Abstract

A surfactant that can be developed from palm oil is non-ionic. Diethanolamine is a nonionic surfactant based on palm oil methyl ester, which can replace the use of polyoxyethylene amine surfactant in a commercial herbicide formula that harms the environment. This research aimed to determine the physicochemical properties of diethanolamine surfactant and to study the effect of diethanolamine surfactant addition in herbicide formulation with active ingredients of isopropylamine glyphosate. This study was arranged in a complete randomized design with surfactant concentrations as treatment, consisting of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 4%, 5%, 6%, 7%, 8%, and 9% (w/w). The results showed that there was a significant effect of diethanolamine surfactant addition on the characteristics of the herbicide formulation. The concentration of 5% diethanolamine surfactant had the best character in producing herbicide with the lowest surface tension and a contact angle of 30.73 dyne/cm and 11.48°. The commercial herbicide, having a surface tension of 36.27 dyne/cm and a larger contact angle of 83.03°, was used as the comparison for the formulations. The stability of the solution was up to 100% for 5 weeks at room temperature with solubility in water of 80.60% and droplet size of 7.20 μm.

Abstract

Eco-enzymes are one of the potential sources for obtaining amylolytic bacterial isolates. The study aims to screen amylolytic bacteria from eco-enzymes, characterize semi-purification amylase, and identify amylolytic bacteria molecularly using the 16S rRNA gene. Screening for amylolytic bacteria was carried out by measuring the amylolytic index on a Nutrient agar medium containing 1% tapioca starch. The amylolytic isolate which had the highest index and was non-pathogenic was selected for the amylase characterization process. Testing of amylase activity was carried out using the Bernfeld method while the protein enzymes were measured using the Bradford method. The extracellular extract was concentrated using ammonium sulfate precipitation. PKL2 is gram-positive bacteria that was derived from eco-enzymes with the highest amylolytic indexes of 1.77, which were not pathogenic on the blood agar test. Optimum amylase was produced by PKL2 at the stationary phase at 21 h. The optimum pH and temperature of the amylase activity were observed to be 7.0 and 50°C, respectively. The amylase enzyme from PKL2 increased its purity 1.82-fold upon precipitation of ammonium sulfate at a concentration of 60%. Identification of bacteria based on molecular identification showed that PKL2 obtained was putatively identified as Bacillus amyloliquefaciens. Keywords: Amylase activity, Bacillus amyloliquefaciens, eco-enzyme, optimum pH

Abstract

Tubers, as a highly promising agricultural commodity with distinctive flavors and nutritional content, pose health challenges due to the presence of calcium oxalate. Excessive consumption can lead to mechanical disturbances in the digestive and renal tubule systems. This complicates processing techniques to ensure that tubers, before being used as raw materials in the food and other industries, do not contain calcium oxalate. The research method involves a literature review, in-depth exploration of theories and concepts, and identification of variables related to the research method and context. From the literature study, it is evident that focusing on understanding fermentation parameters, such as time, temperature, pH, and the type and concentration of microorganisms, is crucial. This information is expected to provide insights into potentially effective methods for reducing calcium oxalate content in tubers, supporting the development of safer and healthier agricultural and food processing practices.

Abstract

Sweet sorghum is the potential in Indonesia to be used as a fermentation medium for glutamic acid production. The sorghum plant resembles sugar cane which has sap in the stem. Sorghum is a plant with high sugar content and high biomass productivity. The high sugar content in sorghum sap is known from the total dissolved solids. The evaporation process on sorghum juice increases the sugar content and can inactivate microbial activity. Glutamic acid fermentation needs a substrate source derived from sugar for the growth of the producing microbes.  Therefore, this study aims to describe the sugar content in sorghum juice before and after the evaporation process so that it can be used as a substrate source for glutamic acid production. This research was carried out using the evaporation method of sorghum juice for 15 minutes at a temperature of 85 - 100 oC, so a concentrated sorghum sap was obtained. The analysis was pH, total dissolved solids (oBrix) using a refractometer, and reducing sugar content using the DNS method. The results obtained in this study indicated a significant increase in the quality and sugar content of sorghum sap with a pH of 4.81 ± 0.01 to 5.55 ± 0.03, total dissolved solids from 10.44 ± 0.09 to 34.80 ± 0.02 (oBrix), and reduced sugar content from 114.10 ± 0.45 to 271.74 ± 0.26 g/l. The sugar content allows sorghum juice to be used as raw material in industrial microbiology, especially for the production of glutamic acid.

