Abstract

The Zn(II)-pyrazinamide complex compound is currently being developed as an antibacterial agent. To obtain the Zn(II)-pyrazinamide complex effectively, many factors must be considered, including the type of zinc(II) salt and the mole ratio. The aim of this research is to examine the influence of the type of zinc(II) salt and the mole ratio in the precipitation of the Zn(II)-pyrazinamide complex to obtain efficient results. The Zn(II)-pyrazinamide complex was synthesized using a direct mixing technique in ethanol solution with metal:ligand mole ratios of 1:2 and 1:4 and with types of zinc(II) salts, namely acetate, chloride, and nitrate. Based on the research results, the anion of the zinc(II) salt leads to the precipitation of the complex while the metal:ligand mole ratio leads to the resulting yield. An efficient synthesis condition to obtain the Zn(II)-pyrazinamide complex is to use ZnCl2 salt and a mole ratio of 1:4. Experimental data also shows that the Zn(II)-pyrazinamide complex precipitate melts at a temperature of 234oC, while infrared spectroscopy analysis shows the characteristic carbonyl and amide groups of pyrazinamide. Meanwhile, powder-XRD analysis showed that the resulting complex had a different structure than that previously reported.

Abstract

Coffee plants are a factor in Indonesia's economic growth which implements an agroforestry system. Agroforestry systems and management emphasize effective agricultural systems and consider conservation of natural resources. This research aims to analyze the supporting factors for sustainable agriculture based on coffee plantations, community perceptions in developing sustainable agriculture, and community strategies for sustainable agricultural development in Kalibaru District. The research method uses quantitaive descriptive research with collection methods in the form of observation, inventory and interviews. The data analysis method is in the form of likert scale analysis and SWOT analysis. The study suggests that some communities have already understood the concept of agroforestry with a perception index found under about > 50% of the value-rating category. It deals with the influential aspects of sustainable agricultural development strategies is the natural resource of coffee plantations and community knowledge of sustainable agriculture. However, coffee community knowledge resources with a 67% education percentage in senior high schools, so that knowledge about sustainable agriculture requires moderate help and education for communities. Strategies that can be used to improve sustainable agriculture in Kalibaru District are to increase assistance and education to the community about environmentally friendly sustainable agriculture and the preservation of the agroforestry system in coffee plantations in Kalibaru District.

Abstract

Public space is a place where people can carry out their various activities. Urban public space also represents the desire of urban communities to interact with their environment. The development of the form of utilization of public space is dedinitely goes hand in hand with an increase in activity, in terms of type and intensity. The purpose of this study is to find the factors that influence the utilization of active public space on Ijen Street Corridor and Jakarta Street corridors using the Factor Analysis. The results for the factors who affects the utilization of public open space is the experience to interact with another invididual person/doing something together, and the elements that are designing of the site in public space triggering an active attachment feeling to public space in Ijen Street Corridor. While in Jakarta Street Corridor, the results are comfort level of rest by the visitors when doing their activities in the public space, achievement of the criteria of being a good public space, the experience of interacting with another users, and the level of comfort for doing some activities at the public space. Keywords: Factor Analysis, Public Space, Urban Activities

Abstract

Duck farming is a business that has been carried out for generations by the community. Even, duck farming is determined as an alternative effort to provide employment to reduce poverty in Tuban district. On the other hand intensive duck farming has potential that causes environmental problems. The purpose of this study is to evaluate and develop a strategy for implementing cleaner production to intensive a duck farming in Tuban district. The results of the trend in applying the principle of re-think, re-use and re-cycle among famers of an intensive duck farming in Tuban District show all farmers have applied three from five principles (5-R). The trend of applying the principle of recovery is still in the development stage, not all farmers apply the principle of re-deduction. While the trend of applying the re-covery principle is still very low (no farmer applies re-covery principles). The option of applying cleaner production is to ferment duck feed (the principle of re-duce) which can save feed costs of Rp. 399,750, - / month and utilization of solid waste for organic fertilizer which gives a profit of Rp. 58,700, - / harvest. The strategies for implementing cleaner production are: Socializing the concept and conducting training on the implementation of cleaner production, production management and marketing to support the implementation of cleaner production. Keywords: Intensive duck farming, Cleaner production, SWOT analysis.

Abstract

The Energy-Efficient Solar Lamp (LTSHE) initiative is a strategic electrification program implemented by the Indonesian government to deliver sustainable lighting solutions to rural communities in Sulawesi that remain beyond the reach of the national electricity grid. The program primarily targets residents in remote, underdeveloped, and isolated areas, including border regions and small frontier islands. The LTSHE system utilizes photovoltaic panels to capture solar energy, which is converted into electrical energy and stored in lead-acid batteries through a capacitor hub, subsequently supplying power to LED lamps for household illumination. To assess system performance, a photometric evaluation was conducted on a sample representing 6,018 installed systems (24,072 lamp units). As of July 31, 2018, nine units (0.037%) were randomly selected for laboratory testing. Illumination intensity was measured at three dimming levels (100%, 50%, and 10%), producing average illumination values of 31.6 lux, 15.4 lux, and 3.2 lux, respectively. Measurements at reduced dimming levels demonstrated consistent light output across samples, with values ranging from 14.4 to 14.8 lux at 50% and approximately 2.8 lux at 10%. Laboratory verification also indicated that the measured direct current injection voltage (8.10 V) exceeded the manufacturer’s specified minimum of 7.40 V, confirming the accuracy and reliability of the testing instruments. Overall, the findings demonstrate that LTSHE units provide adequate and consistent illumination, particularly at lower dimming settings, supporting their suitability for off-grid rural applications in Sulawesi. Future evaluations are recommended to standardize testing across all dimming levels to ensure comprehensive performance validation.
