Abstract

This study investigates the effectiveness of ZnAl-LDH modified with polyoxometalate (POM) as an adsorbent material in the competitive adsorption of heavy metal ions Cr(VI) and Fe(II). The material was synthesized using the co-precipitation method, resulting in ZnAl-LDH@POM with enhanced interlayer spacing, a specific surface area 14 times more significant, and increased surface-active sites. Characterization using XRD, FT-IR, and BET confirmed the successful structural modification and improved adsorption properties. Kinetic studies revealed that adsorption followed a pseudo-second order kinetic model, achieving maximum efficiency within 50 minutes. Isothermal analysis demonstrated maximum adsorption capacities (???????????????? ) of 92.95 mg/g for Fe(II) and 44.44 mg/g for Cr(VI). These findings highlight the potential of ZnAl-LDH@POM as an effective adsorbent for treating heavy metal-contaminated wastewater.

Abstract

Penggunaan teknologi seperti ChatGPT semakin meluas di kalangan mahasiswa, yang memanfaatkan platform ini untuk berbagai keperluan, mulai dari pencarian informasi akademik hingga interaksi sosial. Namun, meskipun teknologi ini memberikan berbagai kemudahan, ada beberapa masalah yang sering dikeluhkan oleh pengguna. Ketidakkonsistenan dan ketidakakuratan jawaban yang diberikan oleh ChatGPT, serta lag yang sering terjadi saat menggunakan aplikasi, dapat mengurangi tingkat kepercayaan dan kepuasan pengguna. Oleh karena itu, penting untuk memahami lebih lanjut mengenai pengalaman pengguna, terutama di kalangan mahasiswa. Penelitian ini menggunakan metode User Experience Questionnaire (UEQ) untuk mengevaluasi berbagai aspek dari pengalaman pengguna. UEQ adalah metode yang menilai pengalaman pengguna melalui enam skala: daya tarik, kejelasan, efisiensi, ketepatan, stimulasi, dan kebaruan. Berdasarkan analisis data dari 153 responden, diketahui bahwa benchmark nilai untuk setiap aspek UEQ menunjukkan bahwa daya tarik (1,79), kejelasan (1,85), efisiensi (1,59), dan stimulasi (1,59) berada dalam kategori baik. Aspek ketepatan (1,30) berada di atas rata-rata, sementara kebaruan (0,23) berada di bawah rata-rata.

Abstract

This study explores the effect of hydrogen flow rate and humidifier temperature on the performance of the Membrane Electrode Assembly (MEA) using Ti-Co/C catalyst at the cathode and Pt/C at the anode in a single-cell Proton Exchange Membrane Fuel Cell (PEMFC). MEAs were fabricated by the spraying method and characterized using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) to determine their electrochemical surface area (ECSA) and conductivity. The results showed that the optimized ECSA value reached 8.38 cm2/g, and the electrical conductivity was 3.76 × 10-8 S/cm. The best performance was achieved at a hydrogen flow rate of 100 mL/min and room temperature humidification. Under the hydrogen flow rate test, the maximum power density reached 0.364 mW/cm2, while in the humidifier temperature variation, a maximum power density of 0.375 mW/cm2  was obtained at a current density 2.4 mA/cm2. These findings suggest that Ti-Co/C is a promising low-cost catalyst alternative to Pt and that operational conditions play a critical role in MEA performance

Abstract

Dharmais Cancer Hospital as a health service facility that is experienced in its field, of course, has human resources which are important, so to support employee performance in terms of employee rights such as employee leave, media is needed that really supports employee needs. Through the employee support system, namely the Employee Information System (SIMPEG) application, several problems were found in terms of appearance and the proposal process as well as the leave recapitulation process which did not exist in the previous SIMPEG application. From the problems found in the Personnel Information System (SIMPEG), a User Centered Design (UCD) method is offered which places the Personnel Information System (SIMPEG) users as the main consideration for building a new system. In the design process there are three steps that are carried out starting from the initial stage, the development stage and the final stage, where at the initial stage testing is carried out using a questionnaire, the average result is 53 which means OK but still low or not good, after the development of the system is carried out and the distribution of questionnaires was carried out again, the results were 71, which means Good. With the design of a Personnel Information System (SIMPEG) using the User Centered Design (UCD) method, it produces a new User Interface (UI) and User Experience (UX) design for the Personnel Information System (SIMPEG), which consists of a forgot password menu feature, leave recap and display easier to use for employees.

Abstract

Layered Double Hydroxides (LDHs) are a class of anionic clays known for their tunable structure, high surface area, and versatile ion exchange capabilities, making them highly attractive for environmental remediation. This critical review explores the uniqueness of LDH materials by examining recent advancements in their synthesis methods, structural and physicochemical properties, and the development of LDH-based composites. Various synthesis approaches including co-precipitation, hydrothermal, and mechanochemical methods are evaluated in relation to their influence on LDH morphology, stability, and functionality. The review also highlights the integration of LDHs with other materials such as metal oxides, carbon-based supports, and metal organic frameworks (MOFs), which enhance their photocatalytic and adsorptive performances. Special attention is given to the mechanisms underlying pollutant removal, including ion exchange, surface complexation, and photocatalytic degradation. Comparative analysis of different modifications reveals trends in application performance and identifies current challenges that must be addressed to optimize LDHs for large-scale and multi-functional environmental applications. This review provides critical insight into the future potential of LDH materials as sustainable and efficient solutions for water and wastewater treatment.
