Abstract

Painting is a work of art with various strokes, textures, and color gradations so that a painting that is synonymous with beauty is created. The various paintings created have characteristics, such as the paintings by Van Gogh, which have tightly arranged strokes, creating a repetitive and patterned impression. This study classifies paintings by Van Gogh or not by using the VGG-19 and ResNet-50 feature extraction methods. The SVM method is used as a classification method with two optimizations, namely random and grid optimization in the linear kernel. The data set used consisted of 124 Van Gogh paintings and 207 paintings by other painters. The use of VGG-19 feature extraction using grid optimization has the best value of 93,28% using the use of random optimization which has a value of 92,89%. The use of ResNet-50 using grid optimization with the best value of 90,28% using the use of random optimization which has a value of 90,15%. The extraction feature of VGG-19 is better than ResNet-50 in paintings by Van Gogh or not.

Abstract

Redundancy Link merupakan upaya pencegahan permasalahan jaringan dengan menyediakan jalur cadangan terhadap jalur utama yang digunakan. Redundancy Link untuk layer 3 Network memiliki beberapa metode, salah satunya adalah Hot Standby Router Protokol (HSRP). Secara default HSRP tidak memiliki fitur Load Balancing, oleh karena itu dalam tulisan ini akan dibahas penerapan Load Balancing menggunakan beberapa Group HSRP secara manual pada empat buah VLAN. Hasil yang didapat adalah proses transisi penanganan failover dan recovery berlangsung mulus dan jarang terjadi hilangnya packet atau time out, namun terjadi peningkatan delay selama beberapa saat sebelum akhirnya kembali normal. Selain itu didapati bahwa terjadi perbedaan yang cukup signifikan antara waktu failover dan recovery yang diperlukan ketika terjadi permasalahan jaringan pada satu interface fisik dan interface dengan empat sub-interface yang mewakili empat Group HSRP untuk masing-masing VLAN. Dimana penanganan failover antara keduanya memiliki selisih waktu 6.35 detik, sedangkan waktu recovery memiliki selisih waktu sebesar 6.58 detik.

Abstract

Water quality is very important for plant’s growth and development. Some of the important part of the water qualities are TDS(Total Dissolved Solid), EC(Electrical Conductivity), pH(Acidity). Cultivation inside a greenhouse provides some benefits but also have some deficiency, such as lack of soil nutrition because most plants inside greenhouse uses non soil growing media. To overcome the deficiency, An automated and remote system is needed to ease the controlling of water quality and nutrition feeding to the plant. This study aims to create low-cost greenhouse water quality monitoring that automatically display the real time data on a website. This research is done by using an engineering design methods. This system can be integrated with auto-pot watering system . The result shows that the system can adjust the TDS and pH as programmed, which are TDS= 1000-1200, and pH =5.5-6.5(these are recommended needs for Tomato plant). The TDS sensor in this reseach have the limitation of reading 0~1500ppm.

Abstract

Single Sign-On (SSO) is a technology that can support user convenience in accessing a system. By using SSO, a user only needs to authenticate once to get access to a system. OAuth 2.0 is one of the protocols that can be implemented on the SSO system. Currently, many Application Service Providers (ASP) support the OAuth 2.0 protocol thus providing convenience in the development of a more standard SSO system. Google Identity is one of the services provided by Google that can be used to build SSO systems using the OAuth 2.0 protocol. Application of the request and response methods provided by the protocol specification OAuth 2.0 and Representational State Transfer (REST) architecture of the system implementation can also make SSO systems more secure. In its implementation, the use of an agile system development methodology with the Scrum framework is used to increase speed and flexibility. The results of this research show that the use of Google Identity, REST, and OAuth 2.0 can provide easy user access, guarantee access validity, accelerate client-server data exchange and simplify the SSO implementation process.

Abstract

Air Conditioner (AC) devices in Duta Wacana Christian University 2nd floor Agape computer laboratory are turned on in the morning and turned off in the evening manually by the computer laboratory officer every day after all the classes are over. Whereas there are sessions when laboratory rooms are not used, but the AC is still on. So, there is a waste of electricity. It wastes time and energy in vain. Therefore, the implementation of AC control and scheduling can be the solution. The implementation includes a program for PC that is used to control the AC and IR module that is attached to the computer laboratory’s AC. IR module consists of NodeMCU ESP8266 microcontroller and IR LED. All microcontrollers are connected to the internet over a WiFi network. The microcontroller substitutes conventional remote control. From the result, it can be concluded that the AC control and scheduling system is successfully implemented and worked well with good performance. After the system is implemented, computer laboratory officers no longer need to turn on and off the AC manually every day. Therefore, it can save energy and time. Besides that, waste of electrical energy can be minimized, because AC will turn off automatically when the laboratory room is not used.
