Abstract

Penggunaan tanah aluvial sebagai media tanam memiliki beberapa tantangan, seperti struktur tanahnya yang padat dan kandungan hara yang rendah. Terlepas dari masalah ini, upaya telah dilakukan untuk memperbaiki tanah aluvial dengan menambahkan bokashi ampas tebu dan pupuk NPK. Penelitian ini dilakukan di Jalan Reformasi Gg. Struktur Untan. Penelitian ini bertujuan sebagai berikut: (1) mengetahui adanya interaksi antara bokashi ampas tebu dan NPK terhadap pertumbuhan dan hasil kubis bunga di tanah aluvial dan (2) mendapatkan dosis terbaik bokashi ampas tebu dan NPK untuk pertumbuhan dan hasil kubis bunga di tanah aluvial. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktor perlakuan, yaitu faktor bokashi ampas tebu (K) dan faktor pupuk NPK (P). Setiap faktor memiliki tiga taraf perlakuan, dan setiap perlakuan diulang tiga kali dengan empat sampel per perlakuan. Faktor ampas tebu bokashi (K) meliputi perlakuan sebagai berikut: k1 = 15 ton/ha, k2 = 20 ton/ha, dan k3 = 25 ton/ha. Faktor pupuk NPK (P) meliputi perlakuan sebagai berikut: P1 = 200 kg/ha, P2 = 300 kg/ha, dan P3 = 400 kg/ha. Beberapa variabel yang diamati dalam penelitian ini antara lain jumlah daun, umur muncul bunga (HST), diameter tanaman (cm), berat kering tanaman (g), berat segar tanaman (g), berat segar tanaman (g), volume akar (cm3), dan umur panen (HST). Hasil penelitian menunjukkan tidak ada interaksi antara bokashi ampas tebu bokashi dan pupuk NPK terhadap pertumbuhan dan hasil kubis bunga di tanah aluvial. Namun, pemberian ampas tebu bokashi dengan dosis 20 ton/ha memberikan hasil terbaik untuk berat segar tanaman dan  krop kubis bunga di tanah aluvial. Namun pemberian pupuk NPK dengan berbagai dosis tidak memberikan hasil yang terbaik untuk pertumbuhan dan hasil kubis bunga di tanah aluvial.  Kata kunci : Tanah aluvial, Bokashi Ampas tebu, kubis bunga, NPK

Abstract

Tanaman lobak (Rhaphanus sativus L.) adalah sayuran berumbi asal Asia Barat dan Eropa, dengan varietas putih paling umum dikonsumsi. Umbinya kaya zat dan vitamin, sehingga dibudidayakan sebagai sayuran dan obat. Tanah podsolik merah kuning (PMK) memiliki kendala seperti struktur menggumpal, agregat tidak stabil, permeabilitas rendah, miskin unsur hara makro (N, P, K, Ca, Mg) dan mikro (Zn, Mo, Cu, B), serta bahan organik. Bokasi paitan digunakan untuk memperbaiki kerusakan tanah akibat pupuk anorganik dan meningkatkan sifat fisik, kimia, dan biologi tanah PMK. Penelitian bertujuan menentukan dosis terbaik bokasi paitan dan pupuk NPK terhadap pertumbuhan lobak di tanah PMK. Lokasi penelitian di Jalan W.R. Supratman Pontianak selama ±4 bulan, menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan dua faktor: bokasi paitan (30, 40, 50 ton/ha) dan pupuk NPK (300, 400, 500 kg/ha). Setiap kombinasi diulang 3 kali dengan 4 sampel tanaman, total 108 tanaman. Variabel yang diamati meliputi jumlah daun, berat segar dan kering umbi, diameter, serta panjang umbi. Hasil menunjukkan interaksi signifikan antara bokasi paitan dan pupuk NPK terhadap berat kering tanaman. Kombinasi bokasi 40 ton/ha dan NPK 500 kg/ha menghasilkan berat kering tertinggi, serta efisien pada variabel umbi lainnya.

