Abstract: This study aims to analyze the impact of environmental turbulence on environmental sustainability and financial performance of Small and Medium Enterprises (SMEs) in Padang City, with environmental sustainability as a mediating variable. Environmental turbulence, including market changes, policies, and economic dynamics, is considered a significant challenge for SMEs to survive amidst uncertainties. The study applies Partial Least Square - Structural Equation Modelling (PLS-SEM) using data collected through questionnaires from SME owners and employees. The findings reveal that environmental turbulence does not have a direct significant impact on financial performance but positively affects environmental sustainability. Furthermore, environmental sustainability significantly contributes to improving SMEs’ financial performance. These results indicate that adopting sustainability practices, such as reducing resource usage and producing environmentally friendly products, can serve as a vital adaptive strategy to enhance efficiency, competitiveness, and profitability in the long term. This study recommends the importance of government and stakeholder support in helping SMEs integrate sustainability into their operations to create stability amidst business environment dynamics. Keywords: Environmental Turbulence; Environmental Sustainability; Financial                  Performance; Small and Medium Enterprises.

Abstract

This study aims to determine how long fermented sugarcane tops (Saccharum officinarum L.) and tithonia (Tithonia diversifolia) wafers can be stored. This study used a completely randomized design with four treatments and four replicates. The treatments consisted of T1 (15 days storage duration), T2 (30 days storage duration), T3 (45 days storage duration), and T4 (60 days storage duration). The variables measured were color, aroma, texture, density, water absorption, and total fungal colonies. The data obtained from the study were analyzed using the variance analysis method, and the differences in the means of each treatment were further tested using the Duncan Multiple Range Test. The results of the analysis showed that shelf life had a very significant effect (P<0.01) on color, aroma, texture, water absorption, and total fungal colonies but gave no significant effect (P>0.05) on wafer density. The average results of color (3.3 - 3.7), aroma (3.2 - 3.6), texture (3.1 - 3.6), density (0.60 - 0.71 g/cm3), water absorption (72.8 - 85.3%) and total fungal colonies (1.10 x 102 CFU/ml to 3.03 x 102 CFU/ml). The results of this study indicate that 60 days of storage on sugarcane tops and tithonia wafers can still maintain the physical quality of wafers in terms of color, aroma, texture, water absorption, and total fungal colonies.

Abstract

Limapuluh Kota Regency is one of the rice producing districts in West Sumatra Province, so an irrigation network is needed to meet water requirement for agricultural productivity. The problem that occurs in the Batang Sanipan 2 irrigation area is the inability of water to flow through the service area to the end point of the irrigation area. Based on observations from e-PAKSI data from the Limapuluh Kota Regency Public Works Office, water can only flow up to a distance of 3.175 km from the intake gate and experience water loss along 1.445 km to the end of the canal. Therefore, it is necessary to study the analysis of irrigation water requirement in the irrigation area of Batang Sanipan 2, Limapuluh Kota Regency. This type of research is descriptive with a quantitative approach. Research methods carried out directly in the field. Based on data analysis, the results obtained from the manual calculation of KP – 01 the maximum irrigation water requirement with a value of 0.139 m3/second which occurred in March, while in the Cropwat software the maximum irrigation water requirement with a value of 0.149 m3/second which occurred in July. The results of measuring the discharge at the intake of the Batang Sanipan 2 weir obtained a discharge of 0.378 m3/second. Based on this, water is sufficient to flow through the entire agricultural area of the Batang Sanipan 2 irrigation area, but the current conditions are that water is not able to flow through parts of the Batang Sanipan 2 irrigation service area.

Abstract

Pidan eggs can be made into less safe food because of the ingredients used in making them. Coconut fibre ash and quicklime are natural ingredients with alkaline pH values that can be used to make pidan eggs. This research aimed to compare the influence of ash coconut fibre and quicklime yang on egg quail's physicochemical and sensory characteristics. The study employed a methodological approach utilizing a fully randomized design comprising five treatments with four replications each. The treatments involved varying ratios of coconut fibre ash to quicklime: A (90:10), B (70:30), C (50:50), D (30:70), and E (10:90). Diversity analysis revealed that the duration of alkaline fermentation significantly affected (P<0.05) the moisture content, pH value, calcium content, sensory attributes of the albumen and yolk color, and texture. However, it did not significantly impact the aroma of pidan quail eggs. The best research results were a ratio of coconut fibre ash to quicklime of 10:90 with a pH value of 10.53, moisture content of 70.74%, calcium content of 0.51%, sensory value of albumen color of 3.80 (blackish brown), egg yolk color of 4.24 (dark green/dark), aroma of 3.04 (smells of ammonia), and texture of 3.84 (slightly dense).
