Abstract

Insect diversity in agricultural ecosystems is influenced by cropping patterns and physical environmental conditions. In cabbage cultivation, it is crucial to understand cropping management to support the sustainability of agricultural ecosystems. This study aims to examine the effects of cropping patterns and environmental factors on insect diversity and evaluate the effectiveness of sticky traps in cabbage fields. Monoculture and polyculture systems (a combination of cabbage and lettuce) were tested to assess differences in insect community structure based on diversity, abundance, evenness, similarity, and dominance. The study was conducted from July to August 2019 using sticky traps in yellow, green, and white colors. The analysis included the Shannon-Wiener diversity index (H'), evenness (e), dominance (D), species richness, and Sorensen and t-Hutcheson tests. Environmental factors such as temperature and humidity were also analyzed to assess their impact on insect community structure. The results showed no significant differences in insect community structure between monoculture and polyculture systems, with the Aleyrodidae family dominating both systems. Temperature and humidity significantly influenced the insect community. Yellow sticky traps were found to be the most effective in capturing insects compared to green and white traps.

Abstract

The problem of waste transportation is a major challenge in waste management in Salatiga City. With the amount of daily waste generated reaching 457.81 m³ and the volume transported only around 327.33 m³, the level of waste transportation has only reached 71.72%. This study aims to evaluate and optimize the current waste transportation route through a spatial approach using QGIS software. The methods used include field observation, primary and secondary data collection, and spatial analysis of the distribution of routes and workloads of the transport fleet consisting of 9 arm roll units and 1 dump truck unit, with a total average daily trip of 58 trips. The results of the comparison between the existing route and the planned route show a daily route length efficiency of 10.57 km (1.15%), fuel consumption savings of 2.73 liters per day, and travel time efficiency of 25 minutes. The volume of transported waste also increased from 83,730 kg/day to 89,500 kg/day (up 6.89%), which was achieved through more optimal route planning, additional trips to TPS Boja and Tingkir, and equalizing the workload between drivers. The results of this study confirm that GIS-based route optimization can increase the efficiency of distance, fuel, time, and productivity of the waste transportation system as a whole in Salatiga City.

Abstract

Using appropriate bedding can enhance the welfare of beef cattle. This study was designed to evaluate the daily behavior of beef cattle kept on different types of bedding. Field research was conducted over a period of two months, using eight beef cattle, which were divided into two groups based on the type of bedding used, namely straw and rubber mats. The daily behaviors observed were the duration and frequency of eating, aggressive behavior, lying down, sleeping, standing, and elimination. The observation used was an intermittent method. The first group consisted of a pen block with straw bedding, and the second group consisted of a pen block with carpet bedding. Data analysis used the t-test and analysis of variance at a significance level of 5%. The results showed that all parameters did not reveal any differences; however, sleeping behavior was higher (P < 0.05) in the straw-bedded pens, with the highest percentage of sleep occurring in the afternoon. This study concluded that both straw and rubber carpet bedding are still capable of supporting the normal expression of the main daily behaviors of cows. Both types of bedding are still suitable for use in beef cattle husbandry systems.
