Time Assessment on Sensor Stability for Sound Absorption Measurement

In previous study, humidity consistency had been proven as significant contributor to the stability of sensor in measuring absorption coefficient of acoustical material. This phenomenon becomes critical as method of in-situ measurements naturally involve environmental variables, where temperature and humidity may vary. This research applies two similar pu-sensors (pu-1 and pu-2) in series of calibration and EA-method measurement sets then comparing both results on absorption characteristics through standard deviations, each in various controlled humidity. In every of four measurement sets, both sensors behave in similar trend in responding different humidity changes, Dj. The higher the humidity difference, Djbetween measurement sets, the bigger deviation of results occurred. To confirm this humidity effects on sensors’ stability on measurement of absorption coefficient by EA-method, further investigation were performed by statistical correlation between humidity levels and the time of measurements (4 sets of separated time). Environment humidity manually controlled in ranges of 30 - 60% by set of fans and humidifiers throughout set of measurement, while deeper understanding on the resulted deviations were discussed by evaluation on the sensors working principles and how its sensibility may effected by humidity in the environment.  Based on time and humidity difference, Dj  statistical simulation, correlation between sensor’s calibrations and their responses in 4 separated time of experiments had emphasized the above phenomenon. No significant differences on both sensors’ deviation in each of the experiment time sets, leaving humidity as the deviation source with less correlation to time of measurements

The Relation between Dividend and Financial Constraints to Firm Value

This study examines the relation between dividends and financial constraints to firm value using publicly traded firms in Indonesia from 2013 to 2017. The very exploration used a repeated cross section regression method to understand monotonic and non-monotonic alliance between dividends and financial constraints to firm value. The non-monotonic correlation measured by dummy variables for 6 dividends categories, i.e. 0 category is defined as firms that did not pay dividends and category 5 is defined as firms that pay dividends with the highest quintile. It is found that monotonic bond lowers the financial constraints that has more important and consistent positive effects on firm value relative to dividends. These findings imply investors to have higher preferences for a firm’s ability to realize good investment projects and provide higher future profits, relative to current profit in the form of dividends. It also found that non-monotonic connection between dividends and firm value and dividends and financial constraints have relatively equal positive effect to firm value

Produksi Gas Metana Dari Pengolahan Sampah Perkotaan Dengan Sistem Sel

Waste to energy now become one of the technology solution that is in many developed countries, in an effort to reduce greenhouse gas emissions from waste. Urban organic waste is a potential source of greenhouse gases. Methane gas is an energy source that can be used as fuel. It is difficult to find land for Landfill alocation in the major cities and often becomes a difficult social problem. Structured Landfill Cell is used to treat the waste at the landfill, with the aim to use land more scalable, easier waste management and control, better sanitation, better water control leachate and gas produced can bemanaged optimally and compost can be utilized with the production and quality control.This new system was first used in Indonesia by PT Navigats Organics Energy Indonesia in landfill Suwung, Denpasar, Bali. There are 5 cells already built in Suwung and two of cells have been filled with garbage. Each cell contains 12,000 m3 soliswaste. Observations carried out on gas productivity of two cells that have been filled, with a dry treatment on cell 1 (dry cell) and a wet treatment in cell 2 (wet cell). The observed gas is CH4, CO2,and O2 as the main parameters, with the addition parameters are CO and H2S. The instrument used is the GA 2000 Plus. Observations of two cells made for 4 months, with the content of CH4 around 40 to 50% in the first month and gradually decreased to reach 18 to 25% in the fourth month. Carbondioxyde going up and down following condition of CH4 and its value ranges between 16 and 28%. Oxygen consentration around 2 to 14%.For keeping engine performance the consentration of methane should more than 28%and O2 content lower than 6%. Cell with watering will temporarily reduce CH4 and CO2 and O2 increase, but it is slowly rising again. Carbonmonoside values tend to increase with age garbage (10 sd 350 ppm), whereas irregular H2S values ranging 0 up to 24 ppm, allegedly associated with the low protein content in the trash. Sewage treatment system is proven to increase CH4 gas, yet still needed modifications of structure and the gas collector pipe system so that productivity can be improved

