Abstract

Leaves of citronella (Cymbopogon nardus L.) have pretty much essential oil. Essential oil from citronella leaves is generally extracted by conventional methods. Conventional method is still less effective. The problem can be overcome by using non-conventional methods in the form of UMAE (Ultrasound-Microwave Assisted Extraction). UMAE is an extraction process assisted by ultrasound and microwaves. NaCl solution can be used as a solvent in the UMAE method because NaCl has a large dielectric constant. The aim of this study was to examine the effect of extraction time and the addition of salt on the yield and color of essential oils produced using the UMAE. The extraction process begins with the raw material preparation stage, such as harvesting, size reduction, and drying. Then, pre-treatment was carried out using ultrasound for 5 minutes at 35oC with the addition of 2, 4, 6, 8, and 10% (w/v) salt. Pre-treatment results were followed by the extraction process using microwaves for 30, 45, 60, 75, and 90 minutes. The best results were obtained with the addition of 6% salt and 60 minutes of extraction time with a feed to solvent ratio of 0.1 with a yield of 1.975%. and the color is yellow.

Abstract

Ultrasound Microwave Assisted Extraction (UMAE) is an alternative to extracting clove essential oil by combining ultrasonic waves and microwaves to improve the efficiency and effectiveness of extraction. The purpose of this study is to examine the effect of microwave power and extraction time on the yield and density of clove essential oil. The cloves are reduced to a size of ± 0.5 cm and then dried using an oven for 60 minutes at a temperature of 70 °C. The pre-treatment process is carried out for 5 minutes with a temperature of 40 °C assisted by ultrasonic waves. After the pre-treatment process, the results obtained were then further extracted with microwave assistance with variable extraction times of 30, 40, 50, 60, and 70 minutes and microwave power of 150, 300, 450, and 600 Watts. The results showed that the addition of microwave power and extraction time had a significant influence on the yield value and density of clove essential oil. The best results of clove essential oil extraction using the Ultrasound Microwave Assisted Extraction method were obtained at 600-watt microwave power and at 70 minutes of extraction time with a yield value of 10.63% and a density of 1.0515 gr/ml.

Abstract

Citronella leaves are generally processed using conventional methods to obtain its essential oil. UMAE (Ultrasound-Microwave Assisted Extraction) method can be a replacement of conventional methods. UMAE is an extraction process assisted by ultrasonic waves and microwaves. NaCl solution can be used as a solvent in the UMAE method due to its large dielectric constant value. This research aimed to examinethe effect of microwave power and salt concentration on the characteristics of citronella leaf essential oil (density, refractive index, color, and solubility in alcohol). The extraction method used in this research was Ultrasound Microwave-Assisted Extraction (UMAE). The solvent and material used in this research were NaCl salt solution and Red Citronella Leaves (Cymbopogon nardus L.). The first stage carried out in this research was pre-treatment assisted by ultrasonic waves for five minutes at a temperature of 35 ᵒC, solvent concentrations of 0, 2, 4, 6, and 8% (w/v). The second stage was microwave-assisted extraction with a microwave power of 150, 300, 450, 600, and 750 Watts. The best results were produced at a concentration of 4% NaCl salt solution and 450Watt microwave power with yellow color, density value 0.8898 g/mL, refractive index 1.456, and solubility in alcohol 1:2. Overall, the quality of citronella leaves essential oil was in range of SNI 06-3953 1995. Therefore, the Red Citronella Leaves (Cymbopogon nardus L.) in the future can be considered as the alternative resource of citronella essential oil due to its good characteristics, among many varieties of citronella plants.

Abstract

The development of environmentally friendly methods for nanoparticle synthesis has gained increasing attention. Black pepper essential oil contains secondary metabolites that act as both reducing and stabilizing agents, making it a promising green alternative in silver nanoparticle (AgNP) synthesis. This study aims to investigate the effect of pH and synthesis time on the yield and characteristics of AgNP synthesized using black pepper essential oil via the sonochemical method. AgNP synthesis was carried out using the sonochemical method by adding black pepper essential oil to a silver nitrate solution. AgNP were synthesized at pH levels of 8, 9, and 10 with reaction times of 30, 60, and 90 minutes. The obtained AgNP were analyzed for yield, UV-Vis absorbance, and particle size distribution. The results demonstrated that yield increased with higher pH and longer synthesis time, reaching a maximum of 58.12% at pH 10 and 90 minutes. UV-Vis analysis confirmed the presence of AgNP with absorption peaks between 400500 nm. The particle size ranged from 9.66 to 348 nm, indicating size variability influenced by synthesis conditions. These findings highlight the potential of black pepper essential oil as a green and sustainable approach for AgNP synthesis, offering eco-friendly benefits for various applications.

