Abstract

Tujuan penelitian ini adalah untuk mengetahui pengaruh penerapan model pembelajaran inkuiri terpimpin terhadap kemampuan berpikir kritis. Desain penelitian adalah group pretest-posttest non equivalen. Data penelitian diperoleh dari pretes dan postes pada setiap pertemuan, dihitung dengan rumus N- skor gain. Hasil penelitian ini menunjukkan bahwa Hasil penelitian ini menunjukkan bahwa penerapan model pembelajaran inkuiri terpimpin dengan skor gain 62, 23 lebih tinggi dibanding tanpa model inkuiri terpimpin 41, 03. Berati bahwa kemampuan berpikir kritis siswa pada kelas yang pembelajarannya menggunakan model pembelajaran inkuiri terpimpin lebih tinggi daripada kelas yang pembelajarannya menggunakan model diskusi kelompok. Kata kunci: model pembelajaran, inkuiri terpimpin, kemampuan berpikir kritis

Abstract

Hydroponic green fodder is a method for producing forage for livestock in a short time (approximately 7–8 days) without soil. It can be an alternative source of high–quality forage to increase the productivity of ruminant livestock. This research aims to compare differences in seed density and the addition of organic nutrients in the form of shallot skins to the productivity of maize green fodder. Fodder planting is done using a hydroponic system with an automatic watering system. The variables measured were fresh and dry biomass production, conversion of green fodder to seeds, plant height, and nutrient content in corn seeds and green fodder. The experimental design used was a 3 x 2 completely randomized factorial design with treatment factors in the form of seed density (1,25; 1,5; and 1,75 kg/m2) and organic nutrition (soaking with tap water and soaking with shallot skin). The results showed that the production of fresh biomass, dry biomass, and plant height were significantly different (P<0,05) influenced by seed density. Total fresh and dry biomass increased with increasing seed density (P<0,05). Plant height increases as seed density decreases (P<0,05). Soaking seeds using shallot skins did not have a significant effect on the productivity of corn green fodder. A seed density of 1,5 kg/m2 produces the best productivity in green fodder corn

Abstract

The aim of this research was to examine the germination test of corn seeds and sorghum seeds based on differences in harvest age (HST). This research was carried out in the Laboratorium basah of Technology and Livestock Management at the IPB Vocational School, Sukabumi Campus in November 2023. The method used in this research was seed germination using an opaque paper substrate with a rolled paper test set in plastic and then stored in a dark room or without light. This research used a 2 x 2 x 3 factorial Completely Randomized Design (RAL) with 2 factors, namely; The first factor is the seed factor which consists of two levels, namely corn seeds (J), and sorghum seeds (S), and the second factor is harvest age (HST) consisting of 2 levels, namely the 4th day (4), and the 4th day. 7 (7), 3 repetitions each. The two types of seeds and different harvest ages (HST), then the interaction between factors for each germination of corn seeds and sorghum seeds showed significantly different results or effects (P<0.05). The results of this study showed that the germination of corn and sorghum seeds harvested at different ages (HST) had different percentages of germination and root length. The best interaction was shown by corn seed treatment at 7 HST.
