Abstract

Among consumed-vegetable oils, RBDPO (refined, bleached and deodorized palm oil) is indicated containing higher level of 3-MCPDE and GE, which have been classified as potentially carcinogenic and/or genotoxic to human. Those contaminants in RBDPO are formed during deodorization process with high temperature and also correlate with chloride content and quality of CPO as raw material.  The maximum limit for 3-MCPDE and GE content in vegetable oil has been set at 2500 and 1000 µg kg-1, and as low as 750 and 500 µg kg-1 when used for production of baby food and cereal-based foods for infants and young children. The mitigation of 3-MCPDE and GE in RBDPO is quite challenging for palm oil refineries in producing a good quality of palm oil in term of sensory, stability, safety, and nutritional value, especially in Indonesia.  It has been proven that modification of conventional refining process can reduce the 3-MCPDE and GE content. They are including pre-treatment of CPO by water washing to reduce the chloride content, alkali neutralization to remove any acids present in the oil prior to deodorization, using neutral bleaching earth, adding antioxidants after bleaching to reduce free radical-mediated formation of 3-MCPDE and GE, lowering the deodorization temperature with a longer time, and even double bleaching and/or double deodorization of the palm oil.  Post-refining treatment using specific adsorbents is also applied to remove the 3-MCPDE  and GE. However, palm oil  refineries  have  to  apply combination of several mitigation strategies to adequately reduce the levels of 3-MCPDE and GE, including using good quality of CPO with low FFA, chloride, and oxidized components content.

Abstract

Kenaikan harga dan keterbatasan ketersediaan pupuk kimia dalam beberapa tahun terakhir, sebagian disebabkan oleh konflik Rusia–Ukraina, telah meningkatkan biaya produksi pertanian di Indonesia. Pupuk bersubsidi hanya dapat diakses oleh anggota kelompok tani aktif dengan jumlah terbatas, sehingga terjadi ketimpangan akses dan kelangkaan pasokan. Pupuk organik menjadi alternatif yang dapat mengurangi penggunaan pupuk kimia hingga 30% tanpa sepenuhnya menggantikannya. Namun, sebagian besar petani belum memiliki pengetahuan dan keterampilan teknis untuk memproduksinya secara mandiri, meskipun bahan baku lokal seperti limbah tanaman tersedia melimpah di pedesaan. Program pengabdian ini dilaksanakan pada Kelompok Tani Pematang Tobat di Kabupaten Batu Bara, Sumatera Utara—sentra produksi kelapa sawit—dengan tujuan mengenalkan, melatih, dan mendampingi petani dalam pembuatan pupuk organik berbasis limbah kelapa sawit, yaitu tandan kosong kelapa sawit (TKKS) dan solid decanter. Tahapan kegiatan meliputi identifikasi masalah dan sosialisasi, penyerahan mesin pencacah, pelatihan teknis pengomposan sesuai SOP, serta monitoring selama empat minggu. Hasil pelatihan menghasilkan dua tumpukan kompos: cacahan TKKS dan solid decanter yang diberi aktivator mikroba. Hasil monitoring menunjukkan bahwa pengomposan solid decanter berhasil, sedangkan TKKS belum terurai sempurna akibat kondisi panas dan kering berkepanjangan yang menurunkan aktivitas mikroba. Temuan ini menegaskan pentingnya pengendalian suhu dan kelembapan pada proses pengomposan. Program ini membuktikan bahwa dengan pelatihan, pendampingan, dan sarana yang memadai, petani dapat memenuhi sebagian kebutuhan pupuknya secara mandiri, mengurangi ketergantungan pada pupuk kimia, serta menekan biaya produksi.

Abstract

Processing palm fruit produces crude palm oil. Crude palm oil levels continue to increase during the fruit ripening process. The parameters used in determining the maturity criteria for palm oil harvest are color change and fruit breaking off from the bunch. Harvest quality is determined by the mature fraction. One of the problems that occurs in palm oil factories is the selection of palm fruit bunches (FFB), which are divided into three classes, namely unripe, ripe and over ripe. Selection of FFB is done manually, namely visually. The quality of palm oil is greatly influenced by the level of ripeness of the fruit at the time of harvest and post-harvest handling until the mill. This research aims to evaluate the use of variations in palm fruit maturity used in PKS which are related to yield and quality as well as oxidative stability and color. The research results showed that the variation in palm fruit maturity used resulted in the highest yield, namely 17% in P2. The quality of crude palm oil obtained from variations in fruit maturity shows different results, where the highest free fatty acid content of 2.57% is located in P2, namely a mixture of ripe and overripe fruit, while the highest water content is found in P2, namely 0.65 %. P3 has the highest impurity content of 0.68%. The oxidative stability and color obtained from using variations in fruit maturity that were heated for 24 hours decreased in value to red and yellow
