In this paper we developed a VRP model for multiple routes, multiple time windows for multiple products and heterogeneous vehicles. The solution were constructed using a heuristic approach, i.e, a sequential insertion algorithm. Additionally, this model is applied to solve fuel distributions for eight customers in East Nusa Tenggara. It needs two tankers with capacity of 4700 kilo liters, so that those distributions can be accomplished with a minimum number of vehicles, total completion time, and range of completion time. The result of this study shows that for a heterogeneous vehicles problem, a vehicle with the largest capacity may not necessarily be the vehicle that provides an optimal solution. Moreover, advance trials should be conducted by providing a limited number of tankers for each tanker capacity, so the description of heterogeneous vehicles becomes more visible. In the future research, the solution will be improved by utilizing relocation techniques.
Program Studi Teknik Industri (PSTI) adalah salah satu jurusan di Fakultas Teknik Universitas Diponegoro. Pada tahun 2015 PSTI telah memiliki gedung baru sebagai sarana perkuliahannya. Seiring dengan hal itu PSTI juga mendapatkan aset-aset penunjang perkuliahan seperti komputer, meja, kursi dan lain-lain. Namun pengelolaan aset di PSTI saat ini tidak berjalan dengan baik, PSTI tidak mempunyai database aset khusus untuk mempermudah pengelolaan dan penelusuran asetnya. Pengelola aset di PSTI selama ini hanya menggunakan pendataan menggunakan Excel untuk mendata ketersediaan asetnya dan itu juga sudah lama tidak diperbarui. Banyak aset di PSTI yang tidak memiliki nomor inventaris yang telah di berikan oleh Unit Layanan Pengadaan (ULP) Fakultas Teknik. Hal ini menyebabkan susahnya melakukan penelurusan aset. Permasalahan ini sering menyebabkan pengelola aset di PSTI sulit untuk mengetahui kondisi aset itu baik, rusak maupun hilang. Hal tersebut membuat proses penggantian aset PSTI yang rusak di ULP menjadi tidak maksimal. Oleh karena itu, dibutuhkan suatu sistem informasi yang dapat menjalankan proses bisnis manajemen aset menjadi rapi dan terstruktur sehingga pengelola aset jurusan dapat dengan mudah untuk melakukan pengelolaan dan penelusuran aset. Proses perancangan Sistem Informasi Manajemen Aset (SIMA) dimulai dengan identifikasi sistem pengelolaan aset yang berjalan saat ini di PSTI dan membuat sistem baru yang diusulkan. Selanjutnya dari sistem usulan tersebut dirancang DFD (Data Flow Diagram) serta ERD (Entity Relationship Diagram) dan juga desain antarmuka sistem informasi tersebut. Dari tahap perancangan tersebut kemudian dihasilkan sebuah Sistem Informasi berbasis website untuk mengelola aset di PSTI. Selanjutnya dilakukan verifikasi dan validasi untuk mengetahui kesesuaian rancangan sistem dengan hasil akhir SIMA yang telah dibuat. Bagian akhir penelitian ini adalah membandingkan sistem lama dengan sistem baru untuk mengetahui perbedaan yang terlihat setelah diimplementasikannya sistem baru tersebut. ABSTRACT Program Studi Teknik Industri (PSTI) is one of the departments in the Faculty of Engineering, University of Diponegoro. In 2015 PSTI has had a new building to support lesson activity. Along with it PSTI also get lectures supporting assets such as computers, desks, chairs and others. However, asset management in PSTI is currently not running well, PSTI has no special asset database to simplify the management and tracking of assets. PSTI asset manager at this time only use data collection using Excel to record the availability of its assets and it also had not updated. Many assets in PSTI do not have an inventory number that has been given by the Unit Layanan Pengadaan (ULP) Faculty of Engineering. This condition make difficult for searching their asset. These problems often lead to asset managers in the PSTI is difficult to determine the condition of the assets is good, broken or missing. This makes the process of replacing damaged assets PSTI in ULP be no maximum. Therefore, needed an information system that can run the asset management business into a neat and structured asset management department can be easy to perform management and asset tracking. The process of designing Asset Management Information System (SIMA) begins with the identification of an asset management system that is currently running in PSTI and make the proposed new system. Furthermore, of the proposed system is designed DFD (Data Flow Diagram) and ERD (Entity Relationship Diagram) and also the information system interface design. From the design stage and then produced a web-based information system to manage assets in PSTI. Further verification and validation to determine the suitability of the design of the system with the end result of SIMA have been made. Last is comparing the old system with a new system to determine the differences that looks after the implementation of the new system.
