Kemacetan yang sering terjadi pada simpang Jalan Syekh Umar Khalil-Bypass Kota Padang menimbulkan terjadinya antrian dan tundaan pada salah satu simpang yang sangat panjang. Maka dilakukanlah evaluasi dan perencanaan lampu lalu lintas untuk mangatasi permasalahan yang terjadi. Survei dilakukan dengan merekam lalu lintas kendaraan dengan menggunakan kamera yang ditempatkan pada persimpangan. Pengambilan data dilaksanakan selama enam jam setiap hari selama dua hari kerja, yaitu 2 jam pagi hari (pukul 07.00 – 09.00), 2 jam siang hari (pukul 12.00 – 14.00), dan 2 jam sore hari (pukul 16.00 – 18.00) pada hari Senin dan Kamis. Kemudian tiap jalur dibagi menjadi beberapa sektor sesuai dengan arah jalan per 15 menit. Dari data per 15 menit tersebut direkap dalam 1 jam, lalu diambil jam puncaknya untuk dianalisa. Perhitungan parameter perencanaan berdasarkan MKJI 1997. Hasil yang didapat pada kondisi eksisting untuk nilai derajat kejenuhan masing-masing pendekat Utara, Selatan dan Timur telah melewati batas jenuh (DS>0,75), sehingga diusulkan 4 jenis perancangan untuk meningkatkan kinerja simpang. Alternatif 1, pelebaran jalur pendekat, alternatif 2, pengaturan simpang menjadi 2 fase, alternatif 3, pengaturan simpang 2 fase dan pelebaran sedangkan alternatif 4 adalah dengan menutup simpang. Hasil perhitungan menunjukan, perencanaan optimum adalah alternatif 3 dan 4.

Road works are almost close with moving traffic and potentially causing traffic disruption, congestion, delay, frustration, and more can cause collisions that would injure or kill road users and road workers. In order to remain resilient, the road worker must apply the zone concept on road works. This study aims to evaluate the application of Safety Technical Guidance on Road Work Location conducted by PT. Citra Muda Noer Bersaudara on Road Reconstruction of Junction (Koto Baru) - Jambi Border segment. So do a direct observation of the road work zone implemented by the contractor and compare it with the applicability in the guide. The implementation of the road work zone carried out by the contractor on the work package under review still lacks. In the implementation, the lack of which always occurs in every job implementation is the absence of a termination zone in all types of work, the transition zone is only applied to asphalt work, the early warning zone is only applied to road concrete work, asphalt overlay work and road shoulder work. Speed survey results show that the implementation of road work zone applied by the contractor can reduce the speed of the vehicle.

Driving behaviour has been studied by numerous researchers for the past few years. It includes the instantaneous driving behaviour observations and the drivers speed which are said to be influenced by many factors, such as the demographic measure of the drivers, environmental, passenger effect, and road characteristics. This paper describes the recent analysis and classification of driver behaviour in actual driving scenarios among the bus drivers in Universiti Malaysia Sabah (UMS) Main Campus, Kota Kinabalu. This research focussed on determining the riderships of bus in UMS campus, to investigate the differences of instantaneous driving behaviours of bus drivers during the acceleration phase when leaving bus stops, and to poduce the classification of the bus driving behaviour in UMS based on the driver’s accelerations. In order to achieve the objective of this study, observations were made for determining the riderships and the differences in instantaneous bus driving behaviour several times for each bus stops. For drivers speed and accelerations, a mobile applications called Speedometer GPS was used to obtain the data. Interview was conducted to a total number of 10 respondents to obtain their demographic measure. The results obtained shows the ridership of UMS bus is the highest in the afternoon peak. The instantaneous driving behaviour produce the head movement as the highest percentage during peak hour, and inattentive behaviour as the highest during the off peak hour. The bus drivers in UMS were classified as Aggressive and Calm Behaviour Category.

