Abstract

Bacterial leaf blight (BLB) is a significant disease of rice plants. It is caused by the Gram-negative bacterium Xanthomonas oryzae and often leads to yield losses. Excessive use of synthetic chemicals to control BLB has raised concerns over resistance and chemical residues. Therefore, natural alternatives are needed, such as Euphorbia hirta, which is traditionally used as a medicinal plant. This study aimed to determine the inhibitory power of E. hirta extracts against X. oryzae and to identify the presence of flavonoids, tannins, and saponins. Plant extracts were prepared by ethanol maceration, hot-water infusion (~90 °C), and fresh squeezing. Antibacterial activity was evaluated by the well diffusion method on Mueller-Hinton Agar with concentrations of 25–100% (v/v), using chloramphenicol as positive control. Inhibition zones were measured after 24–120 h. The results showed that all preparations inhibited X. oryzae, with ethanol extract producing the strongest activity (10.65–15.94 mm), followed by infusion (3.09–6.31 mm) and fresh-juice (1.50–4.85 mm), compared to chloramphenicol (21.40 mm). Phytochemical tests confirmed flavonoids, tannins, and saponins in all extracts. In conclusion, E. hirta demonstrates antibacterial potential against  , with ethanol extract being the most effective.

Abstract

This study aimed to evaluate the effect of edible bird’s nest (EBN) infusion (Aerodramus fuciphagus) on lowering low-density lipoprotein (LDL) levels in white rats (Rattus norvegicus) induced with hypercholesterolemia. Fifteen male Wistar rats were divided into five groups: negative control (distilled water), positive control (simvastatin 10 mg/kg BW), and three treatment groups receiving EBN infusion at doses of 10, 20, and 40 mg/200 g BW. LDL levels were measured before and after treatment using an enzymatic colorimetric method. The results showed that EBN infusion reduced LDL levels in all treatment groups, with the highest decrease at a dose of 40 mg/200 g BW (34.03%), followed by 20 mg (33.46%) and 10 mg (28.13%). Simvastatin, however, produced a greater LDL reduction (55.64%). In conclusion, EBN infusion can reduce LDL levels in hypercholesterolemic rats, particularly at doses of 20 mg/200 g BW, suggesting its potential as a natural lipid-lowering agent, although it is less effective than simvastatin.

Abstract

Many Automotive Engineering vocational school graduates end up working outside their field due to pressing economic needs. They tend to choose available jobs rather than wait for jobs that match their skills. Their families' limited financial situation means they don't have the flexibility to wait for job openings in the automotive industry, especially if those jobs require additional skills they haven't yet mastered. This situation reflects the fact that economic factors are the primary driver of career decisions, even when those decisions are not aligned with one's educational background. To address this issue, various strategies can be implemented. One such strategy is strengthening relationships between schools and industry through link and match programs. This study aims to determine the extent to which automotive engineering competence and the type of job pursued influence the job relevance of vocational high school (SMK) automotive graduates. A quantitative approach was employed using a survey method, and the data were analyzed through simple and multiple regression analysis. The sample consisted of SMK Automotive Engineering graduates in Gunungsitoli who had entered the workforce in 2023–2024. The results showed a significant relationship between automotive engineering competence and the type of job pursued with the job relevance of graduates. Both independent variables made a substantial contribution to the alignment between job and educational background.

Abstract

There is a gap between the objectives of secondary education programs and the current unemployment rate in Indonesia. Vocational High School (SMK) graduates, equipped with work knowledge and skills, still contribute significantly to the unemployment rate in Indonesia. Career guidance is essential, especially as initial preparation for entering the workforce for vocational high school students, as students still face challenges, such as deciding whether to work immediately or continue their studies at university after graduation. All these issues highlight the need for a more comprehensive approach to supporting students' career choices. This study aims to examine the effect of implementing the Theory of Planned Behavior (TPB) on career planning among students at SMK Swasta Pembda Nias. The three main components of TPB were analyzed in this study: attitude toward behavior, subjective norms, and perceived behavioral control. A quantitative approach using a correlational survey method was employed, with data analyzed through simple and multiple regression techniques. The population comprised all students of SMK Swasta Pembda Nias, with samples taken using random sampling techniques. The findings indicate that each variable (attitude, subjective norm, and perceived control of behavior) has a significant effect on students' career planning. Furthermore, these three variables simultaneously influence career planning significantly. These results suggest that the implementation of TPB is an effective approach to guide career counseling strategies, especially in rural vocational school settings such as Nias.

Abstract

The misalignment between Vocational High School (SMK) activities and the dynamics of industrial needs is a significant challenge in the vocational education system. This phenomenon not only has an impact on the increasing unemployment rate of vocational high school graduates but also has the potential to hamper innovation and competitiveness of the national industry due to the shortage of skilled workers who match market needs. One crucial problem that often arises in the context of vocational education in Indonesia is the disparity between the competencies produced by Vocational High School graduates and the specific demands required by the industrial world. This study aims to analyze the influence of internal and external factors on the success of the Teaching Factory (TEFA) program in improving student work skills at the Nias Regional Government Private Vocational High School. This study uses a quantitative approach with a correlation method. Data were collected through questionnaires given to students of the Light Vehicle Engineering Expertise Program who have participated in the TEFA program. Data analysis techniques used validity, reliability, and multiple regression tests. The results of the study indicate that internal factors, such as teacher competence, curriculum, facilities, and student involvement, as well as external factors such as industry partnerships, internship programs, and government support, significantly influence the success of TEFA. These findings underscore the importance of synergy between schools, industry, and government in providing vocational education that is responsive to the needs of the workforce.

Abstract

Teaching Factory in Vocational High Schools (SMK) is a forum to facilitate SMK students to have competencies, with the hope that SMK graduates can be ready for entrepreneurship and have competencies that are in accordance with industrial needs. This study aims to develop a SMK Teaching Factory management model that aims to improve entrepreneurship programs and industry-based student competencies in SMK by implementing the POAC (Planning, Organizing, Actuating, Controlling) management function. The type of research conducted is the Borg and Gall Research and Development model modified into five stages, using a qualitative approach. Data were collected through questionnaires and interviews with Teaching Factory managers and validated using technical and source triangulation. The data analysis technique was carried out using qualitative descriptive analysis of the Miles and Huberman model. This research produces a management model, model description, and guidance for using the Teaching Factory model for Vocational High Schools. The results of a limited initial field trial conducted by the Teaching Factory manager indicate that the Teaching Factory management model can be implemented in Vocational High Schools with a score of 89.33% in the good category. This finding explains that the application of the POAC management function in the Teaching Factory management model can facilitate Vocational High School students to improve entrepreneurship programs and industry-based competencies.
