Abstract

Meulaboh Busines area on Jalan H. Daut Dariah II is a busy area with trade activities, especially during rush hour. Parking activities around the Meulaboh market especially on Jalan H. Daud Dariah I is so high that the shoulders and road bodies are filled with parking cars, motorcycles, tricycles, and street vendors. In addition, the pedestrians cross the road and the number of motor vehicles coming in and out of the center of the market as well as the slow moving vehicles like bicycles, tricycles and carts. This causes the road width to be less effective so that the speed of traffic becomes low and there is traffic congestion. The purpose of this study is to analyze the effect of side barriers on the speed and flow of lalulitas and the factors that predominantly influence side obstacles are in and out vehicles, parking vehicles and street vendors. Side obstacle data, speed and traffic volume was taken directly by conducting survey for 7 days and analyzed by using Manual of Capacity of Road Indonesia 1997. From result of calculation hence side barrier influence highest happened at period time clock 09.00 - 10.00 this is caused by the number of vehicle The parking and the vehicles going in and out, at this condition the speed of the vehicle decreased to 20.62 km / h for two-wheeled vehicles or tricycles and for the speed of four-wheeled vehicles of 15.82 km / h with traffic flow of 274.64 smp / hour. To increase the speed and traffic flow on the road H. Daud Dariah I then need to be provided in the parking lot so that vehicles are no longer parked on the road and pedangang pedestrians should sell at places that have been provided by the government. Keywords : obstracle, speed, traffic flow

Abstract

The application of warm mix asphalt technology to reduce mixing and compaction temperatures has a weakness in decreasing the performance of mixture and is more sensitive to high temperatures. This is influenced by the type of additives and the warm mix asphalt technology used. The purpose of this study is to determine the optimum percentage of Rediset®LQ used and the amount of temperature drop in the type of Pen 60/70 asphalt mixture. Determination of the percentage of optimum use of the Rediset®LQ was carried out by using mixed workability analysis. The results of the warm mix asphalt test are then compared with the control HMA, the volumetric value that is close to the control HMA is considered to have equivalent workability. The variation of the use of the Rediset®LQ is 0.25% to 0.75% with a variation of the mixture temperature reduction of 15 ºC, 30 ºC, and 45 ºC. The results showed that the optimum percentage of using Rediset®LQ on asphalt pen 60/70 was 0.5% with a large reduction in mixing temperature and optimum compaction of 30 ºC. Evaluation of the resilient modulus value of the WMA mixture is equivalent to the HMA mixture at low, medium, and high temperatures. Based on the analysis, the Warm Mix Asphalt Concrete Binder Course with Rediset®LQ additive, also lower mixing and compaction temperature, is suitable for use on pavement layers.

Abstract

Teuku Umar University (UTU) is a public university located in West Aceh Regency. The number of active students at UTU was recorded as 6,636 in the academic year 2021-2022. Currently, the UTU campus lacks public transportation serving its vicinity. This study aims to identify the daily activities of UTU students in commuting to the campus and to determine the extent of students' response to the implementation of public transportation services within a ±5 KM buffer zone from the UTU campus. This research utilizes two types of data analysis methods, namely qualitative descriptive and quantitative descriptive. The research findings indicate that 93.5% of students strongly agree with the concept of implementing public transportation, and 75.3% of students agree to switch from private vehicles to public transportation. The majority of daily travel activities are conducted by female students, accounting for 54% compared to 46% of male students. The modes of transportation used to reach the campus are motorcycles (56%), bicycles (6%), and walking (38%). Regarding the frequency of departure times to the campus, 41% of students depart at 08:00 AM, 23% at 09:40 AM, 15% at 10:30 AM, 12% at 11:20 AM, 6% at 01:50 PM, and 3% depart at 04:20 PM. As for the frequency of return times, 16% return at 01:30 PM, 21% at 11:20 AM, 34% at 01:50 PM, 10% at 03:30 PM, 16% at 04:20 PM, and 3% return at 05:10 PM. Based on this study, we recommend developing a dedicated public transportation service concept for UTU students. Data on students' daily activities can serve as crucial input for the future development of public transportation projects.

Abstract

Choosing the right type of fertilizer is a crucial factor in increasing rice productivity. Problems often faced by farmers are a lack of understanding of the nutritional content of fertilizers and limited access to credible agricultural information. To overcome these challenges, this research aims to develop a Decision Support System (SPK) based on the Weighted Product (WP) and Rank Order Centroid (ROC) methods to help farmers choose the best fertilizer. The ROC method is used to determine the weight of criteria based on priority ranking, while the WP method is used to evaluate and rank fertilizer alternatives based on predetermined weight values. The criteria used in this study include nitrogen, phosphorus, potassium, sulfur, organic content, price, and availability in the local market. The fertilizer alternatives analyzed are: Urea, SP-36, ZA, NPK Phonska, KCL and Petroganik. The test results show that NPK Phonska is the best fertilizer alternative, followed by ZA and Urea.

Abstract

This research aims to describe the communication strategy used by the Ombudsman RI of West Sulawesi Province in an effort to increase public participation in public services supervision in West Sulawesi. This research was conducted in the Office of Ombudsman RI of West Sulawesi Province which is located in Mamuju Regency, West Sulawesi Province. This research used qualitative approach with case study method. Data were collected through in-depth interviews, observation, and documentation. The results of this study indicate that the SIMBA PVL programme carried out to various regions can increase public participation in terms of accessing complaint services at the Ombudsman RI of West Sulawesi. Only there are still weaknesses in socialisation related to the procedures for receiving complaints through digital media which shows that public participation through this access is very low. The obstacles found are the lack of employees owned by the Ombudsman RI of West Sulawesi Province to oversee the entire Public Service sector in West Sulawesi and the demographic conditions and characteristics of the Complainant in West Sulawesi. While the supporting aspects found are the existence of communication and good relations between institutions and the solidity of the work team so that it has a positive impact on the Ombudsman in carrying out its duties and authorities in West Sulawesi Province. This study recommends that the Ombudsman RI of West Sulawesi continue to improve the report acceptance programme that can reach community access to areas that are difficult to reach with electronic communication in West Sulawesi and further examine the strategy of using digital media in terms of access to report acceptance in West Sulawesi.
