Abstract

Cayenne pepper is a perishable product. One of the damages that can cause spoilage in cayenne pepper is microorganisms. This study examines the quality change of cayenne pepper during storage. The research design employed in this study was a complete factorial randomized design with two factors: voltage levels, comprising 8,00, 9,20, and 10,40 kV, and treatment times of 20, 40, and 60 seconds. Cold plasma effectively reduced microorganisms and did not significantly affect weight loss and color value during storage. Plasma voltage levels significantly influenced hardness, total dissolved solids, and vitamin C content. The treatment with cold plasma at 9,20 kV for 40 seconds was considered the most effective in preserving chili quality. Cold plasma reduced weight loss and maintained chili color, hardness, total dissolved solids, and vitamin C content. The total plate count of cayenne pepper with cold plasma at 9,20 kV for 40 seconds is 6,55 x 105 colony/g. Cold plasma extended the shelf life of cayenne pepper for up to 12 days.

Abstract

Cumi-cumi rentan terhadap kontaminasi bakteri Vibrio parahaemolyticus dengan prevalensi 80%. Pengawetan cumi-cumi umumnya dilakukan dengan cara pengeringan setelah penggaraman air garam, dengan pertumbuhan V. parahaemolyticus tidak selalu terhenti. Pengurangan jumlah bakteri, biasanya dilakukan proses perebusan sebelum pengeringan. Penelitian ini bertujuan menentukan medan listrik dan lama waktu terbaik untuk menonaktifkan V. parahaemolyticus serta mengevaluasi efektivitas teknologi pulsed electric fields (PEF) pada cumi asin. Spesifikasi teknologi PEF yang digunakan, yaitu kuat arus 2 ampere dengan medan listrik (3,5; 7; dan 10,5 kV/cm) dan lama waktu (10, 20, dan 30 detik). Pengurangan bakteri oleh medan listrik diamati dengan penghitungan koloni, dilanjutkan dengan penghitungan sel yang mati menggunakan flow cytometer, sedangkan kerusakan bakteri diamati dengan pemindaian mikroskop elektron. Hasil penelitian menunjukkan bahwa PEF dengan intensitas tertinggi (10,5 kV/cm selama 30 detik) dapat mengurangi V. parahaemolyticus sebesar 66,12% pada tingkat kontaminasi yang tinggi (sekitar 106 CFU/g) dan 97,63% pada tingkat kontaminasi yang rendah (sekitar 102 CFU/g) pada cumi-cumi asin. Hasil ini sebanding dengan perlakuan perebusan (2 menit, 85°C). Kerusakan pada membran sel bakteri meningkat karena meningkatnya medan listrik, yang diamati dengan meningkatnya sel berpendar merah dengan flowcytometry dan kerusakan sel dengan SEM. Pulsed electric fields adalah teknologi alternatif yang menjanjikan untuk produksi cumi asin.

Abstract

The greenhouse plays a pivotal role in creating an ideal environment for hydroponic cultivation. The greenhouse has utilized rainwater and basin water as a source of raw water for hydroponic farming. Presently, the water quality of Leuwi Padjadjaran basin fails to meet the standards required for hydroponics due to its turbidity, sediment content, discoloration, pH levels exceeding 7, and low dissolved oxygen (DO) concentration of 2.2 mg/l. The micro/nanobubbles (MNBs) technology stands as a viable method for water treatment owing to its capacity to bind impurities via radical OH. The application of MNBs for the treatment of basin water involves the use of a hydrodynamic cavitation MNBs generator with a dual-chamber rotating flow nozzle. The parameters evaluated in this research encompass DO concentration, MNBs stability, microbubble size, and the visual response to MNBs application. MNBs treatment was conducted with three different gases: air, oxygen, and ozone. Microbubbles were measured using the particle image velocimetry (PIV) method. The DO concentration reaches 21.6 mg/l when employing oxygen-based MNBs. On the third day post-generation, MNBs stability still maintains DO concentrations above the initial levels. Thus it can be used as hydroponic raw water.  Keywords:  DO concentration, Greenhouse, Micro/nanobubbles, Water treatment.

