AbstrakKota Semarang dalam mewujudkan kota pintar dari sektor transportasi telah memiliki layanan IT area traffic control system (ATCS). Teknologi ATCS merupakan sistem monitoring pengendalian lalu lintas jalan berbasis teknologi informasi pada suatu kawasan di persimpangan yang bertujuan untuk mengoptimalkan kinerja jaringan jalan. Pada praktiknya, masih terdapat kendala teknis terkait suplai listrik, yakni pada saat suplai listrik PLN mati lebih dari tiga jam, maka layanan ATCS tidak berfungsi karena baterai listrik cadangan hanya mampu bertahan tiga jam. Oleh karena itu, akan dilakukan penilaian terhadap status keberlanjutan teknologi ATCS yang ditinjau dari dimensi input, proses, dan output guna memperoleh faktor/atribut yang berpengaruh pada keberlanjutan teknologi ATCS. Penelitian penilaian ini menggunakan metodologi deskriptif kualitatif-kuantitatif dengan dukungan analisis Multidimensional Scaling. Pengumpulan data dilakukan dengan observasi lapangan, wawancara dengan pengelola teknologi ATCS, dan penyebaran kuesioner kepada tiga pakar yang terkait teknologi ATCS. Hasil temuan penelitian dapat dijadikan input pada pengembangan teknologi ATCS Kota Semarang sehingga terwujud kota pintar, terutama di sektor transportasi. Hasil penelitian menunjukkan bahwa status keberlanjutan teknologi ATCS pada dimensi input menunjukkan nilai baik, dengan atribut sensitif kerangka tata kelola IT. Status keberlanjutan teknologi ATCS pada dimensi proses menunjukkan nilai cukup, dengan atribut sensitif dukungan lingkungan inovatif. Sementara itu, status keberlanjutan teknologi ATCS pada dimensi output menunjukkan nilai cukup, dengan atribut sensitif efektifitas biaya.Kata Kunci: Keberlanjutan, ATCS, Kota Pintar, Multidimensional ScalingAbstractMultidimensional Scaling Approach for Sustainability Assessment of ATCS Technology of Semarang Smart City: Semarang City in realizing a smart city from the transportation sector has had an IT area traffic control system (ATCS) service. ATCS technology is a road traffic control monitoring system based on information technology in an area at an intersection that aims to optimize road network performance. Practically, there is still a technical problem related to the electricity supply. When the PLN electricity supply has been off for more than three hours, the ATCS service is not functioning because the backup electric battery is only capable of three hours. Therefore, an assessment will be carried out to the sustainability status of ATCS technology in terms of the input, process, and output dimensions to obtain factors/attributes that affect the sustainability of ATCS technology. The research used a descriptive qualitative-quantitative method using Multidimensional Scaling analysis. Data collection was conducted by field observation, interviews with ATCS technology managers, and distributing questionnaires to three experts related to ATCS technology. The results of the research findings can be used as input for the development of ATCS technology for developing smart city Semarang, especially in the transportation sector. The results showed that the sustainability status of ATCS technology on the input dimension is good, with sensitive attributes IT governance framework. The sustainability status of the ATCS technology in the process dimension showed sufficient value, with the sensitive attributes of innovative environmental support. While the status of the sustainability of the ATCS technology in the output dimension showed sufficient value with the cost-effectiveness sensitive attribute.Keywords: Sustainability, ATCS, Smart City, Multidimensional Scaling.
