Abstract

The poultry manure and vertisols matter have potency for reclaiming a soil. The research objectives was to study the effect of poultry manure (PM) and vertisols matter (VM) on availability and leaching of macro nutrient in coastal sandy soil treated by rainfall simulation. A laboratory experiment was conducted with lesymeters to measure nutrient leaching. The factorial 4 × 4 treatment applied was arranged by randomized completely block design with three replications. The first factor was level of PM consisted of 0, 20, 40, and 60 Mg ha-1. The second one wasthe level of VM consisted of 0, 5, 10, and 15%. Variables observed were soil physical and chemical properties such as bulk density (BD), particle density (PD), porosity, pF 2.54, pF 4.2, available water capacity (AWC), permeability, cation exchange capacity (CEC), available macro nutrients (N, P, K, Ca, Mg, and S) by Morgan Wolf extraction, and the rate of macro nutrient leaching measuared by Spectrophotometry and Atomic Absorption Spectrophotometry. Result of the research showed that application of PM and VM in the sandy soil decreased soil PD and BD, increased soil porosity and AWC, decreased soil permeability, and slightly increased soil CEC. Application of PM and VM increased soil available nutrient in the sandy soil. Up to 60 Mg ha-1 dose PM increased soil available nutrient, while 10 to 15% dose, VM did not increased it. The rank of nutrient leaching from high to low by rain simulation was N-NO3 -> SO4 = > K+ > Ca2+. Leaching of K and N-NH4+ could be reduced by soil amendment. Combination of PM 60 Mg ha-1 and VM 10% was the best soil amendment for increasing nutrient availability and decreasing nutrient leaching in the sandy soil.Keywords: available nutrient, coastal sandy soil, leaching, poultry manure, vertisols matter

Abstract

The entrepreneurial spirit within Chinese-Indonesian families has long been recognized as a factor in their economic resilience, yet the educational patterns that transmit this spirit across generations remain underexplored. This study aims to examine how family-based education fosters entrepreneurial character among Chinese youth in Surakarta, focusing on the interplay of cultural values, practical immersion, and adaptive strategies. The central research question asks: How do educational practices within Chinese-Indonesian families contribute to cultivating entrepreneurial spirit in the next generation? This research employs a qualitative approach using thematic analysis to interpret data gathered through in-depth interviews, observations, and documentation. The findings reveal three major themes: first, practical immersion as pedagogy, where children are engaged in family business tasks from an early age to internalize perseverance, discipline, and interpersonal competence; second, familial trust and solidarity as social capital, where kinship bonds and moral values of honesty, responsibility, and integrity sustain intergenerational continuity; and third, the negotiation of formal education, experiential learning, and technology, where families balance schooling with hands-on practice and cautiously integrate digital tools as both opportunities and risks. The study concludes that entrepreneurial education in Chinese-Indonesian families is not merely an economic strategy, but a cultural and ethical practice embedded in family life. Theoretically, this study shows that entrepreneurial spirit is socially enacted within kinship structures rather than taught solely in schools. Practically, the findings suggest that entrepreneurship programs can be strengthened through family-based approaches that emphasize early immersion, trust, ethics, and guided use of technology.

Abstract

The effect of observing entrepreneurial role models on critical thinking skills in entrepreneurship learning. Objectives: This research analyzes a PBL model by observing an entrepreneurial role model's effect on the critical thinking skills in entrepreneurship learning at Vocational High School. Methods: This study uses quasi-experimental research with a quantitative approach. The total population in this study was 463 students, and a sample of 60 students was obtained using a simple random sampling technique which was divided into two groups. This study uses an instrument essay questions tests in the form of pre-test and post-test. t-test analysis was conducted to test the hypothesis with a significance level of 5%. Findings: The results of the paired sample t-test obtained sig (2 tailed) 0.000 < 0.05. Thus rejecting H0 and accepting Ha. Conclusion: Observing an entrepreneurial role model significantly affects the critical thinking skills in entrepreneurship learning at Vocational High School. Keywords: entrepreneurial role model, critical thinking skills, entrepreneurship learning.DOI: http://dx.doi.org/10.23960/jpp.v12.i3.202220

Abstract

This study aims to (1) realize the design of the item color selector training kit and (2) determine the feasibility of the item color selector training kit. The research uses the ADDIE Models reference, namely: analysis, design, development, implementation, and evaluation. Data collection techniques used were observation and questionnaires. The testing consists of product validation by experts, testing by teachers, and testing by students. The data analysis technique used is quantitative descriptive. The results consist of: (1) item color selector training kit design consisting of training and jobsheets. The training sections include boxes, conveyors, selectors and microcontroller circuits, the jobsheet consists of three learning activities, namely (1) introduction of PLC and training, sorting and calibration, timers and counters. (2) the feasibility level of content validation is 89.39% (very feasible), from construct validation is 91.20% (very feasible) and from the trials students get results of 79.96% (feasible). Based on this percentage, the learning tools for the color selector training kit of goods are suitable for use in the learning process.
