Abstract

Glyphosate, which has been documented as a contaminant in tea, promotes the proliferation of human breast cancer cells (MCF-7). Tea, on the other hand, includes various antioxidants, including epigallocatechin gallate (EGCG), which may protect against cancer cell proliferation. The purpose of this research is to determine the preventive effect of concentrated brewed green tea on MCF-7 development caused by glyphosate. The glyphosate concentration that promotes MCF-7 development was determined using a serial concentration of glyphosate. Glyphosate concentrations of up to 64 mg/L were shown to have no effect on MCF-7 cell proliferation. Concentrated brewed tea and EGCG 200 mg/L have the potential to suppress MCF-7 cell proliferation in the presence of glyphosate up to 512 mg/L. The combination of glyphosate and concentrated brewed tea or EGCG protects against glyphosate toxicity via altering the expression of tumor suppressor protein (p53).

Abstract

Forty percent of the total oil palm plantation area in Indonesia belong to the smallholder palm oil plantations. The productivity of smallholder oil palm plantations is still relatively low, only around 2-3 tons of CPO/ha/year under PBN dan PBS. The aim of this study is to identify internal dan external constraints that cause low productivity of smallholder oil palm dan the recommended solutions. This research was taken in Sanggau dan Sintang Regencies which are the largest areas of smallholder palm oil plantation in West Borneo. Data obtained were analyzed by SWOT. The results showed that there were four main strategies to increase productivity dan solve problems on oil palm plantation in Sanggau dan Sintang Regencies, namely, 1) intensifying technical training of oil palm cultivation to increase the farmers’ knowledge dan capabilities, 2) increasing the role dan ability of farmer institutions both farmer groups dan ‘koperasi’ in establishing cooperation with stakeholders dan in marketing fresh fruit bunch (FFB), 3) escalating the awareness dan understanding of farmers in using digital information technology to support their business activities on oil palm, dan 4) strengthening the government protection against middlemen.
