“…The correlation between fatty acids and carotene are also similar to report by Montoya et al (2013) and Siregar, Rahmadi, Wening, & Suprianto (2018). Negative correlation between oleic to palmitic and myristic are very significant but are not any significant to total carotene (Table 4).…”

“…The profile of fatty acids of virescens type was dominated by palmitic, linoleic, stearic and oleic with total ranging from 97.78-98.91%. It is similar to profile of fatty acids of E. oleifera population (Montoya et al, 2013;Siregar, Rahmadi, Wening, & Suprianto, 2018) and Elaeis guineensis nigrescen (Montoya et al, 2014), then followed by lauric, myristic, palmitoleic, linolenic, arachidic and gadoleic, with total ranging only from 1.09-2.22%.…”

In the assumption of oil palm breeders, virescens oil palm type has no real economic value. Therefore, the nigrescens is more considered. However, the virescens gives a visual cue that fruits are ripe without waiting to detach. In 2010, Indonesian Oil Palm Research Institute (IOPRI) successfully planted an open-pollinated population of Cameroon oil palm. The population was characterized for virescens type frequency, as well as the bunch components, quantity and quality of crude palm oil. The virescens frequency per accession was sufficiently wide, ranging from 3.33-65.71%, and was affected by the parent type, nigrescens or virescens. Most of the virescens's fruit form is observed to be of dura, except one sample, which was observed to be tenera. The mesocarp to fruit (MF) and industrial extraction ratio (IER) percentage are similar to the nigrescens dura, namely 37.7% and 9.5%, respectively. Its oil quality is better than nigrescens, and it has total carotene ranging from 155-1246 ppm. The oleic fatty acid is higher than 50%, and the palmitic is lower than 40%. Due to the ease of determining mature fruits, as well as the higher oil quality, virescens oil palm type is recommended to be introgressed in a breeding program.

“…Menurut Siregar et al (2006), cekaman kekeringan pada tanaman kelapa sawit akan terjadi apabila terdapat salah satu dari parameter-parameter ini terpenuhi: curah hujan (CH) kurang dari 1250 mm/tahun, defisit air di lahan lebih dari 200 mm/tahun, terjadi bulan kering lebih dari 3 bulan, serta deret hari terpanjang tidak hujan (dry spell) lebih dari 20 hari. Berdasarkan pengamatan lapangan, diketahui bahwa sebagian besar tanaman kelapa sawit mengalami cekaman kekeringan.…”

“…Untuk mengurangi dampak cekaman kekeringan, perlu dilakukan langkah teknis pasca kekeringan antara lain melalui aplikasi pemupukan tepat waktu segera setelah kekeringan berakhir yaitu apabila curah hujan > 150 mm/bulan atau telah turun hujan 50 mm/10 hari (Siregar et al, 2006), pelaksanaan pemupukan pada Semester I (SM-I) tahun setelah kekeringan dilaksanakan lebih awal (Februari -Maret) dengan proporsi pupuk 65% di SM-I dan 35% di SM-II, aplikasi bahan organik (Freidrich, 2011), pengendalian gulma tidak secara blanket untuk menjaga kelembaban tanah (Lubis, 2008), serta pembuatan bangunan konservasi tanah dan air seperti rorak, embung, maupun guludan (Murtilaksono et al, 2011).…”

