Abstract

The photovoltaic process inside a solar cell can be described using the distribution of electrostatic potential in the material. In this paper, the magnitude of the electrostatic potential of the solar cell for the p-i-n junction type is analyzed as the built in potential due to the diffusion activity of electrons and holes. The magnitude of the electrostatic potential is obtained by solving the Poisson and Continuity equations, which are applied to a-Si: H based materials. The difference in built in potential at the p-i and i-n junctions is obtained as a function of the energy gap of the intrinsic layer.

Abstract

The substrate is an important factor for efficient electricity production in Microbial Fuel Cell systems. The substrate is an organic compound that promotes the growth of active microbes. The goal of this study was to investigate the effect of substrate type and concentration on the bioelectricity produced by a single-chamber MFC. Fructose and butyric acid were used as substrates and carbon felt used as an electrode. Types and variations in substrate concentration were applied to the soil media used in the MFC. After 3 weeks of incubation, the optimum power density value achieved by MFC with 90 g/L fructose substrate was 20.5 mW/m2. Whereas, MFC treated with 800 mg/L butyric acid produced a maximum power density of 19.7 mW/m2.Keywords: Substrate, Fructose, Butyric acid, Power density, Microbial Fuel Cell.

Abstract

The liquid lead corrosion is often described as a damage of the metal surface due to the high solubility of atoms of the metal that flowing into the liquid metal medium through the diffusion process. This research was conducted to examine the performance of FeNi alloys in liquid lead at various compositions, especially the metal structure conditions due to interactions between metal atoms at high temperatures. To see the performance of this FeNi alloy steel, the parameter that you want to know is the diffusion coefficient of its constituent elements. The potential used is the Lennard-Jones potential. This research uses the LAMMPS molecular dynamics simulation software. From the simulation works can be concluded that the lowest diffusion coefficient of Fe in liquid lead which produces the strongest structure is at the composition (concentration) 65% Fe and 35% Ni with related diffusion coefficient of 5.8582 x 10-12 m2/s, where at this value the corrosion of FeNi in Liquid lead can already be reduced till 77.32%.Keywords: Liquid lead corrosion, Molecular dynamics, FeNi Alloy, Composition, LAMMPS.

Abstract

An electronic system for cooking oil dielectric  constant measurement have been done. The system was employed an capacitive sensor, IC Timer 555, oscilloscope, and power supply. The cooking oil is placed in a capacitive sensor as part of unstable multivibrator IC 555 circuit. The samples(labeled and non labeled) temperature was condisioned on room temperature and at 100 ⁰C with the heated time duration of 1 hours, 2 hours, and 3 hours treatment.   The result of  the measurement shows that all sample with time duration 1 hours and 2 hours increases but with time duration 3 hours turn down.Data SDYhttps://materassomemory.org/https://visualresearchnetwork.org/https://brazoriafumc.org/https://atmamayor.com/https://viralblasts.com/Bloom ScapeRokokbetRokokbetScatter HitamRokokbethttps://press.umam.edu.my/Rokokbethttps://theusajournals.com/RokokbetShiowlaRokokbetRokokbetRokokbetRokokbetRokokbetShiowla

Abstract

The application of ceramic-based Microbial Fuel Cells (MFCs) for the treatment of tofu liquid waste presents a promising and environmentally sustainable approach. The purpose of this study was to determine the effect of adding variations in substrate concentration and to determine the effect of variations in the surface area of the electrode (anode and cathode), resulting in a maximum power density value for a period of 13 days of measurement. The initial step is measuring the voltage and current with the substrate concentration without a dilution process, then the concentration variations are carried out by dilution 10 times, 8 times, 5 times, 4 times, and 2 times on ceramics with a diameter of 8 cm. The second step is measuring the voltage and current by varying the surface area of the electrodes (cathode and anode). The results of the measurements obtained that the maximum power density value obtained was 188.23 mW/m2 without a dilution process, namely with a concentration of 3640 ppm for the third day. Meanwhile, the results of the measurement of the variation of the electrode surface area obtained a maximum power density value of 205.88 mW/m2 on the electrode surface area of 3.57 m2 for the third day. The more surface area of the electrode given at the time of measurement, the more bacteria contact the electrode, causing the resulting power density value to be even greater.

Abstract

The Faraday Effect is a magnetooptical phenomenon in physics describing the interaction of light and magnetic fields in a medium. A parameter that indicates the interaction is the Verdet constant. In this research, Verdet constant was measured on cooking oil that has been used several times. Magneto-optical properties were measured using the polarimetry method, which uses a He-Ne Laser beam with a magnetic field treatment of 50 gauss, 80 gauss and 100 gauss. The samples analyzed were bulk and non-bulk cooking oil. Repeated use of cooking oil causes a change in the polarization axis of the polarized laser. This has an impact on the Verdet constant of the material. The difference in the Verdet constant shows that the Verdet constant can be used as an indicator of cooking oil that has been used up to three times.

Abstract

Kecerdasan emosional adalah suatu suatu dimensi yang menunjukkan kemampuan manusia secara emosional dan sosial. Kecerdasan berperan membentuk kepribadian individu sehingga dapat mengenali dan mengendalikan diri, memahami emosi orang lain dan dapat berinteraksi sosial dengan sesama. Kinerja seorang perawat adalah capaian hasil pelaksanaan kegiatan yang dilakukan perawat sesuai kemampuannya berdasarkan standar asuhan keperawatan. Penelitian ini bertujuan mengetahui hubungan kecerdasan emosi dengan kinerja perawat. Rancangan penelitian menggunakan metode kuantitatif dengan pendekatan cross sectional. Populasi dalam penelitian ini, semua perawat di Fasilitas Pelayanan Kesehatan Kecamatan Rembang sebanyak 32 perawat.

Abstract

Payment for Environmental Services (PES) is an environmental service compensation activity conducted by Forest Programme IV (FP-IV), designed to be implemented in the Mamasa Sub-Watershed of the Saddang Watershed. The implementation of this PES plan will be collaborated with parties such as the Bakaru Watershed Forum, Hydroelectric power plant (PLTA), and Forest Farmer Groups (KTH) in selected villages over a 5-year contract. However, the challenge is that the target community lacks trust in PES activities and most refuse to join, making the formation of KTH Mappideceng problematic. The purpose of community service is to enhance the capacity of KTH Mappideceng based on the requirements and criteria established by the PES model scheme. The methods used include primary socialization (door-to-door) such as surveys, lectures, and discussions. The results of the community service activities in KTH Mappideceng, Betteng village, showed an increase in the number of members from 12 to 21, with 15 being new members and 6 being existing ones. After the socialization carried out by the team, enthusiasm and motivation to join increased; however, the intervention location and funding limitations were predetermined by the PES model mechanism (FP-IV).
