Abstract

It has successfully conducted research to study the structure of the icosahedral formation in the event of change of the solid phase - liquid-solid using molecular dynamics method . The result showed that the percentage of the maximum icosahedral structure is obtained when the simulation is run at the start of the cooling temperature of 2875 K at a rate of temperature decrease of 0.064 K /step and at the beginning of the cooling temperature of 3000 K at a rate of temperature decrease 0.12 K/step. While icosahedral minimum percentage obtained when the simulation is run at a temperature of 2750 K with the initial cooling rate of temperature decrease of 0.069 K/step. Based on these results we can conclude that there is a relationship between the initial temperature of the cooling and the rate of temperature decrease of the icosahedral structure is formed. Keywords: Icosahedral, phase change, molecular dynamics

Abstract

The Physics Education study program, Nusa Cendana University, already has a web-based study program information system but it has not been managed optimally, as evidenced by the limited availability of study program data on the web. This study aims to identify the data needed to be developed into useful information, not only for the academic community of the Physics Education undergraduate study program, Nusa Cendana University, but for society in general. The method used is to carry out an issue analysis based on APKL and USG techniques. The results of the identification of issues were then consulted with stakeholders, in this case the dean of the Teaching and Education Faculty, and the coordinator of the Physics Education Study Program. The data obtained is then made into a graphic design or linked to a menu available on the web, so that it becomes useful information.

Abstract

Simulations have been carried out to study the recrystallization of iron materials after heat treatment. The heat treatment carried out consists of heating the iron from room tempera-ture to critical temperature with different heating temperatures and cooling to room tem-perature with different cooling times. This study was carried out to obtain information on the occurrence of material recrystallization after the heat treatment process was carried out. This simulation approach was carried out using molecular dynamics methods and utilizing LAMMPS software. The heat treatment process begins by heating the iron from room temperature (300 K) until it reaches a critical temperature, even past the critical temperature value. Then a cooling process is carried out to observe the material recrystallization process. Through these two stages of heat treatment, analysis is carried out to observe the material structure at the end of the simulation. Based on the simulations that have been carried out, the results show that the ma-terial’s recrystallization is more influenced by the cooling time than the initial cooling tem-perature. More than 60% of the BCC structures formed at the end of the simulation for all initial cooling temperatures, but for very short cooling times 16% of the BCC.

Abstract

Pengabdian kepada masyarakat (PKM) ini adalah agar siswa Kelas XII SMAK Lamaholot Witihama ini adalah kegiatan pelatihan memahami soal tes untuk mengikuti tes SNBT untuk melajutkan ke universitas negeri penyelenggara tes UTBK-SNBT. Metode PKM diselenggarakan dengan metode pelatihan, diskusi, ceramah, tanya jawab, dan latihan soal dan tes. Hasil yang diperoleh dari kegiatan PKM ini adalah dari antusias siswa SMA yang hadir dalam bentuk semangat bertanya, dengan demikian siswa memahami dan pentingnya berjuang untuk lulus ujian sekolah dan mendapatkan gambaran terkait jenis-jenis soal dan strategi untuk bisa menyelesaikan soal Tes Potensi Skolastik (TPS), literasi dalam Bahasa Indonesia dan Bahasa Inggris, serta Penalaran Matematika dengan baik hingga lulus tes dan dapat melanjutkan ke jenjang pendidikan pada tingkat universitas yang diinginkan. Hipotesis yang diajukan adalah ada perbedaan hasil tes antara siswa yang awal sebelum diberikan pelatihan (pretest) dan sesudah mengikuti pelatihan (posttest). Hasil analisis Paired Sample Test pada tabel menunjukkan bahwa nilai t yang dihasilkan adalah 9,246 dengan signifikansi 0,000. Karena nilai signifikansi lebih kecil dari taraf signifikansi yang ditetapkan (0,05), hipotesis nol (H0) dapat ditolak. Dengan kata lain, terdapat perbedaan yang signifikan antara nilai pretest dan posttest.

Abstract

Penelitian ini telah dilakukan untuk mengetahui sifat elektronik grafit berdasarkan kurva band structure dan density of states menggunakan metode density functional theory yang diimplementasikan dengan perangkat lunak Quantum Espresso. Sebelum melakukan perhitungan dilakukan studi konvergensi energy cut-off dan k-point. Perhitungan dilakukan dengan energy cut-off 125 Ry dan k-point 30 30 30. Dari kurva band structure, maka sifat elektronik grafit adalah semikonduktor dengan energi band gap 0,01085552 eV. Sedangkan, berdasarkan kurva density of states, maka diperoleh density of states yang tinggi pada 2 eV di dekat tingkat Fermi. Kurva density of states dengan spin-up dan spin-down menunjukkan bahwa grafit merupakan material non-magnetik.

Abstract

Foti bobouk dance is a typical dance that is always performed in every event among the Rote tribe. However, the attractive and lively movements of the foti bobouk dance actually carry the risk of musculoskeletal disorders (MSDs) for dancers. This study aimed to analyze the relationship between body posture, age and body mass index with MSDs of foti bobouk dancers. The design of this study was cross-sectional, involving 30 dancers from the Rote tribe who live in Kupang city. The dancers were selected using a purposive sampling technique. The variable measurement instrument was the Rapid Entire Body Assessment (REBA) to assess the level of MSDs risk in dancers due to body posture while dancing and the Nordic Map Questionnaire (NMQ) to identify subjective complaints of MSDs felt after performing the foti bobouk dance movements. Age was measured by filling out a questionnaire and body mass index was measured by measuring body weight and height directly. The collected data were analyzed using the Spearman correlation test. The results showed that the p value for each independent variable was 0.038 for body posture, 0.021 for age and 0.822 for body mass index. It was concluded that age and body posture were determinants of subjective complaints of MSDs of foti bobouk dancers in Kupang City.Keywords: foti bobouk dance; musculoskeletal disorders; body posture; age ABSTRAK Tari foti bobouk merupakan tarian khas yang selalu ditampilkan dalam setiap acara di kalangan masyarakat suku Rote. Meskipun demikian gerak tari foti bobouk yang atraktif dan bersemangat ternyata menyimpan resiko timbulnya keluhan musculoskeletal disorders (MSDs) bagi penari. Penelitian ini bertujuan untuk menganalisis hubungan antara postur tubuh, usia dan indeks massa tubuh dengan MSDs penari foti bobouk. Rancangan penelitian ini adalah cross-sectional, yang melibatkan 30 penari dari suku Rote yang berdomisili di kota Kupang. Para penari tersebut dipilih dengan teknik purposive sampling. Instrumen pengukuran variabel adalah Rapid Entire Body Assessment (REBA) untuk menilai tingkat resiko MSDs pada penari akibat postur tubuh saat menari dan Nordic Map Questionnaire (NMQ) untuk mengidentifikasi keluhan subyektif MSDs yang dirasakan setelah melakukan gerak tari foti bobouk. Usia diukur melalui pengisian kuesioner dan indeks massa tubuh diukur melalui pengukuran berat badan dan tinggi badan secara langsung. Data yang telah terkumpul dianalisis menggunakan uji korelasi Spearman. Hasil penelitian menunjukkan bahwa nilai p untuk masing-masing variabel bebas adalah 0,038 untuk postur tubuh, 0,021 untuk usia dan 0,822 untuk indeks massa tubuh. Disimpulkan bahwa usia dan postur tubuh merupakan determinan keluhan subyektif MSDs penari foti bobouk di Kota Kupang.Kata kunci: tari foti bobouk; musculoskeletal disorders; postur tubuh; usia
