Abstract

Kawasan Sungai Blorong di Kabupaten Kendal memiliki potensi strategis untuk dikembangkan sebagai kawasan ecotourism berbasis aktivitas air dan rekreasi alam. Penelitian ini bertujuan merancang fasilitas ecotourism serta menganalisis kelayakan ekonomi pengembangannya dari aspek ekonomi teknik. Metode yang digunakan adalah deskriptif kuantitatif. Perencanaan desain fasilitas dilakukan menggunakan perangkat lunak SketchUp untuk memvisualisasikan tata letak kawasan, sarana pendukung, serta infrastruktur utama. Analisis biaya meliputi penyusunan Rencana Anggaran Biaya (RAB) dengan perhitungan variabel biaya yang terdiri atas biaya investasi awal (biaya modal) serta biaya operasional dan pemeliharaan (O&P). Variabel manfaat dianalisis dalam bentuk tangible benefit seperti pendapatan tiket, sewa fasilitas, dan parkir, serta intangible benefit berupa peningkatan kualitas lingkungan dan dampak sosial ekonomi bagi masyarakat sekitar. Evaluasi kelayakan ekonomi menggunakan metode Net Present Value (NPV), Benefit Cost Ratio (BCR), dan Internal Rate of Return (IRR) dengan tingkat suku bunga 5%. Hasil analisis menunjukkan total biaya investasi sebesar Rp 853.962.273,00, nilai NPV sebesar Rp 467.580.053,00, BCR sebesar 1,23, serta IRR sebesar 14,27%. Nilai tersebut mengindikasikan bahwa proyek layak secara ekonomi karena NPV bernilai positif, BCR lebih dari 1, dan IRR melebihi tingkat suku bunga yang digunakan. Analisis sensitivitas menunjukkan proyek tetap layak pada seluruh skenario perubahan variabel utama, dengan kinerja ekonomi tertinggi pada kondisi kenaikan manfaat sebesar 10% dan biaya tetap. Dengan demikian, pengembangan ecotourism Sungai Blorong dinilai prospektif serta berpotensi meningkatkan aktivitas ekonomi masyarakat setempat.

Abstract

Pengembangan fasilitas penunjang non-medis diperlukan untuk meningkatkan fungsi kawasan rumah sakit tanpa mengganggu pelayanan medis utama. Rumah Sakit Hermina Salatiga merencanakan pembangunan fasilitas penunjang berupa bangunan tiga lantai yang difungsikan sebagai parkir semi-basement, minimarket, dan kafe, serta penambahan taman terapi dan booth UMKM. Penelitian ini bertujuan untuk mengembangkan desain fasilitas penunjang serta menganalisis kelayakan ekonomi teknik dari pembangunan yang direncanakan. Metode yang digunakan adalah pendekatan deskriptif kuantitatif melalui analisis kondisi eksisting, perancangan desain bangunan, perhitungan biaya konstruksi dan operasional selama umur bangunan 15 tahun, serta estimasi manfaat baik tangible maupun intangible. Evaluasi kelayakan dilakukan menggunakan parameter Net Present Value (NPV), Benefit Cost Ratio (BCR), dan Internal Rate of Return (IRR), serta dilengkapi dengan analisis Break Even Point (BEP) dan analisis sensitivitas untuk menguji ketahanan proyek terhadap perubahan variabel. Hasil analisis menunjukkan bahwa total biaya investasi sebesar Rp 2.473.361.546,53 dengan total manfaat ekonomi sebesar Rp 12.000.427.500,00. Pada tingkat suku bunga 13%, diperoleh nilai NPV sebesar Rp 482.952.368,08, BCR sebesar 1,12, dan IRR sebesar 17,003%. Titik impas (BEP) tercapai pada tahun ke-9 masa operasional. Analisis sensitivitas menunjukkan bahwa proyek tetap layak pada berbagai skenario perubahan biaya dan manfaat. Dengan demikian, pengembangan fasilitas penunjang Rumah Sakit Hermina Salatiga dinyatakan layak secara ekonomi teknik dan mampu memberikan nilai tambah terhadap kualitas layanan serta keberlanjutan operasional rumah sakit.

