Abstract

Sweet corn is a high-value horticultural commodity with steadily increasing market demand. This study aimed to evaluate the production of sweet corn under different plant spacing and bokashi application. The research was conducted at the Horticultural Experimental Garden of Politeknik Negeri Lampung from July to October 2024, using a two-factor Randomized Complete Block Design (RCBD) with three replications. The first factor was plant spacing, consisting of three levels: 100 cm × 20 cm (JT1), 80 cm × 20 cm (JT2), and 60 cm × 20 cm (JT3). The second factor was bokashi application, also consisting of three levels: no bokashi (B0), 2.5 kg/m² bokashi (B1), and 5.0 kg/m² bokashi (B2). The results indicated that planting distance had a significant effect on all observed parameters. Bokashi application significantly influenced all observed parameters except stem diameter and cob diameter. No significant interaction was observed between planting distance and bokashi application. The 80 cm × 20 cm planting distance produced the highest yield, reaching 14.25 tons/ha. Bokashi application improved plant growth and yield compared to the control.

Abstract

Farmers' dependence on chemical fertilizers remains a major problem in Indonesia's agricultural system, including in West Tulang Bawang Regency. The high price of chemical fertilizers and their negative impact on soil fertility have prompted the need for innovative, environmentally friendly, and sustainable alternatives. One solution is bokashi biofertilizer. This activity aims to enhance farmers' knowledge and skills in producing and utilizing bokashi biofertilizer independently, thereby reducing their dependence on chemical fertilizers and increasing the efficiency of agricultural waste utilization. The community service activity was carried out using a participatory method through several stages: situation analysis, outreach, hands-on bokashi production, and evaluation through pre- and post-tests. The materials used included straw, husks, livestock manure, bran, water, and EM4 solution, using simple tools easily accessible to farmers. The results of the activity showed an increase in participants' knowledge and skills. The average pre-test score of 55% increased to 85% in the post-test. This activity also had positive socio-economic impacts, including increased farmer awareness of environmentally friendly agricultural practices, the formation of group initiatives to produce bokashi together, and savings of up to 30% on chemical fertilizer costs in the following planting season. Farmers demonstrated a positive attitude and commitment to continuing independent bokashi production. This activity contributed to the sustainability of the community empowerment program by promoting farmer independence, enhancing more productive organic waste management, and fostering the creation of a sustainable agricultural system in West Tulang Bawang Regency. Ketergantungan petani terhadap pupuk kimia masih menjadi persoalan utama dalam sistem pertanian di Indonesia, termasuk di Kabupaten Tulang Bawang Barat. Harga pupuk kimia yang tinggi serta dampak negatifnya terhadap kesuburan tanah mendorong perlunya alternatif inovatif yang lebih aman bagi lingkungan serta berkelanjutan. Biofertilizer bokashi menjadi salah satu solusi yang dapat dipilih. Kegiatan ini bertujuan untuk meningkatkan pengetahuan dan keterampilan petani dalam memproduksi serta memanfaatkan biofertilizer bokashi secara mandiri, guna mengurangi ketergantungan terhadap pupuk kimia dan meningkatkan efisiensi pemanfaatan limbah pertanian. Kegiatan pengabdian dilaksanakan dengan metode partisipatif melalui beberapa tahapan, yaitu analisis situasi, sosialisasi dan penyuluhan, praktik langsung pembuatan bokashi, serta evaluasi melalui pre-test dan post-test. Bahan yang digunakan meliputi jerami, sekam, kotoran ternak, dedak, air, dan larutan EM4 dengan alat sederhana yang mudah dijangkau oleh petani. Hasil kegiatan menunjukkan adanya peningkatan pada aspek pengetahuan dan keterampilan peserta. Nilai rata-rata pre-test sebesar 55% meningkat menjadi 85% pada post-test. Kegiatan ini juga memberikan dampak sosial ekonomi positif, antara lain meningkatnya kesadaran petani terhadap praktik pertanian ramah lingkungan, terbentuknya inisiatif kelompok untuk memproduksi bokashi bersama, serta penghematan biaya pupuk kimia hingga 30% pada musim tanam berikutnya. Petani menunjukkan sikap positif dan berkomitmen untuk melanjutkan produksi bokashi secara mandiri. Kegiatan ini berkontribusi terhadap keberlanjutan program pemberdayaan masyarakat dengan mendorong kemandirian petani, pengelolaan limbah organik yang lebih produktif, serta terciptanya sistem pertanian yang berkelanjutan di Kabupaten Tulang Bawang Barat.

Abstract

Shallot (Allium ascalonicum L.) is an important horticultural commodity that contributes significantly to Indonesia's economy. However, its production declined in 2022–2023 compared to 2021. Fertilization plays a key role in improving soil fertility and supplying nutrients for optimal plant growth. This study aimed to assess the growth and yield response of the Brebes shallot variety to various doses of bokashi fertilizer and to determine the most effective dose. The experiment used a Randomized Complete Block Design (RCBD) with one factor: bokashi dosage, consisting of six treatments—B0 (control), B1 (1 kg/m²), B2 (1.5 kg/m²), B3 (2 kg/m²), B4 (2.5 kg/m²), and B5 (3 kg/m²). Each treatment was replicated four times with ten plants per replication, totaling 280 experimental units. The results indicated that bokashi application significantly affected leaf length, leaf diameter, bulb length, bulb diameter, fresh and dry bulb weight, as well as total yield per clump. The highest growth and yield were observed at the 3 kg/m² dosage. Thus, bokashi at 3 kg/m² is considered the most effective dose for improving the growth and productivity of the Brebes shallot variety.
