Abstract

Indonesia’s road infrastructure requires 1.2 million tons of asphalt annually, but Pertamina can only supply 600,000 tons. This deficit compels the government and related stakeholders to seek alternatives to meet national asphalt needs and maintain road quality. This study aims to analyze the effects of adding Asbuton LGA 50/30 to Asphalt Concrete Wearing Course (AC-WC) with an innovative use of styrofoam waste. Experimental research was conducted to evaluate Marshall characteristics, including VMA (Void in Mineral Aggregate), VIM (Void in Mix), stability, VFA (Void Filled with Asphalt), and Marshall Quotient (MQ). Five styrofoam waste mix variations were tested at 2%, 4%, 6%, 8%, and 10% levels. For the 8% Asbuton mix, the highest stability was observed with 10% styrofoam, yielding a stability value of 2032.16 kg, VMA of 16.63%, VFA of 78.28%, VIM of 3.61%, flow of 2.45 mm, and MQ of 830.33 kg/mm. For the 9% Asbuton mix, the highest stability was achieved with 2% styrofoam, resulting in a stability value of 1882.35 kg, VMA of 16.21%, VFA of 80.17%, VIM of 3.24%, flow of 2.57 mm, and MQ of 735.72 kg/mm. The 10% and 2% styrofoam variations proved to be the most effective for AC-WC asphalt mixtures, as their Marshall values met the 2018 Bina Marga General Specifications, indicating that these styrofoam waste additions are optimal for AC-WC asphalt mixtures.

Abstract

The south Pacitan district's coastal area in Indonesia has become a tourist place because of the more beach with captivating coral. However, that area's natural resources have not altered the function of construction material. Many research uses the coral reef to admixture concrete material in other countries that affect compressive strength. In this research, the coral reef from Pacitan modified the original dimension of fine aggregate for material substitute o to become the coral sand of fine aggregate with the different material characteristics from other coastal areas. The sample variation was created into four categories, and five samples in every category were concrete without coral sand or 0% coral sand content, 75% with coral sand, 85% with coral sand, and 90% with coral sand. All samples were tested when the concrete age was achieved 28 days after immersing for 14 days, so the concrete was in the maximum setting time condition. The result shows that the percentage effectiveness of coral sand content is 75% as fine aggregate substitution by increasing the compressive is 15.24%, however higher coral sand content causes the decrease until 27.12% to concrete without coral sand, this result can effect by the material characteristic of coral sand when changing the dimension

Abstract

IDM adalah alat ukur yang dikembangkan oleh Kementerian Desa, Pembangunan Daerah Tertinggal, dan Transmigrasi (Kemendes PDTT) untuk memotret kondisi objektif desa berdasarkan data yang dikumpulkan dari pemerintah desa. Klasifikasim menurut IDM menjadi lima yaitu : Desa sangat tertinggal, Tertinggal, Berkembang, Maju, dan Mandiri. Di Kabupaten Wonogiri Terdapat 251 Desa, salah satunya adalah pada Desa Purwosari, skor IDM: 0.7598 (Desa Maju). Pengabdian ini didasarkan pada permasalahan kerentanan indeks ekologi dan lingkungan desa-desa di Wonogiri dari data status penilaian IDM, dengan menggunakan tiga aspek penilaian yakni; penilaian terhadap Indeks Ketahanan Sosial (IKS: 0.806), Indeks Ketahanan Ekonomi (IKE: 0.667) dan Indeks Ketahanan Lingkungan (IKL: 0.533), melalui pendekatan partisipatif rural appraisal (PRA). Model pemberdayaan masyarakat yang ditawarkan berupa peningkatan kapasitas masyarakat dengan luaran, 1) Produk perencanaan: masterplan lingkungan permukiman berkelanjutan melalui penyediaan Ruang Terbuka Hijau (RTH) per-Kapita, 2) Produk hukum: penyusunan Perdes pengelolaan infrastruktur desa ramahlingkungan.

Abstract

Plastic has become an inseparable material from human daily life. Plastic waste has properties that are very difficult to decompose which has a negative impact on the environment, which has become a serious problem in the global context. One alternative for dealing with plastic waste that can be applied in the world of civil engineering is by reusing plastic waste as aggregate in making bricks. This research aims to determine the effect of using polyethylene terephthalate (PET) plastic waste as a partial substitute for fine aggregate in making bricks on compressive strength and water absorption. In this research, variations in the use of PET plastic waste were 0%, 5%, 10% and 15%, referring to SNI-03-0349-1989. Compressive strength tests have respective values ​​of 7.5 Mpa, 6.3 Mpa, 6.2 Mpa, and 5.7 Mpa. In the water absorption test, the respective values ​​were 4%, 4.3%, 4.7% and 7%. Adding too much plastic to the brick mixture proved to be ineffective on the compressive strength of the brick. This means that the mortar and PET plastic on the bricks cannot interlock with each other.

Abstract

A number of studies and trials on concrete have been conducted to improve concrete quality and address common issues in the construction industry, such as project deadlines. Efforts to enhance concrete quality include modifications to achieve high concrete strength at 7 days using chemical admixtures. This research aims to analyze the effect of using MR 73 admixture on the flexural strength of concrete at the ages of 7 and 28 days. The research method employed is experimental quantitative. The results indicate that concrete with MR 73 admixture at a 0.4% dosage achieved an average flexural strength of 43.5042 kg/cm² at 7 days, compared to normal concrete with 35.34 kg/cm² at the same age. At 28 days, concrete with MR 73 admixture at a 0.4% dosage reached an average flexural strength of 49.97 kg/cm², compared to normal concrete with 45.54 kg/cm². The MR 73 admixture proved to increase the flexural strength of concrete by 23% at 7 days and 10% at 28 days compared to normal concrete
