Provision of Fermented Coffee Skins as Additional Feed For The Growth of Goats

2023-09-13T06:52:17+07:00

Coffee skin is one of the wastes generated from coffee bean processing which is still potentially used as animal feed through the fermentation process, especially for goats as ruminants. Coffee skin fermentation using local micro-organisms (LMO) produces the best quality, and the provision of 10% substitution has a significant effect on the growth of pigs. The purpose of this study was to be able to determine the response to the appearance of prospective parent goats given fermented coffee husk waste as additional feed to their growth before the reproductive phase. The method used in achieving these objectives is the experimental design method using a Completely Randomized Design (CRD) with 4 treatments, namely: without additional coffee husk (Ko), giving coffee skin 5% (K1), 10% (K2), and 15% (K3) and each treatment was repeated 3 times. The basic feed given is in the form of forage mixed with grass and legumes, and coffee skin is given before being given forage. The results showed that giving fermented coffee skins additional feed had a significant effect (P<0.05) on body weight gain. The higher the level of fermented coffee peels the higher the average added weight until the level of 15% (K3) showed the best results with an additional body weight of 211g/day, but not significantly different (P> 0.05) with K1, and K2. From this study, it can be concluded that the provision of fermented coffee skin waste as additional feed has a significant effect on the additional body weight of goats up to a level of 15%.

The Rapid Detection of Pork Gelatin in Hard Shell Capsule on Supplement Products Using FTIR and PCA

2023-09-13T06:51:58+07:00

This study aimed to develop a fast and low-cost detection method to determine the difference between hard shell capsule on supplement products containing pork or non-pork gelatin by using Fourier Transform Infrared (FTIR) spectroscopy and Partial Component Analysis (PCA). Twelve samples of hardshell capsules were used, among which Eight samples were pure made from pork and some of them adulterated with cow. The samples were detected before using real-time PCR to determine the identity of the samples. All the gelatin samples were measured with the FTIR spectrophotometer in the reﬂection mode. Spectra were collected in the wavenumber range from 4000-650 cm^-1. The results show that the PCA model with the data were pre-processed before PCA was performed. The absorbance data from FTIR were pre-processed using Savitsky-Golay smoothing technique and continued with normalization by peak normalize before subjected to PCA. This newly developed method is fast, involves simple sample preparation and is low cost.

Low-Cost Solar Energy Harvesting: A Study on Dye-Sensitized Solar Cells Using Inthanin Leaf Extract as a Natural Photosensitizer

2023-10-01T07:40:10+07:00

The world is actively pursuing renewable energy resources to combat environmental pollution and greenhouse gas emissions caused by the burning of fossil fuels. Solar energy is the most abundant, continuously available form of renewable energy, and dye-sensitized solar cells (DSSCs) are being explored as an alternative to traditional silicon-based solar cells due to their low cost of materials, ease of production, and efficiency. The photoanode is a crucial component in DSSCs, and the main challenges faced by these solar cells are charge recombination and low light harvesting ability. This study aims to investigate the efficacy of natural dyes as the sensitizer for the fabrication of DSSCs. Natural pigments were extracted from Inthanin leaves using the solvent extraction technique. The concentration and composition of the pigment were analyzed through pigment analysis utilizing UV a spectrophotometer. Inthanin has a higher chlorophyll a to b ratio. A higher chlorophyll a to b ratio has been shown to be associated with improved light harvesting and electron transport efficiency. This is because chlorophyll a is more efficient at transferring electrons to the electron transport chain than chlorophyll b. The higher chlorophyll a to b ratio could lead to improved electron transfer to the photoanode. The photoelectric parameters of the DSSC were evaluated using I-V characterization. DSSCs coated with Inthanin dye extract produced a short circuit current density (J_sc) of 0.02 mA/cm², open circuit voltage (V_oc) of 0.07 V, fill factor (FF) of 33% and an efficiency (????) of 0.1%.
