Abstract

Beton memiliki sifat dasar, yaitu kuat terhadap tegangan tekan dan lemah terhadap tegangan tarik. Selain sifat dasar tersebut, beton juga memiliki sifat kekedapan dan keawetan. Sifat-sifat ini sangat dipengaruhi oleh Bahan penyusun beton Pengerjaan beton Perawatan beton Umur Beton. Metode penelitian ini adalah pengujian yang dilakukan yaitu uji kuat tekan beton Kuat tekan beton hasil analisa menggunakan nilai rata-rata yaitu beton perawatan laboratorium dengan nilai K’bL  =  380.32 kg/cm2  >   300 kg/cm2, beton perawatan lapangan adalah K’bF  =  299.05 kg/cm2    300 kg/cm2 dan  beton tanpa perawatan adalah  K’bU  =  269.21 kg/cm2  <   300 kg/cm2 . Kuat tekan beton hasil analisa menggunakan regresi yaitu beton perawatan laboratorium adalah K’bL  =  379.38 kg/cm2   >   300 kg/cm2 ,beton perawatan lapangan adalah K’bF  =  296.67 kg/cm2     300 kg/cm2 dan beton tanpa perawatan yaitu  K’bU  =  277.61 kg/cm2   <   300 kg/cm2 Kunci : Perawatan, Kuat Tekan, Beton

Abstract

Concrete is a building material consisting of a mixture of cement, water, fine aggregate, coarse aggregate in a certain ratio. With the number of buildings that use concrete, the demand for concrete increases, and the use of aggregate as a supporting material for concrete increases as well. Innovation in concrete-forming materials can be done by substituting substitute materials, either aggregates or other materials by utilizing the waste that is around us. One of the wastes that can be used around us is brick waste. From the above phenomenon, the researcher will innovate on the concrete constituent materials by utilizing waste bricks as a substitute for fine aggregate to find out how much the compressive strength of concrete is at the age of 7 days and 28 days. The effect of adding brick powder to the concrete mixture resulted in a decrease in the compressive strength of the concrete. The higher the percentage of brick powder added to the concrete mixture, the lower the compressive strength of the concrete will be

Abstract

Penelitian ini membahas tentang Masalah keselamatan dan kesehatan kerja (K3) secara umum masih sering terabaikan. Tujuan dari manajemen risiko adalah untuk mengenali risiko dalam sebuah proyek dan mengembangkan strategi untuk mengurangi atau bahkan menghindarinya, dilain sisi juga harus dicari cara untuk memaksimalkan peluang yang ada. Pada penelitian ini akan diteliti mengenai identifikasi risiko K3 (Keselamatan dan Kesehatan Kerja) yang berkaitan dengan kegiatan proyek pembangunan Pembangunan Gedung Parkir dan penilaian risiko-risiko K3 (Keselamatan dan Kesehatan Kerja) yang terjadi pada kegiatan proyek pembangunan Pembangunan Gedung Parkir. Dalam penelitian ini akan digunakan metode penilaian risiko dengan menggunakan matriks penilaian risiko. Setelah diidentifikasi, risiko-risiko tersebut akan dilakukan penilaian untuk mengetahui seberapa besar risiko yang terjadi dalam proyek Pembangunan Gedung Parkir tersebut. Dari penelitian ini diperoleh Secara keseluruhan teridentifikasi total sebanyak 29 risiko yang masing-masing terdapat 3 risiko (10%) dari pekerjaan persiapan, 2 risiko (7%) dari pekerjaan tanah, 8 risiko (28%) dari pekerjaan pondasi, 2 risiko (7%) dari pekerjaan struktur, 3 risiko (10%) dari pekerjaan atap & kanopi, 2 risiko (7%) dari pekerjaan clading, 3 risiko (10%) dari pekerjaan tangga rangka baja, 3 risiko (10%) dari pekerjaan lantai, 3 risiko (10%) dari pekerjaan pengecatan. Tingkat penilaian risiko didapat low risk berjumlah 15 risiko (52%) dan Medium risk berjumlah 7 risiko (24%) dan high risk berjumlah 7 risiko (24%). Penerimaan risiko didapat katagori yaitu negligible (sepenuhnya dapat diterima) berjumlah 8 risiko (28%), acceptable (dapat diterima) adalah 7 risiko (24%), undesireable (tidak diharapkan) berjumlah 11 risiko (38%), dan unacceptable (Tidak dapat diterima) berjumlah 3 risiko (10%),. Memberikan pengendalian terhadap resiko K3 yang terjadi pada proyek pembangunan gedung parkir dengan menggunakan Alat Pelindung Diri (APD) yang lengkap.

Abstract

Damage to the road pavement, such as cracking, deformation, and pothole formation, remains common due to increasing traffic loads and environmental influences. One option for enhancing performance of asphalt mixtures is to utilize waste wood charcoal powder as an additive in combinations of Asphalt Concrete-Wearing Course (AC-WC). The objective of this research intended to investigate the effects of employing of wood charcoal powder on the AC-WC mixes' Marshall characteristics and to ascertain the ideal content that meets the specifications of the 2018 Bina Marga Specifications. This research employed a laboratory experimental method by incorporating wood charcoal powder at varying contents of 0%, 2%, 4%, and 6% of the weight of the filler. Features of a combination were evaluated using the Marshall test, with parameters including Void in Mix (VIM), stability, flow, and Marshall Quotient (MQ). The findings demonstrated that the inclusion of wood charcoal powder affected the attributes of the AC-WC mixture. The best performance was obtained at a wood charcoal powder content of 2%, with a stability score of 1,358.5 kg, VIM of 4.16%, flow of 3.64 mm, and Marshall Quotient (MQ) of 382.74 kg/mm. This variation was the only mixture that satisfied all the prerequisites listed the Bina Marga Specifications for 2018 Therefore, a wood charcoal powder content of 2% can be recommended as the ideal content for AC-WC mixtures.

Abstract

This community service program focuses on the development of sustainable "Sungai Space" tourism in Yamansari Village, Tegal. While the village possesses significant natural potential, it faces multidimensional constraints. The main problems include limited supporting infrastructure, low knowledge of modern tourism management, minimal English language skills, restricted utilization of information technology, and a weak understanding of the local economy. The program aims to empower the community through a multidisciplinary approach that integrates infrastructure improvement, English language training, digital technology utilization, and strengthening the creative economy. The method used is Participatory Action Research (PAR), actively involving the community in every stage, from planning and implementation to evaluation. The program was implemented over four months, involving 25 participants from various community elements. Intensive training was provided in English for tourism, digital marketing, business management, and promotional website creation. Data was collected through in-depth interviews, FGDs, participatory observation, questionnaires, and documentation. The program's results show a significant improvement in English communication skills, digital competencies, and understanding of sustainable tourism management. The community successfully developed a website design and promotional social media, implemented an online booking system, and increased participation in the planning and maintenance of infrastructure. The PAR approach proved effective in creating contextual and sustainable solutions by fostering a sense of ownership and collective responsibility. This program has successfully laid a strong foundation for transforming Yamansari Village into a professional and competitive community-based tourist destination. Program sustainability is recommended through continuous training and the development of strategic partnerships with external parties for funding, technology transfer, and market expansion.
