Every building needs maintenance on every component of the building. Before carrying out maintenance activities, planning is required for every aspect of maintenance in the building. Good planning can ensure achieving goals in carrying out maintenance that utilizes costs and time efficiently. This study aims to plan the implementation of hotel building maintenance to achieve cost efficiency and maintenance time. The implementation methods include making SOPs, checklist forms, cost planning and maintenance schedules. Planning for SOP is made by adding existing SOP from the hotel to several SOPs from ministerial regulations that the hotel has not implemented. Planning checklist forms, costs and maintenance schedules made for architectural, mechanical and electrical work are limited to a period of 1 year and use ministerial regulation no. 24/PRT/M/2008 to check its suitability with implementation in the field. This research shows that hotel building maintenance management planning is better than before. The maintenance management plan created is expected to help the hotel carry out maintenance activities efficiently and utilize costs and time.

Soft soil has high water content and low permeability, causing a high settlement and long time. Soil improvement with prefabricated Vertical Drain (PVD) can accelerate settlement in soft soils and primary consolidation time. Prefabricated Vertical Drain (PVD) functions to accelerate the release of water from the ground, and the accelerated settlement process, which is indicated by the degree of consolidation (U) reaching 90%, generally this method combines PVD and preloading (additional load). The required time to achieve a 90% degree of consolidation is determined by the PVD installation pattern (triangle pattern and rectangular pattern) and its distance. This study reviewed the effectiveness of PVD installation patterns with distance variations of (1 m, 1.3 m, 1.6 m, 1.9, 2.2 m, 2.5 m, 2.8 m, and 3.1 m). The analysis results show that in the triangular pattern, the time required to achieve a degree of consolidation of 90% (U90) is from 1 to 8.5 months, and in the rectangular pattern is from 1 to 9.5 months. The greater distance between PVDs, the more time is required to achieve a 90% degree of consolidation (U90). The PVD with a triangular pattern could reduce the 6% - 25% time to complete a degree of consolidation (U90) compared to the rectangular pattern. It can be noted that the installation triangle pattern is more effective than the rectangular installation pattern.

Soft clay has a low bearing capacity, high compressibility and low permeability. This condition causes soft clay soil to have a long settlement time. To overcome this soft soil condition, soil improvement methods are needed. One of the efforts is to use a combination of soil preloading methods, Prefabricated Vertical Drain (PVD), and Prefabricated Horizontal Drain (PHD) methods. Calculating soil settlement with soil improvement is carried out using the Asaoka method, which is a field observation method, and the theoretical method using the Terzaghi method. Based on the calculation results of field observations using the Asaoka method, the average degree of soil settlement is 93.5%. The calculation results of the Asaoka method are recalculated using a back calculation to produce a new parameter value, namely the horizontal consolidation (Ch) value, which is then compared with the Ch value in the previous plan. In the Terzaghi method, the average soil settlement value is 1.205 meters. The results of soil settlement value are used to analyze the height of the embankment based on the load ratio requirement in SNI 8460: 2017, where the load ratio on the ground is ≥ 1.3 times the planned load under service conditions. Based on the monitoring results, a load ratio value of 0.875 was obtained so that the SNI requirements carried out a re-planning of the landfill. Then, proceed with the design of PVD and PHD. The results obtained in planning use triangular PVD patterns with a distance between PVDs of 1 meter.

Ikhlas Waste Bank is a newly established waste bank in 2023, located in Perumahan Putri Tujuh II, Sidomulyo Barat Village, Pekanbaru City. This waste bank currently has a relatively small number of customers, comprising only about 24% of the households. Additionally, the activities at the waste bank are still in the early stages of sorting waste. Therefore, the development of the waste bank is expected to improve waste management, both in terms of increasing the number of customers and expanding the range of activities. The method for this initiative involves motivating and educating residents through outreach and socialization. The material includes encouraging residents to raise awareness about reducing waste at landfills (TPA) and turning waste into money by depositing it at the waste bank. Furthermore, training is provided on creative activities to utilize waste through 3R (Reduce, Reuse, Recycle) practices. The 3R waste utilization training is very popular among residents, as it provides new skills and knowledge and offers economic benefits. Various recycled products are made from waste, such as wallets, bags, laptop cases, tumbler covers, and more. These products can be used personally or marketed online. Thus, the waste bank not only collects waste from the community but also transforms it into useful items.

This research focuses on the design of earthquake-resistant houses in West Sumatra Province to improve the structural quality of residential buildings. Significant damage to houses caused by previous earthquakes poses a serious threat, especially as it can hinder evacuation processes during disasters. Ensuring individual safety is a top priority in evacuation efforts, making it crucial to build earthquake-safe homes, whether through new construction or renovation, to minimize the risk of casualties. The study employs a quantitative approach guided by the earthquake-resistant house requirements handbook developed by JICA and the Ministry of Public Works. The result is an alternative DED design for a Type 45 house suitable for West Sumatra. This single-story house is designed on hard soil with a structure that meets earthquake standards. The analysis results show the structural specifications as follows: the foundation uses stone with a bottom dimension of 80 cm, a top dimension of 40 cm, and a height of 80 cm; BS beams measure 15 cm x 30 cm; RB beams 15 cm x 20 cm; and columns 20 cm x 20 cm. The average Safety Factor (SF) values are BS beams 1.04, RB beams 1.3, columns > 3, and stone foundation 3, indicating that the planned sections meet the requirements for earthquake-resistant houses. This study aims to contribute to disaster risk mitigation and serve as a guide for communities in constructing earthquake-resistant homes, especially in the West Sumatra region.

Konstruksi infrastruktur jalan tol dapat mengalami kerusakan sebelum masa layanan yang direncanakan tercapai. Penurunan tanah dapat terjadi apabila infrastruktur transportasi dibangun di atas lapisan tanah lunak, sehingga menyebabkan kerusakan struktur dan geoteknik yang cukup besar. Penelitian menjadi sangat penting dengan mengambil studi kasus pada Jalan Tol Palembang-Indralaya STA 1+670 yang berada di atas lapisan tanah dengan nilai N-SPT < 10 dan tanah lunak mencapai kedalaman 16,95 m. Penelitian bertujuan untuk menguji efektivitas aplikasi preloading dan prefabricated vertical drain (PVD) dalam mempercepat proses penurunan tanah dasar pada jalan tol tersebut. Metode yang digunakan dalam penelitian adalah dengan mengombinasikan metode preloading dan PVD. Metode preloading menggunakan sistem surcharge, menempatkan beban timbunan pada tanah dasar dengan tinggi desain 5 m. Metode PVD dengan memasang alat vertical drain ke dalam lapisan tanah lunak. Data yang diperlukan meliputi layout lokasi dan data tanah dasar, yaitu data tanah hasil uji lapangan dan laboratorium. Hasil penelitian menunjukkan bahwa penurunan yang terjadi sebesar 1,556 m dengan derajat konsolidasi 90% selama 2,149 tahun. Selanjutnya, setelah memasukkan metode PVD, waktu penurunan tanah dasar dengan derajat konsolidasi 90% menjadi lebih cepat, yaitu dua bulan dengan pola pemasangan segitiga dengan jarak 3 meter. Pada jalan tol dari Palembang menuju Indralaya, pendekatan gabungan antara preloading dengan PVD terbukti bermanfaat dalam mempercepat proses penurunan tanah dasar. Penelitian mengimplikasikan bahwa kombinasi metode preloading dan prefabricated vertical drain (PVD) dapat dipilih sebagai metode perbaikan tanah lunak untuk mempercepat penurunan tanah dasar.
