Abstract

Lapisan tipis Ba0,875Sr 0,125TiO3 di atas substrat kaca Indium Tin Oxide (ITO) dan Substrat Si (100) Tipe-P telah berhasil dibuat dengan metode Chemical Solution Deposition (CSD) dengan kelarutan 0,5 M yang dibantu dengan spin coating 3000 rpm, dan annealing pada temperatur 550 ℃ dengan kelajuan suhu 100 ℃/jam yang ditahan selama 16 jam dan suhu pendinginan hingga suhu kamar. Substrat kaca Indium Tin Oxide (ITO) dengan ketebalan kaca 1,1 mm, resistivitas ~20 ohm/sq dan resistivitas Si Tipe-P ~10 ohm/sq. Lapisan tipis ini diuji sifat optiknya menggunakan Spektrofotometer UV-Vis dengan rentang 230-850 nm dan menghasilkan celah energi sebesar 2,06 eV di atas substrat ITO dan celah energi sebesar 2,4 eV di atas substrat Si (100) Tipe-P. Analisis celah energi film tipis Ba0,875Sr 0,125TiO3 di atas substrat kaca Indium Tin Oxide (ITO) dan di atas substrat Si (100) Tipe-P sangat penting dilakukan karena film ini merupakan cikal bakal sensor cahaya.

Abstract

This research focuses on designing a control system for pesticide applicator robots on rice plants. Control is carried out via radio wave communication using a transmitter-receiver (Flysky FS-iA6 2.4 GHz). The remote can control the robot wheel (forward, backward and turn), boom sprayer (raise-fall and open-close), and spray pump. The research method is carried out using the waterfall model because it is under the needs that require a sequential flow in the process. The test results show that the use of a bevel gear gearbox can increase the torque value up to 3 times. The use of 4 electric motors further increases the stability of the robot's movement (RPM and torque) when given the maximum load of the robot. The boom sprayer successfully opens-closes and fluctuates smoothly at the optimum value of PWM 50 and voltage 2.35. The time required for the boom sprayer to open-close, and rise-fall is 30 s. The relay which functions as a switch is successfully controlled, so that the pump can be activated and deactivated in mode 2 at the input. Transmitter-receiver communication test was successfully carried out. Transmitter-receiver communication is capable of up to a distance of < 150 m. Input mode 1 on the transmitter successfully controls the boom sprayer. Input mode 2 successfully controls the motion of the wheels and pump.

Abstract

This study investigates the environmentally sustainable use of agricultural waste–based sterilization in white oyster mushroom (Pleurotus ostreatus) cultivation and its influence on mycelial optical vibrational properties. A small-scale industrial rice husk furnace was employed as an eco-friendly and low-cost sterilization system, providing an alternative to conventional fossil fuel–based energy sources. Potato Dextrose Agar (PDA) was used as the growth medium, while different sterilization levels were applied to obtain uncontaminated media and high-quality mycelial growth. Three sterilization levels were systematically analyzed using Fourier Transform Infrared (FTIR) spectroscopy to evaluate optical behavior at various cultivation stages. The optical properties of the mycelium were assessed through Longitudinal Optical (LO) and Transverse Optical (TO) vibrational modes derived from FTIR spectra. The results indicate that increasing the sterilization level leads to a consistent shift of both LO and TO modes toward higher wavenumbers, reflecting changes in molecular bonding and structural characteristics of the mycelium. Furthermore, longer boiling durations at 102 °C using the rice husk furnace resulted in higher transmittance values, attributed to the partial evaporation or reduction of certain organic compounds within the mycelium. Comparative analysis among cultivation stages shows that the planting spawn (F2) exhibits lower transmittance than the spreading spawn (F1), while the pure culture (F0) demonstrates the highest transmittance. These differences are closely related to variations in mycelial density, with F2 having the greatest mass per unit volume. Overall, the findings confirm that agricultural waste–based sterilization supports environmentally sustainable mushroom cultivation while significantly affecting the optical and structural properties of mycelium.

Abstract

This study aims to determine the reaction kinetics of the rice husk pyrolysis process by analyzing the characteristics of the Thermogravimetry Analysis (TGA) curve. Characteristics of the TGA Curve describes the process of losing mass to the temperature in the pyrolysis process with various stages of material phase changes due to the heating process. The pyrolysis process is influenced by temperature, time, and heating rate, so by analyzing the temperature, time and heating rates, the reaction kinetics will be obtained. The kinetic reaction of the pyrolysis process based on the Arrhenius equation, the speed of the decomposition reaction is influenced by changes in mass or mass fraction per unit time. Exponential factor value (A) will affect the speed of reaction of the pyrolysis process, the greater the value of A, the greater the reaction speed and vice versa. Value (A) in the pyrolysis process of HCl washed and heated rice husk, the value is smaller when compared with the value of A process of rice husk pyrolysis without washing and heating.
