This study aims to describe elementary school teachers’ perceptions of the use of STEM-based instructional media as an effort to strengthen 21st-century skills. The research employed a descriptive qualitative approach with the subjects being elementary school teachers in the regions of Tasikmalaya City and Regency. The population included all elementary school teachers in both areas, with a purposive sample of 50 participants. The research instrument was a Likert-scale questionnaire developed based on three indicators of STEM literacy: (1) awareness of the role of STEM in modern society, (2) familiarity with basic STEM concepts, and (3) foundational fluency in STEM application. Data were collected using an online questionnaire via google forms, while the data analysis involved calculating the average score for each indicator. The results showed that for the first indicator, teachers in Tasikmalaya City had higher awareness (average score of 4.05) compared to those in the Regency (3.93). However, in the second and third indicators, teachers from the Regency scored higher, at 3.39 and 3.67 respectively, compared to city teachers who scored 3.30 and 3.59. These findings suggest that although urban teachers have stronger conceptual awareness, rural teachers demonstrate greater mastery in understanding and applying STEM practically in classroom learning. This difference is suspected to be influenced by contextual experience and more frequent implementation of hands-on learning approaches in the Regency.

System Development Life Cycle (SDLC) is a common methodology used to develop information systems. The purpose of this study is to determine system development between the Waterfall and Rapid Application Development (RAD) models The advantage of using the waterfall method is that the quality of the resulting system will be good because the implementation is carried out in stages. The disadvantage of using the waterfall method is that the system development process takes a long time. The advantage of using the RAD Model method is that the integration of sensors/other applications can be processed faster and more effectively. The disadvantage of using the RAD method is the limitations of payment gateways, and chat bots.

Rapid development has caused changes in land use patterns, where built space increasingly dominates and pressures natural spaces to change function (Pribadi et al., 2006) explaining that changes in land use patterns result in fluctuations in the carrying capacity of land resources, giving rise to land disasters. landslide (landslide). Buol et al. (1980) and Darmawijaya (1990) explained that landslides are essentially caused by the inability of the soil to support the load above it because the soil has experienced degradation of its soil properties. The method used in this research uses a weighted scoring method. The results of the analysis of 5 parameters of potential landslide-prone areas in Tanah Datar Regency obtained 3 classifications of levels of vulnerability, namely high-level landslide-prone areas covering an area of ??2032.6955 ha, moderate-level landslide-prone areas covering an area of ??16174.395 ha and low-level landslide-prone areas covering an area of ??6284 ha. ,6345 ha. The most extensive area prone to landslides with a high level is in North Lintau Buo District. The area prone to moderate landslides is most extensive in North Lintau Buo District. The most extensive low-level landslide-prone areas are in Sepuluh Koto District.

Compressive strength is one of the mechanical properties of rock behavior. This study focuses on the Balikpapan and Kampungbaru Formations located in the Kutai Kartanegara area, East Kalimantan. The Schmidt Hammer testing method was applied due to the lack of previous studies utilizing this tool to evaluate rock hardness in correlation with compressive strength. The research site is situated in the Kutai Kartanegara area, specifically in the districts of Muara Badak, Muara Jawa, and Sanga-Sanga. Field observations revealed the presence of claystone slopes at predetermined locations. Based on the test results, the uniaxial compressive strength (UCS) values for the Balikpapan Formation range from 3.453 MPa to 5.454 MPa, while the Kampungbaru Formation ranges from 3.317 MPa to 8.571 MPa. The Schmidt Hammer rebound number (RN) values for the Balikpapan Formation range from 17 to 19.6, and for the Kampungbaru Formation from 15 to 23.7. A negative correlation was found between the rebound number and UCS, where higher RN values tend to correspond with lower UCS values. This is supported by the linear regression analysis showing a negative coefficient (-0.450).
 

The evolution of computer architecture has given rise to two main approaches: RISC (Reduced Instruction Set Computer) and CISC (Complex Instruction Set Computer). These architectures differ significantly in terms of instruction design, efficiency, and performance. This study aims to analyze the performance and efficiency of RISC and CISC in the context of computer architecture organization. The methodology includes a literature review, comparative analysis, and performance evaluation based on parameters such as processing speed, power consumption, and design complexity. The results indicate that RISC tends to be more efficient in terms of power consumption and execution speed for simple instructions, while CISC excels in handling complex instructions with fewer lines of code. The findings of this study can serve as a reference for the development of modern computer architectures that balance performance and efficiency.
