Abstract

Small-scale gold mining (SSGM) using mercury remains prevalent in several regions of Indonesia, including Kalirejo Village, Kulonprogo Regency. This practice poses significant legal, environmental, and health issues. This study aims to analyze the legal aspects of SSGM, particularly concerning environmental regulations, public health protection, and the legal responsibility of miners. A normative juridical approach combined with a field case study was used to examine mercury usage practices, their impacts, and law enforcement at the local level. The findings reveal that although regulations such as Law No. 32 of 2009 on Environmental Protection and Management and Ministry of Environment Regulation No. 29 of 2013 on Emission Standards exist, their enforcement remains weak in practice. Mercury use has been proven to degrade environmental quality, contaminate soil and water, and cause severe health problems such as neurological disorders and organ damage in surrounding communities. This study emphasizes the importance of strengthening law enforcement, providing mercury-free gold processing technologies, and raising public awareness as mitigation measures.

Abstract

Indonesia, once a prominent oil-producing country and a member of the Organisation of the Petroleum Exporting Countries (OPEC), has experienced a decline in oil production over the past decade, despite a rising domestic demand for oil. The primary purpose of a corporation is to generate profit from its business operations. For an oil and gas corporation, profit is derived from the extracted oil. To attain oil production and profitability, a corporation will establish a key performance indicator (KPI) to assess its capacity to meet specified objectives. Crystal deposits from scale create impediments and elevate pressure loss, resulting in diminished oil output. The Scale problem significantly contributes to production losses, impacting output achievements from 2022 to 2024, resulting in a total loss of 98,946 barrels of oil. The Analytic Hierarchy Process (AHP) is a multi-criteria decision-making methodology used in this research to obtain the best alternative to diminished the problem. By using the AHP method, company can obtain the big revenue and avoid losses based on the priority and criteria.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran role playing berbantuan media wayang kertas terhadap keterampilan menyimak siswa kelas 3 SD Negeri 1 Aikmel Barat. Penelitian ini merupakan penelitian kuantitatif dengan jenis penelitian eksperimen berbentuk pre-eksprimental dengan desain yang digunakan adalah one group pretest-posttest. Pengambilan sampel dilakukan dengan cara teknik sampling purposive. Subjek penelitian ini terdiri dari 20 siswa. Instrumen penelitian yang digunakan berupa tes pilihan ganda, observasi dan dokumentasi. Teknik Analisis data yang digunakan pada penelitian ini meliputi uji validitas instrument, reliabilitas instrument, uji normalitas dengan Shapiro wilk serta uji hipotesis menggunakan paired-sample T Test. Pada analisis deskriptif tes keterampilan menyimak siswa memperoleh rata-rata pretest 51,30 sedangkan rata-rata nilai posttest meningkat menjadi 78,35. Berdasarkan Hasil uji normalitas menunjukkan nilai p-value >0,05 pada pretest maupun posttest, hal tersebut menunjukkan kedua data berdistribusi normal. Dari hasil perhitungan uji hipotesis apabila nilai sig < 0,05 maka terdapat pengaruh variabel x terhadap variabel y. setelah dilakukan uji paired sample T Test untuk keterampilan menyimak siswa telah diperoleh hasil sig. (2-tailed) 0,001 < 0,05 yang artinya terdapat pengaruh. Dengan demikian, hipotesis yang diajukan dapat diterima yaitu “” ditolak, sedangkan “” diterima, yang berarti adanya pengaruh model pembelajaran role playing berbantuan media wayang kertas terhadap keterampilan menyimak siswa pada materi teks narasi kelas 3 di SD Negeri 1 Aikmel Barat.

Abstract

This research explored the application of the Interactive Reading Approach (IRA) in the teaching of narrative texts to eighth-grade students at SMP Negeri 30 Bengkulu Tengah. The study was carried out in response to students’ low reading comprehension and the lack of active interaction during English lessons. It aimed to portray how IRA was implemented in the classroom, analyze patterns of interaction between teachers and students, and identify challenges encountered  throughout the learning process. Using a qualitative descriptive design, the data were collected  through classroom observations, semi-structured interviews with both teachers and students, and relevant documents, and were analyzed through coding, thematic analysis, and triangulation. The results indicated that IRA was conducted through a series of pre-reading, while-reading, and post-reading activities, which promoted students’ active involvement in interpreting narrative texts through discussion and guided support from the teacher. Although challenges such as limited vocabulary mastery, uneven student participation, and limited learning resources were encountered, the findings suggest that the Interactive Reading Approach contributed positively to classroom interaction and supported students’ reading comprehension.
