Abstract

Agriculture in Indonesia has various types of crop commodities that can be cultivated and developed for food, clothing, and medicinal needs. One such crop is pagoda mustard (Brassica narinosa L.). This study aims to determine the effect of the interaction and optimal dosages of coconut shell charcoal and nitrogen fertilizer on the growth and yield of pagoda mustard in yellow-red podzolic soil. The research was conducted in the Greenhouse of the Faculty of Agriculture, Tanjungpura University, Pontianak, from July, 2024, to September, 2024. This study employed a factorial completely randomized design (CRD) with two factors. The first factor being coconut shell charcoal (K) with two levels, and the second factor being nitrogen fertilizer (N) with three levels, each replicated four times. The first treatment factor consisted of coconut shell charcoal at two levels: 40 g/polybag and 80 g/polybag. The second treatment factor involved nitrogen application at three levels: 2.25 g/plant, 2.8 g/plant, and 3.3 g/plant. In total, there were six treatment combinations, each replicated four times, resulting in 24 experimental units. Each experimental unit contained five sample plants, leading to a total of 120 plants. The observed variables included leaf count, root volume, dry weight of the plants, and fresh weight of the plants. The results indicated an interaction between the application of coconut shell charcoal and nitrogen fertilizer on the dry weight and root volume variables. The use of 80 g/plant coconut shell charcoal combined with 3.30 g/plant nitrogen fertilizer produced the best growth and yield for pagoda mustard in yellow-red podsolic soil.

Abstract

Pengaplikasian amelioran dan pupuk NPK pada tanah ultisol dapat meningkatkan kualitas tanah secara fisik dan kimia. Penelitian ini bertujuan untuk mengkaji peran amelioran dan pemupukan NPK dalam meningkatkan produktivitas jagung hibrida pada tanah ultisol. Penelitian dilakukan dengan menggunakan rancangan acak kelompok faktorial. Perlakuan amelioran sebagai faktor pertama dengan 4 taraf yaitu a0, tanpa amelioran; a1, biochar sekam padi 5 ton ha-1; a2, lumpur sawit 5 ton ha-1; a3, gabungan biochar sekam padi dan lumpur sawit 10 ton ha-1. Pemupukan NPK sebagai faktor kedua yang terdiri dari 5 taraf yaitu p0, tanpa pupuk NPK; p1, 150 kg ha-1; p2, 200 kg ha-1; p3, 250 kg ha-1; p4, 300 kg ha-1. Hasil penelitian diperoleh bahwa interaksi perlakuan amelioran dan pemupukan NPK dapat meningkatkan variabel tinggi tanaman, diameter tongkol serta panjang tongkol. Perlakukan pemupukan dapat meningkatkan volume akar, berat pipilan basah, dan berat kering pipil. Perlakuan amelioran dapat meningkatkan variabel volume akar. Perlakuan NPK 150 kg ha-1 serta gabungan biochar sekam padi 5 ton ha-1 dan lumpur sawit 5 ton ha-1 merupakan dosis terbaik yang dapat meningkatkan produktivitas tanaman jagung pada tanah ultisol. Kata kunci: amelioran, kesuburan tanah, produksi jagung, tanah ultisol

Abstract

Durian peel is one of the agricultural wastes that has the potential to become a valuable product if processed properly. It contains secondary metabolites such as phenols, alkaloids, tannins, and saponins. These compounds can be utilized as active ingredients in the formulation of botanical insecticides. However, there have been no reports on the use of durian rind as a base material for botanical insecticide production, thus necessitating a study to determine the effect of durian rind extract on test insects, particularly the fall armyworm (Spodoptera frugiperda). This study also aims to investigate the effects of various concentrations of durian rind extract on the mortality of S. frugiperda. The research was conducted from September 2023 to December 2024 at the Pesticide Laboratory of Universitas Tanjungpura. The study employed a leaf-dipping method using corn leaves and consisted of a preliminary test, advanced test, and antifeedant assay. The antifeedant test was carried out using both choice and no-choice methods with the following concentrations: 0% (control), 0.1% (LC10), 0.4% (LC25), 1.4% (LC50), and 4.6% (LC75). The observed variables included mortality percentage, sex ratio, average pupal weight, average larval weight, number and viability of eggs, and feeding activity of S. frugiperda. The extract at a concentration of 4.6% had a significant effect on the duration of the imago and pupal stages, total eggs per female, and the male sex ratio of S. frugiperda. Durian rind extract requires high concentrations to affect the growth and development of S. frugiperda, thus it is classified as a botanical insecticide with low toxicity.

