Abstract

KM Kirana VII is a newly operating ship, approximately two years old. Many people are interested in trying out this ship due to information they've seen on social media platforms like YouTube and Instagram. Users of fast ships come from various backgrounds, and to determine passengers' satisfaction with the fare of Rp 197,000 and the received service, an ATP and WTP analysis of KM Kirana VII is necessary.The ATP and WTP values are calculated using the household budget and perception methods. This study presents the percentage of passengers' ability to pay and willingness to pay on the KM Kirana VII route. The analysis shows that 68.39% of passengers are able to pay the fare, while 31.61% are unable. 35.48% of passengers are willing to pay the fare, while 64.52% are unwilling. There are 32.91% of Kirana ship passengers who can pay but are unwilling to pay the imposed fare. The average ATP value is Rp 211,652 per one-way trip, while the average WTP value is Rp 177,406 per one-way trip. This means that the average ATP > WTP, indicating a higher ability to pay than willingness to pay. The fare suitability based on ATP and WTP values for KM Kirana VII falls within the zone of ideal tariff determination, but service improvement is necessary

Abstract

The Pemenang-Bayan I road widening project in North Lombok Regency is part of the government's initiative to improve transportation infrastructure to support local economic growth and facilitate community mobilization. One of the biggest cost components in infrastructure projects is the operational cost of heavy equipment. In the implementation of this project, contractors have two alternatives in meeting the needs of heavy equipment, namely using their own heavy equipment or renting from a third party. This study aims to analyze the comparison between the operating costs of own heavy equipment and the cost of renting heavy equipment, focusing on two main types of heavy equipment, namely excavators and vibro compactors. This study uses interview techniques to collect analysis data. Data analysis was carried out to obtain a comparison of operational costs between the use of own equipment and equipment rental. Based on the calculation of total operational costs for earthworks in segment one (STA 0+00 - STA 1+185) of the Pemenang-Bayan I Road Widening Project, the use of self-owned heavy equipment is more economical for excavators, where the use of self-owned equipment can save operational costs of around 13.5% (Rp.2 .891,170.00 to Rp.4,336,755.00) compared to rental equipment from Cv Prayoga and save about 26% (Rp.6,723,932.00 to Rp.10,085,899.00) when compared to rental equipment from PT Trakindo Utama. As for the Vibro Compactor , the use of rental equipment is more economical than the use of self-owned equipment, which saves about 2.5% (Rp.73,479.00 to Rp.110,219.00) of the total operational cost.

Abstract

Dr. Sudjono Road is a National Road in Mataram City which is included in the collector road class, which connects various activity centers, such as educational activities, offices, economy and others. This causes the traffic flow to increase, which has an impact on traffic speed and density. This study aims to analyze the relationship between three parameters, namely volume (Q), speed (V) and density (D) of traffic according to existing conditions and find out the model that best suits the road. In analyzing the mathematical relationship between the three main variables of traffic flow, the Greenshield, Greenberg, Underwood and Bell models were used. The results show that the most suitable model is the Greenshield model compared to the other three models. So from the Greenshield model, the relationship between volume (Q), speed (V) and density (D) is obtained for the Jalan Dr. Sudjono from the East direction obtained: (Vs-D): Vs= 47.263 - 0.613× D, (Q-D): Q= 47.263 ×D-0.613×D^2, (Q-Vs): Q= 77.074×Vs–1.631×Vs2 and from the West direction obtained: (Vs-D): Vs= 56.398 - 0.846×D, (Q-D): Q=56.398 ×D-0.846×D2, (Q-Vs): Q= 66.627×Vs-1.181×Vs2. Based on a model that is suitable for Jalan Dr. Sudjono, namely the Greenshield model, the traffic flow characteristics from the East are obtained: (Qm) = 910,694 pcu/hour, maximum speed (Vm)=23,632 km/h, maximum density (Dm) = 93,624 pcu/km, free flow speed (Vsff) = 47,263 km/h and density during traffic jams (Dj) = 77,074 pcu/km and from the west it is obtained: (Qm)= 939,403 pcu/hour, (Vm) = 28,199 km/hour, (Dm) = 33,313 pcu/km, (Vsff) = 56,398 km/hour and (Dj) = 66,627 pcu/km.

Abstract

Procurement of heavy equipment requires precise analysis to avoid financial losses. Losses are usually caused by the continued use of equipment condition and value have decreased. Ignorance of the decreasing value of the equipment becomes an obstacle when submitting a tender when the latest equipment price information is needed. Heavy equipment or all goods with economic value will have a decrease in economic value. This decrease in is called depreciation. Calculating the depreciation value is very important for future calculations to avoid losses and to determine the value of the equipment after use or within a certain period. This study analyzes equipment after the construction of the Mandalika 2 Bypass Road project. In this depreciation value analysis, the method used is the straight-line method using qualitative and quantitative data. The results of this study are shown in numerical form the depreciation that occurs will be higher if the equipment is in poor condition and will produce a lower value if the equipment is in good condition. The cost of equipment after a project is highly dependent on the depreciation value of the equipment. The higher the depreciation, the lower the price. If the depreciation value is calculated based on operational costs, it will be even higher.

