Abstract

Sago hampas is waste from processing sago starch. Sago hampas is generally thrown away without any further treatment. Sago hampas contain nutrients that can be used as a substrate for fermentation of angkak. The study aims to determine the stability and toxicity of angkak pigment powder from sago hampas-rice flour substrate. The study used exploratory research design through experiments in the laboratory. This study used the UV-vis spectrophotometer method in observing the stability of the Angkak powder pigment and the brine shrimps method of angkak pigment powder toxicity test. The results showed that the level of solubility of angkak pigment powder will increase at higher temperatures. Stability of angkak pigment powder tends to decrease with longer heating, the higher of heating temperature and the longer of irradiation. Angkak pigment powder are more stable at neutral and alkaline pH compared with acidic pH.  And it is not toxic to experimental animals with LC50 value of angkak pigment powder of 2,897.05 ppm. The conclusion of this study is that temperature affects the intensity of the angkak pigment. Angkak is unstable along with heating time, heating temperature and longer of irradiation.

Abstract

The purpose of pasteurization of milk is to improve the quality of the milk, kill pathogenic and non-pathogenic bacteria. The heating process is carried out to eliminate pathogenic microorganisms in milk, but pathogenic microorganisms can grow again after processing and packaging milk. Based on this, it is necessary to test the safety level of pasteurized milk. An important test that needs to be carried out is the physicochemical properties. The results of testing pasteurized milk using a cold chain showed a pH of 6.7, protein content about 2.67%, and fat content about 3.37%.  The influence of pasteurized milk storage conditions on its physicochemical properties also needs to be tested. The test results showed that the acidity of pasteurized milk increased during two days of storage at 20°C from 0.142 ± 0.00119% to 0.162 ± 0.00342%, the pH was lowered by 0.068 units, the average electrical conductivity (EC) increased from 5.220±0.0397 mS/cm to 5.880±0.1006 mS/cm. Increasing temperature and storage time causes an increase in phosphate ions and lowers pH rapidly, because acidification of milk causes changes in salt balance. Physical and sensory quality tests of pasteurized milk products were also carried out to determine the effect of temperature and transportation time. The test results explained that at 72 hours of transportation with a temperature of 5oC the pH value was 6.7-6.8.  These results indicate that the pH of pasteurized milk still complies with SNI, this condition is also supported by the sensory condition which is still normal.

Abstract

Essential oils, including those used in aromatherapy, are currently in high demand as consumers increasingly prefer products made from natural ingredients. Citronella oil, when used as aromatherapy, is intended to relieve headaches, enhance breathing, and produce a warming effect upon inhalation. Aromatherapy necklaces provide a convenient and portable method for delivering the benefits of essential oils. Encapsulation technology addresses the volatility of essential oils in aromatherapy gels by creating a controlled slow-release mechanism, enabling the gradual release of essential oils over a specified period. This study aims to evaluate the characteristics of aromatherapy necklaces and assess the aroma intensity of citronella oil through sensory analysis. Sensory analysis was conducted using semi-trained and trained panelists. The aromatherapy necklace comprises a mixture of gels and emulsions containing encapsulated essential oils, formulated for immediate use. The sensory analysis results indicated that the addition of 10% essential oils yielded the highest scores for color and texture assessments (4.08 and 3.96, respectively), while the addition of 7.5% essential oils produced the highest score for aroma assessment (4.16). The aroma intensity decreased from a score of 6.00 on day 1 to 3.17 on day 7. The gradual and controlled decline in aroma intensity aligns with the intended purpose of the essential oil encapsulation process.

Abstract

Dry gambier extract obtained from gambier plants contains tannins at relatively low levels. Tannins can be obtained by extracting dry gambier using water to achieve high yields within a relatively short processing time. This study aims to analyze the interaction between extraction time and microwave power in the tannin extraction process from gambier using the microwave-assisted extraction (MAE) method to maximize tannin yield.  The research method employed was a factorial design (AxB). Factor A was extraction time, consisting of five treatments (1; 2; 3; 4; and 5 minutes) and factor B was microwave power, consisting of five variations (180W; 300W; 450W; 600W and 850W). The results showed that the gambier extraction process using MAE demonstrated an interaction between extraction time and microwave power on the yield produced, but not on the tannin content. The most optimal temperature and power that can be used is 4 minutes at 600W microwave power with a yield of 44.66%. The treatment of temperature and microwave power in the gambier extraction process showed a significant interaction with the extract yield.

Abstract

Coconut-based production generates waste such as coconut husk, which contains up to 35% lignocellulose—a valuable raw material for furfural production. This study aimed to determine the impact of coconut maturity level and coconut husk section on the lignocellulose content in coconut husk. This study used a randomized group design with two factors: coconut maturity level and coconut husk section. The variables observed were moisture, extractive, cellulose, hemicellulose, and lignin contents. Analysis of Variance (ANOVA) was performed for data analysis, followed by Duncan's Multiple Range Test (DMRT). The coconut fruits used were immature and mature ones. This study analyzed the husk at the proximal end, equator, and distal end of the coconut fruit. The results show significant effects of coconut maturity level on the chemical composition of coconut husk at the three sections of the coconut, indicating coconut husk’s potential as a raw material for furfural production.
