Abstract

Efforts to intensify oil palm (Elaeis guineensis Jacq.) are needed to increase productivity close to the actual production potential of oil palm crops. The productivity and growth of oil palm is partly controlled by the relationship between the top of the plant (the leaf) and the bottom of the plant (root). This study aims to find out the effect of root pruning and the number of fronds on the growth, production and quality of oil palm products. The research was conducted for 12 months from February 2018 to January 2019 in gardens owned by the community of Petapahan Village, Tapung District of Kampar Regency, Riau. The research was conducted experimentally using split plot design which is grouped based on different plant age (5 years, 10 years and 15 years). The main plot is the pruning of oil palm, Normal, Light, and Heavy fronds. The plot is trimming the roots of oil palm 75%, 50% and 25%. The results showed that root pruning and the number of fronds did not affect the interaction of observational premeters. Pruning the roots independently gives a noticeable influence on the content of mesocarp oil. Self-trimming of the fronds has a real effect on the total increase in oil. Plant life has a noticeable effect on enhancement, total oil, mesocarp oil and free fatty acids.

Abstract

Oil palm is a plantation crop that produces vegetable oil, and people highly need it, so it requires efforts to increase its production. One way is by utilizing existing land without having to open new oil palm plantation areas with replanting. This study aimed to analyze the effect of fertilization frequency on different tillage and to get the best fertilization frequency on different tillage on leaf nutrient levels and growth of oil palm plants. This research experimented with a split-plot design (SPD) with a randomized block basic design. The factors tested in this study consisted of the main plot, e.g., tillage (No tillage, 1 time of tillage, 2 times of tillage) and subplots, e.g., the fertilization frequency (D1: 5 times frequency of NPK fertilization D2: 4 times frequency of NPK fertilization D3 : 3 times frequency of NPK fertilization). The two factors were combined, and 12 treatment combinations were obtained. Each treatment combination consisted of 3 groups, totaling 36 experimental units. Each experimental unit consisted of 2 plants, so 72 plants were obtained. The data obtained were analyzed using variance and further tested with the honest significant difference test (BNJ) at the 5% level and advanced test analysis using the Satker application (SAS). This study showed that NPK fertilization with a frequency of 2 times in 2 times tillage increased vegetative plant growth (increased stem circumference). The main plot of tillage two times increased leaf nutrient content (leaf N content) and plant vegetative (plant height gain and stem circumference increase). NPK fertilization with a frequency of 2 times increased plant growth (increased stem circumference).

Abstract

One of the reasons for the low productivity of oil palm is the lack of proper technical culture implementation. The implementation of technical culture practices that can be carried out includes stem mounding by creating mound platforms for the oil palm. This study aims to determine the effect of mound bed height on the growth and development of roots in 10-year-old oil palm plants. The research was conducted experimentally using a Non-Factorial Randomized Complete Block Design with 5 levels of mound bed height: 20 cm, 25 cm, 30 cm, 35 cm, and 40 cm. Each treatment was replicated five times, resulting in 25 experimental units. Each experimental unit consisted of three sample plants, making a total of 75 sample plants. The observed parameters included fresh root weight, dry root weight, the number of primary roots, the length of primary roots, the number of secondary roots, the length of secondary roots, and the number of tertiary roots. The results of the study indicated that the mound bed treatment on 10-year-old oil palm plants in mineral soil, particularly at a height of 40 cm, tended to increase the fresh root weight by 2.45 g, the dry root weight by 0.65 g, the number of tertiary roots by 5.26 strands, the number of primary roots by 2.80 strands, the length of primary roots by 10.0 cm, the number of secondary roots by 2.26 strands, and the length of secondary roots by 2.61 cm.

Abstract

The paddy production is decreasing due to land characteristics that are not suitable for its crop requirements. This study aims to identify the inhibiting factors of growth and production and evaluate land suitability based on the factors that inhibit growth and production of tidal paddy fields. The research method used is a soil survey. Soil sampling points were determined based on the overlay results of the current paddy field map and the map of land and soil units. The suitability assessment of paddy fields is carried out using a matching system in actual and potential conditions. The actual land suitability of all SLH is not current suitable (N1) with a very high Fe inhibiting factor. Limiting factors of Fe content can be overcome by making one-way drainage channels, adding organic matter, liming, fertilizing and or using tolerant varieties. The potential land suitability of all SLH is marginally suitable (S3).

Abstract

Red chilies are one of the horticultural commodities that have high economic value in Indonesia. Red chili production in Indonesia in 2021 will reach 136 million tons, with Riau province experiencing a decline in production which causes a production deficit in the province. To increase production, it is necessary to improve red chili cultivation techniques. The growth of red chili plants is influenced by internal and external factors, including ideal rainfall ranging from 600 mm/year to 1,250 mm/year. Rainfall that is too high can cause air humidity to increase and plants are more susceptible to disease. Red chili plants also require slightly hot daytime temperatures and sufficient water availability. In the rainy season, the risk of red chili crop failure is high because the plants cannot tolerate standing water. Excess water can cause plant root rot and diseases such as bacterial wilt and anthracnose. Therefore, it is necessary to develop red chili cultivation techniques in the rainy season, such as making the right planting schedule, understanding cultivation techniques, and using technical cultural measures such as making higher beds and using appropriate pesticides. With the right cultivation techniques, it is hoped that it can increase farmers' income and welfare. Red chili cultivation can also provide large profits if revenue is high and production costs are low. Therefore, it is important to optimize efforts to increase red chili production by using appropriate cultivation techniques during the rainy season. The aim of this community service activity is to increase public knowledge about cultivating chili plants during the rainy season in Teluk Piyai Pesisir.
