Higher education is present as a forum that has a considerable contribution in improving the quality of human resources in a nation according to the Law of the Republic of Indonesia Number 12 of 2012 concerning Higher Education point c reads; that in order to increase the nation's competitiveness in facing globalization in all fields, higher education is needed that is able to develop science and technology and produce intellectuals, scientists, and/or professionals who are cultured and creative, tolerant, democratic, have strong character, and dare to defend the truth for the interests of the nation. Universities as organizations that aim at service satisfaction are currently no longer reliable in terms of competitive advantage in this era of very high competition because other universities are also doing the same thing, so organizations need to emphasize commitment to achieving organizational goals by proactively improving the organization's image and increase student loyalty by looking at the quality of service and the quality of human resources (HR). The research method used is a quantitative approach with a total of 369 respondents with data analysis used through the SmartPLS 3.0 program, while the results obtained in this study are (1) Service Quality on Student Satisfaction has a direct but not significant effect; (2) Service Quality has a direct and significant effect on Organizational Commitment; (3) Quality of Human Resources has a direct but not significant effect on Organizational Commitment; (4) the quality of human resources has a direct and significant effect on student satisfaction; (5) Organizational Commitment has a direct and significant effect on Student Satisfaction; while (6) the quality of service has not been able to directly increase student satisfaction, and Organizational Commitment as a very important mediation needed to be able to increase the influence of Service Quality on student satisfaction; and (7) the quality of human resources can directly increase student satisfaction even without going through organizational commitment, so that the existence of organizational commitment as a mediation is not needed to be able to increase the influence of service quality on student satisfaction

The COVID-19 pandemic was causing unexpected challenges for all education systems. Several online platforms launched by the ministry of education maximize available e-learning solutions such as virtual education resources and open classrooms, encourage the possibility of innovation and accelerated digital transformation initiatives, and further develop lecturers' digital skills and competencies. This study aims to analyze the comparative needs of the current digital environment of Indonesian higher education and conduct an in-depth study of digital learning in the Indonesian higher education environment. This study also outlines the mitigation plan, the innovative strategy adopted, and the implications and recommendations for Indonesian universities. The research method uses a discourse analysis with literature and news sources to assess the higher impact, challenges, and opportunities of education during the pandemic in Indonesia. This study finds that the COVID-19 pandemic has had a significant impact on higher education in Indonesia; Both lecturers and students in universities face many challenges in the teaching and learning process. The effect is worse in Eastern Indonesia due to poor internet connectivity for online learning. In terms of mitigating online learning, the impact is still unknown. The limitation in this study states that the literature and news studies are not comprehensive because the current pandemic crisis has not ended. This study can represent an illustration of the limitations of a more empirical study to be conducted on how the current crisis affects the learning process of Indonesian universities.

Telah dilakukan penelitian berupa modifikasi material fotokatalis berbasis titanium dioksida (TiO2) pada material penyangga polipropilena (PP). Material fotokatalis adalah jenis material yang digunakan dalam beberapa proses degradasi senyawa organik dengan bantuan aktivasi oleh foton. Modifikasi dilakukan menggunakan teknik thermal milling. Teknik ini memanfaatkan Heat Deflecting Temperature untuk menempelkan TiO2 pada permukaan PP. Temperatur yang digunakan adalah 175 °C dan dilakukan selama 40 menit. Perbandingan PP dan TiO2 yang digunakan sebanyak 4:1 dengan massa masing-masing 140 g dan 35 g. Hasil penelitian ini dapat dilihat dari tiga hal yakni visual material hasil sintesis, perubahan massa, serta hasil visual proses fotodegradasi menggunakan material hasil sintesis. Visual material hasil sintesis menunjukkan permukaan yang kasap serta terjadi pertambahan massa sebesar 1,4 g untuk tiap 47 g. Hal ini menunjukkan bahwa PP telah berlapis TiO2 sehingga dapat dikatakan PP mampu menjadi material penyangga TiO2 sebagai material fotokatalis. Untuk proses fotodegradasi, terjadi perubahan warna pada limbah artifisial. Perubahan yang terjadi adalah limbah berangsur-angsur memudar. Hal ini menunjukkan performa material hasil sintesis mampu melakukan proses fotodegradasi. Pada proses ini juga tidak ditemukan adanya residu tambahan sehingga penelitian ini menunjukkan keberhasilan PP dalam solusi untuk menciptakan metode degradasi tanpa residu tambahan.

Dinamika hidrat metana tipe MH-IV pada berbagai kondisi termodinamika telah diteliti menggunakan metode dinamika molekul. Hidrat metana dikondisikan pada suhu 250 K dan tekanan 40 GPa, 70 GPa, 100 GPa, 140 GPa dan 150 GPa. Berdasarkan hasil perhitungan energi sistem, sistem hidrat yang disimulasi belum sepenuhnya mendekati hasil eksperimen yang ingin direplika. Fungsi distribusi radial dari sistem yang disimulasi menunjukkan pengaruh signifikan tekanan terhadap jarak koordinasi antar molekul penyusun hidrat. Sistem terlihat mengalami deformasi seiring dengan pertambahan tekanan. Beberapa bagian dari sistem terlihat mengalami deformasi yang diikuti dengan pemutusan ikatan hidrogen antar molekul air. Hal tersebut mengakibatkan sistem tidak lagi memiliki struktur kristal es seperti kondisi awal. Perubahan struktur yang dialami menyebabkan probabilitas molekul metana untuk berdifusi ke void baru menjadi semakin besar. Peningkatan tekanan yang diaplikasikan pada sistem menyebabkan kerusakan struktur semakin meluas yang diikuti dengan meningkatnya koefisien difusi molekul gas metana.Kata Kunci : Hidrat Metana MH-IV, Dinamika Molekul

Many images are spread in the virtual world of social media. With the many editing software that allows so there is no doubt that many forgery images. By forensic the image using Error Level Analysis to find out the compression ratio between the original image and the fake image, because the original image compression and fake images are different. In addition to knowing whether the image is genuine or fake can analyze the metadata of the image, but the possibility of metadata can be changed. In this case the authors apply Deep Learning to recognize images of manipulations through the dataset of a fake image and original images via Error Level Analysis on each image and supporting parameters for error rate analysis. The result of our experiment is that we get the best accuracy of training 92.2% and 88.46% validation by going through 100 epoch.