Varying characteristics of developed and developing countries have resulted in different challenges and innovative solutions of city logistics. This study aimed to identify research clusters on city logistics between developed and developing economies and to systematically compare city logistics challenges and associated innovative solutions for both economies. Bibliometric analysis and a systematic literature review were applied to analyze 328 peer-reviewed publications, comprising 229 (70%) and 99 (30%) articles addressing case studies in developed and developing economies, respectively. We discovered six research clusters in city logistics literature for developed countries, compared with only four for developing economies in which public policy has not been addressed. Urban growth, environmental challenges, and traffic congestion are the three major city logistics challenges in both types of economies. Furthermore, fleet increment and inadequate loading/unloading spaces are the city logistics challenges analyzed in the literature on developing countries compared with the literature on developed economies that addresses the challenges of education deficiency, regulation, emergence of new business models, and network accessibility and capacity. Consequently, innovative solutions adopted by developed countries demonstrate varied processes involving technology, policy (including public policy and sustainability measures), infrastructure, and economic measures, while for developing countries, the focus remains on effective and efficient distribution operations using optimization and collaboration efforts.
Indikator adalah ukuran kuantitatif dan kualitatif yang menggambarkan tingkat pencapaian suatu sasaran atau tujuan yang telah ditetapkan. Fakultas Teknik Universitas Diponegoro yang merupakan Fakultas terbesar sekaligus sebagai penyumbang hasil riset terbesar setiap tahunnya telah mempunyai Renstra 2015-2020 sebagai pedoman. Didalam Renstra tersebut terdapat IKFT, yaitu indikator-indikator untuk mengukur kapasitas FT serta pencapaian FT setiap tahunnya. Indikator khusus untuk menilai kapasitas riset dan pencapaian riset masih minim dan masih perlu dikembangkan. Penelitian ini bertujuan mengembangkan indikator kunci untuk menilai kapasitas riset Fakultas Teknik Universitas Diponegoro. Kapasitas riset dapat ditinjau dari empat faktor utama keberlanjutan penelitian yaitu antara lain : faktor keuangan, manajemen organisasi, pendukung riset dan infrastruktur. Dalam penelitian ini terdapat sembilan indikator kunci yang dikembangkan dari jurnal dan sumber literatur lainnya. Terdapat 11 KPI sumber Renstra FT UNDIP, 9 KPI yang dikembangkan. Indikator tersebut digolongkan sesuai faktor keberlanjutan penelitian antara lain : 6 KPI faktor financial, 3 KPI faktor manajemen organisasi, 6 KPI pendukung riset dan 5 KPI infrastructure. Setelah dikembangkan dilakukan penilaian dengan terlebih dahulu melakukan pembobotan KPI menggunakan metode AHP dan kemudian dilakukan scoring dengan metode OMAX. Hasil dari penilaian tersebut didapatkan Indeks Pencapaian setiap kategori antara lain yaitu : financial 7,906, manajemen organisasi 5,628, pendukung riset 4,713 dan infrastruktur 8,171. Berdasarkan penilaian tabel OMAX setiap kategori didapatkan 7 KPI yang posisi lampu merah, 4 KPI yang posisi lampu kuning dan 9 KPI posisi lampu hijau. Tahap selanjutnya dirancang rekomendasi perbaikan dari beberapa literatur untuk meningkatkan kapasitas riset dan kemudian divalidasi dengan menggunakan metode delphi.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
