Abstract

Oil palm is a favorite crop in Indonesia, because it provides good prospects in the future. Ouality oil palm seedlings are needed for oil palm development. This study aims to see the effect of various doses of Azolla pinanta fertilizer, as well as the best mixing of latosol soil and husk charcoal planting media for the growth of oil palm seedlings in the pre-nursery. The research was conducted at KP-2 Kalikuning, Maguwoharjo, Sleman Regency, Depok District, Yogyakarta Special Region Province which is located at altitude of 118 meters above sea level the research was conducted from Mei to June 024. The experimental design used was a factorial complete ramdomized design, as the first factor was the doses of azolla fertilizer consisting of 3 levels, namely D0= 0 grams/plants, D1= 10 gram/plant, and D2= 25 gram/plant. The second factor is the composition of latosol planting media: Husk charcoal which consists if 4 levels, namely V0= 100 Latosol, V1= 50%;50%, V2= 75%:25% and V3= 100% husk charcoal. 3x4x4=48 plants were needed. Observation data were analyzed by Analusis of Variance (ANOVA) at 5% real level. If there s a significant effect, it is continued with the DMRT (Duncan’t Mutliple Range Test) test at a real level of 5%. The result showed that there was no significant interaction between the dose if Azolla fertilizer and the composition of latosol planting media and husk charcoal on the growth of oil palm seedlings is PN. For planting medi Of oil plam seedling in the Pre Nursery, soil alone without husk charcoal and without Azolla fertilizer, the growth was the same as those added with husk charcoal and Azolla fertilizer

Abstract

Nutrient elements are very important for robusta coffee plants, but the availability of these nutrients in acidic soil (pH less than 5.5) or alkaline soil (pH greater than 8) is limited, as phosphorus (P) becomes bound by iron (Fe), aluminum (Al), and calcium (Ca), making it unavailable to plants. Therefore, phosphate-solubilizing bacteria are needed to convert unavailable phosphorus into available phosphorus. The purpose of this study was to identify the presence of phosphate-solubilizing bacteria in the rhizosphere of robusta coffee plants from Glagaharjo Village, Kepuharjo Village, and Umbulharjo Village, as well as to isolate and test their potential as phosphate-solubilizing bacteria. The method used in the study was an observational method presented in descriptive form. The descriptive writing includes information about the sampling location (temperature, humidity, sunlight intensity, altitude), procedures for isolating phosphate-solubilizing bacteria, macroscopic observations, microscopic observations, phosphate solubilization potential testing, catalase testing, and oxidase testing. The results of the study found 45 bacterial isolates from the three Villages. However, analysis of phosphate-solubilizing bacteria showed that only 16 isolates were suspected to be phosphate-solubilizing bacteria, potentially capable of solubilizing phosphate, as indicated by clear zones formed when cultured on Pikovskaya agar medium. Based on the characterization results, phosphate-solubilizing bacteria were found in each of the sample locations: Location 1 (Glagaharjo Village), Location 2 (Kepuharjo Village), and Location 3 (Kepuharjo Village, Cangkringan Subdistrict, Sleman Regency). The identified bacterial genera were Azotobacter and Pseudomonas, and all isolates tested positive in catalase and oxidase tests.

Abstract

ABSTRACT This research was conducted at PT. Kresna Duta Agroindo, specifically at the Pelakar Estate plantation in Sarolangun Village, Sarolangun Regency, Jambi Province, for six months, concurrent with an internship program. The study aimed to assess the impact of fertilizer application methods on the growth of oil palm seedlings of the Ramet and Dami Mas varieties in the Pelakar Estate main nursery. This study employed a completely randomized design (CRD) with two factors: variety and fertilizer application method. Two oil palm varieties were tested using two fertilizer application methods: a spoon and a practical fertilizer application tool (APP). Data from the observations were analyzed using analysis of variance (ANOVA) at a 5% significance level, and treatments that showed a significant effect were retested using Duncan's Multiple Range Test (DMRT). The analysis showed that the fertilizer application method, either using a spoon or an APP, had no effect on oil palm seedling growth parameters. Significant differences were observed in growth results between the different plant varieties. These findings indicate that the genetic factors of plant varieties have a greater influence on growth than the fertilizer application method.

Abstract

This study evaluates the effectiveness of sex pheromone traps in controlling the Yellow Rice Stem Borer (Scirpophaga incertulas). Conducted from April to July in Kesesi Subdistrict, Central Java. The research employed a Randomized Block Design applied in the experiment with two factors: trap position (in-row and jajar legowo) and height (0.5 m, 1 m, 1.5 m), resulting in six treatment combinations across 18 experimental units. Data analysis was performed using ANOVA at a 5% significance level, followed by DMRT for significant results. The highest average capture of moths occurred at 31 days after planting in the treatment in Jajar Legowo position with a height of 0.5 meters with 17 heads. At 70 days after planting, the highest attack rate was 2.36%. Pheromone traps provide effective results in controlling Scirpophaga incertulas.

