Abstract

Salah satu aditif pada beton adalah Bestmittel dimana termasuk bahan tambah golongan type E (water reducing and accelerating admixture) yang berfungsi mempercepat pengerasan, mengurangi pemakaian air dan meningkatkan workability. Tujuan penelitian ini untuk mengetahui pengaruh Bestmittel terhadap kuat tekan beton dan mengetahui persentase kenaikan kuat tekan beton normal terhadap kuat tekan beton Bestmittel dengan nilai koefisien menggunakan Peraturan Beton Indonesia (PBI 1971). Benda uji berbentuk silinder dan jumlah 30 buah, variasi umur pengujian beton yaitu 3 hari, 7 hari, 14 hari, 21 hari, dan 28 hari. Variasi dosis penambahan Bestmittel yang digunakan 0,4% dari jumlah semen, serta pengurangan jumlah air 10%. Hasil pengujian kuat tekan beton normal pada umur 28 hari sebesar 25,653 MPa dan kuat tekan beton Bestmittel sebesar 29,615 MPa. Persentase kuat tekan beton Bestmittel umur 14 hari sudah mencapai sebesar 96%. Berdasarkan nilai Koefesian PBI 1971 bahwa kuat tekan beton mencapai 100% jika umur beton 28 hari, sedangkan Beton menggunakan bahan tambah Bestmittel pada umur 21 hari dan 28 hari berturut-turut 105% dan 115%. Hal ini membuktikan bahwa dengan penambahan aditif Bestmittel 0,4% dan pengurangan jumlah air 10% meningkatkan kuat tekan beton, dan mempercepat proses pengerasan beton di umur muda dengan arti bahwa Bestmittel memiliki pengaruh yang signifikan terhadap kuat tekan beton.

Abstract

The Edu-Eco-School Program was implemented as a community service activity at SMPS Khazanah Boarding School, Pujud District, with the aim of optimizing school land through the cultivation of food crops and vegetables supported by a water-efficient irrigation system. This program is significant as it aligns with the Sustainable Development Goals (SDGs), particularly Zero Hunger and Climate Action, which emphasize food security and water resource conservation in education. The implementation stages included land condition surveys, the design and construction of a bore well and PVC pipe network as an irrigation system for plant watering, agricultural training, and mentoring up to the harvesting stage. The program successfully transformed underutilized land into a productive garden with various commodities, such as chili, tomato, corn, and vegetables. The harvest not only met the school’s basic needs but also served as a contextual learning medium for students to practice sustainable agriculture. Overall, this program enhanced school community engagement, improved water-use efficiency, and created a productive green area that supports local food security while strengthening environmental education.

Abstract

The potential of local wood and the large amount of wood waste from the wood processing industry and window and frame businesses in Aur Sati Village, Tambang District, Kampar Regency, need to be utilized by the community so that training is needed to utilize local wood potential to support the tourism sector for youth groups and PKK mothers in the village. The purpose of this activity is to assist in optimizing processed wood waste to add economic value, and it is hoped that the results of this activity can provide knowledge and technology for utilizing local wood resources so that in the future it will be able to increase community income to support the tourism sector. The activity results have been applied as decorative table products from Durian tree trunks that are no longer productive and processed wood waste from the community. The products produced in terms of visual appearance have distinctive characteristics and look classic, so they will have a fairly high selling price. The results of this community service activity are in the form of assistance to the target audience in the form of training/counseling on making decorative tables from pieces of Durian tree trunks that are no longer productive and processed waste from the community.

Abstract

Aur Sati Village is one of the newly formed communities in Kampar Regency, Riau Province. Some administrative tasks, such as archive management, can improve village government services to the community. Village archives are currently stored manually and need to use digital archiving methods. Digital archive management can be used as a storage place for documents and can help overcome the lack of computer equipment owned by village officials. This program aims to increase the knowledge of village administrators regarding digital archive management (e-filing). The implementation of the e-filing program for Aur Sati Village officials is very useful in carrying out their administrative duties. There are three steps to the program: planning, implementation and success assessment. A survey with local leaders was part of the preparation step. An initial presentation, pre-test, and training on digital records management (e-filing) were conducted during the implementation phase using an app scanner, Google Drive, and Google Sheets. Village governments were given a post-test questionnaire to measure their skills during the evaluation phase. As a result, village governments showed a good understanding of e-filing and its management. Based on the post-test evaluation, most village officials and administrative staff in Aur Sati Village are able to digitally archive official letters (e-filing) and reduce the possibility of losing archives in the future.

Abstract

Concrete is one of the main construction materials widely used in infrastructure development due to its high compressive strength and good durability. However, achieving optimum compressive strength in concrete requires a relatively long curing time, around 28 days. To overcome this issue, additives such as Bestmittel are used, which function to accelerate the hardening process and increase the compressive strength of concrete at an early age. This study aims to determine the effect of adding 0.5% Bestmittel on the compressive strength of concrete at curing ages of 3, 5, 7, 15, and 28 days. The specimens used were cylindrical with a diameter of 15 cm and a height of 30 cm, and three samples were prepared for each variation. Based on the test results, the compressive strength of normal concrete at 28 days was 26.31 MPa, while the compressive strength of concrete with Bestmittel at 3, 5, 7, 15, and 28 days was 20.47 MPa, 25.65 MPa, 25.94 MPa, 27.63 MPa, and 32.16 MPa, respectively. At 7 days, concrete with Bestmittel almost reached the strength of normal concrete at 28 days, with a percentage of 98.58%, and at 15 and 28 days it exceeded the strength of normal concrete with percentages of 105.03% and 122.24%, respectively. The results show that the addition of 0.5% Bestmittel is effective in accelerating early-age strength gain, making it highly suitable for use in construction projects that require high strength within a relatively short time.

Abstract

Aursati Village has considerable potential for the development of Danau Bokuok tourism, yet faces limitations in providing creative local products that reinforce the destination’s identity. The absence of facilities that showcase local characteristics has reduced the area’s attractiveness. This community service program aimed to strengthen tourism through the diversification of local furniture products utilizing wood waste and the natural forms of unproductive durian and rubber tree stumps. The program consisted of four stages: preparation through coordination and scheduling; program socialization and product education; technical training in crafting decorative furniture using local materials combined with resin; and the handover of products to the village for use as tourism support facilities. The results demonstrated improved knowledge, skills, and active participation of the community, particularly village youth, in creative production. The products developed not only offered aesthetic value but also reflected a strong local identity. This program is expected to stimulate sustainable village-based creative enterprises and foster a tourism-driven local economy. Moreover, the activity strengthened community awareness and a sense of ownership in tourism development, ensuring continued contributions and long-term impact.
