Abstract

Aquatic plant is an important component of a constructed wetland system for treating acid mine drainage (AMD).This study was conducted to investigate the remediation effects of planting three aquatic plants species on AMDquality in simulated wetland systems. Simulated wetland systems were constructed using 10-L plastic containersas growth media comprising mixed-organic substrates and aquatic plant species as planting treatments. Thetreatments involved individual plantings with Fimbristilys hispidula (Vahl) Konth, Mariscus compactus (Retz) Druce,and Typha angustifolia L., and mixed-planting with a combined three-plant species. As the control was the unplantedmedia. The plants were continuously flooded with very acidic AMD collected from a mine pit in PT TambangBatubara Bukit Asam, South Sumatra. During the experiment, the acidity (pH), oxidation reduction potential (Eh),and electrical conductivity (EC) of the flooding AMD were measured after 24 hours of the flooding, and thenbiweekly until the plants entered their reproductive stage. To estimate Fe removed by plants, AMD samples weretaken from both planted and unplanted systems for total dissolved Fe analyses. The data revealed some remediationeffects of planting aquatic plants on AMD in the wetland treatment systems. The presence of plants in the wetlandsystem appeared to induce oxygen diffusion to surrounding roots, which might result in Fe precipitation on rootsurface. Although no differences among planting treatments, Fe removals by plants highly correlated (R2=0.92)with the production of plant biomass.

Abstract

Terung (Solanum melongena) merupakan tanaman hortikultura yang memiliki nilai ekonomi tinggi dan dibudidayakan secara luas. Salah satu kendala budi daya tanaman terung ialah adanya infeksi virus yang menyebabkan penyakit. Pada beberapa pertanaman terung di Bengkulu ditemukan gejala sistemik mosaik kuning yang mirip dengan infeksi Begomovirus pada cabai. Penelitian bertujuan mendeteksi dan mengidentifikasi penyebab gejala mosaik kuning pada tanaman terung di Bengkulu yang diduga disebabkan oleh Begomovirus dan berasosiasi dengan betasatelit. Sampel diambil secara purposive dari pertanaman terung di Kota Bengkulu, Kabupaten Bengkulu Tengah, Kabupaten Bengkulu Utara, Kabupaten Kepahiang, dan Kabupaten Rejang Lebong. Deteksi virus dilakukan dengan metode PCR menggunakan primer universal Begomovirus dan primer spesifik betasatelit serta identitas virus dikonfirmasi dengan perunutan sikuen DNA. PCR dengan primer universal Begomovirus dan betasatelit berhasil mengamplifikasi DNA berturut-turut berukuran ±912 pb dan ±1300 pb dari sampel daun yang bergejala mosaik kuning, malformasi daun, dan penebalan tulang daun. Berdasarkan hasil perunutan DNA sampel dari Bengkulu Utara dan Kepahiang menunjukkan homologi tertinggi berkisar 99% dengan Tomato yellow leaf curl Kanchanaburi virus (TYLCKaV) asal Indonesia, Malaysia, dan Thailand. Hasil deteksi dan identifikasi ini merupakan laporan pertama infeksi TYLCKaV dan asosiasinya dengan betasatelit Begomovirus pada terung di Bengkulu.

Abstract

Taro (Colocasia esculenta L. Schott) is a plant that has an excellent economic and healthy value, as well as a great potential development of Bengkulu coastal area. That is because taro has wide adaptability, and can be consumed both as a staple food and healthy food alternative. This research was conducted to study the vegetative growth of two cultivars of taro given four different doses of nitrogen. This study applied a Randomized Complete Block Design (RCBD) with two factors. The first factor was the cultivar of taro consisted of two levels, namely Taro Satoimo (T1) and the Taro Local (T2). The second factor was the doses of nitrogen fertilizer which consisted of four levels namely: N0 = 0 kg / ha (control), N1 = 50 kg / ha (2.6 g, N2 = 100 kg / ha, and N3 = 150 kg / ha. Thus, obtained eight treatment combinations. Each treatment was repeated three times to get 24 plots. The results showed that based on increased vegetative growth, the cultivar Satoimo has a faster response than local cultivar. Satoimo has demonstrated another advantage because it produced some leaves and number new shoot. The best dose of nitrogen fertilizer on the vegetative growth of taro in the coastal area of Bengkulu is 150 kg/ha.

Abstract

A field trial was conducted to determine the efficiency of AMF inoculation for enhancing growth and yield performance of maize, root colonization, soil available P, and P uptake in Ultisols amended with different P dosages. This experiment was conducted in a 3 x 3 factorial scheme under complete randomized  design with three AMF inoculation methods and three different P levels (0, 60, and 120 kg P2O5 ha-1) in five replications. Data were collected on plant growth, yield parameters, soil available P, P uptake, and root colonization. Results showed that inoculation via seed coating at 60 kg P2O5 ha-1 gave a significant (p<0.05) increase in  growth traits (average of 25%), biomass production, grain yield (average of 30%), soil P availability, P uptake, and root colonization. Inoculation via seed coating combined with 60 produced the same values of all the tested parameters with and seed coating inoculation and soil inoculation at120 kg P2O5 ha-1. Thus, seed coating was as effective tool as soil inoculation for AMF delivery and capable of reducing 50% of P fertilizer use. For these reasons, co-application of P fertilizer and AMF inoculation via seed coating could be practiced to improve corn yields on poor Ultisols.

Abstract

Excessive reliance on synthetic pesticides in modern agricultural systems has caused various serious problems, including pest resistance, ecosystem damage, and threats to human health. Ecology-based Integrated Pest Management (IPM) emerges as a promising alternative approach to address these challenges while enhancing agricultural productivity sustainably. This research aims to analyze ecology-based IPM strategies and evaluate their effectiveness in improving sustainable agricultural productivity. The research method uses a qualitative approach with systematic literature review of scientific publications from 2019 to 2024, case studies of IPM implementation in various countries, and comparative analysis between IPM systems and conventional pest management. Data were collected from 78 reputable journal articles, technical reports from international agricultural organizations, and field practice documentation. The analysis results show that ecology-based IPM implementation can reduce synthetic pesticide use by up to 65 percent while maintaining or even increasing crop productivity by 12 to 18 percent compared to conventional systems. Key components of IPM strategy include systematic pest population monitoring, utilization of natural enemies through conservation and augmentation, crop diversification and rotation to disrupt pest life cycles, use of pest-resistant varieties, habitat manipulation to enhance functional biodiversity, and application of biological and selective pesticides only when necessary based on economic thresholds. IPM implementation faces challenges including higher technical knowledge requirements, time investment for intensive monitoring, and transition periods requiring ecosystem adjustment. However, long-term benefits including ecological sustainability, better soil health, reduced input costs, and agricultural system resilience to climate change make IPM a highly prospective strategy. Policy recommendations include development of farmer training programs, incentives for IPM practice adoption, support for research and development of pest-resistant varieties, and integration of IPM in agricultural education curricula.
