Berbagai jenis kacang seperti kacang kedelai, kacang hijau, dan kacang merah 
sangat digemari dan banyak dimanfaatkan oleh masyarakat Indonesia. Permintaan pasar 
akan berbagai jenis kacang terus meningkat, namun belum dapat terpenuhi. Upaya yang 
dapat dilakukan yaitu menggunakan pembenah tanah berupa biochar untuk dapat 
meningkatkan hasil dan menjaga ekosistem lingkungan. Penelitian dilakukan untuk 
mengetahui pengaruh pemberian biochar terhadap karakter fisiologi serta hasil produksi 
tanaman kacang kedelai, kacang hijau, dan kacang merah. Penelitian dilaksanakan 
Desember 2023 sampai April 2024. Penelitian dilaksanakan di Desa Singasari 
Kawaranglewas, Laboratorium Kebun Percobaan, Laboratorium Agronomi dan 
Hortikultura, dan Laboratorium Agroekologi Fakultas Pertanian Universitas Jenderal 
Soedirman bulan Desember 2023 hingga April 2024. Penelitian menggunakan rancangan 
percobaan yang dirancang dengan Rancangan Acak Kelompok (RAK). Variabel yang 
diamati meliputi jumlah dan kerapatan stomata, luas daun, kehijauan daun, kandungan 
klorofil, bobot kering tajuk vegetatif, bobot akar vegetatif, bobot tajuk generatif, jumlah 
polong per tanaman, jumlah biji per tanaman, bobot biji per tanaman, bobot 100 biji, dan 
indeks panen. Hasil penelitian menunjukan bahwa pemberian biochar dengan dosis 10 
ton/ha meningkatkan bobot kering akar fase vegetatif akhir. Penggunaan jenis tanaman 
memiliki nilai berbeda nyata pada kerapatan stomata, luas daun, bobot kering tajuk 
vegetatif, bobot kering akar vegetatif, jumlah polong per tanaman, jumlah biji per 
tanaman, bobot biji per tanaman, bobot 100 biji, dan indeks panen. Terjadi interaksi antara 
jenis tanaman dan dosis biochar terhadap bobot kering akar fase akhir vegetatif, yaitu 
pada jenis tanaman kedelai dan dosis biochar 10ton/ha hasil tertingginya.

Various types of beans such as soybeans, green beans, and red beans are very 
popular and widely used by the Indonesian people. The high market demand for beans 
has not been met. Efforts that can be made are using soil conditioners in the form of 
biochar to increase yields and maintain the environmental ecosystem. The study was 
conducted to determine the effect of biochar on the physiological characteristics and 
production of soybeans, green beans, and red beans. The study was conducted from December 2023 to April 2024. The study was conducted in Singasari Kawaranglewas 
Village, Experimental Garden Laboratory, Agronomy and Horticulture Laboratory, and 
Agroecology Laboratory, Faculty of Agriculture, Jenderal Soedirman University from 
December 2023 to April 2024. The study used an experimental design designed with a 
Randomized Block Design (RAK). The variables observed included the number and 
density of stomata, leaf area, leaf greenness, chlorophyll content, vegetative crown dry 
weight, vegetative root weight, generative crown weight, number of pods per plant, 
number of seeds per plant, seed weight per plant, 100 seed weight, and harvest index. The 
results showed that the administration of biochar at a dose of 10 tons/ha increased the 
dry weight of the roots of the final vegetative phase. The use of plant types had 
significantly different values in stomata density, leaf area, vegetative crown dry weight, 
vegetative root dry weight, number of pods per plant, number of seeds per plant, seed 
weight per plant, 100 seed weight, and harvest index. There was an interaction between 
plant type and biochar dose on the dry weight of the roots of the final vegetative phase, 
namely in the type of soybean plant and the highest biochar dose of 10 tons/ha.
