This study aims to analyze the influence of soil contour types and depths on soil characteristics using a Randomized Block Design (RBD) method. The research data were obtained from a secondary dataset encompassing physical and chemical soil characteristics across three contour types (Top, Slope, and Depression) and four depth levels (0-10 cm, 10-30 cm, 30-60 cm, and 60-90 cm). The analysis results indicate that soil contour types and depths do not significantly affect most soil characteristics, such as pH, nitrogen content, phosphorus, calcium, sodium, and soil conductivity. However, significant effects were observed on magnesium (Mg) and potassium (K) content. Conversely, area grouping showed significant effects on nearly all tested soil characteristics. These findings highlight the importance of considering geographical variations in soil management to enhance the efficiency and sustainability of agricultural practices. Further research is recommended to explore other factors affecting soil characteristics, such as climate and vegetation types, to support more optimal land management strategies.

Drought is a hydrometeorological disaster that significantly affects water availability and agricultural activities. Pesisir Selatan Regency has diverse topographic conditions that influence the level of vulnerability to drought, thereby requiring a comprehensive spatial analysis. This study aims to map drought risk by integrating slope steepness with other biophysical parameters using Geographic Information Systems (GIS). The data employed include slope maps derived from DEMNAS, rainfall data (CHIRPS 2024), soil types, land use, and river networks. The analysis was conducted through scoring and overlay methods to produce a drought risk map. The results indicate that areas with very steep slopes (>45%) have a high level of vulnerability due to surface runoff dominance and low infiltration capacity, particularly in Bayang Utara District. In contrast, flat to gently sloping areas dominated by rice fields and forest cover are relatively low-risk. Overall, drought risk in the region is classified into three categories: low, medium, and high. The resulting maps can serve as a basis for local governments in developing spatial planning policies, water conservation infrastructure, and disaster mitigation strategies that are more adaptive and sustainable.

The high pedestrian activity and traffic flow in the education area on Jalan Raya Abepura-Sentani Jayapura City led to the provision of Pedestrian Bridges (JPO) in two locations, namely in front of the Cenderawasih University Auditorium (JPO-1) and in front of SMP YPPK Santu Paulus (JPO-2). This research was conducted to determine the suitability of the physical geometric standards of the pedestrian bridge and its level of effectiveness, as well as factors that affect pedestrian satisfaction in using the two Pedestrian Bridge (JPO) facilities. Geometric analysis was carried out using the standard of Pedestrian Bridge Planning Procedures for Urban Pedestrians (1995) and Technical Planning of Pedestrian Facilities (2023), calculation of the level of effectiveness using the volume of crossings, and analysis of service satisfaction using the Importance Performance Analysis (IPA) method. The results found that the condition of JPO-2 is better and meets the standards because it uses a slope that can be used by people with disabilities, while the slope on the steps of JPO-1 is too steep (40°) and narrow with a width of 1.4 meters, so the effectiveness level of JPO-2 is higher (67%) than JPO-1 (52%). Factors affecting user satisfaction are aspects of comfort, safety, and security.  The main obstacles in using the pedestrian bridge are dirty conditions, no lighting, the presence of people under the influence of alcohol or extortionists, and damage to the Pedestrian Bridge (JPO) facilities.

A disaster is an event that can occur due to several factors and can claim lives. Indonesia is a country that has the potential for natural disasters because it is traversed by three plates. Jumok Hamlet in Sambirejo Village just experienced a landslide disaster in early 2023 which destroyed 13 houses. Land movement in Sambirejo Village can occur because the village is located on the slopes of the foot of a mountain and is surrounded by hills. This caused the Government to build and provide temporary shelter for affected victims. Apart from shelters, the government also provides household equipment for consumption throughout the fasting month. Exactly in March 2024, Group 8 students from UPNVJT carried out KKNT-MBKM in Sambirejo Village. Group 8 students were involved and worked directly with the BPBD and other institutions to provide this assistance and prepare for the HUNTARA. This article aims to provide a description of the Government's response to the disaster that occurred, providing an overview of the formation of the Huntara, and the role of group 8 who happened to be carrying out KKNT-MBKM at that time.

A slope is an area of ​​morphology that has a certain geometry, namely the highest and lowest parts and has the potential for landslides if it is in an unstable condition (Wesley & Pranyoto, 2010 in Khodijah, et al, 2022). A slope can be composed of soil, rock, or both. Slope stability is influenced by slope geometry, physical and mechanical characteristics of the slope-forming material, water (hydrology and hydrogeology), rock weak plane structure (location, direction, frequency, mechanical characteristics), natural stresses in the rock mass, local stress concentrations, vibrations ( natural: earthquakes; and human actions: effects of blasting, effects of heavy equipment passing by), climate, the results of mine workers' actions, and thermic effects (Moshab, 1997 in Arif, 2016).

Finding out how mass and slope affect the linear motion of dynamic trains is the goal of this investigation. To learn more about how variations in reach and tilt angle can impact an object's acceleration and speed, a variety of tests were conducted in this experiment with varying reach and tilt angle modifications. According to study findings, an object's speed and acceleration are greatly impacted by changes in its size. The object's speed increases in proportion to its mass because larger masses result in faster acceleration. The object's speed is, however, also impacted by variations in the track's inclination angle. An object moves more quickly at a larger tilt angle than it does at a smaller tilt angle. These conclusions are confirmed by calculations that demonstrate how an object's size affects its success. Further developments in this field can be based on the study's results, as they enhance our comprehension of the factors influencing linear motion in dynamic trains.
