Judul: Kasus: Mahasiswa Perguruan Tinggi Negeri Di Kabupaten Bogor, Jawa Barat
Abstrak: Now day, internet game industry or as we know as game online has growth faster of its. It can connect one people in one area to each other without distance limit. Online games put gamer to prefer communicate virtually than direct communication. The research objectives are to observe gamer’s characteristics and behavior. The observational data acquired from 30 respondents of IPB students, with snowball sampling and purposive sampling. The results of this research are; gamers majority were male gamers, gamers generally plays at game center, gamers had average GPA of 2.51 to 2.75 or above, and play game online for about 22 hours to more than 48 hours in one week. The gamer’s behavior was seen from the pattern of playing games, the pattern of taking care of theirselves and the pattern of the social interaction that tended low when they began to experience addiction, the pattern of the behavior that tended to neglect. Based on the characteristics and the behavior of gamers there’s four typologies that were stratified from non-addicted to high-level addicted. The indicators of addiction based on previous researches began to emerge when gamers was in the type of advanced gamers and hyper gamers or could be said for them that played game online more than 34 hours in one week.

Judul: The Effect of Self Esteem, Academic Efficacy, Academic Motivation on the Game Online Addiction in Undergraduate Students During the Covid-19 Pandemic
Abstrak: Pandemi Covid-19 berdampak kepada berbagai segi kehidupan manusia di berbagai belahan dunia, termasuk mahasiswa Berbagai hasil penelitian menunjukkan terjadinya peningkatan konsumsi hiburan digital, khususnya game online pada mahasiwa di masa pandemi Covid-19. Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik individu, karakteristik keluarga, harga diri, efikasi akademik, dan motivasi akademik terhadap kecanduan game online mahasiswa. Penelitian ini menggunakan desain eksplanatori dengan partisipan sebanyak 220 mahasiswa yang pernah atau sering bermain game online. Penelitian berlokasi di salah satu perguruan tinggi di Jawa Barat dan pengambilan contoh dilakukan secara purposive. Data diperoleh melalui self-report dengan menggunakan kuesioner, yang selanjutnya diolah dengan analisis deskriptif, uji korelasi, dan uji regresi linier berganda. Hasil penelitian menunjukkan gender dan efikasi akademik berpengaruh negatif terhadap kecanduan game online sedangkan usia mahasiswa dan tingkat pendidikan ibu berpengaruh signifikan positif terhadap kecanduan game online pada mahasiswa. Usia ayah, pendidikan ayah, usia ibu, besar keluarga, pendapatan per kapita, harga diri, dan motivasi akademik tidak terdapat pengaruh signifikan terhadap kecanduan game online., The Covid-19 pandemic has an impact on various aspects of human life in various parts of the world, including students various research results show an increase in the consumption of digital entertainment, especially online games. This study aims to analyze the effect of individual characteristics, family characteristics, self-esteem, academic efficacy, and academic motivation on the intensity of playing online student games. The design in this study is quantitative. The respondents in this study were 220 undergraduate students who had or often played online games. The research was located in a tertiary institution in West Java and the sampling was done purposively. Data obtained through self-report using online questionnaires, then processed with descriptive analysis, correlation tests, and multiple linear regression tests. The results showed that students self-esteem in the medium category, low academic efficacy, moderate academic motivation, and the game online addiction was very high. There was a significant relationship between self-esteem and academic efficacy with the game online addiction. Gender, student age, mother's education duration, and academic efficacy had a significant positive effect on game online addiction for undergraduate games. Father's age, father's education, mother's age, family size, per capita income, self-esteem, and academic motivation did not have a significant effect on online game addiction.

Judul: Penentuan Kondisi Proses Pemisahan Sitronelal dan Rhodinol dari Minyak Sereh Wangi dengan Distilasi Fraksinasi Vakum
Abstrak: Minyak sereh wangi merupakan salah satu minyak atsiri yang memiliki komponen utama sitronelal dan rhodinol. Komponen utama tersebut dapat dipisahkan dengan metode distilasi fraksinasi. Proses distilasi fraksinasi dengan alat dan kondisi proses berbeda berpengaruh terhadap proses pemisahan fraksi minyak sereh wangi. Oleh karena itu, perlu diketahui pengaruh suhu dan rasio refluks pada proses pemisahan sitronelal dan rhodinol minyak sereh wangi dari unit distilasi fraksinasi vakum kapasitas 7L yang telah di desain dengan spesifikasi tertentu. Proses pemisahan dilakukan pada tekanan 60 mmHg dengan umpan 5L dan dilanjutkan proses redistilasi fraksi kaya sitronelal dan rhodinol. Fraksi sitronelal dan rhodinol yang dihasilkan dilakukan analisis GC-MS untuk mengetahui konsentrasi masing-masing fraksi. Variasi refluks yang digunakan pada pemisahan sitronelal yaitu 12:4, 6:4, 6:2 dan 10:10. Suhu dan rasio refluks berpengaruh terhadap kemurnian fraksi. Kemurnian fraksi sitronelal tertinggi yang dihasilkan yaitu sebesar 50,55% dan fraksi rhodinol sebesar 37,09% pada rasio refluks 6:4. Proses redistilasi fraksi kaya sitronelal dan rhodinol menghasilkan konsentrasi senyawa sitronelal sebesar 42,72% dan senyawa rhodinol sebesar 32,51% dengan rasio refluks 10:10. Kemurnian sitronelal meningkat dan waktu proses lebih singkat dikarenakan pada suhu dan rasio refluks yang digunakan, alat bekerja lebih baik sehingga menghasilkan kemurnian lebih tinggi. Kata kunci: distilasi fraksinasi vakum, minyak sereh wangi, refluks, rhodinol, sitronelal, Citronella oil is one of the essential oils that has the main components of citronellal and rhodinol. The main components can be separated by fractional distillation method. Fractional distillation process with different tools and process conditions affect the separation process of citronella oil fraction. Therefore, it is necessary to know the effect of temperature and reflux ratio on the separation process of citronellal and rhodinol of citronella oil from a 7L capacity vacuum fractionation distillation unit which has been designed with certain specifications. The separation process was carried out at a pressure of 60 mmHg with 5L feed and continued with the redistillation process of the citronellal and rhodinol-rich fractions. The resulting citronellal and rhodinol fractions were analyzed by GC-MS to determine the concentration of each fraction. Reflux variations used in citronellal separation are 12:4, 6:4, 6:2 and 10:10. Temperature and reflux ratio affect the purity of the fraction. The highest purity of the citronellal fraction produced was 50.55% and the rhodinol fraction was 37.09% at a reflux ratio of 6:4. The redistillation process of citronellal and rhodinol-rich fractions resulted in a concentration of citronellal compounds of 42.72% and rhodinol compounds of 32.51% with a reflux ratio of 10:10. The purity of citronellal is increased and the processing time is shorter because at the temperature and reflux ratio used, the tool works better resulting in higher purity.
