Abstract

Indonesia's palm oil industry has long faced criticism and denial, accusations that the palm oil industry is unsustainable, and smallholder plantations are seen as contributing to environmental risks. In response to this, the Indonesian government, to ensure the sustainability of the palm oil industry, created a sustainability standard called ISPO, which is mandated to be mandatory for all companies and smallholders through presidential regulation number 44/2020 with a grace period of 5 years to fulfill these obligations. However, these efforts faced various problems, especially for independent smallholders. Based on the problems faced, this study aims to determine the realization of ISPO principles and criteria and identify the achievement of ISPO principles and criteria in smallholder oil palm plantations in Tungkal Ilir District, Banyuasin Regency. The research method used is a quantitative descriptive approach with Guttman scale measurements to analyze the realization of the application of ISPO principles and criteria and identify the achievements of ISPO principles and criteria. From many study results, the realization of the implementation of ISPO principles and criteria in Tungkal Ilir District from the available indicators has yet to be met, and many still need to.  Many require more attention, including the criteria for legality and management of smallholders, criteria for obligations related to environmental permits, technical criteria for applying oil palm cultivation and transportation, and the principle of implementing transparency.

Abstract

Cocoa is one of the commodities as a foreign exchange earner in addition to oil and gas. However, Indonesian cocoa imports have increased from year to year due to low cocoa productivity. Whereas in terms of region, Indonesia has the potential to become a new cocoa power country in the world of cocoa production. This study examines the effect of rainfall, the number of rainy days, and air temperature on cocoa production in the Gunungkidul district. This study uses a quantitative descriptive method. The data used in this study is secondary data in the form of time series data on rainfall, rainy days, air temperature, and cocoa production in 2016-2020 in Gunungkidul Regency. The regression analysis results showed that all observed climatic factors such as rainfall, rainy days, and temperature did not have a significant effect on cocoa production in Gunungkidul Regency. However, the time-series data shows that the highest cocoa production was in October 2017 and November 2018 to January 2019, when rainfall and intensity (rainy days) began to increase. Meanwhile, the air temperature in Gunungkidul Regency for five years is around 24-26°C, which is the optimum temperature for cocoa growth. This study concludes that rainfall, rain intensity (rainy days), and temperature affect fluctuations in cocoa production.

Abstract

The oil palm yield depends on its genetic and the interaction with environmental factors is affected by spatial arrangement of palm trees. The research objectives are to determine the effect of population density and planting year on oil palm productivity and vegetative growth. This research uses a factorial design arranged with a randomized complete design. Secondary data are palm productivity, fresh bunch number and bunch weight that were collected for three years (2019—2022). Primary data are stem height, frond length, and stem gird which were measured on 90 trees for each treatment combination. There are nine combinations with 810 palm trees that were sampled from 27 estate blocks (30 hectares for one block). The results showed that productivity and amount of oil palm FFB at densities ≥ 142, 136-141, and ≤ 135 SPH and planting years 2007, 2009 and 2011 (mature crop 12-15, 10-13, and 8-11 years) did not show significant differences. The heavier bunch weight was produced palm tree planted in 2007 with density ± 135 trees.ha-1.

Abstract

Basal stem rot caused by the fungus Ganoderma boninense is the major threat to oil palm plantations in Indonesia, especially for second generation. Handling oil palm residues during the replanting process greatly determines the fungal attack. This research aims to reveal how handling oil palm trunks affects G. boninense attacks on second generation oil palm plantations. The treatments studied were felled trunk and felled-chipped trunk, each represented by two blocks (five years old of oil palm) with a density of 143 trees/hectare. The results of the study showed that second generation oil palms had a very high prevalence of basal stem rot disease, even though there were differences in the incidence and severity of the disease. Chipping of felled trunk residues can slow the development of the disease. Management of palm residues has a major influence on the onset of this disease in replanted oil palms.