Deep Inelastic Scattering from off-Shell Nucleons

We derive the general structure of the hadronic tensor required to describe deep-inelastic scattering from an off-shell nucleon within a covariant formalism. Of the large number of possible off-shell structure functions we find that only three contribute in the Bjorken limit. In our approach the usual ambiguities encountered when discussing problems related to off-shellness in deep-inelastic scattering are not present. The formulation therefore provides a clear framework within which one can discuss the various approximations and assumptions which have been used in earlier work. As examples, we investigate scattering from the deuteron, nuclear matter and dressed nucleons. The results of the full calculation are compared with those where various aspects of the off-shell structure are neglected, as well as with those of the convolution model.Comment: 36 pages RevTeX, 9 figures (available upon request), ADP-93-210/T128, PSI-PR-93-13, accepted for publication in Physical Review

Urban evictions, public housing, and the gendered rationalisation of Kampung life in Jakarta

The dispossession of urban communities across class and racial lines is a global phenomenon linked to the expansion of international investment in the development of ‘exemplary’ city space. However, city evictions are also historically-informed and gendered processes which are continuous with past colonial and postcolonial urban rationalisation projects. Drawing on testimonies of women evictees in Jakarta, as well as interviews with public housing managers, this article details the gendered nature of the rationalisation of urban life in the context of a contemporary evictions regime. We argue that the rationalisation of urban space serves to sharpen the gender order by placing material constraints on women’s roles, limiting their economic activities, and defining them as hygiene-responsible housewives. Further, and in turn, the limited provision of ‘rusunawa’ public housing, which we show to be a gendered spatial and social transition informed by state doctrine on the family, provides the state with justification for dispossession itself. Finally, women’s everyday acts of refusal and resistance show not only that kampung forms of social life continue to be preserved in Jakarta, but also that rationalisation itself is a negotiated and contingent process

The Gift of Future Time: Islamic Welfare and Entrepreneurship in 21st century Indonesia

The attainment of religiously informed and socially responsible wealth is a desire widespread in the metropolises of Java, Indonesia, especially amongst the pious middle classes. This article aims at an understanding of the emergence and effects of an early 21st century desire for pious entrepreneurial success, by focusing on the practices people consistently and regularly undertake in order to actualise this. It claims that the religiously informed desire for entrepreneurial success is permeated by a mode of temporality that privileges the future at the expense of the past and the present. This temporal orientation has important consequences for subject-making, as it forces the subjectivities created to take a distinctively asymptotic form, resulting in the production of self-differing subjects; that is, subjects in which past, present and future actualisations lack coincidence and complete convergence

The Privatization of Metropolitan Jakarta's (Jabodetabek) Urban Fringes:The Early Stages of "Post-Suburbanization" in Indonesia

Problem, research strategy, and findings: Recent metropolitan development in developed countries is associated with post-suburbia, or a decline in population in the former central city and the growth of polycentric structures outside the traditional core. Current urban development in Asian cities, particularly in the Jakarta metropolitan region (Jabodetabek), also reflects an early stage of post-suburbia. We examine physical development patterns and the changing role of public and private sectors, although our approach is descriptive in nature. The rapid growth in fringe areas that have developed from dormitory communities into independent towns, triggered by privatization of industrial estates and multifunction new towns, shows typical post-suburban patterns. The national government's pro-growth economic policies and the local autonomy granted to local governments have given the private sector the power to largely control the acquisition, development, and management of land in fringe areas, accelerating post-suburban development patterns.Takeaway for practice: Planners in developing nations must be alert to the rapidly increasing role of the private sector, recognizing how the private sector can help the government to respond to regional needs for housing, jobs, shopping and educational opportunities, and infrastructure while understanding the key role that planning can and should play in ensuring private sector actions do not exacerbate regional problems and lead to uncoordinated public responses
