Abstract

Berkembangnya perekonomian kota Jakarta diikuti oleh meningkatnya kegiatan logistik dan transportasi, dimana salah satunya ditunjukkan oleh meningkatnya kegiatan bongkar muat di pelabuhan. Kendaraan angkutan barang yang beraktifitas di pelabuhan Tanjung Priok membutuhkan tempat parkir, salah satunya di Terminal Angkutan Barang (TAB) Pulo Gebang. Saat ini utilisasi fasilitas parkir di terminal ini pada waktu-waktu tertentu cukup tinggi dan tampak memerlukan pengembangan, hal ini terlihat dari adanya parkir ganda. Berdasarkan kondisi ini, penelitian ini ditujukan untuk menganalisa efektifitas penggunaan TAB Pulo Gebang saat ini sebagai fasilitas parkir dan mengkaji potensi perbaikan utilisasinya. Dari pengamatan selama 6 hari diperoleh nilai rata-rata karakteristik parkir berupa Turn Over sebesar 0,053–0,101, Indeks Parkir 60,9%-105,5%, Indeks Aktifitas Parkir (IAP) 0,54–0,81, dan V/C ratio 45%-59%. Parameter-paramter ini menunjukkan bahwa terminal selalu dalam keadaan penuh dan terutilisasi dengan cukup efektif. Walaupun demikian, terminal masih memiliki potensi untuk dikembangkan. Potensi dilihat dengan menganalisa beberapa skenario yang mungkin diimplementasikan yaitu melarang keberadaan kendaraan tidak layak jalan, memperkeras lahan di belakang terminal, mengoperasikan pintu kedua terminal, dan mengubah sistem penerimaan kendaraan menjadi bukan sistem sewa. Dengan skenario-skenario ini, kapasitas statis terminal dapat ditingkatkan hingga 30,43%.

Abstract

This paper is aimed to develop the optimization model of time slot utilization for both runway and apron gate of airport system. The model considers the objectives of airline company to minimize flight-taxiing-time and waiting-time for both landing and take-off. The optimization makes use of Network Representation (NR) in the form of two bipartite networks in order to transform the problem of runway and apron gate assignment into the network flow problem. Maximum Matching and Minimum Cost Flow on NR are the core of the model. An illustrative example is presented. The result shows that the model could increase both runway and apron gate capacities to as close as their theoretical capacities. Compared to the common practice which concerns only; the nearest available runway slot time, behind the scheduled time, and the nearest location of available gates to serve the flight, the model could reduce the total taxiing and waiting time.

Abstract

Currently Jakarta has two freight terminals, namely Pulo Gebang and Tanah Merdeka. But, both terminals are just functioned for parking and have not been utilized properly yet, e.g. for consolidation. Goods consolidation, which is usually performed in distribution terminal, may reduce number of freight flow within the city. This paper is aimed to determine the best location of distribution terminal in Jakarta among those two terminals and two additional alternative sites, namely Lodan and Rawa Buaya. It is initialized by the identification of important factors that affect the location selection. It is carried out by Likert analysis through the questionnaires distributed to logistics firms. The best location is determined by applying Overlay Analysis using ArcGIS 9.2. Four grid maps are produced to represent the accessibility, cost, time, and environment factors as the important factors of location. The result shows that the ranking from the best is; Lodan, Tanah Merdeka, Pulo Gebang, and Rawa Buaya.