Abstract

The Gajah Mada road segmen in Mataram City has high activity, as well as high side obstacles. These side frictions include parked vehicles, pedestrians, non-motorized vehicles and vehicles exiting/entering. The number of side frictions will certainly affect the speed and volume of traffic moving on the undivided road with 2 lanes in 2 directions and 4 lanes in 2 directions on Gajah Mada road section. Therefore, it is necessary to conduct a study aimed at analyzing the effect of side frictions on traffic speed and volume using the MKJI 1997 method. The results of the analysis show that the highest side obstacles occur on the 2/2UD type road on Monday at 07.00-08.00 at 232.5 events /hour with the highest traffic volume of 3314.85 pcu/hour and the highest space mean speed on the 2/2UD type occurs on Saturday at 13.00-14.00 at 32,310 km/hour. Simultaneously and partially (parked vehicles, pedestrians, non-motorized vehicles and vehicles entering/exiting from the side of the road), a very strong influence was obtained between side friction and traffic speed and volume because the dominant correlation coefficient (R) was greater than 0.9 (R > 0.9) on road types 2/2UD and 4/2UD

Abstract

Altura Housing is located on Jalan Raya Mambalan, Gunug Sari District, West Lombok Regency, with coordinates -8°55'02.36‘S and 116°130'29’E. Benchmark point + 38. The housing area is a potential rice field area. The topography of the housing area is terraced with sandy loam and clay soil types. The analysis aims to determine the flood height in the housing drainage channels according to the flow direction and the Altura Housing Site Plant. The Altura Housing Complex does not yet have a safe point against flooding, whether caused by very high rainfall intensity or flooding originating from the Rainfall Catchment Area (ADT). Therefore, an analysis of the Housing Complex flood level with a 2-year return period using the Sherman Method is required. The results of the analysis of the two-year return period flood discharge using the Sherman method obtained a Q2Th of 0.878 m3/sec with a maximum rainfall intensity of 175.521 mm/hour and a drying duration of 10 minutes. And the channel construction material was designed using Yudith K225 concrete. The analysis results obtained a primary Yudith base width (B) of 1 metre, a secondary B of 0.8 metres and a tertiary B of 0.5 metres, an average slope of 0.002, a water velocity of 0.777 m/sec, and a water level in the primary channel of 0.4 m. The flood level or flood water elevation (EMAB) of the primary channel is +35.80, the secondary channel is +36.10, and the tertiary channel is +36.60. Therefore, it can be recommended that the Altura Housing Complex is safe from flooding

Abstract

Pesatnya perkembangan Kota Mataram berdampak pada peningkatan volume kendaraan di Jalan Udayana, berpotensi menimbulkan kemacetan, khususnya pada lokasi putar balik (U-Turn). Penelitian ini bertujuan mengevaluasi kinerja ruas dan fasilitas U-Turn pada dua segmen jalan melalui indikator kapasitas, derajat kejenuhan, tingkat pelayanan, waktu putar, serta panjang antrian. Metode yang digunakan adalah deskriptif kuantitatif dengan survei lapangan untuk memperoleh data primer berupa volume lalu lintas, hambatan samping, jumlah kendaraan putar balik, dan waktu manuver. Pengamatan dilakukan pada dua arah arus (Udayana–Rembiga dan Udayana–Islamic Center) di segmen 1 dan 2. Analisis data mengacu pada Manual Kapasitas Jalan Indonesia (MKJI 1997) dan teori antrian. Hasil penelitian menunjukkan derajat kejenuhan segmen 1 sebesar 0,58 (Senin) dan 0,55 (Sabtu); segmen 2 sebesar 0,53 (Senin) dan 0,51 (Sabtu)—keduanya termasuk tingkat pelayanan C (arus stabil dengan kecepatan mulai terkendali). Waktu putar di segmen 1 tercatat 11,06 detik, sedangkan di segmen 2 sebesar 11,54 detik, mengindikasikan manuver cepat tanpa hambatan berarti. Rata-rata panjang antrian di segmen 1 arah Rembiga mencapai 4,19 smp/jam, arah Islamic Center 7,52 smp/jam. Pada segmen 2, arah Rembiga sebesar 9,58 smp/jam dan arah Islamic Center 1,79 smp/jam. Hal ini mencerminkan perbedaan karakteristik antrian akibat dominasi arus dan aktivitas kendaraan yang tidak sama pada setiap arah.

Abstract

The growth in the number of vehicles in Mataram City has led to increased traffic congestion and a higher risk of accidents each year. Data from the Mataram Police Department recorded 439 traffic accident cases in 2023. This study aims to identify and map accident-prone areas using the K-Means Clustering method integrated with a Geographic Information System (GIS). The analysis was conducted using a clustering approach to group areas based on their level of accident risk, taking into account the weighted number of incidents and casualties. The quality of the clustering results was evaluated using the Silhouette Coefficient to measure cluster accuracy. The data used in this study are secondary traffic accident data from the 2021–2024 period obtained from the Mataram Police Department, focusing on arterial and collector roads. The results show that several road segments are consistently categorized as accident-prone, namely Jalan Lingkar Selatan, Jalan Ahmad Yani, Jalan Jenderal Sudirman, Jalan Sandubaya, Jalan Saleh Sungkar, and Jalan Sriwijaya. The K-Means Clustering method produced three categories of areas: “Safe,” “Moderately Prone,” and “Prone,” with Silhouette Coefficient values ranging from 0.7 to 1.0, indicating a strong cluster structure. GIS-based visualization provides a clear depiction of the distribution of accident-prone areas and can serve as a basis for the government in formulating traffic safety policies in Mataram City
