Abstract

The research was aimed to determine the physical and chemical characteristics of mangos in various packing methods during storage. Factorial Completely Randomized Design with four treatments and three replications were used in this research. The treatments were individually and collectively packed mangos which were stored at 10 and 200C. The physical and chemical changes of mangos in the flexible packaging (individual and collective) were slower than mangos without packaging. Collectively packed mango stored was with the storage temperature of 100C was found to have longer shelf life than that of other treatments. On day 25, the collectively packed mango had weight loss of 1,464%, 0,316 Kgf hardness, 11,4% total sugars, 0,44% total acids, and 229,44 mg/100g vitamin C. Further duo-trio test indicated that panelists could detect the differences of the taste between packed and freshly harvested mangos. The hedonic test shows that most panelists preferred the taste of mangos that were collectively packed and stored at 100C (on day 10). Key words: Mangos, method, packaging, storage

Abstract

Nursanty N, Saputra D, Santoso B, Sugiarty Y. 2020. The effect of addition of STPP (Sodium Tripolyphospate) on decreasing oxalic acid levels in taro starch. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Taro has the potential to be developed into an alternative food source due to its high nutritional content but the presence of a toxic ingredient in the form of oxalate in the tubers which can cause itching on the skin, mouth and throat. Oxalates come in two forms, namely oxalic acid and calcium oxalate. This study aims to determine the effect of STPP (Sodium Tripolyphospate) Cross-Linking on reducing levels of oxalic acid in modified taro starch. The design used in this study was a factorial randomized design with one factor. The treatment consisted of 4 levels and each treatment was repeated three times. Treatment consisted of the STPP concentration (B0 = 0%, B1 = 0.5%, B2 = 1%, B3 = 1.5%). The parameters observed were oxalic acid levels. The results of the analysis showed that the difference in the starch concentration of STPP had a significant impact on decreasing the level of oxalic acid in taro starch. The levels of oxalic acid were 11.35% at 0% STTP treatment, 7.98% at 0.5% STTP treatment and 5.04% at 1% STTP treatment and 1.5%. From the data obtained, it can be seen that the more STTP concentrations are added, the lower the oxalic acid levels in taro starch.

Abstract

Organophosphate pesticides are one of the causes of contamination in animal feed. The cholinesterase enzyme test is used to diagnose toxic exposure due to organophosphate pesticides. Quantitative research with survey design using cross sectional design using 35 samples of cows. The study was conducted in March - September 2020. Concentration measurement on cholinesterase enzyme concentrations of blood plasma used the biosystem A15 DGKC-Colorimetric Kinetic method. This study aims to evaluate the concentration of the enzyme cholinesterase as a marker of organophosphate poisoning in cattle. Blood samples were collected from the ventrolateral neck veins of male and female cattle aged 1-7 years and collected from local cattle in the Ogan Ilir area. The results showed that the cows raised in breeders were exposed to organophosphate pesticides as indicated by a decrease in the concentration and levels of the cholinesterase enzyme in the plasma of female cows. Cholinestrase enzyme levels in female cows were 0.20 ± 0.067 U / ml and bulls were 0.27 ± 0.183 U / ml. The highest concentration of cholinesterase enzyme levels occurred in cows aged 2 years, namely 0.25 ± 0.34 U / ml and the lowest was in cows aged 7 years, namely 0.12 ± 0.04 U / ml.

Abstract

Pancasila is the basis of the Indonesian state with values ​​originating from Indonesian culture and culture, viewing life as an Indonesian way of life and reflecting respect for human dignity and human rights. As an open ideology, Pancasila has the freedom to follow current developments and introduce it to the behavior of Indonesian society. In the case of correctional institutions, the ideal goal is disciplinary and reform initiatives that are primarily based on the values ​​of Pancasila. Prisoner development is a system that includes various elements such as philosophy, legal basis, goals and system approach. Communication is key to fulfilling the prison officer's mission, especially when it comes to effective safety management. The revitalization of correctional administration is aimed at improving the implementation of correctional tasks, objectivity in assessing changes in inmates' behavior, the role of community leaders, security of correctional institutions, and protection of ownership of evidence. However, challenges remain, including a lack of police training, unsafe working conditions, and inadequate facilities. Therefore, this research aims to identify the causes of conflict between prisoners, assess the implementation of security controls, analyze obstacles in their implementation and find solutions to overcome these obstacles.

Abstract

Cadmium (Cd) is a toxic heavy metal with the potential to contaminate the environment, particularly in landfill sites using open dumping systems, such as the Sukawinatan Landfill in Palembang. This study aims to measure Cd levels in scavengers’ hair as an indicator of heavy metal exposure. A cross-sectional study design was conducted in January 2024, with hair samples collected from five respondents using purposive sampling techniques. Cd levels were measured using the Atomic Absorption Spectrophotometry (AAS) method. The results showed that Cd levels in the scavengers' hair ranged from 0.31 to 0.99 ppm, exceeding the normal limit set which is <0.10 ppm. The duration of work as a scavenger was identified as the dominant factor influencing Cd levels, although anomalies were observed in younger scavengers with high exposure intensity. These findings suggest that the working environment at the landfill significantly contributes to the accumulation of Cd in the body. This study provides preliminary insights into the health risks faced by scavengers at the Sukawinatan Landfill, which can serve as a basis for developing policies and mitigation measures to improve scavengers' occupational health and safety.
