Abstract

Aviation has become an important aspect in human life thanks to its ability to transport people to faraway places with short duration and relatively low cost. However, aviation activities are highly influenced by uncertain events such as weather conditions. One of the activities that is impacted by these 2 events is turnaround operations. Turnaround operations is an activity performed to prepare aircraft for the next flight. This research aims to evaluate and improve turnaround operations performance both from relative duration tardiness (?T%) and on-time performance (OTP) using discrete-event simulation approach. Results obtained from simulation model show that the value of ?T% is 43.48% and OTP of 54.20%. Improvement scenarios are developed by arranging the new ground support staff (GSS) schedule and allocation as well as adding GSS at a certain rate. Scenario of implementing new schedule and allocation and adding GSS with rate of 50% comes out as the selected scenario which could improve ?T% and OTP performance to become 33.35% and 54.91% respectively. Aviasi telah menjadi aspek yang penting bagi manusia karena kemampuannya untuk membawa manusia ke tempat yang jauh dengan durasi singkat dan biaya yang relatif rendah. Akan tetapi, kegiatan aviasi sangat dipengaruhi oleh kejadian yang tak pasti seperti kondisi cuaca. Salah satu kegiatan yang terdampak oleh kedua kejadian ini adalah turnaround operations. Turnaround operations merupakan kegiatan yang dilakukan untuk mempersiapkan pesawat untuk penerbangan selanjutnya. Penelitian ini bertujuan untuk mengevaluasi dan memperbaiki kinerja turnaround operations baik dari sisi durasi keterlambatan relatif (?T%) maupun on-time performance (OTP) menggunakan pendekatan simulasi kejadian diskrit. Hasil yang diperoleh dari model simulasi menunjukkan bahwa nilai ?T% sebesar 43.48% dan OTP sebesar 54.20%. Skenario perbaikan dikembangkan dengan menyusun penjadwalan dan alokasi ground support staff (GSS) yang baru dan penambahan GSS dengan tingkat tertentu. Skenario dengan menerapkan jadwal dan alokasi baru serta penambahan GSS sebesar 50% keluar sebagai skenario terpilih yang mampu memperbaiki nilai ?T% dan OTP menjadi 33.35% dan 54.91% secara berturut-turut.

Abstract

ABSTRAK Sebuah lini produksi dirancang untuk memastikan bahwa aktivitas produksi berlangsung lancar dengan output maksimal. Namun, kelancaran lini produksi dapat terganggu jika terjadi bottleneck dalam aktivitas atau proses tertentu, yang dapat menurunkan tingkat produksi secara signifikan. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis bottleneck dalam lini produksi industri makanan menggunakan pendekatan simulasi. Hasil simulasi kondisi eksisting menunjukkan bahwa proses packing menjadi bottleneck utama. Melalui skenario perbaikan berupa kombinasi penugasan mesin manual packing yang lebih fleksibel dan penambahan konveyor, simulasi membuktikan bahwa throughput produksi per jam dapat meningkat sebesar 8,6%. ABSTRACT A production line is designed to ensure that production activities run smoothly and achieve maximum output. However, its smooth operation can be disrupted if a bottleneck occurs in certain activities or processes, significantly reducing the production rate. This research aims to identify and analyze bottlenecks within a food industry production line using a simulation-based approach. The simulation results of the existing conditions indicate that the packing process is the primary bottleneck. Through an improvement scenario involving a combination of more flexible manual packing machine assignments and the addition of conveyors, the simulation demonstrated that hourly production throughput could increase by 8.6%.

Abstract

Digital transformation in public services has become a key strategy to improve efficiency, accessibility, and environmental sustainability. The Government of Indonesia has designated the acceleration of public service digitalization as a national priority to realize inclusive, transparent, and environmentally friendly services exemplified by the City of Surabaya, which has implemented massive digitalization efforts since 2019. This study evaluates the environmental impact of digitalizing the “Pindah Keluar” (Out-Migration) administrative service, one of the services provided by the Department of Population and Civil Registration (DISPENDUKCAPIL) in Surabaya, using a Life Cycle Assessment (LCA) approach. The study compares four service system phases: the manual system (SIAK), LAMPID, KLAMPID, KLAMPID during the COVID period, and the fully digital service (KLAMPID Online). The LCA results show that digitalization significantly reduces paper consumption and transportation-related emissions, with the total environmental impact score decreasing from 87.83 mPt in the manual system to 32.67 mPt in the fully digital system. However, digitalization also leads to increased electricity consumption and reliance on digital infrastructure, indicating a shift in environmental burden from the community (in the form of physical activities such as paper use and transportation) to the service provider institution (in the form of energy consumption by digital infrastructure). These findings highlight that achieving sustainable digitalization, from an environmental burden perspective, requires internal system efficiency and the adoption of environmentally friendly energy sources to minimize the total ecological footprint generated by public service providers.
