Abstract

This study aims to determine the effectiveness of a combination of inorganic fertilizers and the interval of biological fertilizer on the growth of superior crops (crassocephalum crepidiodes). This research was conducted in Pendem Village, Junrejo District, Batu City and integrated laboratory of Islamic University of Malang with the height of the area ± 641 meters above sea level, average temperature of 20º C. Rainfall 30 mm. This research was conducted in December 2018 until March 2019. This research uses factorial randomized block design (RBD) consisting of 2 factors. Factor 1 is the composition of inorganic fertilizer (P) consisting of 4 levels, namely P0 (without the provision of inorganic fertilizer), P1 (100 kg urea Ha-1), P2 (100 kg urea Ha-1 + 25 kg TSP Ha-1), P3 (100kg urea Ha-1 + 25 kg TSP Ha-1 + 25 kg KCl Ha-1). Factor 2 is the interval of biological fertilizer (K) consisting of 4 levels, namely, K0 (without the administration of Ultra-gen fertilizer), K1 (Provision of Ultra-gene fertilizer once every 5 days), K2 (Provision of Ultra-gene fertilizer once every 7 days) and K3 (Provision of Ultra gene fertilizer every 9 days) from 2 factors obtained 16 combinations, each treatment contained 3 samples and repeated 3 times so that there were 144 samples.The results of this study indicate that there is an interaction between inorganic fertilizers and biological fertilizer intervals. In general, inorganic fertilizer treatment yields tend to yield better results on the growth and yield of predominantly dominated plants in the P3 treatment (100kg urea Ha-1 + 25 kg TSP Ha-1 + 25 kg KCl Ha-1). Biological fertilizer treatment can provide interaction with plant height, leaf area.

Abstract

This study aims to determine the effect of NPK fertilizer dosage and when  trimming lateral shoots to growth and yield of curly chili plants. This research was conducted in Kukap, Poncosari, Srandakan, Bantul, Yogyakarta with a height of 20 masl, regusol soil type, pH between 5.3 - 6.8 and average temperature 260 C - 380 C , and is held from September to December 2018. This study was conducted using a 2 x 2 + 1 control factorial experiment compiled in a Complete Randomized Block Design (RAKL). The treatment consists of two factors, the first factor is the treatment of pruning. The second factor is the dose of NPK fertilizer. Each treatment was repeated three times. The results of the analysis showed that there were interactions between the two factors in the outcome variable, where the control treatment of pruning at 7 days and 14 days and the fertilizer dose of 1.25 tons/ha gave the highest fruit weight yield. Giving fertilizer doses and pruning times showed no significant effect on plant growth and quality

Abstract

This classroom action research aims to improve the mathematics learning outcomes of fifth-grade students at SDN Purworejo in the academic year 2024/2025, particularly on the topic of cube and cuboid volume, through the use of VOKUBASA media (Volume Kubus dan Balok Satuan). The study was conducted in two cycles, each consisting of planning, implementation, observation, and reflection stages. The research subjects were 15 students. Data collection techniques included tests, observation, interviews, and documentation. The findings showed a significant improvement in students' cognitive learning outcomes after the use of VOKUBASA media. In the pre-cycle stage, none of the students achieved the Minimum Completeness Criteria (KKM). However, by the end of the second cycle, the average score had increased, and most students exceeded the KKM. The use of VOKUBASA manipulable, visual mediamade abstract mathematical concepts more concrete and easier for students to understand. The media also increased student engagement and learning motivation. In conclusion, the application of VOKUBASA media in mathematics instruction effectively improves student learning outcomes in understanding volume concepts of cubes and cuboids.
