Abstract

Indonesia memiliki iklim tropis lembap, yang menyebabkan suhu udara relatif tinggi dan kecepatan angin cenderung rendah. Kondisi ini berdampak pada kurang optimalnya tingkat kenyamanan termal di dalam masjid. Kenyamanan ruang sangat berpengaruh terhadap kesehatan, kesejahteraan, dan produktivitas individu. Penelitian ini bertujuan untuk menganalisis tingkat kenyamanan termal di dalam Masjid Agung Tuban yang berlokasi di Kabupaten Tuban serta mengevaluasi potensi perbaikan melalui simulasi modifikasi menggunakan Software Ecotect Analysis. Metode yang digunakan dalam penelitian ini mencakup pengukuran langsung suhu dan kelembapan udara di lokasi. Selanjutnya, dilakukan modifikasi terhadap material dinding dan sistem ventilasi menggunakan Software Ecotect Analysis untuk menilai efektivitas perubahan tersebut dalam meningkatkan kenyamanan termal. Hasil penelitian menunjukkan bahwa kondisi awal masjid belum sepenuhnya memenuhi standar kenyamanan termal. Modifikasi dilakukan dengan menerapkan dua jenis material dinding alternatif, yaitu Timber Clad Masonry (dinding batu bata berplaster dengan lapisan marmer) dan Concrete Block Plaster (dinding beton dengan lapisan plester). Hasil simulasi menunjukkan bahwa penggunaan Timber Clad Masonry menghasilkan nilai Mean Radiant Temperature (MRT) sebesar 25,79°C. Selain itu, uji Predicted Percentage Dissatisfaction (PPD) menunjukkan tingkat kepuasan termal sebesar 94,52%, yang berarti mayoritas penghuni merasa nyaman dengan kondisi tersebut. Nilai solar gains dalam ruangan tercatat sebesar 87,25 watt, yang menunjukkan bahwa beban panas akibat radiasi matahari masih berada dalam batas yang memberikan sensasi hangat bagi penghuni.

Abstract

Housing is one of the most popular investment objects in Indonesia. According to the Residential Property Price Survey, housing sales were unstable in 2024. Given this condition, a feasibility study is required for housing projects under development in 2024, particularly for subsidized housing types with relatively low prices, which may result in narrow profit margins. This study conducted a feasibility analysis of the Ababil Land Babat Lamongan housing project, specifically for the 30/60 type unit. This research aims to gather information on the profit margin achieved by the company and the overall investment feasibility of the project, providing valuable considerations for companies or developers in their decision-making processes. The method used in this study is a financial aspect approach, including Net Present Value (NPV), Internal Rate of Return (IRR), and Benefit-Cost Ratio (BCR). The results show that the project yields NPV = IDR 115,222,182.95 > 0, IRR = 7.65% > MARR = 6%, and BCR = 1.031 > 1. Therefore, it can be concluded that the Ababil Land Babat Lamongan housing investment project is financially feasible.

Abstract

Human resources are very important in the work environment, especially in the construction sector. Without a qualified and productive workforce, the project results will not be satisfactory. This research aims to observe the productivity of workers while constructing the pedestrian in front of the Surajaya Stadium in Lamongan, focusing on rebar work, formwork installation, and concreting using the time study method. The initial stage involves analyzing the project and collecting data that will be used as material for observing labor productivity. The productivity for foundation rebar work is recorded at 134.86 kg/person/day, and for column rebar work at 96.84 kg/person/day. The productivity value for formwork also varies, reaching 351.82 m²/person/day for slab formwork work.. Casting work has varying productivity, for example 9.10 m3/person/day for foundation casting. Several factors that affect productivity are the lack of worker skills, hot weather, and obstacles at the project site. The productivity of rebar work, formwork installation, and casting in this project is low due to the lack of worker skills, hot weather causing fatigue, and access barriers. To improve efficiency, training for workers, scheduling work hours, and managing the surrounding environment are necessary.

Abstract

In a building construction project, of course, there are many methods used to schedule a job as well as the cost budget. The purpose of this research is to determine the results of time and cost analysis on the Satnarkoba Police Lamongan Building Construction project. This research uses Critical Path Method (CPM) and Project Evaluation and Review Technique (PERT) with the help of Ms Word 2010 application program to analyze cost and time management. From the results of the analysis, a Network Diagram was found in which there was a series of critical work. Cost analysis is obtained by processing RAB and AHSP data. From this data, the volume, coefficient and wages of workers are obtained as a reference for processing workers' wage data. Based on the results of the analysis found, the critical trajectory, namely with work codes A, E, D, C, G, J, K, N, AF, and AE on a project that lasts for 180 days, gets an acceleration result of 144 days, so the chances of the project can be completed within 144 + 36 = 180 days, with a probability of 4.02%. Based on the results obtained, the average level of probability is greater than 4.02%, this is included in the very high category. In terms of costs incurred from each development, it shows optimal cost efficiency.

Abstract

The Blimbing Paciran Market is a bustling economic activity center, but the available parking facilities are still limited and poorly organized. This causes parking irregularities and congestion around the market area. The main problem raised in this study is the suboptimal capacity of the parking area to accommodate the increasing number of vehicles, especially bemo vehicles. This study aims to evaluate the parking area at Blimbing Market, Paciran, in order to determine the optimal capacity for two-wheeled, three-wheeled, and four-wheeled vehicles. The research location experiences high market activity, yet the limited parking facilities often lead to disorganized parking and congestion. The research methods employed in this study are quantitative and qualitative approaches based on statistical analysis. The results of the study showed that over a 7-day observation period, the average accumulation per day was 37 motorcycles, 16 bemos (three-wheeled vehicles), and 6 cars. The average parking duration was 26 minutes for motorcycles, 29 minutes for bemos, and 29 minutes for cars. The average parking volume was recorded at 183 motorcycles, 40 bemos, and 23 cars. The parking index indicated average values of 38.99% for motorcycles, 129.76% for bemos, and 58.44% for cars. The average parking turnover rate was found to be 1.90 for motorcycles, 3.31 for bemos, and 2.08 for cars.
