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

This Wireless Analog to Digital Data Logger research aims to design a prototype measuring tool that is useful for converting analog data into digital data, or an Analog to Digital Converter (ADC), without using cable media (wireless), where the communication media used in this research is Bluetooth by using the HC-05 module and Arduino Uno as the main control system. The system output of the measurement results in this research is displayed on the Android phone in the form of decimal numbers to make it easier to read, along with the date, month, and year, as well as the time when the measurement was taken. This system is also equipped with a graphic display of measurement results in real time, making it easier for users to monitor changes in data that occur visually. This measuring tool also has a facility for storing measurement data in the form of an Excel file with CSV (comma separated values) format, which can be downloaded from the data storage media on the Android phone used, making it easier for users to process or retrace the measurement data on other media such as computers.

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

Islamic Hospital Surabaya as a Class B Hospital has collaborated with BPJS since 2014. Preparing the tariff pattern used in serving BPJS patients is very important, especially regarding quality and cost control. To do this, hospitals must be able to serve BPJS patients by taking into account existing pricing patterns so that there are no losses in treating patients. To prepare for this, it is necessary to refresh knowledge regarding unit costs and hold a workshop to increase knowledge and calculate unit costs. This workshop is expected to provide additional knowledge to participants regarding hospital business management in determining pricing patterns based on unit cost calculations. The method used in this workshop is to use lecture, case study and simulation methods. 48 participants took part in the workshop with evaluations consisting of pretests and posttests. One important element in streamlining a company's production process is the concept of cost per unit, which can help companies ensure that the costs they incur will be lower than the selling price of one unit. This workshop is very beneficial regarding unit cost calculations, this can be seen from the results of the pretest and post-test calculations with an increase in value of 15% and there is a significant difference between the pre-test and post-test based on the results of the Paired Sample T-Test.

Abstract

Kemampuan literasi dan numerasi merupakan fondasi utama pembelajaran abad ke-21 yang menentukan kualitas sumber daya manusia di masa depan. Namun, hasil PISA 2022 (OECD, 2023) menunjukkan bahwa capaian literasi dan numerasi siswa Indonesia masih berada di bawah rata-rata negara OECD. Kondisi ini lebih nyata di wilayah pedesaan seperti Kabupaten OKU Timur, di mana keterbatasan sumber belajar, minimnya inovasi pembelajaran, serta kurangnya pendekatan kontekstual menyebabkan rendahnya minat anak dalam membaca dan berhitung. Kearifan lokal, yang mencakup permainan tradisional, simbol budaya, dan cerita rakyat, memiliki potensi besar sebagai sarana edukatif untuk memperkuat kemampuan literasi dan numerasi sekaligus menumbuhkan kesadaran budaya. Berdasarkan pemikiran tersebut, kegiatan pengabdian kepada masyarakat ini dirancang untuk mengintegrasikan unsur budaya lokal Desa Nirwana ke dalam aktivitas pembelajaran literasi dan numerasi. Pendekatan yang digunakan bersifat partisipatif dan kontekstual melalui kegiatan membaca, menulis, berhitung, serta permainan edukatif berbasis budaya lokal. Tujuan utama kegiatan ini adalah meningkatkan kemampuan dasar anak sekaligus menghidupkan kembali nilai-nilai budaya masyarakat setempat. Dengan mengaitkan pembelajaran pada konteks kehidupan sehari-hari dan warisan budaya lokal, kegiatan ini diharapkan mampu meningkatkan motivasi belajar, memperkuat keterampilan berpikir kritis, serta memperluas pemahaman anak terhadap makna literasi dan numerasi dalam kehidupan nyata.
