Kajian numerik distribusi udara pada ruang ber-AC untuk mencapai tingkat efisisensi energi yang optimal
No full textThe demand for household energy in Indonesia is dominated by air conditioning sector. One of the efforts to optimize air conditioner (AC) is to figure out the best air distribution pattern. Nowadays, there are three air distribution types of marketed AC; (1) perfect mixing, (2) displacement, and (3) radiant cooling. This research examines the influence of those types toward energy consuption to ensure indoor thermal comfort. It was conducted by conducting literature review, mathematical calculation, and numerical simulation. Based on SNI 03-6572-2001, the research applied comfort criteria of indoor air temperature of 24oC as setpoint with 28.1oC initial temperature. Energy consumption is estimated based on time required to achieve the setpoint. The fastest cooling time is obtained by displacement in 80 seconds, then perfect mixing in 112 seconds, and the longest is radiant cooling in 460 seconds. Energy calculation establishes three scenarios of heat load represented by air con’s idle time; (a) high load, 30 seconds, (b) moderate load, 60 seconds, and (c) low load, 90 seconds. For 300 hours of operational time per month, displacement consumes (a) 148.4, (b) 116.6, and (c) 96 kWh/month, whilst perfect mixing needs (a) 160.9, (b) 132.8, and (c) 113.1 kWh/month. Lastly, radiant cooling spends (a) 191.5, (b) 180.5, and (c) 170.6 kWh/month.
© 2018 Jackobus Ade Prasetya SeputraPenggunaan energi listrik bangunan rumah tangga di Indonesia didominasi oleh kebutuhan AC. Salah satu upaya untuk mengoptimalkan kinerja AC adalah dengan memperhatikan distribusi aliran udaranya. Di pasaran terdapat tiga tipe distribusi udara AC, yaitu (1) perfect mixing, (2) displacement, dan (3) radiant cooling. Penelitian menguji pengaruh tipe-tipe distribusi AC tersebut terhadap konsumsi energi pendinginan dengan metode studi literatur, perhitungan matematis, dan simulasi numerik. Kriteria kenyamanan termal bersumber dari SNI 03-6572-2001 dengan suhu udara 24oC sebagai titik tuju (setpoint) dari kondisi mula 28,1oC. Sedangkan perhitungan tingkat konsumsi energi didapatkan dari lamanya waktu mencapai setpoint. Waktu pendinginan tercepat dicapai oleh displacement, yaitu 80 detik, lalu perfect mixing dalam 112 detik, dan yang terlama adalah radiant cooling, 460 detik. Perhitungan matematis dilakukan dengan tiga skenario beban kalor yang diasumsikan menjadi lamanya waktu AC saat jeda (idle), yaitu; (a) beban besar, 30 detik, (b) beban sedang, 60 detik, dan (c) beban kecil, 90 detik. Dengan waktu operasional 300 jam per bulan, konsumsi energi displacement sesuai skenario adalah; (a) 148,4 kWh/bulan, (b) 116,6 kWh/bulan, dan (c) 96 kWh/bulan, perfect mixing; (a) 160,9 kWh/bulan, (b) 132,8 kWh/bulan, dan (c) 113,1 kWh/bulan, dan radiant cooling; (a) 191,5 kWh/bulan, (b) 180,5 kWh/bulan, dan (c) 170,6 kWh/bulan.

TINJAUAN YURIDIS TERHADAP PENGGUNAAN MATA UANG VIRTUAL (VIRTUAL CURRENCY) SEBAGAI ALAT TRANSAKSI DALAM PERDAGANGAN DI INDONESIA
No full textMuhammad Ade Surya Andar Prasetya, Herman Suryokumoro, S.H., M.S, Lutfi Effendi, S.H., M.Hum Fakultas Hukum Universitas Brawijaya email: [email protected] Â Abstrak Penelitian ini dilakukan guna mengetahui keabsahan penggunaan mata uang virtual sebagai alat transaksi dalam perdagangan di Indonesia. Pengingat pengaturan uang virtual belum dibuat oleh pemerintah dan mengakibatkan kekosongan hukum di masyarakat. Namun, semakin banyaknya pengguna serta jumlah transaksi yang terus meningkat menjadikan sebuah aturan tersebut menjadi sangat penting demi adanya suatu perlindungan bagi penggunanya serta kejelasan suatu hukum terhadap uang virtual tersebut. Penulisan artikel ini bertujuan untuk mengetahui legalitas dari penggunaan mata uang virtual berdasarkan analisa pada peraturan perundang-undangan yang sudah ada sebelumnya. Kemudian seluruh data diolah secara deskriptif analitis. Penelitian ini didorong karena belum adanya aturan mengenai mata uang virtuaal sehingga belum adanya kepastian dan perlindungan hukum bagi penggunanya. Kata kunci: mata uang virtual, alat transaksi, perdagangan. Â Abstract This research was conducted to determine the validity of using virtual currency as a transaction tool in trade in Indonesia. Considering that the regulation of virtual money has not been issued by the government and causing the vacuum of law in society. However, the increasing number of users and transactions make these regulations become very important for the protection of users and the legal certainty on virtual money. The writing of this paper aims to determine the legality of using virtual currency based on the analysis of pre-existing legislation. Furthermore, all data was processed in descriptive analytical manner. This research was motivated by the vacuum of law regarding virtual currency, so that there is no legal certainty and protection for its users. Keywords: virtual currency, transaction tools, trading
Ross-Ade
No full textDave Ross (1871-1943) and George Ade (1866-1944) were trustees, distinguished alumni and benefactors of Purdue University. Their friendship began in 1922 and led to their giving land and money for the 1924 construction of Ross-Ade Stadium, now a 70,000 seat athletic landmark on the West Lafayette campus. Their life stories date to 1883 Purdue and involve their separate student experiences and eventual fame. Their lives crossed paths with U.S. First Lady Eleanor Roosevelt, Henry Ford, Amelia Earhart, and Will Rogers among others. Gifts or ideas from Ross or Ade led to creation of the Purdue Research Foundation, Purdue Airport, Ross Hills Park, and Ross Engineering Camp. They helped Purdue Theater, the Harlequin Club and more. Ade, renowned author and playwright, did butt heads with Purdue administrators at times long ago, but remains a revered figure. Ross's ingenious mechanical inventions of gears still steer millions of motorized vehicles, boats, tractors, even golf carts the world over

