Abstract

Since 2006, Indonesia has led global production and export of palm-based edible oils. Government policies focused on advancing agriculture and agro-industries, particularly in downstream product development, provide opportunities to increase the economic value of these products, including palm oil products. Efforts to enhance downstream products include maximizing all palm oil potentials, including its waste. Global CPO production based on 2024 data is 79.6 million tons per year, with Indonesia contributing 59%. The potential waste is also very large, including the final waste which still contains around 20-25% oil and 3-5% phytonutrients. Proximate analysis and β-carotene content studies are used to evaluate the potential of CPO liquid waste for poultry feed. Proximate analysis results show low nutrient levels, including protein (<0.04%), carbohydrates (1.37%), total carbohydrates (<0.02%), total energy (5.20%), and crude fiber (<0.02%), making it unsuitable as a poultry feed substitute. However, based on β-carotene data, the waste can be used as an additive in poultry feed if stored for less than 28 days. The β-carotene degradation process follows zero-order reaction at heating and storage conditions (under room and dark storage).

Abstract

Kaempferia angustifolia originated in Southeast Asia and is widely used for its medicinal properties. One of which is from its flavonoids. The research aims to determine the optimal dosage of organic and inorganic fertilizers for promoting the growth and flavonoid production of K. angustifolia. The study was laid out in a split-plot design using organic fertilizers as the main plots (chicken and cow manure at 10 t.ha-1) and inorganic fertilizers as the subplots, consisting of 19 combinations of urea, SP36, and KCl. Each treatment has three replications.  The results showed that there is no interaction between organic and inorganic fertilizers in affecting the growth of Kaempferia angustifolia. Plants treated with chicken manure at 10 tons per hectare have a higher fresh weight than those treated with cow manure. Plants without inorganic fertilizer application showed suppressed growth and yielded more rhizomes three months after planting. Inorganic fertilizer promoted more shoots and tillers, with the highest value obtained from 100 kg.ha-1 urea + 200 kg.ha-1 SP36 + 200 kg.ha-1 KCl application.   The range of total flavonoids in inorganic fertilizer applications is 39.30-131.51% higher than the control, with the highest value observed at 200 kg.ha-1 SP36 + 200 kg.ha-1 KCl application. The results of this study would be useful for producing K. angustifolia for the medicinal industry, using either organic or inorganic fertilizers.

Abstract

A common enzyme for superoxide anion radicals biosensors is superoxide dismutase (SOD). Deinococcus radiodurans protein extract can replace the use of pure SOD enzymes for superoxide anion radicals biosensors. The purpose of this research is to determine the analytical performance of the superoxide anion radicals biosensor with protein extract of Deinococcus radiodurans immobilized on carboxymethylcellulose-gelatin-zeolit (CMC-G-Z) that is crosslinked by glutaraldehyde. The response surface method showed that the optimum condition for the biosensor was pH 7, protein extract concentration of 1075 µg/ml, zeolite concentration of 5 mg/ml, and glutaraldehyde concentration of 0.0042 M. Stability of the biosensor retained 67% of its sensitivity after use for 24 hours. The biosensor exhibits good analytical performance with a linear range from 0.1 – 0.8 mM, a detection limit of 77.84 µM, and a limit of quantification of 259.5 µM with a correlation coefficient of 0.9905.

Abstract

Arrowroot (Maranta arundinaceae L.) is a starch–producing plant that can potentially be used as an alternative substitute for wheat flour. Additionally, arrowroot can serve as a functional food, as it is not only a source of nutrition but also provides health benefits such as improving digestion and regulating blood sugar levels. Arrowroot tubers contain high levels of carbohydrates and bioactive phenolic compounds that function as antioxidants. Currently, no data is available on the nutritional content and antioxidant activity (DPPH assay) of arrowroot tubers from various regions of Java Island. This study aimed to analyze the quality and antioxidant activity of arrowroot tubers obtained from several locations in Java. The results of the proximate analysis (moisture and ash contents) showed that the lowest moisture content was in the Banjar 1 accession (3.44%), while the highest was in the Sragen 3 accession (12.47%). The Banjar 2 accession had the highest ash content (8.94%), while the Sragen1 accession had the lowest (3.98%). The antioxidant activity was indicated by the IC50 value, which is the concentration of the sample solution required to inhibit 50% of DPPH free radicals. Antioxidant activity analysis revealed that the Malang 1 accession had the lowest IC50 value of 163.16 ppm, indicating the highest antioxidant potential.

