Abstract

The interaction between the addition of soybean oil and phycocyanin extract on the protein, fat, and solid non-fat content of pasteurized milk after a one-week storage period is highly important to investigate. Soybean oil is used to improve the quality of pasteurized milk, particularly its chemical quality, consisting of fat, protein, and Solid Non-Fat (SNF). Phycocyanin extract provides a source of protein, whereas soybean oil contains healthy fatty acids. Before the fresh milk is pasteurized, soybean oil and phycocyanin are added. The LTLT (Low Temperature Long Time) technique was used to pasteurize the milk at 63 °C for 30 minutes. After the pasteurization procedure was completed, the milk samples were refrigerated for one week at a temperature of 4 °C. Following the storage period, the chemical composition of pasteurized milk is examined. With the addition of soybean oil and phycocyanin extract, the protein content of milk rose, as shown by the findings. The sample T1 with a concentration of 0.45% soybean oil and 0.50% phycocyanin extract had the greatest amount of protein (3.58). The sample T2 with 0.45% soybean oil concentration and phycocyanin extract (1%) had the greatest fat content (6.4%). Adding soybean oil and phycocyanin extract enhanced the total SNF concentration. On the basis of the study conducted, it can be concluded that the addition of soybean oil and phycocyanin extract to pasteurized milk has an influence and interaction on the milk's protein, fat, and SNF content. The addition of soybean oil and phycocyanin extract to pasteurized milk held for one week may boost protein, fat, and SNF concentrations.

Abstract

Indonesia and Malaysia are recognized as the world's leading producers of palm oil. Along with the growth of the palm oil industry in Indonesia, the amount of Palm Oil Mill Effluent has increased. Palm Oil Mill Effluent (POME) is a liquid byproduct of the palm oil production process. POME has been treated using aerobic and anaerobic ponds to lower Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) levels, but it still includes nutrients like as C,N,P that are beneficial to the development of microalgae. On this study, Spirulina platensis was grown in POME medium with 20%, 40%, and 60% V. concentrations. Every two days, the nutrients Urea, NaHCO3, and TSP were administered. Seven days of aeration and 24-hour lights are used throughout the cultivation phase. The results indicate that POME with a 20 % concentration is the optimal medium for plant growth. Add 25 ppm Urea, 50 ppm TSP, and 200 ppm NaHCO3 for the optimal nutritional composition. At the same treatment on various medium, the highest growth rate of Spirulina platensis is determined to be µ = 0.128% per day, with an optical density of 0.648. Carbon reductions range from 83.03 % to 84.10 %, while Nitrogen savings range from 78 % to 79.55 % when POME is used as a growing medium. This study also shown that the C, N, and P concentrations of POME fall by 93 to 98 %, 99 to 99.5 %, and 92 to 97 %, respectively.

Abstract

Food industry is one of the most crucial and rapidly growing economic sectors in Indonesia. One of the examples is the food jam industry. This industry was located in Tangerang, Indonesia. The majority of the food jam industry uses its own source of water, so this part is also important to water producers in Indonesia. Water used in the food jam industry should meet the requirements of at least drinking water quality, so the factories need to treat the water. Good quality water is water that requires good physical, chemical, and bacteriology properties. Hard water is a term known for water that contains a high concentration of minerals such as Calcium (Ca) and Mag-nesium (Mg). Moreover, water with very high degrees of hardness is harmful to health. In this study, we want to evaluate and determine the pH, total hardness, and total dissolved solids (TDS) at three different times namely morning, midday, and afternoon. The results obtained in the range of pH analysis are 6.98 to 7.99 with all cover times. The total hardness in the boiler water and the TDS are around 252.6 to 388.2 mg/L and 310 to 406 mg/L, respectively. These results indicated that it has fulfilled the requirements for total hardness values under the Minister of Health Regulations (Permenkes) No. 492/Menkes/Per/IV/2010.

