Abstract

The extreme weather condition El Nino can cause Indonesia to experience a prolonged dry season, while La Nina causes a prolonged rainy season. These conditions affect the availability of water in oil palm plantations and affect the physiological processes of oil palm. This research aims to compare the NDVI index and SAVI index using Landsat 8 satellite imagery in the oil palm plantations of PT. Wanapotensi Guna during El Nino and La Nina. Landsat 8 satellite imagery recorded in August 2019 describes El Nino conditions and recorded in August 2020 describes La Niña conditions in the study area were downloaded from the USGS website. The NDVI and SAVI indices were analyzed using ArcGIS 10.5 software. The research results show the value of the NDVI index and SAVI index in the oil palm plantation area of ​​PT. Wanapotesi Guna has a value that is not much different in El Nino and La Nina conditions. The NDVI index value in El Nino conditions has a range of 0.07-0.46 and in La Nina conditions has a range of 0.13-0.44. Likewise, the SAVI index value in El Nino conditions has a range of 0.11-0.70 and in La Nina conditions has a range of 0.20-0.69. So it can be concluded that the NDVI index and SAVI index obtained from Landsat 8 satellite imagery cannot describe significant differences in index values ​​in oil palm plantation areas due to differences in the extreme weather conditions of El Nino and La Nina.

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.

Abstract

Oil palm canopy is formed every month as many as 1-3 fruits, depending on the age and growth of the plant. Each oil palm canopy supports the formation of leaf/frond positions that are arranged in a spiral. Progressive pruning of the main shoots is carried out directly by harvest workers (not the Special Main Shoot Work Team) and is carried out simultaneously when cutting the fruit while still referring to the basic principle of the number of productive fronds that must still be maintained according to the provisions (leaf area index). This study aims to determine the role of the progressive pruning system in minimizing looses (bunches and looses fruit) in oil palm plantations. The basic method used in this study is a quantitative descriptive method using t-test analysis, the parameters used are the looses of bunches and looses fruit. The conclusion of the study is that the progressive pruning system can reduce losses of oil palm fruit (bunches) and loose fruit, compared to the periodic pruning system at the overall looses point of the three looses point chains, namely at the main, plate and market.

Abstract

Cendawan mikoriza arbuskula (CMA) mempunyai beragam peran dalam banyak agroekosistem, termasuk perkebunan kelapa sawit. CMA menjadi bagian strategis dalam budidaya kelapa sawit secara berkelanjutan, termasuk perkebunan rakyat. Penelitian ini bertujuan untuk mengungkap diversitas dan populasi CMA dalam hubungan dengan sifat tanah perkebunan rakyat. Sampel tanah komposit diambil dari zona perakaran kelapa sawit sedalam 5-20 cm pada 6 lokasi perkebunan rakyat yang berbeda. Isolasi dan kerapatan spora CMA ditentukan dengan metode tuang saring dilanjutkan dengan identifikasi genus dan observasi kolonisasi kelapa sawit. Sifat tanah diamati untuk menentukan status hara, kandungan bahan organik, pH dan KPK. Hasil penelitian menunjukkan diversitas CMA di perkebunan rakyat rendah, hanya ditemukan 3 genus dengan kerapatan yang berbeda. Acaulospora sp. ditemukan pada semua kebun dengan kerapatan tertinggi dan Glomus sp. dengan kerapatan rendah, sedangkan Gigaspora sp. jarang ditemukan. Spora Acaulospora sp. dan Glomus sp. melimpah pada tanah masam dengan kandungan bahan organik rendah. Spora CMA tidak ditemukan pada tanah yang mempunyai pH netral dan kandungan bahan organik, P total dan tersedia, Fe dan Zn yang tinggi dan sering kalitergenang (kebun Sungai Kupang). Acaulospora sp. dan Glomus sp. berpotensi besar menjadi pupuk hayati untuk perkebunan kelapa sawit rakyat, terutama pada tanah yang kurang subur.Kata kunci : sifat tanah, perkebunan sawit rakyat, diversitas, FMA

Abstract

Eleusine indica is a grass weed in oil palm plantations, especially during the period of immature crops. The application of glyphosate for weed control shows diverse effectiveness. This study aims to determine the age of susceptible weeds in increasing the effectiveness of glyphosate in controlling E. indica. The study tested the application of glyphosate with three levels (486, 729, and 972 g/ha) at three different weed ages (3, 6, and 9 weeks). E. indica was taken from oil palm plantations that were previously glyphosate-depleted, then sprayed with glyphosate according to the dose studied. Each treatment combination is represented by five pots containing five individual weeds. The results showed that the application of glyphosate aged three and six weeks of higher effectiveness controlled E. indica for doses of 486 and 729 g/ha) than a nine-week application for all doses tested. Regrowth of weeds is found mainly the application of glyphosate at the age of a month of weeks. The development of E. indica's resistance to glyphosate needs attention in oil palm plantations.
