This study is expected to enrich literary studies and enhance readers’ appreciation of literary works.

This study aims to collect Serawai ethnic folktales, analyze their narrative structures, and identify the cultural values embedded within them. The research employs a qualitative descriptive method using structural and cultural value approaches. Data were obtained through interviews with informants, resulting in the collection of six Serawai folktales, namely Si Pahit Lidah (Serunting Sakti), Dusun Tinggi (Sebakas), Danau Kuranding, Batu Balai, Misteri Bukit Candi, and Sepit Kancing. The analysis focuses on structural elements, including theme, plot, characters and characterization, and setting, followed by an examination of cultural values using Clyde Kluckhohn’s cultural value orientation theory. The findings show that the six folktales are constructed through the integration of narrative elements that form a unified meaning and convey moral and cultural messages to the community. The dominant character, Serunting Sakti, represents wisdom, moral responsibility, and leadership. Furthermore, the analysis reveals that Serawai folktales contain five cultural value orientations proposed by Kluckhohn: the nature of human life, human work, human relations with time, human relations with nature, and human relations with others. These values are reflected in attitudes of wisdom, honesty, responsibility, hard work, appreciation of experience, environmental awareness, mutual cooperation, deliberation, and respect for customary traditions. Among these orientations, the most dominant is human relations with others. Overall, Serawai folktales function as oral literary heritage and as a medium for transmitting cultural values, preserving local wisdom, and strengthening Serawai cultural identity.

Attention mechanisms have been widely incorporated into recurrent neural network architectures for financial time series forecasting, with most prior work reporting improvements in price-level error metrics. This study revisits that claim through a controlled empirical comparison of four deep learning architectures on nearly two decades of Telkom Indonesia (TLKM) closing price data from the Indonesia Stock Exchange (IDX). The models evaluated are a three-layer Gated Recurrent Unit (GRU) baseline, a comparable Long Short-Term Memory (LSTM) network, a Bahdanau end-attention GRU (Attn-GRU-V2), and a multi-head self-attention GRU hybrid (Attn-GRU-V3). Each architecture is trained over 30 independent runs with distinct random seeds, and performance is reported as 95% confidence intervals derived from the t-distribution. Statistical comparisons employ the Wilcoxon signed-rank test, a nonparametric paired test appropriate given the confirmed non-normality of residuals. The main finding is a consistent trade-off: the plain GRU achieves the lowest RMSE (94.02 ± 1.22 IDR) across all 30 runs, while Attn-GRU-V2 achieves the highest directional accuracy (45.91 ± 0.09%), surpassing GRU in every independent run. Bahdanau attention weights are nearly uniform across the 30-day lookback window (coefficient of variation: 3.21%), indicating that the mechanism cannot identify selectively informative timesteps in this univariate price series. This finding is consistent with the weak-form Efficient Market Hypothesis for the Indonesian market. An ablation study reveals that a 20-day lookback window maximizes directional accuracy (47.72 ± 0.21%) for the Attn-GRU-V2 model. These results suggest that Bahdanau end-attention consistently and significantly improves directional accuracy relative to a plain GRU baseline, providing an architecturally attributable advantage for direction-based applications, even when absolute price-level error is not reduced. The directional accuracy values remaining below 50% across all models are consistent with a weak-form efficiency characterization of the Indonesian market.

This article examines Numbers 22:21–35 through narrative analysis and theological irony. The pericope of Balaam's talking donkey is one of the most unique narratives in the Hebrew Bible, combining supernatural elements with a profound theological critique of a mercenary prophet. This study aims to reveal how the author employs narrative irony as a vehicle for divine rebuke: God uses a mute animal to reprimand a prophet who should have been sensitive to His word. Using the narrative exegesis method that attends to plot, characterization, point of view, and dramatic tension, this article traces the theological meaning behind the irony. Findings indicate that this narrative is not merely miraculous but contains a critique of Balaam's ambiguous motivations between loyalty to God and temptation by material reward. The donkey, ordinarily silent, becomes an instrument of divine correction more obedient than the prophet himself. The theological implication is that God sovereignly uses any means to convey His will, including what is weak and despised by human standards.

