Waste sorting at the source has been enforced by the Government of Indonesia since the implementation of the Waste Management Law No. 18 Year 2008. However, waste sorting is still not a popular practice in households. We present the findings of a survey conducted for 900 households' receptivity regarding waste sorting at the source. A logistic regression model allowed us to examine the socioeconomic characteristics determining the public receptivity regarding waste sorting at the source. The results show that household heads' years of education, family members, current sorting practices and understanding of sorting obligations, are the factors determining the public receptivity regarding waste sorting at the source. Moreover, we also assessed the main reasons why households have not practiced waste sorting at the source yet. The three main reasons are mixed collection and transport (26%), lack of sorting facilities (23%), and lack of time (22%). The findings provide useful insight for the local government in developing mechanisms for the implementation of waste sorting at the source on larger scales as a part of the waste reduction program.

Preservation act of the heritage area in Gresik is still in draft, and many heritage objects are yet formally legalised. This situation affect to the decrease of heritage objects from 500 units to 125 units for the last 20 years. The heritage area that situated in urban area has many values while their advantage are not yet maximalised in urban development process. This article is part of Gresik preservation concept research which aiming in building criterion for preservation concepts by grounding up perception and values that lies in the community either who lives in an urban heritage area of Gresik, Kampung Kemasan, and the remote community who are connected to Kampung Kemasan but may not live there in present. Preservation concept that build from the locals may describe the community participation level to preserve a city's heritage area and lead them into a heritage tourism through any capacity. This capacity represent the city's resilience through tourism. The resiliency aspect are then examined through social capacity that exist in Kampung Kemasan community related to heritage tourism. This article are using qualitative approach in building factors that affected the heritage tourism through the social capacity indicators. Focus groups discussions and in-depth interviews were held as a method to ground up perception, and a set of trancript data are analysed through content analysis method. The finding reveals some factors related to social capacity description which consists of local community daily activities that mostly situated in or near the Kampung Kemasan and also their commitment to held any annual activities that seen as a potencial aspect to involve the locals in urban heritage management; the existence of a social capital through space and time they have managed together to discuss things about their settlements; the existence of Nyi Ageng Pinatih and Nyi Ageng Arem-Arem's tomb (the former figures of Kampung Kemasan) as a focus of attraction for religious visit; and the aesthetic and originality factors of every building in Kampung Kemasan that tells many stories about the histories of Kampung Kemasan.

Fatigue is a condition experienced by a person that causes a decrease in a person's vitality and productivity. Fatigue can be characterized by slowed reaction time and fatigue. People’s condition is a significant factor in driving safety. Based on this increase in the number of accidents according to the Central Statistics Agency (BPS), experts conducted research on detecting fatigue that often occurs. In this study, a system that can detect fatigue is developed using parameters obtained from physiological indicators such as heart signals by using the Low Frequency/High Frequency ratio parameter, muscle signals using the average frequency domain of the muscle signal and oxygen saturation. The detection tool in this study uses the ECG Click Module, EMG Click Module, and Oximeter Click which will be connected to the ARM microcontroller, namely STM32F407ZG. The parameters that have been obtained are processed using the Fuzzy Logic method to determine the level of fatigue. Based on the tests results carried out on three subjects, parameter values were obtained where in the subject the three parameters entered into fuzzy logic, it was found that the three subjects were detected in a fairly tired state. The aggregated output that found from subject A was 0.6303, the aggregated output of subject B was 0.77948, and the aggregated output of subject C was 0.79188. Furthermore for future research development, the signal processing can be done more complex, besides that signal processing and fuzzy logic processing can be embedded so the process runs in realtime.

In a planning process, appropriate methods in order to understand the problems is needed so that proper planning products targeted to answer the challenge on a case study. Root cause analysis (RCA) is a qualitative analysis method that serves to attract understanding the root causes of problem which is need to be considered in the formulation stage of product planning. The tourist area of cultural heritage Kampung Kemasan has potential as a tourist development area but his condition is not developed well. Kampung Kemasan chosen as a case study to be aligned with the functions deemed appropriate method of RCA as a tools to understand the root cause of an event. The use of RCA is expected to become effective tools for basic guidelines for the formulation of the product development of the region based on a comprehensive understanding of an event.