Sawah Lunto – Talawi road segment (STA 139 + 700 m) in Sawah Lunto city, West Sumatera province has sustained major damages and been the scene of several accidents since the past few years. The degression of soft clay subgrade, which has a limited bearing capacity and makes it structurally impractical to sustain road construction, was discovered to be the source of these damages. As a recent option for enhancing soil qualities, soil stabilization by employing a variety of pozzolanic and industrial materials has gained popularity. The objective of this study is to investigate the effectiveness of Portland cement type 1 as stabilizing material in improving the soil properties and carrying capacity requirements for soft clay soil used as subgrade in road construction. To accomplish the objectives of this study, a laboratory testing procedure was implemented. Unconfined Compressive Strength (USC) values on natural soil and treated soil with Portland cement type 1 admixture were measured and compared during laboratory experiments. Soft clay soils were stabilized with varying percentages of Portland cement type 1 with the proportions of approximately 1%, 2%, 3%, 4%, 5%, 6%, 7%, and 10% by dry weight of soil during a 7-days curing period. Laboratory testing were performed in compliance with Indonesian National Standard (SNI): SNI 3420-2008 for testing Unconfined Compressive Strength. According to the results of laboratory testing, the UCS values increased roughly from 0.634 kg/cm2 (undisturbed natural soil) to 2.832 kg/cm2 (treated soil) by adding 3% of Portland cement type 1, and up to 8,024 kg/cm2 (treated soil) by adding 10% of Portland cement type 1. Based on the findings, it can be demonstrated that Portland cement type 1 can enhance clay soil's properties used as a subgrade for road construction, can create more stable road conditions, and can ultimately meet the technical feasibility requirements for the subgrade carrying capacity, particularly at the Sawah Lunto - Talawi road segment (STA 139 + 700 m).

Indonesia has the many area of the lime production including in the West Sumatra Province. The use of lime as a filler in asphalt mixtures is expected to improve the performance of asphalt mixtures. There are two types of lime used, namely Palupuh and Rao-Rao limestone. This study aims to see the effect of using these 2 types of lime as a filler on Asphalt Concrete-Wearing Course (AC-WC) pavements mixture. The bitumen used is Pen 60/70. Marshall testing was carried out to see the characteristics of the pavement mixture. From Marshall's testing on a pavement without lime, has an optimum asphalt content of 6.015%. Furthermore, with a variation of lime 0%, 25%, 50%, 75%, 100% by weight of filler for both types of lime gave an optimum lime content yield of 50% with an increase in stability of 12.024% and flow of 19.375% for Palupuh lime. Meanwhile, the use of Rao-Rao lime cannot improve the Marshall stability of the AC-WC pavement mixture

The rising fuel prices on September 3, 2022, are expected to reduce the use of private cars and increase the use of public transport. This expectation has raised optimism among public transport operators and is expected to encourage them to invest more. However, there is no evidence to support the expectation. Therefore, it is essential to study the effect of the fuel price on the use of a particular transport mode, thus motivating this study. This paper aims to investigate the impact of the rising costs of subsidized fuel on private cars. A Likert-scale type of questionnaire was used to collect data. The data was analyzed descriptively, and then a conclusion was made based on the results. The study found that the daily commute of respondents changed after fuel prices increased. Distance, duration, and frequency of travel tend to be reduced and prioritized over primary activities. To reduce travel costs, the respondents who usually use cars are more likely to use motorcycles than public transport. The findings of this study disprove that an increase in fuel prices would increase the use of public transport. Why is public transport less favoured compared to motorcycles? It seems that the quality of service provided by public transport fails to satisfy the consumers' needs.

Landslides are Indonesia's second most common disaster in the last ten years. Landslides cause losses, reaching hundreds of billions and threatening human safety. For this reason, it is necessary to take action to reduce the negative impact of landslides. Physical and non-physical mitigation can occur before, during, and after a disaster. The most essential thing in disaster mitigation is knowing the major factors that cause landslides. This research aims to analyze the major and minor factors that cause landslides using the Analytical Hierarchy Process (AHP) and the Likert scale. Respondents in this research are experts in disasters, especially landslides—respondents from universities in Indonesia, practitioners, and people involved in disaster mitigation. Validity and reliability tests were carried out on each question used in the questionnaire. The research results show that the landslide disaster was caused by a disruption in balance that occurred due to internal and external disturbance factors. The major external factors that cause slope failures are the cutting of hills and changes in land use to built-up areas. In contrast, the major internal factors that trigger landslides are heavy rainfall and steep topographic conditions. The results of this research in the form of weight and scoring values for each factor causing landslides can be used as a reference for mapping landslide areas to identify areas with the potential for landslides.
