Abstract

The development of the construction industry in Indonesia is progressing rapidly, as evidenced by the increasing number of buildings, bridges, roads, and other structures built to meet the needs of the community. In 2022, the population of Banyuasin reached 839,401 people, with 89.23% owning their own homes, 1.81% renting, 7.00% living rent-free, and the remaining 1.96% falling into other categories. The Permen PUPR 2023 method is a cost calculation approach that includes components such as labor, materials, and equipment to determine unit prices for specific types of work. Meanwhile, the real method involves calculating coefficients based on manual calculations of the quantities of materials and wages used, adjusted to the specific work being carried out. The aim of this research is to determine the total cost values calculated using both methods—Permen PUPR 2023 and the real method—and to compare the differences between these total costs in the construction of the Prita Residence 2 subsidized housing project. Cost estimation was conducted based on the building volume calculated from the project drawings. Based on data processing, the Permen PUPR 2023 method resulted in a cost of Rp. 137,874,758, while the real method yielded a cost of Rp. 97,316,225, with a percentage difference of 29.41%.

Abstract

Roads are the primary means of transportation that are essential to support mobility and the distribution of goods and people. As urbanization develops, the increasing vehicle load results in road damage. To address this issue, one potential solution is to modify asphalt using polymer materials such as natural rubber with vulcanized latex. Vulcanized latex, an Indonesian local product, can be used as an additive in asphalt mixtures; however, its use as a main substitute is still limited and primarily supported by empirical and mechanical testing.. The results indicate that mixtures with 7% and 9% vulcanized latex show adequate resistance to soaking, with stability values meeting standards. The inclusion of vulcanized latex at these levels makes the asphalt harder and less elastic, leading to faster fatigue failure, although still within acceptable limits. The use of this material can enhance water resistance but has a negative impact on fatigue life. Therefore, field application must consider a balance between these two aspects to ensure the material's performance remains optimal.

Abstract

This Community Service Program aims to enhance the awareness, knowledge, and practical skills of teachers and students at SD Negeri 2 Palembang in carrying out independent waste management. The main issue identified was the lack of awareness and discipline in sorting organic and inorganic waste, which contributes to environmental pollution and poor hygiene within the school area. The program was implemented through lectures, interactive discussions, and hands-on training involving the use of separate bins for different waste types. The results demonstrated a remarkable improvement in waste management understanding and behavior. Teachers and students have developed new habits of waste sorting before disposal, resulting in a cleaner, healthier, and more pleasant school environment. Additionally, the activity inspired creativity in transforming inorganic waste into useful and economically valuable crafts that can be reused. Overall, this program fostered environmental awareness, strengthened community participation, and encouraged sustainable waste management practices as part of daily school culture.

Abstract

ABSTRAK Kebutuhan sehari-hari air bersih sebagai air minum bagi makhluk hidup sangatlah penting, dan perlu suatu analisis jaringan perpipaan untuk mencukupinya. Analisis jaringan perpipaan sangat komplek dan perhitungannya harus akurat. Sistem jaringan distribusi untuk air minum tentunya penggunaan pipa adalah yang utama, dimana perlu diperhatikan faktor kehilangan tinggi tekanan (headloss). Dan perlu diperhatikan debit dan tekanan yang terjadi, karena semakin besar debit dan kehilangan tinggi tekanan pipa, maka akan berdampak pada distribusi air yang tidak lancar. Kehilangan suatu energi adalah faktor yang berpengaruh terhadap kapasitas pipa sebagai sarana distribusi air, karena debit aliran air akan berkurang. Kehilangan energi disebabkan oleh koefisien gesek pada pipa, perubahan penampang penampang yang ada pada pipa, dan belokan pipa di sepanjang pipa yang digunakan dan panjang pipa juga dapat mempengaruhi kehilangan energi pada pipa. Pada tahun 2019 untuk wilayah pengaliran Booster Kenten pada jaringan pipa distribusi air bersihnya mengalami kehilangan tinggi tekan (hgs), dan yang terbesar pada pipa blok 5 yaitu 1,82 atm, sementara pipa blok 12 yang terkecil yaitu 0,01 atm dengan kehilangan tinggi tekan rata-rata 0,33 atm
