Abstract

The purpose of this study was to determine the effect of spraying the insecticide fipronil on the growth and intensity of pest attacks on green bean plants. This study used a randomized block design with four replications. The treatments tested in this study used application of the insecticide fipronil with a concentration of 2 ml/l in the vegetative and generative growth phases, the application of insecticides on vegetative growth only, the application of insecticides on generative growth only, and control without insecticide treatment.  The results showed that the insecticide fipronil used on vegetative and generative phases was used once and two times a week could reduce the intensity of leaf pests (24.98%) and pod pests (4.50%). Fipronil insecticide can also act in a plant growth substance as shown in the parameters of plant height, the number of leaves and components of mung bean seed yield is better than the control without fipronil application the application of insecticides on vegetative growth. The application of insecticides on the vegetative and generative growth phase by spraying insecticide once a week also affected yield components of 400.31g/clump and seed weight per mung bean plant of 27.67g/clump compared to other treatments.

Abstract

Low productivity of cayenne pepper (Capsicum frutescens L.) is often caused by high disease incidence. The application of biological agents like mycorrhizae and chitosan offers a promising strategy for sustainable intensification. This study aimed to evaluate the synergistic effects of mycorrhizae and chitosan on the growth, yield, and disease resistance of cayenne pepper var. Bara. A field experiment was conducted from April to July 2023 in Batu, Indonesia, using a factorial Randomized Complete Block Design (RCBD). The first factor was mycorrhizal dosage (M: 0, 5, and 10 g/plant ), and the second was chitosan concentration (C: 0, 4, 8, and 12 mL/L). Results showed a significant interaction (P 0.05) between mycorrhizae and chitosan on most vegetative and generative parameters. The treatment M2C3 (10 g/plant mycorrhizae + 12 mL/L chitosan) yielded the best performance, producing 8.03 t ha⁻¹, a 204% increase compared to the control (2.64 t ha⁻¹). This combination also significantly enhanced plant height, leaf count, and biomass. While no statistical interaction was found for disease incidence, both agents individually reduced disease severity. This study demonstrates a strong synergistic effect between soil-applied mycorrhizae and foliar-applied chitosan, highlighting its potential for significantly boosting cayenne pepper production.

Abstract

Kota Batu memiliki lebih dari 300 sumber mata air, namun debitnya menurun bahkan beberapa sumber mata air hilang setiap tahun akibat perubahan penggunaan lahan. Perubahan penggunaan lahan dari hutan ke pertanian menjadi salah satu penyebab utama menurunnya debit sumber mata air. Penurunan debit dan hilangnya sumber mata air menunjukkan pentingnya konservasi tanah dan air untuk menjaga keberlanjutan sumber mata air. Tingkat Pendidikan, pengetahuan dan sikap petani berperan penting dalam mendukung upaya konservasi. Penelitian ini bertujuan guna menganalisis hubungan antara tingkat pendidikan, pengetahuan dan sikap petani terhadap konservasi sumber mata air di Kota Batu. Penelitian ini memanfaatkan metode deskriptif kualitatif dengan data yang diperoleh melalui wawancara, observasi, dokumentasi, dan angket. Dilaksanakan pada Juli 2024 di Kota Batu, objek penelitian ini adalah petani di sekitar sumber mata air utama (Kasinan, Gemulo, Banyuning dan Terembulok). Jumlah data responden menggunakan rumus Slovin dengan toleransi kesalahan 10% yaitu sebanyak 120 responden. Analisis dilakukan dengan statistik deskriptif dan korelasi Rank Spearman menggunakan SPSS. Hasil menunjukkan bahwa sebagian besar petani berpendidikan rendah (SD), memiliki pengetahuan yang baik mengenai dampak perubahan penggunaan lahan terhadap hilang atau menurunnya sumber mata air dan kurangnya pengetahuan mengenai konservasi sumber mata air. Tingkat pendidikan memiliki hubungan yang kuat dalam menentukan sikap petani. Sebaliknya, pengetahuan tidak berhubungan dengan sikap petani.

