Abstract

Sustainable fertilizer practices are needed in the context of resource degradation, climate change and population growth. Farmers' decisions to adopt sustainable agricultural practices are influenced by economic, psycho-social and technological availability aspects. This research aims to explain the factors that influence farmers' decisions to adopt sustainable fertilizer practices. The research model uses the basic Technology Acceptance Model (TAM) and adds the socio-cultural dimension of farmers. The research was carried out by taking the case of shallot farmers' decisions regarding the use of fertilizer. The research was carried out using a survey approach of 111 shallot farmers taken using proportional sampling in the shallot production center of Brebes Regency, Central Java, Indonesia. Data were analyzed using Structural Equation Modeling-Partial Least Square (SEMPLS). The research results found that farmers' attitudes towards adopting sustainable fertilizer practices were influenced by factors such as perceived usefulness, perceived ease of use, and social influence, while farmers' intentions to adopt sustainable fertilizer practices were influenced by farmers' attitudes and habits. The conclusions of this study have implications for technological development and socio-cultural aspects to scale up sustainable fertilizer practices.

Abstract

Using quantitative descriptive methods in the form of critical thinking skills tests and concept mastery, this study intends to ascertain the profile of critical thinking skills and concept mastery of junior high school students on energy and its changes. The average score of students on the test was 36.60 out of 100. Students averaged 29.86 on the indication of providing a basic explanation, 29.79 on the indicator of drawing a conclusion, and 28.35 on the indicator of providing a more thorough explanation. Critical thinking abilities are among the things that all three lack. The concept mastery test scores for the cognitive domains of analyzing (C4) and evaluating (C5) were, on average, 35.72 and 34.62, respectively, placing the students in the intermediate range. The findings indicated that due to students' low literacy regarding energy and its changes, their inexperience with working on higher-level thinking questions, and their use of less varied learning methods, their critical thinking skills were in the poor category and their concept mastery was in the moderate category.

Abstract

DNA isolation is an important step for further molecular analysis. Coffee plants contain polysaccharides, polyphenols, and secondary metabolites which can contaminate the results of DNA isolation. This study was conducted to isolate DNA from arabica and robusta coffee leaves using a modified CTAB method and PCR optimization for amplification of matK and rbcL genes. DNA was isolated using buffers (CTAB 10%, PVP 1%, β-mercaptoethanol 1%, Tris-HCl 1M, NaCl 5M, and EDTA 0.5%), and eluted with TE-RNase. Genomic DNA of ten coffee plants was successfully isolated with concentrations ranging from 33-146 nm/µL with purity (A260/A280) 1.7-1.9. Based on the genomic DNA isolated, matK and rbcL  genes were amplified with initial denaturation conditions of 94°C (for 1 minute of matK and 4 minutes of rbcL) followed by 35 cycles of denaturation at 94°C for 30 seconds, annealing (adjusted to each primer), and extension at 72°C for 1 minute. The optimal PCR conditions were effective to amplify matK (900 bp) and rbcL (600 bp) genes. Thus, the modified DNA isolation method and PCR optimization can be used as an efficient tool for further molecular analysis of Coffea arabica L. and Coffea canephora Pierre ex A. Froehner.
