Hydroponic is one of the solutions of gardening methods using water as a nutrition medium. Usually, maintaining hydroponic plant quality and water nutrients are done manually and require human efforts, such as the degree of acidity or wetness (pH), TDS (Total Dissolved Solids), and nutrient temperature. With the Internet of Things technology, we can automate hydroponic control by measuring the nutrients' TDS, pH, and temperature values and controlling water nutrition by pump nutrition needs for hydroponic plants. This research uses the NFT (Nutrient Film Technique) for the hydroponic system and uses lettuce as the nutrition parameter. The lettuce parameters are pH, TDS, and Water Temperature equal to the sensor we used in the proposed IoT system. The condition has 27 classifications, and we use this classification as a reference in decision-making, using the K-Nearest Neighbor (KNN) algorithm to activate the actuator. We improve the simultaneous actuator from previous research with specified intervals and duration to achieve ideal nutritional conditions. The other improvement is that we collect more data and more testing times. The accuracy was 91.2%, with k = 3. From the evaluation results, the accuracy of KNN is quite high and has an advantage, which has better accuracy than the other algorithms and can activate actuator simultaneously. We conclude that the hydroponic nutrient automation system using the Internet of Things method is ready for real planting use with this improvement.
Pesatnya perkembangan jaringan internet tidak sebanding dengan ketersediaan alamat IPV4 yang terbatas. Kondisi ini mendorong penggunaan IPV6 perlu diterapkan dan perlu diuji integrasinya dengan IPV4. Melalui simulasi Tunneling IPV6 over IPV4 pada Routing Protokol RIPNG (Routing Information Protocol Next Generation) berdasarkan algoritma distance vector dan OSPF (Open Shortest Path First) menggunakan simulator GNS3 dapat diukur performansi integrasinya. Pada penelitian ini pengukuran parameter dapat dikatakan baik dalam hal Delay, Troughput, dan Packet Loss. Delay mendapatkan nilai 79 ms yaitu nilai kategori delay yang sangat baik (excellent) berdasarkan Sumber : ITU-T H.323 nilai delay < 150 ms. Troughput mendapatkan nilai 27,40 Bytes/s maka bisa dikatakan jaringan bekerja dengan baik, karena menurut standar TIPHON, kategori throughput yang baik berkualitas sedang yaitu nilai throughput yakni antara 25-50 Bytes/s.
Menerapkan sistem keamanan dalam jaringan LAN adalah suatu keharusan agar mendapatkan kenyamanan dalam penggunaan, salah satunya adalah keamanan server. Dengan menggunakan snort untuk mendeteksi serangan menuju ICMP, TCP dan UDP secara real time akan dikirim menuju bot telegram yang sudah di integrasikan dengan shell-bot agar bot telegram tidak hanya berguna sebagai notifikasi dari snort tetapi bisa digunakan sebagai pemblok ip saat terdeteksi adanya serangan, maka admin dapat mengetahui apa yang di lakukan attacker di dalam sebuah server. Selain itu menerapkan honeypot dapat berguna untuk mengalihkan attacker menuju server palsu yang sudah di buat menyerupai dengan server asli akan merekam semua tindakan yang di mulai dari cara masuk hingga perubahan yang di lakukan di dalam server palsu tersebut, semua rekaman yang di lakukan honeypot dapat di lihat oleh administrator melalui terminal linux di kippo.log.
Along with the development of telecommunications technology, we need a network that provides traffic services to send data to distant places quickly but does not forget about security, some solutions are the Multi Protocol Label Switching method, Virtual Private Network, and Traffic Engineering. MPLS VPN TE is a combination of several methods that can be used for this problem. In this research, simulation is carried out using GNS3 software and the results of the analysis are carried out using a Wireshark software. This scenario uses the measurement load using FTP and HTTP. The measurement parameters of QoS are transfer time, throughput, delay, and packet loss ratio. The measurement results show that QoS value for transfer time of 25 MB file is 16.94s, and transfer time for HTTP is 4.2 s. The Throughput of 25 MB file is 1.606MB/s, and throughput for HTTP is 5.6 MB/s. The Delay of 25MB file is 1.22 ms, and delay HTTP is 105.37 ms
Along with the developing and the increasing of data communication users, service providers are required to always improve the quality of their services. QoS plays an important role since it is a parameter of the quality level of a service. Pipe Tunneling technique is one of the Qos methods that will guarantee a service will have its own priority level. With the help of the MPLS-VPN protocol, addressing of the IP will be much more flexible. In this thesis the simulation was done using GNS3 software while the results of the analysis were carried out using the WireShark software. There are two scenarios done by the author. For MPLS-VPN the author simulates 2 customers between companies 1 and 2 where both companies have centers in Jakarta and branches in Surabaya. And for Tunneling, both companies want their services to be given the highest priority among other services. From this scenario it can be obtained that with the presence of VRF on the network if there is the same network usage there will be no overlaps of IP. A service will have its own priority level according to the needs and requests. The results of the analysis are more focused on QoS, especially delay and throughput. From the results it shows that MPLS-VPN with Tunneling Pipe Mode integration is able to keep good QoS value. This can be seen from the average of the delay and throughput yield for Tunneling Pipe Mode that is equal to 84,51 ms and 67,858 Bytes / s.

Business continuity (going concern) is the main purpose of a business entity since the establishment of the business entity is closely related to how management can manage the business both from financial factors and non-financial factors.This research was conducted to find out what things can affect customer satisfaction in a purchase. In this research used two independent variable of service quality (X1) and customer value (X2), while customer satisfaction (Y) as dependent variable. Based on the results of the analysis, found that both independent variables have a significant and positive effect on the dependent variable. Service quality variable has positive effect 0,425 with significance level 0,003. The customer value variable has a positive effect of 0.486 with a significance level of 0.000. Adjusted R Square of the three variables is 23.7 percent, which means that the two independent variables are able to explain the variation in the dependent variable of 23.7 percent with 76.3 percent explained by other variables not used in this study.
Reduced interest in the use of city public transport services because there are still many public transport facilities that do not attach importance to the convenience of service users and the absence of alternative tariff options for long distance or short distance, so service users choose to use other transportation services that can answer their needs, such as transportation online that already exists in Purwakarta today. In this case the author is very interested in conducting research, with the title "The Influence of Perceptions of Comfort and Price Against Interest in the Use of City Public Transportation Transportation Services in Purwakarta District". The purpose of this study was to determine the effect of perceived comfort and price on the interest in using the City Public Transport Service in Purwakarta Regency.
