Abstract

Lead (Pb) is a toxic heavy metal for humans. Agrochemical applications contribute to Pb contamination and accumulation in plants which is harmful to humans. This study aims to investigate the habits of horticultural farmers in applying inorganic fertilizers and pesticides intensively on Pb concentration in the soil and cultivated plants, and its effect on plant growth. The measured parameters consisted of soil and plant Pb content, soil pH, organic C, total N, available P, and exchangeable K. This study used a randomized block design consisting of 4 treatments (Control (KT); (PR); (TN); and (TP)). The results showed that horticultural farmers' dosage of inorganic fertilizers exceeded Indonesia Ministry of Agriculture recommendation. The application of inorganic fertilizers and pesticides by farmers (business as usual) increased Pb content in plants up to 31.46 mg/kg. Besides the application of inorganic fertilizers increases fertilizer residues in the soil by up to 65%, which increases environmental pollution even though the application of inorganic fertilizers increases plant growth and production (shoot length,  the number of leaves, and plant dry weight). Thus, wisely applying agrochemicals is required in order to support plant growth and production without further environmental problems.

Abstract

The purpose of this research is to develop a valid and reliable instrument for testing argumentation skills in buffer solutions in daily life. Argumentation skill test instruments are reviewed from theoretical validity (content and construct), empirical validity, and reliability. Development of argumentation skill test instruments using the ADDIE development model with stages: (1) analysis; (2) design; (3) development; (4) implementation; and (5) evaluation. This research was carried out until the initial implementation and then an evaluation was carried out. The argumentation skill test instrument that has been designed is then tested for theoretical validity through expert judgment involving three validators. The argumentation skill test instrument has criteria of theoretical validity if each statement has a mode ≥ 4 with valid categories. After being declared theoretically valid, argumentation skill test instruments are implemented to learners. The results of the argumentation skill test instrument are then analyzed to determine empirical validity and reliability. The results showed that the argumentation skill test instrument was declared theoretically valid where each statement had a mode of 5 with a very valid category. The test instrument is declared empirically valid where each question item has a consecutive calculated r value of 0.807; 0.879; 0.911; 0.911 is declared valid with r count > r table (0.468). The reliability of the argumentation skill test instrument of 0.876 is declared reliable with a r count > r table (0.468).

Abstract

This study aims to determine the effect of clove oil concentration and time of immersion in clove oil on the anesthesia, recovery time, and physiological responses in the payangka fish (Ophieleotris aporos). The experimental design was completely randomized with a 6 x 3 factorial arrangement. The first factor was a concentration of clove oil consisting of six levels i.e., 0.02; 0.03; 0.04; 0.05; 0.1, and 0.2 ml/L of water. The second factor was a time of immersion consisting of three levels i.e., 1; 3; and 6.5 hours. Results showed that the concentration of clove oil significantly (p<0.05) affected the anesthesia time and the recovery time after immersing. The length of immersing and concentration of clove oil also significantly (p<0.05) affected the concentration of glucose, but not significantly (p>0.05) affected the concentration of cholesterol. It showed that clove oil can be used as anesthetization for payangka fish in the appropriate dose. The optimal concentration of clove oil that can be used as anesthesia for the transportation of live payangka fish is 0.02 ml/L of water. Meanwhile, for handling activities on payangka fish, a clove oil concentration of 0.03 ml/L of water is recommended
