Abstract

In recent years, the exploration of natural supplements such as green tea extract and their potential benefits in livestock nutrition has gained considerable attention among researchers and agriculturalists. Green tea extract contains a high concentration of bioactive substances, such as polyphenols and catechins. This study aimed to explore the effects of varying doses of green tea extract on rumen fermentation parameters through an in vitro trial using sheep rumen liquids. A completely randomized experimental design was utilized to test the effect of 4 different doses of green tea extract treatments (0, 140, 280, and 560 mg/kg) on in vitro Hohenheim gas test method. The current study shows no significant effect of administering green tea extract at various doses on total gas production, total gas production per in vitro dry matter and organic matter degradability, volatile fatty acid per in vitro dry matter and organic matter degradability, methane production per inv vitro dry matter and organic matter degradability of green tea extract. Although no significant effects were observed on the investigated parameters, this study provides important insights in the understanding of the potential use of green tea extract in modulating fermentation processes in the ruminant’s stomach. In conclusion, the findings of this study underscore the impact of GTE on gas production regulation, highlighting its potential implications for gastrointestinal health

Abstract

The two most extensively beekeeping honeybee species were Apis mellifera and A. cerana. Other species that produced honey, albeit with infrequent cultivation, include A. dorsata, A. florea, and some stingless bees, including Trigona and Melipona. Different types of honeybees were known to affect the quality of honey. Hence, this investigation aimed to conduct a meta-analysis to examine the similarities in honey quality between honey sourced from beekeeping and wild honeybees. Data analysis was performed using the OpenMEE software, facilitating the calculation of effect size and standard error. The effect size and common error data were subsequently organized into separate columns within a CSV file. This CSV file was then imported into the JASP 0.16.2 software to conduct heterogeneity and Egger tests to detect potential publication bias. The findings indicated significant disparities in the quality of honey produced by beekeeping, wild, and stingless bee honey, as determined by various parameters, including pH value, moisture, total sugar, acidity, HMF (hydroxymethylfurfural), and diastase enzyme levels (p < 0.05). According to the results of the meta-analysis, honey from beekeeping exhibited superior quality to that of wild and stingless bees. However, the average values of all parameters still adhered to the established honey quality standards set by the Standar Nasional Indonesia and the International Honey Standard (IHS). Keywords: honey, honeybees, meta-analysis, physicochemical quality

Abstract

This study aims to (i) develop predictive models using statistical and fuzzy approaches, and (ii) evaluate their forecasting performance. The data were obtained from www.investing.com for the period 1961 to 2017 and focus on five ASEAN countries: Indonesia, Malaysia, the Philippines, Singapore, and Thailand. The statistical models used are Autoregressive Integrated Moving Average (ARIMA) and Exponential Smoothing, while the fuzzy approaches include Chen and Singh fuzzy time series models. The dataset was divided into training and test sets in a 75%-25% proportion. ARIMA models capture trends and autocorrelations in time series data, while Exponential Smoothing uses exponentially weighted averages. Fuzzy models are designed to handle uncertainty and linguistic patterns in data. The results show that Singh’s fuzzy model yields the lowest error for Indonesia, while exponential smoothing and Chen fuzzy time series model demonstrate the same lowest error for Malaysia. For the Philippines, exponential smoothing is most accurate, whereas ARIMA and Singh fuzzy time series achieve the smallest error for Singapore. For Thailand, exponential smoothing and ARIMA perform equally well. However, the robustness of the forecasting model cannot be determined from either statistical or fuzzy methods, highlighting the challenge in determining the most robust model for inflation in the ASEAN region. The 75%-25% data split may also limit the generalizability of the findings. This study contributes a rare cross-country comparison of statistical and fuzzy forecasting methods in the ASEAN context. It highlights the importance of model selection based on country-specific inflation behavior and provides insights for improving forecasting strategies in macroeconomic applications.

