Abstract

Palm oil production in Indonesia must be optimized to meet world market demands. The steeper the slope of the land, the more erosion and weed growth will occur. This can result in disrupted oil palm growth due to erratic competition, air, and light between oil palm and weeds around the plant. This study aims to determine the relationship between the slope of the land with the production level of Fresh Fruit Bunches of oil palm in the PT. Bina Pratama Sakato Jaya Unit Kiliran Jao Sijunjung Regency. The research is in the form of a survey with a purposive random sampling method. Observation parameters consisted of the weight of fresh fruit bunches, the diameter of stem circumference, and plant height. Data processing using a simple linear regression method. The plantation area of ​​PT. Bina Pratama Sakato Jaya is currently 4,678.79 Ha. Slope significantly affects the production of oil palm Fresh Fruit Bunches (FFB). The highest average production was obtained on flat (0-3%) and gentle slopes (3-8%), and the lowest average production on slopes (15-30%) and very steep (30-45%)

Abstract

Currently, the government continues to encourage the development of oil palm plantation areas with the aim of boosting domestic economic activity. Nagari Lubuk Karak has a large area of land and has the potential to be developed into plantations, especially oil palm plantations. This regency has a land area of 1056 ha. Therefore, an evaluation of land suitability needs to be carried out in order to know the actual and potential land suitability class recommendations for oil palm plantations in that village. The stages in the research included secondary data collection, pre-survey, main survey and soil analysis in the laboratory. Land suitability classification is done by matching method. From the research results it is known that the limiting factors in the actual land suitability class at the study site were temperature, water availability, nutrient retention, and erosion hazard. After improvements have been made with good land management, the land suitability class can be increased with a potential land suitability class, which was previously classified as S3, increased to S2, and previously classified as S2, can be increased to S1. Thus, to obtain good oil palm growth in this region, it is necessary to improve the limiting factors on each land.

Abstract

Community service is important to do in order to develop the order and standard of living of the people in an area. One of them is in Nagari Sungai Kambut where many of the residents are not yet working or not working and some are only taking care of the household. In fact, when viewed from its natural potential, the Nagari Sungai Kambut region has quite a large potential for productive land, including the home yard. Therefore, dedication is carried out in the form of assistance in optimizing the use of the home yard for planting fruits. The hope is to increase the knowledge and improve the skills of the local population. The fruit produced can also be a source of income, apart from just for self-consumption. Service activities begin with socialization, counseling and followed by assistance in planting fruit trees. Farmers are guided and assisted by the team so that when there are problems they can be immediately resolved. During the socialization, the residents actively raised various questions, both from how to plant, maintain and even post-harvest. Seeing the enthusiastic response of the community shows that this service program has been able to increase knowledge about the importance of using the home yard, especially for planting fruits. Overall, a series of community empowerment activities through planting fruits in order to optimize the use of the home yard has given positive impact on the community. Appropriate cultivation techniques will provide benefits to society by increasing crop productivity. The product can be consumed or sold and participate in protecting the environment so that it remains sustainable. The enthusiasm of community was the evidence of their high curiosity and indicator of the successfulness of this activity.

Abstract

Coffee is one of the plantation commodities that has significant economic value. A factor that needs to be considered in coffee plant cultivation is good planting media composition. This study aims to determine the effect of planting media composition on the growth of robusta coffee seedlings. This study used a Completely Randomized Design with treatments M0= Soil: 100%, M1= Soil: 50% + Coffee Husk Compost: 25% + Rice Husk: 25%, M2= Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25%, M3= Soil: 25% + Coffee Husk Compost: 25% + Rice Husk: 50%. The analyses conducted were compost analysis and initial and post-incubation soil analysis. Observation data were analyzed using the F test followed by DNMRT at the 5% level. The research results show that the provision of coffee husk compost and rice husks affects the chemical properties of the soil and the growth of coffee seedlings. The planting media composition of Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25% proved to increase the pH of the planting media from 5.5 to 6.6, increase in total N-value from 0.2% to 0.5%, available P from 18.6 ppm to 38.5 ppm and the soil CEC from 7.6 me/100g to 36.6 me/100g. This planting media composition also makes it possible to enhance the growth of robusta coffee seedlings in plant height, stem diameter, number of leaves, leaf width, and root volume. Thus, this planting media composition is a suitable medium for the growth of robusta coffee seedlings.