Abstract

Amino acid protection is one of the efforts to improve livestock feed quality. Lysine is one of the limiting amino acids, which is easily degraded in the rumen, and thus requires a protection. This study aimed to determine the effect of protected lysine on cattle's digestive system and ruminal ecology in vitro. This study used encapsulation using xanthan gum and tannin (2% w/v) to protect lysine. The treatments consisted of P0 = unprotected amino acids; P1 = amino acids + 2 g xanthan gum; P2 = amino acids + 2 g tannin; P3 = amino acids + 2 g xanthan gum + 2 g tannin. Parameters observed included nutrient content, chemical activity, degradability of organic matter (OM) and crude protein (CP), and rumen fermentability (pH, N-NH3, VFA, gas kinetics, and CH4). A combination of xanthan gum and tannin coatings (P3) resulted in a higher effect (p<0.05) on rumen fermentation compared to others. The Undegraded DM and CP values in the rumen were 48% and 32%, respectively, and in the pepsin-HCl were 15% and 89%. All treatments did not change the rumen fermentability. In conclusion, protected amino acids has a effect on the cattle digestion system without disturbing the rumen ecology. Combining xanthan gum and tannin coatings provides the best results than using a single type of coating. Key words: amino acids, encapsulation, rumen fermentation, tannin, xanthan gum

Abstract

Microfiltration and ultrafiltration are used for the purification process of stevia extract to retain steviosides and remove tannins. The main objective of this study was to obtain the operating conditions for the purification process of stevia extract that resulted in the lowest stevioside rejection and highest tannin rejection. The purification process of stevia extract using microfiltration membrane was carried out at transmembrane pressure (1.20, 1.40, 1.65, 1.80, and 1.90 bar), cross flow velocity (0.04, 0.06, and 0.11 m s-1), and stevioside concentration of feed (7.12, 10.25, 14.03, and 18.47 g L-1). The stevia extract purification process used ultrafiltration membrane at transmembrane pressure (1.20, 1.40, 1.65, 1.80, and 1.90 bar), cross flow velocity (0.06, 0.09, and 0.12 m s-1), and stevioside concentration of feed (4.59 and 10.36 g L-1). The first step purification process was carried out using a microfiltration membrane and the resulting permeate was used as feed for the ultrafiltration process. The second step purification process was carried out using an ultrafiltration membrane. The best operating conditions of the microfiltration process were feed stevioside concentration of 14.03 g L-1 at a transmembrane pressure of 1.90 bar and a cross flow velocity of 0.11 m s-1 with a permeate flux of 82.90 L m-2 h-1. The best operating conditions of the ultrafiltration process used a feed stevioside concentration of 10.36 g L-1 with a permeate flux of 26.51 L m-2 h-1 at a transmembrane pressure of 1.90 bar and a cross flow velocity of 0.12 m s-1. The microfiltration and ultrafiltration processes resulted in total stevioside rejection of 59.52 % and total tannin rejection of 57.99 %.

Abstract

The quail, an endemic Indonesian poultry species, offers high nutritional value in its meat and eggs. The first 1,000 days of a child's life are crucial for optimal growth and development, with complementary foods as a key nutritional source. This study aimed to develop an instant quail-based complementary porridge enriched with various legumes. The research employed an experimental laboratory method complemented by quantitative nutritional analysis and organoleptic testing. Results indicated that the best formulation utilized soybeans, meeting the Indonesian National Standard (SNI) requirements for moisture, protein, and fat content. A 25-gram serving of the product contributes 37% of the recommended daily protein intake and provides 107 kcal of energy. The product qualifies for claims as a high-protein, high-fiber food rich in iron, vitamins, and minerals, demonstrating its potential to support infants' daily nutritional needs.
