Diversity Of Weed Species In Cocoa Plantations In Banyuwangi, East Java, Indonesia

Syaiful Khoiri — 2023-09-22

Cocoa (Theobroma cacao L.) is one of the important plantation commodities in Indonesia. However, one of the factors that can affect productivity is weeds because weeds compete with cocoa in getting water, sunlight, nutrients, air, and space to grow. One of the largest cocoa plantation areas in East Java is the Banyuwangi district. Information about the types of cocoa weeds in Banyuwangi is unknown even though weeds in one area are different from another. Weed can reduce the production of cocoa. So, This study is important for determining appropriate control methods. This study aimed to determine the type, diversity, and abundance of weeds. The research method used in this study was a survey with a square-plot size. All weed samples were identified. The results showed that there were twelve types of broadleaf weeds, three types of grass weeds, one type of sedge, and one type of fern. The highest importance value index (IVI) was found in Ottochloa nodosa at 40.91%. The diversity of weeds was in a medium category. Weed diversity in cocoa plantations in Banyuwangi was different from other areas in Indonesia. The results of this research contribute to providing information on the diversity of weeds that can be used in determining weed control strategies in cocoa plantations.

Comparative Analysis Of Oil Palm Farming Patterns Between Plasma And Independent Farmers In North Musirawas Regency

Febrina Nur Annisa — 2023-09-10

This study aims to analyze the influence of partnership types on agricultural outcomes and farmers' income in oil palm plantation enterprises. Data were obtained from 10 farmers divided between plasma and independent partnership types. The observed variables included partnership types, land area, quantity of fertilizer use, herbicide use, and income. Analysis was conducted using descriptive statistical methods, Pearson correlation, paired t-test, and analysis of variance (ANOVA). The results of the study indicate that partnership types significantly affect agricultural outcomes and farmers' income. Plasma farmers tend to have better agricultural outcomes and higher income compared to independent farmers. Additionally, land area and fertilizer use also exhibit significant differences between partnership types. However, herbicide use does not show a significant difference between the two partnership types. In conclusion, partnership types have an impact on agricultural outcomes and farmers' income in oil palm plantation enterprises. These findings hold important implications for policy and strategy development that focuses on enhancing farmers' welfare within the plasma partnership.

Mapping Age Of Oil Palm Trees Using Google Earth Engine Cloud Computing In Pt. Scp, Pulang Pisau Regency

Akbar Cahyadhi Pratama Putra — 2023-09-15

The aim of this research is to utilize remote sensing data and use the GEE platform to detect the age of oil palms using Landsat 8 OLI data at the Sebangau Kuala Plantation in Pulang Pisau Regency, Central Kalimantan. This research was analyzed using the Google Earth Engine using FCD (Forest Canopy Density) analysis. The results of the model correlation with the conditions of the year of planting in the field through ARESTA (area statement) are 0.63 or have a strong relationship. The RMSE (Root Mean Square Error) value of the FCD (Forest Canopy Density) model is 0.661, which means that the error value is small and can be used as a model reference. The use of remote sensing and GEE makes the process of mapping the age of oil palm more effective. The results of the research show that mapping the age of oil palm using GEE is very efficient based on computing time, so it is very suitable for use in oil palm plantations.

The Efficacy Of Isopropyl Amine Glyphosate 165 Sl Herbicide Effect On Weed Control Of Coconut Cultivation

Doni Hariandi — 2023-09-15

Coconut plants are an important commodity for Indonesian people. In the cultivation process, coconut plants need a suitable environment for growth and production. One of the problems in cultivation is weeds. Weeds have a negative impact on cultivated plants, therefore appropriate control measures are needed. So far, the most effective weed control is chemical methods using herbicides. One of the herbicides that can be used is the herbicide with isopropyl amine glyphosate 165 SL. The aim of the experiment was to determine the efficacy of the herbicide isopropyl amine glyphosate 165 SL for controlling weeds in coconut cultivation was conducted from February to June 2022 at Pariaman City, West Sumatra Province. The experimental units were laid out according to a Randomized Block Design with 7 treatments and 3 groups as replications. The treatment was herbicide isopropyl amine glyphosate 165 SL at doses of 3.50 l ha^-1, 5.25 l ha^-1, 7.00 l ha^-1, 8.75 l ha^-1, 10.00 l ha^-1, manual weeding and control (without weeding). The results of the research show that (1) The herbicide isopropyl amine glyphosate 165 SL can generally control weeds in coconut cultivation up to 12 weeks after application because the weed biomass in the treatment plot is relatively the same as manual weeding and is lighter than the control; (2) Herbicide isopropyl amine glyphosate 165 SL with a dose range of 3.50 l/ha – 10.50 l ha^-1 up to 6 weeks after application does not show symptoms of phytotoxicity in coconut plants.

Innovation In Processing Of Areca Peel Waste Into Organic Polybags As Nursery Media

Adinda Salwa Rahmasari — 2023-09-25

Polybags are planting media that are often used as nursery media. However, the use of polybags can cause the environment to become polluted due to the use of plastic, which is difficult to decompose by soil microbes, and also can destroy planting media and caused root damage in planting process to the field. One way to overcome these problems is to use organic-based nursery containers that are environmentally friendly. Poliarec (Polybag Organic of Areca catechu) is an organic polybag derived from areca peel waste. This product was made in 3 stages, first stages by making of polybags using 250 gr of areca peel waste to produce one unit of polybag measuring 10x10 cm. The second stage was carried out weight and density tests, and the third stage was carried out functional tests by conducting planting experiments on horticultural seeds. Poliarec can be planted directly on the ground because it is easily decomposed by microbes so that it can simultaneously become fertilizer and is able to maintain soil moisture. The density test showed, Poliarec has a low density category type based on SNI standards. It can function well as a seedling media after a functional test on chili seeds for 4 weeks. From this functional test, it was also found that Poliarec can save water usage because watering can be done once every three days. The direct benefits of this creative and innovative work are in addition to support sustainable agriculture by reducing the use of plastic polybags, and also will increasing the economic value of areca peel waste.

Identification And Parasitization Of Parasitoids Against Setothosea Asigna In Oil Palm Plantations In Dharmasraya District, Indonesia

Zahlul Ikhsan — 2023-09-27

Setothosea asigna poses a significant threat to oil palm plantations, necessitating effective control measures. This survey-based research, utilizing Purposive Sampling, identifies parasitoids and evaluates their effectiveness in Dharmasraya oil palm plantations, a crucial palm oil-producing region in Indonesia. The selected criteria encompass plantations aged 6-15 years with a considerable Setothosea asigna infestation, providing a comprehensive overview of the pest's impact. The study establishes five sample points diagonally, each comprising five randomly chosen plants, totaling 25 samples per site, ensuring diverse representation. The predominant larval parasitoids exhibit noteworthy efficacy, primarily from the Hymenoptera order, Braconidae family, Genus Apanteles, and Spinaria. Among the 110 larvae observed, five were parasitized, resulting in the emergence of 65 parasitoids. The parasitization rate varies from 0 - 9.09%, with prominent contributions from Apanteles sp. and Spinaria sp., belonging to the endoparasitoid type. This research significantly contributes to sustainable agriculture practices and the palm oil industry, offering insights into targeted pest control for Setothosea asigna. Despite its focus on Dharmasraya, the study provides a valuable foundation for broader applications and invites further research for generalization.