Abstract

Coleoptera play a crucial role in maintaining the balance of agroecosystems through decomposition, nutrient cycling, and biological control. This study aimed to examine the effects of nitrogen (N) fertilizer and rice husk biochar on Coleoptera population abundance in a sorghum (Sorghum bicolor L.) plantation. Conducted at UNITRI Science Technopark, the experiment used a Randomized Complete Block Design with eight treatment combinations of N fertilizer (0, 100, 150, 200 kg/ha) and biochar (5 tons/ha), replicated three times. Coleoptera specimens were collected using pitfall traps and analyzed with ANOVA and DMRT. Results demonstrated that N fertilizer variation had no significant effect (p0.05) on Coleoptera abundance, while biochar application consistently and significantly increased individual counts (p0.05). From 1,533 identified individuals belonging to 11 morphospecies, the distribution was nearly balanced between natural enemies (777 individuals) and other insects. Biochar enhanced soil insect abundance by improving habitat quality, indicating its positive role in supporting Coleoptera populations and its potential as a key component of biodiversity conservation-based sustainable soil management.

Abstract. Widowati, Biru SM, Agastya IMI, Cahya UTW, Wilujeng R. 2025. Optimization of biochar and drip irrigation to improve chili yield and soil properties. Asian J Agric 9: 442-453. Cayenne pepper (Capsicum frutescens) is an important horticultural crop in Indonesia; however, its yield remains below optimal despite rising demand. This study intends to (i) assess changes in soil bulk density, particle density, and porosity; (ii) evaluate the effects of irrigation techniques and the application of biochar on chili yields; and (iii) identify the best combination for optimizing resource usage and yield. Eight different treatment combinations, each repeated four times, were used in a nested randomized design study conducted in Tunggulwulung Village, Malang. As the primary factor, the treatments included two main irrigation techniques (conventional and drip), which were further subdivided with different rates of biochar application (0%, 2%, 4%, and 6%). There were 160 pots total, with five plants per treatment acting as experimental units. Rice husks that had been pyrolyzed for three to four hours at 600°C were the source of the biochar. According to the results, adding biochar to conventional irrigation increases fruit weight by 125% and yield by about 130%. Drip irrigation with 4% biochar, on the other hand, is the most successful technique and yields much larger improvements, increasing fruit weight by 764% and fruit yield by 324%. Drip irrigation is more effective and yields better results than conventional irrigation, especially when combined with rice husk biochar. Furthermore, soil porosity and water use efficiency are significantly increased when 4% and 6% doses of biochar are added to drip irrigation systems.

Abstract

In mining areas, improper soil management frequently leads to soil degradation and the depletion or loss of N, P, and K nutrients. Bicomat is known as an effective amendment for improving physical properties in the short term, whereas its effects on chemical properties generally become evident only in the long term. The purpose of this study was to determine the effect of combining Bicomat and Tithonia compost on the chemical properties of Group-C post-mining soil after planting mustard greens. This study was conducted from October to December 2024 at the Science Technopark of Tribhuwana Tunggadewi University, Malang City, at an altitude of approximately 450 meters above sea level. The study employed a non-factorial Randomized Block Design (RBD) with 8 treatments and 3 replications. The tested treatments consisted of: KT1 (Non-Mining Soil Control), KT2 (Group-C Mining Soil Control), T1P1B1 (Soil 1, 200 g fertilizer, 10 t ha⁻¹ Bicomat), T1P1B2 (Soil 1, 200 g fertilizer, 20 t ha⁻¹ Bicomat), T1P2B2 (Soil 1, 300 g fertilizer, 20 t ha⁻¹ Bicomat), T2P1B1 (Soil 2, 200 g fertilizer, 10 t ha⁻¹ Bicomat), T2P1B2 (Soil 2, 200 g fertilizer, 20 t ha⁻¹ Bicomat), and T2P2B2 (Soil 2, 300 g fertilizer, 20 t ha⁻¹ Bicomat). The results showed that the combination of Bicomat and compost had a significant effect on improving the chemical properties of the Group-C post-mining soil. The best results for nitrogen, phosphorus, and potassium were obtained from treatment T1P2B2, while treatments T1P1B1 and T2P1B1 yielded the best results for organic C.
