Abstract

Rangka Terbreis Eksentris (RTE) merupakan sistem bangunan tahan gempa yang mempunyai keunggulan dari segi kekuatan dan kekakuan serta mempunyai daktilitas dan kemampuan energi disipasi yang baik dalam kondisi inelastis. Link adalah elemen penting yang berfungsi untuk mendisipasikan energi gempa melalui perilaku inelastis struktur. Kinerja link geser berupa kekuatan, kekakuan, daktilitas dan disipasi energi tergantung pada profil penampang yang digunakan pada link. Kajian ini bertujuan untuk mengetahui perilaku struktur RTE dengan link menggunakan sambungan baut yang menggunakan variasi mutu baja serta pelebaran ujung pelat sayap (Side Extended Plate/SEP) dan tanpa SEP. Analisis dilakukan dengan menggunakan menggunakan software MSC PATRAN/NASTRAN. Sebanyak 8 (delapan) variasi model link dikaji untuk menentukan kinerja struktur yang paling optimum ketika dilakukan pembebanan statik monotonik dan siklik dengan kontrol perpindahan. Hasil menunjukkan bahwa variasi mutu baja link pada pelat sayap dan pelat badan dapat meningkatkan kekuatan, kekakuan, dan daktilitas struktur secara signifikan dibandingkan dengan penggunaan SEP. Kata kunci : Rangka Terbreis Eksentis (RTE), link geser, link sambungan baut dan las, variasi mutu baja, pelebaran pelat sayap

Abstract

Conventional drug delivery systems have a shorter residence time in the stomach that causes less optimal drug absorption, the presence of food in the stomach also affects the absorption of the drug in the gastrointestinal tract so that it takes a drug that can stay and last longer in the stomach without being affected by the emptying process Stomach. In this study beads preparations are made that can stay and float so that lasts longer in the stomach. Alginate-containing beads are formulated by gelation method in which the alginate solution is dropped into a calcium chloride solution to form beads. The effects of oil type and alginate on morphological forms and buoyancy characteristics have been optimized. Beads containing alginate and paraffin can float on a gastric medium simulation for 240 minutes. The presence of paraffins can maintain the integrity and release of alginate beads during contact with the gastric medium. The SEM results describe the paraffin forming globules on the entire surface of the beads. Beads also show the ability to be able to float depending on the concentration of paraffin used.

Abstract

In the developing country or poor country difficult to access meteorological data such as air temperature, it's caused by the limitation of equipment or funding. Air temperature is one of the meteorological data commonly used to predict evaporation or to understanding climatic condition in a specific location. Nowadays from satellite data can estimate some meteorological data. But the detail of explanations about how to get and how to use satellite data is limited and difficult to adopt for beginners. This paper explains how to get MODIS LST data to estimate air temperature data study case in Gifu City, Japan. The results show data from MODIS LST is higher than data from the local meteorological station for day time and lower for night time, but still can use because the pattern is similar. Mean of maximum air temperature and minimum air temperature can be used as daily average air temperature. MOD11A2 product data was better than MYD11A2 data to predict air temperature. MODIS LST data can be used for untouched areas like desert or forest.

Abstract

Special Interest Tourism is an alternative for experiency tourist attraction based on particular motivation and interest of the travelers different from attractions. The problem that has been persisty is that the local community of Gamaran Salibutan Village cutting trees and damaging nature in Gamaran Protected Forest which carry out potential and natural tourist attractions. This study analyze the change of society’s economic behaviour as an effect of rural nature tourism development. The method used Qualitative research with case study approach. The analysis showed that the presence of tourism development of Nyarai Waterfall has positive benefits for the economy of the local community, namely the increase of people's income and their job opportunities as a tour guide for woodcutter the unemployed youth and the women are able to open a stall so that possibly in adding to the family income.

Abstract

Finite Diffrence Time Domain merupakan metode simulasi yang digunakan dalam simulasi gelombang elektromagnetik dimana mengunakan prinsip dasar pendekatan numerik dari persamaan differensial dalam domain ruang dan waktu. Phased array antenna merupakan salah satu jenis antenna yang dapat diaplikasikan pada automotive radar. Phased array antenna yang disimulasikan terdiri dari microstrip antenna dengan jumlah 64 antenna ( 8 baris, 8 kolom). Microstrip antenna terdiri dari 3 bagian yaitu patch, substrate dan ground. Ukuran patch pada microstrip antenna adalah 1.2 x 2.6 mm. Permitivitas relatif substrate yang digunakan adalah 10.2. Hasil yang diperoleh dari simulasi ini adalah pola radiasi dari phased array antenna berbentuk directional.
