Abstract

This study aims to design a two-story earthquake-resistant house in Padang City with reinforced concrete structural system for columns, beams and foundations, combined with prefabricated lightweight steel roof frame. The design procedure refers to SNI 1727 2020 for minimum loads, SNI 2847 2019 on requirements for reinforced concrete and SNI 1726 2020 on seismic design procedures for buildings. 3D model was developed using sap2000 application to obtain internal forces and support reactions of the building. The foundation design was analyzed by Terzhagi’s method with consideration of the local soil conditions. The result indicate that the designed structural elements meet the strength requirements for earthquake resistant house in Padang. The use of prefabricated light steel roof frame does not significantly affect the total structural weight, but contributes to time efficiency during construction. The structural DED produced in this study is expected to serve as a practical reference for earthquake- resistant housing development in Padang. This research highlights the importance of applying seismic standards even to residential buildings.

Abstract

Ottawa sand has long been used as a standard material in geotechnical laboratory tests, particularly in grain size distribution and Sand Cone tests, due to its uniform particle size, purity, and stable physical properties. This study explores the potential of using beach sand from Nirwana and Mandeh as substitutes for Ottawa sand. The research process began with problem identification, followed by a literature review, sample collection, laboratory testing, and data analysis. The results show that the specific gravity of Nirwana sand (2.77) and Mandeh sand (2.72) are relatively close to Ottawa sand (±2.65). In terms of the coefficient of uniformity (Cu), Nirwana sand (2.34) is closer to Ottawa sand (2.17) compared to Mandeh sand (2.94). Regarding the coefficient of curvature (Cc), Nirwana sand (0.72) performs better than Mandeh sand (0.66), although both remain below the ideal range (1–3). Overall, Nirwana sand demonstrates greater potential as an alternative to Ottawa sand, with improvements in gradation recommended to achieve optimal performance.

Abstract

High-strength concrete is a crucial construction material in modern infrastructure development. It involves replacing some conventional raw materials with environmentally friendly alternatives to enhance concrete quality. Rice husk ash (RHA) is an agricultural waste that contains natural pozzolanic materials capable of improving the mechanical properties and strength of concrete. The use of rice husk ash (RHA) in high-strength concrete mixtures has the potential to reduce cement consumption and enhance crack resistance. The aim of this research is to investigate the effect of substituting cement with rice husk ash and the addition of superplasticizer on the flexural strength of concrete. The target concrete strength is 4.50 MPa, with rice husk ash substitution rates of 5%, 10%, and 15% of the cement weight. This study found the flexural strength of the concrete at 28 days to be 4.71 MPa for the 5% substitution, and 3.79 MPa for both the 10% and 15% substitutions.

Abstract

Large-scale disasters such as earthquakes, tsunamis, and floods can occur in the province of Bengkulu. The National Disaster Management Agency documented earthquake disasters of high magnitude over ten years between 2010 and 2020, with impacts ranging from casualties to infrastructure damage. To reduce the disasters' impact, community preparedness is needed. This research aims to understand the relationship between knowledge and experience of disasters with the head of the family preparedness in the face of the danger of earthquakes in the Gulf of Sepang District, Bengkulu City. The descriptive-analytical research design with a cross-sectional approach was used. The study was conducted in May-July 2022 with a population of 899 household leaders in the Gulf of Sepang District, Bengkulu City. A large sample of 90 household leaders was selected using proportional sampling techniques. The univariate and bivariate data were analyzed using descriptive and Chi-square statistics. The results showed a significant relationship between knowledge and preparedness (p-value = 0,001) with a strong coefficient contingency score (C = 0,653). There was a significant relationship between household leaders' experience and readiness (p-value = 0.001) with a strong coefficient contingency score (C = 0,603). Increasing the role of community leaders in developing community-based disaster management initiatives to reduce the impact of disasters is recommended.

Abstract

“Kolang kaling” is the endosperm of Arenga pinnata seed that contains galactomannan so it can be made into jam. This research was aimed to study the effect of “Pucuk merah” fruit juice as a natural colorant and antioxidant sources on antioxidant activity of the jam. This research used an experimental design with different levels of the juice of “Pucuk merah” fruit (6%, 8%, 10%, and 12%). Observations were anthocyanin level (pH differential method), total phenol (by Follin-Ciocalteu method) and antioxidant activity (by DPPH method) of the jam. It was found that the addition of the concentration level of “Pucuk merah” fruit juice had a statistically significant effect on the anthocyanin and total phenol level of the jam. The more the juice was added, the higher the anthocyanin level (2.82 ± 0.13 ppm; 3.76 ± 0.29 ppm; 3.88 ± 0.11 ppm; and 4.20 ± 0.52 ppm, respectively) and the higher the total phenol level (382 ± 1.53 mg GAE/100g; 431 ± 3.06 mg GAE/100g; 540 ± 1.53 mg GAE/100g and 547 ± 6.43 mg GAE/100g, respectively). By using sensory evaluation, the best product was the addition of 12% of the juice; the antioxidant activity was 628 ppm.

Abstract

The Independent Curriculum aims to form students who have the ability to think logically and critically. Therefore, this study was conducted to analyze students' high-level thinking skills (HOTS) in solving HOTS problems on Hydrocarbons and Petroleum materials. The subjects of this study are 30 students of class XI.1. The research uses a quantitative approach with descriptive data analysis. The research instrument is in the form of 8 HOTS questions in the form of descriptions. The results showed that 24% of students were in the high category, 70% in the medium category, 3% in the low category, and 3% in the very low category. Overall, the percentage of HOTS achievement is 71.35% and is included in the medium category. These findings indicate that the majority of students have not yet achieved a high level of HOTS, so a learning strategy that is more able to stimulate analytical and evaluative skills is needed.

Abstract

Buku teks merupakan salah satu media utama yang digunakan dalam proses pembelajaran untuk menyampaikan konsep kepada peserta didik. Di dalamnya terdapat berbagai label konsep yang berperan penting dalam membantu peserta didik membangun pengetahuan dan pemahaman ilmiah. Buku teks yang digunakan dalam pembelajaran harus merujuk pada kurikulum yang berlaku, yaitu Kurikulum Merdeka. Penelitian ini bertujuan untuk mengetahui tingkat kesesuaian label konsep pada materi struktur atom dan sistem periodik unsur dalam buku teks kimia kelas X Kurikulum Merdeka dengan capaian dan tujuan pembelajaran yang telah ditetapkan. Penelitian ini menggunakan metode analisis deskriptif dengan sumber data berupa dokumen capaian pembelajaran dan buku teks kimia kelas X Kurikulum Merdeka. Hasil penelitian menunjukkan bahwa secara umum terdapat kesesuaian antara label konsep dengan tujuan dan capaian pembelajaran sebesar 83%, sedangkan ketidaksesuaian sebesar 17%. Kesesuaian tersebut tampak pada keberadaan label konsep yang relevan serta kedalaman materi yang sesuai dengan tuntutan kognitif dari tujuan pembelajaran. Ketidaksesuaian ditemukan pada tingkat kejelasan label konsep serta kedalaman pembahasan materi. Berdasarkan hasil tersebut, disarankan agar guru menggunakan buku teks yang disertai dengan Lembar Kerja Peserta Didik (LKPD) sebagai pendamping dalam proses pembelajaran agar pemahaman konsep menjadi lebih optimal.
