Decanter is used to separate oil phase from underflow sludge of continuous settling tank (CST) in Palm Oil Mills (POM). The most commonly type of decanter is 3-phase decanter. This paper describes the brand preferences in 3-phase decanter selection by using the Analytical Hierarchy Process (AHP) method. Before the AHP was done, expert correspondent prepared a list of criteria and sub-criteria for 3-phase decanter brand selection. AHP was conducted in 3 steps, which were: i) criteria classification, ii) pair-wise comparison of criteria and sub-criteria, that did by user correspondent, and iii) evaluation on the 3-phase decanter selection based on the brand comparison, that did by user correspondent. AHP simulation was carried out using Expertchoice® version 11. The first step of AHP generated: i) a question list arranged in questionnaire form, regarding criteria and sub-criteria concerning the brand of the decanter, and ii) weight value for each question. The second step of AHP revealed that technical criteria are preferable to economic than technical criteria. The spare part availability has the highest preference value amongst the economic sub-criteria, while oil losses has the highest preference in the technical sub-criteria. The third step of AHP showed that the decanter of Brand B is on the top ranking, with an economic and a technical preference value of 0.148 and 0.130, respectively. These results indicated that preference values can change if a complex analysis of criteria, sub-criteria, and decanter brands is involved in the one system analysis. Results of sensitivity analysis shows that both the decanter of Brand B and Brand E get the first rank in preference, which Brand E is on third rank before the sensitivity analysis is deducted.

The conventional soil management practices employed in oil palm plantations often overlook the critical aspect of soil biology, leading to potential detrimental effects on soil health and fertility, primarily driven by the excessive utilization of inorganic fertilizers. However, there is growing evidence that biofertilizers, comprising beneficial bacterial consortia, hold significant promise as an alternative approach for sustainable agriculture while mitigating environmental impacts. Extensive research has been conducted to explore the application of biofertilizers and investigate their impact on the growth and yield of oil palm. In a study conducted on a demo plot of oil palms planted in 2008 in South Sumatra since 2019, a randomized complete block design with five treatments was implemented. The application of biofertilizers yielded notable outcomes, including a substantial increase in the bacterial population, surpassing the threshold of 108 cfu.g-1. This upsurge in bacterial populations signifies a positive shift towards enhanced soil microbial activity and functioning. Furthermore, the application of biofertilizers demonstrated significant improvements in crucial growth parameters. Leaf area exhibited an increase ranging from 8.5% to 17.2%, while dry frond biomass showed a remarkable boost ranging from 8.6% to 14.9%, in comparison to the usage of 100% inorganic fertilizers. Moreover, the combination of inorganic fertilizers with biofertilizers (S75B1, S75B2, S50B1, and S50B2) exhibited enhanced fertilizer efficiency and ultimately resulted in higher oil palm yields compared to the usage of 100% inorganic fertilizers. This valuable finding underscores the potential of integrating biofertilizers into conventional fertilization practices to achieve optimal agricultural productivity while minimizing environmental impact.

Superior seeds are critical in increasing oil palm productivity in Indonesia, especially for smallholder farmers. Producers who produce oil palm planting materials play a vital role in providing quality seeds whose purity can be guaranteed (legitimized). The Indonesian Oil Palm Research Institute (IOPRI) is the only state-owned palm oil seed producer. The superior varieties of IOPRI, which are produced to increase palm oil production, will impact consumer behavior in selecting palm oil seeds. This research analyzes consumer attitudes, preferences, and satisfaction regarding using superior varieties of IOPRI germinated oil palm seeds. The data used in this research is primary data, with a total sample of 44 farmers. The analytical methods used are the Fishbein, Konjoin, Importance, and Performance Analysis (IPA) methods and the Customer Satisfaction Index (CSI). The research results show consumer attitudes towards the overall attributes of PPKS superior seed using the Fishbein method are in the very like category with a score of 24.04. Meanwhile, the preferences of farmers using conjoint analysis are very favorable, namely for Fresh Fruit Bunches (FFB) production potential of 38 tonnes/ha/year, high growth rate of 62.5 – 65 cm/year, tolerance to Ganoderma sp., planting density of 130 trees/ha, cardboard packaging, purchase by coming in person, 10% discount, and price Rp. 8000. IPA analysis shows that the suitability of varieties with planting density and the suitability of varieties with land type are included in quadrant I, so these two attributes do not satisfy farmers and are the main priority in making improvements. Meanwhile, consumer satisfaction with all attributes of the superior IOPRI variety shows a CSI value of 81%. The result shows that the farmer satisfaction index for IOPRI germinated oil palms seeds is very satisfied.

The area of oil palm plantations in Indonesia is increasing from 14.0 million ha in 2017 to 16.8 million ha in 2022, which implies an increase in the need for harvesting and maintenance labour. Currently, in Indonesia, it is increasingly difficult to find trained field labour, especially in harvesting and loading Fresh Fruit Bunches (FFB) in the palm oil industry. In the industrial era 4.0, the use of mechanisation is a potential solution to overcome labour scarcity in the agriculture and plantation sectors. Mechanisation in harvest management involves the use of tools such as: tractor scissor lift grabber, quick tractor, crawller dump, along-along, wintor and truck bin system which functions to evacuate FFB from the collection point (TPH) to delivery to the palm oil mill (PKS). This study aims to evaluate the advantages and disadvantages of the use of mechanisation in the process of transporting production and analyse its financial feasibility through the NPV, IRR, B/C and PP analysis methods. The calculation results showed that the truck bin system obtained an NPV value of Rp 424 million, IRR 21.38%, B/C 1.21, PP 5 years. tractor scissor lift grabber obtained NPV IDR 433 million, IRR 22.5%, B/C 1.28, PP 5 years, quick tractor obtained NPV IDR 39 million, IRR 23.91%, B/C 1.11, PP 3 years, wintor reached NPV IDR 45 million, IRR 26.05%, B/C 1.27, PP 3 years, and Along-along recorded NPV IDR 78 million, IRR 212.1%, B/C 1.49, PP 1 year. The results of this study show that mechanisation is technically and economically feasible in oil palm plantations.

Palm oil plantations are often criticized for poor governance practices covering environmental, social, and economic aspects. Sustainability certification has emerged as a solution to these issues, offering assurances of sustainability in the supply chain to stakeholders, including smallholders. Without certification, smallholders face significant risks, including market volatility and production losses, which able to impact their income and the sustainability of their operations. This study aims to evaluate and compare production and income risks between certified and non-certified smallholders. Research method involves calculating the coefficient of variation to measure risk. Results show that certified smallholders face lower risks compared to non-certified smallholders, both in terms of production and income. This reflects better risk management, particularly in more efficient labor allocation and higher financial gains, despite higher costs. This success is inseparable from the support of the RSPO and cooperatives, which play a vital role in fulfilling the commitment to achieve the goals outlined in the Theory of Change (ToC).
