Abstract

Concrete has a weakness against tensile forces. One way to improveconcrete's weakness in tensile strength is by adding fiber to the concrete mix which iscalled fiber concrete. This research was to determine the compressive strength andsplit tensile strength of normal concrete with the addition of coconut fiber aged 7days, 14 days, and 28 days. The percentage of additional coconut fiber fiber is 0.5%;2.5%; 4.5%; 6.5%; and 8.5% of the total volume of concrete. Testing the compressivestrength and split tensile strength of concrete used cylindrical samples with adiameter of 10 cm and a height of 20 cm. The fiber used is coconut fiber with a lengthof 30 mm. The compressive strength value of concrete without the addition of fiber at28 days was 31.33 MPa, while concrete with the addition of 0.5%; 2.5%; 4.5%; 6.5%;and 8.5% coconut fiber obtained compressive strength values of 33.05 MParespectively; 33.72 MPa; 24.46 MPa; 16.47 MPa; and 9.23 MPa. The split tensilestrength value of concrete without the addition of fiber at 28 days was 2.835 MPa,while concrete with the addition of 0.5%; 2.5%; 4.5%; 6.5%; and 8.5% coconut fiberobtained split tensile strength values of 3.497 MPa respectively; 3,754 MPa; 4,029MPa; 3,345 MPa; and 3.039 MPa, while the maximum compressive strength valueoccurs in the 2.5% variation concrete with the addition of coconut fiber, namely33.05 MPa, while the maximum split tensile strength value occurs in the 4.5%variation concrete with the addition of coconut fiber fiber, namely 4,029 MPa. Theresults ofthe split tensile strength equation based on the compressive strength valueof concrete at a percentage of 0% were 0.507√f'c, while in concrete the addition ofcoconut fiber was at 0.5%; 2.5%; 4.5%; 6.5%; and 8.5% respectively amounted to0.608√f'c; 0.646√f'c; 0.815√f'c 0.824√f'c 1.0004√f'c.

Abstract

The demand for ceilings in Indonesia continues to rise in line with large-scale infrastructure renovations aimed at supporting domestic economic growth post-pandemic. Ceilings serve a vital function as heat absorbers, ensuring rooms do not become overly warm. On another note, the utilization of waste in Indonesia remains considerably low, leading to environmental pollution and disruptions to the ecosystem. Among the waste that can be repurposed for building material innovations are bamboo and sugarcane, the latter being one of the primary ingredients for making sugarcane sugar (Saccharumofficinarum). The objective of this research is to devise an innovative substitute for fiberglass ceiling material that is both cost-effective and eco-friendly. This study encompasses various variations, such as A, B, C, D, and E. The fiber proportions for variation A are 100% glassfiber, B is 60% glass fiber and 40% bamboo fiber, C is 80% glass fiber and20% sugarcane fiber, D is 60% glass fiber, 30% bamboo fiber, and 10% sugarcane fiber, while E is 60% glass fiber, 10% bamboo fiber, and 30% sugarcane fiber. The expected outcome of this research is an innovative, ecofriendly, and more affordable ceiling material substitute. Simultaneously, it aims to take concrete steps to minimize environmental impact. The findings reveal that variation D, with proportions of 60% glass fiber, 30% bamboo fiber, and 10% sugarcane fiber, scored the highest in terms of flexural modulus strength at 38,787 kgf/cm2, a density value of 1.65 gr/cm3, and had a production cost that was IDR 189.00 cheaper compared to variation A or the conventional ceiling.

Abstract

The current Local Government is currently focusing on sustainable infrastructure development to provide quality infrastructure facilities to the community. Responding to this condition, the Local Government really needs clear funding sources and well-targeted infrastructure projects. Public Private Partnerships (PPP) is an infrastructure financing innovation that can be implemented by Local Governments, where one of the investment return schemes is Availability Payment. However, based on PPP Books for 2010-2022, only 1 project was successful (8.3%). Many projects are unsuccessful due to the lack of PPP nodes, clear regulations and support from stakeholders, which is the Local Government Governance itself. This research began by conducting a review of several literatures, then conducting interviews to adapt this governance to the characteristics of local government in Indonesia. Furthermore, the indicators that have been obtained will later become a reference for assessing the readiness of Local Government Governance in implementing the PPP Availability Payment. And the results of the analysis that there are 5 indicators of Local Government Governance readiness in the implementation of the Availability Payment, Government Maturity, Social Policy Framework, Institutional Capacity, Legal & Regulatory Environment, and Project Delivery. Furthermore, the results of the assessment show that the Madiun Regency government is more prepared than the Bandung City government in implementing the Availability Payment PPP project in the Public Street Lighting sector.

