This research aims to develop an instrument for assessing understanding distance and displacement concepts. Distance and Displacement Inventory (DDI) is an instrument constructed in multi-representations, including picture, table, graphic, mathematical, and verbal representations. This instrument is in multiple-choice format with ten questions to assess students' understanding of distance traveled and displacement. DDI development refers to R&D design by Borg&Gall and test development flowchart by Beichner. DDI was applied to 357 students in Indonesia who had taken introductory physics courses. Student answers were analyzed to determine the DDI's psychometric properties and structural analysis. The analysis results show that the DDI is adequate for assessing students' understanding of travel distance and displacement concepts. Meanwhile, the structural analysis of students' knowledge results shows that students have different perceptions of each question item according to their representation. Furthermore, students who understand the concept of distance traveled and displacement in one representation may need help understanding it correctly in another representation. This research implies the necessity of designing learning designs based on multi-representations and teaching students about the changes between these representations.

ABSTRAKKetersediaan bahan bakar fosil yang semakin langka berakibat pada kenaikan harga BBM, oleh karena itu diperlukan suatu energi alternatif untuk mengurangi penggunaan bahan bakar minyak. Salah satu energi alternatif tersebut yaitu dengan penggunaan energi biomassa. Dalam penelitian ini biomassa yang digunakan adalah ampas kelapa. Tujuan dalam penelitian ini yaitu memanfaatkan ampas kelapa secara optimal dengan memfokuskan pada uji kualitas kadar air briket berbahan arang ampas kelapa. Penelitian ini menggunakan sampel barupa arang ampas kelapa dengan prosedur kerja meliputi proses pengeringan ampas kelapa, kemudian proses karbonisasi, penggilingan dan penyaringan, pencampuran bahan perekat, pencetakan dan pengeringan dengan menggunakan oven dengan suhu 100oC, dan penentuan mutu briket berdasarkan kadar airnya. Kadar air mempunyai peran besar terhadap mutu suatu produk. Nilai kadar air rata-rata yang diperoleh pada penelitian ini nilai di bawah 8 % pada sampel nomor 1, 2 dan 3 yang memiliki nilai kadar air berkisar antara 4% - 6%, berdasarkan nilai kadar air ini sehingga dapat diketahui bahwa kuliatas briket yang di hasilkan memiliki kualitas yang bagus, briket dengan kadar air di bawah 8%. Sedangkan untuk sampel nomor 4,5 dan 6 memiliki nilai kadar air yang berkisar antara 9% - 13 %, berdasarkan nilai kadar air yang diperoleh, maka dapat di identifikasi bahwa briket nomor 4, 5 dan 6 memiliki kualitas yang kurang bagus. Briket dengan kadar air tinggi agak sulit utuk dinyalakan, hal ini berakibat akan menghambat proses pembakaran.

Understanding physics concepts remains a focal point of education, continually researched and sought for appropriate solutions, especially in teaching strategies. The teaching strategies employed vary greatly in influencing students' understanding of concepts. The aim of this research is to identify effective solutions in enhancing students' understanding of physics concepts, based on data obtained from various relevant journals from 2010 to 2022. This study was conducted using the Systematic Literature Review (SLR) method, utilizing databases such as ERIC, Journal of Education Research, British Education Journal, and other journals indexed by SINTA to identify, review, evaluate, and interpret available research. The results indicate that an effective teaching strategy to enhance students' understanding of concepts is Problem-Based Learning (PBL).

The issue of environment and sustainable energy are two issues that have not been completely resolved until today. Liquid waste treatment technology, which can remove pollutants and produce hydrogen gas, is interesting to study since hydrogen itself is one of the energy sources whose use has begun to be developed. Aim: The following article will discuss several aspects that can be developed in each technology. Methodology and Results: Electrocoagulation and photocatalyst are both technologies which are possible to eliminate liquid pollutants while producing hydrogen in a single process. Research that attempts to combine two processes to improve the ability to treat pollutants in wastewater while producing hydrogen has been carried out. The optimization process can be carried out respectively in terms of electrocoagulation and photocatalytic technology. Modifications can also be made by combining the two processes of electrocoagulation and photocatalysis, either sequentially or simultaneously. Modification process carried out aims to increase hydrogen recovery without neglecting the ability of electrocoagulation and photocatalysis in removing organic waste. Conclusion, significance, and impact of study: This brief review provides an overview of the potential of electrocoagulation and photocatalysis technology in its ability to remove liquid waste while producing hydrogen gas. The opportunity to combine the two processes is also shown based on previous studies. The review is carried out based on an in-depth study of the research that has been done. The simultaneous use of both processes has been shown to provide much better capabilities in terms of removing liquid waste and producing hydrogen gas.

ZONASI POTENSI RAWAN GERAKAN TANAH DI KECAMATAN WATES KABUPATEN BLITAR DENGAN METODE STORIE Chusniyah, Dina Asmaul; Yudianto, Didik

Publisher : Universitas Mataram

Lokasi Kecamatan Wates terletak di Kabupaten Blitar bagian Selatan yang memiliki satuan morfologi perbukitan sedimen dengan bukit bergelombang dan kemiringan landai yaitu antara 10-30% yang membentuk punggung bukit tidak teratur.Metode desk studyÂ merupakan suatu metode yang dilakukan untuk mengumpulkan data maupun informasi secara sekunder. Pada data sekunder dilakukan analisis tumpang susun (overlay) dengan Sistem Informasi GeografisÂ (SIG).Hasil penelitian ini berupa peta rawan gerakanÂ tanah, peta ini diperoleh dariÂ overlayÂ antara beberapa peta, yaitu peta geologi,Â peta curah hujan,Â peta topografi, peta kemiringan lereng,Â dan peta pengembanganÂ lahan. Dari hasil overlay tersebut diperoleh proses penggabungan beberapa peta tematik dengan area yang sama dan menghamparkan satu dengan yang lain untuk membentuk satu layer peta baru yang memberikan informasi mengenai beberapa lereng, mulai dari lereng 15%-20%hingga lereng >40%, dengan curah hujan antara 1500-2000 mm/tahun hingga >2000 mm/tahun. Daerah tersebut di kelompokkan menjadi zona gerakan tanah rendah, sedang dan tinggi.Â Warna hasil overlayÂ peta ditentukan oleh besar intensitas pixel penyusunnya. Warna ini diperoleh dari besar kecilnya intensitas cahaya yang ditangkap oleh sensor. Karena intensitas cahaya di alam (gradasi intensitas analog) tidak terbatas dan belum ada alat yang mampu menangkap seluruh gradasi warna sehingga dilakukan proses kuantisasi yaitu suatu proses transformasi intensitas analog yang bersifat kontinu ke daerah yang memiliki intensitas diskrit.

One of the issues facing the planet is energy. Energy's significant role influences numerous local economic activities in society. To prepare for growing fuel prices, cheap, accessible alternative fuel is required. The strategy employed for this community service is socialization and training, and it is done offline (face-to-face) while still paying attention to the health program. This PkM task is broken down into multiple steps. Planning comes first, followed by gathering equipment and supplies, making briquette samples, and finally, implementing the strategy. The activity found that approximately 15 housewives participated in this PkM activity. Providing information about the energy sources needed in Indonesia and their use is part of this PkM's work program. The community service projects that have been completed are anticipated to have a beneficial impact on society and the environment, mainly on the locals of Gili Sampang Kebon Jeruk. The training participants were quite proactive during the activity, which can be proven from several questions to make alternative energy fuels good and maximum that the community can utilize. The PkM team and participants created a mutual agreement that synergizes with each other to develop alternative energy sources in the form of fuels that benefit the community.
