PERANGKAP HAMA OTOMATIS BIBIT SAWIT METODE MENGGUNAKAN MIKROKONTROLER DENGAN SOURCE POWER PANEL SURYA

<p>Oil palm plantations are one of the largest natural resources in North Sumatra. Not a few people make it as an investment vehicle, for example at PT. Perkebunan Nusantara III which is engaged in the management of oil palm and rubber latex plantations. However, to make the investment a success, superior seeds are chosen before planting. Superior seeds must take extra care, but there is one thing that is very detrimental in oil palm nurseries, namely pests that often attack the seedlings in the late afternoon and evening. Therefore, in the treatment of seedlings, spraying poison with a certain dose. If it is wrong in the dose of poison, the seeds will be further damaged by the poison. In this case, the idea was raised to create an automatic pest trap as an automatic trap instead of poison so as to minimize the problems that occur. In this study using Arduino uno, LDR sensors, relays, lights, solar panels, solar chargers, and 12v battery. Which is Arduino Uno as a microcontroller, LDR sensor as an ambient light reader, and relay as an automatic switch on the lamp. The source of electricity comes from solar panels and a solar charger to charge the battery. With this tool, it is hoped that it can help the work of plantation employees in caring for oil palm seedlings.</p>

PEMANFAATAN LIMBAH SAYUR, MAKANAN DAN JERAMI PADI DENGAN BIOAKTIVATOR Trichoderma sp. SEBAGAI MEDIA TANAM BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.) DI PEMBIBITAN AWAL

Alternative growing media are needed to overcome the shortage of top soil which generally occurs in oil palm nursery. Organic waste such as vegetables, food and rice straw is one of the ingredients that can be used as a growing medium because it is easy to find and has a high nutrient content. These wastes need to be decomposed to make them more easily absorbed by plants, therefore it is necessary to add bioactivators such as Trichoderma sp. for speed up the decomposition process. The purpose of this study are to obtain alternative growing media for organic waste, determine its effect on oil palm seedlings, and determine the best growing media treatment. This research conducted at experiment areal in Cibitung, from November 2021 until August 2022. This research was arranged in non factorial block complete design with four treatments, consist of P0 (kontrol sub soil), P1 (50% vegetable waste+50% sub soil+Trichoderma sp.), P2 (50% food waste+50% sub soil+Trichoderma sp.) dan P3 (50 rice straw+50% sub soil + Trichoderma sp.). Every treatments repeated 3 times and have 3 samples, so there were 36 seeds. The data was analysis of variance, if test result was significant at 5%, then continued by BNT. The results showed that organic waste could be used as alternative growing media for oil palm nursery, and significantly effected to plant height (3 MAP), stem diameter (2 and 3 MAP), leaf area and biomass. The best treatment based on morphological and physiological response is rice straw and Trichoderma sp.

Dynamics of Nutrient Availability of Inorganic Fertilizers in Oil Palm (Elaeis guineensis Jacq) Nursery

Inorganic fertilizers that are applied take a certain time to be available in the soil. The application distance between types of fertilizers is needed with the aim of reducing antagonistic properties, both antagonistic properties between nutrients and between types of fertilizers so as to increase the effectiveness of fertilizer absorption. The purpose of this research study the pattern of nutrient release and the interaction of several chemical fertilizers at the oil palm nursery stage. This research was divided into 2 stages, namely the preliminary stage to determine the optimum dose of each type of fertilizer and the stage of testing the antagonism of 2 different types of fertilizers from 5 types of fertilizers, namely Urea (N), Rock Phosphate (P), MOP (K), Kieserite (K), and HGFB (B). The experimental design used a non-factorial Randomized Block Design, with 45 treatments and 4 replications. The results showed that the optimum doses of the three leaf nutrients were obtained at 40 g/seed for RP, 45 g/seed for K, and 50 g/seed for Borate. The optimum nutrients for N and K fertilizers have not been obtained, so the highest dose from the test level is used, which is 80 g/seed respectively. The results of statistical analysis show the ideal distance of application time between RP and MOP fertilizers, RP with Kieserite, RP with HGFB, MOP with Kieserite.