Abstract

Diesel engines are known as high efficiency engines and are used in public transportation and agricultural sector. The exhaust gas produced by diesel engines is dangerous for human health. Ultra Fine Bubble (UFB) technology which is currently being developed is an emission reduction alternative that can enrich oxygen in fuel and has the potential to reduce emissions. This research was carried out to apply UFB technology to a variety of fuels and compare the emission results. This research method is data collection based on experimental tests. The types of fuel used in this research are biodiesel and biodiesel-diesel mixture. The research procedure starts from instrument preparation, fuel inflation which produces UFB fuel, fuel characteristics, instrument performance testing and data processing. The characteristic testing method follows the American Standard Testing and Materials (ASTM) and performance testing follows the ISO/IEC 17025:2017 standard. The research results show that fuel treated with ultra-fine bubbles can reduce exhaust emissions compared to fuel without UFB. CO content decreased by 608 parts per million (ppm) in the biodiesel-diesel blend and 306 ppm in biodiesel with UFB. The exhaust gas temperature becomes stable when the fuel contains bubbles and reduces NO and NOx content in emissions. Keywords: Biodiesel, Diesel engine, Fuel, Ultra fine bubble

Abstract

Hydroponic model SWU-01 is a new hydroponic system innovation that regulates watering automatically and independently by utilizing gravity and Archimedes' law. Dissolved oxygen concentration in SWU-01 is only around 3-4.2 mg/L. DO values can be increased by applying nanobubble technology. Ultrafine bubble or nanobubble is a gas bubble in a liquid that has a diameter of <200 nm. The purpose of this study was to determine the effect of nanobubble on dissolved oxygen concentration and growth of lettuce plants cultivated with SWU-01 hydroponics. The experiment used a one-factor randomized complete block design, namely intermittent administration of nanobubble for 15 min every 3 day (P1) and 7 days (P2), and without nanobubble (P0l). The results obtained based on the ANOVA test at the 5% level with the Least Significant Difference (LSD) follow-up test, namely the parameters of fresh weight and number of leaves of lettuce P1 significantly different from P0 and P2, and no significant differences were found in root length, canopy width, and plant height. The P1 treatment is more effective in increasing dissolved oxygen concentration, leaf count, and fresh weight of lettuce produced in lettuce cultivation using the SWU-01 hydroponic system. Keywords: Dissolved oxygen, Hydroponics, Lettuce, Nanobubbles, Plant growth.

Abstract

Improving the quality of B-35 biodiesel fuel is crucial, especially in distillation and flash point parameters that affect performance and safety. The objective of this study was to analyze the effect of oxygen ultrafine bubble application on the fuel characteristics of B-35 including cetane number, viscosity, density, flash point, distillation, and cloud point. Tests were conducted according to ASTM standards: D86 (distillation), D93A (flash point), D613 (cetane number), D445 (viscosity), D4052 (density), and D5773 (cloud point). The treatment was performed by injecting oxygen ultrafine bubble at a rate of 1, 3, and 5 l/min into 1.5 liters of fuel for 10–60 minutes. The results showed the highest distillation temperature of 339.7 °C at 1 l/min and 10 minutes, while the lowest temperature of 330.9 °C was achieved at 5 L/min and 60 minutes (control: 341.6 °C). The highest flash point of 72 °C occurred in the low oxygen injection rate and short duration, while the lowest was 64.5 °C in the high rate and long duration. The treatment increased cetane number from 58.6 to 60.8. The decrease in viscosity and density was insignificant but remained within standard limits. The cloud point decreased from 7.1 °C to 5 °C. UFB oxygen addition shows significant potential in improving the quality and combustion efficiency of B-35 fuel
