The increase in the number of terrorist attacks have shown that the effect of blast loads, such as the Friedlander blast load on elements of a building structure is a serious matter. Their effects on the structure should be taken into consideration in the design of the structure’s element. The objective of this study is to numerically analyze the blasting effect on stiffened orthotropic concrete plates within the elastic range of its material. The effects of the stiffener configuration, the location of the localized blast load as well as the influence of the thickness to the vertical deflection of the plate are solved numerically by using the two auxiliary equations in the x and y-directions. The analysis yields the vertical deflection versus time relationship which can be used to determine the stress distributions and the maximum stress value of the plate. This paper introduces the effect of the blast load on the orthotropic plates and essential techniques used to increase the capacity of a structure’s element to provide protection against explosive effects.

Purpose: Currently, public-rented flats in Jakarta Province are managed by the Management Unit of Public-Rented Flats (MUPRF), which uses the Regional Revenue and Expenditure Budget (RREB) as the source of its financing. However, several previous studies have suggested that the MUPRF change its institutional scheme, to be more independent and not rely on the RREB as its source of finance. The study aims to identify three variable groups, public-rented flats’ characteristics, alternative institutional and financial schemes and challenges in the change of institutional and financial schemes. Design/methodology/approach: This is a qualitative research, where both triangulation and the Delphi method are used to enrich findings. Triangulation is used to collect data from more than one source, and the Delphi method is used to gather opinions from experts and reach a consensus on the variables identified in the triangulation process. Findings: Based on the findings there are 11 variables of public-rented flats’ characteristics, three variables of alternative institutional and financial schemes and four variables of challenges in the change of institutional and financial scheme. Research limitations/implications: Through the triangulation process, only two sources were used, sources from previous research and regulations. In the Delphi method process, experts were staff from the Department of Community Housing and Settlement of the DKI Jakarta Province. Originality/value: This research will be used as the basis on developing a system dynamics on how the MUPRF works as a system to figure out whether it can be changed into the alternative scheme proposed, with all the characteristics and challenges identified.

Public-rented flats, which are intended for low-income society, have characteristics which are different from other type of public housing. Based on past literatures, there are 9 characteristics which are public-housing/residential unit’s specifications, supporting facilities, public facilities, surrounding facilities, social environment, household character, location, owner, and funding which are associated with the residents’ satisfaction towards public housing. Other than the issue of public-rented flats’ characteristics, some researches have also suggested changing the institutional and financial scheme of management unit of public-rented flats (MUPRF), especially the ones in DKI Jakarta Province. Therefore this initial research is conducted to identify the characteristic variables of public-rented flats that affect the choice of changing the institutional and financial scheme for the MUPRF. This research is a qualitative research using triangulation analysis based on 3 sources of data which are past literatures, regulations and interviews. According to the triangulation analysis the characteristics that affects the choice of changing the institutional and financial scheme for the MUPRF are public facilities, surrounding facilities, household character, and funding. Abstrak Rumah susun sederhana sewa (rusunawa) yang diperuntukan untuk masyarakat berpenghasilan rendah (MBR) memiliki karakteristik yang berbeda dengan unit hunian perumahan rakyat lainnya. Berdasarkan studi literatur terdapat 9 variabel karakteristik perumahan rakyat yaitu spesifikasi perumahan rakyat/unit rumah tinggal, fasilitas pendukung, fasilitas umum, fasilitas lingkungan, lingkungan sosial, karakter rumah tangga, lokasi, pemilik dan pembiayaan yang diasosiasikan terhadap kepuasan penghuni pada perumahan rakyat. Selain isu terkait karakteristik perumahan rakyat, terdapat beberapa literatur yang mengusulkan perubahan kelembagaan dan finansial pada unit pengelola rumah susun (UPRS), khususnya di Provinsi DKI Jakarta. Oleh karena itu penelitian awal ini akan mengidentifikasi variabel-variabel karakteristik yang dapat mempengaruhi pemilihan skema-skema kelembagaan dan finansial pada UPRS. Penelitian ini merupakan penelitian kualitatif dengan menggunakan analisis triangulasi yang diperoleh dari 3 sumber data yaitu dari studi literatur, perundang-undangan dan wawancara. Berdasarkan hasil analisis triangulasi didapatkan variabel karakteristik perumahan rakyat yang mempengaruhi pemilihan skema-skema kelembagaan dan finansial pada UPRS adalah fasilitas umum, fasilitas lingkungan, karakter rumah tangga dan pembiayaan pembangunan.
