Fertilizer efficiency is a ratio between the amount of nutrient that absorbed by the plant and the amount of nutrient that applied through fertilizer. The efficiency of a fertilizer can be defined as the number of nutrients that can be absorbed by the plan. The objective of this study was to compare the efficiency of three types of fertilizers on the oil palm seedling. This research was conducted on Indonesian Oil Palm Research Institute at Medan, North Sumatra, Indonesia. Four treatments with three replications were arranged by a completely randomized design. The treatments are: 1) P0 = control/no fertilizer; 2) P1 = Briquette compound fertilizer, 3) P2 = Granular compound fertilizer, and 4) P3 = single-nutrient fertilizer; Urea, TSP, MoP, and Kieserite. The results showed that (I) nutrients uptake (NU) of N, P, K, and Mg on briquette compound fertilizer relatively higher about 11%; 21%; 9%; and 23% compare to granular compound fertilizer and 5%; 1%; 1% and 19% higher than P3 respectively; (ii) recovery efficiency (RE) of N, P, K, and Mg on briquette compound fertilizer were 18%; 42%; 16%; and 20% higher than granular compound fertilizer and 8%; 1%; 2%; and 19% than single-nutrient fertilizer; while (iii) agronomic efficiency (AE) of N, P, K, and Mg on Briquette compound fertilizer were higher about 26% (for each nutrient) compare to Granular compound fertilizer and 18% higher (for each nutrient) than single-nutrient fertilizer.

Tiga ratus sembilan puluh limasampel pohon terdiri dari populasi liar Elaeis oleifera origin Brazil dan Suriname, turunan hibridanya dengan Elaeis guineensis, dan silang balik semu pertama berhasil diamati untuk karakter asam lemak dan total karoten menggunakan gaschromatographydan UV spectrophotometry. Pengamatan dilakukan terhadap lebih dari 648 buah tandan dalam selang waktu 17 bulan. Karakter komposisi asam lemak dan total karoten memiliki keragaman yang lebih luas dibanding varietas komersial di Indonesia saat ini. Populasi pseudo-backcrosspertama baik dari E. oleifera originBrazil maupun Suriname lebih berpotensi diintrogresikan ke dalam program pemuliaan saat ini dibanding populasi liar dan hibridanya disebabkan pertumbuhan batang yang sudah mewarisi sifat E. guineensis. Berhasil ditemukan pada populasi pseudo-backcrosspertama beberapa individu dengan kandungan asam lemak tak jenuh oleat dengan nilai >50% dan kandungan karoten ³2000 ppm. Analisis korelasi antar asam lemak juga dipaparkan dalam tulisan ini yang menunjukkan hubungan yang sedikit berbeda antara populasi hibrida dan pseudo-backcrosspertama, dan bila dibandingkan dengan populasi E. guineensis. Diperlukan penelitian lebih lanjut seperti teknik kultur jaringan dan association studies untuk percepatan penggunaan material turunan E. oleifera.

Minyak sawit merah (MSM) merupakan produk olahan minyak sawit mentah (crude palm oil, CPO) yang masih mengandung karoten (sebagai provitamin A) dalam jumlah tinggi. Sayangnya, MSM belum diminati oleh masyarakat di Indonesia karena warnanya kemerahan dan berbau khas. Penelitian ini dilakukan untuk meningkatkan kesukaan MSM dengan penambahan minyak nabati beraroma cukup kuat seperti minyak inti sawit, minyak kelapa dan lemak cokelat sebanyak 10 - 30 % atau flavor butter sebanyak 0,05 - 3%. Selain itu, dilakukan uji stabilitas MSM, campuran MSM:minyak kelapa dan MSM:flavor dalam penggorengan kentang secara deep frying sebanyak 10 kali penggorengan. Pencampuran MSM dengan minyak nabati atau flavor dapat merubah karakteristik, meningkatkan mutu, dan kesukaan panelis. Semakin tinggi konsentrasi minyak nabati atau flavor cenderung meningkatkan kesukaan panelis terhadap aroma. Minyak kelapa merupakan minyak yang memiliki tingkat kesukaan tertinggi. Penggunaan flavor yang yang masih dapat diterima dari penampakannya adalah sebanyak 0,5%. Campuran MSM:minyak kelapa (80:20) dan MSM dengan flavor 0,5% memiliki kestabilan mutu tinggi selama penggorengan berulang dan tingkat kesukaannya terhadap produk gorengannya juga meningkat dibandingkan MSM.

