Abstract

PT. Firdaus Kurnia Indah is one of the traditional herbal medicine industries in Bangkalan. One of the herbal medicine products with the highest demand is rapet wangi. News about traditional herbal medicine that is added with hazardous chemicals can cause complaints that are very detrimental to health. Therefore, it is necessary to carry out material inspection and monitoring of the process of making traditional herbal medicine that is free from the dangers of chemicals. The method for identifying hazards in the production process was by using the HACCP (Hazard Critical Control Point) method. The application of HACCP in the process of making herbal rapet wangi produces critical control points (CCP) in the drying process and the printing process. In herbal rapet wangi products, it can be seen that the critical control points (CCP) are in the drying process and the printing process. In the drying process where the risk of contamination of pathogenic microbes is very high. The risk of contamination of pathogenic microbes is very high because it is feared that the microbes will not die even though they have been heated. In the process of forming herbal medicine, there is a risk of cross-contamination from workers and equipment because when forming herbal medicine it is round, does not use gloves, and does not use hair coverings.

Abstract

Coconut holds immense significance in Indonesian coastal communities, offering diverse benefits from its fruit, leaves, trunk, and roots. It plays a pivotal role in the local economy, particularly in East Java's Trenggalek region, a significant coconut producer. In 2021, Trenggalek, notably Watulimo District, contributed significantly to the national coconut production. Desiccated coconut, a vital processed product, was studied concerning temperature and adding BHT (Butylated hydroxytoluene). The research aimed to assess their impacts on desiccated coconut properties. Conducted through various tests, including yield, pH, water activity, phenol content, and organoleptic evaluations, the study utilized a Completely Randomized Design (CRD). Based on the research findings, BHT (Butylated hydroxytoluene) significantly influences the quality of desiccated coconut, with values of 0.38 for water activity response and 0.36 mgGAE/g for total phenol content response. Drying temperature treatment affects the quality parameter value, with a yield response of 65.02 %. The pH value of desiccated coconut remains within the normal range, ranging from 6.33 to 6.44. The optimal treatment is found at a temperature of 80°C and the addition of 0.347 g of BHT to produce the best medium-grade desiccated coconut.

Abstract

Repeated cooking oil (used cooking oil) can cause the lubricant to smoke or foam when frying and leave a brown color. One of the factors that influences oil damage is the auto-oxidation process. The reactions during the auto-oxidation process in oil will form peroxide compounds. To reduce the peroxide value in used cooking oil, a substance is needed that prevents oxidation, namely an antioxidant. This research aimed to determine the antioxidant effect of mangosteen peel powder on the peroxide value and acid value of used cooking oil. The study used a non-factorial wholly randomized design. The research results obtained showed that mangosteen peel powder contained an antioxidant activity of 36.97% RSA, and the addition of mangosteen peel powder significantly reduced the peroxide value and acid value of used cooking oil. In conclusion, the addition of 12% mangosteen peel powder was able to improve the quality of used cooking oil by reducing the peroxide value (7.02 to 4.39 mg O2/100g) and acid value (1.08 to 0.73 mg KOH/g)

Abstract

Cell immobilisation is a process to stop the movement of cells at a certain place in a reaction chamber that is used as a catalyst. Cell immobilisation is commonly used for various biotechnology applications, one of which is ethanol fermentation because it has the advantage of being more efficient and effective compared to using free culture. Yeast isolate IS258 is a superior isolate taken from the arak industry in Karangasem Bali which function as bioethanol fermentation agent. The immobilisation of IS258 yeast cells was made using sodium alginate which functions as an entrapment media. The calcium alginate matrix of IS258 was then used for ethanol fermentation of coconut sap analogue to replace the need of new starter. This study aimed to determine the optimal total alginate volume and dextrose concentration using immobilised IS258 yeast for bioethanol fermentation of coconut sap analogue using Response Surface Methodology (RSM). In this study, 13 variations of total volume of alginate with immobilised IS258 yeast within and dextrose concentration in coconut sap analogue media. The results showed that dextrose as a substrate was more influential than the alginate-IS258 matrix on the ethanol produced. The highest total ethanol was obtained from the treatment with matrix volume concentration of 25% (v/v) and dextrose concentration of 15% (w/v) with an average total ethanol of 93.8 ml. The D-optimally test results show that the total matrix volume concentration value has an optimal point of 19% and dextrose concentration of 24% and is expected to produce more than 80 ml of ethanol. The use of alginate-IS258 matrix has been used in ethanol fermentation for 3 times distillation for more than 25 days continuously, the results show that the ethanol produced continues to increase and the fermentation time decreases.

