Abstract

Heritability of fruit characters, such as fruit weight, husk weight, husk thickness, sheal weight, endosperm (water) weight, albumen weight, copra weight, oil content, fruit length and ftuit width. have been estimated on seven coconut populations. The results showed that most of the fruit components of Malayan Red Dwarf (MRD) and Malayan Yellow Dwarf (Mm)had relatively high heritability (>0.80), except fruit weight of MRD (0.74) and albumen weight of MYD (0.78). On the other hand, the heritability of those characters in tall populatidns varied between population. All of fruit characters on Polynesian Tall (PYT) and Seruwai Tall (SAT) had relatively high heritability (>0.80). On West African Tall (WAT), most Of the heritability of the fruit characters were relatively high (>0.80). except husk weight (0.75). endosperm weight (0.79) and oil content (0.41). Heritability of seven characters of Bali Tall (BLT) were relatively high, but those of three characters were relatively low; i.e. husk weight (0.52). fruit width (0.56) and husk thickness (0.71). Three fruit characters of Rmnell Tall (RLT) shown higher heritability. those are husk thickness (0.87), endosperm weight (0.92) and fruit length (0.90).

Abstract

An experiment to study heritability, general combining ability (GCA), and specific combining ability (SCA) of some traits in oil palm progeny was conducted at Kebun Surya Adi, PT. Bina Sawit Makmur, Sampoerna Agro, Ogan Komering Ilir, Sumatera Selatan, from July 2006 until September 2008.  The research was arranged in alpha design with two replications, 50 progenies and 12 palms for each replication, respectively. The results showed that broad sense heritability estimates were high for mesocarp to fruit, oil to fresh mesocarp, and  kernel to fruit content ratios, and β-carotene content; medium for bunch number and oil to bunch ratio; and low for fresh bunch and fruit to bunch ratio. The general combining ability (GCA) of bunch number, mesocarp to fruit, oil to fresh mesocarp, and kernel to fruit ratios and β-carotene content were highly significant. Similarly, the specific combining ability (SCA) of mesocarp to fruit, oil to fresh mesocarp, and kernel to fruit ratios and β-carotene content were also highly significant.   Key words:  Heritability, combining ability, Elaeis guineensis Jacq., alpha design, β-carotene

Abstract

Penelitian ini dilakukan untuk mengetahui pengaruh tingkat kematangan kompos tandan kosong sawit dan penggunaan mulsa limbah padat kelapa sawit terhadap produksi tanaman tomat (Licopersicon esculentum Mill.) pada wilayah dengan tanah ultisol. Percobaan menggunakan rancangan petak terbagi (Split Plot Design) dengan mulsa sebagai petak utama dan kematangan kompos sebagai anak petak. Mulsa terdiri dari empat jenis yaitu tanpa mulsa, cangkang, fiber, dan cacahan TKS. Sedangkan tingkat kematangan kompos terdiri dari 5 taraf yaitu tanpa kompos, kompos 4 minggu, kompos 6 minggu, kompos 8 minggu dan kompos 10 minggu. Bahan yang digunakan adalah tomat (Lycipersicon esculentum Mill.) varietas Ratna. Kompos 8 minggu memberikan nilai C/N ratio terendah dibandingkan umur 4, 6, dan 10 minggu yaitu 35.16. Kompos umur 8 minggu menghasilkan nilai N-total, P, dan Mg tertinggi dibandingkan 3 kompos lainnya yaitu 1.34 %, 0.08 %, dan 0.25 %. Kompos dengan C/N rasio lebih rendah dan kandungan hara yang lebih tinggi memberikan pertumbuhan vegetatif tomat yang lebih baik dibandingkan kompos lainnya. Kompos 8 minggu dan mulsa fiber menghasilkan bobot panen dan jumlah buah terbanyak yaitu 436.56 gram dengan 16 buah. Jumlah dan bobot buah yang dihasilkan pada penelitian ini lebih rendah bila dibandingkan budidaya tomat pada umumnya karena kondisi tanah ultisol yang masam. Nilai KTK yang rendah mengakibatkan terganggunya penyerapan hara tanaman. Bila dibandingkan kontrol, penggunaan kompos 8 minggu meningkatkan bobot buah 52.59 % dan jumlah buah sebesar 82.53 %. Penggunaan mulsa cangkang menunjukan pengaruh negatif terhadap pertumbuhan dan produksi tanaman tomat.

