Abstract

Sesuai dengan kewenangan Pemerintah Provinsi Sumatera Utara di bidang pertanahan, maka perlu dilihat lebih lanjut bagaimana peran pemerintah dalam proses penyelesaian permasalahan konfliks pertanahan. Konflik pertanahan yang berlangsung lama dan belarut-larut adalah sengketa/konflik lahan eks HGU PTPN II. Metode deskriptif digunakan untuk mendiskripsikan secara sistematis, faktual dan akurat terhadap penyelesaian permasalahan konfliks pertanahan. Hasil penelitian menunjukkan bahwa Pemerintah Provinsi Sumatera Utara melaksanakan kewenangannya yang penyelesaiannya terganjal sampai saat ini. Salah satu isi diktum dari SK BPN Nomor 42,43,43/2002 dan No. 10/204 yang memuat kalimat: menyerahkan Pengaturan, Penguasaan, Pemilikan, Pemanfaatan dan Penggunaan Tanah tersebut kepada Gubernur Sumatera Utara. Untuk selanjutnya diproses sesuai ketentuan peraturan perundangan yang berlaku, setelah memperoleh ijin dari Menteri. Permasalahan menjadi rumit, karena ijin tersebut tidak terbit sampai sekarang. Upaya untuk mencari solusi masih terus dilakukan termasuk dengan pemerintah pusat yaitu kementerian Dalam Negeri maupun Kementerian BUMN. Berdasarkan fakta lapangan, banyak kelompok masyarakat baik penuntut maupun pemohon juga perusahaan swasta yang saat ini menguasai lahan eks HGU PTPN II. Maka Pemerintah Provinsi Sumatera Utara harus sesegera mungkin mengadakan pendataan ulang dan verifikasi/permohonan yang disampaikan oleh kelompok masyarakat penuntut/pemohon, sehingga dapat diperoleh kebenaran yang seobjektif mungkin untuk memperoleh hak atas redistribusi tanah-tanah eks HGU tersebut.

Abstract

The lack of physics practicum equipment in schools is one of the reasons why practicum activities are rarely carried out, so many students still do not understand the physics concepts being taught. Therefore, one of the aims of this study is to apply two types of virtual practical media (PhET and NI Multisin simulations) and assess their effectiveness. This research uses a quasi-experimental approach with a non-equivalent control group design. In other words, the study utilized two experimental groups and one control group. All students in class 12 of high school from five localities comprised the research population, and a purposive sampling technique randomly selected a sample of three classes. So we got a sample of class 12-1 science for experimental group 1, class 12-2 science for experimental group 2, and class 12-3 science for the control group. After the testing prerequisites were met, the independent sample t-test at a significance level of 0.05 was used for data analysis. According to the data analysis results, there are significant differences in conceptual understanding between students in the control class, PhET class, and NI Multisim class. The research concludes that lecturers or teachers wishing to conduct virtual practicums in physics learning should utilize the NI Multisim simulation due to its ease of use and its more suitable facilities for the topic under study.

This sound absorbing material is made by mixing bagasse fiber and coconut coir fiber with a catalyst and resin solution which has been mixed, molded and left for 3-4 hours. The researcher also discussed the differences in the characteristics of coco fiber and bagasse fiber as sound absorbers. In this research, material analysis of bagasse fiber and coco fiber as sound absorbers was carried out. The results of the study indicate that coconut fiber has better sound-damping capabilities than sugarcane bagasse fiber at a frequency of 400 Hz. At a frequency of 1000 Hz, although both samples show a decrease in absorption coefficient, coconut fiber still performs better with a higher coefficient than sugarcane bagasse. It can be concluded that coconut fiber is more suitable for sound-damping applications across various frequencies, while sugarcane bagasse fiber is more effective for low-frequency sound absorption.   Keywords—Coconut Coir Fiber (Cocos nucifera L), Sugarcane Bagasse Fiber (Saccharum offinarum), Absorbing Coefficient, Sound Absorption, Frequency

Abstract

In fact, the physics learning process in senior high schools does not encourage students to think critically, resulting in low learning outcomes. This research aims to test the effectiveness of a scientific-based flipped class model to enhance students' critical thinking abilities. The research method used is a quantitative method with a quasi-experimental design, specifically nonequivalent pre-test post-test control group design. The population of this study consists of all tenth-grade science classes at Kutacane State Senior High School 3, and the sampling technique used is total sampling, where tenth-grade science class I serves as the experimental group, while the tenth-grade science class II serves as the control group. The instruments used are observation sheets, tests, and questionnaires. Data were analyzed using the N-Gain test, the classical completeness test, and student response analysis. The results of the study showed that critical thinking skills, as measured by both the classical completeness test and N-Gain test, improved in both classes, with the experimental class showing a high gain index category, while the control class showed a moderate gain index category. Learning using a scientific-based flipped class model is effective in enhancing students' critical thinking abilities because it can facilitate students in accessing the provided learning materials.
