Abstract

Salah satu cara untuk memperbaiki sifat fisika, kimia, dan biologi tanah yaitu dengan penerapan sistem pertanian organik yang memanfaatkan bahan-bahan alami yang tersedia di alam. Salah satu solusi yang dapat diterapkan yaitu dengan menggunakan biofertilizer sebagai alternatif untuk mengganti penggunaan pupuk anorganik. Penelitian ini bertujuan untuk: 1) mempelajari respon produksi tiga kultivar bunga kol yang dibudidayakan secara organik akibat aplikasi biofertilizer, 2) mempelajari konsentrasi biofertilizer yang terbaik dalam meningkatkan produksi bunga kol, 3) mempelajari interaksi antara kultivar dan konsentrasi biofertilizer terhadap produksi bunga kol. Penelitian ini dilaksanakan di Politeknik Negeri Lampung dari Juni sampai November 2021. Percobaan disusun secara faktorial dalam Rancangan Acak Kelompok (RAK) dengan ulangan 3 kali. Faktor pertama yaitu 3 kultivar bunga kol yang terdiri atas Diamond 40, PM 126, dan Snow white. Faktor kedua yaitu level konsentrasi biofertilizer dengan 4 taraf yang terdiri atas 0%, 25%, 50%, dan 75%. Homogenitas data diuji dengan Uji Barlette, dan aditivitas data dengan Uji Tukey, kemudian dialkuakan analisis sidik ragam, dan dilanjutkan dengan uji Beda Nyata Terkecil (BNT) pada taraf 5%. Hasil penelitian menunjukkan bahwa 1) aplikasi biofertilizer nyata meningkatkan bobot dan diameter bunga tanaman kembang kol; 2) dosis terbaik yang menghasilkan produksi tertinggi yaitu konsentrasi 25 %; dan 3) Kultivar Snow White direkomendasikan untuk dibudidayakan secara organik.

Abstract

Aluminum stress is a limiting factor for crop production on acid dry land with a low pH. The objectives of this study were to evaluate aluminum-tolerant upland rice varieties in acid dry land. The study was carried out using a completely randomized block design (RCBD) consisting of 8 varieties, namely IR64, Inpago 7, Dodokan, Dod-Pup1, Situ Bagendit, Situ Bg-Pup1, Batur, Batur-Pup1, and 4 strains, namely 19 (PB5)-2, 20 (PB8)-1, 21 (PB15)-1, and 22 (PB16)-1. The results showed that the Situ Bagendit variety with the Pup-1 locus gave the highest yield per plot compared to other varieties and lines, namely 287.5 g. These results also correlate with the ability of the variety to withstand aluminum stress, with a tolerance value of 3.00 (rather tolerant).

Abstract

Fly ash is the residue of coal combustion that can potentially be an ameliorant. Unfortunately, its use is limited by government regulations that are classified as hazardous and toxic materials. This study examines the effectiveness of fly ash and cow manure as an ameliorant for Ultisols. The experiment was carried out by two factors, i.e., the dose of fly ash, namely 0, 50, 100, and 150 t/ha, and the quantity of cow manure, i.e., 10, 20, and 30 t/ha. The results show that fly ash and cow manure could be ameliorants for low-pH soils such as Ultisols. The suitable dose of fly ash and cow manure as ameliorants in this study are 50 t/ha and 20 t/ha, respectively. Increasing the amount of fly ash caused a decrease in the growth of water spinach, plant height, number of leaves, fresh plant weight, root length, and dry weight of the root. In addition, fly ash increased pH 6.66-7.30, total P 31.74-52.21 mg/100 g, and total K 16.19-25.75 mg/100 g.

