Abstract

Shelf life is an important factor in determining the quality and safety of food for consumption. Refrigerator becomes an alternative in extending product shelf life. Shelf life is difficult to be identified if the product stored for too long. Smart label of Time Temperature Indicators (TTI) can record the product shelf life based on its storage time. In this research, identification of indicator and material for smart label development based on liquid diffusion in material was conducted. This study used several types of materials (Buffalo paper, HVS 80 gr, photo paper, concord, drawing paper and cardboard duplex), low viscosity indicators (board-marker ink, stamp, tubs, permanent tattoo and non-permanent tattoos) and high viscosity indicators (cooking oil, lubricant A and lubricant B). The initial phase was characterizations such as grammage, density, mass density and viscosity test aimed to determine the properties of indicators and materials. Identification was implemented by measuring the diffusion length of indicator in the material at 24, 48, 72 and 96 h in temperature of 30.15°C and 50°C for cooking oil, while 30.15°C and 5°C for oil A and B. The slope of diffusion length versus time is called by rate constant (k), where as the slope of ln k versus 1/T is called by activation energy (Ea). Best indicator and the material were selected based on their high value of Ea. Result showed that the ink was not be absorbed during storage due to its high volatility and low viscosity, while cooking oil, lubricant A and lubricant B have specific diffusion length during storage. These indicators and mediums were able to detect up to 4 days of shelf life during storage. Based on activation energy, the most suitable indicator for smart label was lubricant A. The best materials for this label development sequentially from low-to-high activation energy were Buffalo paper, duplex cartons, drawing paper, concord, HVS 80 g and photo paper.

Abstract

Research in fruit ripeness indicator is still experiencing especially due to major difficulties of several fruits with no color changes in its skin when it is ripen. From the previous research, there was found that ammonium molybdate [(NH4) 6Mo7O24.4H2O] embedded in the polymer matrix could be used as an indicator label to detect the ripeness of climacteric fruits base on the color change from yellow to blue and then green. However, the performance label still needs to be developed further. The surface of the label was still poor due to air or bubble trapping inside the film. It was found that mixing H2O2 and molydate agent produced air or bubble thus in this research, a pre-treatment of film solution was done to chase away the air by storing and vacuuming the solution in cold temperature and time period of storage. A variety of film drying method was also carried out to find the best temperature of the oven to produce smooth surface of the film. The sensitivity of the label to ethylene gas was improved by adding more agent solution into the film. The best form of smart labels was produced using an oven at 40°C for 18 hours. The label composition was 100 mL distilled water, 3.5 g PVOH, 2 mL glycerol, and a color indicator solution (ammonium molybdate and hydrogen peroxide ratio of 1:10) at 4 mL. The molydate solution had to be stored for 3 days in temperature of 7oC before used. The label sensitivity was improved as low as 100 ppm of pure ethylene gas. Label application in a pack of avocados showed a relationship between label color changes and fruit quality degradation. The value of hue label on days 0 to 6 changed from yellow to greenish yellow, while on the 7th to the 10th day the color of the label was still in the same color as the day of 6th. Decreasing the quality of fruit during storage can be seen from the increase in the percentage of weight loss and hardness of fruit texture.

Abstract

The effect of temperature treatment, either increasing or decreasing the temperature of leuco dyes, can produce thermochromic by looking at the changing color of samples resulting from experiments. The colors that are seen namely brightness (L), a* value, b* value, chroma, degree of hue (oHue), color difference ( E), and color density (CD). This research was conducted to analyze the temperature treatment of the thermochromic leuco dye against color characteristics resulting from meta-analysis using secondary data from pre-existing research. The total number of journals used was 21 studies and the data obtained were 82 sets of treatments. The data were then analyzed using IBM SPSS software, which used quadratic and linear regression models. The results of the study with a temperature range between -8°C to 95°C show that the effect of temperature treatment with an increase in temperature can cause a significant elevation impact on brightness values (p <0.002, R2 0.174), b* (P <0.01, R2 0.146), color difference ( E) (P <0.0012, R2 0.117), and ohue (P <0.053, R2 0.087). A significant reduction effect can be seen in the chroma value (P <0.007 R2 0.134) and the color density (P <0.007, R2 0.128). The impact of temperature treatment was not significant (p> 0.1) for a* value.

Abstract

Clean water and proper sanitation are fundamental human needs. Nganti Village, located in Ngraho Subdistrict, Bojonegoro Regency, faces significant drought and clean water shortages, particularly during the dry season. The water quality remains subpar despite the presence of springs and water reservoirs. Consequently, processing raw water from the village's reservoir can offer a viable solution. This service activity aims to harness water reservoirs as a clean water source through multimedia filter (MMF) technology. The activities, conducted from 2022 to the end of 2023, encompass four stages: socializing the program plans, constructing multimedia filters (MMF), installing the water treatment unit on-site, and evaluating water quality, followed by necessary follow-ups. The primary activities involve installing water treatment units with MMF technology in collaboration with village officials and the community. The treated water is then tested for quality at the IPB University laboratory. Test results indicate that MMF technology significantly improves water quality, reducing parameters such as Magnesium, Manganese, Calcium, Iron, and Phosphate by 25.8‒97.8%, thus meeting quality standards. However, some parameters, such as TSS, COD, and Zinc, still exceed quality standards, necessitating further processing. This advanced water treatment requires involvement from the local government, particularly in funding through community empowerment programs, to install advanced treatment units and provide operational support for these units.

Abstract

The onset of autistic disorder in children happens before 36 months and manifests in three main symptoms i.e. failure in social interaction, verbal and nonverbal communication, lack of interest and repeated behavior. There are three basic types in autistic disorder: Classic autism (Kanner syndrome), regression autism, and secondary autism. The cause of autism is mainly a neurobiologic factor with or without genetic predisposition. Environmental triggers such as subclinically virus infection and/or heavy metal intoxication such as Hg, Pb, Cd, As, Al could ignite autistic symptoms causing disfunction of metallothionein (MT). The function of MT is to modulate the arrangement of behavior, memory, emotion, and socialization. The psychiatric management of autistic children comprises medicamentous, behavioral, speech, occupational therapy and special education. Gangguan autisme pada anak timbul sebelum usia 36 bulan dan meliputi tiga gejala utama yakni kegagalan dalam interaksi sosial, komunikasi verbal dan nonverbal, serta terbatasnya minat dan tingkah laku yang berulang. Ada tiga tipe dasar gangguan autisme: Autisme klasik (sindroma Kanner), autisme regresif, dan autisme sekunder. Penyebab autisme terutama adalah faktor neurobiologis dengan atau tanpa predisposisi genetik. Pemicu lingkungan seperti infeksi virus subklinis dan/atau keracunan logam berat seperti Hg, Pb, Cd, As, Al dapat memicu timbulnya gejala autisme yang menyebabkan terjadinya disfungsi dari metallothionein (MT). Fungsi MT memodulasi pengaturan tingkah laku, memori, emosi dan sosialisasi. Penatalaksanaan psikiatrik pada anak dengan autisme meliputi terapi medikamentosa, perilaku, wicara, okupasi dan pendidikan khusus.
