The use of data that has long stored in the information system can be utilized to know information that supports decision-making activities. One of them is sales transaction data. During this time, the case of sales transaction data is rarely analyzed to be taken into consideration when taking a decision, such as analyzing the transaction data. The prediction analysis of the transaction should analyze the inflation factors that affect earnings. It is predicted that inflation will lead to an increase in the price of basic necessities which can also lead to employers tend to raise the price of products to be sold. Therefore, this research focuses to analyze sales transaction data at a restaurant. Where the data used is data that has been stored for 3 years within the period 2015-2017. The purpose of this study is to determine the quality comparison of sales predictions of sales between years with regard to inflation based on changes in selling prices. The result of the study is known that the prediction of goods sold with actual data in the following year is quite significant and the prediction of income is not affected by the inflation based on price comparison.

The success of the implementation of smart villages is based on the success of the village in carrying out digital transformation with Information and Communication Technology (ICT) as the driver. As a result, villages need an ICT development center which is better known as telecentre. Telecentres contribute to the social and economic development of villages with ICT as the key. In Indonesia, the establishment of telecentres is increasingly prevalent, but until now it was felt that it still did not show its success. The difficulties that arise are, constraints on information and financial management to pay for connectivity, equipment maintenance and telecentre staff salaries. The purpose of this study is to provide a telecentre development model in the form of a Village-Owned Enterprise based on hybrid organizational theory. This research approach was carried out qualitatively with a case study of Lamahu Village, Bone Bolango, Gorontalo. The process of collecting data through interviews, and the results of interviews were analyzed by interpretation into hybrid organizational theory. The results showed that the telecentre development needs to review 3 aspects, namely (1) the establishment of telecentres must have a mission as a social enterprise engaged in the implementation of ICT-based appropriate technology, (2) telecentres in the form of a legal entities Village Owned Enterprise so that they have the opportunity to obtain financial resources from external (CSR) and internal (village funds) and finally (3) telecentre human resources must involve the village community from origin so that they can help the effectiveness of interaction and ensure the sustainability of ICT adoption.
智慧村能否成功实施，取决于村庄能否成功开展以信息通信技术(ICT)为驱动的数字化转型。因此，村庄需要一个信息通信技术发展中心，也就是更广为人知的电信中心。电信中心以信息通信技术为关键，促进农村的社会和经济发展。在印度尼西亚，建立远程中心的情况日益普遍，但直到现在人们仍然认为它没有显示出成功。出现的困难是，信息和财务管理在支付连接、设备维护和电信中心工作人员工资方面受到限制。本研究的目的是提供一个基于混合组织理论的村办企业形式的电信中心发展模型。本研究方法以Gorontalo Bone Bolango的Lamahu村为例进行了定性研究。通过访谈收集数据的过程，并将访谈结果解释为混合组织理论进行分析。研究结果表明，远程中心的发展需要审视三个方面，即(1)建立远程中心必须具有作为社会企业从事基于ict的适当技术的实施的使命;(2)远程中心以法律实体的形式出现，这样他们就有机会从外部(企业社会责任)和内部(村庄资金)获得财政资源;最后(3)远程中心的人力资源必须从源头上让村庄社区参与进来，这样他们才能帮助互动的有效性，并确保ICT采用的可持续性。

As a result, villages need an ICT development center which is better known as telecentre. Telecentres contribute to the social and economic development of villages with ICT as the key. In Indonesia, the establishment of telecentres is increasingly prevalent, but until now it was felt that it still did not show its success. The difficulties that arise are, constraints on information and financial management to pay for connectivity, equipment maintenance and telecentre staff salaries. The purpose of this study is to provide a telecentre development model in the form of a Village-Owned Enterprise based on hybrid organizational theory. This research approach was carried out qualitatively with a case study of Lamahu Village, Bone Bolango, Gorontalo. The process of collecting data through interviews, and the results of interviews were analyzed by interpretation into hybrid organizational theory. The results showed that the telecentre development needs to review 3 aspects, namely (1) the establishment of telecentres must have a mission as a social enterprise engaged in the implementation of ICT-based appropriate technology, (2) telecentres in the form of a legal entities Village Owned Enterprise so that they have the opportunity to obtain financial resources from external (CSR) and internal (village funds) and finally (3) telecentre human resources must involve the village community from origin so that they can help the effectiveness of interaction and ensure the sustainability of ICT adoption.","PeriodicalId":33722,"journal":{"name":"Fountain of Informatics Journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44810671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
UGD adalah unit yang memberikan tindakan medis yang dibutuhkan korban / pasien gawat darurat dalam waktu segera untuk menyelamatkan nyawa atau mencegah kecacatan. Rumah Sakit Bakti Timah Pangkalpinang sebagai salah satu rumah sakit kelas c yang ada di Ibukota Provinsi Kep.Bangka Belitung, mempunyai satu Unit Gawat Darurat yang melayani pasien dari berbagai daerah di Provinsi Bangka Belitung. Saat ini dengan semakin banyaknya pasien yang membutuhkan tindakan medis segera, maka pelayanan administrasi medis di UGD seringkali berebut waktu untuk diselesaikan. Agar fokus pelayanan medis lebih besar pada penanganan pasien gawat darurat, maka pelayanan administrasi dapat diselesaikan dengan menggunakan sistem berbasis web. Pegembangan sistem registrasi pasien UGD berbasis web di Rumah Sakit Bakti Timah Pangkalpinang ini dilakukan dengan tujuan meringankan tugas administrasi rekam medis pasien gawat darurat di UGD, baik itu pasien akan dirawat jalan ataupun harus di rawat inap. Pegembangan sistem registrasi pasien UGD berbasis web ini dilakukan dengan metode Object Oriented Analysis and Design (OOAD) dan digambarkan dengan beberapa diagram dalam bahasa Unified Modelling Language (UML). Sistem registrasi pasien UGD berbasis web ini membantu Petugas UGD untuk mendata pasien, menelusuri rekam medis, mempercepat verifikasi data diagnosa dari Dokter UGD, dan juga membantu pasien UGD untuk menyelesaikan administrasi rawat jalan maupun rawat inap.

In most organizations, candid moments on held events should be captured as images for administrative purposes. For instance, if an event is sponsored by third parties, it is necessary to send some images capturing moments on that event to them. However, human resources are required to capture such images, resulting additional operational cost. This paper proposes a method to capture candid moments without human intervention. Unique to this method, daily device (i.e., mobile phone) is used to replace human resource with the help of a phone holder and a dedicated mobile application. Prior capturing images, given mobile application should be installed to the mobile phone and such phone should be attached to the phone holder that is aimed at event area. Candid images can be then automatically collected by running installed mobile application. According to our evaluation, such method can replace human resource for capturing candid moments using daily device. Further, it is more efficient than video recording (i.e., an alternative to capture candid moments) in terms of used battery power and memory.