Abstrak El Niño 2015 merupakan salah satu El Niño terkuat. Cekaman kekeringan yang disebabkan oleh El Niño 2015 akan mempengaruhi performa tanaman kelapa sawit. Penelitian ini dilakukan untuk mengetahui pola curah hujan serta performa kelapa sawit selama El Niño 2015 khususnya di Pulau Sumatera dan Kalimantan. Data yang digunakan dalam penelitian ini adalah data curah hujan Januari-Desember 2015, data Southern Oscillation Index (SOI) bulanan, dan performa tanaman kelapa sawit. Analisis pola curah hujan dilakukan dengan analisis korelasi Pearson (r) antara SOI dan curah hujan, sedangkan performa tanaman diamati berdasarkan kondisi morfologis tanaman. Hasil kajian menunjukkan bahwa wilayah Sumatera Bagian Selatan serta sebagian besar Kalimantan mengalami deret hari kering, bulan kering dan defisit air yang lebih tinggi berturut-turut yaitu 37-133 hari, 3-5 bulan, dan 349-524 mm. Hasil analisis pola curah hujan menunjukkan bahwa Jambi, secara signifikan dipengaruhi oleh kejadian El Niño 2015, dengan r ≥ +0,60. Tanaman kelapa sawit yang berada di Sumatera bagian selatan serta sebagian besar Kalimantan mengalami cekaman kekeringan ditandai munculnya lebih dari dua daun tombak, banyak muncul bunga jantan, malformasi tandan, pelepah sengkleh, dan pelepah lingkar terbawah mengering. Kata kunci : kelapa sawit, El Niño, kekeringanAbstract El Niño 2015 is one of the strongest El Niño. Drought stress due to El Niño could affect oil palm performances. This study was conducted to determine rainfall pattern and oil palm performance in Sumatra and Borneo Island during El Niño 2015. Data employed in this study is monthly rainfall data, Southern Oscillation Index (SOI) January-December 2015, and oil palm performances. Pearson correlation between SOI and rainfall data was used to analyze rainfall pattern, while oil palm performances were observed based on morphological conditions. Result shows that southern part of Sumatra and mostly part of Borneo suffer from more dry spell, dry month, and water deficit such as 37-133 days, 3-5 months, and 349-524 mm respectively. Analysis of rainfall pattern shows that Jambi, South Sumatra, Lampung, Central, South, and East Borneo are significantly (r ≥ +0,60) affected by El Niño 2015. Oil palms in southern part of Sumatra and mostly part of Borneo are suffer from drought stress marked by the emergence of more than two spear fronds, appearing of many male flowers, malformations on bunches, fronds tend to hanging down, and lower fronds tend to dry.

“…Sitoresmi [10], has reported the addition of fatty acid by 7.5% can reduce the number of protozoa by 23.95% and reduce the amount of methane gas production by 18.51%. Ten types of fatty acids from CPO crude palm oil were observed such as laurate (C8), myristate (C14), palmitate (C16), palmitoleate (C16: 1), stearate (C18), oleate (C18: 1), linoleate (C18: 2), linolenic (C18: 2), arachidate (C20: 4), and gadoleate (C14: 0) [11]. Single fatty acid was reported to have a particularly high potential in suppressing ruminal methanogenesis [12].…”

Objective: The purpose of this research was to evaluate the effect supplementation of mimosa powder as a source of condensed tannins and a single fatty acid, myristic acid, in a complete feed based on corn stover (Zea mays) using the in-vitro gas production method. This research has been carried out at the Animal Nutrition and Food Laboratory, Faculty of Animal Husbandry, Brawijaya University. The time of the research was conducted in August until December 2019.Methods: The experimental design used randomized complete block design by ANOVA consisting four treatments and three replications which were P1= a complete feed based on corn stover (Zea mays) as control Diet (CD) (40% corn stover + 60 % concentrate), P2= (CD) + Mimosa Powder(MP) 1.5 %/kg DM + myristic acid (MA)2% /kg DM, P3= CD + MP 1.5 % /kg DM + MA 3% /kg DM, and P4= CD + MP 1.5 %/kg DM + MA 4 %/kg DM.Results: The results showed that the treatments affected total gas production (p<0.01). The highest value for total gas production was found in P1 (86.67 ml/500 mg DM) and the lowest was found in P3 (73.30 ml/500 mg DM). The results showed that gas production decreased concurrently with the increase of MA level. In vitro methane gas and carbon dioxide production was showed different (p<0.05) from the control treatment. The lowest concentration of methane production was in P4 (82863.07 ppm) and the highest concentration was in treatment P1 86530.89 ppm. The highest total carbon dioxide content was P1 (436711.57 ppm) and the lowest concentration was P3 (350287.72 ppm).Conclusions: The results of the research concluded that the addition of mimosa powder and 3 different levels of myristic acid in a complete feed based on corn stover can increase the nutritional value of a complete feed and reduce the production of methane gas.
