Abstract

ABSTRACT  Shrimp shells are byproducts of shrimp processing which contributes about 30% of shrimp weight. These byproducts are notfully utilized and could negatively impact the environment. As an alternative to overcome these problems, shells could be used as a source of raw material for producing chitin, chitosan, and N-acetylglucosamine. N-acetylglucosamine is beneficialfor bone health, skin care, and improving memory. It has a potential to be applied to food products such as chocolate bars.An organoleptic test was done to a chocolate bar contained 0.7% of N-acetylglucosamine and the result showed that theproduct had a color score of 3.85% (Preferred), aroma of 3.92% (Preferred), texture 3.92% (Preferred), the taste 4:30%(Preferred). This shows that the chocolate bar with the addition of 0.7% of N- acetylglucosamine was liked and accepted bypanelists.It can be concluded that the N-acetylglucosamine chocolate product made in this research was accepted byconsumers.

Abstract

Pesticide is one of dangerous chemical compounds in environment. Its existence has spread so it can cause negative effect for human. Pesticide compound is toxic in for nervous system so that a quick detection system is needed to protect human’s health and as a control for agricultural product. Therefore, we conducted a research of electrochemical biosensors development  based  on  enzyme  acetylcholinesterase  in  electrode  to  analyze  pesticide residue  so  that  a  more  superior  and  reliable  biosensors  can  be  obtained  for  pesticide residue analysis in foodstuff samples, especially for agricultural product. Residue analysis of carbamate and organophosphate in foodstuff sample requires a sensitive, selective, cheap- and-easy-operated, and quick-analyzed tools. A new research has been designed in making of  biosensors electrode by  using immobilization method of  enzyme  acetylcholinesterase (AChE) with the supporting materials of Acetate Selulose (AS) and Glutaraldehid (GA) in biosensor electrode connected with electrochemical transducer. Designed biosensors were characterized, including Nernst factor, the detection limit, response time, and period of use. Next,  biosensors  were  tested  in  sample  of  vegetables and  fruits.  Expected  result  was  a biosensor prototype with better work than pesticide determination with instrument of Gas Chromatography (GC) and High Pressure Liquid Chromatography (HPLC). Biosensor development offers low cost, accurate, quick analysis time, and sensitive to detect pesticide residue. Keywords: : Pesticide, Biosensor, Electrochemical, Enzim, Sensitive

Abstract

Biomass has been suggested as a sustainable alternative to substitute fossil fuels. Based on the pyrolysis method, the biomass would be converted into energy through decomposition by thermal degradation under an inert atmosphere, resulting in charcoal, liquid, and gas products. The quality of oils is effectively enhanced through the pyrolysis of lignocellulosic biomass and plastic due to the facilitation of deoxygenation by plastics. This study investigates the impact of incorporating low-density polyethylene (LDPE) plastic in co-pyrolysis with sago dregs (SDs) waste. Pyrolysis of SDs and LDPE mixtures with ratios of 5:1, 4:2, 3:3, 2:4, and 1:5 at various temperatures of 375°C, 425°C, and 475°C. The maximum oil yield obtained for SDs and LDPE pyrolysis was 44.94%. The calorific value (CV) of all observed compositions is a minimum of 10,579.57 kcal kg-1 and a maximum of 11,545.21 kcal kg-1. The gas chromatography-mass spectroscopy (GC-MS) analysis confirmed the interaction between SDs and LDPE on co-pyrolysis. The addition of LDPE will produce rich aliphatic and aromatic compounds, like the proportions of alkanes (45.53%), alkenes (30.62%), alcohol (0.4%), and benzene (17.68%). Co-pyrolysis of SDs and LDPE promotes enhanced oil production by reducing oxygenated compounds and increasing hydrocarbon compounds.

Abstract

Desa Opaasi is one of the villages where many residents work as patchouli farmers. In 2022, the previous PKM team assisted the community by organizing equipment for distillation and purification of patchouli oil. The main focus of the current program is on the processing of patchouli harvests by farmers who still use conventional methods, such as using a machete to chop their patchouli harvests, making the process ineffective and inefficient. The PKMI 2023 Team then designed and created a patchouli chopping tool as a solution to enhance the efficiency and effectiveness of farmers in chopping their patchouli harvests. Additionally, PKMI team showed technical guidance on the proper use and maintenance of the patchouli chopping tool was provided to the patchouli farmers to ensure optimal utilization and care.

Abstract

Foodborne bacteria cause food spoilage, usually Staphylococcus aureus and Escherichia coli. Thus, synthetic preservatives are employed in food preservation to prevent food spoilage caused by microorganisms. Excessive use of synthetic preservatives can cause disease. Bio-oil has become a natural preservative because of its high phenolic content. However, bio-oil still requires purification because the initial bio-oil (grade 3) still contains carcinogenic compounds that are dangerous for consumption. Therefore, this study aims to determine the components of the bio-oil compound after purification and its effectiveness as an antibacterial. Durian shell (DS) is pyrolyzed in a heating reactor without oxygen at a temperature of 330–600ºC (flow rate 6ºC/minute) with a 2-3 cm material size. Furthermore, bio-oil purification includes stages of filtration using activated zeolite, fractional distillation at 70–200ºC (grade 2), and filtration using activated charcoal (grade 1). Bio-oil purification includes stages of filtration using active zeolite and activated charcoal (grade 2), and fractional distillation at a temperature of 150–200ºC (grade 1). Based on Gas Chromatography-Mass Spectrometry (GC-MS) analysis, grade 2 and grade 1 contain the major compounds 1,4-dimethyl-1h-imidazole and acetic acid. The research showed that bio-oil grades 1 and 2, when used at a 30% concentration, exhibit antibacterial strong effects against Staphylococcus aureus and Escherichia coli. These findings suggest that bio-oil grades 1 and 2 could be valuable natural preservatives.
