Abstract

Porous Concrete is a type of Concrete that has a cavity in its structure that allows liquid to flow through the cavity. This study aims to determine the effect of adding Master Ease 5010 admixture on the compressive strength and absorption capacity of porous Concrete. The method used in this research is an experimental method by making different tests in the laboratory. The sample used is 10 x 20 cm with a concrete age of 28 days. The tests carried out include compressive strength testing and absorption testing. The absorption test used the falling head method based on the ACI 522R. The results of the normal compressive strength test = 0.28 Mpa, the addition of Master Ease 5010 3% = 0.31 Mpa, and the addition of Master Ease 5010 5% = 0.416 Mpa while testing the absorption of Normal Porous Concrete = 1.406 mm/s, addition of Master Ease 5010 3% = 1,946 mm/s, addition of Master Ease 5010 5% = 2.196 mm/s. From these results, it can be seen that the addition of Master Ease 5010 is able to increase the compressive strength and absorption value of porous Concrete.

Abstract

In the construction industry, one of the materials that are often used is brick. Bricks are very much needed including as a wall barrier in residential buildings with non-structural functions. The need for the willingness of bricks according to standards and affordable prices is also increasing, which makes brick production very desirable, especially construction actors. But the use of clay as the only material of brick production will provide the results of bricks that are easily cracked. This causes an increasing scarcity of the main material of clay, even more expensive. Therefore, it is necessary to utilize environmentally friendly waste materials to be the right choice in making innovations, one of which is the use of rice husk waste. The methods used are socialization related to the purpose of community service, extension and transfer of materials technology science, training and assistance in brick production, monitoring and evaluation. The location of the activity was carried out in Gambirejo Village, Tanjunganom Subdistrict, Nganjuk Regency which is a village famous for its red brick industry in Nganjuk Regency. This mentoring activity is in the form of training and extension to improve the knowledge and skills of partners so that the production of the resulting bricks becomes more quality with more efficient production costs.

Abstract

Abstract. Red brick is a building material widely used in Indonesia as a non-structural separator wall of a building. Soil is the main material in the production of red bricks. The soil used for the main material of red brick is sandy clay soil. The advantage of red brick is that it is resistant to hot weather or fire because it has undergone the combustion process. However, new innovations are necessary for the red brick manufacturing process due to the reduced soil.  The innovation carried out in this study was adding the main material with fly ash and rice husk ash. The purpose of this study was to obtain red brick mixture fly ash and rice husks with increased compressive strength than normal red bricks.  The research method used is an experimental method with the addition of fly ash and rice husk ash by 4%, 8%, and 12% of the soil weight.  The results obtained from this study are red bricks with fly ash and rice husk ash produced the highest value in the fly ash mixture of 12% (in sample D2) content of 75.07 Kgf / cm² so as to improve the quality of conventional red bricks.

Abstract

Pembangunan gedung Universitas Kadiri terus berkembang pesat. Kolom beton bertulang merupakan pilihan yang paling umum digunakan dalam pembangunan gedung-gedung tinggi. Namun, pekerjaan kolom membutuhkan tenaga kerja yang cukup banyak. Tujuan penelitian ini adalah untuk menganalisis pengaruh penambahan tenaga kerja terhadap produktivitas dan efisiensi pekerjaan kolom. Penelitian ini menggunakan metode kuantitatif. Data waktu kerja yang dibutuhkan untuk menyelesaikan setiap aktivitas kerja kolom diperoleh dari observasi menggunakan alat stopwatch. Data tersebut kemudian digunakan untuk menghitung waktu normal, allowance, waktu standar, output standar, produktivitas, dan efisiensi. Penambahan tenaga kerja dari 6 menjadi 7 dapat meningkatkan produktivitas sebesar 3,29% dan efisiensi sebesar 6,54%. Peningkatan produktivitas relatif kecil dibandingkan dengan peningkatan efisiensinya. Temuan ini memberikan bukti empiris bahwa penambahan tenaga kerja dapat meningkatkan efisiensi pekerjaan kolom.