The Improvement of Oil Palm Seedling through Shade, Manure and Organic Liquid Fertilizer in Ultisol Media

The development of oil palm nurseries in Bengkulu is constrained by plant media, such as ultisol soil, which has low nutrients. Nutrients in ultisol can be equipped by organic matters such as manure and liquid organic fertilizer (LOF). Moreover, the light intensity also could affect seeds growth. This research aimed to determine the improvement of oil palm in pre-nursery as affected by LOF, types of manure application, and shade to obtain the best treatment combination. The research was conducted from June until September 2021 in Beringin Raya, Bengkulu city. The study was arranged in a split-plot design in a completely randomized block design consisting of 3 factors with three replications. The main plot was shade percentage ((N1=50% dan N2=75%), the subplot was liquid organic fertilizer doses ((B1=0%, B2=5% and B3=10%), the sub subplot was the types of manure (P1=cow manure, P2=chicken manure, P3=goat manure, and P4= without manure). The observation was made on the growth components of oil palm seedlings until 3.5 months. There was an interaction between shade, LOF, and types of manure to the number of leaves. There was no interaction between LOF and types of manure. The shade did not affect the growth factors of the seeds. Applying 10% LOF can improve the growth of oil palm seedlings. Chicken manure has the highest variable value on the hump diameter and the number of leaves seedlings.

Struktur Komunitas Artropoda di Pembibitan Kelapa Sawit

Nurseries are one of the essential agronomic activities in oil palm cultivation. Oil palm seedlings are cultivated on a large scale, different from nurseries for other plantation commodities. The nursery expanse comprises various biotic components, one of which is Arthropods. This study aims to determine the Artropod community and its function in oil palm nurseries. The research was carried out at two nurseries, Nagari Gunung Medan and Nagari Kurnia Selatan, Dharmasraya Regency, West Sumatra Province. Sampling using the pitfall trap, yellow pan trap, insect nets, and direct collection methods. The results showed that the Arthropods that make up the oil palm nursery ecosystem were insects and spiders. Arthropods in oil palm nurseries act as phytophages, predators, parasitoids, and detrivores. Phytophage insects found in oil palm nurseries were 700 individuals consisting of 4 orders, nine families, and 14 genera/species. Predatory insects, parasitoids, and detritivores were found in as many as 466 individuals consisting of 5 orders, 14 families, and 16 genera/species. There are two species of spiders in oil palm nurseries: Pardosa sp and Oxyopes javanus. Valanga sp was the species with the highest number of individuals in oil palm nurseries.

Sistem Pendukung Keputusan Menentukan Kelayakan Lahan Pembibitan Menggunakan Metode Multi Attribute Utility Theory

Determining the location of plantation land is a very important role to support the development of oil palm plantations and also factors that support plantations to produce oil palm fruit with good quality. To help companies produce palm oil with the best quality fruit, it is necessary to have the appropriateness of the land used for oil palm planting from the seedling process. PT. Fajar Agung experienced several difficulties in making a decision to choose suitable land for oil palm seedlings, so making a decision took a long time. In determining the feasibility of oil palm nurseries, a decision support system is needed by applying the Multi Attribute Utility Theory (MAUT) method. The purpose of this study is to implement a decision support system in determining the feasibility of oil palm nurseries using the Multi Attribute Utility Theory (MAUT) method to be more effective and efficient for the leadership in making a decision so that the company does not suffer losses. From the calculation results to be used as an oil palm nursery with an assessment that is more than 0.500 which is declared feasible there are 6 alternatives, namely A5 (Block 5), A6 (Block 6), A7 (Block 7), A8 (Block 8), A11 (Block 7A ) and A1 (Block 1) with the highest score of 0.838. MAUT method can be used as an alternative method to perform calculations based on predetermined criteria so as to facilitate decision making.