Abstract

Subdistrict office buildings, as public service infrastructure, play an important role in supporting government functions at the regional level. However, many office buildings are physically damaged or do not meet administrative requirements. This study aims to evaluate the suitability of district office buildings in Tegal Regency based on technical and administrative aspects in accordance with Ministry of Public Works and Housing Regulation No. 29/PRT/M/2006 and Law No. 28 of 2002 on Building Structures. The study was conducted on seven district offices: Bumijawa, Balapulang, Lebaksiu, Pagerbarang, Adiwerna, Talang, and Kramat. The methods used included a visual survey of structural, architectural, and utility elements with a weighting system (structure 40%, architecture 35%, utilities 25%) as well as an examination of administrative documents such as Land Certificates, KIB, IMB, and SLF. The research results showed that Talang Subdistrict had an average score of 1.41 and was categorized as Suitable. Bumijawa District (1.94), Balapulang District (1.98), and Lebaksiu District (2.01) are classified as Conditionally Feasible. Meanwhile, Pagerbarang District (2.74), Adiwerna District (2.63), and Kramat District (2.77) are categorized as Not Feasible. From an administrative perspective, none of the subdistricts have building permits (IMB) or site clearance certificates (SLF), resulting in an average administrative score of only 2 out of 4 points (50%). This study recommends gradual improvements, prioritizing technical rehabilitation budgets, and expediting the processing of legal documents to enhance the suitability of subdistrict office buildings

Abstract

The selection of contract types for port construction projects is a strategic decision that affects the success of project implementation, particularly in managing risks, costs, and technical complexities. This study aims to analyze the performance of Design and Build contracts in port projects and determine the most suitable contract type using the Analytical Hierarchy Process (AHP) method. This study uses a descriptive quantitative approach with case studies on three port projects, namely the Ex. Semen Tonasa Port Branch Banjarmasin Stacking Field Paving Project, the Batang Multipurpose Terminal Phase I Development, and the Design and Build Revetment and Retaining Wall Dumping 1 Benoa Port. Project performance analysis was conducted based on time deviation and profit percentage against the contract BOQ. Furthermore, the best contract type was determined using the AHP method through the preparation of a decision hierarchy, pairwise comparisons between criteria and alternatives, priority weight calculations, and consistency ratio testing. The results of the study show that all projects experienced time extensions of between 25% and 56%, but still generated positive profits with margins of between 8.69% and 22.79%. AHP analysis with four main criteria of risk level, cost, scale of work, and source of financing shows that the risk level has the highest weight of 0.518 (51.8%). The global priority calculation resulted in the Design and Build contract as the most suitable alternative with a weight of 0.49 (49%), followed by the conventional contract (0.27) and Lump Sum (0.24). This study concludes that for port projects with high complexity and risk, the Design and Build contract is the most effective option because it integrates design and construction into one coordinated responsibility.

Abstract

The increasing demand for clean water at the Faculty of Engineering, Sultan Agung Islamic University (UNISSULA) Semarang requires an alternative and sustainable water source. One effective solution is the implementation of a rainwater harvesting (RWH) system to meet non-domestic water needs such as toilet flushing, plant irrigation, and campus cleaning. This study aims to analyze the potential utilization of rainwater, design an appropriate RWH system, and evaluate its cost efficiency compared to the use of PDAM (regional water supply company) water. This research employed a quantitative approach by collecting primary data, including roof catchment area measurements and existing rainwater drainage conditions, as well as secondary data such as average rainfall, the number of campus users, and PDAM water tariffs. The analysis consisted of calculating the potential harvested rainwater volume, designing the RWH system, estimating installation costs, and comparing operational costs between RWH and PDAM water usage. The results indicate that the potential harvested rainwater volume from the building’s roof is approximately 7,054.5 liters/day, while the average non-domestic water demand is 3,170 liters/day, allowing water needs to be met during the rainy season. The implementation of the RWH system can also reduce water costs by up to 43,6%, equivalent to IDR 87.615.616 over a 20-year period. Therefore, the application of RWH is an effective and sustainable solution for water management within the campus while supporting operational cost efficiency.
