Abstract

Sistem Gerbang otomatis, atau autogate, digunakan untuk memudahkan proses pembukaan dan penutupan Gerbang. Namun, dalam penggunaannya, muncul beberapa tantangan. Salah satunya adalah keterbatasan jarak akses pada sistem kendali autogate yang hanya menggunakan remote RF. Selain itu, sistem keamanan saat Gerbang menutup masih memiliki kelemahan, yaitu risiko potensial Gerbang menabrak objek yang berada di jalurnya. Untuk mengatasi tantangan-tantangan tersebut, penelitian ini bertujuan untuk merancang sistem pengendali Gerbang geser otomatis yang mengadopsi PLC sebagai pengontrol utama. Sistem ini juga akan menambahkan akses kontrol melalui smartphone berbasiskan android yang terhubung ke jaringan internet dengan bantuan modul ESP32 serta menggunakan basis data dari Firebase. Selain itu, sensor photobeam akan dimasukkan sebagai elemen pendeteksi objek yang berada di lintasan Gerbang sebagai system pengamannya. Dari Hasil implementasi dan analisis yang telah dilakukan, alat ini berhasil beroperasi sesuai dengan desainnya. Penggunaan smartphone sebagai kendali mampu mengatasi keterbatasan jarak akses, dengan waktu respons sekitar 0,5 hingga 3 detik, bergantung pada kualitas jaringan internet. Sensor photobeam juga berhasil mendeteksi objek yang berada di lintasan Gerbang, sehingga sistem kendali dapat menghentikan dan membuka Gerbang secara otomatis ketika objek terdeteksi saat Gerbang sedang menutup.

Abstract

SDN 92 Pekanbaru berlokasi di Jl. Patin No. 80 Kelurahan Umban Sari, Kecamatan Rumbai, Kota Pekanbaru. Pengelola sekolah menghadapi permasalahan ketersediaan air bersih dan sehat sesuai persyaratan kualitas air bersih yang distandarkan PERMENKES No.416/MENKES/PER/IX/1990. Sumber air pada SDN 92 Pekanbaru diperoleh dari sumur bor, namun kondisi air yang digunakan untuk keperluan di kamar mandi siswa dan guru saat ini masih kurang sehat. Air yang digunakan mengandung besi, hal ini dapat ditunjukkan dari menempelnya karat pada bak penampung air. Solusi yang dapat ditawarkan adalah menggunakan proses penyaringan. Penyaringan dilakukan menggunakan media berpori berupa pasir atau kombinasi dari pasir aktif, zeolit, karbon aktif dan lainnya. Media tersebut ditempatkan dalam pipa fiber diameter 8 inchi. Pembuatan dan pemasangan penyaring air di SDN 92 Pekanbaru telah menghasilkan air bersih dengan kriteria tidak berbau dan tanpa melalui proses pengendapan. Air yang dihasilkan saat ini tidak berwarna dan berdasarkan hasil pengujian dengan TDS (Total Dissolved Solids) meter diketahui nilai TDS hasil penyaring bernilai 15. Kondisi ini memenuhi syarat kesehatan air bersih yang telah ditetapkan pada PERMENKES No.416/ MENKES /PER/IX/1990.

Abstract

The Indonesian government continues to strive to reduce CO2 emissions, with a target reduction of 29% by 2030. In urban areas, motor vehicles are the largest contributors to CO2 emissions, accounting for 70%. One of the steps that can be taken to reduce CO2 emissions is by using Compressed Natural Gas (CNG) as a vehicle fuel. The purpose of this writing is to study the impact of replacing Diesel Fuel with CNG on the CO2 emissions generated by transportation buses.. Based on the discussion, the CO2 emissions produced by 100 city buses (fuel consumption of 100 L/unit/day) are 26.20 tons of CO2/day, 785.96 tons of CO2/month, and 9,562.56 tons of CO2/year for 100% diesel fuel. For 100% CNG fuel, the emissions are 0.02 tons of CO2/day, 0.63 tons of CO2/month, and 7.72 tons of CO2/year. CO2 emissions are reduced by 2.61 tons of CO2/day, 78.54 tons of CO2/month, and 955.49 tons of CO2/year for every 10% reduction in diesel fuel usage. CO2 emissions can be reduced by up to 99.9% by replacing diesel fuel with CNG. The area of forest required to eliminate CO2 with 100% diesel fuel composition annually is 16.79 hectares, while with 100% CNG composition, it is only 0.01 hectares. The forest area required decreases by 1.67 hectares for every 10% reduction in diesel fuel composition.