This study aimed to identify the qualitative characteristics of local ducks in Kediri Regency, East Java, as a foundational basis for breeding and genetic improvement programs. A total of 250 female local ducks were observed across five subdistricts using purposive sampling. Data were collected through direct observation of feather color patterns and beak color and were analyzed descriptively. The results showed that all observed ducks had black beaks (100%) and brown head feathers (100%). Additional dominant characteristics included white feathers above the eyes (96%), brown wing feathers (98%), brown back feathers (100%), brown tail feathers (98%), and brown thigh feathers (100%). These findings indicate that Kediri local ducks are predominantly characterized by brown plumage with distinctive white stripes above the eyes and solid black beaks. The observed variations in feather and beak color are influenced by genetic factors, particularly melanin and lipochrome pigments. This study provides essential baseline data to support selective breeding strategies, genetic conservation, and the sustainable development of local duck resources, thereby contributing to regional livestock improvement programs.

Natural fiber based composite materials are increasingly being developed as an environmentally friendly alternative to synthetic fiber-based composites. This study aims to characterize the thermal and mechanical properties of natural fiber composite materials and evaluate their potential use as sustainable materials. Composites are made using natural fibers as reinforcement and a polymer matrix through a specific molding method. Mechanical property characterization includes tensile tests, flexural tests, and impact tests, while thermal property characterization is carried out using thermal analysis to determine the thermal stability of the material. The test results show that the addition of natural fibers has a significant effect on improving the mechanical properties of the composite, especially tensile strength and elastic modulus, compared to the unreinforced matrix. In addition, natural fiber composites show quite good thermal stability over a certain temperature range, making them suitable for non-structural applications. Based on these results, natural fiber composite materials have the potential to be developed as environmentally friendly materials that have competitive mechanical and thermal performance.

Fruit rot disease is one of the main obstacles in the cultivation of guava (Psidium guajava) because it directly reduces the quality and selling value of the harvest. This research aims to identify and characterize the fungus that causes fruit rot disease in guava. The research was carried out by observing disease symptoms in the field, isolating the pathogen from infected fruit, as well as macroscopic and microscopic characterization of the fungus using Potato Dextrose Agar (PDA) media. The results of the research show that the initial symptoms are blackish brown spots on the surface of the fruit which develop into sunken lesions and spread to cause the fruit to dry out. The fungal isolate has white colonies with a flower-like pattern and forms black aservuli. Microscopic observation shows that the conidia are fusiform, insulated, with darker pigmented middle cells and have a transparent appendix. Based on these morphological characters, the fungus that causes fruit rot disease in guava is thought to belong to the genus Pestalotiopsis sp. Further research is needed through molecular approaches, such as PCR or DNA sequencing, as well as pathogenicity tests to strengthen and confirm the role of this fungus as the main cause of fruit rot disease.

Mine disposal materials such as tailings, overburden, and waste rocks are critical components in mining operations that require comprehensive understanding of their geotechnical properties to ensure stability and safety of storage facilities. This literature review aims to analyze the role of particle gradation and mineralogical composition in determining shear strength and compressibility of mine disposal materials, with particular focus on nickel mining. A sistematic literature review method was employed by analyzing 30 scientific publications from 2019-2025 obtained from various academic databases. The review findings indicate that particle size distribution (gradation) has significant influence on shear strength and compressibility, where materials with coarser gradation and higher coefficient of uniformity (Cu) exhibit greater shear strength and lower compressibility. Mineralogy, particularly clay mineral content, increases cohesion and microporosity but also increases compressibility under loose conditions. Studies on nickel mine waste demonstrate that ferronickel slag possesses favorable drainage characteristics suitable for rockfill material, while tailings require strict gradation control. In conclusion, comprehensive characterization integrating gradation parameters (Cu, Cc, D50) with mineralogical analysis (XRD, XRF) is essential for predicting mechanical behavior of mine disposal materials and designing safe storage facilities.

This study aims to analyze the quality of coal from the AR_10 borehole in Muara Enim Regency, South Sumatra, based on proximate analysis. The AR_10 borehole has three coal seams (A, B, and C) that were analyzed using the standard ASTM method to determine the coal quality characteristics. The parameters analyzed include total moisture (TM), volatile matter (VM), fixed carbon (FC), ash content (Ash), calorific value (CV), and total sulfur (TS) on an as-received (AR) basis. The analysis results show that seam A has the highest moisture content (19%), seam B exhibits the optimal calorific value (6045 kcal/kg), and seam C has the highest fixed carbon content (42.63%) with the highest sulfur content (0.83%). The correlation between parameters indicates that increases in moisture and ash content negatively affect the calorific value, while an increase in fixed carbon is positively correlated with the calorific value. All three seams fall into the category of low to medium rank coal (subbituminous to high volatile bituminous) with adequate quality for power generation and industrial purposes. This research provides an important contribution to the characterization of Muara Enim Formation coal in South Sumatra for the optimization of local coal resource utilization.
