This research aimed to examine the potential of waste from controlled landfills a raw material for a Waste-to-Energy (WtE) plant. The research employed the qualitative method with direct observation. Data were analyzed descriptively. The results showed that the composition of waste in Cirebon was mostly dominated by household food waste (52.41%), followed by plastic (15.58%) and paper (8.05%). Based on the amount of existing waste and the projected amount in Cirebon City and Cirebon Regency, the waste can potentially be used as raw material for WtE plant. The energy generated from this waste can be sold to PLN, creating a positive utilization of the waste. It is projected that Cirebon City will produce 1319 m3/day of waste, and Cirebon Regency will produce 4767.65 m3/day (1161.26 tons/day) in 2023. Therefore, further research is needed to develop appropriate, efficient, and environmentally friendly technology for the municipal solid waste management system in Cirebon.

This study aims to evaluate the use of interactive e-modules based on Somatic, Auditory, Visual, Intellectual (SAVI) in the learning process with light material. Several multimedia aspects are presented in this interactive e-module (such as video, sound, picture, etc.). To collect relevant information, this descriptive research involved 27 students grade 8 from a State Islamic Junior High School in Kediri. A valid and reliable User Experience Questionnaire (UEQ) was use to examine students’ experience while using SAVI-based interactive e-module. The SAVI-based interactive e-modules received good responses for each user experience questionnaire indicator. The good response from the students showed that the SAVI-based interactive e-modules was good to use in learning process.

This study aims to analyze the effect of immersion time and current strength on the quality of the Ag layer, namely the mass, thickness and surface morphology of the best coating results. The electrode used was copper in the shape of a cylinder with a size of 5x0.2 cm and the electrolyte solution used was silver nitrate solution (AgNO3). The electroplating process in this study was carried out at 12 volts, with variations in electric current 4A, 6A, 8A for 30 minutes of immersion time and electrolyte concentrations of 0.6 M, 0.3 M and 0.1 M. Morphological characterization of the coated copper surface silver using SEM instruments. The results of the study obtained the sample with the best results from the weight value of the precipitated Ag metal, the thickness of the layer formed, namely copper samples treated (0.28 M, for 30 minutes). From the results of the SEM photos on the Cu/Ag surface, it can be seen that the samples electroplated for 30 minutes already contained a collection of small to medium lumps and the surface looked smooth and there were few pores on the copper surface resulting from silver electroplating.

This study aims to analyze students' misconceptions and explain their reasons for material misunderstandings about the human respiratory system. This research is a quantitative study which was attended by 21 class VIII students in one of the schools in Sukabumi Regency. The instruments used are two tier test equipped with CRI (Certainty of Index), student responses to the differentiation-based learning model Multiple Intelligences . The results of the interviews showed that students had misconceptions about the respiratory system material which consisted of organ structures and their functions, mechanisms and respiratory diseases in humans 36.90%, while when grouped into 3 groups showed students got misconceptions in kinesthetic children 37,50%, children linguistics 37,50% and visual children 35,42%. The conclusion from the results of this discussion is that the factors that cause misconceptions to occur are students arguing with their own beliefs, and teaching methods.

Mobile and immovable educational facilities and infrastructure are very important for the teaching and learning process and enable the completion of educational goals in an orderly, efficient, effective and timely manner. The learning process is an activity in which there is interaction between educators and students as well as reciprocal communication that takes place to achieve learning objectives. Factors that can influence the learning process to be effective and efficient, such as teacher, student, facilities and infrastructure as well as environmental factors. The method used in this research is descriptive analysis method. The purpose of this study was to determine the level of student satisfaction with facilities and infrastructure in one of the study programs at Fatmawati Sukarno Bengkulu State Islamic University in supporting the learning process. From the results of student satisfaction with the facilities and infrastructure to support the learning process, namely for classrooms, chairs, tables and blackboards, they stated that they were 100% satisfied. Laboratories 86% satisfied and 14% unsatisfied, for prayer rooms 70% satisfied and 30% unsatisfied. Trash box 44% satisfied and 56% dissatisfied, toilet 98% satisfied and 2% dissatisfied, projector 34% satisfied and 66% dissatisfied, fan 88% satisfied and 12% unsatisfied.

Minat belajar siswa yang rendah serta suasana belajar yang kurang nyaman dan kurang bermakna dapat mempengaruhi minat belajar siswa. Sebagian besar guru saat ini sangat jarang menggunakan media pembelajaran, guru cenderung fokus pada satu sumber yaitu buku, sehingga siswa sulit memahami materi yang abstrak. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh media interaktif berbasis video terhadap minat belajar siswa sekolah dasar. Penelitian ini menggunakan jenis penelitian kuantitatif dengan desain eksperimen (Posttest Only Control Design). Populasi yang digunakan meliputi sebanyak 52 siswa Kelas V SDN Jimbaran Kulon, teknik pengumpulan data berupa angket, observasi dan dokumentasi. Teknik analisis yang digunakan adalah uji-t (t-test). Hasil analisis data menunjukkan nilai signifikan lebih besar dari 0,05 dan nilai signifikansi uji t sebesar 0,000 yang berarti ≤ 0,05. Dapat disimpulkan bahwa media interaktif berdampak pada minat belajar IPA siswa kelas V SD Negeri Jimbaran Kulon.
学生学习兴趣不高，学习氛围不舒服，学习意义不大，都会影响学生的学习兴趣。如今，大多数教师很少使用学习媒体，教师往往只关注一个来源，即书本，这样学生就很难理解抽象的材料。本研究旨在确定视频互动媒体对小学生学习兴趣的影响。本研究采用实验设计的定量研究类型（仅后测对照设计）。研究对象包括金巴兰库伦 SDN 第五班的 52 名学生，数据收集技术包括问卷调查、观察和记录。采用的分析技术是 t 检验。数据分析结果显示显著值大于 0.05，t 检验的显著值为 0.000，即 ≤ 0.05。由此可以得出结论，互动媒体对金巴兰库伦学校五年级学生学习科学的兴趣有影响。
