Abstract

Abstrak Indonesia dan beberapa negara tetangganya mengadopsi standar pembebanan angin internasional seperti ASCE, Eurocode, AIJ, AS/NZS, dan NBCC, yang dikembangkan pada kondisi geografis yang berbeda dibandingkan dengan daerah Asia Tenggara, sehingga diperlukan studi komparasi untuk mengetahui perbedaan fundamental dalam pembebanan angin dan hasil respons struktur yang didapatkan dari masing-masing standar pembebanan dengan kondisi angin di Indonesia. Hasil studi komparasi menunjukkan bahwa secara garis besar, masing-masing standar pembebanan menggunakan pendekatan yang sama dalam menentukan beban angin. Perbedaan utama terdapat pada periode ulang kecepatan angin yang digunakan dan nilai averaging time yang digunakan untuk menghitung faktor hembusan. Kemudian, terdapat juga perbedaan pada faktor-faktor lingkungan yang diperhitungkan untuk mendapatkan tekanan velositas, penggunaan persamaan dan nilai gust effect factor serta koefisien tekanan, dan perhitungan beban angin di masing-masing arah pada tiap standar. Studi komparasi ini juga menunjukkan bahwa untuk sebuah kasus struktur tinjauan berupa bangunan super tinggi yang berlokasi di Jakarta, standar pembebanan ASCE memberikan beban angin dan respons struktur terbesar. Kata-kata Kunci: Beban angin, komparasi pembebanan angin, respons struktur, standar pembebanan angin, struktur super tinggi Abstract Indonesia and its neighboring countries adopt international wind loading standards, such as ASCE, Eurocode, AIJ, AS/NZS and NBCC, which are developed in different geographical conditions compared to South-East Asia region. Thus, a comparative study is needed to see the fundamental differences in wind loading and structure response obtained from each loading standards with Indonesia’s wind condition. Comparative study shows that in general, each loading standards use the same approach in calculating wind load. The main differences of each loading standards come from the return period of the wind speed used in calculating wind load and averaging time used in calculating gust factor. Each standard also has differences in the factors used to calculate velocity pressure, the expression and method of gust effect factor and pressure coefficient, and methods for calculating all three directions of wind load in each standard. This study also shows that for the observed structure located in Jakarta used in this study, ASCE standard gives the highest value of design wind load and structure response.

Abstract

Currently, 24.5% of the population of Bima City lack access to sanitation. The issue is predominantly concentrated in densely populated urban slums along the riverbanks, influenced by the cultural and societal context of Indonesian society. From 2021 to 2022, a comprehensive mixed-method study was conducted in three urban slums, applying the Integrated Framework for Sanitation Services (IFSS) to explore individual aspects within a socio-cultural context. Combining quantitative and qualitative methods, the research involved a household questionnaire survey and in-depth interviews (IDI). The study revealed that individual aspects are shaped by perceptions of the convenience of open defecation and latrine use as well as experiences with shared latrines, driving the adoption of private latrines. Challenges such as financial constraints and limited construction capabilities in urban slum communities often hinder latrine construction, though cultural and traditional values (adat) in the Bima community in urban slums help to alleviate these obstacles. A recommendation is made to enhance the monitoring of sanitation adoption progress, focusing on the sanitation system’s functioning and adherence to the sanitation hierarchy. Despite awareness of the importance of safe disposal, its impact on sanitation behavior in Bima City’s urban slums has been constrained, underscoring the imperative for effective behavior change communication strategies.

Abstract

ABSTRAKKebutuhan akan sanitasi merupakan salah satu kebutuhan dasar manusia sebagai bagian dari upaya perlindungan kesehatan dan mendorong peningkatan ekonomi melalui peningkatan kapasitas pemerintah kabupaten/kota untuk mengimplementasikan program sanitasi di Indonesia. Kota Bima sebagai lokasi studu dengan permasalahan sanitasi perlu didukung oleh stakeholder. Penelitian ini dapat melengkapi dokumen yang sudah dibuat. Penelitian ini dilakukan dengan metode campuran atau mixed method yang dilakukan secara kualitatif pada metode Stakeholder Analysis (SA) dan metode kuantitatif pada metode Social Network Analysis (SNA). Stakeholder Analysis dilakukan dengan focus group discussion (FGD) sedangkan Social Network Analysis dilakukan berdasarkan kuesioner yang diisi oleh peserta FGD saat acara FGD berlangsung. Hasil rangkaian penelitian di Kota Bima: teridentifikasi 52 stakeholder yang memiliki kepentingan terkait sanitasi di permukiman kumuh; terpetakan ada 8 key actors, 7 important actors, 6 interested actors, dan 9 additional actors ; teridentifikasi 4 influential stakeholders yang juga adalah key actors. Secara umum kekohesifan (density) semua jenis kerja sama pada Kota Bima tidak cukup baik, yaitu 7,7%. Diperlukan peningkatan kerja sama dengan Perusahaan Swasta, Masyarakat, dan Akademisi untuk penanganan sanitasi di permukiman kumuh Kota Bima. Kata kunci: sanitasi, kawasan kumuh, stakeholder analysis, social network analysis, Kota Bima ABSTRACTThe need for sanitation is one of the basic human needs as part of efforts to protect health and encourage economic improvement to increase the capacity of district/city governments to implement sanitation programs in Indonesia. Bima City as a study location with sanitation problems needs to be supported by stakeholders. This research was carried out using mixed methods which were generally carried out qualitatively using the Stakeholder Analysis (SA) method and quantitatively using the Social Network Analysis (SNA) method. Stakeholder Analysis was carried out using a focus group discussion (FGD) while Social Network Analysis was carried out based on a questionnaire filled out by FGD participants during the FGD event. The results of research series in Bima City: identified 52 stakeholders who have an interest in sanitation in slum settlements; there are 8 key actors, 7 important actors, 6 interested actors, and 9 additional actors; there are 4 influential stakeholders who are also key actors. In general, the cohesiveness (density) of all types of cooperation in Bima City is not good enough, namely 7.7%. There is a need to increase cooperation with private companies, communities and academics to handle sanitation in Bima City slums. Keywords : sanitation, slum area, stakeholder analysis, social network analysis, Bima City