Abstract

Rhizome with high productivity and content of bioactive ingredients is the hope to be achieved from the cultivation of galanga (Kaempferia galanga L.). Galanga is used traditionally as a medicine for stomach ulcers, colds, headaches, coughs, diarrhea, facilitating menstruation, skin diseases, and rheumatism. Production of secondary metabolites is influenced by environmental factors and the place of growth. This study aims to determine the effect of the growing environment from two different locations on the essential oil content and its constituent components from the rhizome of the galanga accessions. The samples observed were nine accessions of galanga harvested at 6 months which were planted in the Bogor, namely Darmaga (L1) and Cisarua (L2) with a altitudes of 214 m asl and 780 m asl with different agro-climatic conditions. The accessions tested included Purbalingga (PBG), Cilacap (CLP), Purworejo (PWJ), Karanganyar (KRA), Pacitan (PCT), Madiun (MAD), Galesia 1 (GAL 1), Galesia 2 (GAL 2), and Galesia 3 (GAL 3). GAL 1, GAL 2, and GAL 3 are high yielding varieties of galanga that have been released by the Minister of Agriculture of the Republic of Indonesia and used as comparisons based on their essential oil content. Observations were made on the levels of essential oils and their constituent compounds using GC-MS (Gas Chomatography-Mass Spectroscopy). Differences in growing places affect the content of essential oils and their constituent components from the rhizome of the galanga accession. Environmental factors that influence are sunlight and water availability. The highest essential oil content (3.78%) was obtained from the MAD accession planted in Cisarua (L2) and the highest EPMS compound (34.74%) was obtained from the PCT accession planted in Darmaga (L1). There were 73 compounds detected with four main components, namely delta-3-carene, pentadecane, ethyl cinnamate, and ethyl p-methoxy cinnamate (EPMS).

Abstract

This research aims to develop a sensitive and selective nonenzymatic electrochemical sensor for glucose detection using a glassy carbon electrode modified with platinum nanoparticles (PtNPs) decorated on reduced graphene oxide (RGO). The structural properties and surface morphology of PtNPs/RGO composite were characterized using Raman spectroscopy and scanning electron microscopy (SEM). In addition, cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques were employed to investigate glucose measurements in human urine samples. The developed sensor shows an increasing anodic peak of glucose with a linear response at a concentration range from 10 to 1000 µM, with a detection limit of 5 µM. The proposed sensor also demonstrated good reproducibility, indicated by the value of relative standard deviation (%RSD) of 3.9%, and maintained its current response over seven consecutive measurements. Moreover, the proposed sensor exhibited high selectivity for glucose detection against several potential interferences, such as potassium (K+), chloride (Cl−), magnesium (Mg2+), ascorbic acid, dopamine, and urea, with recovery values of 96-102%, which are acceptable within the analytical range. Furthermore, this proposed sensor successfully detected glucose in human urine samples, and their concentrations were not significantly different when measured with a commercial glucose sensor.

Abstract

A simple, portable visible reflectance spectrophotometer was developed for classifying the quality of Curcuma xanthorrhiza Roxb. The device was assembled using consumer electronic components: an LED as the light source, a DVD optical layer as the diffraction grating, and a webcam as the detector, with web-based software (Spectral Workbench) as the signal processor. The spectrophotometer's performance was evaluated using standard Sudan III samples and powdered C. xanthorrhiza samples from two quality classes (A and B). Spectral data were analysed using principal component analysis (PCA) and partial least squares (PLS) regression.  PCA successfully grouped Sudan III samples by concentration and classified C. xanthorrhiza by curcuminoid content. A PLS regression model was developed for quantifying Sudan III, yielding R² values of 0.9909 for both calibration and cross-validation, with RMSEs of 0.3821% and 0.4152%, respectively. The results closely matched those from a commercial spectrophotometer. A PLS-discriminant analysis (PLS-DA) classification model for C. xanthorrhiza was also developed, achieving sensitivity and specificity values of 1. Additionally, semi-quantitative parameters such as decision limit (26.15% B), detection capability (41.06% B), and unreliability range (26.15–41.06% B) were calculated. The classification model showed strong sensitivity, specificity, and detection capabilities within acceptable limits. These findings suggest that this low-cost reflectance spectrophotometer, combined with chemometric methods, holds promise as a practical tool for the quality control of raw herbal materials.