Abstract

This study aimed to investigate the effect of compost from oil palm empty fruit bunches with different ages, mulching oil palm waste, the levels of heavy metals in compost and its influence on the growth and yield of chili. Composting was assisted by the starter (PromiTM) with a dose of 0.5 kg per ton of chopped bunches. Composting treatment distinguished by the composting time namely 4, 6, 8 and 10 weeks. Mulch treatment consisted of shell, fiber and empty fruit bunch chopped. The empty fruit bunch compost had the potential to decrease the soil acidity because the pH of 7.89- 8.66. The EFBs compost contained Boron of 7.7-10.7 ppm, 12-24.8 ppm of Cuprum, 0.05 to 0.24 % of Fe, 26.5-89.7 ppm of Mn, and 9.1-10.8 ppm of Na. This compost contained heavy metal Cd and Hg. Cd was detected in amount of 0.08 to 0.25 ppm. Hg was detected in amount of 12.9-19.5 ppm. Meanwhile, Pb and As were not found. Cd did not exceed the threshold. On the other hand, Hg was detected exceeding the threshold but did not affect the growth and yield of chili. Organic mulch from palm oil wastes did not significantly affect on the chili yield. Shell mulch had a negative influence on the growth and yield of chili.

Abstract

Prasetyo et al, 2019. Performance of Palm Oil in Dry Season in South Sumatera: Effect of Fertilizer on Vegetative Growth and Status of Nutrient. pp. 60-66.Most of the oil palm plantations in South Sumatra Province are planted in acid soils (Ultisol and Oxisol). The main limiting factor in acid soils is high acidity with low fertility. This condition is coupled with the typical climate conditions in South Sumatra, namely the existence of a strict boundary between the rainy and dry seasons. When the dry season, it is not uncommon to find water deficits. This study was conducted to determine the relationship between water deficit events and vegetative growth and nutrient content of oil palm. This study was carried out by exploiting data in fertilization experiments. Fertilization experiments using factorial design N3P2K3Mg2 (higher order partially confounded interactions) and each plot consisted of 64 trees. The results of the study showed that in general the water deficit events in 2014 decreased 4-6 frond per year in the same year and decreased 2-6 frond per year in 2015. Increased K content in the leaves will increase frond production. The optimum K content to maintain a fixed 24 frond production is 1.1%. This study can be used as initial information for management of fertilization management in the event of a water deficit.

Abstract

Pratama et al, 2018. Oil Palm Breeding Program Strategy for Suboptimal Area in PT Binasawit Makmur  . JLSO 7(1):26-36. Suboptimal areas have great potential to be used an alternative land for cultivation of oil palm.We needed superior oil palm material to be able to grow well on that land. PT. Binasawit Makmur (BSM) through the Breeding Unit has developed a strategy regarding the assembly of superior material oil palm drought resistant. Therefore, this research aimed to develop  a strategy regarding breeding program in suboptimal lands of PT Binasawit Makmur.  The strategies used were  introducing, evaluating, and selecting genetic material based on productivity components (total and weight of fresh fruit bunches/ha, extraction rate) and high increment.  In addition, the efforts have been made to obtain drought tolerant material are conducting a progeny trial (DXP Trial) on mature palm to obtain drought tolerant in the dried season. Based on the results of the progeny trial, both of parents were traced to a crossing program. Currently, the seeds of the crossing have been obtained to confirm the results of the research on the nursery scale. In the nursery trial, research will be conducted to measure the proline content, stomata and chlorophyll content. Selection in the mature palm DXP progeny trial was followed by application a molecular tool such as SSR and SNP. Through this approach, a superior genetic material in terms of productivity and also drought tolerance can be developed and therefore can be used for recombination and release of new varieties.

Abstract

Nugraha et al, 2019. Solubilization of Inorganic Phospate by Burkholderia spp. Associated with Oil Palm Rhizosphere in Mineral Acid Soil. JSLO 8(1):86-93.Phosphate Solubilizing Bacteria (PSB) play important role by enhancing phosphate availability bounded with Al3+ or  Fe3+ in acidic soils to oil palm plants through release the inorganic phosphate by enzyme or organic acids solubilization. The aims of this study were to isolate of PSB from oil palm rhizosphere and to conduct a comparative analysis of the solubility inorganic phosphates source by selected PSB. The ability of 15 selected PSB to grow and solubilize aluminum phosphate (AlPO4) and iron phosphate (FePO4) was examined and identified. The highest phospate solubilising efficiency showed K3.1 isolate with phosphate solubilization index 3.2 on NBRIP media. Quantitative analysis revealed that isolate K3.1 solubilized 53.52 mg/mL phosphate in 5 days after being inoculated in AlPO4 containing liquid medium, isolate A4 solubilized 63.45 mg/mL phosphate in 5 days after being inoculated in FePO4 containing liquid medium accompanied by a decrease in pH of the growth medium. Based on the 16s rRNA gene sequence analysis, isolate K3.1 and A.4 were closely related to Burkholderia arboris and Burkholderia gladioli. This potential isolates can be used in order to make oil palm crops more sustainable especially on marginal soil with low pH and less dependent on inorganic P fertilizers.
