PERILAKU BERKENDARA SEPEDA MOTOR 150 CC MENGGUNAKAN METODE NATURALISTIC DRIVING STUDY DAN DRIVERS BEHAVIOUR QUESTIONNAIRE
Driver behavior is the most dominant factor in accidents. Almost all accidents are preceded by violations of traffic signs. Through previous accident data, important and useful information can be known. The study aims to analyze two-wheeled motorbike riding behavior using Naturalistic Driving Study (NDS) and determine the influence of age and behavior of 150cc motorbike riders. Data taken from recordings taken by respondents and questionnaires. The results of the regression test to determine differences in age on motorbike rider behavior with a constant value of a = 196.03 show that this figure is a constant number which means that, if it does not involve age (X), the value of riding behavior (Y) is -5, 3956x. The regression coefficient is -5.3945. This figure is minus (-), which means that age (X) has a negative effect on driving behavior (Y)
PEMANFAATAN BAHAN LOKAL BAMBU MAYAN SEBAGAI BAHAN SUBSTITUSI ANGREGAT PADA BETON
Bamboo is a plant that can be found around us, especially in rural areas. Bamboo is an environmentally friendly building material compared to conventional building materials. In addition to being easily accessible, cheap, and lightweight, bamboo also possesses considerable strength. There have been numerous studies on the use of bamboo, but in this research, bamboo is utilized as a substitute material for coarse aggregates. The planned compressive strength is for concrete with a compressive strength of K250 (20.75MPa) with substitution proportions of 30%, 50%, and 100%, which will be compared with normal concrete. In this study, it is expected to determine the proportion of substitution of coarse aggregates in concrete using bamboo. Based on the tests conducted, ranging from testing concrete-forming materials to compressive strength tests, the compressive strength obtained for normal concrete (0%) at 28 days is 26 MPa. Meanwhile, the compressive strength for concrete with a 30% substitution proportion is 26 MPa, 50% proportion is 13 MPa, and 100% proportion is 9 MPa. Thus, it can be concluded that the greater the percentage of concrete substitution, the lower the compressive strength obtained

Abstract: Frequency Control System Modeling at PLTMH PTPN Kayu Aro . In this PLTMH system, problems often occur, especially distribution instability caused by changes in load. This causes the frequency in the generating system to be unstable which can result in damaged electrical equipment. Therefore, in this study, optimizing the frequency control by using PID control to adjust the Load Frequency Control (FLC). To obtain optimal PID control parameters, the Ziegler- Nichols method was used. The micro hydro power system in this study uses an induction generator, a servo operated as a governor and several other components. This generator is modeled in a simulation using the matlab-simulink program.

Abstract: Decision-Making System for Recipients of Direct Cash Aid (BLT) Using the Website-Based Simple Additive Weighting (SAW) Method. Direct Cash Aid – Bantuan Langsung Tunai (BLT) is a conditional assistance program from the government as a form of compensation for rising fuel oil prices – Bahan Bakar Minyak (BBM). At the selection stage of prospective recipients (BLT) it was not fully on target because it was still done manually so that many were not on target. Based on this, research was carried out to design a decision support system that would make it easier to check data on prospective residents who are entitled to receive BLT funds automatically for each distribution. So that the selection process can be more objective, time efficient and can minimize selection errors that may arise in the selection of prospective BLT recipients. In this study, the Simple Additive Weighting (SAW) method was used. The sampling data used is data from the head of the inhabitant in Satria Jaya Village, Tambun Utara District, Bekasi. The calculation process uses the SAW algorithm and the system implementation in the form of a Website with the waterfall method gives good and accurate results. The analysis given is based on the results of multiplication and addition of normalized matrices with predetermined weight values. Determination of the final value range of 0 – 0.75 as the value used to determine the eligibility of prospective BLT recipients based on field observations in the village. The simulation results for calculating data on prospective BLT recipients using the SAW algorithm yielded 25% of the simulated results of the tested data being residents who passed as BLT aid recipients.

PENGARUH CAMPURAN SERBUK STYROFOAM DAN ABU KAYU TERHADAP NILAI CBR TANAH DASAR
Pengaruh Campuran Serbuk Styrofoam dan Abu Kayu Terhadap Nilai CBR Tanah Dasar. Tanah dasar berperan vital pada konstruksi jalan termasuk jalan di Tepus-Jerukwudel II. Di sisi lain, tanah dasar yang merupakan tanah lempung termasuk salah satu tanah yang mempunyai banyak kekurangan, diantaranya mempunyai sifat kohesi tinggi, daya dukung rendah, ataupun nilai CBR yang relatif rendah, dikarenakan kondisi tersebut perlu diadakan stabilisasi pada tanah lempung untuk memperbaiki sifat tanah tersebut, apabila tidak diperbaiki pada tanah lempung, sehingga infrastruktur yang di atasnya dapat berpeluang mengalami kerusakan. Penambahan serbuk styrofoam dan abu kayu mampu memperbaiki sifat fisis serta mekanis tanah lempung serta menaikkan nilai CBR. Mutu tanah yang sudah dicampur dengan berbagai material tambahan secara kimiawi bisa menaikkan kualitas tanah tersebut. Pada penelitian ini dilakukan pengujian menggunakan metode penambahan serbuk styrofoam dan abu kayu dengan variasi 0%, 1%, 2%, 3%, 4%, serta 5% pada berat kering tanah lempung yang ditambahkan kepada tanah dasar untuk menganalisa pengaruh penambahan bahan tersebut terhadap daya dukung. Berdasarkan hasil analisis tersebut menjelaskan bahwasannya efek penambahan serbuk styrofoam serta abu kayu pada variasi 1% dititik 1 ada kenaikan CBR 6,76%, di titik 2 CBR 6,73%, dan di titik 3 CBR 6,21% dari CBR sebelumnya. Dapat ditarik kesimpulan bahwasannya komposisi campuran tanah dasar dengan variasi 1% serbuk styrofoam serta abu kayu adalah komposisi yang baik serta perubahan nilai CBR peningkatan paling radikal diantara variasi yang lain.
Abstract: Effect of Mixture of Styrofoam Powder and Wood Ash on CBR Value of Subgrade Soil. Subgrade soil plays a vital role in road construction, including the Tepus-Jerukwudel II road. On the other hand, subgrade soil which is clay is one of the soils that has many disadvantages, including having high cohesion properties, low carrying capacity, or relatively low CBR value, because of these conditions it’s necessary to stabilize the clay soil to improve the soil properties, if no repairs are made to the clay soil, then the infrastructure on it will potentially be damaged. By adding of styrofoam powder and wood ash, the physicals and mechanical properties of clay soil are improved and the CBR value is increased. Soil quality mixed with various chemical additives can improve soil quality. In this study, tests were carried out using the method of adding styrofoam powder and wood ash with variations of 0%, 1%, 2%, 3%, 4%, and 5% on the dry weight of clay added to subgrade to analyze the effect of adding these materials on carrying capacity. Based on the results of this analysis, it is explained that the effect of adding Styrofoam powder and wood ash at 1% variation at point 1 is an increase in CBR 6.76%, at point 2 CBR 6.73%, and at point 3 CBR 6.21% from the previous CBR. From this it can be concluded that the compositions of the base soil mixture with 1% Styrofoam powder and wood ash has a good compositions and the change in CBR value is the steepest increase among the other variations.
