Abstract

This research aimed to identify the earthquake hazard, developing a peak ground acceleration (PGA) and earthquake intensity map to reduce earthquake disaster risk in Malang, East Java, Indonesia. This map is based on historical data of earthquake occurrence in 2011-2021 using the International Seismological Centre (ISC) earthquake catalog. Peak ground acceleration was analyzed using Donovan and McGuire equation, and the earthquake intensity was analyzed using the Wald equation. The result of this study represented peak ground acceleration value in Malang Regency, which was varied from 23.687 – 33.069 gal (Donovan attenuation equation) and 22.245 – 31.705 gal (McGuire attenuation equation). While based on earthquake depth, Malang Regency had a damage capacity of IV-V MMI on an intensity scale. This intensity was equivalent to the formation of cracks in the ground. Almost all residents also feel the vibrations. The most severe damage was due to the earthquake on April 10, 2021, at 14:00:16 WIB spoiled Dampit and Bantur district's public facilities. This study provides an overview of the riskiest area affected by the disasters that can be used for disaster mitigation in Malang regency.

Abstract

Information technology is a very important part of the organization. IT is expected to provide a good profit for the company. However, as technology evolves, it is often exploited by some irresponsible parties that can lead to the emergence of threats and risks from the use of technology. The organization needs to measure the level of information security to identify the system's weaknesses and threats to the organization. Standards for measuring information security are COBIT 5 subdomain manage security services (DSS05) and NIST SP 800-55 revision 1. This study is comparing the two standards. Comparative analysis uses qualitative analysis based on three aspects in information security that are confidentiality, integrity, and availability. Based on the analysis result obtained the advantages and disadvantages of each standard.

Abstract

This study aimed to prepare the readiness of students to use E-learning media in the MBKM (Freedom to Learn – Independent Campus) program at the Faculty of Science, Technology and Education. This was an evaluation research with a quantitative research approach and descriptive method. The data collection technique used lecturer and student questionnaires based on the CIPP evaluation model (context, input, process, product). The samples were 98 students. The results indicated that in terms of readiness and understanding of E-learning-based learning management, the lecturers were included in the high category with a percentage of 87.78%. The score obtained by students based on the understanding of E-learning-based learning was included in the high category with a percentage of 82.16%. The results of the questionnaire showed that the E-learning-based learning activities were carried out well (structured, according to schedule and coordinated).

Abstract

The Space and temporal distribution of the seismicity parameters consisting of magnitude of completeness (Mc), a-value, and b-value were estimated for the East Java, Indonesia using the International Seismological Center (ISC) earthquake catalogue. The main purposes of this research were to determine the parameters of the seismicity and its spatial temporal distribution so that early detection and warning systems in the East Java run optimally. All estimated parameters were analyzed based on an earthquake catalogue during 1980-2020 by applying The Maximum Curvature (MaxC) method. The MaxC method enumerate the highest value of the first subordinate of the cumulative Frequency Magnitude Distribution (FMD) graph. The value of the magnitude of completeness, which was estimated on this study as result Mc 3,4 – 4,8; a-value 5,560 - 8,244; and b-value (0,73 – 0,82 ± 0.13). The lower b-value (0,73 ± 0.13) was obtained for the southern part of the East Java. This area is indicated to have high seismic moment release and rock stress level accumulation. Understanding and clarifying the relation between seismicity parameters and structure of tectonic framework can guidance us to estimate seismic risk for earthquake hazard mitigation in the East Java.

Abstract

Elementary school students cannot visualize virtual objects or images on some social studies materials in a real environment. This study aims to develop 7 Wonders of the World-APP-based Augmented Reality media to improve elementary school student's mastery of concepts. This study used the four-D method and used a pretest-posttest control group design. Methods of data collection using questionnaires and tests. Validity includes the validity of teaching materials, design validity, and learning media validity from two experts. Data analysis techniques using descriptive qualitative analysis, quantitative, and inferential statistics. The results showed that the proportions of the validity test of learning materials, the validity test of the learning media design, and the validity test of the learning media got a very good category. The results of the t-test show significant differences in students' mastery of concepts. Media 7 Wonders of the World-APP, based on Augmented Reality, is very suitable and effective for learning media in elementary schools for social studies.

Abstract

Sistem pendukung pengambil keputusan untuk seleksi penerima beasiswa di Universitas Muhammadiyah Lamongan, melalui LAZISMU (Lembaga Amil Zakat, Infaq, dan Sadaqah Muhammadiyah), menggunakan metode Multi-Attribute Utility Theory (MAUT). Metode MAUT mempertimbangkan preferensi subjektif dan bobot atribut dalam pengambilan keputusan multi-kriteria. Sistem ini menghitung skor utilitas total untuk setiap calon penerima beasiswa dengan menggunakan bobot atribut dan nilai atribut yang diberikan. Penelitian ini mengambil sampel data dari 18 mahasiswa dan menggunakan lima kriteria pilihan. Lima kriteria tersebut meliputi nilai tes (bobot 0,15), jenis beasiswa (bobot 0,4), nilai IPK (bobot 0,2), kontribusi lembaga Muhammadiyah (bobot 0,15), dan organisasi (bobot 0,1). Hasil perhitungan menggunakan metode MAUT menunjukkan bahwa sistem ini berhasil memberikan nilai utilitas tertinggi sebesar 0,9667 dan terendah sebesar 0,2333. Sistem ini membantu LAZISMU dalam menyeleksi calon penerima beasiswa secara efisien dan objektif, sehingga calon penerima beasiswa dengan skor utilitas tertinggi dapat direkomendasikan sebagai penerima beasiswa.

Abstract

Robot transporter memiliki peran penting dalam mengangkut barang atau material dari satu lokasi ke lokasi lain secara efisien. Rumah sakit, sebagai pusat distribusi farmasi yang penting, membutuhkan sistem kontrol yang presisi untuk pengaturan yang efektif. Dalam penelitian ini, kami menerapkan sistem kontrol PID yang dilengkapi dengan sensor ultrasonik untuk mengatur pergerakan robot transporter. PID, yang terdiri dari Komponen Proporsional (P), Integral (I), dan Derivatif (D), menunjukkan efektivitasnya dalam memastikan operasi yang lancar. Melalui antarmuka Excel, parameter output utama seperti Waktu, Jarak (cm), dan status operasional termasuk Akselerasi, Pengereman, dan Berhenti. Rentang nilai jarak yang tercatat mulai dari 0 hingga 375 cm memberikan wawasan tentang gerakan robot dan kinerja sensor ultrasonik di bawah berbagai kondisi. Stabilitas sistem, terbukti dengan nilai tegangan yang konsisten dalam rentang 2,12 hingga 10,8 volt, mencerminkan stabilitas keseluruhan selama pengujian. Penerapan kontrol PID menghasilkan hasil yang konsisten dan dapat diandalkan dalam mengatur pergerakan robot transporter dengan efektif
