Abstract

The application of agroforestry landscape pattern for rubber plant with cayenne pepper plant has an effect on productivity and land use level compared to monoculture system. This reaserch aims to obtain data on the production of cayenne pepper plants in rubber plants agroforestry system and compare it with monoculture systems. The research was located in Sumber Sari Village, Sebulu District, Kutai Kartanegara Regency with two planting system treatments (P), it’s monoculture system planting (p1) and rubber plants agroforestry system (p2) with 6 plots as replicates each. The variables measured were the production of cayenne pepper plants until the 5th (fifth) harvest based on the average sample. Data were analyzed using the Independent Sample t-test with a significant level (α) of 5%. Production of cayenne pepper plants in rubber plants agroforestry system reached 2.32 Mg.ha-1 which was greater than monoculture system with a production of 1.46 Mg.ha-1 with F-Count 1.74 and F- Table 7.15. This is due to the growth environmental conditions and photosynthetic efficiency, with a higher daily temperature of 300C in monoculture system, it will slow down of photosynthesis and accelerate respiration rate, whereas the daily temperature in an agroforestry planting system with rubber plants is only 260C, so that the photosynthesis rate is higher than respiration rate, because the optimum temperature for cayenne pepper plants photosynthetic is 21-270C. Cayenne pepper plants in agroforestry landscape pattern for rubber plant were able to produce better yields than monoculture planting systems based on two average similarity test.

Abstract

Oil palm is the plant that produces the highest oil among other plants and the level of cholesterol compounds contained in palm oil is relatively lower compared to other plants. Therefore, this study aims to determine the content of compounds contained in oil palm plants using the GC-MS instrument. The results of the GC-MS analysis on the sample carried out showed that 14 peaks were detected representing 11 compound components. Based on the analysis of 11 compound components, three compounds were found that had the most significant percent area value, namely the compound 2-Propenoic acid, 1,7,7-trimethylbicyclo[2.2.1]hept-2-yl ester, exo- by 39.06%; Isobornyl propionate compound by 16.21% and the last compound is Cyclopentanecarboxylic acid, 3-methylene-,1,7,7-trimethylbicyclo[2.2.1]hept-2-yl ester (CAS) CYCLOPENTANIC with a percent area value of 12.99%.
