Abstract

Kelangkaan bahan bakar dan tingginya emisi gas buang karbon monoksida merupakan masalah yang sering terjadi di Negara Indonesia sebagai akibat dari tingginya kebutuhan sarana transportasi. Dibutuhkan pencarian sumber energi alternatif baru yang dapat diproduksi secara massal sebagai solusi pengganti tingginya penggunaan bahan bakar fosil untuk bahan bakar kendaraan bermotor. Salah satu usaha yang dapat dilakukan yaitu pengolahan limbah sampah organik menjadi bioethanol. Pengolahan limbah sampah organik menjadi bioethanol sebagai bahan bakar sepeda motor adalah solusi tepat yang bisa dilakukan mengingat pengolahannya bisa dilakukan pada skala rumah tangga. Jenis penelitian yang digunakan adalah penelitian kuantitatif. Metode penelitian yang dipakai adalah metode eksperimen. Tujuan dari penelitian yaitu: 1) menyelidiki apakah ada pengaruh penggunaan bioethanol dari pengolahan limbah sampah organik terhadap kinerja mesin pada Sepeda Motor Honda Vario 150; 2) Menyelidiki seberapa besar pengaruh penggunaan bioethanol dari pengolahan limbah sampah organik terhadap kinerja mesin pada Sepeda Motor Honda Vario 150. Hasil penelitian menunjukkan terjadi penurunan emisi gas buang karbon monoksida (CO) dengan menggunakan bahan bakar bioethanol dari sampah organik sebesar 0,04. Terjadi kenaikan daya dengan menggunakan bahan bakar bioethanol dari sampah organik sebesar 0,03. Terjadi penurunan konsumsi bahan bakar dengan menggunakan bahan bakar bioethanol dari sampah organik sebesar 0,038.

Abstract

This community service program was initiated to address challenges faced by vocational high school teachers in Yogyakarta. The primary issue is the lack of teacher preparedness to implement differentiated learning models in English lessons. Teachers often lack confidence in their ability to design engaging and relevant learning scenarios for students with diverse characteristics. Additionally, there is a tendency among teachers to assess student skills and readiness uniformly, leading to suboptimal delivery of varied activities, materials, and resources that cater to individual learning styles and preferences. To address these challenges, a workshop was organized to enhance teachers' understanding and skills in differentiated English learning. The workshop aimed at improving the pedagogical competence of vocational high school English teachers in Yogyakarta was conducted between May and June 2024, both online and offline. The program included practical experience-sharing sessions, offline workshops, and online mentoring to review teaching modules created by 49 vocational high school teachers. These modules were based on differentiated learning principles tailored to vocational education. The teachers provided positive feedback on the workshop, indicating that they found the facilities and presentation of the material highly beneficial. The success of this workshop, centered on differentiated learning, underscores its impact on enhancing the pedagogical skills of vocational high school English teachers.

Abstract

Asia Tenggara dikenal dengan kekayaan budaya dan etnis yang beragam, namun kerap menghadapi konflik dan intoleransi antarkelompok. Kasus Rohingya menyoroti dampak negatif dari perbedaan ini, sering dibahas di platform Twitter. Untuk mengidentifikasi gambaran tentang penanganan Rohingya di Aceh, penelitian ini menggunakan metode KDD (Knowledge Discovery in Database). Proses ini mencakup seleksi, preprocessing, transformasi, data mining, dan evaluasi. Studi ini menunjukkan bahwa skenario 90:10 dengan pelabelan Inset Lexicon dan SMOTE menghasilkan akurasi model yang meningkat dari 80% menjadi 83%, dengan presisi 88%, recall 76%, dan f-measure 81%. Penggunaan Naïve Bayes untuk menganalisis sentimen dari 2.584 tweet Twitter menunjukkan hasil yang menjanjikan. Rekomendasi untuk penelitian mendatang mencakup pengumpulan data yang lebih luas dan pertimbangan algoritma seperti Random Forest atau Support Vector Machine. Pemerintah perlu mengadopsi kebijakan inklusif untuk memfasilitasi integrasi Rohingya di Aceh, sementara UNHCR harus meningkatkan advokasi dan kerjasama dengan pemerintah serta meningkatkan kesadaran masyarakat tentang integrasi pengungsi.

Abstract

This study is a case study held in one of the writing classes of semester two students of the English Language Education Study Program in one of the universities in Yogyakarta, Indonesia. The aim of this study this to know the process of students in writing acceptable descriptive texts in English through their reflective journal. This study is essential to be done because we need more insights on the process of writing acceptable descriptive texts for pre-service English teachers. In obtaining the data, the researcher provided a reflective journal template that must be filled in by the students in the process of writing the descriptive texts. The result of this study can be categorized into four different points which are 1) the outlining process of pre-service English teachers writing their descriptive texts; 2) the drafting process; 3) the review process; and 4) the finalization of writing acceptable descriptive texts. Hopefully, the result of this study can give more insights and improvements to the teaching and learning of how to write descriptive texts especially for pre-service English teachers.
