Rainfall forecasting provides benefits in several sector. The pattern of rainfall intensity in the same month every year has similarities, so that modeling of fuzzy time series can be used to model rainfall pattern in a region, but the amount of rainfall in every month has a varied value which where there is too high rainfall values and too low (outlier). The value of the outlier can damage the error distribution causing the forecasting value to be not good, so it needs an outlier search method to optimize the fuzzy time series method. In this research has prposed the model used box whisker plot method to find outlier data and then compare the result fuzzy time series method with outlier data and data with outlier that have been omitted. The accuracy value is better indicated by the decrease in MAD value where the initial MAD value forecasting with outlier data is 114.39 and the predicted MAD value forecasting without outlier data is 93.85.

The security strength of key distribution of most conventional cryptography is relied on mathematical complexity and the irrational time needed to break the algorithm. But it will be ineffective if the secret key distribution procedure is weak. In 1994 Peter Shor proposed an algorithm that can factorize great integer number efficiently by using principle of quantum computer, this algorithm poses a threat to some of the conventional cryptography. Recently, Quantum Key Distribution (QKD) is drawing much attention of researcher as a solution of that problem of key distribution. Theoretically, QKD have been proven can be provide unconditionally secure communication based on quantum mechanics laws. In this article we survey the QKD protocols. Also, we present a little experiment of some QKD protocols that we discussed on this paper.

Wireless sensor networks (WSN) are commonly formed by distributed sensor nodes equipped with wireless transmitter with limited bandwidth, computation power and battery sources. WSN are generally developed for wild life, military or environmental monitoring etc. These facts have highlighted challenges to minimize energy consumption of sensor nodes while still maintaining the goal of WSN developments. In this paper, an integration of cluster-based and position based routing protocols for multi-hop scenarios is proposed. The self-organized clusters are formed periodically where decision to become cluster head (CH) is performed individually by each node. Direct long communication between selected CH to sink node is avoided to preserve energy and minimize impact of overhearing transmission. Accordingly, a multi-hop communication scheme which adopts position based routing is applied. The proposed approach has been developed and tested using wireless simulation framework. It shows that the proposed approach can increase remaining battery energy, increase packet delivery ratio and reduce the number of dead nodes in various simulation settings.

5G cellular network business is changed by the development of technology and socio economic transformation and is expected to send information quickly and support many cases from various applications. Massive Internet of Things (IoT) is one of cases on 5G network. This includes Massive Machine Type Communication (mMTC). Wireless Sensor Network (WSN) for monitoring and sensing is one of the mMTC application. Limited power of each sensor node is the constrain aspect of WSN usage. In WSN, energy efficiency becomes an important issue. Routing is a function in WSN, which consumes substantial amount of energy. One of the routing protocols that can increase the energy efficiency of WSN is Low Energy Adaptive Clustering Hierarchy (LEACH). In this paper, Base Station (BS) and High Altitude Platform (HAP) are used as sink node. Type of waveform used to support the WSN system on a 5G network is Universal Filtered Multi Carrier (UFMC). The purpose of this simulation is to compare WSN systems using BS's and HAP's. Performance indicators that we evaluated are energy consumption and channel capacity. From a series of simulations conducted, the results obtained show WSN systems using HAP's, the consumption energy are more efficient than WSN systems using BS's. Capacity channel of the WSN systems using HAP's is greater than the WSN systems using BS's. It is more efficient using HAP's as a sink node in the WSN systems.

Desktop virtualization proposed a mechanism to consolidate desktop computing resources, where the processing power was moved from user's side to centralize server's side. Many of desktop virtualization initiatives considered as fail because it run smooth during trial, but facing bottlenecks during real-life operation. Not surprising, since during trial, we dealt only with very small quantity of VMs, compared with production. Some enterprise solution with focus on storage performance has proposed full-flash storage solution, but for small to medium scale organization that had budget constrains may prefer DAS (Direct Attached Storage) or NAS (Network Access Storage). Of course DAS and NAS had limitation in performance compared with SAN, then some vendors offer server-side caching solution for virtualization that utilize RAM (Random Access Memory) or flash drive to leverage the storage performance. This experimental test was conducted to evaluate DAS and NAS from two perspectives (Performance and initial-investment cost), using IOmeter as workload simulator and benchmark tools for five storage scenarios, all configured in RAID10 and using server-side caching as storage accelerator. This experimental test also intended to answer which storage approach (between DAS and NAS) that most suitable with ABC's requirement, ABC was a university located in Jakarta. Three scenarios from DAS-based approach, labeled as SAS7.2k, SAS10k, SAS15k, and two other scenarios from NAS-based approach was labeled as NAS1-7.2k, and NAS2-7.2k. When talked about performance, we focused on three critical parameters (IOPS, bandwidth and latency). While SAS15k (DAS-based) and NAS2-7.2k (NAS-based) were the top performer from each respective category, the author found that NAS2-7.2k was the best option, it outperformed SAS15k that 9,11% higher in price. NAS2-7.2k had 108,14% higher in total IOs per second (Represent IOPS), 108,1% higher in total MBs per second (Represent bandwidth), and 107,53% lower in average IOs response time (Represent latency) when compared with SAS15k.

Uninterruptible power supply (UPS) monitoring system using message queuing telemetry transport (MQTT) protocol is a solution to solve UPS monitoring issues in a large infrastructure. This paper discusses the proof of the small size of message data by using the MQTT protocol on IoT-based communications. Based on IoT concept, the system described in this paper used Arduino microcontroller connected to the Internet via an Ethernet shield. The system used MQTT as a communication protocol that was designed for a lightweight communication. This system was intended to display UPS monitoring data in real-time on a web page stored on raspberry pi which roles as a web server, MQTT broker, MQTT subscriber and database. UPS parameter could be monitored using a web-based application. There were some differences in data obtained from sensor with the measurement results of measuring instruments specified for each parameter: the difference of input voltage was equal to 0.20%, while differences of output voltage, output power and output current reached 1.34%, 0.17% and 20%, respectively.

In this paper, we investigate the performance of a femtocell implementing sparse code multiple access (SCMA) system, which has the ability to access the wireless channel opportunistically using cognitive radio (CR) capabilities. Dynamic spectrum access (DSA) of CR enable the femtocell to works on the channels with the lowest level of interferences. The interference level of a channel which is indicated by an interference signature determine the channel usage priority level. Simulation result show degradation of bit error rate (BER) when probability of missed detection of energy detection spectrum sensing increase. It is also shown that as the decision threshold of energy detection become higher, the number of received bit error in the femtocell base station increased.
