Abstract

The high population and density of cities in Indonesia raise a number of urban problems that require creative and innovative solutions. One of the steps taken by the municipal government is to implement the concept of smart city, one of which is by utilizing information and communication technology (ICT). The municipal government applies ICT by creating websites and applications to provide a variety of city information and municipal government services to all residents that can also be shared on their online social network. However, it is not clear whether the residents perceive that the provided information is useful and whether the intentions to seek and share information from smart city platform are influenced by the perceived usefulness of the information and the citizen’ online social network attributes. Hence, this study was conducted with the aim to analyze the effect of the perceived usefulness of smart city information and social network attributes (number of ties and diversity of ties) on intention to seek and share information on smart city websites and applications in cities in Indonesia. The data were collected using a survey method, involving 1,161 respondents in 8 major cities in Indonesia, namely Jakarta, Bandung, Surabaya, Semarang, Medan, Makassar, Denpasar, and Banjarmasin. The survey results were analyzed using partial least square structural equation modeling (PLS-SEM), and it is concluded that the perceived usefulness of smart city information and the residents’ online social network attributes have positive and significant effects on the intention to seek information and intention to share information on smart city websites and apps.

Abstract

Toll Corridor Development (TCD) is one of the businesses conducted by PT Jasamarga Related Business as a follow-up to the issuance of Peraturan Menteri Pekerjaan Umum dan Perumahan Rakyat (PUPR) No. 28 of 2021. In the development of its first TCD project, Jasamarga Related Business (JMRB) encountered issues that resulted in the delay of the project's completion. The purpose of this research is to analyze and make improvements to the causes of delays in the Taman Mini TCD project. In this research, the lean six sigma approach is used to analyze process improvements that can be carried out so that these problems can be minimized in the further development of TCD. To identify activities that cause delays in the implementation of this project, the critical path method (CPM) was used based on the results of interviews with those directly involved in the development of TCD project. From the activities that cause the delay, a causal analysis is carried out using a fishbone diagram, and then an analysis of possible improvements is carried out using a lean concept approach. Based on the analysis results, three main issues are identified, namely inadequate planning process, ineffective partner or consultant selection process and delays in construction completion. From the cause-and-effect analysis, it can be concluded that potential improvements can be made by implementing the concept of pull planning, improving the business process by reducing waste and enhancing value-added activities, establishing effective stakeholder management, and maximizing the use of technology-based applications to aid project control.

Abstract

Kualitas layanan sangat mempengaruhi tingkat kepuasan pelanggan dan mendukung daya saing perusahaan. Tingkat kepuasan pelanggan dapat dilihat dari sejumlah keluhan atau komplain yang muncul. Penelitian ini bertujuan untuk mengetahui komplain apa saja atas layanan PT. XYZ dan penyebab komplain tersebut. Penelitian ini menggunakan metode Six Sigma dengan pendekatan DMAIC (Define, Measure, Analyze, Improve and Control) untuk melakukan perbaikan kualitas layanan PT. XYZ. Data diperoleh melalui survei pelanggan perusahaan untuk mengukur persepsi kualitas layanan berdasarkan variabel Reability, Assurance, Tangible, Empathy dan Responsiveness dan melakukan wawancara dengan manajemen dan karyawan PT. XYZ serta pelanggan untuk mengidentifikasi masalah yang dihadapi. Berdasarkan hasil Pareto Chart diperoleh komplain terbanyak adalah kenyamanan kendaraan, keamanan pengemudi mengendarai kendaraan, kebersihan kendaraan, kebersihan pool, kenyamanan pengemudi dan jaminan keaman dalam perjalanan. Penyebab utama masing-masing komplain tersebut adalah usia kendaraan lebih dari 4 tahun, penjadwalan pengemudi tidak tepat dan tidak ada petugas khusus kebersihan. Rekomendasi perbaikan yang akan dilakukan adalah melakukan peremajaan kendaraan, evaluasi penjadwalan pengemudi dengan menyesuaikan jadwal keberangkatan dan menambah petugas khusus kebersihan pool.