Abstract

Carbon capture is a vital strategy for mitigating climate change by reducing industrial CO2 emissions. Adsorption technology using microporous material shows significant promise. However, significant challenges persist in developing cost-effective and sustainable adsorbents. This study addresses this issue by simultaneously enabling CO2 adsorption and plastic waste utilization through activated carbon derived from polyethylene terephthalate (PET). It was evaluated under isothermal conditions (27°C, 35°C, and 45°C) at pressures up to 3500 kPa. The maximum CO2 adsorption capacity was 0.21313 kg/kg at 27°C and 3504.39 kPa, demonstrating the effectiveness of PET-derived activated carbon in capturing CO2. The Toth isotherm model exhibited a strong fit with experimental data, with an R2 of more than 99%. The Clausius-Clapeyron equation yielded an adsorption heat of 2223.66 kJ/kg using the Toth fitting, and the Chakraborty-Saha-Koyama model yielded a heat of 2383.65 kJ/kg, confirming strong adsorption potential. These results underline PET waste as a viable precursor for sustainable carbon capture adsorbents. Furthermore, the results provide essential data for developing numerical models to optimize adsorption-based carbon capture technologies.

Abstract

To improve bio-organic-carbon quality for supercapacitors, consider using dual or more heteroatom for more profitable carbon-chain doping. Developing suitable sources and preparation strategies is challenging but essential. Herein, we introduce a potential carbon source derived from acacia plantation residues, doped with boron, oxygen, and phosphorus. The pore structure of this carbon material can be precisely tuned to exhibit a well-defined hierarchical arrangement of micro-, meso-, and macropores through a low-ratio of phosphoric acid (H?PO?) impregnation method combined with dual-environment (N2 and CO2) vertical pyrolysis in one step integrated. The resulting material displays a confirmed hierarchical morphology with a hierarchical transformation into tunnel pores, in specific surface area of 521.70 m²/g which contributed to high charge storage and deliverability. Additionally, the material contains significant levels of boron (0.93%), oxygen (9.19%), and phosphorus (0.34%), facilitating a reversible Faradic reaction in the working electrode. Consequently, optimized-electrode achieves a specific capacitance of 198 F/g at 1 A/g in H?SO? electrolyte. In a two-electrode system, records energy density of 14 Wh/kg (1 A/g) at a maximum power density of 670 W/kg (10 A/g). These findings suggest that the natural incorporation of boron, oxygen, and phosphorus enhances both the activity and the hierarchical pore structure of carbon derived from acacia plantation residues.

Abstract

The transition to renewable energy sources has become increasingly critical due to the adverse effects of greenhouse gas emissions. One alternative to reducing fossil fuel dependence is hydrogen. Hydrogen technology can be integrated into internal combustion engines without major design modifications. This study investigates the effects of HHO gas blending on engine performance under varying brake load conditions. The carburetor was modified to allow HHO gas from electrolysis to enter the combustion chamber. The results indicate that HHO blending led to a 4.9% increase in brake power, a 1.66% improvement in thermal efficiency, and a 3% reduction in brake-specific energy consumption (BSEC). Additionally, among different potassium hydroxide (KOH) concentrations, the 30% wt solution exhibited the lowest power consumption for electrolysis.
