RANCANG BANGUN OTOMATISASI PEMILAH TEMBAKAU BERDASARKAN KELEMBABAN BERBASIS MIKROKONTROLER ATMEGA16
Tobacco is considered as one of the indonesia’s main commodities which is has a significant contribution in the national’s economic condition. Mostly production of tobacco leaf used for domestic cigarette production and export purposes. The regulation states that the tobacco moisture conditions have a very important role in a cigarette production activity. Industrial process control system in the modern era is usually refers to the automation system controller, where the role of man is no longer dominant . The automation system has many functions one of them as the tobacco moisture sorter which runs automatically .
The program was created by the tobacco sorting CodeVisionAVR to operate the system. Programs that have been saved then transfered to the ATmega16 Microcontroller hardware, with the hope of operation can succeed. This sorting using conveyor controller in an automated process.
Based on the experimental results of the tool shows the system is running successfully. This process is due to the level of humidity on the sensor electrode when the humidity is at a value of humidity 10-20 % then passes dc motor turns on and when the humidity is beyond the value of moisture 10-20 % then reject the motor on

Dengue fever is one of the main public health problems in Indonesia. The purpose of this research is to know the endemic area of dengue fever by using AHP and SMARTER method. AHP method is used to define the priority criteria, and SMARTER method is used to determine the final weight of criteria based on Rank Order Centroid (ROC) calculation. The result of research using AHP and SMARTER method get the rank order. The alternative ranks are rank 1 with the highest weight of 0.572 is Tembalang subdistrict. The lowest weight of 0.367 is Tugu and Mijen subdistricts. Alternatives with the highest Weight become the first priority in obtaining policies to cope with dengue cases. After that, followed by the rank order below because priority to tackle dengue fever case is done based on the order of ranking of each alternative. In addition, humidity criteria is very influential on the determination of dengue endemic areas with the highest weight criterion 0.46. Keywords—AHP, SMARTER, dengue feve

The analysis used in dealing with maternal mortality factors in the postpartum period can be used as a reference for preventing maternal death in the postpartum period. Appropriate analysis is needed to reduce maternal mortality rates in the postpartum period. This study uses multinomial logistic regression to analyze the data of mothers dying in the postpartum period based on the main variables causing maternal death. Multinomial logistic regression process is carried out by looking at data records of variables that influence maternal mortality. In the first experiment using data from midwife visits for seven days, the results of the multinomial logistic regression process with the highest maternal mortality occurred on the fourth day with the variable anogenital reaching a percentage of 32,4% of the causes of maternal death. Multinomial logistic regression processes are combined with cloud computing technology so that stored data is safer and can be used together.
