Access to healthcare facilities is crucial in the present day. Healthcare facilities must be proportional to the population in a given area. Therefore, it is important to increase the number of healthcare facilities in regions where there is an imbalance. Proper planning and a sustainability review are necessary when determining locations for healthcare facilities. Environmental changes can affect the suitability of a location in the future. Thus, planning that can predict future suitability conditions is required to ensure that the built locations have high sustainability. This study predicts the suitability of healthcare facility locations in 2030 in West Java using remote sensing and Geographic Information System (GIS). Both static and dynamic data processed at 30×30 meter intervals across West Java will be used. Geospatial and remote sensing data are utilized in the study. Dynamic parameter extrapolation uses data from 2000 to 2018. The random forest machine learning method is employed to obtain the suitability values for healthcare facility locations using existing health facility training data in West Java. The results show changes in the suitability classes of healthcare facilities in each region from 2018 to 2030, with some areas experiencing an increase or decrease in class. This research highlights consistently suitable locations, ensuring their sustainability as healthcare facility sites. © 2024

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.

The preparation method of cellulose films plays a vital role in their properties. This work aims to characterize 2, 2, 6, 6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized bacterial cellulose powder (TOBCP) films prepared with three different methods (casting, boiling-casting, and boiling-vacuum). It is found that film by casting (CT film) shows the best electrical properties. A light-emitting diode (LED) in a direct current circuit connected to the CT film glows the most brightly. However, this film had lower tensile strength and thermal stability than films from boiling and boiling-vacuum techniques. The boiling-vacuum film presents the most compact fiber structure and the highest tensile and thermal properties. This film also shows the lowest electrical properties and the dimmest LED light. These results demonstrate the TOBCP properties from different methods that can be used to prepare film with desirable properties. © 2024 The Author(s).

This research explores the use of a modified infrared (IR) camera equipped with a high-pass filter to distinguish between natural objects (vegetation) and artificial objects (synthetic military uniforms) in an environment where vegetation makes objects difficult to detect. In military operations, especially guerrilla warfare in tropical forests, detecting enemies camouflaged in vegetation makes it difficult to distinguish targeted objects. Visible light cameras usually struggle to distinguish between synthetic and natural colors. This methodology involves the use of Python programming and various libraries, such as Computer Vision (CV), to process images captured by modified cameras. A graphical user interface (GUI) was developed to analyze color values, focusing on the red, green, and blue spectra. The results show that the modified IR camera can more effectively separate synthetic and natural object color peaks compared to a standard visible light camera, offering potential applications in military reconnaissance and sniper operations. This research demonstrates how image processing can improve object detection in complex environments.

Indonesia is located in three collision zones of the world's three major plates, namely the Eurasian Plate, the Indo-Australian Plate, and the Pacific Plate. As a result of the plate collision, there were many earthquakes in Indonesia. One of the characteristics of the earthquake in this study is an active fault. Active faults are things that can cause earthquakes. The purpose of this literature review is to determine the differences in the accuracy of the Synthetic Aperture Radar (SAR) method with various types of satellites to identify earthquake characteristics. This literature review is limited by analysis of active faults on land using SAR imagery in the territory of Indonesia. Indonesia is located in the equator causes high cloud coverage throughout the year in Indonesian region. The advantages of this SAR image are that it can monitor the earth's surface without weather disturbances, can penetrate clouds, and can be used during the day or night. The results of this literature review show that to identify the impact of earthquakes with high slip fault sources, medium resolution SAR images can be used (such as using Sentinel-1 imagery), and to identify the effect of earthquakes with low slip faults, high resolution can be used (such as using ALOS-2/PALSAR imagery). Knowing the impact of deformation due to earthquakes can be used to improve disaster preparedness, particularly those caused by earthquakes.

Indonesia has a high tendency of having landslides. Bogor is one of regency which is very prone to landslide disaster due to high rainfall. Landslides are a very dangerous threat to public safety. The preparedness can build disaster resilient communities that can support the national resilience. Sociodemographic characteristic and disaster experience are determining factors for the success of preparedness. The purpose of this research is to develop a model of the influence of sociodemographic characteristics and disaster experience toward household preparedness for facing landslide. This research is done in Cibadak Village, Sukamakmur Bogor. This research uses a quantitative approach with 100 sample of households. Multiple linear regression technique is used for analyzing the model. The results of the research showed that household preparedness is significantly influenced by sociodemographic characteristics which is education (p = 0.000), meanwhile age, income and the number of family member don't significantly influence. Beside that the household preparedness is also greatly influenced by disaster experience too (p = 0.000). Education influence on household preparedness for facing landslide as much as 38.81% and the disaster experience is 52.85%. © Published under licence by IOP Publishing Ltd.
