Zero waste merupakan pandangan baru dalam manajemen sampah, yang mengedepankan prinsip 3R (Reuse, Reduce, dan Recycle). Prinsip ini dianggap mampu dalam menanggulangi dampak sampah pada lingkungan. Tujuan dari kegiatan ini adalah menggalakkan gerakan lingkungan bersih berdasarkan prinsip 3R. Gerakan ini diterapkan kepada siswa SMPN 2 Sekotong, Lombok Barat sebagai mitra kegiatan. Berdasarkan analisis permasalahan dengan 4 tinjauan (Surrounding, Skills, Systems, dan Supplier), permasalahan mitra adalah siswa belum memahami penanganan sampah secara mandiri di lingkungan sekolah karena belum memiliki literatur tentang penangan sampah zero waste, belum optimalnya fasilitas yang dapat digunakan dalam pengelolaan sampah secara zero waste, teknis pengelolaan sampah yang belum berjalan, serta keterampilan dalam pengelolaan sampah secara mandiri belum terlatih. Solusi yang ditawarkan menyelesaiakan permasalahan mitra terdiri dari 2 tahap, yaitu tahap direct instruction dan tahap aksi nyata gerakan bersih lingkungan. Hasil kegiatan ini adalah terbentuknya pemahaman siswa-siwa mitra dalam melaksanakan gerakan zero waste, mulai dari proses pemilahan, pengumpulan, dan pemanfaatan sampah sebagai barang yang berguna dan bernilai tambah. Hasil lainnya adalah terciptanya lingkungan yang bersih mulai dari diri mitra untuk mengurangi sampah dan memanfaatkan sampah menjadi barang ekonomis seperti pengolahan sampah plastik menjadi paving blok.

Entanglement Entropy Analysis in Dicke's Model Quantum System Rohma Yuliani; I Wayan Sudiarta; Lily Maysari Angraini

Entanglement is a property of interacting particles in a quantum system. The measure of the interaction can be known by looking for the entanglement entropy value in the system. The quantum system used in this study is the Dicke model quantum system which consists of a single-mode electromagnetic radiation field and a two-level N-atom. This study aims to determine the influence of the coupling constant on entanglement entropy and system dynamics. Simulation of system dynamics is carried out with the Quantum Toolbox in Python (QuTiP) module. The simulation results show that the coupling constant has a significant effect on the entanglement entropy value. The greater the value of the coupling constant used, the entanglement entropy value increases. In addition, there is a maximum entanglement entropy value for N greater than one. The coupling constant also affects the dynamics of the system, that is, the greater the value of the coupling constant, the more quantum states can be accessed by atoms.

This is an initial study to determine the quality of the 4.5G VoLTE signal in the area around the University of Mataram campus. This is done to get the Receive Strangth Signal Indicator (RSSI) measurement emitted by the Base Transceiver Station (BTS) owned by the Telkomsel provider at FMIPA because the VoLTE signal is unstable. The measurement method used is the drive-test. But the results are not entirely as desired. Because in some places it turns out that the quality of receiving power is very weak. Measurements obtained by drive-test carried out in the morning, afternoon, evening and night, obtained the difference in the average signal, the value of each measurement place so that it can be read more quickly converted from numbers to colors. The measurement results and theory were compared so that the RSSI level at Mataram University was obtained.

Prevention of the effects caused by natural disasters such as earthquakes and landslides requires analysis of vibration propagation. In outdoor applications, internet sources such as WIFI are not always available, so it requires alternative data communications such as nRF24l01. The system also requires a portable power source such as solar power. This research aims to develop a vibration propagation analysis system based on the nRF24l01 wireless sensor network and solar power by implementing the fuzzy rule-based regression (FRBR) algorithm. The system consists of two piezoelectric and nrf24l01 vibration sensors. The system also uses a third node equipped with temperature and soil moisture sensors, air temperature and humidity, and light intensity as environmental variables. The evaluation results show the Quality of Services (QoS) results with a throughput of 99.564%, PDR 99.675%, and a delay of 0.0073s. The Fuzzy Association Rule (FAR) extraction results yield nine rules with average support of 0.319 and confidence of 1 for vibration propagation. The availability of solar power was evaluated with an average current value of 0.250A and a voltage of 3.266V. The results of FRBR are based on the propagation of the vibration that propagated and produced a mean square error (MSE) of 0.141 and a mean absolute error (MAE) of 0.165. The correlation matrix and FAR results show that only soil moisture has a major effect on the magnitude and duration of propagation. However, other variables can regress soil moisture with MSE 0.232 and MAE 0.287.

A mixed quantum system can be represented by a density matrix. By knowing the density matrix of the system, other thermodynamic properties of the system such as Helmholtz free energy and entropy can be determined. Computation of the density matrix of a one-dimensional single-particle quantum system using the discretized path integral(DPI) method is presented. The results of the DPI method were validated using the finite difference time domain (FDTD) method for a particle in an infinite square well and harmonic oscillator potentials. The results of density matrix, Helmholtz’s free energy and entropy have shown that the DPI method produces correct numerical values compared to the FDTD results. Then, the DPI method is used in the double-well potential by giving variations in barrier potential and temperature of the system. The results show that the particle will be tunneling when the barrier potential energy is more than the kinetic energy of the particle. The particle also can tunnel easily if the system has the higher temperature.

Rain is a natural phenomenon that occurs in tropical climates during the period it occurs which is a nuisance in wireless communications. The research focus for 5G communications is ongoing to be able to overcome or mitigate rainy conditions. Rain data from satellite images is taken in the form of processed images with different color degradation. The resulting rainfall data is then converted into rain attenuation. This rain attenuation is used to predict noise interference from rain so that it can be overcome in rainy conditions. Statistical data from rain attenuation was modeled and generated numerically using ARMA which was modified to ARIMA so that observations from non-stationary to stationary. The ARIMA model value in this research is ARIMA (6,1,6).

The evolution of quantum states on photons in linear optical systems has diverse applications, ranging from fundamental to advanced quantum optics experiments for quantum information processing. This research aims to develop a simulation algorithm that focuses on modeling optical elements as a way to study the behavior of quantum states in photons. An implementation of quantum computation with linear optics has been developed as part of the simulation in this research. The configuration of the quantum network is done by modeling optical components, such as beam splitters, phase shifters, and the relationships between their components through matrix representations. The measurement results are expressed in terms of probability distributions, taking into account the effects of the optical elements through which the photons are transmitted. The simulation is capable of performing calculations for basic quantum networks with certain initial quantum states. Through this simulation, we can define quantum networks and intuitively implement quantum algorithms using simple instructions.
