Abstract

Hepatitis is an infectious disease which is a public health problem that affects morbidity, mortality, public health status, life expectancy, and other socio-economic impacts. Hepatitis is inflammation of the liver that can increase into liver cancer. The most common causes of hepatitis are those caused by hepatitis B and C viruses. Previous research used the data mining classification method C.45 algorithm and showed an accuracy rate of 77.29%. The purpose of this study is to improve the accuracy of the C.45 algorithm by optimization using genetic algorithm. The results of this further research are the decision tree and an increase in the accuracy rate of 12.42% from 77.29% to 89.71%.

Abstract

The growth and era of information, communication and technology have changed and it has benefits in various sectors, one of them is the economy aspect. The current sales system has been moved from conventional sales into online sales by utilizing technology as a media for sales transactions. Then, one of them is the presence of e-commerce websites and e-marketplaces. The concept of e-marketplaces is a place where buyers and sellers meet, then they make online buying and selling transactions. However, there are still many plantations whose agricultural products have not been reached to be implemented by the marketplace. This problem is based on the cultural factors; it is called through the broker. Also, as well as the lack of education of farmers. The purpose of this study is to design the e-marketplace for farmers, especially in the Bugis Village. The user-centered method is applied where the approach is centered on users, then both consumers and partners. The website-designed is made by looking at the needs of the user side. This e-marketplaces can also be an education for businesses in the field of agricultural products. It is also to be involved in technological advancements by becoming partners in the e-marketplaces, so that they are able to market their products through online system. In addition, to minimize the use of agricultural products by broker, too. The results of this study are e-marketplace is able to provide convenient websites for users in conducting transactions by using gadgets to access agricultural products. This e-marketplaces also supports the promotion of Go Green, which has begun to implement a healthy lifestyle; by starting to consume a lot of vegetables. So, people will easily get best quality of agricultural products from farmers.

Abstract

The basic necessities of human life besides clothing and food are boards or what is commonly known as a house. House made human as a shelter for the survival of life. Therefore, no doubt everyone wants a comfortable and safe house. If there is damage to the house, renovations or repairs must be done so that its function is still good and can continue to support a good life. PT. Alfa Goldland Realty is an estate management office that does business in the area of ​​integrated residential area providers. One of the activities carried out is to serve the application for building renovation permits. In its implementation before the house renovation is carried out, consumers must submit a renovation permit to the office of the manager. Licensing is one of the important aspects in public services and the regulation and control of the process that will be carried out. Constraints experienced by PT. Alfa Goldland Realty in the licensing service for submitting renovations is a lengthy, time-consuming procedure for one customer, giving rise to an image of inadequate service. Currently the staff handling the licensing process is still limited and inadequate with the many requests for renovation from consumers. Using the paper as a media in the renovation permit process makes the process less effective and efficient. The low quality of service that currently drives PT. Alfa Goldland Realty must immediately improve the quality of its services. The solution needed to PT. Alfa Goldland Realty is the implementation of information systems with the User Centered Design (UCD) method. This method is used for the design of information systems that are seen from the user or user side, so that user needs will be the basis of how the system is designed. The results of this study are web-based information systems that can be accessed by consumers and management offices for the licensing process so that the activities run more effectively and efficiently.

Abstract

Pusdiklat LPP TVRI pada awalnya bernama “TVRI Training Centre” kegiatan pendidikan dan pelatihan dimulai pada tahun 1970. Pada tahun 1970 stasiun-stasiun penyiaran tumbuh dengan pesat sehingga membutuhkan penyediaan tenaga pegawai. Dalam perkembangan secara bertahap penyelenggaraan pelatihan ditangani sendiri oleh tenaga-tenaga Indonesia. Sejalan dengan penyempurnaan struktur organisasi dan tata kerja Departemen Penerangan RI, terhitung sejak tanggal 7 Juni 1970 TVRI Training Centre diubah menjadi Balai Diklat. Dengan terbitnya PP No. 11 Tahun 2005 maka TVRI Training Centre berubah nama menjadi Pusat Pendidikan dan Pelatihan. Pusdiklat LPP TVRI setiap tahunnya mengadakan pendidikan dan pelatihan untuk para pegawai. Pusdiklat LPP TVRI dalam melakukan pendaftaran peserta diklat dengan menggunakan sistem konvensional. Untuk menghindari keperluan pencatatan dan kehilangan data maka akan dibangun sistem menggunakan metode yang terkomputerisasi. Metode pengembangan perangkat lunak yang digunakan adalah waterfall dengan metode analisanya berupa kualitatif yaitu metode analisis data tanpa menggunakan analisis statistik. Dengan dilakukannya analisis perancangan sistem informasi pendaftaran pada Pusdiklat LPP TVRI maka dampak yang diperoleh dalam penyimpanan data peserta, kesalahan dalam pencatatan dapat terhindari. Adanya sistem informasi pendaftaran calon peserta diklat berbasis online ini dapat mempermudah seluruh pegawai LPP TVRI dalam proses pendaftaran diklat melalui internet
