ESTIMASI SEBARAN CO DI TIGA PERSIMPANGAN LAMPU LALU LINTAS KOTA SURAKARTA YANG MENERAPKAN ATCS (AREA TRAFFIC CONTROL SYSTEM) DENGAN METODE MODELLING CAL3QHCR

Kota Surakarta atau yang lebih dikenal dengan Kota Solo merupakan kota transit yang biasa dilewati kendaraan dari Semarang, Yogyakarta dan Surabaya. Kondisi ini membuat jalanan Kota Surakarta padat oleh kendaraan bermotor. Kepadatan lalu-lintas yang tinggi ini berpotensi memberikan penurunan kualitas udara di perkotaan akibat dari emisi kendaraan yang ditimbulkan. Salah satu usaha pemerintah Kota Surakarta dalam menangani kepadatan lalu lintas adalah dengan menerapkan Area Traffic Control System (ATCS). Kota Surakarta telah menerapkan sistem ATCS meliputi 43 titik pantau CCTV dari 53 persimpangan yang ada.Aktivitas kendaraan bermotor yang padat di Kota Surakarta merupakan aktivitas yang menghasilkan polutan karbon monoksida (CO), sehingga dilakukan pengukuran lapangan menggunakan alat CO meter dan estimasi sebaran CO dengan metode modelling CAL3QHCR pada saat hari libur (weekend) dan hari kerja (weekday) pada jam padat kendaraan pagi dan sore hari dengan lokasi penelitian di Simpang 4 Tugu Wisnu, Simpang 3 Sriwedari dan Simpang 4 Ngapeman. Hasil konsentrasi CO pengukuran validasi di lapangan menunjukkan bahwa konsentrasi CO yang terukur masih di bawah baku mutu SK Gubernur Jateng No. 8 Tahun 2001. Konsentrasi CO hasil estimasi menggunakan CAL3QHCR dibandingkan dengan konsentrasi CO hasil pengukuran validasi di lapangan menggunakan metode Independent Sample T-Test dengan hasil terdapat perbedaan signifikan antara data konsentrasi CO hasil estimasi menggunakan CAL3QHCR dengan konsentrasi CO hasil pengukuran validasi di lapangan dengan perbedaan nilai rerata sebanyak 2,27 ppm. Hasil ini menunjukkan bahwa pengunaan software CAL3QHCR tidak efektif untuk mengestimasi sebaran konsentrasi CO di Simpang 4 Tugu Wisnu, Simpang 3 Sriwedari dan Simpang 4 Ngapeman Kota Surakarta dalam kondisi penelitian yang tidak mengukur data radiasi matahari secara langsung.

PENGARUH REGULASI DIRI AKADEMIK TERHADAP ONLINE FEAR OF MISSING OUT SISWA SMK

Online Fear of Missing Out isa huge concern about not being able to access social media. One of the causes of on-fomo is academic self-regulation. Academic self-regulation can affect on-fomo because it can help people learn how to manage social media and control it. The purpose of this study is to know the impact of academic self-regulation on on-fomo on high school students. Using a quantitative method with a simple, linear linear analysis technique (n=291). The sampling technique used is the simple random sampling technique. The scale used is the on-fomo scale and the scale of unknown-easier learning naire (aslq). Results showing academic self regulation have an impact on on-fomo resulting in negative significant value (p < 0.5; B = -115). The implications of this study are supposed to be able to make an education (preventive) for students to improve academic regulation so as to help reduce on-fomo levels, students can develop learning skills. For the next researcher, who would like to discuss on-fomo can use a variable or other approach to do in-depth research and provide a broad picture of the other variables that would contribute on-fomo to SMK students

Sintesis ZSM-5 dari Fly Ash Sawit dengan Variasi Waktu Sintesis dan Waktu Kalsinasi

Fly ash contains many elements of the high silica used as a source of silica for the synthesis of ZSM-5. ZSM-5 zeolite synthesis is one that is widely used in industry mainly as a catalyst. This is due to the ZSM-5 has a high activity and selectivity in several hydrocarbon conversion reactions. This study aimed to the synthesis of ZSM-5 of fly ash as a silica source without using templates with the time variation of the synthesis and calcination time. Synthesis performed in autoclaf at 190 ° C with a temperature variation of synthesis time 16, 18, 20 and 22 hours, calcination is done in a furnace to a temperature of 500 0 C with a variation of calcination time 4 hours, 5 hours and 6 hours. Synthesis products were analyzed by FTIR. The results showed that the best conditions for the synthesis of ZSM-5 from fly ash oil is at synthesis time of 20 hours and calcination time 4 hours. The content of ZSM-5 produced in the x-ray analysis is as much as 3%

Efficient weakly-radiative wireless energy transfer: An EIT-like approach

Inspired by a quantum interference phenomenon known in the atomic physics community as electromagnetically induced transparency (EIT), we propose an efficient weakly radiative wireless energy transfer scheme between two identical classical resonant objects, strongly coupled to an intermediate classical resonant object of substantially different properties, but with the same resonance frequency. The transfer mechanism essentially makes use of the adiabatic evolution of an instantaneous (so called “dark”) eigenstate of the coupled 3-object system. Our analysis is based on temporal coupled mode theory (CMT), and is general enough to be valid for various possible sorts of coupling, including the resonant inductive coupling on which witricity-type wireless energy transfer is based. We show that in certain parameter regimes of interest, this scheme can be more efficient, and/or less radiative than other, more conventional approaches. A concrete example of wireless energy transfer between capacitively-loaded metallic loops is illustrated at the beginning, as a motivation for the more general case. We also explore the performance of the currently proposed EIT-like scheme, in terms of improving efficiency and reducing radiation, as the relevant parameters of the system are varied.U.S. Department of EnergyDARPAArmy Research OfficeNational Science Foundatio