Abstract

Premium reserves play a vital role in ensuring that insurance firms can meet their future obligations to policyholders. Traditional fixed-rate approaches often fail to reflect market volatility, leading to potential misestimations. This study addresses this gap by integrating the Commissioners Method with the Vasicek stochastic interest rate model to evaluate premium reserves for whole life insurance. The research hypothesizes that the Vasicek model provides more realistic reserve estimates than fixed-rate models, that payment frequency and behavioral preferences significantly affect reserve levels, and that gender-specific mortality impacts reserve adequacy. Using BI-7D-RR interest rate data from 2019–2024, Vasicek parameters were calibrated and applied to reserve calculations. A sensitivity analysis was conducted by varying the model’s mean reversion, volatility, and long-term mean parameters. The results confirm that Vasicek-based reserves are more robust and realistic than fixed-rate estimates. Incorporating a DARA utility function adds behavioral realism, while payment frequency strongly influences reserve accumulation. Gender-specific mortality produces systematically higher reserves for male policyholders. Sensitivity analysis highlights the model’s robustness, with reserves responding predictably to parameter changes. This research contributes theoretically by linking stochastic modeling, demographics, and behavioral economics, while providing practical guidance for insurers to strengthen reserve adequacy and financial resilience under uncertainty.

Abstract

Saponins are secondary plant metabolites binding hydrophobic non-sugar components that can reduce ruminant methane (CH4) production. Previous studies revealed that tea saponin is one of the common sources of saponins used to reduce enteric CH4 production. However, the effect of different levels of dietary tea saponin on rumen fermentation remains inconclusive. This study aimed to investigate the effect of tea saponin on in vitro rumen fermentation and methane production through a meta-analysis approach. A total of 6 articles were selected and included in the meta-analysis database, continued by the statistical analysis using SAS software through mixed model formula. The results showed that tea saponin levels lowered in vitro organic matter degradability (IVOMD) and in vitro dried matter degradability (IVDMD; P=0.01) by a linear response. Furthermore, increased tea saponin levels in the diet reduced enteric CH4 emission expressed as CH4/DM substrate and CH4/IVOMD by a quadratic (P=0.01) and a linear response (P=0.04), respectively. Increased tea saponin levels also tended to decrease gas production linearly (P=0.08). Tea saponins inclusion also decreased pH levels linearly (P=0.04) but increased NH3 quadratically (P=0.01). Moreover, total VFA concentration in the rumen also raised quadratically, followed by the increased acetate (C2) and propionate (C3) proportion by a linear response (P<0.05). As a result, the C2/C3 ratio was decreased in a linear response (P=0.01) by the increased tea saponin levels, where the protozoa population was also diminished by a quadratic response (P=0.01). In conclusion, tea saponin levels directly reduced enteric CH4 production by diminishing microbial populations.

Abstract

Global warming, driven in part by livestock manure emissions, poses a major environmental challenge. Refuse Derived Fuel (RDF) offers a waste-to-energy solution by converting solid cow manure into an energy source. This study investigated the impact of Bacillus sp. inoculation on the biodrying process of cow dung. The main challenge in processing cow manure into RDF is ensuring that the moisture content and calorific value meet the minimum RDF standards. Therefore, a biodrying process was carried out on cow manure to achieve these required standards. Biodrying performance was assessed based on drying time, moisture content, pH, and calorific value. The results show that inoculation with Bacillus sp.. The results showed that inoculation with Bacillus sp. at 10⁶ log cfu ml⁻¹ kg⁻¹ yielded the most efficient outcome, achieving the fastest drying time (12 days), lowest moisture content (9.64%), optimal pH (7.8), and highest calorific value (2,656.5 kcal/kg). These findings confirm a direct link between moisture reduction and calorific improvement. Hence, bio-dried cow dung treated with inoculation of Bacillus sp. 106 log cfu ml-1 Kg-1 is recommended as a viable RDF material.
