Potential Content of Palm Oil at Various Levels of Loose Fruit in Oil Palm Circle
Full text linkHarvesting fresh fruit bunches (FFB) is an important activity in the oil palm plantation industry. This study aimed to analyze the potential content of palm oil at the level of loose fruit that falls on the oil palm circle. Observations were made on five fresh fruit bunches with criteria 1, 3, and 5 respectively loose fruit per bunch that falls on the oil palm circle from oil palm trees that were 22, 16, 12, and 7 years old. All sample fresh fruit bunches were analyzed for potential oil to bunch ratio and oil to wet mesocarp ratio in the analytical laboratory of Bumitama Gunajaya Agro. Content of oil to wet mesocarp ratio in loose fruit 1, 3, and 5 were 48.50%, 51.98%, and 53.21% respectively. While the content of oil to bunch ratio in loose fruit 1, 3, and 5 were 24.19%, 25.52%, and 25.71% respectively. Based on variable of oil to wet mesocarp ratio, the highest potential for oil content occurs in ripe palm fruit with a level of five loose fruit per bunch that falls on that oil palm circle. Five loose fruit per bunch on the oil palm circle can be used as an indicator for harvesters to harvest ripe fruit with optimal oil content.Harvesting fresh fruit bunches (FFB) is an important activity in the oil palm plantation industry.

While the content of oil to bunch in loose fruit 1, 3, and 5 were 24,19 % a, 25,52 % a, and 25,71 % a respectively. The highest potential for oil content occurs in ripe palm fruit with a level of loose fruit 5 grains per bunch that falls on that oil palm circle. Five grains per bunch on the oil palm circle can be used as an indicator for harvesters to harvest ripe fruit with optimal oil content.

Identifikasi Isolat Rizobakteri Indigenos Potensial Sebagai Agens Biokontrol Ganoderma boninense
No full textRhizobacteria is a group of bacteria that colonize roots, affect growth and control plant pathogens. Based on the results of previous studies, 6 isolates have the best ability to control Ganoderma boninense in oil palm seedlings. It is important to characterize them molecularly. Molecular identifications of the selected rhizobacteria isolates were done using the 16S rRNA gene. The results showed that all isolates were identified to have similarity as 5 different species i.e Bacillus paramycoides, Microbacterium paraoxydans, B. albus, B. cereus, and Serratia marcescens based on NCBI database.Rhizobacteria was group of bacteria that colonize roots, affect growth and control plant pathogensBased on the results of previous studies, 6 isolates have the best ability to control G. boninense in oil palm seedlings.

Efikasi Kombinasi Herbisida Metil Metsulfuron dan Asam Asetat pada Lahan Perkebunan Kelapa Sawit (Elaeis gueenensis Jacq.) Menghasilkan
Full text linkOne of the obstacles that resulted in a decrease in palm oil production was the presence of weeds. Weed control needs to be done to suppress weed growth. A mixture of methyl metsulfuron herbicide and acetic acid herbicide can be used to control weeds. This research was conducted in Politeknik Negeri Lampung’s Teaching Farm. This study used a factorial randomized block design with two factors, and each treatment combination was repeated three times. The first factor is the methyl metsulfuron herbicide 20% with 3 level doses: 0 g.ha-1, 45 g,ha-1, and 75 g.ha-1 and the second factor is acetic acid herbicide 20% with 3 level doses: 0 ml.ha-1, 225 l.ha-1, and 315 l.ha-1. The result showed that the combination of methyl metsulfuron herbicide 75 g.ha-1 and acetic acid herbicide 315 l.ha-1 effective reduce weed dry weight up to 5.50 grams at 5 WAA and reduce weed cover percentage to 8% at 6 WAA. The dominant weeds that arises after the application of the methyl metsulfuron herbicide and acetic acid is Asystasia gangetica, Paspalum conjugatum, Panicum dichotomiflorum, Stachytarpeta indica, and Imperata cylindrica.On of the obstacles that resulted in a decrease in palm oil production was the presence of weeds.

Pengaruh Konsentrasi Zat Pengatur Tumbuh dan Bagian Asal Bibit Terhadap Pertumbuhan Vegetatif Pembibitan Tebu
No full textIncreasing sugarcane productivity can be done by providing good quality seedlings. The research objective was to study plant growth regulator concentration and part of seedling origin in sugarcane seedlings. This study was conducted on Pujodadi Village, Trimurjo, Central Lampung from September to December 2020. The study used a factorial randomized block design with two factors and three replications. The first factor is concentration of plant growth regulator which consists of 5 levels: Z0 (0 ml.l-1), Z1 (3.5 ml.l-1), Z2 (7 ml.l-1), Z3 (10.5 ml.l-1) and Z4 (14 ml.l-1). The second factor is the origin of the seedling consists of three parts: P1 (upper stem), P2 (middle stem), and P3 (bottom stem). The results showed that the plant growth regulator concentration significantly increased the percentage of growth and 50% of the seedlings sprouted. The seedling origin of the upper stem showed the best growth compared to the middle and bottom stem. There was no interaction between plant growth regulator concentration and the part of seedling origin on sugarcane vegetative growth.This study was conducted on Pujodadi Village, Trimurjo, Central Lampung from September to December 2020.

Dampak Kebijakan Harga Pembelian Pemerintah Terhadap Produksi Gula Kristal Putih
Full text linkThe policy objective of government purchase price (harga pembelian pemerintah – HPP) of plantation white sugar in Indonesia is to increase the production. However, while the government increase the HPP, the production was decreased. The purpose of this study was to analize the impact of HPP policy on production of plantation white sugar in Indonesia. This study uses ex-post simulation based on econometrics model (build from monthly time series data from 2012 until 2017, consist of 13 equations and estimated using 2SLS method). The result shows that an increase in HPP causes an increase in plantation white sugar production. However, an increase in labor wages cause decreased in production. The increase HPP also causes an increase in producer surplus. Based on producer surplus, the biggest impact of the increase in HPP was felt by the farmers.The policy objective of Government Purchase Price (HPP) of plantation white sugar in Indonesia is to increase the production.

Pertumbuhan Bibit Kakao (Theobroma cacao L.) pada Berbagai Jenis Klon dan Jenis Pupuk Kandang
Full text linkSeveral factors affect the production of cocoa (Theobroma cacao L.), one of which is the quality of seedlings. The quality of seedlings is affected by the type of clones and the composition of the planting media. This study aims to obtain the influence of clone types and types of manure and the interaction between clone types and types of manure on the growth of cocoa seedlings. The study was conducted in the teaching farm and the laboratory of the Politeknik Negeri Lampung from January 2017 to June 2017. The method used was a Randomized Block Design (RBD) factorial pattern consisting of two factors. The first factor is the type of clone consisting of three levels, namely K1 = TSH clone 858, K2 = ICS 60, and K3 = TSH 908. The second factor consisting of four levels namely P0 = control, P1 = chicken manure, P2 = cow manure, and P3 = goat manure. The results showed that the use of TSH 858, ICS 60, and TSH 908 clones had the same effect on all observed variables. However, the use of manure has a significant effect on each variable, but the amount of leaf chlorophyll is relatively the same between clone types and types of manure. There are interactions between clone types and types of manure.Several factors that affect production of cocoa (Theobroma cacao L.), one of which is the quality of seedlings.
