Abstract

Mucuna bracteata is a type of Leguminosae Cover Crop (LCC) which is widely used in Indonesian plantations. The advantage of Mucuna bracteata is that it grows fast. Based on this, a study was conducted to see the rate of difference in the number of internodes planted which could accelerate the growth and development of Mucuna bracteata. The research was carried out in the practical garden area of ​​the Medan Agricultural College of Agribusiness (STIPAP). The research was conducted from May to June 2020. This study used a non-factorial randomized block design (RBD), which consisted of 1 treatment with 4 levels, namely R0 (1 rolled segment), R1 (2 rolled sections), R2 (3 rolled humps), R3 (4 rolled humps) and with 5 repetitions. The results showed that the treatment of R2, namely 3 bundles of rolled knuckles, gave the best effect on the parameter increase in tendril length, namely 89.66 cm, the increase in the number of tendrils, namely 6.38, the increase in the number of leaves, namely 12.50 strands, the increase in the number of segments, namely 11.32 pieces, and the measurement of the root volume, namely 13.00 ml. The treatment of the number of bunded knots had a significant effect on the parameters of tendril length, number of tendrils, number of leaves, number of internodes, and volume of roots.

Abstract

The concern of oil palm empty fruit bunches (OPEFB) utilization in the rubber field that potential to be a host of white root disease needs to be deeply investigated. The objective of this study was to assess the bacteria on the surface of OPEFB that able to inhibit the growth of R. microporus fungi. The antagonistic assay of eight isolates of bacteria against R. microporus fungi was conducted in the Plant Protection Laboratory of Sungei Putih Research Centre. The isolates were isolated from the surface of OPEFB applied in the rubber field. Nutrient agar (NA) was employed in the isolation and purification of bacteria. The antagonistic assay was carried out in vitro using the dual culture method. The observation was performed on 2, 4, 6, and 8 days after incubation (DAI). The result indicated that the eight isolates have varied in inhibition ability of R. Microporus fungi. The initial inhibition was started since 2 DAI particularly in the isolates B2, B3, B4, and B7. The percentage of inhibition were 30%, 60%, 65% dan 69% respectively. Until 8 HSI, the isolates B2, B3, B4, B6, B7, and B8 were still inhibiting the growth of R. microporus fungi > 80%. The isolates B3 and B4 showed the best performance in fungi inhibition with the percentage > 95%. Whereas, the ability of inhibition of the isolates B1 and B5 were very low as < 50%. The existence of such antagonistic bacteria perhaps led to OPEB was not role as the host of white root disease while applied in the rubber field

Abstract

In several years ago, the natural rubber price shows a negative trend. This condition make a rubber smallholder face difficulties in life. This paper study the efforts made by rubber smallholder to face low rubber prices. Methods in this paper used descriptive analysis with literature studies of the efforts undertaken by rubber smallholder in several rubber producer countries, especially in Thailand, Indonesia, Malaysia, Vietnam, India, and Laos to face low rubber price. This study show that the alternative effort undertaken by rubber smallholder to face low rubber price generally was 1) management of cost production by reduced fertilizer and others factor production which no disturbed rubber income; 2) develop other crops by intercropping technique on rubber interrow; 3) looking for side jobs such as construction laborers, public transportation drivers, opening stalls and catching fish; 4) take of loans to maintain the standard of household living; 5) implement a joint marketing system to obtain a better rubber price; 6 continue to tapping as usual and trying to access the government assistance programs that were oriented towards the sustainability of rubber agribusiness; 7) selling or renting out some of the old rubber land that is no longer productive; 8) carry out new plantings with or without government assistance. The alternative strategy that is considered the most relevant in dealing with low rubber prices and supporting the sustainability of natural rubber agribusiness at this time is the intercropping strategy
