Abstract

The aims of this study are to describe the learning process in animal structure courses and learning outcomes obtained by students of Biology Education Study Program, Teachers Training and Education Faculty, Siliwangi University Tasikmalaya after attending lectures. The research method used is survey data collection using a questionnaire. As many as 60 students who have attended and graduated in animal structure lectures in the 4th semester of the 2014/2015 academic year were used as research samples. Samples were taken using simple random sampling technique from a population of 90 students. Then the data obtained is processed using descriptive statistics. The results of the study show that students have an interest in animal structure courses, especially in practical activities. The implementation of learning in animal structure courses has not been carried out optimally. The indication is from the non-socialization of the learning model used by lecturers which has an impact on various generic skills that are not maximally trained and developed.

Abstract

Self-regulated learning is a constructive process that is active in setting learning goals. This ability should be possessed by every individual to become a successful learner. Another thing that students must have to be successful in the process and learning outcomes are learning motivation. This study aims to determine the correlation between learning motivation with self-regulated learning in grade X MIPA 9 SMA Negeri 1 Tasikmalaya City. This research was conducted in April 2019. The research method used was correlational with a population of all class X MIPA 9 students as many as 30 people. Samples were taken using a saturated sampling technique so that the entire population was sampled. The research instrument used in this study is the Motivated Strategies for Learning Questionnaire (MSLQ), which consists of 2 parts, namely motivational beliefs and self-regulated learning strategies. The data analysis technique used is the bivariate correlation regression test. Based on the results of the study, it can be concluded that there is a strong correlation (R = 0.761; R2 = 0.580) between learning motivation and self-regulated learning. The contribution of learning motivation to self-regulated learning is 58%.

Abstract

Improving the production of organic rice can be achieved by using certified superior seed varieties. The research aimed to test the adaptability of several superior rice varieties in organic farming systems to obtain varieties suitable for rice growth and yield in the Cipatujah District of Tasikmalaya Regency. A single-factor randomized complete block design was used in this study to test 3 superior varieties, namely Ciherang, Inpari 32, and Mekongga varieties. Each treatment was replicated 20 plots, resulting in a total of 60 experimental plots. The analysis results indicated that the soil at the demonstration plot location met land suitability and rice plant growth requirements with S1 (very suitable) criteria based on parameters such as pH, organic carbon content (C-organic), nutrient content of Nitrogen, Phosphor, and Potassium, bulk density, particle density, porosity, and soil texture. The superior variety treatments had a significant impact on plant height growth, although there were no significant differences observed in terms of tiller number, productive tiller number, grain yield per hill, filled grain per hill, grain weight per hill, and 1000-grain weight. The Ciherang variety showed the highest plant growth response and larger yield components compared to Mekongga and Inpari 32. The use of certified seeds in organic rice cultivation practices was proven to yield higher results compared to seeds from previous cultivation practices.

Abstract

Soil quality improvement can be achieved through the application of soil ameliorants such as Biochar. Developing superior varieties that are efficient in fertilization is also an effort to reduce the use of chemical fertilizers. This study aims to improve fertilization efficiency through the application of Biochar and the development of hybrid large red chili varieties at Siliwangi University. The research method used a Split-split plot design, consisting of large red chili varieties as the main plot, Biochar dosage treatment as the sub-plot, and different doses of inorganic fertilizers as the sub-sub plot. The main plot treatment consisted of four levels: Baja Variety (V1), UNSIL-01 (V2), UNSIL-02 (V3), and UNSIL-03 (V4). The sub-plot had two levels: without Biochar (B0) and 10 tons/ha of Biochar (B1). The inorganic fertilizer treatment consisted of three levels: 25% (P1), 50% (P2), and 75% (P3) of the standard dose. Each treatment was repeated three times, resulting in 72 research plots. The slow pyrolysis of coconut shell produced biochar with an average efficiency of 33.7% based on the dry weight of the feedstock. Optimal pyrolysis conditions, with temperatures ranging between 275°C and 485°C over 6 to 9 hours. Among the tested chili varieties, UNSIL-03 (V4) and Baja (V1) showed the highest growth performance, particularly in height and stem diameter, in biochar-amended soil. The application of 25% of the standard inorganic fertilizer dose, in combination with biochar, was sufficient to achieve optimal plant growth across most varieties, especially Baja (V1) and UNSIL-03 (V4).