Abstract

Transformasi digital dalam industri konstruksi menuntut peningkatan efisiensi dan akurasi, terutama dalam pengelolaan material seperti besi tulangan yang memiliki kontribusi besar terhadap struktur dan biaya proyek. Building Information Modelling (BIM) hadir sebagai solusi inovatif untuk menjawab tantangan ini. Namun, adopsi BIM dalam proyek skala kecil-menengah, khususnya di daerah seperti Tulungagung, masih sangat terbatas. Kegiatan pengabdian ini bertujuan untuk mensosialisasikan dan melatih penggunaan teknologi BIM kepada pelaku konstruksi lokal, dengan fokus pada perencanaan kebutuhan tulangan besi untuk membangun kolom dan balok. Pelatihan ini melibatkan pemodelan struktur 3D menggunakan Autodesk Revit serta penerapan metode Bar Bending Schedule (BBS) untuk menghitung volume, waktu, dan efisiensi material. Hasil ini BIM mampu mengurangi potensi pemborosan besi tulangan sebesar 18,7% dan memangkas perkiraan waktu dari 9 jam menjadi 3 jam. Selain peningkatan akurasi perencanaan, peserta menunjukkan antusiasme yang tinggi untuk menerapkan BIM dalam proyeknya. Temuan ini membuktikan bahwa pelatihan BIM berbasis studi kasus lokal efektif dalam meningkatkan efisiensi proyek dan kapasitas sumber daya manusia di wilayah tersebut. Replikasi kegiatan dan dukungan infrastruktur digital direkomendasikan untuk memperluas dampak positif teknologi BIM di sektor konstruksi nasional. Kegiatan ini berdampak positif dalam membangun kesadaran akan pentingnya digitalisasi perencanaan konstruksi dan membuka peluang untuk adopsi BIM yang lebih luas di tingkat lokal. Disarankan agar ada dukungan lebih lanjut berupa pelatihan tingkat menengah dan penyediaan akses perangkat lunak BIM sehingga dampak dari kegiatan tersebut dapat berkelanjutan.

Abstract

A This study analyzes the implementation of green roofs integrated with lean construction in the Public Service Building of Kediri Regency, focusing on construction efficiency and environmental impact. Green roofs were selected as an innovative solution to mitigate urban heat island effects, enhance rainwater absorption, and support biodiversity, while lean construction was applied to minimize material waste, time, and labor. The research methods included literature reviews, primary data collection through questionnaires (100 respondents), and data analysis using SPSS and Value Stream Mapping (VSM). The results indicate that integrating these two concepts can reduce the building's microclimate temperature by 10–15% and shorten construction time by up to 25% compared to conventional methods. Key supporting factors include the availability of local materials and policy support, while the main challenges are high initial costs and multidisciplinary coordination. The study provides recommendations for tropical climate-adapted green roof designs and lean construction strategies to improve project efficiency and reduce environmental impact, aligning with the Sustainable Development Goals (SDGs), particularly Goal 11 (Sustainable Cities) and Goal 12 (Responsible Consumption and Production).

Abstract

Urban development is often accompanied by traffic challenges, particularly the increasing volume of vehicles that is not commensurate with the capacity of road infrastructure. This study aims to evaluate the effect of spatial heterogeneity of vehicle volume and type on vehicle speed at four main intersections in Kediri City: Alun-Alun, Semampir, Bandar Alim, and Kawi. A quantitative approach was used through direct observation, floating car method, and linear regression analysis and ANOVA. The results show that intersections with high vehicle volume tend to have lower speeds, especially when dominated by heavy vehicles. Alun-Alun intersection has the highest R-Square value for vehicle volume (0.847), while Bandar Alim intersection recorded the highest R-Square for vehicle speed (82%). T-test and ANOVA indicate a significant effect of vehicle direction and type on speed, especially at Semampir and Bandar Alim. These findings demonstrate the importance of integrating volume and speed in traffic management, as well as the need for a data-driven and spatial approach in developing intelligent transportation systems. Therefore, it is necessary to discuss further in the objectives and body of the research regarding the causal relationship between vehicle volume, vehicle type composition, travel direction, and spatial variations between intersections, so that the research results can provide a stronger scientific basis for adaptive traffic management policies to the specific conditions of each intersection.
