Abstract

Motorized vehicle is a means of transportation needed to support various human activities. But on the other hand, this tool is the biggest contributor (85%) to the problem of air pollution that occurs in Indonesia. This is due to motorized vehicle exhaust emissions producing various kinds of pollutants, including hydrocarbon compounds (HC), carbon monoxide (CO), and nitrogen oxides (NOx) which are dangerous and toxic gases, and carbon dioxide (CO2) as a factor in global warming. Hazardous exhaust emissions are formed due to incomplete combustion in the working process of the motor due to a lack of oxygen gas supply. Therefore, it is necessary to find a way to overcome this impact, among others by adding additives that have a high oxygen content to the fuel. The oxygen source can be found abundantly in the blood because it contains hemoglobin, rich in oxygen. Be discovered, cow's blood from animal slaughter waste if it is directly disposed of without processing can also cause environmental pollution. Thus, this research was carried out by synthesizing additives from cow’s red blood cells mixed with methanol at a concentration of 0.1% (w/v) using a maceration time of 3 h. The use of these additives in motorized vehicle fuels resulted in reduced emissions of HC, CO, NOx, and CO2 respectively by 65.96%; 71.43%; 66.67%; and 36.15%.

Abstract

Penyebaran yang cepat dan terus meluas semenjak ditemukannya virus Severe Acute Respiratory Syndrome Coronavirus 2 atau SARS-CoV-2 pada 2019, telah memberikan dampak yang luas pada aspek kesehatan dan kesejahteraan global, khususnya Indonesia. Pencarian terapi standar melalui jalur paru seperti nebulizer, menggunakan ekstrak Asparagus diharapkan mampu menjadi alternatif dan terobosan bagi pengobatan SARS-CoV-2. Pengobatan ini merujuk pada proses penapisan antara Spike Glikoprotein (SGP) virus SARS-CoV-2 varian B.1.1.7 dengan reseptor sel manusia ACE2. Penapisan dilakukan dengan mereaksikan senyawa-senyawa yang terdapat pada ekstrak Asparagus dengan SGP virus SARS-CoV-2, sehingga infeksi dapat dicegah. Asparagus dipilih karena mengandung banyak senyawa fitokimia yang diharapkan dapat memberikan karakteristik antivirus, dan dapat menjadi acuan pengobatan COVID-19 melalui studi in silico. Didapat bahwa Dioscin merupakan senyawa yang paling kuat berinteraksi dengan SGP virus SARS-CoV-2 varian B.1.1.7 dari 67 senyawa pada ekstrak Asparagus yang dipelajari. Selain Dioscin terdapat 3 senyawa lainnya yang dapat menjadi acuan untuk pengobatan COVID-19, yakni Shatavarin IV, Aspafilioside A, dan Solasonin dengan nilai afinitas masing-masing -8.3, -8.1, -7.9, dan -7.9 kkal/mol.

Abstract

Air limbah yang berasal dari produksi minyak wangi mengandung beberapa bahan kimia yang mencemari lingkungan. Penambahan koagulan adalah metode pengolahan air limbah untuk menghilangkan material organik dan padatan tersuspensi yang menyebabkan timbulnya kebauan dan kekeruhan. Dengan menggunakan metode jar test, penambahan precipitants non-kuantitatif ke instalasi pengolahan air limbah (IPAL) dapat disesuaikan. Tujuan pengujian adalah menentukan pH dan kondisi optimum koagulan polyalumunium chloride (PAC) dalam pengujian dengan metode jar test berdasarkan pengurangan Total Suspended Solid (TSS) dalam limbah menggunakan metode statistik respon permukaan. Berdasarkan pengujian yang telah dilakukan, koagulan PAC memiliki kondisi optimum pada pH efluen sebesar 7,5 dengan dosis koagulan yang optimum sebesar 142,42 mg/l. Nilai efisiensi berdasarkan hasil pengujian parameter TSS sebesar 53,75%. Pengujian ini menunjukkan bahwa koagulan PAC memiliki efisiensi yang cukup tinggi dalam menurunkan nilai TSS. Kata kunci: TSS, jar test, koagulan, PAC, respon permukaan

Abstract

The development of innovative food packaging technologies, particularly those capable of monitoring freshness, has become increasingly important in the food industry. This research explores the development of a pH-responsive freshness sensor using polyvinyl alcohol–red cabbage (PVA/RC) nanofibers. The nanofibers are fabricated through the electrospinning technique and meticulously analyzed via scanning electron microscopy, Fourier-transform infrared (FTIR) spectroscopy, and differential scanning calorimetry (DSC). The results underscore the fine structure of the nanofiber matrix, with an average diameter of ~68 nm. FTIR analysis substantiates the presence of anthocyanin compounds from RC within the PVA/RC nanofibers, which confirms the integration of beneficial components into the nanofiber matrix. Moreover, DSC investigations reveal the outstanding thermal properties of PVA/RC, which demonstrates the resilience of the nanofibers to higher temperatures, with a melting point of ~223 °C. Notably, the PVA/RC nanofibers with a 3:1 ratio exhibit excellent thermal stability, although the color change due to pH fluctuations shifts toward transparency. This study lays down the foundation for future exploration and the potential for a diverse array of applications and material enhancements. The findings presented herein open up new opportunities for the use of PVA/RC nanofibers in the development of freshness sensors, heralding a new era in smart food packaging technology.

Abstract

The increasing volume of waste poses significant environmental and public health risks if not properly managed. The management of unprocessed waste may be initiated at the household level by applying principles of the circular economy. This study aims to investigate the integration of bioconversion technology using Black Soldier Fly (BSF) larvae with an IoT-based air quality monitoring system for tofu dregs waste management. A microcontroller-based device was developed to monitor and control humidity, carbon dioxide (CO₂), and Total Volatile Organic Compounds (TVOCs) using sensors and an adsorption-based scrubber system. The results indicate that CO₂ levels decreased from 1470–1747 ppm to 400–483 ppm, while TVOC levels were reduced from 163–346 ppb to 0–6 ppb after treatment, significantly improving air quality and minimizing odor emissions. The combination of BSF larvae-assisted bioconversion and automated emission control demonstrates a highly effective and sustainable approach to organic waste processing, reducing environmental pollution and generating valuable byproducts for economic utilization. This system offers a scalable solution for future applications in circular economy-based waste management.  In conclusion, this system offers a scalable solution for future applications in circular economy-based waste management.
