               INTRODUCTION
               Oil palms are recognized for their exceptional oil yield, the average oil yield per hectare is 3.7 to 4.6 ton of
               palm oil compared to 0.6 tons rapeseed oil and 0.36 tons soya oil [1,2] . Malaysia and Indonesia produce
               approximately 87% of the global palm oil . In contrast to other biomass products, which are mainly
                                                    [3]
               consumed locally in the countries of production, more than half of the produced palm oil is exported .
                                                                                                        [4]
               Crude palm oil production in Indonesia grew from approx. 8 million tons in 2001 to 48 million tons in 2022.
               The expansion of oil palm plantations was associated with the deforestation of approx. 3 million ha over the
               past 20 years . As of 2020 approx. 21% of the cleared forest in Indonesia is utilized for oil palms plantations,
                         [5]
               according to . Palm oil residues are produced throughout the year and thus can be considered as major crop
                         [6]
               residues for power production, particularly in remote rural areas. Given the importance of palm oil for the
               national economy, the Indonesian policy on renewable energy is closely linked to its development,
               particularly to improve living standards and welfare in rural areas. In the long-term, renewable energy
               development, such as biogas from residues of the palm oil industry, may significantly contribute to a
               sustainable national energy supply. The management of residues is a paramount criterion for sustainable
               palm oil . Residue management is also one of the key factors for greenhouse gas (GHG) emission reduction
                      [7]
               of the palm oil industry  and can generate additional income depending on access to the electricity-grid
                                   [8,9]
               and attractive feed-in-tariffs.

               The competition for palm oils between food, feedstock for chemicals, and biodiesel applications has put it in
               the limelight, resulting in a controversial worldwide debate [2,10-12] . By replacing tropical forests, new palm
               plantations provoke the killing of endangered species, uprooting of local communities, and release of huge
               amounts of GHG. Europe has banned biofuel feedstock and biofuels with a high risk of causing indirect
               land-use change in high carbon stock areas, however, with limited effect on deforestation [13,14] , because larger
               markets in China and India as well as the domestic market tend to source palm oil and derived products
               from supply chains with comparatively higher rates of deforestation risk . Zero-deforestation commitments
                                                                           [15]
               are widespread in Indonesia, but that does not ensure the absence of deforestation risk . While contributing
                                                                                       [16]
               to economic growth, the expansion of palm oil production has been a key driver of deforestation in the
               country. Most deforestation linked to palm oil has historically been driven by large-scale producers.
               Smallholders are however increasingly identified as important actors in relation to the deforestation of
               forests and peatlands in Indonesia .
                                           [16]
               Palm oil production is important for the Indonesian economy; it employs over 20 million people , the
                                                                                                     [17]
               majority as plantation workers in rural areas. Plantation enterprises pay attention to economic factors and
               the social welfare of the community and surrounding areas and show concrete signs of improving the welfare
               of the community by strengthening the economy of the community .
                                                                       [18]

               Oil palms are produced by nucleus estate and smallholder managed schemes, sometimes via joint-venture
               schemes but also by independent smallholders . Oil palm cultivation has improved living standards and
                                                       [19]
               alleviated the poverty of many smallholder farmers . However, there is a huge gap between the economic

               performance of professionally managed plantations with sufficient resources to buy seed, fertilizer, and plant
               protection agents compared to the agronomic performance of small holder’s plantations. The average yield
               of Indonesian smallholders is reported at approx. 11 tons fresh fruit bunches (FFB) ha , while private
                                                                                             -1
               company plantations in favorable sites often reach yields of more than 30 tons FFB ha -1[21] . Monzon reported
