Abstract

This research aimed to build a model for estimating the shelf life of dried chilies in vacuum packaging stored at any storage temperature. The shelf-life estimation of dried red chilies was carried out based on the change rate of dried chilies quality parameters using the ASLT (Accelerated Shelf-Life Testing) method with the Arrhenius approach. The shelf-life estimation using the ASLT method was carried out by conditioning the storage room, which could accelerate the degradation reaction, stored at temperatures above room temperature. Prior to storage, red chilies were dried until their moisture content reaches 10%. Then it was packaged in vacuum packaging made of PE (polyethylene) plastic and stored at 35°C. During the storage period, the observation was conducted on some quality parameters, namely moisture content, color, and vitamin C content. The same experiments were also carried out at 40°C, 45°C, and 50°C to obtain different rate constant values. The shelf-life estimation results from the Arrhenius equation model were selected based on the critical parameter, in this study the critical parameter was the decrease of vitamin C content. The shelf life of dried red chilies that were packed in vacuum stored at room temperature (25°C) could maintain its quality up to 365 days. Keywords:  Arrhenius,  ASLT,  Red chili,  Vacuum packaging,  Shelf life,

Abstract

The global essential oil market is expanding rapidly, driven by demand from the pharmaceutical, cosmetic, and food industries. This has positioned Indonesia as a key producer and exporter of citronella essential. However, inconsistent processing methods lead to variable quality and suboptimal oil yields. This study addresses this gap by investigating how withering duration (0-72 hours) and distillation time (2-4 hours) affect yield and quality of distilled oil from Cymbopogon nardus (Mahapengiri variety). The results show that the highest oil yield (1.14%) was achieved with 72 hours of withering followed by 4 hours of distillation, demonstrating that prolonged withering significantly enhances extraction efficiency by reducing moisture content and facilitating oil release from plant cells. Quality assessments revealed that extended processing improved key physical parameters, including density (0.8897 g/cm³) and refractive index (1.4694), which conformed to Indonesian export standards (SNI 06-3953-1995). Chemical analysis using gas chromatography-mass spectrometry (GC-MS) indicated that optimal processing conditions increased the concentrations of citronellal (43.24%) and geraniol (21.73%), critical compounds that enhance the oil’s market value. However, longer distillation times also intensified the oil’s color, shifting it from clear to a deep yellow, which may influence consumer preference despite meeting industry chromatic standards. The study highlights the trade-offs between yield, quality, and visual characteristics in citronella oil production. These findings provide actionable insights for Indonesian producers aiming to optimize post-harvest techniques and improve the competitiveness of citronella oil in global markets.

Abstract

Competence plays an important role in determining the quality of an employee's work and their understanding of their field of work. A professional must have academic qualifications and abilities that are appropriate to their field of work in order to make an optimal contribution to the organization. Competence is also a measure of individual behavior related to excellent performance at work. In the face of increasingly fierce competition, organizations need quality human resources as a key factor for success. Human resources with high competencies will support the smooth implementation of tasks and the achievement of organizational goals. Conversely, if the quality of human resources is low, the overall performance of the organization will decline. This study aims to examine the influence of competencies and career development on employee performance in the Protocol and Communication Division of the South Lampung Regency. Involving 53 respondents and using quantitative analysis methods through the SPSS program, the results showed that competence had a positive effect on performance with a contribution of 69.3%, while career development had a positive effect of 74.9%. Simultaneously, both variables had a positive effect on employee performance of 80.7%, while the remaining 19.3% was influenced by other factors outside the scope of this study.

Abstract

This study aims to analyze two mainstream media outlets, detik.com and kompas.com, in framing the alleged exploitation and violence against former Oriental Circus Indonesia (OCI) performers. The analysis was conducted using the Pan and Kosicki framing method, which encompasses four structures: syntactic, rhetorical, thematic, and narrative. Furthermore, the 5W+1H approach was used to explore the basic elements of the reporting. The results show that the two media outlets present very different narrative constructions. Detik.com emphasizes the voices of victims with a human interest approach, framing the issue in the context of conflict between institutions and individuals, and calling for state intervention through human rights institutions. In contrast, kompas.com constructs a narrative of self-defense from the institutional perspective by emphasizing historical legitimacy, visual evidence, and a rhetorical approach focused on clarifying and restoring the reputation of OCI management. These differences in framing demonstrate how the media not only convey facts but also pay attention to public perception through the choice of language structure, narrative perspective, and specific communicative objectives. This research underscores the importance of critical awareness of media framing in issues involving moral conflicts, human rights and institutional interests.

Abstract

Understanding soil fertility, influenced by macronutrients like nitrogen, phosphorus, and potassium, is essential for adaptive agriculture implementation based on various soil conditions. Near-infrared spectroscopy technology provides non-destructive, rapid soil property measurements without chemicals, applicable both in-field and in-laboratory. However, the wide NIR spectrum range and neural network complexities can hinder Artificial Neural Network (ANN) training and inference, leading to time and resource inefficiency, especially without sophisticated computing devices. This study examines data reduction methods to enhance ANN performance in predicting soil macronutrients using NIR spectra. Multiple Linear Regression (MLR) and Principal Component Analysis (PCA) were applied to select wavelengths from the 1000–2500 nm for ANN input, comparing their performance. About 237 NIR reflectance data from paddy soil were transformed into absorbance data. MLR used forward selection to identify wavelengths with correlations higher than 0.9, while PCA selected wavelengths corresponding to the loading factor peaks for each principal component. These selected wavelengths served as inputs for the ANN model. The ANN’s performance was assessed using correlation and determination coefficients, RMSE, RPD, and model consistency. For nitrogen, the PCA+ANN model with reflectance spectra performed better (RPD 2.4-4.8) than the MLR+ANN model (RPD 2.2-2.6) using fewer wavelengths (5-9 for PCA+ANN vs. 9-12 for MLR+ANN). For phosphorus estimation, the PCA+ANN model also excelled (RPD 2.3-7.0 vs. 2.3-2.4) with fewer wavelengths (4-7 vs. 7). For potassium estimation, the PCA+ANN model showed superior performance (RPD 4.3-9.5 vs. 4.2-4.4), using the same number of wavelengths (4-8 vs. 4-6).
