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.

Abstract

The study aimed to find the media composition and watering frequency through drip irrigation technology, which is appropriate to support the growth of vanilla plants in polybags. The research was conducted in the STIPER Dharma Wacana Metro experimental garden from April to July 2020. The first factor is the composition of the planting medium, namely soil + manure, soil + manure + rice husks, soil + manure + sand, and soil + manure + cocopeat. The second factor is watering frequency, namely 1, 2, and 3 times a day. Each treatment was repeated three times. The variables observed included plant height (cm), number of leaves (strands), shoot fresh weight (g), root fresh weight (g), and biomass dry weight (g). The use of mixed media of soil, manure, and cocopeat is the best media composition by producing a root wet weight of 8.0 g and a dry weight of 7.2 g. The frequency of watering three times a day resulted in the best height of vanilla plants being 51.8 cm compared to the frequency of watering once and twice a day. There was no interaction between the composition of the growing media and the frequency of watering on vanilla plants growth in polybags.

Abstract

Input factor is one of the determinator the quality and response of the tea plant growth. Inorganic fertilizer input still dominates in Indonesian plantations due to the lack of comprehensive evaluation of organic fertilizers, especially in liquid form. This study aims to determine the effect of inorganic and organic liquid fertilizer applications and the frequency of their application on the growth of tea plants. The experiment was carried out based on a Randomized Block Design (RBD) consisting of six treatment combinations, including tap water application once a week, tap water once every two weeks, 1% urea once a week, 1% urea every two weeks, 1% POC once a week and 1% POC once every two weeks. Experiments were carried out on yielding tea plants with the 3rd year of pruning stage. The parameters observed were shoot production (kg.plot-1), weight of banji and pekoe (g.100g-1) and the ratio of banji/pekoe. The results showed that the application of urea foliar fertilizer and liquid organic fertilizer with different application frequencies did not have a significant effect on each observed parameter. Application of 1% liquid organic fertilizer once every two weeks has the potential to increase tea productivity by showing a relatively high production of tea (6.88 kg.plot-1) compared to other treatments.

Abstract

Sugarcane (Saccharum officinarum L.) play an important role for sugar consumption in Indonesia. Problem found with sugar industry in Indonesia is the low productivity of sugarcane because of cultivation techniques caused by low soil fertility. This research aimed to determine effect of Plant Growth Promoting Rhizobacteria (PGPR) and vermicompost in increasing the growth of sugarcane. The research method used Randomized Block Design (RBD) consisted of 2 factors with a combination of 6 treatments. The first factor was A1 = without PGPR A2 = PGPR (10 ml.L-1) and the second factor was P1 = 3.5 t.ha-1 (50% vermicompost recommended fertilizer), P2 = 7.t ha-1 (100% vermicompost recommended fertilizer) and P3 = 10.5 t.ha-1 (150% vermicompost recommended fertilizer). Variables of this observation are plant height, number of tillers, number of stems, number of internodes, stem diameter, brix value and the yield of sugarcane. At the age 7 months after planting, the treatment of PGPR application at a vermicompost dose of 7 t.ha-1 (78.46 t.ha-1) was able to reduce the need for a vermicompost dose which was shown by a higher yield value compared to without PGPR application with vermicompost 3.5 t.ha-1 and vermicompost dose of 7 t.ha-1. A higher stem weight obtained in the PGPR treatment when compared to the treatment without PGPR. At a vermicompost 7 t.ha-1 and a vermicompost 10.5 t.ha-1 showed a higher stem weight compared to vermicompost 3.5 t.ha-1.

Abstract

Black pepper is a spice with a spicy taste and a distinctive aroma that has become known as the King of Spices. The distinctive aroma of black pepper comes from the volatile compounds that make up the essential oil of pepper. Black pepper essential oil has antimicrobial properties that can relieve respiratory infections and relieve muscle disorders. The acquisition of pepper essential oil from the distillation process is influenced by operating conditions. The aim of this study was to identify the composition of black pepper essential oil compounds using GCMS and to optimize the operating conditions (material size, solvent ratio, and distillation time). The method used to determine the optimum condition is using the Response Surface Method (RSM). The results showed that the highest yield of black pepper essential oil from this experiment is 5.14%. The empirical model was also suitable for the experiment and the optimum conditions for producing the maximum pepper oil yield 5,81% were 40 mesh of material size, 0.12 (g.ml-1) of solvent ratio and 162 minutes of distillation time. GCMS test results showed that the main constituents of pepper essential oil are caryophyllene, ocimene, limonene, carene, and a-pinene.

Abstract

Harvesting 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.
