To date, the study model of IT value usually takes the form of a serial construction relating its components. This paper tries to offer a parallel construction in modeling the IT value study. The applied methodology is the design-science research approach to create the construction relating its components. To perfect the construct, the paper applies the partial adjustment valuation that functions as an estimating technique to approximate and evaluate the mathematical magnitude of the performing returns of a component compared to the real figures. The developed pattern undertakes a case study with Mandiri's data, an Indonesian state-owned banking industry, shows that the estimated revenue of the parallel configuration has a deviation of only 0.28% when compared with the bank's real revenue during the period 2004-2014. Thus, the parallel configuration may appear as the alternative configuration in the study of IT value as a result of its authenticity academically as well as pragmatically. © 2020 IEEE.

Human activities have caused concerns over the contamination of trace elements in aquatic systems due to their toxicity, long-lasting nature, and ability to accumulate in living organisms. This study evaluated the spatial pattern, environmental hazard, and potential health hazard of 13 trace metals in water and sediment samples collected from the Johor River basin using multivariate statistical techniques in order to identify the impact of both natural and human-related factors on the presence of trace metals in the area. The increased levels of metals in Station S1 indicated a significant impact from municipal, domestic, and industrial waste. The Geo-accumulation Index (I_geo) values for pollution and ecological indices in the sediment of the Johor River Basin ranged from -9.44 to 6.27. The Pollution Load Index (PLI) values ranged from 0.05 to 0.18, and the Potential Ecological Risk Assessment (RI) values ranged from 2.15 to 11.18. These results indicate that the sediments in the Johor River Basin have a low risk of contamination from trace metals. The water's hazard quotient (HQ) had an average value of 0.0001, while the hazard index (HI) had an average value of 0.0003. It is important to increase stakeholders' understanding and concerns regarding the potential long-term human health and ecological implications associated with trace metals in Johor River water. The results of this study offer essential initial information for government entities to implement sustainable management strategies, reducing the likelihood of future trace metal contamination issues in the Johor River basin and similar regions. © 2024 European Regional Centre for Ecohydrology of the Polish Academy of Sciences

The utilization of hydroponic cultivation in agriculture is increasing due to its high productivity even in limited spaces. However, in practice, monitoring and controlling nutrients in hydroponic systems often require intensive human supervision and intervention. This issue can be addressed through technological advancements, particularly with the adoption of microcontrollers, sensors, and the Internet of Things (IoT). Previous research has developed IoT-based monitoring and control systems for DFT hydroponics using the Blynk platform. This study aims to develop an IoT-based nutrient monitoring and automation system for floating raft hydroponics. Floating raft hydroponics was chosen for its simplicity, lower installation costs, and space optimization. The system developed in this study uses the HC-SR04 ultrasonic sensor with an average error of 1.229%, the DS18B20 water temperature sensor with an error of 0.415%, and the TDS sensor with an error of 2.055%. The sensor and actuator measurement data are presented via the Antares Web. This research has the potential to minimize the necessity for manual intervention in hydroponic systems, thereby enhancing both efficiency and consistency in nutrient delivery. © Published under licence by IOP Publishing Ltd.

Family Planning (FP) field officers are the people actively working in the field to encourage people to get involved in the family planning program that supports the government in controlling the population of the country. However, many of the officers have stated that their recruits often make mistakes during the process of inputting data along, added with the long manual validation process. The available digital reporting application called Sistem Informasi Keluarga (SIGA) is also not used at its maximum capability, causing the decrease of data validity collected through the process. Using business process improvement (BPI), valueadded analysis, and gap analysis are performed to find the issues in the system that will become the base of the reporting system redesign. This research was done to provide a proper business process design that is needed to ensure maximum comprehension and reduction of data invalidity with the help of the existing application. The result of this research shows that the new business process design required the digitalization of the data input process using an information system and the reduction of the use of offline forms to increase the validity of data in the reporting system. © 2020 IEEE.

Planck's constant experiment has been carried out to determine the value of Planck's constant using the regression analysis method. The steps are carried out using the scientific process outlined in the practical work steps. The specification of the experimental equipment uses the Planck constant experimental set with 12v/35w tungsten halogen light, 15v output, +-0.2% accuracy, 220V power requirement, 0.5A fuse rating and red, yellow 1, yellow 2, and red color filters, green and blue. Experiments using the concept of the photoelectric effect phenomenon began by irradiating metallic materials with light using a filter. The wavelength (635, 570, 540, 500, 460) nm is the light filter variation. The wavelength that hits the metal material is selected by placing a light filter on the light propagation path toward the metal material. So the light that passes through the filter is only light with a certain wavelength. After the metal material is irradiated by light with a certain wavelength, then the stopping potential voltage measurement is carried out on the metal material irradiated by light. From the variation of the light filter used, it is possible to calculate Planck's constant using the regression method with the value obtained 6.26x1034. This value is very close to the actual Planck's constant value which is 6.62x1034 so an error value is obtained 4.23%. With 95.77% accuracy, Planck's constant value obtained from the calculation using the linear regression method can be said to be very close to the actual Planck's constant value. © Published under licence by IOP Publishing Ltd.

Organic-inorganic halide perovskites have become notable for their efficiency in light harvesting. Nonetheless, the incorporation of organic cations like $\mathbf{M A}^{+}$and $\mathrm{FA}^{+}$presents stability challenges when exposed to environmental factors. This study explores the potential of replacing organic components with inorganic $\mathrm{Cs}^{+}$to enhance stability and efficiency in PSCs, focusing on CsPbBr 3 as the light harvester. We compare spin-coating and spray-coating techniques for depositing SnO 2 as the electron transport layer, revealing that spray-coating 7 cycles achieves higher PCE. Through detailed characterization, including UV-Vis, FTIR, SEM, I-V, and IPCE analyses, we optimized the manufacture of $\mathrm{SnO}_{2}, \mathrm{CsPbBr}_{3}$, and carbon deposition at room temperature, resulting in a PCE of $\mathbf{2. 2 1 \%}$ using the spray-coating process, demonstrating significant improvements over the spin-coating method.