Efficacy of Microbial Concortia with Liquid Organic Fertilizer for Leaf Spot Disease Control on Oil Palm Nursery

Leaf spot is the primary disease on oil palm nurseries. The symptom of the disease is leaf spots are round to oval in shape and vary in color from yellow to brown to black. The initial size may be as small as a pin point. Some leaf spots initially appear as lesions. During disease development, leaf spots will have a contrasting colored edge or halo - e.g., brown spot with a yellow halo, tan center with brown edge or gray center with black edge and a yellow halo. As the leaf spots expand in size, the shape and coloration may change. As the disease progresses, leaf spots often coalesce (merge together) to form large areas of blighted tissue. If the disease continues to develop, leaflets or the entire leaf may die prematurely. The disease also causes stunted and even plant death. Disease control methods that rely primarily on biological agents and do not include fertilizers are less effective in the field. Therefore, the development of organic fertilizer formulations and the use of biocontrol agents are expected to assist oil palm nurseries in suppressing leaf spot disease. The purpose of this study is to investigate the effect of organic fertilizer and biocontrol agents on leaf spot disease. The results showed that the treatment of Organic Fertilizer and biocontrol agents was able to reduce 47.19% leaf spot disease after five weeks of application.

EVALUATION OF GROUND SERPENTINE ROCK AND GROUND MAGNESIUM LIMESTONE AS MAGNESIUM SOURCES FOR OIL PALM NURSERY SEEDLINGS

Treatment of ground magnesium limestone and ground serpentine by boiling in 5 ml of concentrated nitric (HNO3) acid and 10 ml of concentrated hydrochloric (HCl) acid for 1, 2, 4, 8 and 16 hours in the laboratory showed mean magnesium oxide (MgO) content of 18.2 and 29.20 per cent, respectively. The experiment for the two sources of magnesium (Mg) was carried out on oil palm nursery seedlings grown in large polybags with coarse river sand as the medium of growth. The rates were 5, 10, 20 and 30 g of MgO, applied in planting holes at the time of transplanting of three-month-old pre-nursery seedlings. Initially, up to four months, the leaf 3 Mg levels were slightly higher in ground serpentine treatment, although the difference in values was statistically not significant when compared to the rest of the treatments. As the age of the seedlings increased, there was a continuous decline in leaf Mg levels for all treatments. At the eighth month, the Mg levels of oil palm leaves grown with ground magnesium limestone were significantly higher than the control treatment with no Mg. The source of Mg had no influence on the vegetative growth of seedlings, as all the treatments including control showed no significant differences for the measured growth parameters. In conclusion, ground serpentinite rock is comparable to ground magnesium limestone as a source of Mg. The rate of 30 g MgO per plant, when placed in the planting hole, is insufficient to meet the oil palm needs after the fourth month of application. Higher rates or different methods of application may be needed and to be studied in subsequent trials.

THE EFFECT OF ANTAGONIST PLANTS IN SUPPLYING THE PROGRESS OF THE EVENT OF GANODERMA SP ROOT DISEASE

Activity Testing the Effect of Antagonist Plants in Suppressing the Development of Incidence of Root Rot Disease Ganoderma sp. aims to determine the effect of antagonist plants in suppressing the development of stem rot disease incidence of Ganoderma sp. in oil palm nurseries. The study used a randomized block design with 7 treatments, namely Ganoderma+ginger isolate, Ganoderma+turmeric isolate, Ganoderma+lemongrass isolate, Ganoderma+temulawak isolate, Ganoderma+garut isolate, Ganoderma isolate and control. Each treatment with 5 replications with 2 sample plants. The parameters observed were the development of disease incidence through symptoms, height and number of leaf midribs of oil palm seedlings. The data were analyzed using the SPSS program. The effect of the treatment was analyzed by using fingerprints. If there is a treatment that has a significant effect, further tests are carried out with Duncan's Multiple Distance Test (DMRT) with a level of : 0.05. Based on the test results, it was found that the incidence of Ganoderma stem rot disease was the fastest, highest and most developed in each observation, namely in the treatment using ginger and lemongrass antagonists. While the lowest incidence of disease was found in the treatment of arrowroot, turmeric and temulawak. These antagonist plants have exudate containing antibiotics that can inhibit the growth of the Ganoderma fungus. The development of oil palm seedling plant height is strongly influenced by the physical properties of the soil and the presence of Ganoderma pathogens. While the Ganoderma pathogen did not affect the development of the number of leaf midribs, but only caused changes in leaf color such as necrosis.

