Implementation of the Supervision Function on Public Sector Employees (Study at PT. PLN's South Sulawesi, Southeast Sulawesi and West Sulawesi Regions)

Good supervision is needed at the Office of PT. PLN (Persero) in the South Sulawesi, Southeast Sulawesi and West Sulawesi Regions so that employees can work effectively and produce optimal work. The purpose of this study, is to analyze the supervisory function carried out at PT. PLN (Persero) South Sulawesi, Southeast Sulawesi and West Sulawesi Regions. This research method uses quantitative research with descriptive research type. Data collection techniques using questionnaires in the form of a checklist and using descriptive analysis techniques. The results of the study showed that the direct supervision conducted was quite good, while the direct supervision was quite good

Analysis of User Perceptions of Transport Service Performance in Makassar City

Changes in the arrangement of transportation system services in Makassar City must be made immediately in realizing public transportation systems that meet the expectations and needs of the community. There are problems with the performance of Pete-Pete's public transport services in terms of reliability, comfort, security, generosity, and timeliness of pete-pete public transport in Makassar City. The purpose of this study is to analyze the description of users' perceptions of public transport and examine the effect of reliability, comfort, security, generosity and timeliness on the performance of public transport in Makassar. This research uses a quantitative approach with data collection techniques through observation, questionnaires and in-depth interviews and documentation studies. The research sample of 150 people as respondents. This study uses SEM analysis with the SmartPLS package program ver. 2.0 ME, to estimate the model, study and test hypotheses. The results of this study indicate that (i) There is a positive influence on the reliability factor on the performance of Pete-Pete transportation in Makassar City, with a contribution of 44.30% (ii) There is a positive influence of comfort factor on the performance of Pete-Pete transportation in Makassar City, with the contribution of 26.35%, (iii) There is no positive effect on the performance of the Pete-Pete transportation performance in Makassar City, with a contribution of only 0.78%. (iv) There is a positive influence of the factor of mercy on the performance of Pete-Pete transportation in Makassar City, with a contribution of 54.23% and (v) There is a positive influence of the timeliness factor on the performance of Pete-Pete transportation in Makassar City, with a contribution of 60.50%

Semi-supervised regression using diffusion on graphs

Indexación ScopusIn real-world machine learning applications, unlabeled training data are readily available, but labeled data are expensive and hard to obtain. Therefore, semi-supervised learning algorithms have gathered much attention. Previous studies in this area mainly focused on a semi-supervised classification problem, whereas semi-supervised regression has received less attention. In this paper, we proposed a novel semi-supervised regression algorithm using heat diffusion with a boundary-condition that guarantees a closed-form solution. Experiments from artificial and real datasets from business, biomedical, physical, and social domain show that the boundary-based heat diffusion method can effectively outperform the top state of the art methods. © 2021 The Author(s)https://www-sciencedirect-com.recursosbiblioteca.unab.cl/science/article/pii/S1568494621001113?via%3Dihu
