Properties of Cold Asphalt Emulsion Mixtures (CAEMs) Using Materials from Old Road Pavement Milling

AbstractCold Asphalt Emulsion Mixtures (CAEMs) can be produced at room temperature. CAEMs can incorporate milled old road pavement. Some virgin aggregate and rice husk ash as filler material and cement was added into the mixture. The samples were subjected to compaction delay for up to 24hours and cured at room temperature for up to 8 days and cured to full curing condition. The samples required more pronounced compaction effort. The cured samples met the minimum stability of 3 KN. The increased strength at early aged at tropical room temperature was found more dominant due to the water evaporation than cement content

Analisis Kerusakan Struktur Bangunan dan Manajemen Bencana Akibat Gempa Bumi, Tsunami, dan Likuifaksi di Palu

The strong column-weak beam is a design concept that needs to be implemented and considered in the planning of building structures (high-rise and low-rise buildings). Generally, structural failure occurs at beam-column joints. Such failure occurred due to the lack of attention to good and correct design concepts. The detailing of reinforcement for columns, beams, and beam-column connections has not yet fully implemented the SNI-2847-2019 standard which results in the reinforcement cannot withstand the combination of tensile, compressive, and shear forces that occur during an earthquake. In addition, the incomplete design of strong column-weak beam in building planning causes the building to fail in the column structure when receiving axial forces. The purpose of this study was to analyze the structural damage and the disaster management system applied during the earthquake in Palu. The research is carried out by investigation/survey methods on the study area as well as checking and recording the data about damage condition of buildings and conducting a hammer test (non-destructive test) to get the strength value of the concrete. Testing result showed the compressive strength value of the f’c concrete used is 20 to 48 MPa. In addition, the details of stirrups reinforcement are also not fully understood about their function on beams and columns, which results in the installation of stirrup reinforcement does not meet the criteria for bending angles of 90˚, 135˚, 180˚ and the addition of tensile and compressive reinforcement lengths. The high potential for earthquake hazard causes Palu and its surroundings tend to have an earthquake risk. For this reason, it is necessary to implement disaster mitigation for Palu region, which aims to reduce the number of casualties when natural disasters occur, both human and property loses.Strong column-weak beam merupakan konsep desain yang perlu diterapkan dan diperhatikan dalam perencanaan struktur gedung (gedung bertingkat tinggi dan gedung bertingkat rendah). Umumnya kegagalan struktur terjadi pada sambungan balok-kolom (beam-column joint). Kegagalan tersebut terjadi karena kurangnya perhatian terhadap konsep desain yang baik dan benar. Detailing pembesian pada kolom, balok, dan sambungan balok-kolom masih belum secara penuh menerapkan standard SNI-2847-2019 yang mengakibatkan tulangan tidak berfungsi sepenuhnya dalam menahan kombinasi gaya tarik, tekan, dan geser yang terjadi saat gempa. Selain itu prinsip desain Strong column-weak beam yang tidak lengkap di dalam penerapan perencanaan bangunan mengakibatkan bangunan mengalami kegagalan pada struktur kolom saat menerima gaya axial. Tujuan penelitian ini adalah untuk menganalisis kerusakan struktur yang terjadi dan sistem manajemen bencana yang diterapkan saat terjadi gempa di Palu. Metode penelitian dilakukan dengan metode investigasi/survei ke lapangan dan melakukan pengecekan dan mencatat data mengenai kondisi kerusakan bangunan dan melakukan uji hammer test (pengujian nondestruktif) untuk mendapatkan nilai dari kekuatan beton. Dari hasil pengujian yang dilakukan diperoleh nilai kuat tekan beton f’c yang digunakan adalah (20-48) MPa. Selain itu detail penulangan sengkang stirrups juga belum sepenuhnya dipahami fungsinya pada balok maupun kolom yang mengakibatkan pemasangan tulangan sengkang tidak memenuhi kriteria aturan bengkokan sudut 90˚, 135˚, 180˚ dan penambahan panjang penyaluran tulangan tarik dan tekan. Potensi bahaya gempa yang tinggi mengakibatkan wilayah Palu dan sekitarnya cenderung memiliki risiko bencana gempa bumi. Untuk itu mitigasi bencana sangat perlu diterapkan di wilayah Palu yang bertujuan untuk mengurangi jumlah korban jiwa pada saat terjadi bencana alam, baik manusia maupun harta benda

Female sex workers (FSW) is marginalized social group having a high vulnerability of health problems. Effort to expand national health insurance on FSW is still limited, so it is necessarily performed in order to support the achievement of universal health coverage. This study aimed to obtain the depiction of the insurance access among FSW in Denpasar. This study was qualitative. Data was collected through in-depth interview of 15 FSW and four pimps in Denpasar from August to October 2014. The interview result was analyzed using thematic analysis. The analysis framework used was The Health Access Livelihood Framework. The insurance ownership among FSW in Denpasar was low, even though some FSW were willing to be participants and afford to pay the premium. Factors inhibiting the insurance access were the lack of knowledge regarding registration procedures and portability, fear of premium payment sustainability, negative perceptions of quality of services that would be received if using the insurance, incomplete population administration and policy requiring independent non-premium support receiver participants to register all of their family members. The insurance access among FSW was hindered by individual, service and policy factors that need to be conquered to increase the insurance coverage among FSW

Implementation of smoke-free law in Denpasar Bali: Between compliance and social norms of smoking

Background: Since 2013, City of Denpasar government has adopted a smoke-free law. Implementation of the law faces several obstacles, partly due to the high social acceptability of smoking in the city, where cigarette and smoking has been deeply engrained within social life and become part of hospitality. This study aims to assess the smoke-free law compliance and to explore the social norms that may affect the compliance. Design and Methods: The study was a mix of cross-sectional compliance survey and qualitative exploration conducted in Denpasar in 2019. Survey included 538 samples, which were selected using stratified random sampling and a walking protocol. The qualitative data was collected through in-depth interviews and Focus Group Discussion (FGD) in four sub-districts of Denpasar.Results: Of the 538 venues, 32.9% complied with the seven compliance indicators. The university has the highest compliance (83.3%), while public places including worship places have a low compliance. The three most common violations were the absence of no-smoking signage (58.6%), provision of ashtray (17.5%), and smell of tobacco smoke (15.8%). The poor compliance was related to the lack of awareness of the regulation, and the fact that smoking is highly acceptable and part of the culture. The informants highlighted the essential role of public figures and potency of local policy as social disapproval of smoking.Conclusions: Compliance to the smoke-free law in Denpasar remains low, continuous education, socialization and improved supervision are crucial. Meanwhile, social and cultural acceptance of smoking is considered as an essential factor that hampers the implementation of the smoke free law
