This study aims to determine the capacity needs of the SRP in Hamadi Central Market, Jayapura City. The data required in the form of primary data and secondary data, quantitative and qualitative descriptive analysis approaches to analyze the characteristics of vehicle parking against the needs of SRP in Hamadi Central Market, Jayapura City. The results of the analysis of the parking volume for 92 vehicles and 164 motorcycles, the accumulated parking for 326 vehicles and 301 motorcycles, the parking duration for cars and motorbikes ranged from 1-2 hours, the parking capacity for cars was 39 vehicles / hour and for motorbikes 19 vehicles / hour, 88.3% cars and 90.4% motorbikes, 0.83 car parking turnover rates for cars / parking lots and motorbikes 1.42 motorbikes / parking lots, parking availability 267 vehicles / 9 hours and 119 motorbikes / 9 hours. The result of combining the analysis method, the need for a 46 SRP car and an 88 SRP motorbike means that it exceeds the available SRP. To answer this, an arrangement of the SRP for the car was carried out, so that the SRP for the car was sufficient because the planned SRP was 61 SRP. Meanwhile, to answer the needs of motorbike SRP, which is to move the parking lot into the market / building area, so that the SRP for motorbikes is sufficient because the SRP planned is 108 SRP. The parallel parking pattern is recommended for SRP cars and motorbikes with an angle of 90º.

The removal of alkaline chemicals, particulates, and other impurities from syngas is a challenge in the biomass gasification process. Wet scrubbers are frequently used to clean the industrial exhaust gases before being released into the atmosphere. Cleaning fluid is sprayed or pumped through the apertures and comes in touch with the gas to be cleaned of most wet scrubbers. Therefore, this paper proposes a new technology that uses a bubble wet scrubber system to flow syngas at a constant height into a pool of cleaning water. The syngas will come into direct contact with the cleaning water to form bubbles containing gas and other impurities that are absorbed mostly by the cleaning water. The objective of this study is to develop a simple and cost-effective bubble system scrubber and investigate its impact on the scrubber's performance for tar removal from biomass gasification. The results show that 2.6 L of cleaning water can remove particles and tar from syngas with an 83.26% efficiency.
