Abstract

The first problem faced in cultivating oil palm is the procurement of seeds. Ultisol soil when used for breeding media has several problems such as having a wet saturation of less than 35% at a depth of 125 cm below the upper limit of the argillic horizon. Ultisol has an acidity level of less than 5.5, low to moderate organic matter and low nutrition. The addition of organic material such as the LCC Mucuna bracteata compost is highly recommended because it will improve the physical, biological, and chemical properties of the soil, so that it increases the availability of nutrients in the soil to be optimal. This study aims to determine the effect of LCC mucuna bracteata compost on ultisol soil medium and determine the dosage/dose of LCC Mucuna Bracteata compost which provides the best growth of oil palm seedlings (Elaeis guineensis Jacq). This research was carried out experimentally with a Completely Randomized Design (CRD), consisting of 5 treatments and 4 replications. The results of this study indicate that distributing doses of 400 g/8 kg of soil improved the physical and chemical properties of the soil and the vegetative growth of oil palm seeds.

Abstract

Matoa fruit is one of the original Indonesian fruits from Papua. Matoa fruit is very popular for its delicious taste and unique fruit aromas such as durian and rambutan. many matoa plants can be found in Pekanbaru with age of 13, so it is necessary to conduct a research on the matoa fruit. The purpose of this study was to determine the maximum weight of fresh fruit and total dissolved solids in red matoa based on the age of fruit collection. The study was conducted with a descriptive analysis. Thirteen year old red matoa plants were studied at Purwo Farm Gardens, Jalan Sri Kurnia, Palas, Agrowisata Village, Rumbai District, Riau. The study was conducted during 4 months from April to July 2020. The results showed the maximum fresh weight of red matoa fruits at the age of fruit collection of 56 days after pollination (DAP). Total dissolved solids (TDS) in red matoa fruit was 56 DAP.