Abstract

Paving block is a building material consisting of Portland cement, aggregate, water and additional materials. Paving blocks are used on sidewalks, driveways, parks, parking lots, as well as office and educational complexes. However, cracks and breaks are common, even in everyday use. The solution to increase the durability of paving blocks is to add durian peel ash to the mixture. The use of durian skin ash, apart from strengthening the material, also helps reduce the accumulation of waste in durian cultivation areas such as Gunungpati, where usually the durian skin is only burned, thereby accumulating rubbish which can pollute the environment and threaten health. Durian skin which is rich in silica, cellulose, lignin and low in starch can be used as a substitute for cement in making paving blocks. This research used an experimental method with compressive strength and absorption tests at various percentages of durian skin ash composition, namely 0%, 7%, 9%, 11% and 13%. The compressive strength results at 28 days with the optimum composition were obtained for durian skin ash of 9%, with a compressive strength value of 22.805 MPa and an absorption capacity of 5.030%.

Abstract

residents. Soil that is no longer able to absorb water will result in water accumulation, which then forms puddles known as floods. Insufficient infiltration holes are one of the factors contributing to floods. Biopores can serve as an alternative flood prevention method, as they facilitate water absorption into the soil while also being conducive to compost production. The objective of this research is to design a soil drilling tool for biopores as part of flood prevention efforts. An ultrasonic sensor-based soil drilling tool for biopores offers an innovative solution to address flood-related issues. Ultrasonic sensors are utilized to accurately determine the appropriate depth for creating biopores. This is crucial because biopores created at incorrect depths may not function optimally in channeling water into the soil. Ultrasonic sensors enable precise measurement of soil depth without the need for manual excavation. This allows users of the tool to identify ideal locations for biopore creation without causing excessive environmental damage to the surrounding area.

Abstract

Safety road are closely related to geometric design, which includes road function, speed design, superelevation, and alignment. This paper is a geometric study to realize a safety road on Sumpiuh Ring Road, Banyumas Regency, Central Java. The locus of this research is the PI-2 and PI-3 bends located at STA. 22+213 to 22+348 which are two opposing bends that are close to each other. Measurement of existing shows that the transverse slope of the road cross-section at the peak of the PI-2 bend is 2.00% while at PI-3 it is 0.70%. With a speed of 60 km/hour, the driver will have difficulty controlling his vehicle due to centrifugal force. Such conditions make this location prone to accidents. From the analysis results, a transverse slope of 7.75% is required for PI-2, and 6.45% for PI-3. Construction adjustments need to be made to meet the needs of this superelevation design. The form of mitigation that can be done is by adding signs and road facilities such as guardrails, traffic signs such as chevron signs, speed reduction signs, rumble strips, and speed humps. This is intended to reduce the level of accidents at the location and reduce the fatalities.

Abstract

Bakauheni-Terbanggi Besar Toll Road is the main transportation route connecting to South Lampung, Bandar Lampung, Pesawaran, and Central Lampung. Although the location of the Bakauheni-Terbanggi Besar Toll Road is quite strategic, based on the business plan document and the recapitulation of the Bakauheni-Terbanggi Besar Toll Road LHR has a 2021 LHR plan of 20,295 vehicles / day, while the realization LHR is only 11,674 vehicles / day. The traffic situation on the toll road that is not as planned is suspected to be caused by a mismatch of tariffs with the ability and willingness to pay the community, and the current tariff is ±850 / km (category 1 vehicles). Therefore, it is necessary to analyze the adjustment of toll rates with the financial condition of toll road users. In this study, the method used is the calculation of Ability to Pay (ATP) and Willingness to Pay (WTP). The data collection was carried out by distributing questionnaires to 150 respondents. Based on the results of the analysis, the ATP rate of Rp 628 / Km and the WTP rate of Rp 600 / Km. Based on the ATP and WTP relationship graph, the ideal rate for group one vehicles is Rp 626,28 / Km with the percentage of respondents who can afford and are willing to pay at 85,1%.