Abstract

Dampak industri 4.0 sangat besar terhadap penggunaan sumber daya manusia (SDM) akibat berubahnya teknologi yang digunakan, termasuk kehadiran kereta modern. Perkembangan teknologi kereta di Indonesia berjalan dengan cepat. SDM yang terkait dengan penyelenggaraan Perkeretaapian Modern memerlukan penambahan kompetensi agar dapat menjamin keselamatan sistem transportasi. Studi ini dimaksudkan untuk menganalisis kebutuhan standar kompetensi SDM pada sektor Perkeretaapian Modern dan mengevaluasi kesiapan Regulator dalam menyiapkan SDM-nya. Standar kompetensi diidentifikasi menggunakan Analisis Gap melalui benchmarking. Sementara itu, Analisis SWOT digunakan untuk mengevaluasi penyiapan SDM. Hasil analisis menunjukkan terdapat 6 teknologi inti dari kereta modern yang membedakan kereta modern dengan kereta konvensional, yaitu Civil infrastructure and track, Rolling Stock, Electric power facilities, Signaling and telecommunication facilities, Operation Control Center, dan ICT System. Kompetensi SDM kereta modern harus dapat mendukung penggunaan teknologi inti ini. Disusun 11 fungsi utama SDM kereta modern beserta kompetensinya masing-masing. Tambahan kompetensi mencakup aspek safety, ICT, sistem yang terintegrasi, serta budaya kerja. Analisis SWOT menunjukkan organisasi masih lemah secara internal namun memiliki peluang dari pihak eksternal. Peluang terbesar adalah adanya kebutuhan yang tinggi dari pihak industri maupun operator terhadap SDM tersertifikasi. Kekuatan yang dimiliki hanyalah dalam hal kontribusi Diklat yang cukup besar dalam memenuhi kebutuhan pasar. Hampir seluruh unsur Input-Proses-Output-Outcome Diklat yang diidentifikasi dalam studi ini masih merupakan kelemahan walau dengan tingkat kelemahan yang berbeda-beda. Kelemahan utama dari sisi Diklat yaitu terbatasnya anggaran dan juga kurangnya kompetensi SDM Regulator dan Instruktur Diklat, serta kurikulum dan silabus Diklat yang masih perlu dipersiapkan. Kualitas sarana prasarana Diklat juga masih menjadi kelemahan utama. Kelemahan utama dari sisi regulasi yaitu belum cukup siapnya SKKNI. Studi ini merekomendasikan perlunya penyiapan SDM yang memenuhi standar kompetensi , termasuk peningkatan peran dan kapasitas Diklat, peran dan persiapan Regulator, serta kebutuhan SKKNI.

Abstract

The population and economy continue to grow, as does logistic activity, as the demand for goods depends on their mutual growth. The increasing demand for goods leads to more transportation, which results in congestion and pollution. This study analyzes travel patterns and freight trip generation in Tanah Abang Trade Center. In this regard, the author identifies the characteristics of freight transportation and models the generation of freight transportation trips produced and attracted by each store. Modelling is done through linear regression analysis to determine the best model among all the formed models. The results of the linear regression produce four models that can be considered "fit," with influential variables being the number of employees and store size. The statistical findings from this model indicate that the freight trips generation is more sensitive to the variable of the number of employees. This model is developed so that planners and policymakers can benefit from the research in making decisions related to freight transportation. ABSTRAK Populasi dan ekonomi terus berkembang begitu pula dengan aktivitas logistik karena permintaan barang bergantung pada pertumbuhan keduanya. Semakin banyaknya permintaan barang maka semakin banyak transportasi yang mengangkut dan akan menyebabkan kemacetan serta polusi. Penelitian ini menganalisis pola perjalanan dan freight trip generation yang berada di Pusat Perdagangan Tanah Abang. Dalam hal ini, penulis mengidentifikasi karakteristik perjalanan angkutan barang dan melakukan pemodelan bangkitan perjalanan angkutan barang yang diproduksi dan ditarik oleh tiap toko. Pemodelan dilakukan dengan analisis regresi linear untuk menentukan model terbaik dari seluruh model yang dibentuk. Hasil dari regresi linear menghasilkan 4 model yang dapat dinyatakan “fit” dengan variabel berpengaruh jumlah karyawan dan luas toko. Temuan statistik dari model ini menunjukkan bahwa bangkitan perjalanan angkutan barang lebih sensitif terhadap variabel jumlah karyawan. Model ini dibuat agar perencana dan pembuat kebijakan dapat memperoleh manfaat dari penelitian untuk membuat keputusan terkait angkutan barang.

Abstract

The city of Banjarmasin, as the center of economic growth in South Kalimantan, faces significant challenges in terms of mobility. The development of river public transportation is one of the alternatives to overcome urban transportation problems. This study has significance in providing a holistic view of the factors that need to be considered in the selection of river transportation modes that are integrated with land transportation. The study was conducted in the areas of North Alalak Village and Sungai Lulut Village. The data processing method in this study involves testing the completeness of primary and secondary data to describe field conditions, then analyzing the preferences for choosing transportation modes using the AHP method which includes steps such as defining problems, creating hierarchical structures, conducting pairs comparisons, calculating eigenvalues and testing consistency, while the data analysis stage includes the calculation of consistency ratios, consistency vector, average of entries (Zmax) and Consistency Index (CI) to determine the final preference of each alternative. The analysis of priority weights between criteria is calculated to find out the order of the most influential criteria in selecting transportation modes. The results of the study can provide guidance for decision-making at the level of governments, transport companies and communities in developing and adopting more efficient transport systems. This research is expected to be useful for the author to expand insights, for the government and operators as input in the development of integrated transportation, and for the general public as a reference for more efficient modes of transportation.
