Abstract

Cyprinidae is a group of freshwater fish families that has more than 2,420 species that are widespread throughout the world, especially in Central Kalimantan, Indonesia. Wide distribution and the presence of geographic barriers are thought to have an impact on morphological variations in species of the Cyprinidae family. In this study we will provide information on morphological characters on three species of the Cyprinidae family (Osteocillus vittatus, Barbonymus schwanenfeldii, Labiobarbus ocellatus) originating from Central Kalimantan. Data was taken from 3 locations originating from the Kahayan and Rungan river basins, Central Kalimantan. Morphometric measurements were carried out on 14 characters which included total length, head length, tail peduncle length, head length in front of the eyes, standard length, caudal fin length, tail peduncle height, dorsal fin height, body width, eye width and mouth opening width and meristrik in 5 characters which include the number of dorsal fin rays, cloacal fins, ventral fins, pectoral fins and caudal fins. Data analysis was carried out using the Principal Component Analysis (PCA) approach using PAST software. Based on the analysis results, it shows that the three species are morphometrically significantly separated based on the characters that have been measured. This is shown by the location of the species in each quadrant because they have significant differences in character. However, every individual in each species is in the same quadrant because they have similar characters.

Abstract

This study aims to analyze the effect of Inventory Management Practices, Inventory Efficiency (Inventory Leanness), and Supply Chain Information on the Business Performance of MSMEs in Indonesia. This study employs a quantitative approach using explanatory research design. Data were collected through an online questionnaire distributed to 73 MSME owners across different regions in Indonesia using purposive sampling. The research instrument was developed based on established indicators for each variable and measured using a Likert scale. Data analysis was conducted using SPSS, including validity and reliability tests, multiple linear regression analysis, coefficient of determination (R²), F-test, and t-test to examine both simultaneous and partial effects among variables. The results indicate that Inventory Management Practices, Inventory Efficiency, and Supply Chain Information simultaneously have a significant effect on MSME Business Performance. The coefficient of determination (R²) value of 0.612 suggests that 61.2% of the variation in business performance can be explained by the three independent variables. However, partial testing reveals that Inventory Management Practices do not have a statistically significant effect on Business Performance (p = 0.076), despite showing a positive relationship. In contrast, Inventory Efficiency (p = 0.009) and Supply Chain Information (p = 0.001) have a significant and positive effect on Business Performance. These findings suggest that the ability of MSMEs to maintain lean and efficient inventory levels, along with fast, clear, and transparent supply chain information flow, contributes more substantially to business performance improvement than inventory management practices when implemented independently.
