Moreover, it has become a common trend among undergraduates to carry a mobile gadget to the classroom as well.In this paper, the researcher emphasize the potential of mobile gadgets as a learning tool for students and have incorporated them into the learning environment.The present study examines the application of mobile gadgetin EFL learning and investigates the perceptions of EFL students about mobile gadget in learning activity. A field study was conducted on thirty undergraduatestudents majoring in accounting study Serang Raya University. The methodology of data collection included a self-report for students and teachers’ and students’ questionnaire.

This research aimed to improve active learning through students' PowerPoint presentations in the first grade students of nursing class of Private Vocational High School Serang City 2015/2016 academic year. The method used was Classroom Action Research which consists of planning, acting, observing, and reflecting. The study was carried out in three cycles and the data of this study was gathered through: (1) Student' presentations, (2) observations, and (3) students computer use survey. The results showed that there was improvement of active learning in the teaching and learning process of nursing class students. In the first cycle, 62,5% of 32 students performed their presentation poorly. Some causes, students were not familiar to practice oral presentation in English, 25% did their presentation satisfactorily and only 12,5% of them performed pretty good presentation in the classroom. After intensive classroom and practices, in cycle II explained that 40,63% students did their presentation poorly. 33,3% could present their topics satisfactorily and 28,13% students performed much better and some of them did their presentation with their better way. Cycle III revealed clearly that students speaking skills were getting better after they were given additional time for much practices on how to deliver a good presentation and operate computer program. It can be seen 21,8% students performed satisfactorily, 40,6% students presented their good performance, and 37,5% did their best performances in delivering English presentation.
The study attempted to design reading materials for Medical Science at one of Vocational High Schools Medical Science in Serang. To produce satisfactory teaching materials, the researchers did the following steps: doing needs analysis, reviewing the principles of materials design and reading in a foreign language, designing course framework, designing syllabus, designing the reading materials, and implementing the sample lessons. The researchers employed qualitative methods in gathering the data. The instruments used were questionnaire and interview. The questionnaire was addressed to students, alumni, teachers and institution. The interview was collected from the companies or users that have ever recruited the graduated students. The needs analysis was carried out by distributing questionnaires. The results were then analyzed. The result of needs analysis, became the basis for the researchers to design course framework. The course framework was then developed into a syllabus. Finally the syllabus became the basis for designing reading materials. The reading materials for Vocational High School Husada Pratama applied a topical syllabus. Each lesson or unit had different topics, greeting and introduction. Introduction about nurse, health, dioalogue conversation nurse and patient, eat healthy food, profile a nurse, tools, disease, nutrition, the healthy diet pyramid. Each lesson also adopted various reading skills or strategies. They were skimming, scanning, and guessing meaning from context. When the materials had been designed, the researchers implemented six out of ten lessons of the coursebook. The results were satisfactory. Most students mentioned that the coursebook was related to their field of study. The majority of the students also said that the materials were understandable and interesting. They also said that they were satisfied with the reading materials. Keywords: Reading materials, ESP, Reading skill
Based on data from PLN, in 2020 the number of PLN customers has reached 77,19 million or increase of 3.59 million customers compared to 2019 which amounted to 73,6 million customers. Along with modernization in Indonesia, without realizing it there is still a lot of wasted electrical energy from electronic devices that are left on standby and not used or electric vampires. The purpose of this research created a tool to overcome the problem of electric vampires in electronic equipment in order to reduce the number of losses below the national electric losses of 8%. The implementation method used for the design and manufacture of the Electric Vampire Remover is the Research and Development (R&D) research method. The steps taken are: 1) analysis of tool requirements, 2) design of tool, 3) manufacture of tool in the laboratory, 4) testing of tool functions and performance, 5) concluding the results. These stages are conducted in cycles to get the best result. The result of the research is the creation of an Electric Vampire Remover which is functionally proven to be able to control electrical equipment properly. This tool can be operated stand-alone or based on internet network. The results showed that the tool was able to reduce losses caused by electric vampires by 99%. The application of this tool at home is able to save 36,908 kWh which is equivalent to Rp. 53,320.99/month in the fare class or R-1/1300 VA power.
Penelitian ini bertujuan untuk mengetahui kandungan senyawa metabolit sekunder dan antioksidan serta antidiabetes ekstrak diklorometan dan etil asetat daun mangrove Rhizopora mucronata. Tumbuhan sampel yang digunakan diambil di pesisir pantai Muara Badak. Sampel daun mangrove R. mucronata yang telah dikeringkan diekstrak dengan metode maserasi menggunakan pelarut methanol dan dilanjutkan dengan proses ekstraksi secara partisi cair-cair menggunakan pelarut n-heksan, diklorometan dan etil asetat. Ekstrak diklorometan dan etil asetat daun mangrove Rhizopora mucronata dilanjutkan dengan uji fitokimia menggunakan uji warna, uji aktivitas antioksidan dengan metode DPPH, uji antidiabetes menggunakna metode uji toleransi glukosa oral (UTGO). Hasil uji fitokimia ekstrak diklorometan dan etil asetat daun mangrove Rhizopora mucronata positif mengandung senyawa metabolit golongan alkaloid, flavonoid, tannin, dan fenolik. Hasil uji aktivitas antioksidan dari ekstrak total diklorometan memiliki nilai IC50 sebesar 70,38 ppm dan hasil uji antidiabetes berdasarkan persentase penurunan kadar glukosa darah mencit yang paling tertinggi terjadi pada mencit kelompok V dengan dosis 250 mg/kgBB yaitu sebesar 68,78%. Hasil uji aktivitas antioksidan dari ekstrak total etil asetat memiliki nilai IC50 sebesar 59,89 ppm sedangkan untuk hasil uji antidiabetes ekstrak etil asetat berdasarkan persentase penurunan kadar glukosa darah mencit yang paling tertinggi terjadi pada mencit kelompok IV dengan dosis 125 mg/kgBB yaitu sebesar 28,89%. Berdasarkan data tersebut dapat dikatakan bahwa ekstrak total diklorometan dan etil asetat memiliki aktivitas antioksida dengan kategori kuat. Ekstrak diklorometan berpotensi sebagai antidiabetes karena mampu menurunkan kadar glukosa dengan persentase penurunan kadar glukosa yang tertinggi.