Abstract

Honey is a popular healthy food that also serves as medicine. Stingless bee honey gained interest compared to regular honey due to its health benefits. This study aimed to investigate the potential health benefits of honey produced by stingless bees Heterotrigona itama and Tetragonula laeviceps, namely phenolic content, flavonoid content, antioxidant capacity, and antimicrobial activity. The research was conducted using complete randomized experimental design by two separate replications. The result shows both honeys have a pH value ranging from 3.16 to 3.43. The antioxidant capacity, total phenolic compounds, and total flavonoid compounds of both honeys were not different (p≥ 0.05). The antioxidant capacity of honey produced by Heterotrigona itama and Tetragonula laeviceps was 593 mg TE/100 and 581.58 mg TE/100 g, respectively. The total phenolic compound was in the range of 839.26-1242 mg GAE/kg, while total flavonoid was in the range 126 – 179 mg QE/ of) However, H.itama honey had the highest inhibition against Gram-positive Streptococcus mutans, while T.laeviceps had the highest inhibition against Gram-negative Pseudomonas aeruginosa. The types of local vegetation might relate to phytochemical compounds in honey. This study gave insight into another possible antibacterial compound in stingless bee honey, namely, a bioactive peptide that might act differently on microorganisms.

Abstract

The study regarding the extraction of bioactive compounds from natural sources such as phenolics, flavonoids, and carotenoids has received significant attention, because these bioactive compounds known to have numerous benefits for human health. Various extraction methods have been used to obtain bioactive compounds. However, the conventional extraction method that is often used has several drawbacks including the use of large amounts of solvent and longer extraction time. Therefore, an alternative extraction method is needed to overcome the limitations of conventional methods. Extraction using supercritical carbon dioxide is an alternative extraction method that is more efficient with a shorter extraction time. This article aims to provide a comprehensive review regarding the extraction of bioactive compounds using supercritical carbon dioxide (SC-CO2). The use of low critical temperature and pressure during SC-CO2 extraction prevents the degradation of the bioactive components. In addition, because of its high selectivity, SC-CO2 extraction can produce a maximum yield with high purity of bioactive components. Therefore, extraction using supercritical carbon dioxide has the opportunity to be used as an alternative method to maximize the extraction process of bioactive compounds.

Abstract

Regional origin classification of Geographical Indication (GI) products is necessary for their authentication purpose. Among others, coffee is Indonesia's largest GI group, with Liberica being the least studied. This study aims to classify the geographical origin of dry- and honey-processed Liberica Tungkal Jambi ground coffee, which has been certified and dry-processed Liberica Probolinggo, which has the potential to be certified in the future. A total of 12 samples were tested using Near-Infrared Spectroscopy (NIRS). Spectrum data were analyzed using Principal Component Analysis (PCA) with various preprocessing spectral data, including Multiplicative Scatter Correction (MSC), Baseline, and Detrending. The results showed the ability of the combination of NIRS and PCA to classify three groups of coffee samples, namely: dry-processes Liberica Tungkal Jambi ground coffee, honey-processed Liberica Tungkal Jambi ground coffee, and dry-processed Liberica Probolinggo ground coffee, with the success rate ranged between 88 to 99%. Detrending was the most effective preprocessing for visualizing the classification. The result illustrates the great potential of near-infrared (NIR) spectroscopy in classifying the geographical origin of Liberica ground coffee.

Abstract

Currently, consumers are more interested in using herbs and spices in powder form because of their practicality. One of them is garlic powder, which has been circulating commercially. However, this commercial product has been found on the market in various quality classes, and it is suspected that there is potential for counterfeiting. Therefore, it is necessary to identify the quality of commercial garlic powder. The aim of this study is to determine the quality of commercial garlic powder based on its physicochemical properties and the level of consumer preference. In the primarily stage, commercial garlic powder sampling was carried out, namely bulk-quality samples from traditional markets and export-quality samples from modern markets. The selection of garlic powder products represents two consumer segments: heterogeneous consumers, represented by bulk-quality garlic powder, and homogeneous consumers, represented by export-quality garlic powder. Native garlic powder was prepared in the laboratory by slicing, drying (temperature 40-50C), and milling methods. Quality analysis has been carried out on physico-chemical properties, and sensory tests have been performed to determine the level of consumer preference. Commercial garlic powder has a different morphological structure compared to native garlic powder. Meanwhile, the color and allicin content of commercial bulk-quality garlic powder are significantly different compared to native garlic powder. Meanwhile, consumers tend to prefer commercial garlic powder in terms of color, aroma, and texture.

Abstract

Managing sugarcane harvesting and loading activities can increase the efficiency of sugar factory production. Scheduling this activity has a significant impact on reducing harvesting and loading costs, reducing the area of harvested land, and optimizing sugar production capacity. This study was conducted at a private sugar factory in Malang to develop a sugarcane harvesting and loading scheduling model. This model aims to optimize the sugar harvesting and transport scheduling so that the cost is lower and the sugar production capacity can be met. The model is built using LINGO 11.0 software. The results of the study showed significant improvements, namely the cost of harvesting and loading sugarcane decreased by 33.1% from Rp.  1.90 billion to Rp. 1.27 billion. Meanwhile, the harvested area decreased from 139.69 ha to 137.87 ha. In addition, sugarcane production increased by 24.6% from 11,140 tons to 13,887 tons per milling season, and the need for vehicles decreased by 39% from 2,870 to 1,736 units. The simulation results were then formed into a table containing a detailed schedule of harvesting and loading sugarcane as a recommendation to improve operational efficiency and factory profitability.
