This study focuses on combining precast concrete system and base isolation technique that could lead to a high-performance seismic resistance structural system. Some previous experimental results on precast concrete modules are presented and discussed. Principles and numerical implementation of base isolation technique are described and presented in details. Analysis of life cycle cost that compares the conventional system and a system that combines precast concrete system and base isolation technique shows promising results. The result from this study is a structural system that has high seismic performance and cost efficiency for certain class of structures and site conditions.

Abstract-Flooding as a result of global climate change that hit several areas in Jakarta, Indonesia, in particular the area around the river banks and reservoirs cause suffering to the residents who are generally poor segments of society. Relocation is one solution. However, the limited land in urban areas, forcing them to move to a vertical housing. Changes in psychology, social, economic and cultural as a result of this relocation need proper handling. Therefore the determinant factor that affects the success of the relocation is important to note. This study is expected to know the opinion of the inhabitants of the vertical housing. The data used in this study is primary data and secondary data. Primary data were collected through questionnaires distributed to the inhabitants of the banks of the Ciliwung River residents in Kampung Pulo, while the secondary data obtained from the study documentation and interviews in Jakarta Provincial Office and Residents Association office in Kampung Pulo. The results of the study showed that location, environmental factor, and rental price, affect the considerations to stay in the flat. Partial test showed that the proximity of work is the most influential factor. Flat located near KampungPulo is the top choice of respondents. Expected rents are less than four hundred thousand rupiah ($40) per month and the number of desired floor flats ranging between five to eight floors.

Artikel ini berisi kegiatan Focus Group Discussion (FGD) sebagai salah satu rangkaian dari kegiatan pendampingan Tim Pelaksana Pengabdian kepada Masyarakat dari Universitas Persada Indonesia YAI dalam pembuatan peta digital interaktif kepada mitra usaha PT. Cakar Langit Indonesia yang bergerak di bidang jasa wisata outdoor Sentul Bogor. Pendampingan tersebut dilakukan dalam rangka mendukung visi dari mitra, selain memberikan pelayanan wisata outdoor secara profesional, juga mengutamakan kepedulian kepada alam dan masyarakat lokal. Oleh karena itu, pembuatan peta digital yang menjadi kebutuhan mitra, selain menghasilkan layanan informasi yang interaktif dan menarik bagi wisatawan, tetapi juga memfasilitasi masyarakat lokal untuk terlibat dalam wisata trekking Sentul Bogor. Metode yang digunakan adalah berupa focus group discussion dan pengisian kuesioner untuk mendapatkan masukan yang dapat digunakan sebagai pedoman dalam pembuatan peta wisata trekking Sentul Bogor. Peserta FGD terdiri dari Tim Pelaksana Pengabdian kepada Masyarakat, narasumber ahli, narasumber wisatawan, mitra usaha PT. Cakar Langit Indonesia, pemandu lokal dan masyarakat pelaku usaha. Hasil FGD menyimpulkan bahwa pembuatan peta perlu dibagi 2 dalam bentuk dan peruntukannya, yaitu untuk peta digital interaktif berbasis website untuk wisatawan dan peta dasar berbasis GIS untuk pengelola wisata serta pemandu wisata.
