The 5G NR network planning covers the types of use scenarios and applications that include Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communications (URLLC), and Massive Machine Type Communications (MTC). Regarding multicarrier modulation schemes, Orthogonal Frequency Division Multiplexing (OFDM) has become the most popular choice in previous technology, so OFDM is a strong candidate for its 5G NR technology application. However, OFDM has disadvantages such as higher PAPR and decreased bandwidth efficiency due to the addition of CP. These weaknesses can be overcome by the FBMC modulation scheme with Offset Quadrature Amplitude Modulation (OQAM) as a more efficient CP replacement for its implementation in 5G NR. This study analyzed the development of OQAM in Filter Bank multicarrier (FBMC) and compared it with using Cyclic Prefix (CP) based on OFDM using the AWGN channel. The first step of this research is to present an overview of the modulation scheme used. Next, compare the performance of FBMC-OQAM and CP-OFDM by analyzing several Bit Error Rate (BER) simulation results against the SNR value when both systems use the same simulation parameters. Based on the test results of each BER, both methods have different values, almost 2 dB for the same BER results. It indicates that the FBMC-OQAM system reached the BER value of 10-4 at SNR 15 dB. The CP-OFDM system, meanwhile, was able to achieve a BER value of 10-4 at SNR 17 dB. These results indicate that the FBMC-OQAM system is superior to CP-OFDM based on the BER values.

This study aims to describe the problems of modern society contained in the collection of short stories ‘Tawa Gadis Padang Sampah’ by Ahmad Tohari. The aim is to find out the forms of social problems in the collection of short stories ‘Tawa Gadis Padang Sampah’ by Ahmad Tohari. The data source of the research is the book collection of short stories Tawa Gadis Padang Sampah by social theme. This research is a descriptive qualitative research with a method of describing data in depth. Data is collected through the stages of reading short text carefully, classifying data, interpreting the results of data analysis, confirming the results of the analysis, and concluding the analysis results. The results of the study indicate that there are three forms of social problems of modern society that exist in the collection of short stories ‘Tawa Gadis Padang Sampah’ by Ahmad Tohari, including: poverty, environmental problems, and youth issues. Keywords: Short Stories, Social Problems, Sociology of Literature.

Aquascape merupakan sebuah seni mengatur tanaman air , ikan hias dan batu pada sebuah akuarium. Berbeda dengan akuarium pada umumnya aquascape menjadi tempat hidup dan berkembang ikan sekaligus tumbuhan air. Tumbuhan air untuk berkembang akan membutuhkan energi melalui proses fotosintesis. Proses fotosintesis tumbuhan air memerlukan pencahayaan sebagai pengganti sinar matahari. Sehingga dibuatlah suatu sistem media pengiriman data atau monitoring suhu air dan kualitas ph untuk mengetahui kualitas kesehatan aquascape tersebut. Suhu air ideal suhu air di dalam aquascape tersebut yaitu 20-28 derajat Celcius dan nilai PH yang baik adalah 6,0 – 8,0. Sistem ini berbasis mikrokontroler NodeMCU ESP8266 yang terhubung dengan sensor suhu DS18B20 dan PH Senor. Dengan dibuatnya sebuah sistem ini yang dihubungkan ke melalaui protokol MQTT, terdiri dari rangkaian alat - alat diatas diharapkan dapat melakukan pengiriman data atau monitoring suhu air dan kualitas PH secara realtime walaupun pengguna diluar rumah atau lokasi yang jauh dari aquascape tersebut, pengguna dapat memonitoring kesehatan aquascape tersebut.
