Abstract

One 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.

Abstract

Coffee is one of the plantation products with significant importance in the economy of Kerinci Regency, and several obstacles have been reported in agroindustry development. This study is focused on designing a strategy to develop the industry in the region. The study was conducted in Kerinci Regency from January 2017 until October 2017. The data was collected by observation, questionnaires, and in-depth interviews through Focus Group Discussion (FGD). In addition, research analysis used internal and external factor methods, internal and external matrices (IE Matrix), and SWOT matrices. The result show the value of the internal and external factors obtained to be 2,759 and 2,888, respectively. When mapped, the IE matrix value is in cell V (five). However, the suitable strategies are the growth and stability strategy, essential for market penetration and product development. Based on AHP analysis, the three main strategic priorities to be applied  are land expansion (0,230), guidance and facilitation of the market information (0,178), and infrastructure improvement (0,124)

Abstract

The 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.

Abstract

Rhizobacteria 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.

Abstract

Root trainer technology can be an alternative for rubber plant nursery that have ease in transportation and distribution. Organic materials which are lightweight, porous, and contain nutrients are considered suitable for root trainer growing media. This research was carried out at Sungei Putih Research Center Greenhouse, Deli Serdang from January - May 2019. The research was arranged based on a Randomized Block Design (RBD) with 4 media combination treatments namely: top soil (P0), empty bunches and manure (P1), empty bunches and rice husks (P2), and empty bunches and solid decanters (P3). The results showed that the planting media did not have a significant effect on plant growth including stem diameter, plant height, and number of leaves, as well as the percentage of successful grafting. The treatment of oil palm empty fruit bunches and solid decanter gave better growth than other organic materials. The availability of empty bunches and solid decanter in North Sumatra is relatively abundant so that it can support rubber nurseries throughout the year.

Abstract

Climate is one of the factors that influence the growth, and production of palm oil, one of the most important climate elements is rain. Rain is the main source of water in meeting the needs of palm oil trees. This research aimed to map the climate type of Bintang Bayu region and to determine the trend of rainfall in 10 years (2010-2019) in Bintang Bayu Sub-district, Serdang Bedagai District, Sumatera Utara Province. This research used Geographical Information Systems (GIS) and descriptive-analytical methods. Rainfall data derived from satellite imagery (Data Chips-2.0, UCSB) obtained from the Meteorology and Geophysics Agency (BMKG) Stasiun Klimatologi region of Deli Serdang which was used as the basis for determining dry and wet months based on Schmidt-Ferguson. Evaluation of rainfall suitability was carried out by comparing the annual rainfall observation data with the Palm Oil Land Suitability Criteria based on the Indonesian Center for Agricultural Land Resources Research and Development. The results showed that Bintang Bayu Sub-district had climate type A (tropical rain forest), in which, in the area with climate type A was suitable for palm oil plants. Based on the distribution of annual rainfall, there were two distributions of rain, that were 2,500-3,000 mm.year-1 and 3,000-3,500 mm.year-1, there were no areas with an annual rain distribution of 2,000-2,500 mm.year-1, thus the Bintang Bayu region is included in the S2 class. In ten years, there was an increase in rainfall in January, May, July, and October while in other months there was a decrease in rainfall.

Abstract

Increasing 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.

Abstract

Several 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.