Abstract

Cowpea (Vigna unguiculata L.) is one of the food crops with relatively high protein content, but its production remains relatively low. The applied cultivation technology is still not optimal, resulting in no significant increase in cowpea production. This study aims to determine the effect of applying various concentrations of Plant Growth Promoting Rhizobacteria (PGPR) on the growth and production of cowpea. The research was conducted at the Jember State Polytechnic field from July 2024 to October 2024. The study used a Non-Factorial Randomized Block Design (RBD) with 6 treatments and 4 replications. The treatments consisted of PGPR concentrations of 0 ml/L, 18 ml/L, 29 ml/L, 40 ml/L, and 51 ml/L. The observed variables included plant height, stem diameter, number of sample pods, fresh weight of sample pods, fresh weight of pods per plot, dry weight of sample pods, dry weight of pods per plot, dry seed weight per plot, and weight of 100 seeds per plot. The results showed that the PGPR treatment at a concentration of 51 ml/L significantly affected plant height, dry seed weight of samples, and weight of 100 seeds per plot. This is likely due to the role of PGPR as a biofertilizer and biostimulant. However, there were no significant differences in stem diameter, number of sample pods, fresh weight of sample pods, fresh weight of pods per plot, dry weight of sample pods, dry weight of pods per plot, and dry seed weight per plot.

Abstract

Oil palm nursery is generally conducted through a two-stage system, namely the pre-nursery stage and the main nursery stage. In the pre-nursery stage, seedlings require watering of 0.1–0.3 liters per day with a watering frequency of twice daily, in the morning and evening. Meanwhile, shading serves to protect against high sunlight intensity. This study aims to investigate the effect of light intensity and watering frequency on the growth of oil palm seedlings in the pre-nursery stage. The study was conducted from June 2024 to September 2024. It employed a factorial experiment method arranged in a split-plot design with two factors. The first factor (main plot) was light intensity, consisting of three levels: 3,500, 2,000, and 1,000 foot candles. The second factor (subplot) was watering frequency, consisting of three levels: twice a day, once a day, and once every two days with a water volume of 200 ml/day. Each treatment was replicated four times. Data were analyzed using analysis of variance (ANOVA), and if significant differences were found, the Duncan Multiple Range Test (DMRT) was applied. The ANOVA results showed a significant interaction between light intensity and watering frequency on the growth of oil palm seedlings in the pre-nursery stage, specifically in the parameter of seedling fresh weight. Light intensities of 1,000 and 2,000 foot candles resulted in taller seedlings compared to 3,500 foot candles, while a light intensity of 3,500 foot candles influenced root growth. Watering frequencies of twice a day and once a day showed better seedling growth compared to watering once every two days.

Abstract

Ratun is a rice cultivation technique, which is a rice plant that grows from the leftovers cut from rice clumps after harvesting with the aim of saving rice field management in rice cultivation. Arthropods are animals with a body characterized by a spineless and segmented body, body parts consisting of the head, chest, and abdomen which are completely wrapped by chitin and the exoskeleton. This study aims to determine the diversity of arthropods in ratun rice plants. The research was carried out in April - June 2023, and is located in Argodadi Village, Sedayu District, Bantul Regency, Special Region of Yogyakarta. The sample collection in this study was divided into several ways, namely pit fall, networking, yellow traps, and direct observation per clump. The formula used to calculate the arthropod diversity index is Shannon-Wiener and Gini-Simpson. The results of the analysis of the arthropod diversity index showed that the ratun rice had moderate diversity based on the Shannon-Wiener index, while the Gini-Simpson index showed a fairly high level of diversity

Abstract

This research was conducted at PT. Sawit Sejahtera, South Sumatra Province, from February to April 2024. This study aimed to assess and test the effectiveness of castration tools by comparing 8 cm dodos with modified bamboo tools for castration on immature oil palm plants. This study used a survey method to describe the research location and collect primary data. The research was conducted in Block E-01, which has a hilly area. Each tool was tested on 150 sample trees located on 10 different terraces. The data observed included worker output, work quality, and safety risks. Data were analyzed using an independent t-test. The results showed that the use of the modified bamboo tool for castration was generally more effective as it produced 15.71% higher worker output compared to the dodos tool. Work quality was also better with the bamboo tool, as no fronds were damaged in the sample trees, while 126 trees or 84% of the sample trees were damaged due to the dodos tool. However, in terms of safety, no accidents were reported from using either tool. Nonetheless, the tool's effectiveness comes with the note that castration must be performed monthly.

Abstract

The objective of the study was to identify the responses of oil palm seedlings to drought stress conditions during pre-nursery cultivation. The research was conducted at two locations: the Maguwoharjo Educational and Research Field (Kebun Pendidikan dan Penelitian/KP2) and the Central Laboratory of the STIPER Yogyakarta Institute of Agriculture. The research was carried out from April to July 2021. A factorial experimental design with two factors arranged in a completely randomized design (CRD) was used in this study. The first factor consisted of three hybrid oil palm varieties: D×P SAIN-2 (V1), D×P SAIN-3 (V2), D×P SAIN-4 (V3). The second factor was the irrigation frequency or drought stress level, with three levels: watering once a day (F1), watering every 2 days (F2), and watering every 3 days (F3). The research data were analyzed using analysis of variance (ANOVA) at significant level of 5%. In the event of significant differences being identified among the treatments, further testing was conducted using Duncan's Multiple Range Test (DMRT) at a 5% significance level. The result showed that there was no significant interaction between different varieties and irrigation frequencies on oil palm seedling growth in the pre-nursery stage. However, the variety D×P SAIN-4 exhibited significant effect on stem diameter, leaf number, leaf area, and fresh stem weight. Under drought stress conditions, the best growth performance was observed in oil palm seedlings of the D×P SAIN-4, followed by the D×P SAIN-2. Additionally, irrigation frequency influenced stem diameter and leaf number. Overall, oil palm seedlings in the pre-nursery stage showed the best growth when watered once a day. In the pre-nursery cultivation stage, all oil palm seed varieties can tolerate watering every 2 (two) days