Abstract. Supriyanto, Ruliyansyah A, Arifin N, Pramulya M, Sulistyowati H. 2025. Assessment of agronomic practices among natural rubber farmers in Sintang District, West Kalimantan, Indonesia. Asian J Agric 9: 754-765. Smallholder rubber farmers play a crucial role in maintaining the sustainability of the rubber sector in Indonesia; however, their productivity and management practices remain suboptimal. This study assessed the agronomic practices of 470 smallholder rubber farmers in Sintang District, West Kalimantan, Indonesia, using a descriptive-quantitative approach. Data were collected through structured interviews and analyzed using descriptive statistics and Pearson correlation to examine relationships among human resource capacity, socio-economic conditions, and agronomic performance. The results indicate that the majority of farmers are in the productive age group, have low to moderate education, and rely on rubber farming as their primary livelihood. However, farmers tend to prioritize routine operational tasks, such as tapping and latex collection, while key agronomic practices that require more technical knowledge and capital—such as fertilization, the use of certified planting materials, and pest and disease control—remain under-implemented. Correlations indicate that education and access to extension services are positively correlated with the adoption of better agronomic practices, including the use of certified seeds, recommended plant spacing, and proper fertilization. Social roles and group participation also show significant relationships with collective agronomic behavior. These findings highlight the importance of strengthening farmer capacity and institutional support to promote productive and sustainable rubber cultivation among smallholder farmers in Sintang District, West Kalimantan, Indonesia.

Abstract

Inventory and Analysis of Barriers to Increasing Areca Nut Productivity in Sungai Kakap District, Kubu Raya Regency. Areca nut productivity in Kubu Raya Regency is relatively low, at around 0.86 tons/ha, compared with the national average of 1.53 tons/ha. This indicates that there are still many problems in areca nut farming in Kubu Raya Regency. Based on this, research is needed to inventory and analyze obstacles to increasing areca nut productivity, with the results informing recommendations for policy interventions in Kubu Raya Regency. The research was conducted in Punggur Besar Village, Sungai Kakap District, Kubu Raya Regency, and is a descriptive study using a survey method with respondents as research objects. Primary data were collected using a questionnaire to obtain systematic, objective information on farmer characteristics, technical, economic, and external obstacles experienced in running areca nut farming, while secondary data were obtained from relevant agencies and the literature. The results of the study concluded that areca nut farming in Sungai Kakap District, Kubu Raya Regency is still faced with various obstacles, namely: (1) farmers' limited access to information and technology about good and correct areca nut cultivation, (2) farmers can only sell dried areca nuts to collectors at low prices, (3) farmers do not have access to other sources of financing besides their income, and (4) the role of institutions has not been fully felt by farmers, there has been no special guidance and ongoing technical assistance regarding areca nut farming including its financing.

Abstract

Screening of Ganoderma Antagonistic Fungi from Palmae Roots in Kubu Raya Regency, West Kalimantan, Indonesia. Basal stem rot (BSR) disease, caused by the pathogen Ganoderma sp., is the most important disease in palms (Arecaceae, formerly known as Palmae). To date, there is no effective method for controlling Ganoderma. In oil palms, several methods developed can only slow the rate of infection or extend the plant's productive period. Biological control is an alternative method for controlling Ganoderma and is currently under development. However, the development of biological control is hampered by its limited distribution. The most feasible approach is to identify effective indigenous antagonists from the rhizosphere of palms and develop methods for their utilization. This is because the palm family is a group of plants with high species diversity, so it is suspected that they also have a high diversity of rhizosphere fungi. Therefore, it is suspected that there are fungi antagonistic to Ganoderma that can be used as biological control agents against Ganoderma sp. This effort can be done by isolating and screening microorganisms from the rhizosphere of palm plants for their ability to act as antagonists against Ganoderma, and testing their activity in the rhizosphere of palm plants under various combinations of environmental factors thought to support their effectiveness in controlling Ganoderma. Specifically, this research aims to identify Ganoderma antagonists from the rhizosphere of palm plants in West Kalimantan that are effective in controlling BPB disease. The research has been conducted by isolating and testing the ability of fungi from the roots of palm plants in West Kalimantan in controlling Ganoderma sp. The results showed that 50.97% of fungi isolated from palm roots inhibited Ganoderma growth in vitro, with inhibition ranging from 70% to 83%. Given this ability, further testing is needed to determine the effectiveness of these fungi in controlling stem rot disease caused by Ganoderma in palm plants.
