Wireless Sensor Network (WSN) is an infrastructure consisting of a number of sensor nodes that are distributed in certain environments and coordinated using a wireless network. WSN can be implemented using the nRF24L01 module. One protocol that supports the nRF24L01 module is the RF24 protocol. But for the implementation of monitoring the vast room conditions this protocol has the disadvantage of using a single-hop mechanism. So that for a large area range, multi-hop mechanism is needed. The RF24Network protocol is a protocol designed to meet the needs of RF24-based multi-hop mechanisms, users simply build a header that contains the correct destination address and the network will forward it to the destination node. In accordance with the above problems, the authors implement sensor nodes using Arduino Nano as Microcontroller, nRF24L01 for communication media and DHT11 to acquire sensor data. From the implementation results obtained network performance for monitoring the condition of the room with the level of accuracy of data transmission and delay as follows. Single-hop data transmission mechanism without barrier distance 3-12 meters 100% accuracy, 15 meters 70%, 18 meters 40%, 21 meters 0% with a total average delay of 145 ms, with a distance barrier of 3-9 meters 100% accuracy , 12 meters 60%, 15 meters 30%, 18 meters 0% with a total average delay of 276 ms. The multi-hop mechanism of data transmission accuracy reaches 100% with average delay (1 hop without barrier 110 ms with a total distance of 24 meters, with a barrier of 270 ms with a total distance of 18 meters. 2 hops without barrier 270 ms with a total distance of 36 meters , with a 350 ms barrier with a total distance of 27 meters, 3 hops without a 280 ms barrier with a total distance of 48 meters, with a barrier of 260 ms with a total distance of 36 meters)..

The implementation of Radio Network (2G/3G/4G) in Indonesia still has many obstacles, especially for the coverage area which is still uneven. So that causes there are still many areas in Indonesia that are classified as bad spot areas, one of which is the Koto Baru Payobasung area, Payakumbuh. This is obtained from the existing simulation carried out, which obtained 2 of the 3 parameters classified in very bad conditions, namely RSRP and Throughput. To overcome this problem, the way that can be used is network optimization. This research implements Carrier Aggregation (CA) using Automatic Cell Planning (ACP) optimization technique with RSRP, SINR, and Throughput parameters. The results showed an increase in each parameter, where the ACP technique obtained an RSRP value of = -103 dBm, SINR of = 2 dB, and Throughput = 15 mbps. As for the CA technique, the RSRP value = -90 dBm, SINR = 7 dB, and Throughput = 50 mbps. These two optimization techniques show that implementing CA is more effective than the ACP technique due to the value of the optimization parameter results.

Water is a very important source of energy needed by living things. Water has the property of flowing from a higher place to a lower place. Therefore it is necessary to optimize using a water pump to drain water to the desired place according to needs. In general, pumps that are used to move water from one place to another are generally used by an electric motor to rotate the pump. In maintaining the optimal level, an electric motor capacity that is in accordance with the pump capacity is needed. Determination of this capacity is related to the amount of motor power required to drive the pump. With a good motor capacity, the efficiency of the pump can be increased. Based on the calculation of the total head in the piping system at the sandfilter tank pump, it is 18,708 m with a power of 5.06 kW and the working efficiency of the electric motor for the sandfilter tank is 67.46%.

Competition in the industrial world today requires producers to compete in providing good quality products with short production times and relatively low production costs. This relates to production machines which have an important role to produce products with good quality. PT. Voith Paper Rolls Indonesia is a service and manufacturing company engaged in roll repair and manufacture of roll cover materials. One of the production processes carried out during roll repair is the turning process which is carried out twice. In the turning process, there is often a significant time difference between the actual time and the estimated time obtained from the existing formulation. Therefore, this report will focus on efforts to improve the calculation formulation for the estimation of turning process time on lathe A on hard plain rubber roll by analyzing the effect of surface area on processing time using a simple linear regression method through the IBM SPSS application.
