Abstract

Maize (Zea mays L.) is the main food crop in Indonesia after rice, but is vulnerable to attack by plant pests (OPT), including Spodoptera frugiperda, an invasive insect that attacks corn plants. This research aims to observe the population, level of attack and characteristics of the pest of S. frugiperda in West Lombok Regency. Based on observations, the eggs of this pest are brownish white, round in shape, and have an average size of 0.33 mm × 0.47 mm. The male pupa is reddish brown with dimensions of 14.25 mm × 4.32 mm, while the female pupa is larger, namely 17.53 mm × 5.13 mm. Larvae are found in various instars (2-6) with sizes from 1.53 mm to 35.16 mm, and colors varying from light green to dark brown. Male imagos are smaller than females, with a length of 12.45 mm and a wingspan of 27.73 mm, while female imagos have a size of 14.38 mm and a wingspan of 31.47 mm. The highest population was found at location 3 with 123 larvae, while the lowest population was at location 13 with 1 larva. The highest attack rate occurred at location 7 (50%) and the lowest at location 11 (5%). The observation method includes assessing the level of damage based on the attack intensity score (0–4). This research proposes further studies to understand the distribution and control mechanisms of S. frugiperda in order to minimize its impact on corn cultivation, especially in Nusa Tenggara Barat, Indonesia.

Abstract

This study aims to determine the effect of applying various concentrations of botanical pesticides derived from Virginia tobacco stem waste on the diversity of spiders in potato plants. The research was conducted in Sembalun Bumbung Village, Sembalun District, East Lombok Regency, West Nusa Tenggara Province. The method employed was an experimental method with field trials, using a Randomized Block Design (RBD) with six treatments: P0 (control), P1 (abamectin), P2 (Virginia tobacco stem extract 2 ml/L), P3 (Virginia tobacco stem extract 4 ml/L), P4 (Virginia tobacco stem extract 6 ml/L), and P5 (Virginia tobacco stem extract 8 ml/L). The experiment was conducted in three blocks, resulting in 18 experimental units. The results showed that the application of various concentrations of botanical pesticides from Virginia tobacco stem waste did not significantly affect spider diversity in potato plants. However, the P3 treatment (Virginia tobacco stem extract 4 ml/L) exhibited a higher tendency in population, diversity index, abundance index, and dominance index compared to other treatments.

Abstract

The bekeeping of stingless bees is gaining popularity and developing in West Nusa Tenggara, as it provides an alternative livelihood and plays a vital role in the ecosystem through pollination. Despite growing public interest, detailed data on the diversity of stingless bee species and the challenges farmers face, particularly pest and disease infestations, remain scarce in some areas, such as Central Lombok. The aim of this study was to identify the bred species of stingless bees and the pest and disease species found in bee colonies in Rarung Village. The research was conducted from Juni to September 2024. The research methodology included field surveys, interviews with 4 farmers using snowball sampling techniques. In each farmers, we collected stingless bee and their pests from 10 stup and preserved in alcohol 70%. Morphological identification of bee species and pests was done in Plant Protection Laboratory, University of Mataram . The results showed that four species of stingless bees were being bred in Rarung Village: Tetragonula laeviceps, Tetragonula biroi, Tetragonula clypearis, and Tetragonula sapiens. Other major identified pests included ants (Formicidae), geckos (Gekkonidae), wasps (Vespidae), and signs of fungal pathogens. The results of this study show that bee species from outside Lombok were found in Rarung village that indicate thespecies diversity was affected by the practice of introducing species from outside Lombok.

Abstract

This study examines the influence of legal compliance on the financial performance of Micro, Small, and Medium Enterprises (MSMEs) in Indonesia, with a particular focus on financial stability, profitability, and competitiveness. Employing a descriptive-analytical design with a conceptual approach, this research synthesizes legal and financial theories through an extensive review of secondary data, including academic literature, regulatory frameworks, and governance studies. Legal compliance is operationalized across four key dimensions: business licensing, taxation, employment, and consumer protection. The findings indicate that legal compliance plays a strategic role in enhancing financial stability by reducing regulatory risks, minimizing unexpected costs, and improving cash flow management. Furthermore, compliance contributes to profitability through cost efficiency and improved access to financing with more competitive capital costs. In terms of competitiveness, legally compliant MSMEs demonstrate stronger reputational capital, greater market access, and higher adaptability within digital and global markets. The study also highlights that compliance should not be perceived merely as a regulatory obligation but as a financial strategy that strengthens governance quality and long-term business sustainability. However, the effectiveness of compliance is contingent upon regulatory simplification and MSME capacity, including legal literacy and administrative readiness. This study contributes to the integration of business law and financial performance perspectives in the MSME context and offers policy-relevant insights for strengthening MSME resilience.

Abstract

Good performance management of state civil servants requires reliable human capital, which has knowledge, expertise, abilities, and skills for carrying out its main tasks and functions. However, problems with its implementation still involve complaints from the public regarding the performance of the state civil apparatus, especially in Bantan District, Bengkalis Regency. The aim of this research is to analyze the influence of human capital on the performance of state civil servants. The research method is quantitative and descriptive, with a sample of 37 state civil servants and data processing using linear regression. Research findings show that knowledge partially has a negative effect on the performance of state civil servants, and expertise, abilities, and skills partially have a positive effect on the performance of state civil servants. Simultaneously, knowledge, expertise, abilities, and skills have a positive influence on the performance of the state civil apparatus. The implication of these findings is that the leadership of Bantan District, Bengkalis Regency, needs to improve the performance of state civil servants in public services and teamwork in achieving work effectiveness and efficiency.

Abstract

Sweet potato (Ipomoea batatas L.) is an important food commodity in Indonesia and is widely used as an alternative carbohydrate source. This study aims to determine the effect of several types of mulch on the intensity of wireworm attacks and sweet potato (Ipomoea batatas L.) yield. The research method used was an experimental field trial. The experiment was designed with RAK (Randomized Block Design), with three treatments. The treatments were without mulch (K0), black silver plastic mulch (K1), and straw mulch (K2). The results of the study found two species of wireworm pests, namely Phyllophaga sp. and Leucopholis sp. The highest attack intensity was obtained in the K2 treatment at 33.42%, followed by K1 at 28.08%, and the lowest in K0 at 23.10%, but not statistically significantly different. The highest tuber yield was obtained in the K0 treatment at 2,129 g per treatment. Regression analysis showed a negative relationship between attack intensity and tuber yield with an R² value of 0.6801.
