The development of telecommunications technology continues to increase, especially in the use of cellular communication networks. Users of cellular networks today need high-speed communication to be able to enjoy the facilities offered such as streaming video, web browsing, e-mail and others. With the current increase in user capacity, it causes a lot of interference. Therefore, the use of modulation techniques needs to be considered. To find out the proper use of modulation, in accordance with the conditions of the region and the network used, this study examines the performance of variations in modulation levels, namely QPSK, 16QAM, 64QAM and 256QAM. The parameters measured in this study include RSRP, CINR, BER, user connected and throughput. Based on the coverage by RSRP simulation results, it was found that the RSRP did not change because the power signal will always adjust to any use of the modulation level. For coverage by CINR obtained to obtain a higher rate value, a higher CINR value is needed and for coverage by BER parameters, BER does not affect the bit per symbol carried by each modulation, only affects the different types of modulation. Meanwhile, in the capacity by Throughput parameter, QPSK modulation produces the lowest average throughput value of 14.01 Mbps followed by 16QAM 21.58 Mbps 64QAM 28.6 Mbps and 256QAM 33.87 Mbps. In addition, for the capacity by user connected parameters all connected users on all modulation used will produce 100% for capacity by user connected.

This study examines whether the function f(x)=x2-9x-99 can be used as a key generator in cryptography. The quadratic function is regenerated using the fixed point iteration method into an iteration function. The distribution of digits to the output of iterative function to generate a number of chaos. Randomization testing uses run test and monobit testing. Followed by cryptographic testing to get the correlation between ciphertext and key which will be used as a decision whether the resulting key is random or not. Based on research that has been done iteration function xi = (xi-12-9xi-1-99)/9 can generate CSRPNG Chaos random numbers with the correlation level closest to the value of 0.

The Intrusion Prevention System (IPS) Snort is a server security System that can prevent attacks by examining and recording all data packets as well as recognizing packets with sensors, when the attack has been identified, IPS Snort will deny the access (block) and log of all data packets identified. However by using only IPS Snort which can only check and note the Allert attacks that are incoming in less sense to secure a server by collaborating with the other server's secure system in the sense of being able to make the network security of the server better. Honeypot Artillery chosen which works when there is a Hacker trying to penetrate through open ports can be detected as if hackers can break through the system, then Honeypot Artillery will provide information about who attackers and how the attacker could enter the Snort IPS system for later record in the database that can be viewed on the Web interface, Allert recorded on the experiment that has been done in the database as much as 9453 on TCP protocol as much as 9%, UDP as much as < 1%, and ICMP As much as 91%.

The implementation of 4G LTE network and its advantages gave us faster speed of mobile network. We need to know the performance of LTE mobile network in Sokaraja Tengah – Indonesia, which deployed by Telkomsel network provider by comparing its  RSRP, SINR, RSRQ, and throughput using drive test method of Genex Probe. Signal performance was measured by drive test dedicated mode on the streamed videos and analyzed with Genex Assistant. The result shows that generally Telkomsel’s 4G LTE network in Sokaraja Tengah has 99.7% of (-70) – (-90) dBm RSRP value, 85.09% of 1-15 SINR value, 99.23% of (-15)-0 dBm RSRQ value, average uplink 2575 kbps and downlink 1530 kbps of throughput.

When interacting with others, each person certainly needs a good skill in communication so that the purpose of socializing at school goes smoothly and is achieved. But for student with special needs seems difficult to achieve because they have obstacles or problems in communication. Therefore we need a treatment or assistance called social skills training. The purpose of the study was to determine the effectiveness of the strategy of a game technique called "Bite & Step" to improve social skills in student with special needs so that the effort to interact went smoothly and not be wrong in communicating with friends at school. As participants are groups of student with special needs who have attended elementary school. The research method used is the experimental model in a single case which is the treatment of social skills training using the game technique "Bite & Step" which is then evaluated using graph analysis. The results showed that the technical strategy of "Bite Step" has not been effective for helping to improve the social skills of children with special needs so it needs to be reviewed, evaluated, and retested again

The community's need for electricity is getting higher, so alternative energy sources such as solar heat are needed to replace energy sources from fossil fuels in meeting electricity needs. In this paper we design a two-axis solar tracker with an LDR sensor. A sun tracking system is a unit that is combined into one to control the position of the tracking device with the aim of making the surface of the solar panel module always facing the direction of sunlight. This research discusses the Prototype of the Sun Tracking System in Arduino Based Solar Power Generation Systems to get maximum solar energy. This system will make solar panels move automatically so that sunlight absorption can be maximized. The main control uses Arduino nano which gets input values ??from the LDR sensor then is processed to the output system. With the control system method can automatically be seen the difference in the results of a fixed solar panel with a solar panel with a tracker, from the comparison we get a solar panel with a tracker to get more optimal results.

Pemilu tahun 2020 merupakan salah satu rangkaian Pemilihan Umum yang akan digelar di Indonesia dengan aroma rivalitas kental setelah beberapa Pemilu yang telah berlangsung dan mengakibatkan konflik sosial. Tulisan ini berusaha memberikan deskripsi tentang rivalitas yang dapat terjadi selama Pilkada serentak 2020 dan mengambarkan akibat yang mungkin terjadi di tengah masyarakat. Kemudian tulisan ini juga berusaha memberikan sebuah deskripsi tentang pemaknaan identitas nasional Indonesia sebagai sebuah perekat. Identitas adalah sebuah penghayatan suatu individu, kelompok, atau bangsa atas dirinya yang menjadi gambaran utuh tentang dirinya. Identitas memiliki peranan sentral dalam tegaknya suatu individu dan bangsa dalam menatap masa depannya juga berdamai dengan masa lalu. Oleh karena itu, penulis berpendapat bahwa menegaskan identitas nasional merupakan bentuk reintegrasi kebangsaan yang mulai retak akibat adanya arus rivalitas dan menyongsong digelarnya Pilkada serentak 2020. Nantinya identitias juga dapat menghindarkan bangsa Indonesia dalam pusaran konflik sosial yang dapat terjadi apabila rivalitas tidak terbendung.
