Abstract

Mortar mixture is an important element in civil/construction work. As a binding agent, mortar mixtures are widely used in various types of work with different strength levels according to their needs. Many sand raw materials are often used but do not meet the material requirements, either grain gradation or other requirements. In this research, a compressive strength test was carried out using fine sand with the addition of stone ash, to test how much strength was achieved with varying percentages of additional stone ash. The manufacture of test specimens for this mortar mixture refers to SNI 03-6882-2002. Testing was carried out at 7 days, 14 days and 28 days. With additional variations of 0%, 20%, 40% and 60% stone ash. The results of this research are mortar mixtures with the addition of 20% stone ash will increase the compressive strength from 4.74 MPa without the addition of stone ash to 7.13 MPa, tending to decrease at an additional 40% the compressive strength is 6.96 MPa and at an additional 60% the strength is obtained. press 5.74Mpa. The simple regression equation for the relationship between the addition of the percentage of stone ash (variable x) and the compressive strength value (variable y) is y = -22.578x2 + 14.97x + 4.8122 with the coefficient of determination R2 = 0.97 (very strong).

Abstract

Program Pengabdian kepada Masyarakat (PKM) berbasis Kuliah Kerja Nyata (KKN) di Desa Sindang Kasih dilaksanakan sebagai upaya pemberdayaan masyarakat melalui pendekatan terpadu pada aspek infrastruktur, sosial kemasyarakatan, dan ekonomi lokal. Kegiatan ini dilatarbelakangi oleh masih terbatasnya kualitas fasilitas publik, rendahnya partisipasi sosial terorganisir, serta belum optimalnya pengelolaan dan promosi potensi ekonomi desa, khususnya UMKM. Solusi yang diterapkan bersifat partisipatif dan kolaboratif dengan melibatkan pemerintah desa, masyarakat, serta mahasiswa KKN sebagai fasilitator. Pada aspek infrastruktur, kegiatan difokuskan pada penataan lingkungan Balai Desa, pembuatan peta wilayah desa, penyusunan denah sekolah, serta penyediaan plang nama aparatur desa sebagai sarana keterbukaan informasi publik. Pada aspek sosial, pendampingan dilakukan melalui kegiatan gotong royong, Jumat bersih, pelayanan posyandu, dan partisipasi dalam kegiatan keagamaan untuk memperkuat kohesi sosial dan kesadaran kolektif masyarakat. Sementara itu, pada aspek ekonomi, dilakukan pendampingan promosi UMKM melalui pemasangan banner di lokasi strategis guna meningkatkan visibilitas produk lokal. Hasil kegiatan menunjukkan adanya peningkatan kualitas lingkungan desa, partisipasi masyarakat, serta kesadaran terhadap pentingnya pembangunan berbasis kebersamaan dan potensi lokal. Secara integratif, PKM berbasis KKN ini terbukti mampu menjadi katalisator pembangunan desa yang berkelanjutan dan berorientasi pada kebutuhan riil masyarakat

Abstract

This study analyzes the impact of the implementation of pedestrian zones on the level of road services on two road sections, namely Jalan Tabaununggu and Jalan Supu Yusuf. Results Before the pedestrianization, Jalan Tabaununggu had a capacity of 2586 PCU/h per direction with a degree of saturation (Q/C) of 0.49, at Service Level C. After the pedestrian zone was enforced, the capacity decreased to 2674 PCU/h with Q/C of 0.33, which indicates an increase to Service Level B. On the other hand, on Jalan Supu Yusuf, before pedestrianization, the capacity was recorded at 2998 PCU/h per direction with a Q/C of 0.43 (Service Level B). After pedestrianization, the capacity increased to 2676 PCU/h per direction and Q/C decreased to 0.34, so that the service level increased to B. These results show that the implementation of pedestrian zones has a positive impact on the stability and efficiency of traffic flow, especially on Jalan Supu Yusuf-Tabaununggu Kendari City.

Abstract

This study aims to analyze the structural capacity of the existing pavement and to determine the required thickness of flexible pavement overlay on the Kolaka – Rate-rate Road section to adequately serve traffic loads over a 20-year design life. Based on traffic survey results, the Average Daily Traffic (ADT) indicates a dominant contribution from heavy vehicles. The calculation shows a daily Equivalent Standard Axle (ESA) value of 1,322.47 ESA/day, with the largest contribution coming from 3-axle and ≥4-axle trucks. Considering an annual traffic growth rate of 5% and a 20-year design life, the Cumulative Equivalent Standard Axle (CESA) is estimated at approximately 1.60 × 10⁷ ESA. The evaluation of the existing pavement structure yields a Structural Number (SNₑₓ) of 6.96. Based on the relationship between CESA and subgrade bearing capacity (CBR 6%), the required Structural Number (SNᵣ) is determined to be 8.50. The difference between the required SN and the existing SN results in an overlay Structural Number (SNₒᵥ) requirement of 1.54. This value is then converted into the required asphalt overlay thickness using the appropriate layer coefficient

Abstract

This study is entitled “Geometric Evaluation of the Lanosangia–Wantulasi Road Section, North Buton Regency (Sta. 2+600–5+000).” Land transportation plays a strategic role in supporting economic growth; therefore, road geometric design must meet technical standards to ensure safety and comfort. This study addresses the issue that several road segments do not fully comply with geometric standards, particularly in terms of sharp curves and steep gradients. The objective of this research is to evaluate the existing geometric conditions, including horizontal alignment, vertical alignment, and cross-sections, based on the Guidelines for Geometric Design of Roads (PDGJ 2021) issued by the Directorate General of Bina Marga. A quantitative descriptive method was applied by comparing field data with applicable standards. Primary data were collected through field surveys using Geodetic/RTK measurements, while secondary data were obtained from related agencies. Data analysis was conducted using Digital Application Road to model alignments and calculate geometric parameters. The results show that the horizontal alignment consists of Spiral–Circle–Spiral (SCS) and Full Circle (FC) curves. Several vertical alignment segments have gradients exceeding 10%, although the overall terrain is classified as flat. The Stopping Sight Distance (SSD) meets safety standards. However, not all geometric elements comply with PDGJ 2021. This study provides recommendations to optimize road design qualit.

Abstract

Ahmad Yani Street in Kendari City is one of the main road segments with high traffic activity, especially during peak hours. This study aims to analyze the road performance by examining traffic volume, side friction, speed, degree of saturation, and level of service (LOS). Data were collected through field surveys for three days during morning, afternoon, and evening peak hours. The observation segment spans 200 meters, from the front of SMP Negeri 4 Kendari to the front of Ittifaqul Jama’ah Mosque. The analysis results indicate that traffic volume is higher on Segment B, influenced by the presence of a gas station and school, while Segment A experiences smoother flow due to the presence of only a mosque. The highest side friction is also found on Segment B. The free-flow speed (FFS) is recorded at 49 km/h on Segment A and 47 km/h on Segment B. The actual travel speed (VT) is 35 km/h for Segment A and 28 km/h for Segment B. The degree of saturation is 0.70 on Segment A and 0.80 on Segment B. Based on these values, the level of service for Segment A falls into category C, while Segment B is in category D. These findings indicate that Segment B's performance requires further attention to improve traffic flow.