Abstract

Durian peel waste (Durio zibethinus Murray) is not effectively exploited and even left to become rubbish, which pollutes the environment. The cellulose from durian peel can be used to generate absorbent activated carbon. This study improves the durian peel adsorbent for the purification of used cooking oil. Carbon activation expands the pores of activated carbon, increasing its surface area and adsorption capacities for purifying spent cooking oil. The best conditions for producing adsorbents from durian peel were identified by adjusting the carbonization period between 300, 400, and 500 °C, activating the 1.25 m mesh size with HCl and KOH activators at concentrations of 3 M and 4 M, and soaking the material for 24 hours. Using 4 M HCl activator, 24 hours at 400 °C, and SNI 06-3730- 1995 criteria, the ideal conditions for activating durian peel activated carbon in the purification of wasted cooking oil were achieved. SEM at 1000-fold magnification (1.357 mm) confirmed an even surface and successful absorption. Durian peel adsorption in the purification of wasted cooking oil reduced peroxides (30.26%), free fatty acids (57.14%), and water content (45%), clarifying the color of leftover cooking oil.

Abstract

Cleanliness has become an integral element of daily living. Soap is often used as a cleaning agent. Soap can remove grime and microorganisms that adhere to the skin. Various types of fats or oils are often utilized as soap's primary constituents. The usage of these diverse oils alters the properties of soap, beginning with its hardness, its impact on the skin, and the resultant foam. 3 grams and 5 grams of Spirulina are added to the soap formulation. The pH test, foam height test, and organoleptic test are the test parameters. The findings demonstrated that the pH of each solid soap preparation was nine, which was in agreement with national standard criteria. The foam stability formed was 75% and 25%, and that the soap formulation maintained its color, shape, and odor for a period of ten days during storage. This research concludes that Spirulina platensis can be made into a solid soap formulation. The effects of the addition of Spirulina to solid soap include a light green color, a solid shape or solid texture, and a distinct perfume of essential tea tree oil, as well as the production of quite a bit of foam and a little coarseness.

Abstract

Smaller size plastics known as microplastics are harmful for marine biota as well as humans. One of the common methods for the removal of microplastics from water is coagulation. Chicken eggshells and chitosan are two natural ingredients which contain useful content for the coagulation process. Therefore, this paper describes the effect of concentration of eggshells and chitosan as coagulants in the separation of microplastic from water using RSM (Response Surface Methodology). The effect of tannic acid concentration as coagulation aid was also analyzed in this paper. The coagulants were varied with concentration of 1.5-8.5 g/100 mL and tannic acid concentration was 3-17 mg/100 mL. The result of this study showed coagulation with the highest efficiency occurred when 8.5 g/100 mL of chicken eggshell coagulant (89.14%) and 10 g/100 mL chitosan coagulant (75.67%) was added. Optimum operation occurred after the addition of coagulant aid in the amount of 7 mg/100 mL with chicken eggshell and 15 mg/100 mL with chitosan.

Abstract

The study focuses on malnutrition. Dietary intake influences malnutrition. Indonesians choose dry noodles due of their portability. Dry noodles often include more carbohydrates than protein; consequently, the addition of Spirulina platensis may increase their protein level while de-creasing their carbohydrate load. This research evaluated the levels of protein, fat, water, and ash in dry noodles before and after supplementation with spirulina platensis. 1% and 2% of the fixed variable weight of Spirulina platensis were used. Included in analyses are protein, fat, water, and ash. Variation I (1%) results protein of 15.79%, whereas Variation II (2%) has 28.21%. Variation I (1%) have 13.07% moisture, whereas Variation II (2%) has 13,15%. Variation I (1%) contain 0.233% fat compared to variation II (2%) of 0.223%. Variation I (1%) had 1.445% ash content, whereas Variation II (2%), contained 2% ash. The nutritional value of Grade II or dried noodles with Spirulina platensis conforms to Indonesian National Standard 8217-2015. Spirulina platensis increases the pro-tein content of dry noodles when added. According to SNI 8217-2015 grade II, the addition of spir-ulina to dried noodles improved their protein, water, ash, and fat content. The nutritious content of dried noodles was improved by the inclusion of Spirulina platensis.
