E-module is one of the media that is considered efficient to be used as a learning media. This research describes the e-module of addictive substances integrated with Islamic values as a solution in preventing and reducing addictive substance abuse, especially among adolescents, by providing scientific knowledge related to religious knowledge. The study aims to analyze the characteristic of e-module and validation results. The emodule is designed with the Design-Based Research (DBR) method with the three steps: analysis, design, and development. Based on the results, the e-module display Islamic views and their interpretation, animated videos, questions, attitude tests, and games. The validation result indicates that the e-module is valid and feasible to be used as a learning media.

Telah dilakukan penelitian yang bertujuan untuk menganalisis peningkatan hasil belajar siswa pada konsep sistem koloid dalam pembelajaran melalui media animasi. Penelitian ini merupakan jenis penelitian tindakan kelas yang ditempuh dalam dua siklus. Setiap siklus terdiri dari empat tahap yaitu tahap perencanaan, pelaksanaan, pengamatan, dan refleksi.  Subjek penelitian adalah 33 orang siswa SMKN 2 Cimahi kelas XI Teknik Kimia Industri. Teknik pengumpulan data menggunakan tes tertulis, angket dan observasi. Berdasarkan analisis data, pada siklus I diperoleh ketuntasan belajar 77,22 % (nilai rata-rata 68,97), sedangkan pada siklus II diperoleh ketuntasan belajar 84,85% (nilai rata-rata 74,18). Aktivitas siswa dalam pembelajaran menunjukkan peningkatan yang positif, karena perilaku yang tidak diharapkan di kelas semakin berkurang, sedangkan perilaku positif semakin meningkat. Dengan demikian dapat disimpulkan bahwa penggunaan animasi dapat meningkatkan hasil belajar kimia siswa pada materi koloid.

This study aims to describe the use of Instagrambased flipped classroom models in enhancing higher order thinking skills in buffer solution materials. Data were collected and analyzed using the pre-experiment technique while observation sheets were the instruments used. The research was made up of 38 Chemistry Education Study students. The results showed that on average student's activities at home is in the excellent category, while their class activities are tagged good. The results of the posttest value analysis were higher than the pretest in the medium category. This means that there is an increase in higher order thinking skills after the implementation of an Instagram-based flipped classroom learning model.

Penelitian ini bertujuan untuk mendeskripsikan profil manajemen dan penggunaan laboratorium pada pembelajaran kimia, meliputi kelengkapan dan penataan alat bahan praktikum, manajemen administrasi dan efektivitas penggunaan laboratorium kimia. Mengingat laboratorium sebagai penunjang pembelajaran kimia juga berperan penting dalam membangkitkan motivasi belajar dan pengembangan keterampilan dalam praktikum. Penelitian ini menggunakan metode deskriptif menggunakan pendekatan kualitatif. Subjek penelitian terdiri dari 2 SMA Negeri dan 1 SMA Swasta di wilayah Sumedang. Pengumpulan data menggunakan metode observasi, angket, dan wawancara. Analisis data menggunakan teknik persentase dengan analisis deskriptif kualitatif. Berdasarkan hasil penelitian, ketersediaan alat praktikum kimia di SMA wilayah Sumedang tergolong kategori lengkap (69,67%) dengan kondisi sangat baik (96,6%), namun ketersediaan bahan praktikum kimia tergolong kategori kurang lengkap (45,3%) meskipun dalam kondisi sangat baik (95%). Penataan alat praktikum kimia tergolong kategori sangat baik (81%), sedangkan penataan bahan praktikum tergolong kategori baik (71%). Administrasi alat bahan praktikum tergolong kategori kurang lengkap (48,6%), namun penggunaanya sangat efektif (100%). Administrasi ketenagakerjaan tergolong kategori sangat lengkap (76%). Efektivitas penggunaan laboratorium di SMA wilayah Sumedang tergolong kategori kurang efektif (42,4%). Faktor  penyebabnya terkait dengan kelengkapan, penataan serta administrasi alat bahan laboratorium dan penjadwalan, selain itu dari sudut pandang guru kimia terkait penting atau tidaknya praktikum dilaksanakan pada beberapa materi.

One of the efforts company did continuously to compete was to reduce waste or anything that is not adding value to products such as waiting activity that cause unbalance of workload between workstations on a production path. This condition resulted in idle work station, accumulation of intermediate goods, and low work station utility. Companies finds an unbalance workload. This work station are apparently have to wait in a given time after workstations does behind it finished. For that reason, this study aims to balance the workload between workstations and increase the company production capacity. This research uses simulation approach by modelling the initial production with software promodel and evaluate performance the the initial production with an indicator current content, output, and average time in operation. The performance of the initial production line model was the smoothness index of 2007.5, the current content of 10 units, the output of 34 units, and the average time in operation of 35.19 minutes. The alternative model of the selected production trajectory is due to excel in four track performance factors is lowest current content (1 unit), highest output (48 units), lowest smoothness index (461,8) and highest production capacity (9,12 unit/hour).
