The implementation of E-government evaluation is already a necessity to know the level of process of governance and management of service and provide improvement suggestions for quality improvement. Evaluation of the governance and management of services at the Directorate Institutional, Directorate General of Higher Education using the COBIT 2019, by measuring the capability process level based on the design factor which recommends improvement priorities in the 11 domain COBIT 2019 and the level of user satisfaction of service applications using the E-govqual model. IT capability level assessment results have 3 levels 0 processes or no existing approaches, 6 levels 1 processes or incomplete approaches, 1 level 2 process or initial approach fulfils the intent of the practice area and 1 Process level 3 or achievement of objectives is much more organized. Service Satisfaction rate measurement get 3 criteria in Quadrant A or priority improvement, 13 criteria in quadrant B or maintained, 12 criteria in quadrant C or less priority and 3 criteria in Quadrant D or less expected. Repair recommendations are compiled based on the SWOT model, referring to COBIT 2019 and ITIL 4. The results of the recommendation include increased competency of human resources and integrate services with PDDIKTI.
Abstract-Watering plants is one of farmer's activities. Most of Indonesian farmers use traditional watering method to water plants. It causes water productivity unmanaged properly and soil moisture level can not be monitored. To resolve these problems, an automatic watering system is developed. This system uses soil moisture sensors which provide real-time data. Data from multiple sensor node will be transmitted through wireless sensor network. LED in actuator node will turn on or off based on lower and upper set point values transmitted from coordinator node. Soil moisture sensors are calibrated using groundwater level to obtain correlation between sensor and groundwater level. Delay, throughput, and packet loss ratio are measured and result 0.2 seconds, 1.6 kbps, and 1.6%, respectively. These values showed that all automatic watering system were well implemented.Intisari-Salah satu aktivitas petani adalah mengairi tanaman. Sebagian besar petani Indonesia menggunakan teknik pengairan tradisional dalam mengairi tanaman, sehingga produktivitas air tidak terkelola dengan baik dan tingkat kelembaban tanah tidak termonitor. Untuk menyelesaikan permasalahan ini, dikembangkan suatu sistem irigasi otomatis. Sistem ini menggunakan sensor kelembaban tanah. Data diperoleh dari sensor secara real time. Data nilai sensor dari beberapa node sensor dikirimkan ke node koordinator melalui wireless sensor network (WSN). LED yang ada pada node aktuator akan menyala dan mati berdasarkan nilai lower setpoint dan upper setpoint yang dikirim dari node koordinator. Sensor kelembaban tanah telah dikalibrasi dengan kadar air tanah untuk mendapatkan hubungan antara nilai sensor dan kadar air tanah. Dari pengukuran, diperoleh nilai tunda, lantasan, dan packet loss ratio, yaitu tunda 0,2 detik, lantasan 1,6 kbps, dan packet loss ratio 1,6%, yang artinya semua sistem irigasi otomatis yang telah diimplementasikan berjalan dengan baik.Kata Kunci-node, sensor, WSN, irigasi, lantasan, tunda.I. PENDAHULUAN Air konsumtif sebagian besar digunakan untuk pengairan atau irigasi. Kebutuhan air konsumtif pada tahun 2010 terbagi menjadi beberapa bagian, yaitu untuk irigasi 89%, RKI (rumah tangga, perkotaan dan industri) 4%, peternakan 0,2%, dan perikanan 7% [1]. Kebutuhan air untuk irigasi sebagian besar belum dikelola dengan teknologi sistem irigasi berbasiskan komputer untuk memudahkan pengelolaan air dan membantu memonitor kelembaban tanah. Kebutuhan air setiap tahun meningkat sedangkan pasokan air setiap tahun berkurang, sehingga perlu dicari solusi dari permasalahan tersebut. Solusinya yaitu perlu dilakukan manajemen irigasi atau sistem irigasi yang tepat [2]. Sistem irigasi digunakan untuk pengaturan penyiraman tanaman sesuai dengan kondisi tanah dan ketersediaan air irigasi. Pada dasarnya, sistem irigasi terbagi menjadi tiga sistem, yaitu irigasi permukaan (surface irrigation), irigasi curah (sprinkler irrigation), dan irigasi mikro atau irigasi tetes [3].Ketiga sistem irigasi tersebut masih belum menggunakan teknologi komputer sebagai acuan dala...
Web server clusters require a reliab le network management for increasing the quality of service (QoS). A load b alancer system installed in a software-defined network (SDN) is one method that can improve the performance and availability of web server services. SDN is a dynamic and a programmab le network management approach, and one protocol that supports it is OpenFlow. This research aims to design and analyse a model of a load b alancer on OpenFlow networks, implementing a Weighted Round Rob in (WRR) algorithm. The analysis process is conducted b y measuring the value of a QoS web server performance parameters, such as response time, throughput, HTTP success, and loss connection. The results showed the WRR algorithm can b e implemented for b alancing a network system with dynamic resource allocation. The weight workload of each service can b e ob tained from the needs and existing network resources. The performance of a load b alancer on an OpenFlow network is 57% b etter than in a traditional one for testing of response time conducted in a high connection. However, the throughput and HTTP success connection decreased b y 2% and 10%, respectively, while HTTP loss connection increased b y 49%.
<p>Weather monitoring and forecasting are very important in agricultural sectors. There are several data need to be collected in real-time to support weather monitoring and forecasting systems, such as temperature, humidity, air pressure, wind speed, wind direction, and rainfall. The purpose of this research to develop a real-time weather monitoring system using a parallel computation approach and analyze the computational performance (i.e., speed up and efficiency) using the ARIMA model. The developed system wireless has been implemented on sensor networks (WSN) platform using Arduino and Raspberry Pi devices and web-based platform for weather visualization and monitoring. The experimental data used in our research work is a set of weather data acquired and collected from January until March 2017 in Bogor area. The result of this research is that the speed up of the using eight processors computation three times faster than using a single processor, with the efficiency of 50%.</p>
