Abstract

This study aimed to evaluate the effects of planting media composition and the concentration of liquid organic fertilizer derived from cow urine on the growth and yield of pakchoy (Brassica rapa L.). The research was conducted from November to December 2025 at the TPH Tohudan Seed Garden, Klipan, Tohudan, Colomadu District, Karanganyar Regency, at an altitude of approximately 150 m above sea level, using a factorial Completely Randomized Design (CRD) with two factors. The first factor was planting media composition, consisting of soil; soil + rice husk charcoal (1:1); soil + compost (1:1); and soil + rice husk charcoal + compost (1:1:1). The second factor was the concentration of liquid organic fertilizer from cow urine, namely 0, 50, 100, and 150 mL L⁻¹ of water. The results showed that the planting media composed of soil + rice husk charcoal + compost (1:1:1) produced the best growth and yield of pakchoy, the optimal concentration of liquid organic fertilizer from cow urine was 100 mL L⁻¹ of water, and the combination of planting media and liquid organic fertilizer application had a significant effect on the growth and yield of pakchoy..

Abstract

Pest attacks are one of the main obstacles in the cultivation of long beans (Vigna unguiculata ssp. sesquipedalis) in Indonesia. This study aims to evaluate the effectiveness of cyanide acid content from various parts of the rubber cassava plant (Manihot glaziovii) in controlling Aphis craccivora pests and its impact on the growth and yield of long beans. The study was conducted in Sragen and the Laboratory of the Faculty of Agriculture, Tunas Pembangunan University, Surakarta during September–December 2024 with a completely randomized block design (RAKL) with two factors, namely plant parts (leaves, tuber skin, and tubers) and extract doses (0, 10, 20, and 30 ml/plant). The results showed that tuber skin fermentation (B2) was the most effective in reducing the percentage of pest attacks (30.80%) and attack intensity (40.44%). The treatment dose of 30 ml/plant (K4) gave the best results in suppressing pest attacks and increasing growth and yield parameters, such as plant length (141.64 cm), fresh stalk weight (1905.77 g), and fruit weight (497.22 g). The bioactive content in cassava tuber skin has the potential as a pest control agent as well as a plant growth stimulant. This study supports the use of environmentally friendly and sustainable local biopesticides to increase the productivity of long beans.

Abstract

Penelitian ini bertujuan untuk mengetahui respon beberapa varietas padi (Oryza sativa L.) pada berbagai frekuensi pemberian air terhadap karakter perakaran. Penelitian dilaksanakan di Demangan, Kecamatan Sambi, Kabupaten Boyolali pada bulan Juni sampai Agustus 2025. Percobaan disusun menggunakan Rancangan Acak Kelompok Lengkap (RAKL) secara faktorial dengan dua faktor perlakuan. Faktor pertama adalah varietas padi yang terdiri atas enam varietas, yaitu IR64, Mamberamo, Situbagendit, Way Apo Buru, Inpari 32, dan M-70D. Faktor kedua adalah frekuensi pemberian air yang terdiri atas empat taraf, yaitu penyiraman setiap hari, dua hari sekali, empat hari sekali, dan enam hari sekali. Parameter yang diamati meliputi panjang akar, diamaeter akar, luas permukaan akar, berat kering akar dan Roo/shoot ratio. Data hasil pengamatan dianalisis menggunakan analisis sidik ragam dan dilanjutkan dengan uji Duncan Multiple Range Test (DMRT) pada taraf 5%. Hasil penelitian menunjukkan bahwa varietas padi memberikan pengaruh signifikan terhadap panjang akar dan berat kering akar, Frekuensi penyiraman tidak memberikan pengaruh signifikan terhadap semua parameter yang diamati dan Interaksi antara varietas padi dan frekuensi pemberian air memberikan pengaruh signifikan terhadap semua parameter yang diamati meliputi panjang akar, diamaeter akar, luas permukaan akar, berat kering akar dan Roo/shoot ratio.
