This final project research was conducted at the Kuala Pesilam Balai Gajah estate, Division I, PT. Bahruny, North Sumatra Province. This study took place from July to July 2021. This study aims to determine the pattern of weed control in the circle on production as well as rainfall and rainy days. This study uses a descriptive method by collecting secondary data from the garden: rainfall and production data. The results of this study can indicate that Indonesia's unstable palm oil production is caused by several factors, namely genetic factors, biotic factors (weeds) and abiotic factors (rainfall and rainy days). Production in 2020 is the highest production of oil palm for 4 years (2017-2020) with a total production of 5,971,760 Kilograms with an area of 336.96 hectares. The amount of rainfall is 2371 mm and rainy days is 117 days with weed control patterns on the disk carried out 4 times a year. Production in 2018 was the lowest production of oil palm for 4 years (2016-2020) with a total production of 4,032,338 kg, with an area of 267.96 Ha. The amount of rainfall is 1854 mm and rainy days is 112 rainy days with weed control patterns on the disc 2 times a year. The optimal rainfall for the growth and production of oil palm plants is 2,000 mm, but with 1846 mm of rainfall it does not mean it is not good for the growth and production of oil palm plants as long as there is no water deficit, so this rainfall is still included in the criteria for growing oil palm.

Mitochondrial heat shock proteins of HSP70 family support protein homeostasis in mitochondria under normal and stress conditions. They provide folding and complex assembly of proteins encoded by mitochondrial genome, as well as import of cytosolic proteins to mitochondria, their folding and protection against aggregation. There are reports about organ-specificity of mitochondrial HSP70 synthesis in plants. However, tissue specificity of their functioning remains incompletely characterized. This problem was studied for mitochondrial AtHSP70-10 in Arabidopsis thaliana seedlings using a transgenic line with uidA signal gene under normal conditions, as well as high temperature and water deficit. Under normal conditions, histochemical GUS-staining revealed the expression of AtHSP70-10 in cotyledon and leaf hydathodes, stipules, central cylinder in root differentiation and mature zones, as well as weak staining in root apex and root-shoot junction zone. RT-PCR analysis of wild-type seedlings exposed to 37°C showed rapid upregulation of AtHSP70-10, which reached the highest level within 2 h. In addition, the gradual development of water deficit for 5 days caused an increase in transcription of this gene, which became more pronounced after 3 days and reached a maximum after 5 days of dehydration. Histochemical analysis showed complete preservation of tissue localization of AtHSP70-10 expression under both abiotic factors. The data obtained indicate the specific functioning of mitochondrial chaperone AtHSP70-10 in certain plant cellular structures.

Response To Water

Yield improvement of durum wheat is considerably limited by the expression of environmental abiotic factors. Water deficits are one of these limiting factors. Plants develop various strategies to tolerate the effects of water deficit. Some of such mechanisms might occur in the root and stem systems. The present study aimed to investigate some anatomical traits contributing to the drought tolerance in the durum wheat. The anatomical variations of the meristem of roots and stems, as a response to water deficit, were evaluated. The results indicated that the enhancement of the intensity of water deficit was accompanied by profound structural changes in the piliferous zone of roots. Water deficit caused a significant decrease in the diameter of the newly formed adventitious roots, which can be explained by a reduction in the thickness of the cortical parenchyma, through the reduction of cell size. This action was usually a contrary effect in the principal adventitious roots. The study also showed that increasing the intensity of water deficit reduced the diameter of vessels in the primary xylem, thereby increasing the hydraulic resistance of roots and lowering the flow of sap.

Oil palm plantations are strategic commodities in the national economy and public welfare. Smallholder oil palm plantations as part of the palm oil commodity supply chain currently face business sustainability issues. This study aims to analyze the sustainability of community oil palm plantations based on index assessment using the Rap-Palmoil method through the Multidimensional Scaling (MDS) method. Multidimensional analysis of MDS in terms of economic, social, environmental, institutional, and technological dimensions as aspects examined in this study. This research was conducted in two regencies of oil palm plantations in a broad area of ​​land in Jambi Province, namely Muaro Jambi Regency and Merangin Regency. The data used are primary and secondary data, primary data are obtained from interviews with farmers while secondary data are obtained from the Central Statistics Agency, Plantation Service, and literature that supports this research. Respondents in this study were 99 farmers selected purposively. The results of the multidimensional sustainability analysis of the Jambi Province oil palm plantation sustainability index were 57,79 included in the quite sustainable category. While the results of the sustainability index analysis for the five dimensions are 54,11 (economy), 66,83 (social), 58,64 (environmental), 46,40 (institutional), 59,02 (technology). All dimensions are overall included in the "moderately sustainable" category except the institutional dimension in the "less sustainable" category. The sustainability of oil palm plantations in each dimension has a different sustainability index so that different policies are needed to evaluate the sustainability of community oil palm plantations in Jambi Province.
