Abstract

The Premiere MTH is an apartment complex located in South Jakarta, constructed on land with a hard soil layer extending deeper than 16 meters. Given these conditions, a bored pile foundation was selected as the optimal solution. This foundation type can be tailored to the necessary depth while minimizing disruption to nearby structures during installation. A bored pile is a type of deep foundation created by drilling into the ground to a specified depth. The process involves drilling a hole with specialized equipment, inserting a steel reinforcement cage, and then pouring concrete into the hole. Special tools are used to lift and position the casing and reinforcement. Once the concrete is poured, the casing is removed. According to the design analysis, the bored pile foundations used in this project have a diameter of 800 mm, with varying depths of 30 m and 35 m.

Abstract

Hotel buildings are tall buildings that have a fairly complex design. This research will discuss the design of the upper structure of the Grand Diara Cileungsi hotel building including beams, columns, and floor plates. The design of this upper structure also takes into account the loads acting on the structure such as dead loads, live loads, and earthquake loads by using a moment-bearing frame system. This building is designed based on SNI 2847-2019 and SNI 1726-2019 to design earthquake-resistant buildings. The building structure design stage begins with the collection of structural design data which is then modeled in ETABS 19.0.2 software. After modeling in ETABS software, the design recommendations on concrete structures are as follows; 120 mm thick plate with a ratio of (0.79%), 100 mm thick plate for the roof with a ratio of (0.65%) Main Beam (350 x 650 mm with a ratio of 1.34%), Child Beam (300 x 500 mm with a ratio of 0.67%), Child beam (300 x 500 mm with a ratio of 0.67%). 67%) and sub-beams (250 x 350 mm with a ratio of 0.67%), (Concrete columns 600 x 600 mm with a ratio of 1.29%) and (400 x 400 mm with a ratio of 1.93%) with concrete quality (fc') = 30 Mpa and flexural reinforcement quality is (fy) = 420 Mpa.

Abstract

The prototype resonant frequency is designed to work at 150 MHz. The signal source prototype is the signal that comes from handy talky (HT). There are two subsystems, which are Matching Impedance and Voltage Multiplier. The resonant frequency of the matching impedance subsystem at 143 MHz from 0.053 mH inductor and 0.0233 pF capacitor. The output of the matching impedance subsystem is then amplified by the multiplier voltage subsystem using parallel PH4148 diodes with the 6-stage multiplier. Load prototype is a CR-151 LED that works at 12 volts 1 watt. When the HT battery has a voltage of 7.3 volts, the prototype can turn on the lamp with the distance between the TX antenna and the antenna on the prototype less than 36 cm. The maximum voltage on the load is 6.8 volts with a length of 5 cm between the antenna and the lamp 774 lumen.

Abstract

The damage on the Siliwangi Bekasi road is suspected to be caused by the large number of heavy vehicles passing through the road. The purpose of this study was to analyze the effect of daily traffic and vehicle load on the damage to Jalan Raya Siliwangi Bekasi. From thr calculation in this study, we can know that the Truck Factor value on the Siliwangi road from the Narogong direction to the Cut Meutia direction is 4.008 which is larger than 1 and truck factor value on the Siliwangi road from the direction of Cut Meutia to the direction of Narogong is 4.403 which is larger than 1. This indicates that road damage is caused by traffic load factors. Based on the results of the R Square test R Square value is 0.539 and 0.924, thus it can be said that daily traffic affects road damage by 53.9% and 92.4%. Based on the results of the t test between vehicle volume and road damage on highway Siliwangi Bekasi from Narogong to Cut Meutia road it is known that: The calculated t value of vehicle volume is 2,858 with Sig 0.024 and the other road section is 6,965 with Sig 0.02 we can conclude that the vehicle volume is greater than t table and the significant level of t calculated vehicle volume is less than 0.05, it can be interpreted that vehicle volume has a significant effect on road damage.

Abstract

The increasing volume of waste in Indonesia, particularly plastic waste, has led to significant environmental challenges due to its continuous accumulation. Pyrolysis offers a sustainable alternative to conventional disposal methods, such as landfilling and incineration, which are known to contribute to pollution. Pyrolysis is a thermochemical decomposition process carried out in an oxygen-deficient environment, converting plastic waste into valuable products, including gas, oil, and char. These products have various applications: the gas can be used as a fuel, the oil as a liquid fuel, and the char as a solid fuel. This study investigates the pyrolysis of three types of plastic feedstocks: high-density polyethylene (HDPE), polypropylene (PP), and a 50:50 mixture of HDPE and PP. The catalysts employed were ZSM-5 zeolite, dolomite, and a mixed catalyst comprising ZSM-5 zeolite and dolomite, with a catalyst-to-feedstock ratio of 0.2:1. The results revealed that the highest oil yields were achieved using the ZSM-5 zeolite catalyst, producing 243 ml from HDPE, 370 ml from PP, and 380 ml from the HDPE-PP mixture. Conversely, the dolomite catalyst yielded the lowest oil production, with 82 ml from HDPE, 20 ml from PP, and 282 ml from the HDPE-PP mixture. Additionally, the ZSM-5 zeolite catalyst demonstrated a consistent increase in the oil production rate every 10 minutes across all feedstocks. These findings highlight the effectiveness of ZSM-5 zeolite in enhancing oil yield during pyrolysis, offering a viable pathway for converting plastic waste into valuable energy resources.

Abstract

Cement injection under pressure, also known as grouting, is a process in which a liquid mixture is injected into cavities, cracks, and fractures in rock or soil under controlled pressure. The injected liquid undergoes physical and chemical transformations, eventually solidifying. This study aimed to evaluate the performance of various cement-water mixture designs, determine the required volume of grout based on the Lugeon number (Lv), and assess effective spacing intervals between grouting points by calculating grout effectiveness in percentages. Jet grouting, a proven method in diverse soil conditions, employs specialized equipment to hydraulically mix soil with grout, enabling soil stabilization and modification. The system is particularly effective in erodible soils, such as granular soils, and even in cohesive plastic clays. At the Mila Dam, grouting tests were conducted along the centerline of the main dam, specifically at the left abutment (Bukit Tumpuan Kiri) and the riverbed. Core drilling results from the Pilot Hole (BH-01) at a depth of 30 m revealed stratigraphic characteristics. The left abutment rock along the centerline of the dam predominantly consists of gray lapilli tuff overlaid by breccia-tuff rock units, which are brownish in color.
