Abstract

Based on data from the Central Statistics Agency (BPS), the population of Cilacap has increased by 300,282 people over the past five years. With rapid population growth, the need for housing is becoming increasingly difficult to meet. The Ministry of Public Works and Public Housing (PUPR) is committed to building public housing as a solution to this problem. However, to ensure that these buildings are livable and sustainable, it is important to conduct a comprehensive cost analysis. In construction projects, life cycle cost analysis is one of the efforts to prepare for the need to understand that costs are not limited to the construction phase. Construction projects often only consider initial costs, which can lead to errors in long-term financial planning. Life Cycle Cost Analysis helps in long-term planning, enabling decision-makers to consider all aspects of costs that will arise throughout the building's lifespan. This not only improves budget efficiency but also ensures that residents receive adequate housing facilities. Therefore, it is necessary to conduct research on the economic value analysis of a building, specifically in the form of life cycle cost planning, for a low-cost apartment building with a 25-year lifespan. This analysis should encompass initial costs, operational costs, and maintenance and replacement costs. This research is quantitative. The method used is life cycle cost. Data collection methods include field observations and interviews. The research results indicate that the life cycle cost (LCC) planned for a 25-year lifespan amounts to Rp 20,486,745,640, comprising initial costs of Rp 13,446,741,389 (54.07%), operational costs of Rp 5,832,349,683 (23.45%), maintenance costs of Rp 1,940,837,459 (7.80%), and replacement costs of Rp 3,649,042,776 (14.67%).

Abstract

Permasalahan akumulasi yang terus meningkat di kawasan perkotaan. Strategi mitigasi banjir konvensional belum sepenuhnya efektif. Genangan hanya dianggap sebagai dampak pasif dari sistem drainase yang gagal. Penelitian ini bertujuan mengkaji strategi mitigasi banjir dapat dirancang secara efektif. Penurunan potensi permukaan melalui pendekatan tata ruang kota. Kajian dilakukan menggunakan metode Systematic Literature Review (SLR) dengan menganalisis 68 artikel ilmiah. Artikel dari basis data Scopus melalui proses identifikasi, skrining, penilaian kelayakan, dan penilaian kualitas. Hasilnya menunjukkan bahwa sebagian besar literatur berfokus pada tema perencanaan spasial dan mitigasi banjir. Pembahasan strategi teknis untuk menurunkan volume atau durasi konsentrasi. Kajian ini menyimpulkan perlunya pendekatan baru yang menjadikan kemiringan sebagai indikator utama. Indikator kemunduran keberhasilan mitigasi banjir. Pendekatan melalui data spasial, zona retensi, dan desain sistem resapan dalam perencanaan tata ruang yang adaptif.

Abstract

The construction industry is an important thing to support the development of a country. In concrete construction, quality, strength, and durability of concrete are the main requirements of all. In urban tropical countries, carbonation is one of the essential factors that affect the durability of concrete, and it may cause corrosion of reinforced steel in concrete. Therefore, high strength self-compacting concrete may be expected as the solution, improved by pozzolanic additions, metakaolin with substitution dosage at 10%; 12,5%; 15%; 17,5%; and 20%. This study purposed to determine the effect of metakaolin and its optimum dosage to improve high strength self-compacting concrete quality on its carbonation rates. This study was done by using experimental methods. It needs a plain cylindrical concrete with 75 mm diameter and 150 mm height, and testing by SNI 03-6468-2000, EFNARC 2002, and SEM-PUPR 25-2015. The carbonation test is done using accelerated laboratory carbonation in Structures and Materials Laboratory, Faculty of Engineering, Universitas Sebelas Maret by soaking the specimens in a 4% carbonate solution for 15 days, 37 days, and 51 days, proceeded by splitting using CTM, and spray it using a 1% phenolphthalein indicator to determine its carbonation depth. Based on the results, metakaolin might improve concrete quality by reducing its carbonation rates by 15% substitution dosage of cement content, with a nominal atmospheric carbonation coefficient 3,71 mm/year½, reduced 44,41% from HSSCC without metakaolin substitution. Metakaolin addition might reduce fresh concrete's workability and fulfill self-compacting concrete requirements specified by EFNARC 2002.

Abstract

Flood, economic and environmental problems in the implementation of sustainable drainage systems in developing countries are very complex. The use of infiltration wells as an alternative method to infiltrate groundwater as one of the low-impact developments. Infiltration wells function to accommodate and absorb water into the soil. The high growth of the population led to an increase in development. Development that has an impact on the reduction of catchment areas, this research aims to approach the low-impact development strategy (LID) in urban areas in developing countries. Sustainable drainage development is still limited to the regional budget. Cost analysis was carried out by hydrological modeling for infiltration well planning. Infiltration wells are chosen as sustainable drainage. Infiltration wells can reduce the risk of flooding and drought. Discharge analysis with the Rational Method. The planning of the dimensional infiltration well was calculated using the Sunjoto formula and the basic design using filitration. The infiltration well model is planned with a depth of 1.7 m and a diameter of 1 m. The cost of making an infiltration well is Rp 2,125,500 for one well. This research is expected to help decision-making in sustainable urban water management. Flood and drought mitigation balancers and costs.
