Abstract

During this time of the corona pandemic, many businesses experienced a decrease in income. This has an impact on the income that housewives earn. They complain about the increasing cost of household needs. Seeing the location in the eka kencana group, Medan johor sub-district, there is a lot of waste that can be used to use biomass energy to become a biomass stove. For this reason, the technology offered by socialization uses a biomass stove with insulation walls with a closed system, where the wood burning process is carried out in a room free from the influence of environmental air gusts. The method used in this activity is the socialization method for partner communities about the use of waste as an energy source for biomass stoves. The result of this activity is that the community can understand about the use of waste as an energy source for making biomass stoves to save expenses during the corona pandemic and take advantage of the surrounding waste and harm the local environment.

Abstract

Research is an activity to obtain a solution to a problem or phenomenon that occurs through scientific steps. To understand research, researchers must first understand what statistics are. Statistics is a science that studies the methods of collecting, processing, interpreting and drawing conclusions from the data collected or obtained. Therefore, statistics is said to be one of the sciences that is indispensable in research, not least in the field of mathematics education because statistics are used to identify and describe the relationships obtained from the data that has been collected and then processed to obtain a conclusion. The role of statistics has been seen from before the research was carried out, the research took place until the processing of research results.

Abstract

This study aims to analyze the effect of using crumb rubber (used tire powder) as a partial substitution of fine aggregate in unreinforced concrete. especially compressive strength and concrete weight. Crumb rubber variations used were 0%, 5%, 15%, and 25% of the volume of fine aggregate. Tests were conducted on 15 cm × 30 cm cylindrical specimens treated for 28 days. The main parameters tested included compressive strength and water absorption. The results showed that the addition of crumb rubber decreased the compressive strength of concrete significantly, the highest compressive strength was obtained in normal concrete (25.8 MPa), while the mixture of 25% crumb rubber produced the lowest compressive strength (3.9 MPa). However, it provides advantages in terms of lighter specific gravity and better water absorption. However, the addition of crumb rubber reduced the weight of the concrete by 19.4%. The use of crumb rubber at 5% is considered the most optimal alternative with a decrease in compressive strength that is still within the tolerance limit for non-structural concrete. This research supports the utilization of waste tires as an effort to support sustainable development. Keywords: crumb rubber, non-reinforced concrete, waste tires, compressive strength, lightweight concrete

Abstract

This study aims to design an optimal Job Mix Design (JMD) in supporting the uprating construction work of the Sunggal Water Treatment Plant (IPA) up to a capacity of 400 liters per second. The research method uses a quantitative approach with the stages of data collection, material selection, concrete composition design, and quality testing. The materials used include type I cement from Semen Padang, sand and split stone from Sei Wampu Binjai, drilled well water, and Plastiment P121R additional materials. The results showed that the optimal composition for 1 m³ of concrete K-250 consisted of 305 kg of cement, 835 kg of sand, 388 kg of 10-20 mm split, 718 kg of 20-30 mm split, 150 liters of water, and 0.92 liters of P121R Plastiment. Tests show that concrete achieves a characteristic compressive strength of 250 kg/cm² at 28 days of age with a slump value of 12±2 cm. The use of local materials contributes to transportation cost efficiency and supports the local economy. The use of Plastiment P121R as an additive improves the workability of concrete and reduces the need for water in the mixture. This research results in a concrete design that meets the technical specifications for IPA uprating construction with an efficient and sustainable approach, and can be a model for the development of water treatment infrastructure in the future.

Abstract

Penelitian ini menerapkan metode Systematic Literature Review (SLR) untuk mengkaji sifat material pengaku pada kolom baja, metode konstruksi baja, praktik konstruksi di Asia, serta perbandingan desain pengaku pada berbagai kondisi struktur. Berdasarkan pendekatan Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), sebanyak 224 artikel diseleksi dan 50 artikel memenuhi kriteria inklusi untuk dianalisis lebih lanjut. Hasil kajian menunjukkan bahwa bentuk, jenis material, dan posisi pengaku berpengaruh signifikan terhadap kapasitas aksial, daktilitas, dan ketahanan tekuk kolom baja. Pengaku tipe V dan T terbukti lebih efektif dalam meningkatkan kinerja seismik dengan peningkatan kapasitas beban sebesar 20–70%, bergantung pada konfigurasi desain yang digunakan. Praktik konstruksi di Asia didominasi oleh penerapan pengelasan elektro-slag, prefabrikasi, dan sistem Concrete Filled Steel Tube (CFST), meskipun aspek kualitas fabrikasi masih belum banyak diperhitungkan secara komprehensif. Kajian ini juga mengidentifikasi sepuluh celah penelitian utama yang dapat menjadi dasar pengembangan pedoman desain baja yang lebih efisien dan tahan gempa di kawasan Asia. This study employs the Systematic Literature Review (SLR) method to examine the material properties of stiffeners in steel columns, steel construction methods, construction practices in Asia, and comparisons of stiffener designs under various structural conditions. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach, a total of 224 articles were screened, and 50 articles met the inclusion criteria for further analysis. The findings indicate that the shape, material type, and placement of stiffeners significantly influence the axial capacity, ductility, and buckling resistance of steel columns. V- and T-type stiffeners were found to be more effective in enhancing seismic performance, resulting in load capacity improvements ranging from 20% to 70%, depending on the design configuration employed. Construction practices in Asia are predominantly characterized by the use of electro-slag welding, prefabrication, and Concrete Filled Steel Tube (CFST) systems, although fabrication quality aspects are still not comprehensively considered. The review also identifies ten major research gaps that may serve as a foundation for developing more efficient and earthquake-resistant steel design guidelines in the Asian region.

Abstract

Hadirnya etnomatematika sebagai jembatan antara konsep matematika formal di sekolah dengan pengalaman budaya siswa menjadi penting dalam mengatasi kecemasan dan kesulitan belajar siswa sebagai pendekatan yang mengintegrasikan unsur budaya lokal sebagai konteks pembelajaran. Salah satu potensi yang belum tergali maksimal adalah tradisi Mandailing Manaek Bukkulan. Penelitian ini bertujuan menganalisis potensi Manaek Bukkulan sebagai sumber kontekstual dalam pembelajaran matematika yang mengkonkretkan geometri, aritmatika, dan pengukuran melalui tradisi budaya Mandailing, sehingga siswa lebih mudah memvisualisasikan konsep abstrak. Penelitian ini menggunakan pendekatan kualitatif dengan desain etnografi etnomatematika terhadap elemen matematika dalam tradisi tersebut. Prosedur penelitian meliputi: (1) observasi partisipan intensif terhadap proses Manaek Bukkulan untuk mengidentifikasi elemen geometri, aritmatika, dan pengukuran; (2) wawancara mendalam dengan tokoh adat dan pelaku tradisi; (3) dokumentasi visual berupa foto dan sketsa bangunan adat; serta (4) analisis data kualitatif melalui reduksi, penyajian, dan verifikasi dengan triangulasi sumber.  Hasil penelitian menunjukkan bahwa Manaek Bukkulan  dapat diterapkan dalam materi geometri (bentuk dan simetri rumah), aritmatika (perhitungan bahan bangunan), dan pengukuran (luas dan volume). Implementasi ini diharapkan dapat membuat pembelajaran matematika lebih bermakna dan relevan dengan budaya siswa Mandailing.
