Indayani I, Pulungan AS, Prasatya D, Miranda M, Mardiyah NU, Ramadhani CS, Umayah A, Gunawan B, Arsi A. 2022. Inventory and identification of mites on roses in Ogan Ilir District, South Sumatra Province. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 751-758. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Roses are widely cultivated by the public because of their beautiful and beautiful appearance as well as their fragrant and distinctive aroma, so they are nicknamed the queen of flowers, but on the other hand, roses are easily attacked by various species of mites. This study aimed to determine the species of mites on roses so that this research can make it easier to recognize and overcome the symptoms of mite attacks on roses. This research was conducted in the villages of Timbangan, Palem Raya, Sembabu Island, and Tanjung Sejaro, North Indralaya District, Ogan Ilir Regency, South Sumatra Province using survey and sampling methods. The results of the study have obtained 2 species of mites with the genus Tetranychus spp. The spread of mites occurs rapidly due to wind and human activities. Mites are polyphagous, so the possibility of expanding the host due to this pest should be watched out for. Mites attack can cause the process of formation of leaves and stems to be hampered so that the productivity of ornamental plants decreases. The mites damage the plant by sucking the liquid from the leaf cells which results in pale spots due to the damaged epidermal cells due to being sucked in. Although the individual damage caused by mites is small, with a population of thousands of mites attacking plants, it will cause more injuries so that it can reduce the photosynthetic ability of plants. So, roses are plants that are liked by many people but are often attacked by mites. It is better if the rose has been attacked by mites to minimize the spread of the attack, it is expected to spray pesticide liquid, rely on natural enemies, and plant high-yielding varieties.

Abstract

The imbalance between labor supply and demand often leads to unemployment in a given region. The unemployment rate serves as a key indicator to assess the overall health of the economy. Utilizing Artificial Neural Networks (ANN) as a predictive tool has emerged as a reliable solution to forecast unemployment rates in Batam City, using 7 input parameters. The methodology employed in this predictive model is the Backpropagation algorithm. This involves dividing the dataset into two distinct components: training data, consisting of 4 parts, and the remaining data set aside for testing purposes. This division results in a substantial allocation of 95% for training data and a significant 79% for testing data. The accuracy achieved by this model forms the basis to evaluate its potential success in forecasting unemployment rates for the upcoming year. By harnessing the capabilities of Artificial Neural Networks and employing the Backpropagation methodology, it is possible to predict unemployment rates in Batam City. The outcomes of this analytical approach can serve as a reference to address labor imbalance issues, while also providing a pragmatic tool to enhance economic planning and policy formulation for a more sustainable future.

Abstract

This research aims to determine the motivation used to increase employee productivity at LPP RRI Medan and the efforts made by organizations or companies to motivate their employees. The research results show that LPP RRI Medan provides motivation to its employees in two ways, namely materially and non-materially, but when implemented, it is inconsistent in providing work motivation to its employees. This incident resulted in many employees who were not motivated to do their jobs well. Efforts taken include not being too harsh in criticizing and correcting employees, for example, when an employee makes a mistake, the head of the company should reprimand them properly and direct the employee to make improvements. Then often carry out controls during working hours so that employees feel cared for and they feel motivated by the presence of the head of the company or organization. This study uses a qualitative method. Research is carried out directly in the field or object where all data is collected by observation and interviews.

Abstract

In the era of globalization and digitalization, challenges to national identity are increasingly complex due to shifting values and cultural influences. This study aims to explore the strategic role of schools in strengthening character education through school culture, integration of local wisdom, and the implementation of the Merdeka Curriculum. Using a descriptive qualitative approach and thematic analysis techniques, the study reveals that schools serve as key agents of cultural transformation and guardians of national values. The findings indicate that character development can be effectively achieved through synergy between formal education, local cultural practices, school leadership, teacher role modeling, and collaboration among schools, families, and communities. A consistent school culture, context-based learning rooted in Pancasila values, and extracurricular activities highlighting local culture have been proven to foster students’ tolerance, responsibility, and patriotism. These findings emphasize the importance of holistic and contextual approaches in developing student character grounded in the Indonesian national identity.
