aims to find out the differences in writing skills in elementary schools by using Mind Mapping based joy full learning models and determining the effectiveness of using Mind Mapping based joy full learning models in Indonesian writing skills. This research method is included in experimental research, which takes two groups as research samples. A quasi-experimental study was conducted on 30 elementary school students randomly assigned to the experimental or control group. The data collection method used is the writing skill test method. Before giving the writing activity, a pre-test was carried out. It continued the writing activity by using the experimental group's mind mapping model based on joyful learning. At the same time, the control class did not receive treatment using this model. Next, a post-test was conducted in both groups to determine the effectiveness of the joyful learning-based mind mapping learning model. The data analysis techniques were validity, reliability, normality, homogeneity, and t-test. Data analysis used the Independent Sample T-Test technique. The Independent sample t-test showed that the experimental group obtained a higher mean score than the control group. The results of this study indicate that T- arithmetic: 2.354> T-table: 2,000. It can be concluded that the teaching system using the Mind Mapping-based Joy full learning models was better than those that did not use the Mind Mapping-based Joyful learning models. The results of the data analysis are Mind Mapping-based joy-full learning models effectively teach Indonesian writing skills in elementary school. The recommendation of this research is for further research to modify the mind mapping learning model based on joyful learning to be more effective in improving writing skills in elementary school students.

The study aims to evaluate the effectiveness of the Problem-based Learning model in improving the students' ability to collaborate on practical activities related to the solution colligative properties. The research design uses quasi-experimental methods with control groups and experiments. The study sample consisted of 60 XI IPA class students selected using purposive sampling techniques, with 30 students in the experimental group and 30 in the control group. The research instruments include a test of collaborative abilities, a sheet of observations on collaborative activities, and an elevator of student responses. The results showed that the average pre-test scores of students' collaboration ability in experimental and control groups were relatively the same. Still, there was a significant improvement in the experimental group's post-test score after applying the Problem-Based Learning model. The pair t-test results showed a substantial improvement in both groups, but the increase in the experimental group was significantly higher (t(30) = 12.45, p < 0.05) compared to the control group (t(30) = 3.21, p < 0.05). Independent t-tests showed significant differences between the experimental and control groups after treatment (t(60) = 6.34, p < 0.05). Observations during the practice showed that students in the experimental group were more active in communicating, sharing tasks, collaborating, and solving problems than in the control group. In addition, the student response raise showed that the majority of students responded positively to the Problem-Based Learning model, with a high average score on interesting and enjoyable aspects (4.5), boosting motivation (4.6), facilitating the understanding of concepts (4.4), and enhance the ability to collaborate (4.7).

This study aims to develop a green synthesis method of silver nanoparticles (AgNPs) by utilising cassava (Manihot esculenta) peel waste extract and gelatin as reducing and stabilising agents for Surface-Enhanced Raman Scattering (SERS) applications. This synthesis technique promotes environmentally friendly principles by using natural materials that are easily available, cost-effective, and reduce the use of hazardous chemicals. The synthesis results show that the silver nanoparticles obtained have high stability and are able to increase the intensity of the Raman signal, allowing the detection of molecules at very low concentrations. Characterisation of AgNPs includes analysis using UV-Vis spectroscopy, TEM, XRD, as well as SERS performance measurements. This research shows that green chemistry-based synthesis methods can produce high-quality nanoparticles with high efficiency, so they have the potential to be widely applied in various chemical sensor applications that require high sensitivity.

Pembiasaan doa harian merupakan salah satu upaya penting dalam pendidikan agama untuk anak usia dini, terutama di lembaga PAUD. Namun, keterbatasan perhatian dan minat anak sering kali menjadi tantangan dalam metode pembelajaran konvensional. Begitupun pada PAUD Insan Muda mulia. Metode pembelajaran doa yang diterapkan masih menggunakan metode mendengarkan guru secara berulang. Anak-anak cenderung kurang tertarik apalagi yang memiliki fokus terbatas sehingga dibutuhkan metode yang lebih interaktif untuk mempelajari doa-doa harian. Dengan demikian, dikembangkan model pembelajaran berupa smart daily pray . Pada penelitian ini digunakan metode prototyping untuk membangun prototipe sebelum mengembangkan sistem secara keseluruhan, sementara metode kualitatif mendukung proses pengumpulan data dan analisis. Dari hasil pengujian yang dilakukan sistem dapat berjalan dengan baik sesuai dengan fungsionalitasnya. Dengan adanya sistem ini diharapkan dapat memberikan kontribusi penting dalam pengembangan media pembelajaran yang inovatif dan interaktif dalam membantu pembiasaan doa harian pada PAUD Insan Muda Mulia.