The Effect of Irrigation Time and Slow-Release Fertilizer on Oil Palm Seedlings Under Controlled Drip Irrigation System

Irrigation and fertilization are critical aspects in oil palm nurseries, so they need to be appropriately managed. Automatic drip irrigation technology has the advantage of saving water and labour usage. On the other hand, correctly applying slow-release fertilizer can fulfil the need for oil palm seedlings. The combination of drip irrigation and the application of slow-release NPK fertilizer can increase the effectiveness of maintaining oil palm seedlings. This study aims to obtain the best watering time and rate of slow-release NPK fertilizer on the growth and performance of oil palm seedlings in the main nursery. A field study was conducted since June 2021 until August 2021 at the Oil Palm Nursery Unit in Politeknik Negeri Lampung, Indonesia. The experiment arranges in split-plot design in randomized block design with three replications. The watering time is the main plot, and the slow-release NPK fertilizer rate is the subplot. The results showed that application of drip irrigation system with watering time in the morning, midday, and afternoon significantly affect stem diameter and number of leaves at three months after observation. The rate of 20 g plant-1 slow-release NPK fertilizer best-affected plant height, stem diameter, number of leaves, leaf area, and greenness index.

Effectiveness of Various Foliar Fertilizer on the Growth and Performance of Oil Palm (Elaeis guineensis Jacq.) Seedlings in Main Nurseries

Fertilizer can be applied through soil and leaves. Fertilizer application through leaves is more effective than soil application due to faster nutrient absorption. This study aims to determine the effectiveness of applying various foliar fertilizer compositions on the growth and performance of oil palm seedlings. The research was conducted from April 2020 to September 2020 at the Oil Palm Nursery Unit at Politeknik Negeri Lampung. A single factor in a completely randomized design with four replications was used in the experiment. The treatment involved the nutrient composition of foliar fertilizer consisting of five levels, namely control (no fertilizer), NPK 20-15-15, NPK 27-18-9, NPK 11-8-6, and NPK 27.5-5.5-4.8. Measurements were made on seedling height, stem diameter, number of leaves, leaf greenness, rachis length, and leaflet length. The data were analyzed by means of variance, followed by orthogonal contrast if the result was significantly different. The results showed that the application of foliar fertilizers could increase the growth of seedling height, stem diameter, number of leaves, leaf greenness index, rachis length, and leaflet length. Generally, a foliar fertilizer application gives better results than without a foliar fertilizer application (control). There was no difference in the powder and liquid foliar fertilizer effect on increasing the growth of oil palm seedlings. The formulation of NPK 20-15-15 and NPK 11-8-6 foliar fertilizer had a better effect on the leaf greenness index of oil palm seedlings.

Automatic Watering System for Oil Palm Seeds

Nursery of oil palm is a period of preparing oil palm for approximately 3 months. However, in watering still using the manual method, this method still has a weakness, namely by pulling the water hose so that farmers of oil palm have to work hard and drain energy and also take a long time. From these problems, a solution was made by making an automatic palm seed watering system using the rtc module as the scheduling of the watering system and NodeMCU as the brain of the system's main process and using the blynk application as a notification output in the form of messages. As a result, the automatic watering system can work optimally if the time of the watering process has been determined and the system is able to send notifications to the blynk and display messages on the results of the watering process, with this automatic watering system it can help the work of oil palm nursery farmers.
