Abstract

Dinding pengisi memberikan pengaruh kekakuan struktur rangka penahan momen. Pengabaian kekakuan dari dinding pengisi tersebut dapat memengaruhi perilaku berupa simpangan antar tingkat. Studi ini dilakukan untuk mengetahui pengaruh kekakuan dinding pengisi, baik dinding yang penuh maupun dinding yang berlubang, pada suatu struktur gedung hotel dengan sistem struktur rangka baja penahan momen. Gedung hotel berlantai empat memiliki fungsi restoran dan lobi pada lantai dasar sehingga pada lantai tersebut tidak terdapat dinding pengisi. Sedangkan sisa tiga lantai di atasnya digunakan sebagai kamar-kamar. Dinding pengisi dimodelkan sebagai elemen shell dan celah antara dinding pengisi dengan struktur rangka dimodel sebagai elemen gap. Perletakan struktur dianggap sebagai sendi dengan asumsi sambungan antara kolom baja dengan kolom pedestal beton bertulang memungkinkan terjadinya putaran sudut. Hasil analisis menunjukkan simpangan antar tingkat pada model yang tidak memperhitungkan kekakuan dinding pengisi (MOF) jauh melebihi simpangan antar tingkat izin, terutama pada lantai dua dan tiga. Sedangkan model yang memperhitungkan kekakuan dinding pengisi (MIF) melebihi simpangan antar tingkat izin hanya pada lantai dua. Kontribusi kekakuan dinding pengisi mengakibatkan simpangan MIF menjadi kurang lebih setengah dari simpangan MOF. Untuk mengatasi permasalahan simpangan antar tingkat, dilakukan perubahan asumsi perletakan menjadi jepit. Perubahan perletakan tersebut sangat signifikan meningkatkan kinerja simpangan antar tingkat, kecuali MOF.

Abstract

As regulated in Law No. 26 of 2007 concerning Spatial Planning, the urban spatial structure is an arrangement of settlement centres and infrastructure networks that support socio-economic activities through hierarchical functional relationships. In Tegal City, one of the crucial infrastructure elements is the road network, especially the North Coast national route, commonly called the Pantura Route. The Pantura Route strategically affects urban mobility and connectivity between regions. Its location in the city centre makes this route an important arterial corridor connecting major cities on Java Island, such as the Jakarta-Tegal-Purwokerto-Yogyakarta-Surabaya route. However, the high intensity of land use for economic, social, and educational activities has caused various problems, such as traffic accidents. In 2018, 59% of accidents occurred along this route, although this route only covers 13% of the total length of roads in Tegal City. Other problems include limited road infrastructure, physical damage to roads, and low road accessibility, which are also supporting factors. Important local-scale activities along the Pantura route, such as schools, health centres, and trade activities, raise concerns regarding the suitability of spatial structures and safety, especially when compared to national Standards (SNI 03-1733-2004). The method used in this study uses primary and secondary surveys and qualitative descriptive analysis, namely content analysis. The results of this study indicate that the deviation of spatial structures that occur in Tegal City is more than 50% seen from the existence of educational facilities (elementary and junior high schools), health facilities (health centres), and markets with a local scale that are not appropriate along the Pantura route. With regional authority within the framework of Law No. 23 of 2014 concerning Regional Autonomy, the city government is expected to be more active in managing spatial planning, especially spatial structures, so that deviations do not occur. This study aims to evaluate the suitability of the spatial structure of Tegal City by evaluating the function of the road network and the scale of service facilities based on urban environmental planning Standards. The findings of this study are expected to support effective and sustainable spatial planning of Tegal City.

