“…Indonesia is quite complex, which can lead to low productivity. Palm oil nursery is the first step that can support the success of the plantation (Sartini et al, 2018). The other determining factors in seed processing are influenced by the planting medium used.…”

Palm oil can produce high productivity which must be supported from several aspects, one of them is a good and correct nursery. Palm oil nursery isusually carried out conventionally, namely planting using soil media. Hydroponic research using cocopeat and rice husks planting media on the growth of palm oil seeds in pre nursery has never been carried out. The objective of this study was to determine the growth of palm oil seedlings using the hydroponic method. This research was conducted in the STIPAP Medan greenhouse. This research was conducted from April to July 2018. This research was a non-factorial RAK, which consisted of four treatments, namely M0 (top soil), M1 (Cocopeat), M2 (rice husks), M3 (combination). Height, stem, number of leaves, dry and wet weight of roots and plants, root length were observed. Then data analysis with ANOVA with the continued test of 5% Duncan was performed. The results of the effect of cocopeat and rice husk media was there was no a significant effect on the treatment parameters of seed height, number of leaves, dry and wet weight of roots and plants, and root length.

The aim of the research is to find out the comparison level of production, production costs, reception and the income on the agricultural of palm oil prenuership and to analyze the level of economic efficiency. This research is conducted with a purposive sampling method. The research is showing result that the production is using the juice of Juhar is 70.792 kg. With the use of NPK there are 604 kg. But from the data above can be found that the production of the palm oil is higher using the Juhar fertilizer than NPK fertilizer. The cultivation of the palm oil which useing Juhar fertilizer is better than using the NPK fertilizer.

“…Selanjutnya, proses hidrolisis menggunakan larutan H2SO4 dan difermentasi menggunakan ragi saccharomyces cerevisiae. Kadar etanol tertinggi pada penambahan larutan H2SO4 20 mL dengan fermentasi selama 6 hari, yaitu diperoleh kadar bioetanol tertinggi dihasilkan sebesar 7.12% (Pratiwi et al, 2013), sedangkan pada perlakuan penambahan larutan H2SO4 2% dan fermentasi selama 2 hari diperoleh kadar etanol sebesar 4.94% (Sartini et al, 2018). Berdasarkan penelitian tersebut, kadar etanol yang dihasilkan masih kurang optimal, sehingga diperlukan penelitian lebih lanjut seperti pengembangan proses dalam pembuatan bioetanol generasi kedua.…”

Tandan kosong kelapa sawit (TKKS) yang merupakan sumber gula mengandung selulosa yang tinggi (75-80%), sehingga memiliki potensi besar untuk dijadikan bioetanol. Tujuan penelitian adalah menggunakan kembali tandan kosong kelapa sawit sebagai bahan utama dalam pembuatan bioetanol generasi II dengan melakukan pengembangan proses. Proses pertama yaitu pretreatment dengan menambahkan NaOH dan H2SO4 2%, dilanjutkan proses fermentasi menggunakan perbandingan Saccharomyces cerevisiae and Aspergillus oryzae dengan perbandingan 5,10,15 dan 20% selama 7 hari. Terakhir adalah proses destilasi pada suhu 79 oC. Berdasarkan hasil penelitian, larutan NaOH lebih banyak menurunkan kadar lignin dan hemiselulosa sebesar 12.22% dan 45.17%, sedangkan selulosa mengalami kenaikan sebesar 71.34%. pada proses fermentasi, maka didapatkan variasi konsentrasi dan waktu optimum proses fermentasi pada penelitian ini adalah penambahan konsentrasi Saccharomyces cerevisiae 5%, dengan volume bioetanol yang dihasilkan sebesar 14.4 ml, densitas 0.8757 g/ml dan kadar glukosa yang tertinggal sebanyak 8.48%.
