Abstract

Ramadhani, F., Yakup, Y., Angraeni, D.E. (2023). The effectiveness of different herbicides in controlling weeds in oil palm (Elaeis guineensis Jack.) plantations. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 570-580).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Oil palm (Elaeis guineensis Jacq.) is one of the most important plantation products in the Indonesian economy. The aimed of this study was to identify the effective herbicide for oil palm farms. Research has been carried out From November 2022 to February 2023, in PT Intimegah Bestari Pertiwi in Kemang, Sanga Desa District, Musi Banyuasin Regency, Indonesia. The method used in this research was randomized block design (RBD) and there were 10 treatments which were repeated three replications. The results showed that herbicide treatment had a significant effect on weed dry weight at 4 MSA, but not at 8 MSA or 12 MSA, according to analysis of variance. Weed vegetation was analyzed before application and the results showed that there were 4 grass weed species, 7 broadleaf weed species and 1 puzzle weed species. The Sum Dominance Ranking (SDR) of the weeds varied. Weeds with SDR more than 5% are revealed by the study, namely in the group of herbaceous leaf weeds there was 1 species namely Ottochloa nodosa 38.4%, in the group of broadleaf weeds there were 3 species namely Clidemia hirta 12.3%, Legazpia polygonoides Beth 10.6%, Borreria alata 6.41%, Melastoma candidum L. 6.14%. thus, there is 1 species of weeds in the puzzle type namely Scleria sumatrensis 9.59%. and based on direct visual observations in the field, the use of herbicides in each treatment showed 0 or no symptoms of poisoning (toxic) to oil palm plants.

Abstract

Zahwa, D.N.A., Lakitan, B., Muda, S.A., Ria, R.P., & Ramadhani, F.  (2023). Red romaine lettuce growth on different shading intensities and organic mulching with watering intensities. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang  21 Oktober 2023. (pp. 135-144).  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Red romaine lettuce (Lactuca sativa L. var. longifolia) is a lettuce variety containing antioxidant, vitamin, and fiber contents that are beneficial in meeting dietary fiber requirements. This vegetable has the potential to be cultivated in suboptimal areas, including urban land. This study was aimed at identifying the impact of several shade intensities and organic mulch with watering intensities on romaine lettuce growth at early vegetative stages. The research followed a split plot design consisting of 2 treatments, namely shade intensity as the main plot (45% shade, 55% shade, and 80% shade) and organic mulch with watering intensities as subplots (without mulch with no intensive watering, organic mulch with no intensive watering, and organic mulch with intensive watering) and repeated 3 times. The results showed that shaded red romaine lettuce (45% shade, 55% shade, and 80% shade) increased growth at early vegetative growth. However, it was not statistically significant. Meanwhile, the application of organic mulch through intensive watering tends to increase shoot and root growth. Differences in shoot and root growth as a result of the treatments applied can also be shown through their visual appearance. Shade and mulch treatments by intensive watering were confirmed to be able to control the microclimate represented through media moisture. The 80% shading and the organic mulch with intensive watering were able to increase media moisture. In conclusion, 80% shading and organic mulch with watering improved red romaine lettuce growth at the early vegetative stage, although recovery to a lower shade is necessary to avoid inhibited root and shoot growth.
