Socioeconomic Status, Academic Success, and Relationship with Parent/Guardian: Contributions to Marijuana Use in Teens

As illicit drug use has steadily increased over the last decade, marijuana use has become much more prevalent among a variety of age groups. According to the 2014 National Survey on Drug Use and Health, 8.6 million adolescents and young adults (age 12-25) use marijuana. This is significant as prior studies have found that marijuana use has damaging effects on the brain, especially teens whose brains are still developing. In order to gain a better understanding as to why individuals engage in marijuana use and how it may act as a coping mechanism, this study looks at how sources of strain (socioeconomic status, academic success, and relationship with parent/guardian) affect individuals (age 16-20) chances of using marijuana. This study uses logistic regression as the method for analyzing data from the National Longitudinal Study of Youth-1997 and draws from Robert Agnew’s general strain theory. The study finds that greater academic success predicts a decrease in marijuana use, a better relationship with a parent/guardian predicts a decrease in marijuana use, and males are much more likely (37-59%) to use marijuana than females. Although socioeconomic status was significant in predicting marijuana use, the coefficient is so small in magnitude that it is not clear if SES matters. This study gives us a better understanding of the impact of strain caused by academic success, and how teens use marijuana as a coping mechanism to strain. Future research should be done to further explore the impact that strain has on teen lives and how marijuana acts as a coping mechanism. In addition, research on the impacts of other sources of strain can further our understanding of why teenagers engage in drug use

Mini-Review Mengenai Pemanfaatan Material Berbasis Polimer Koordinasi Berpori untuk Penyimpanan Hidrogen

This review aims to summarize the various types of Metal-Organic Frameworks (MOFs) and their utilization for hydrogen storage. MOFs have high surface area, flexibility, good stability and tunability, various active sites, and abundant raw materials. These characteristics make MOFs worthy of being considered as a new material in hydrogen storage applications. The potential for using MOFs is very broad because its properties can be determined from the choice of metal and linker. Hydrogen gas storage commonly requires high pressure tanks whereas in liquid form, it requires cryogenic temperatures due to its very low boiling point, the challenge is to synthesize MOF with high hydrogen adsorption capacity under mild conditions. Moreover, it is crucial to learn about the relationship among the pore volume and surface area of MOFs, physisorption of hydrogen, and adsorption condition

Kebijakan Perencanaan Pembangunan: Sebuah Kajian Pustaka Terstruktur (Systematic Literatur Review)

Penelitian ini memiliki tujuan untuk melihat sebuah proses kebijakan dalam perencanaan pembangunan di terapkan. Didasari oleh sebuah kebijakan pemerintah yang memiliki peran penting dalam sebuah pemberian kebijakan dalam rangkaian konsep dan asas yang menjadi pedoman dan dasar rencana dalam pelaksanaan suatu pekerjaan. Kebijakan dipahami sebagai arah atau pola kegiatan dan bukan sekedar suatu keputusan untuk melakukan perencanaan pembangunan. Penelitian ini menggunakan metode literatur dengan menggunakan pendekatan studi literatur dengan mengkaji dari beberapa artikel jurnal internasional yang diakses dari Scopus, dengan kata lain penelitian ini menggunakan bahan-bahan pustaka tanpa melakukan riset lapang. Penelitian ini mengungkapkan bahwa keberlangsungan dari sebuah pembangunan tentu didasari oleh sebuah kebijakan dan perencanaan. Dimana kedua aspek tersebut harus dirumuskan secara terstruktur dan sesuai dengan tujuan. Kebijakan perencanaan pembangunan tentu memerlukan sebuah proses yang harus didasri dari kebutuhan suatu daerah atau negara. Kebijakan perencanaan tersebut perlu dilakukan dengan melihat beberapa aspek penting seperti penggunaan lahan, urbanisasi, dukungan negara dan masyarakat, zona pembangunan, mitigasi perubahan iklim dan kerjasama. Tentu dalam hal ini kebijakan regulasi perlu dilakukan melalui berbagai pendekatan yang logis. Dalam proses tersebut pemerintah perlu melibatkan stakeholder dan masyarakat dengan mengkaji apa saja hal yang dibutuhkan dalam proses perencanaan pembangunan sehingga melahirkan kebijakan atau regulasi yang baik dan saling menguntungkan. Temuan menunjukkan pentingnya kerjasama dan partisipasi luas dari berbagai pemangku kepentingan, pengelolaan budaya yang baik. Keterbatasan tulisan ini adalah kurangnya data yang dikaji secara nasional dikarenakan tulisan ini dikaji dari artikel yang berbasis internasional, namun disis lain tulisan ini dapat dikatakan sesuai dengan dasar dari kebijakan perencanaan pembangunan. Dengan begitu, karya tulis berikutnya perlu dilakukan dengan membandingkan terhadap penerapan kebijakan perencanaan pembangunan yang lebih terkonsep

MECCA MEAN TIME PROBLEMATIC AS A WORLD TIME REFERENCE

Desire of Muslims to replace the present standard of time, namely Greenwich Mean Time, to Mecca Mean Time is the manifestation of a new spirit in the Islamic world in particular. Mecca Mean Time makes al-Abraj tower (Mecca Royal Clock) the zero degree point or standard for the commencement of global time. The goal of this study is to find out what are the challenges that occur when Mecca Mean Time is used as a reference for global time. This research is a sort of qualitative research involving library research studies by describing descriptively. After the data is obtained, the author will categorize, analyze and present it in the form of a brief and systematic document. In this study, it was revealed that there was a debate of variations in views amongst different specialists when MMT was utilized as a reference for global time. Bambang Eko Budhiyono is striving very hard to achieve MMT as a world time reference on the basis of interpretation of the Qur'an verse 1 al-Hujurat. Meanwhile, Thomas Djamaluddin has a different perspective since physically and geographically there are no qualities that assist it to make it a time reference or as a main meridian (Prime Meridian) except religious spirit
