Kajian Perencanaan Sistem On-Grid Berbasis Solar Photovoltaic Menggunakan Perangkat Lunak Homer Pro
Get PDFPenggunaan sistem fotovoltaik (PV) yang terhubung dengan jaringan menjadi strategi yang diadopsi secara luas untuk mengurangi emisi karbon dioksida dan biaya listrik. Sejalan dengan Peraturan Pemerintah No. 79 tahun 2014, Indonesia telah menetapkan target nasional untuk menggunakan 23% energi terbarukan pada tahun 2025. Sebagaimana diuraikan dalam Kebijakan Energi Nasional (RUEN), Indonesia bertujuan untuk mencapai total 45 GW kapasitas energi terbarukan pada tahun 2025, dimana 6,5 GW (14%) diproyeksikan bersumber dari energi surya. Penelitian ini menyajikan desain sistem PV atap on-grid di Masjid Al-Hikmah, Universitas Muhammadiyah Palembang (Kampus A), yang dimaksudkan untuk mengoptimalkan penggunaan energi dan mengurangi pengeluaran listrik. Berdasarkan simulasi yang dilakukan menggunakan Homer Pro, sistem yang diusulkan terdiri dari 48 modul surya dengan total kapasitas 20 kWp, yang diintegrasikan dengan inverter on-grid Growatt tiga fase. Hasil simulasi memperkirakan produksi energi tahunan sebesar 27.306 kWh, dengan sistem PV memasok 57,7% dari total kebutuhan energi, dan 42,3% sisanya (19.985 kWh/tahun) bersumber dari jaringan listrik umum. Analisis ekonomi, dengan menggunakan tarif listrik Rp 992,72 per kWh, menunjukkan bahwa investasi ini layak secara finansial, dengan periode pengembalian modal yang diproyeksikan terjadi pada tahun ke-21 operasi
Analysis of School Readiness in Developing School Digitalization at MA Al Hikmah Kajen
Get PDFThis research aims to analyze the readiness of MA Al Hikmah Kajen in developing school digitalization, focusing on infrastructure, digital competence of teachers and students, principal's leadership, and obstacles. Digitalization is crucial for education quality, yet many institutions face implementation challenges. MA Al Hikmah, a madrasah in a pesantren environment, uses digital components like online admissions and virtual classrooms, but their daily application is limited by internal policies restricting student device use. Using a descriptive qualitative approach with interviews, observation, and documentation, the study found commendable infrastructure readiness. Teacher competence shows progress but is uneven, especially among senior educators. The principal's leadership positively supports digitalization, though more adaptive policy encouragement is needed. Key impediments are the student gadget ban and persistent digital literacy limitations among some teachers. The research recommends flexible policies, continuous digital training, and cultivating a digital ecosystem aligned with pesantren values

CODE MIXING ANALYSIS IN THE ANGRY COMMUNITY ON TWITTER
Get PDFThis research seeks to explore the phenomenon, types, and underlying reasons for the use of two languages (code mixing) within the "angry" community on Twitter. Employing a qualitative descriptive approach with a digital ethnography method, the study collects data through observation, interviews, and field notes. The primary data sources include five tweet threads that demonstrate the use of two languages, as well as interview responses from five community members to investigate their motivations for using code mixing on the platform. The analysis identified two types of intra-sentential code mixing: insertion (at the word level) and alternation (at the phrase level). Most instances involved the incorporation of English words or phrases within Indonesian sentences. Based on the interviews, three key reasons emerged for this code mixing: habitual use of both languages in daily life that extends into online communication, a tendency to imitate peers who mix languages, and the desire to practice and enhance their second language proficiency
THE USE OF WORDWALL MEDIA TO IMPROVE STUDENTS’ VOCABULARY AT TENTH GRADE OF SMK NEGERI 1 SITOLUORI
Get PDFThis study explored the effectiveness of Wordwall Media in enhancing vocabulary acquisition among tenth-grade students at SMK Negeri 1 Sitoluori through a Classroom Action Research (CAR) approach conducted over two cycles. The findings revealed a marked improvement in vocabulary, assessed across three domains: spoken, written, and meaning. Initial pre-test scores showed averages of 52.72 (spoken), 29.63 (written), and 28.63 (meaning). In Cycle I, scores rose to 73.63 (spoken), 75 (written), and 49.09 (meaning), and further improved in Cycle II to 84.09 (spoken), 86.81 (written), and 84.09 (meaning). The use of Wordwall Media significantly supported vocabulary development by offering interactive and visually engaging content, such as animations and images, which enhanced student comprehension and motivation. The study concludes that integrating Wordwall Media into English instruction effectively addresses students’ vocabulary challenges. Teachers are encouraged to adopt this tool consistently to foster a more dynamic and effective learning environment
SURFACE LINGUISTIC ERRORS IN ORAL PRESENTATION: A CASE STUDY OF SECONDARY STUDENTS IN 3T REGION KUPANG TIMUR
Get PDFThis study examines the types and frequency of surface linguistic errors in English oral storytelling by junior high school students from the 3T (frontier, outermost, disadvantaged) region of Kupang Timur. Using a quantitative approach, data were collected from 15 students and analyzed through Dulay et al.’s Surface Strategy Taxonomy, with error analysis following Ellis’s framework: identification, description, explanation, and evaluation. The results show that omission errors were most frequent (47%), followed by addition (27%), misformation (20%), and misordering (6%). Frequent mistakes included the omission of “to be” verbs and possessive apostrophes, indicating limited mastery of basic English grammar in spoken form. These findings highlight the specific grammatical challenges faced by learners from remote, under-resourced areas. The study offers valuable implications for English language instruction, suggesting the need for targeted teaching strategies and curriculum development that address the unique needs of students in 3T regions. By focusing on an underrepresented group in Indonesian educational research, this study provides new insights into how linguistic background and educational access shape oral language proficiency, advocating for more inclusive and context-sensitive language teaching practices