Abstract

Growth and Yield Response of White Radish (Raphanus sativus L.) to the Application of Rabbit Urine and KCl Fertilizer in PMK Soil. Radish (Raphanus sativus L.) is a root vegetable of the Brassicaceae family, closely related to cabbage. Based on data from the Central Statistics Agency of West Kalimantan (2021), the productivity of radish in West Kalimantan in 2020 decreased compared to the previous year. Increasing radish production can be achieved through agricultural intensification using Podsolik Merah Kuning (PMK) soil (Ultisol). The main problem of PMK soil is its low fertility. One way to improve the chemical properties of PMK soil is to apply organic fertilizer, namely rabbit urine liquid fertilizer, and inorganic fertilizer, namely KCl. This study aimed to determine the best concentration of rabbit urine and the most effective dose of KCl fertilizer for the growth and yield of white radish in PMK soil. The research was conducted in the experimental field of the Faculty of Agriculture, Tanjungpura University, Pontianak City, from September 15 to October 30, 2024. The experiment used a factorial completely randomized design with two factors. The first factor was rabbit urine concentration (U) at three levels: u1 = 20 ml/L, u2 = 40 ml/L, and u3 = 60 ml/L. The second factor was the KCl fertilizer dose (K) at three levels: k1 = 0.8 g/plant, k2 = 1.2 g/plant, and k3 = 1.6 g/plant. The results showed no interaction between rabbit urine concentration and KCl fertilizer on the growth and yield of white radish in PMK soil. Individually, rabbit urine at 20 ml/L and KCl fertilizer at 0.8 g/plant gave the best results on radish tuber length. However, no optimal and effective dose was found to significantly improve the growth and yield of white radish in PMK soil.

Abstract

Penelitian ini bertujuan untuk mengetahui dosis terbaik dari penggunaan pupuk kandang kambing dan abu kayu terhadap pertumbuhan dan hasil tanaman lobak pada tanah gambut serta bertujuan untuk mengetahui interaksi antara pupuk kandang kambing dan abu kayu terhadap pertumbuhan dan hasil tanaman lobak pada tanah gambut. Penelitian dilaksanakan di lahan yang berada di Jln. Reformasi, Gg Struktur, Pontianak Tenggara, dimulai pada 8 April 2023 sampai 13 Mei 2023. Penelitian ini menggunakan metode Faktorial Rancangan Acak Lengkap (RAL) yang terdiri dari 2 faktor 3 taraf perlakuan, 4 sampel dan 3 ulangan. Faktor A adalah dosis abu kayu a1 = 30 ton/ha atau setara dengan 200 g/polybag a2 = 40 ton/ha atau setara dengan 300 g/polybag a3= 50 ton/ha atau setara dengan 400 g/polybag dan Faktor K adalah dosis pupuk kandang kambing k1= 10 ton/ha setara dengan 170 g/polybag k2= 15 ton/ha setara dengan 260 g/polybag k3 = 20 ton/ha setara dengan 340 g/polybag. Variabel yang diamati dalam penelitian ini adalah jumlah daun, panjang umbi, diameter umbi, berat segar tanaman, berat segar umbi dan berat kering tanaman. Berdasarkan hasil penelitian penggunaan pupuk kandang kambing dengan dosis 10 ton/ha dan dosis abu kayu 30 ton/ha merupakan dosis yang efisien untuk pertumbuhan lobak pada tanah gambut, karena dengan pemberian dosis pupuk kandang kambing 10 ton/ha memberikan pengaruh berbeda tidak nyata dengan pemberian dosis pupuk kandang kambing 20 ton/ha sedangkan pemberian abu kayu 30 ton/ha berbeda tidak nyata dengan pemberian abu kayu 50 ton/ha. Interaksi antara pupuk kandang kambing dan abu kayu terjadi pada masa pertumbuhan lobak yang dapat dinyatakan pada pengamatan variabel berat kering tanaman.
