On Friday 26 June 2020, Singgih Hartanto has successfully defended his dissertation paper entitled Urban Spatial Planning Model on Electric Energy Distribution, in a closed doctoral promotion session at the UNDIP Architecture and Urban Science Doctoral Program in front of a team of examiners led by Prof. Dr. Ir. M. Agung Wibowo, MM, MSc., PhD, as Dean of the Faculty of Engineering, Diponegoro University. Born in Tuban, the man has been directly guided by Prof. Dr. Ir. Sugiono Soetomo, DEA, as the Promoter along with Dr. Drs. PM Brotosunaryo, MSP, and Dr. Ing. Wisnu Pradoto, ST, MT, as the Copromoter during his research process related to energy issues, especially electrical energy in urban areas. To the internal and external examiners, Singgih Hartanto explained the background of his research problem related to energy losses due to increasing urbanisation and urban development in Indonesia. His presentation explained that the occurrence of electrical energy losses technically in urban areas in the distribution of changes in urban spatial patterns and the location of energy sources that are not spatially integrated (uncompact) due to the absence of service area coverage limits or buffers. In order to eliminate the occurrence of electrical energy losses in urban areas, a model of urban spatial planning with efficient distribution of electrical energy is needed. Semarang City was chosen as the research focus. The compact city theory and spatial infrastructure theory that form the structure and spatial pattern become the basis of the research in the form of variable types and parameters that affect it. The spatial function of the compact city theory variable is the high density of built-up land, while the infrastructure theory variable is the range of services. The measure of compact land density and the extent of service coverage complement the compact city theory with the findings of an urban planning model. His research uses a positivistic quantitative paradigm with independent variables (spatial pattern location distance and energy consumption), dependent variables (substation), moderator variables (z-score), intermediate variables (area and buffer) and control variables (energy shrinkage).

Despite the Covid-19 pandemic, online through MS Team media, the man who was born on 5 February 1972 was able to convince the external examiner, Ir. Gusti Ngurah Antaryama, Ph.D., who was invited from the Sepuluh November Institute of Technology (ITS) Surabaya, that through land use projection analysis using cellular automata and Landuse Sim programmes, electrical energy load projection analysis using the DKL 3.2 method from PLN, and spatial pattern distribution analysis using ANN (Average Nearest Neighbor) analysis and energy losses calculation using ETAP (Electrical Transient and Analysis Program) software. This man who is active as the Deputy Chairperson of DPN INKINDO has explained the novelty of his research related to the compact city spatial pattern planning model for electrical energy distribution, and hopes that this planning model is useful for urban planning science, especially spatial planning and electrical energy infrastructure that can reduce the number of electrical energy losses spatially.

As a lecturer in the Department of Urban Planning at USM in Semarang, Singgih Hartanto actively writes scientific articles that are presented at national and international seminars related to his scientific field, especially related to energy in urban areas. Some of the scientific works of the 55th doctor of PDIAP UNDIP which are quite phenomenal are articles entitled Model of Electricity-Efficient Buildings Location Pattern in Simpang Lima Compact Commercial Cluster and have been published in the Scopus indexed Horizon Research Publishing USA journal. Thus, the UNDIP Architecture and Urban Science Doctoral Program led by Dr. Ir. Atiek Suprapti, MT, has succeeded in producing a doctorate cum laude, whose research is concentrated in the urban infrastructure scientific family.