Mapping the Energy ADE to CityGML 3.0
No full textIn order to limit the global warming to well below 2 degrees Celsius, all sectors have to reduce their greenhouse gas emissions and become more sustainable. This also includes the building sector, which is in Europe responsible for 40% of the total energy consumption (European Commission, 2020). A way to work towards this goal is by retrofitting the existing building stock to become more energy efficient. Urban Building Energy Modelling (UBEM) can help in this endeavour by identifying energy-saving potentials and thus to effectively allocate the required resources (Horak et al., 2022). Yet, UBEM involves many stakeholders which is why standards are crucial to facilitate data exchange and interoperability among them. In this context, the Energy ADE v1.0 was developed as an extension for the semantic 3D city model standard CityGML 2.0. It serves two purposes, first by storing energy related information on the individual building level, and second by providing the necessary input data for UBEM simulations (Agugiaro et al., 2018). However, in September 2021 CityGML 3.0 was released. The introduced changes directly affect the structure of the Energy ADE, which is why it cannot fully function on it anymore. This thesis therefore answers the question, how and to what extent the Energy ADE for CityGML 2.0 needs to be adapted to be conformant with the new CityGML 3.0 standard. It is accomplished by following a model-driven approach, where the UML class diagrams for the mapped Energy ADE are created first, before automatically deriving the corresponding XSD schema file. Through the lossless mapping itself, the Energy ADE is integrated as much as possible into CityGML 3.0, while also maintaining a logical symmetry. As such it accounts for the introduced changes of CityGML 3.0, by making use of the space and geometry concept, the versioning possibilities as well as the provided structures to model time-dependent data. The result is eventually tested and verified by converting a sample dataset to the Energy ADE for CityGML 3.0. This work provides an example on how other ADEs can be adapted to fit the new CityGML 3.0 standard and thus hopefully to the further establishment of it.Geomatic
A metadata ADE for CityGML
No full textWhile there exist international standards for geospatial metadata (ISO 19115), these are rarely used in practice for 3D datasets, and one of the OGC standards for 3D city models, CityGML, does not offer a mechanism to store metadata in a structured way. Having metadata in CityGML files, which are in practice often very large and complex, would provide us with the ability to quickly understand the nature of a dataset and to determine if it is relevant for a specific task. Alack of metadata introduces uncertainty into models that are already full of assumptions and estimations. In this paper, we first examine the metadata needs that are specific for 3D geographical datasets and propose ISO 19115compliant categories. We then describe how these can be used within CityGML by defining an Application DomainExtension (ADE), which allows us to store metadata for existing city objects of CityGML, as well as objects in other domain-specific ADEs. Our ADE, its schema in both UML and XSD, and sample datasets is openly accessible, and it can be easily extended to support application specific metadata. In addition the metadata elements have been added to the core of CityJSON. We also offer software to generate automatically many of the metadata categories and we propose coupling it with the source 3D dataset.Urban Data Scienc
George Ade\u27s Role in National Literature
No full textThe purpose of this study has been {l) to appraise the existing literary reputation of George Ade and (2) to determine whether or not he has made a substantial contribution to national literature.
In the investigation the hypothesis assumed was that the humor which critics see in George Ade\u27s work and the local color contribution which he made to national literature were of secondary importance to the author\u27s personal intention to be a realist.
The presupposition which has been adopted is that George Ade endeavored to be one of the exponents of the realistic movement. He recreated with his works what perhaps might be described as an authentic expression of realism in American literature. Whether Ade did or did not accomplish the realism he set out to convey in his writings, he remains a minor figure in the American annals of literature
CityGML Application Domain Extension (ADE): overview of developments
No full textThe Application Domain Extension (ADE) is a built-in mechanism of CityGML to augment its data model with additional concepts required by particular use cases. The goal of this paper is to provide an overview of the ADE mechanism and a literature review of developments since its introduction a decade ago. The discovery of publications found that currently there are 44 ADEs supporting a wide range of applications, but also application-agnostic purposes such as harmonisation with national geographic information standards. We hope this paper to double as a reference material for the developers of new ADEs.Urban Data Scienc