Abstrak Media tumbuh merupakan faktor penting dalam menunjang pertumbuhan bibit kelapa sawit. Ketersediaan unsur hara dan air dalam media tanam perlu mendapat perhatian utama kaitannya dengan penyediaan media tanam bagi bibit kelapa sawit. Ketersediaan air yang baik dalam media tanam dapat diupayakan dengan penambahan pupuk organik di mana langkah ini diharapkan meningkatkan daya pegang tanah terhadap air dalam media tanam. Tujuan penelitian ini adalah untuk mengkaji komposisi media tanam dan interval penyiraman. Waktu pelaksanaan percobaan dari bulan April 2017 sampai Agustus 2017 di Kebun Percobaan Ciparanje, Fakultas Pertanian, Universitas Padjadjaran, Kabupaten Sumedang, Provinsi Jawa Barat dengan menggunakan Rancangan Acak Kelompok faktorial dua faktor. Faktor pertama adalah komposisi media tanam yang terdiri atas empat taraf yaitu topsoil, subsoil : kompos ( 1: 1), subsoil : k ompos ( 1: 2), subsoil:kompos (1:3). Faktor kedua adalah interval penyiraman terdiri dari setiap hari, dua hari sekali, tiga hari sekali. Hasil penelitian menunjukkan bahwa subsoil dapat dijadikan media tanam alternatif pengganti topsoil bagi bibit kelapa sawit dengan menambahkan kompos dengan perbandingan 1:3 disertai dengan interval penyiraman yang tepat. Komposisi media tanam subsoil dan kompos (1:3) disertai penyiraman 2 hari sekali menghasilkan pertumbuhan bibit kelapa sawit yang terbaik terutama pengaruhnya terhadap pertambahan tinggi tanaman, pertambahan lilit batang dan bobot kering tajuk. Pemberian kompos pada media tanam subsoil mengurangi pemberian air sebanyak 50%.

Information of legitimacy of oil palm progenies is important to guaranty the quality and to control commercial seeds procedures. A true and legitimate cross will produce progeny which has a combination of their parent's allele. The information could be obtained early in the nursery stage through DNA fingerprinting analysis. Simple Sequence Repeats (SSR) is one of DNA markers used for DNA fingerprinting, since the marker system has advantages to acquire information of allele per individual in population and efficiency diverse allele of progeny and their parents. The aim of the research is to obtain legitimacy of 12 progenies analyzing in the oil palm nursery stage. Thirteen SSR markers were used to analyze 12 crossings number of oil palm. The genotypes data by alleles of SSR inferred and quantified using Gene Marker® Software version 2.4.0 Soft Genetics® LLC and analyzed based on Mendel's Law of Segregation. The result showed based on heredity pattern of progeny and their parent's allele that progenies H were indicated genetically derived from their known parents while progenies from A and G indicated as illegitimate crossing. Probability value for legitimacy of progenies of 9 other crosses has 0.031 and 0.5. Legitimacy analysis of progeny using SSR markers could be used to control the quality of crossing material and earlier selection in the oil palm nursery.

Oil palm requires evenly distributed rainfall throughout the year to achieve optimum yield. This study was aimed to estimate monthly oil palm yield based on depth of rainfall and rainy days data. Yield data were collected from 12 years old of oil palm grown on mineral soils at 15 plantations in North Sumatra. The yield data were monthly data of 2016 and 2017 for database and comparison, respectively. Data of depth of rainfall and rainy days were from 2012-2016. Data were analysed using linear and non-linear correlation between depth of rainfall versus yield and rainy days versus yield at time lag of 0, 6, 12, 18, 24, 30, 36, 42, and 48 months. The results of correlation analysis were used to construct an equation model for estimating monthly yield patterns. Based on values of Root Mean Square Error (RMSE), MeanAbsolute Bias Error (MABE), and Mean Absolute Percentage Error (MAPE) between estimation and actual monthly yield of 2017, it could be conluded that estimation model based on rainy days were more accurate than when it was based on depth of rainfall. The values of RMSE, MABE, MAPE of estimation model based on rainy days were 0,337; 0,275; 15,482%, respectively; while based on depth of rainfall the values were 0,367; 0,296; 16,594%, respectively.

A study to compare amount of N, P, K, and Mg leached from fertilizers had been conducted. Leaching was measured using percolator tubes for six months. Subsoil of Inceptisol collected from an oil palm plantation in North Sumatra was used to fill the tube. Treatments were application of briquette compound fertilizer, granular compound fertilizer, and single fertilizer; all types of fertilizers contained equal amount of N, P, K, and Mg. The results showed that higher amount of leached N, P, and K were found under application of single fertilizers (urea, Triple Super Phosphate/TSP, and Muriate of Potash/MoP) than under briquette and granular compound fertilizer which had slow release characters. Furthermore, amount of leached P was much smaller than leached N, K, and Mg. Residual P from fertilizers after six months was about 99.9%. On the other hand, an intensive leaching of Mg occurred in this study so residual Mg in the end of study was only 25-35%. For N and K, the residual nutrients from fertilizers after six months were about 92-95%.
