MAPPING THE HOUSING AFFORDABILITY IN BEKASI CITY
Get PDFHigh urban population growth increases the housing demand and housing prices due to its limitations. These increasing urban housing prices affect housing affordability, especially for urban families with low and medium incomes. If people could buy a house with a large area in the past, now they need years to save money to buy a house with a smaller plot area. This study aims to study the level of housing affordability in Bekasi City based on current property prices. This study uses a quantitative descriptive method with three stages of analysis, namely property price analysis based on location, purchasing power analysis, and affordability analysis of house prices in Bekasi City. For buildings area up to 60m2, the price ranges from 350 to 800 million rupiahs, while the house purchasing power is less than 2.5 million per month. This research shows that most of the residents of Bekasi City cannot afford housing prices not only because of high land prices but rather its location
Prediksi Penurunan Muka Air Tanah terhadap Banjir Rob di Kawasan Pesisir Kota Jakarta
Get PDFKota Jakarta merupakan kota pesisir yang sangat rentan terhadap perubahan tinggi air laut. Selain itu, Kota Jakarta mengalami pertumbuhan yang sangat pesat sehingga kurang dapat memenuhi kebutuhan dasar penduduknya, termasuk infrastruktur air bersih, sehingga penduduk Kota Jakarta menggunakan air tanah dalam memenuhi kebutuhan air bersihnya.

Design of Horizontal Axis Wind Turbine Simulator Using Smart Monitoring System
Get PDFWind turbine shows the direct utilization of mechanical energy and occurs as follows: the wind that moves hitting the wing of the ferris wheel causes the ferris wheel to spin. The rotation of the ferris wheel causes the formation of mechanical energy, while the conversion of wind energy into electrical energy is as follows: the wind through the ferris wheel plants causes the ferris wheel to spin. The spin of the ferris wheel causes the generator to spin. Inside the wind energy generator is converted into electrical energy. In the Final Task that did the design of this prototype, do a comparison between the horizontal axis wind turbine with variations in the number of blades, with blade variations totaling 3 and 5. So, there will be 2 wind turbines with different numbers of blades in one prototype. Comparisons are made to find out the performance carried out by the two wind turbines that aim as a learning medium in the Measurement Instrumentation Laboratory. This final task is divided into five stages: including, tool design, tool characterization, tool validation, tool testing, and comparing tools. The process of designing tools that are divided into two methods, namely covering the formation of hardware and the formation of software. From the graph data contained in the discussion shows the performance with the propeller amounting to 5 produces a higher current and voltage output and rpm on this prototype scale than the number of propellers 3, with the value for example at the acceleration of fan 5 with a wind speed of 3.9 m / s on the propeller amounting to 5 resulting in an average current value of 3.2 mA, a voltage of 1.98 V, and rotor rotation of 234 RPM. While at the number of propellers 3 with the same wind speed produces smaller current output, voltage and rpm, which is obtained an average current of 2.3 mA, a voltage of 1.88 V, and rotor rotation of 243 RPM

Using Thinking Routines To Improve The Reading And Writing Skills Of Elementary Students
Get PDFDeveloping thinking skills in teaching and learning, including English lessons, is prominent. Reading and writing are the ability that requires synthesis and higherorder thinking skills. Thinking routines as part of thinking culture is one strategy to develop thinking skills. This study investigated the importance of thinking routines in improving sixth-grade elementary school students reading and writing skills. The quasi-experimental research was conducted with 64 students divided into a control group (N=32) and an experimental group (N=32). The topic of reading and writing was appropriate for the sixth-grade students’ developmental stage. Reading and writing tests were used as data collection tools. The experts validated the reading topic and the tests. The data is analyzed statistically using the Mann-Whitney U Test. The results reveal two significant findings. The first finding was that thinking routines did not significantly improve sixth-grade students’ reading skills. On the other hand, thinking routines improved writing skills significantly. The evidence from this study suggests using thinking routines in English teaching as a base to support and structure students thinking with various perspectives. In addition, thinking routines also support students in writing opinions based on the information given
Men With Hijab: Menetapkan Kejamakan Identitas Gender Cross-Hjaber di Media Sosial
Get PDFRejection of cross-hijaber is typical of societies with traditional gender ideologies in Indonesia. In Indonesia, cross-hijaber is stigmatized with criminal, psychiatric, and sexual disorders, as well as identity crises. This study examines how cross-hijaber displays his identity in the public and private spheres via social media, both communally and individually. Cross-hijaber social identity and cross-hijaber personal identity are examined in greater detail in this study. Using a virtual ethnographic method, the study examined cross-hijaber on a Facebook group. The results of the study reveal the diversity and complexity of cross-hijaber identities in social media interactions. The distinction between social and personal identities is no longer distinct because the two can exchange positions depending on context. When cross-hijabers begin to wear their hijab, their cisgender identities will be concealed. Even cross-hijaber identity is fluid based on the social context. Otherwise, when they become cisgender, the cross-hijaber identity will not be displayed