Abstract

Kailan is a leaf vegetable that has high nutrition and economic value and can be cultivated using DFT hydroponic system to support its productivity. The aims of this study to determine the influence of the types of growing media and differences in varieties and the interaction of the two on the growth in DFT hydroponic system. The study used a factorial complete randomized design consisting of the first factor wass the variety, namely Winsa variety (V1) and Full White variety (V2), the second factor was the type of growing media, namely rockwool (M1), sponge (M2), coco fiber (M3), and coco chip (M4). The results showed there was no interaction between the variety and the growing medium but there was a significant result of variety on the height parameters. The growing medium showed a significant result on the number of leaves, relative growth rate, net assimilation rate, root shoot ratio, and wet weight of kailan plants parameters. Cocochip media and Winsa varieties provide the best growth of kailan plants in all observation parameters.

Abstract

Organic fertilization of cow manure bokashi and inorganic fertilizer SP-36 is an alternative to improve soil fertility in red-yellow podzolic soil. However, due to its slow availability, the application of this fertilizer from previous plantings still leaves residue to improve the quality of mung beans in subsequent plantings. The aims of the study were to determine: 1) The effect of various residual doses of bokashi fertilizer on the growth and yield of mung bean. 2) The effect of various residual doses of SP-36 fertilizer on the growth and yield of mung bean. 3) Interaction of various doses of bokashi and SP-36 fertilizer residues on the growth and yield of mung bean. The research was carried out in the experimental garden of the Dharma Wacana College of Agricultural Sciences, Margorejo Subdistrict, Metro City, from February to April 2021. The study used a Complete Randomized Block Design which was arranged in a factorial manner with three replications. The first factor was residues of cow manure Bokashi fertilizer (B) which consisted of three levels, namely dose of 5 tons/ha (b1), 10 tons/ha (b2), and 15 tons/ha (b3). The second factor was SP-36 (P) fertilizer residue which also consisted of three levels, namely dose of 150 kg/ha (p1), 200 kg/ha (p2), and 250 kg/ha (p3). The results showed that residues of various doses of bokashi and SP-36 had no significant effect. No interaction was found between residues of bokashi fertilizer and SP-36 on the growth and yield of mung bean. However, mung beans show a fairly good production.

Abstract

OPT problems are still a major obstacle to organic rice cultivation due to limited understanding and control skills. The aim of implementing community service activities is to provide additional skills and insight regarding OPT control technology with local biological agents to solve the problem of organic rice farming in Bumiagung village, Tegineneng, Pesawaran. Technology transfer activities regarding the application of control with local biological agents to solve the problem of pest attacks on organic rice plants were carried out in Bumiagung Village, Tegineneng, Pesawaran which were carried out in June - October 2022 to the Progressive Organic Farmers Community. The stages of the activity are carried out in stages through conducting surveys, providing material, pre-testing, training and mentoring, post-testing, monitoring, and evaluation at the end of the activity. Before the activity begins, a survey is carried out to analyze conditions and problems and analyze the solutions needed for these problems. Farmers need to gain more knowledge and skills in managing pests that attack their land. The controls that are often used are vegetable pesticides and refugia. From the final evaluation results, the analysis shows that farmers realize that control with biological agents is effortless, inexpensive, and synergistic in supporting organic farming.

Abstract

The presence of weeds can result in a reduction in the productivity of rubber plants, necessitating the implementation of control measures. Among the various control methods, the use of herbicides derived from paraquat dichloride has been identified as a more effective and efficient approach in terms of cost and time. However, the application of weed control measures can lead to alterations in the structure and composition of weeds. The objective of this study was to ascertain the prevalence of weeds and the impact of paraquat dichloride herbicide on the composition of weeds in rubber plantations. This study employed a randomized group design with six treatments and four replications. The treatments consisted of doses of paraquat dichloride, including 310.5 g/ha (P1), 414 g/ha (P2), 496.8 g/ha (P3), 621 g/ha (P4), mechanical control (P5), and control (P6). The results demonstrated that paraquat dichloride herbicide was efficacious in the control of weeds with a rapid onset, yet exhibited a limited duration in comparison to crop-translocated herbicides. This was evidenced by the diversity of weed species dominance at SDR 4 WAA < 8 WAA < 12 WAA. The application of paraquat dichloride herbicide and mechanical control were found to induce alterations in weed composition.
