Abstract

The challenges of Drinking Water Treatment Plants (DWTP) are increasing due to the presence of new types of pollutants that can contaminate raw water and increase the processing load on the installation. One of the pollutants that is currently being discussed a lot is plastic particles measuring < 5 mm which are called microplastics. Based on these factual conditions, it is also important to identify the generation of microplastics at the raw water treatment plant in Bandung-Indonesia. In this study, laboratory-scale water treatment simulations and sampling at two drinking water treatment plants in Bandung City were carried out using the grab sampling method to identify their generation in the laboratory. The results showed that microplastics were still found in all processing units, this was in line with laboratory-scale processing which showed that the processing still left residue at the final stage of the experiment. So, it can be concluded that further research is needed to optimize the performance of conventional water treatment units in removing microplastics and the mechanism that can be applied to prevent the spread of microplastics into water bodies.

Abstract

Public open space or Urban open space as a means of outdoor activities are not only become part of the lifestyle but also the needs of the community especially for people who live in urban areas with a daily work routine. One of the public open spaces is the retention basin called Embung, where people carry out various activities both individually and in groups. Here, Institut Teknologi Sumatera (ITERA) as a state university located in South Lampung Regency Lampung Province has several Embungs from Embung A, B, C, D, E, and F. Embung A is the most frequently visit due to its position adjacent to the Terusan Ryacudu street that makes it easy to be accessed not only by ITERA academicians but also by surrounding communities in the morning and afternoon. However, this location which is close to a busy highway makes it potentially get negative impacts from transportation activities, one of which is air pollution. In this research aimed to determine the perceptions of the visitors about the ambient air quality in Embung A. Our research was carried out before the pandemic, more precisely in 2019. The results of the questionnaire found that most of the visitor consider the ambient air quality is in good condition (72%) with more than half of them (59% of the respondent) said that the Embung air quality were important. The statistical analysis results show a significant result (p-value=0.001 < 0.05) between perceptions of air quality with the duration of visits. In conclusion the Embung A visitors have a good perception of Embung’s ambient air quality and its importance. Further research is needed to better understand the motives behind the visit to Embung or other public open space and their relation to other environmental parameters.

Abstract

This study aims to analyze the jointly significant influence of internal marketing, self-efficacy, and employee engagement on the achievement of the Vision and Mission of Satya Negara Hospital. A quantitative approach with path analysis method using the Structural Equation Modeling equation was used as the methodology of this study. The sampling technique was carried out by purposive sampling as much as 63 respondents. It is based on the number of health workers with permanent employee status at Satya Negara Hospital. The results show that Internal Marketing, Self-Efficacy, and Employee Engagement have a significant influence on the achievement of the Vision and Mission of Satya Negara Hospital. Partially, Internal marketing directly has a significant positive influence on the achievement of the Vision and Mission of the Satya Negara Hospital. Internal Marketing also has a partially significant positive effect on Employee Engagement at Satya Negara Hospital. On the other hand, Self-efficacy has a significant positive effect on Employee Engagement at Satya Negara Hospital partially. Self- efficacy directly has a significant and weak positive influence on the achievement of the Vision and Mission of the Satya Negara Hospital partially. Furthermore, Employee Engagement directly has a significant positive effect on the achievement of the Vision and Mission of the Satya Negara Hospital partially. Internal marketing indirectly has a significant positive influence on the achievement of the Vision and Mission of the Satya Negara Hospital through the variable employee engagement intervening. Self-efficacy indirectly has a significant positive effect on the achievement of the Vision and Mission of the Satya Negara Hospital through the intervening variable employee engagement. The findings of this study are that Employee Engagement acts as a partial mediation variable to provide a strong indirect influence on Self-Efficacy towards the Achievement of the Vision and Mission of Satya Negara Hospital. The managerial implication of this research is to improve the remuneration system and rewards obtained by health workers fairly and appropriately based on the individual performance of health workers.

Abstract

Employee performance is one of the company's primary responsibilities in achieving its goals. MSMEs are one of the options available to the community for maximizing their potential. Individuals are more motivated to pursue income due to changing environmental conditions and developing a more advanced economy. Workload, job stress, and the work environment are among the factors that can affect employee performance, especially in the micro- and medium-sized businesses in Sanur that specialize in Nogo ikat weaving. This study seeks to determine how workload, job stress, and work environment impact the performance of Sanur-based Tenun Ikat Nogo employees. This study was conducted at Tenun Ikat Nogo Sanur using a saturation sample to select a sample size of 35 employees. The 5 Likert scale questionnaire was utilized to collect data. The gathered data were then analyzed using multiple linear regression. The findings revealed that employee workload negatively and substantially affects performance. Stress at work has a substantial and negative effect on employee performance. The workplace has a substantial and positive effect on employee performance. This study will provide an empirical contribution regarding the influence of workload, job stress, and work environment on the performance of Tenun Ikat Nogo employees in Sanur.

Abstract

A one-dimensional geo-electrical method using Vertical Electrical Sounding (VES) has been carried out to model lithology and identify an aquifer, a water-bearing rock, in East Lampung to provide the water needs of the poultry breeding industry (PT. X) that is going to be established in the near future. Two VES points had been surveyed using Schlumberger electrode configuration to achieve good depth penetration and good vertical resolution. Geophysical modeling is not unique, overcoming this issue could be done using a global inversion method. A global inversion technique called Particle Swarm Optimization (PSO) was performed to create more reliable subsurface lithology, resulting in around 5 – 11% errors. The PSO algorithm deployed here took 1.000 particle numbers with ω=0.8; αl=1.8; and αg=2. The result shows that the study area’s lithology consists of Tuff, Sandy Tuffaceous, and Shaley Tuff. Sandy Tuffaceous is identified as a confining aquifer zone. There are two potential aquifer zones, Aquifer I and Aquifer II. Aquifer II has more potential as water resources of the industry due to its thickness, moreover, it is topped by impermeable Shaley tuff that prevents local climate effects such as rain that could decrease water quality.
