Exploration of palm fronds as a prominent alternative resource for the production of energetic cellulose-rich biopolymers

In this research, the challenges of using human capital and the effectiveness of social capital as an alternative resource used by immigrant women from non-English-speaking countries living in Central Alberta for them to attain economic security are studied. Evidence indicates heavy use of bonding social capital by immigrant women—primarily through family, ethnic, and religious networks—as a “survival” resource at the initial stage of settlement. The bonding social capital is relatively easy to access; nevertheless, in the case of visible minority immigrant women living in Central Alberta, bonding social capital has limited capacity in helping them to obtain economic security because their family and friends themselves often lack economic resources. As a result, these immigrant women are expected to compete in the labor market using their human capital to obtain higher-paying jobs. The challenge among immigrant women remains in seeking recognition of non-Canadian credentials, and/or successful acquisition and deployment of Canadian credentials in the primary labor market.

ABSTRACTThe growth response of oil palm (Elaeis Guineensis Jacq.) seedling toward the application of organic fertilizer from palm fronds and NPK compound fertilizerThe research was aimed to study the influence between organic fertilizers from palm fronds and NPK compound fertilizer to reduce NPK compound fertilizer in main nursery. The experiment was conducted from January to April 2017 at the Experiment Station Ciparanje, Faculty of Agriculture, Universitas Padjadjaran. The experimental design used was Randomized Block Design that arranged in factorial patterns with two factors and three replications. The fisrt factor was dosage of organic fertilizers from palm fronds consisted of three levels of 0 g/polybag, 800 g/polybag, and 1600 g/polybag and the second factor was dosage of NPK compound fertilizer consisted of four levels of 0 g/polybag, 20 g/polybag, 40 g/polybag, and 60 g/polybag. The result of the experiment showed that there was interaction effect between organic fertilizers from palm fronds and NPK compound fertilizer on height of seedling and dry weight of the shoot. The dosage of 1600 g/polybag organic fertilizers from palm fronds with the dosage of 20 g/polybag NPK compound fertilizer showed the best result in dry weight of the shoot.Keywords: Oil palm seedling, Main nursery, Organic fertilizer, Palm frond, NPK compound fertilizerABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh interaksi antara pupuk organik asal pelepah kelapa sawit dengan pupuk majemuk NPK yang baik untuk mengurangi penggunaan pupuk majemuk NPK di pembibitan utama kelapa sawit. Percobaan dilaksanakan dari bulan Januari sampai dengan April 2017 di Kebun Percobaan Ciparanje, Fakultas , Universitas Padjadjaran. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok dengan pola faktorial yang diulang sebanyak tiga kali. Faktor pertama meliputi dosis pupuk organik asal pelepah kelapa sawit terdiri dari tiga taraf yaitu 0 g/polybag, 800 g/polybag, dan 1600 g/polybag dan faktor kedua dosis pupuk majemuk NPK yang terdiri empat taraf yaitu 0 g/polybag, 20 g/polybag, 40 g/polybag, dan 60 g/polybag. Hasil percobaan menunjukkan bahwa terdapat pengaruh interaksi pupuk organik asal pelepah kelapa sawit dengan pupuk majemuk NPK terhadap tinggi tanaman dan bobot kering tajuk. Perlakuan pupuk organik asal pelepah kelapa sawit 1600 g/bibit dengan pupuk majemuk NPK 20 g/bibit menghasilkan bobot kering tajuk bibit kelapa sawit terbaik.Kata Kunci: Bibit kelapa sawit, Pembibitan utama, Pupuk organik, Pelepah kelapa sawit, NPK

Palm Frond

This study investigates the influence of blade lifting angles, tractor forward speed, and tractor power take off (PTO) speed on the degree of mulching. Four blades with different lifting angles, two tractor PTO speeds, and three tractor forward speeds were assessed using the parametric test at the Universiti Putra Malaysia oil palm plantation. The result shows that the best-fit regression equation was a quadratic regression with a high coefficient of determination. It indicates that any change in this three-factor interaction has a significant effect using Tukey’s Studentized mean comparison and can predict the degree of mulching. Seventy-four percent of the degree of mulching variance is explained by blade lifting angles, tractor forward speed, and tractor PTO speed. Since the blade lifting angle was a major predictor of the degree of mulching, this result implies that any change in the blade lifting angle can provide a significant prediction of the degree of mulching in an oil palm plantation. Additionally, the predicted model can further be used to predict the degree of mulching during field operations, replanting, and access for mulching of oil palm fronds. A detailed field evaluation of the performance of a tractor-mounted mulcher with different blade lifting angles in other parts of Malaysia is highly recommended to cater for the differences in soil moisture content and bulk density.
