<![CDATA[Sugarcane (Saccharum Officinarum), as a raw material sugar-making process, is the essential component for the sugar industry, including PT XYZ. Sugarcane is a perishable good with 48 hours shelf life after being cut from the garden; if it exceeds the shelf life, the sugarcane yield will decrease. The random pattern of truck arrivals causes a queue of trucks within the factory. This study aims to reduce the average waiting time of entities in the system using discrete simulations. Discrete-event simulation is used to capture changes in variables and has been widely used to solve queuing problems. We developed four scenarios to seek the better solution. Scenario 1 is to shift the location of the sugarcane unloading tables 1 and 2. Scenario 2 is to add one location for unloading the sugarcane table. Scenario 3 adds the function of unloading small ankle trucks and large ankles on sugar cane loading tables 4 and 5. Scenario 4 is developed by combining scenarios 1 and 3. The results show that the reduction in average waiting time of scenario 1: long truck 15.9 minutes and small ankle truck 124.6 minutes; scenario 2: small ankle truck 5.5 minutes; scenario 3: small ankle truck 95.5 minutes; scenario 4: small ankle truck 163.3 minutes and long truck 13.1 minutes.  Based on those scenarios, scenario 4 obtained the best solution with a total decrease the average truck time in the system of 176.4 minutes or 8% better than existing system. Tebu (Saccharum Officinarum) sebagai bahan baku pembuatan gula menjadi komponen paling penting bagi industri pengolahan gula, termasuk PT XYZ. Tebu bersifat perishable dengan masa simpan maksimal selama 48 jam setelah ditebang dari kebun, dan jika melebihi waktu simpan maka kadar rendemen tebu akan menurun. Pola kedatangan truk yang acak menyebabkan timbulnya antrean truk dalam pabrik. Penelitian bertujuan untuk mengurangi antrean truk dengan indikator pengurangan rata-rata waktu tunggu entitas dalam sistem menggunakan simulasi diskrit.

<![CDATA[Traffic congestion in Indonesian cities is a major problem, due to uneven mobility. The Jagir Wonokromo intersection, one of the busiest intersections in Surabaya, experiences traffic congestion during rush hour. This congestion can have a variety of negative impacts, such as air pollution and queuesat each intersection. This study analyzes the traffic congestion problems at the Jagir Wonokromo intersection and proposes the appropriate improvement scenario. A simulation design was developed to test three traffic congestion improvement scenarios at the Jagir Wonokromo intersection in Surabaya. The study sample was 40 vehicles that passed through during rush hour. The simulation results showed that scenario 3 is the most appropriate improvement scenario. This scenario successfully reduced the time in the system by 20.2% compared to the initial condition. The impact of scenario 3 is that traffic congestion at the intersection is reduced, but the travel time of vehicles from the DTC direction to Jalan Jagir Wonokromo also increases. Scenario 3 is considered to be in accordance with the conditions of the intersection and can be easily implemented. The study of traffic congestion at the Jagir Wonokromo intersection offers opportunities for the government and the public to address traffic congestion with effective simulation of improvement scenarios.]]>