Abstract

The Ijen Crater Nature Tourism Park (Ijen Crater TWA) is one of the tourist destinations with the enchanting blue fire that is quite famous in East Java and even internationally. Ijen Crater has a crater lake with a very low pH, making it one of the largest acidic lakes in the world. It also has significant mineral resource potential in the form of sulfur. Not only that, but Ijen Crater is also part of the Ijen UNESCO Global Geopark. The Ijen Crater TWA is administratively located in Bondowoso and Banyuwangi Regencies, but its management is carried out by the Natural Resources Conservation Agency (BKSDA). The distribution of economic benefits tends to be unbalanced because direct fees in the form of entrance ticket sales go to the central government as Non-Tax State Revenue (PNBP). The management plan for Ijen Crater TWA is included in several development and spatial planning plans, such as the Spatial Planning (RTRW) of Bondowoso Regency, the Spatial Planning of Banyuwangi Regency, and the Long-Term Management Plan for Ijen Crater TWA. Based on these conditions, research was conducted on the typology of stakeholder interactions and the factors influencing their management using a qualitative abductive approach and pattern-matching analysis technique. The research aims to identify the interactions occurring in the Ijen Crater TWA area with the various roles held by stakeholders and to identify the factors influencing them. The research results show that the interactions in managing Ijen Crater TWA include coalitions, coordination, cooperation, networking, and coexistence. The findings from the research can be used as a consideration in developing governance strategies in infrastructure planning to spatial planning in conservation areas involving multiple stakeholders.

Abstract

This study focuses on assessing the density of mangrove forests on the north coast of Demak Regency as an independent mitigation effort against tidal flooding. The impact of tidal flooding can be observed directly, such as damaged ponds and agricultural land, inundated road infrastructure, submerged houses, and disruption of livelihoods. This study is crucial because it provides data and spatial analysis to understand the current level of mangrove density, identify vulnerable areas and inform appropriate mitigation actions before the impact of tidal flooding. The study's novelty is that it focuses on specific density and vulnerability levels and uses significant short-term cover change analysis. Using spatial analysis methods through Geographic Information Systems (GIS) and satellite imagery from 2018-2023, several areas along the coast have mangrove densities varying from 1200-3400 trees per hectare. There was a 27.3% reduction in mangrove cover mainly due to changes in land use to ponds. Overlay analysis combining mangrove density with flood hazard maps and geographic information also maps how different mangrove areas are strongly related to tidal flooding. Areas with mangrove density <2000 trees per hectare are much more vulnerable to tidal flooding, which is worse at lower and better at higher ranges. The findings suggest that coastal engineering using soft hybrids, which integrate breakwater structures and mangrove rehabilitation, will be more effective in achieving long-term coastal resilience than using hard engineering techniques alone, support the integration of mangrove density thresholds into coastal infrastructure planning to enhance resilience against tidal flooding. As an effective policy for coastal management, a minimum standard of 3,000 mangrove trees per hectare is needed, and Demak Spatial Planning is needed to focus more on mangrove conservation within the Demak policy framework.

Abstract

Kinerja tenaga kerja merupakan faktor utama dalam penyelesaian proyek konstruksi. Pekerjaan pemasangan granite tile di area sempit lebih menghadirkan tantangan tersendiri akibat banyaknya potongan yang tidak dapat dimanfaatkan secara optimal, sehingga meningkatkan biaya melebihi RAB proyek. Penelitian ini menganalisis kinerja tenaga kerja dalam pemasangan granite tile pada area sempit dan luas, yang berdampak pada efisiensi biaya proyek konstruksi. Pekerjaan di area sempit lebih kompleks karena banyaknya potongan yang tidak dapat dimanfaatkan secara optimal, sehingga realisasi biaya sering melebihi RAB. Studi ini bertujuan menentukan koefisien tukang pasang serta membandingkan harga satuan upah pada kedua kondisi tersebut. Observasi lapangan dilakukan dengan metode MPDM untuk mengukur produktivitas pekerja, termasuk waktu penundaan dalam siklus kerja. Penelitian ini bersifat kuantitatif dengan studi pada proyek hotel yang memasang granite tile berukuran 40 × 40 cm. Hasilnya menunjukkan bahwa koefisien tenaga kerja untuk pemasangan di area luas adalah 0,124, sedangkan di area sempit 0,136. Biaya upah pemasangan di area luas tercatat Rp 44.400 per m², sementara di area sempit Rp 45.864 per m². Penelitian ini memberikan kontribusi praktis dalam perencanaan anggaran upah dan teknis dalam penyusunan analisis harga satuan pekerjaan untuk meningkatkan efisiensi proyek konstruksi.
