Abstract

Sycanus aurantiacus Ishikawa & Okajima, found in Bali, was first described in 2007 as a new harpactorine species based on morphological and biological characteristics; however, its genome has not yet been sequenced. In this study, we examine the mitochondrial cytochrome oxidase subunit I (MtCOI) nucleotide sequence of S. aurantiacus in order to determine whether it represents a new harpactorine species. A sample from Pancasari, Bali, Indonesia was collected at the same location S. aurantiacus was first discovered in 2007. The selected mtCOI gene (650 bp) was successfully amplified using mtCOI primer pairs LCO1490 and HCO2198, and the resulting MtCOI sequence of the S. aurantiacus sample was compared with those from other hapactorine species recorded in GenBank. This comparison revealed low genetic similarity between S. aurantiacus and most other harpactorine species worldwide, except for the Genus Sycanus (JQ888697) from USA whose mtCOI shares approximately 91% similarity with the Pancasari sample. Phylogenetic analysis indicated a close genetic relationship between Sycanus from Bali and the Genus Sycanus (JQ888697) from the USA. The mtCOI sequence of S. aurantiacus had not been recorded previously, and our comparison with existing Sycanus sequences provides support to the understanding that S. aurantiacus is indeed its own species.

Abstract

Recently, there has been a gap between the skills needed by industry and learning materials in schools that still need to meet expectations. Research internship programs (RIP) viewing as a link that can eliminate these disparities. However, there is no conclusive proof of the learning results of the program. This study seeks to dig deeper into information based on a stakeholder's point of view on the quality of skills demonstrated by students in research internship programs. This research is qualitative. The case study method approach analyzes phenomena in the workplace according to assessment reporting in terms of stakeholder perceptions. Research informants consist of primary, supporting, and critical stakeholders. This paper uses triangulation techniques to reduce data, present data, and draw conclusions. The results of this study indicate that students' readiness and skills affect hard-skill performance but do not significantly affect the results of the research conducted. Stakeholder perception states that schools need more time to be ready to implement research internships based on Ministerial Decree Number 123/M/KPT/2019.

Abstract

The Role of Parasitoids in Controlling Eucalyptus Gall Pests (Eucalyptus urophylla S.T. Blake) in Bali. Eucalyptus spp. is a plant native in Indonesia. Eucalyptus leaves are part of the plant that is harvested and used as industrial raw material. However, a gall attack on eucalyptus leaves resulted in the formation of galls, which resulted in decreased production in eucalyptus plants. Research on the role of parasitoids in controlling eucalyptus leaf weevil pests in Bali aims to determine the types of parasitoids that play a role in controlling eucalyptus leaf gall pests in Bali. This research consists of field research and laboratory research. Field research was carried out at eucalyptus planting centers in Bali. Laboratory research was carried out at the Integrated Pest and Plant Disease Management Laboratory, Agroecotechnology Study Program, Faculty of Agriculture, Udayana University. The research starts from April to October 2022. This research uses a survey method, sampling is carried out at eucalyptus planting locations in Bali. The results of the research found two types of insect pests that cause gall on eucalyptus plants in Bali, namely Ophelimus eucalypti and Ctenarytaina sp., and there are four species of parasitoids that play a role in controlling it. The four parasitoids are Closterocerus chamaelon Girault (Eulophidae), Megastigmus sp (Torymidae), Erytoma sp, Illger (Eurytomidae) and Quadrastichus mendeli Kim & La Salle (Eulophidae), with parasitization rate of 9.70%, 6.25%, 3.02%, and 2.05% respectively.

Abstract

Silba adipata is a new pest that attacks white chili pepper in Bali, Indonesia. Most farmers control this pest with synthetic insecticides although this method poses significant risks to human health and the environment. Therefore, innovations and control technologies that are environmentally friendly and sustainable are urgently needed. Preliminary results show that S. adipata frequently attacks local figs (Ficus variegata) in Bali. Dried figs (Ficus carica) have been reported to effectively attract S. adipata adults. This study aims to (1) determine the phytochemical compounds in F. variegata fruit extracts that have the potential to act as attractants for S. adipata during the process of searching for and locating host plants; (2) evaluate the effectiveness and efficiency of F. variegata fruit extract, nano fruit extract, and nanogel fruit extract as attractants for S. adipata on cayenne pepper plants. The methods used to achieve these objectives were (1) LC-MS/MS analysis for phytochemical profiling, and (2) a preference test to evaluate attractant efficacy. The results revealed that the phytochemical profile of F. variegata fruit extract includes 5-hydroxy-2-(4-hydroxyphenyl)-8,8-dimethylpirano[2,3-h]chromen-4-one, with the highest compound content (68.74%) in the fruit aged 9-16 weeks. The application of nanogel extract at a 50% concentration was highly effective and efficient as a biological attractant for S. adipata on white chilli plants in Bali. These findings strongly support the development of integrated pest management strategies in Indonesia.

Abstract

This study aims to offer alternative competency assessments based on Freedom Learning policies and education era 4.0 through the implementation of the 2013 revised curriculum. The minimum competency assessment refers to skills needed in the 21st century through student-oriented learning models, character values in the 2013 curriculum, and HOTS items with reference to literature studies. To improve students' literacy and numeracy skills in the minimum competency assessment, an appropriate approach to the competency assessment is needed, namely by implementing student-centered learning models. Some of these models have been widely discussed in a study. The results show that the role of students is greater in the learning, while the teacher acts as a supervisor. The implementation of the learning through the project learning approach also contains observation and analysis from students. So that competency assessment based on literacy and numeracy can be carried out comprehensively. Implementation of the National Examination which tends to use learning material from student textbooks will only cause students, teachers and student guardians to be burdened with time, energy, and mind. The competency assessment instrument as a substitute for the national assesment requires progressive learning, not necessarily memorization but observation and analysis. Thus, students are required to deal directly with the object of learning material.