Abstract

Optimization of anthocyanin pigment extraction from butterfly pea flowers (Clitoria ternatea L.) is an important focus to increase the efficiency of obtaining valuable active compounds. This study marks an initial approach in the application of Microwave-Assisted Extraction (MAE) using 0.75% aquadest-tartaric acid solvent, with the hope of producing more stable anthocyanins. The main objectives of this study were to identify the effect of the solvent-material ratio, extraction duration, and MAE power level on anthocyanin levels (mg/L) through the One-Factor-At-a-Time (OFAT) method. The results showed that the optimal treatment was obtained at condition P17, with a solvent-material ratio of 1:15, an extraction time of 15 minutes, and an MAE power of 450 watts, which produced an anthocyanin level of 33.89 ± 0.47 mg/L. These findings confirm that increasing the solvent-material ratio to the optimal point contributes to increasing anthocyanin recovery. However, excessive MAE time and power can cause pigment degradation. The optimal ratio variables were found to be in the range of 1:15 to 1:25, extraction time 9–15 minutes, and MAE power 270–450 watts. This study is expected to be the basis for further optimization using the Response Surface Methodology (RSM) method which allows for deeper analysis of the interactions between variables.

Abstract

Peningkatan kadar natrium klorida dan pengurangan impuritas air laut dapat meningkatkan kualitasnya sebagai bahan baku untuk pembuatan garam industri. Salah satu pendekatan yang digunakan dalam proses pemurnian ini adalah pemanfaatan gas karbon dioksida sebagai agen pengikat impuritas. Karbon dioksida bereaksi dengan ion–ion tertentu dalam air laut membentuk senyawa karbonat yang tidak larut, sehingga dapat dipisahkan melalui proses presipitasi. Dalam penelitian ini, parameter utama yang dibandingkan untuk menentukan efektivitas proses adalah laju alir gas karbon dioksida dan waktu kontak antara gas karbon dioksida dengan air laut. Laju alir gas karbon dioksida yang digunakan adalah 400,  500, 600, 700, dan 800 mL/menit, serta waktu kontak pada rentang 15, 20, 25, 30, dan 35 menit. Penelitian ini berhasil mengurangi kadar pengotor Ca2+ dan Mg2+ dalam air laut yang semula berturut–turut sebesar 0,12 dan 0,16% menjadi 0,0203 dan 0,0115%, serta meningkatkan kadar natrium klorida yang semula 1,88 menjadi 2,4502% dengan laju alir karbon dioksida 800 mL/menit dan waktu kontak selama 35 menit. Hasil tersebut menunjukkan bahwa semakin lama waktu kontak dan semakin besar laju alir gas karbon dioksida yang digunakan, maka kadar pengotor dalam air laut akan semakin kecil dan kadar natrium klorida akan semakin meningkat.

Abstract

Feed is the most important thing in doing a tilapia fish farming. In a feed required appropriate and balanced nutritional content so that fish growth becomes faster. Shrimp waste and tarum leaves are an alternative raw material for the manufacture of tilapia feed because they have a fairly high protein content. The purpose of this study was to examine the comparative effect of adding the percentage of tarum leaf meal and EM-4 fermented shrimp waste on water content, ash content, protein content, fat content, and crude fiber content of feed. The research method used is using the EM-4 fermentation process on shrimp waste. The variations carried out were the concentration of the addition of EM-4 (14,16,18,20, and 22 ml) and the percentage of addition of Wet Shrimp Waste (WSW) and Tarum Leaf Powder (TLP) (90%WSW + 10%TLP, 80%WSW + 20%TLP, 70%WSW + 30%TLP, 60%WSP + 40%TLP, and 50%WSW + 50%TLP). The results showed that the addition of fermented WSW EM-4 and TLP had a significant effect on the protein, fat and crude fiber content, while the water and ash content did not have a significant effect. The best tilapia feed formulation results were obtained at a ratio of 60% WSW and 40% TLP using 18 ml of EM-4 with the results obtained for water, ash, protein, fat and crude fiber content each of 7.09%. ; 12.59%; 29.98%; 7.45%; and 3.49%.

Abstract

Indonesia is one of the agricultural countries with an abundance of farm products, including bananas. The utilisation of banana peel waste has a very high value if used as a raw material for glucose production. One method used for glucose production is enzymatic hydrolysis. The objective of this study is to investigate the effect of liquefaction time and saccharification time on the rate of enzymatic hydrolysis reaction, as well as to determine the kinetic equation for the enzymatic hydrolysis synthesis of banana peel glucose. The stages of this study include the raw material preparation stage, the enzymatic hydrolysis stage, and the final content analysis stage. Glucose content analysis was performed using a portable refractometer. The Michaelis-Menten method was used to determine the reaction constant. This study was conducted with an initial substrate concentration of 30% (w/v) at liquefaction times of 80, 100, 120, 140, and 160 minutes. Additionally, saccharification times of 12, 16, 20, 24, and 28 hours were employed. The dextrin formed during liquefaction was 29.6%, 29.2%, 28.8%, 28.5%, and 27.8%, respectively. These dextrin levels were used as reactants in the saccharification process to produce glucose. The glucose formed from the hydrolysis of banana peel carbohydrates with a dextrin content of 29.6% and a saccharification time of 12 hours was 4.2%. The reaction rate equation formed from this process is   Contribution to Sustainable Development Goals (SDGs):SDG 2: Zero HungerSDG 9: Industry, Innovation, and InfrastructureSDG 12: Responsible Consumption and ProductionSDG 13: Climate Action
