Abstract

Oil palm productivity is influenced by the availability of quality seeds. One important factor includes making seeds or nurseries. Single stage and double stage are two categories included in the provision of seeds based on type. To evaluate the frequency and severity of disease attacks, this study aims to identify various diseases that attack oil palms in pre nursery and main nursery. From July to August 2024, research was conducted at the Bangun Bandar plantation, North Sumatra Province, in an oil palm nursery area managed by PT. Socfindo. Purposive sampling was used as a survey method. Abiotic diseases (stunted, curly, grass like leaves, curly, and not planted properly) and biotic diseases (leaf spots) are often found in prenurseries. On the other hand, abiotic diseases (stunt, wrinkled leaves, curled leaves, twisted leaves, incompletely opened leaves, twisted leaves and misplanting), biotic diseases (leaf spots) are also often found in the main nursery. In the pre-nursery, leaf spot was the largest percentage of disease attacks (25.50%), but in the main nursery it was 28.55%. At pre nursery, leaf spot disease (9.50%) and the main nursery (11.50%) had the highest level of disease attack severity, both of which were classified as light damage.

Abstract

ABSTRACT This research examines the potential of oil palm leaves as raw material for compost, carried out in Bandar Pasir Mandoge Village, North Sumatra, from March to May 2023, using a Completely Randomized Design (CRD) with two main factors: compost material and type of decomposer. The compost material consists of tankos, leaves, and a mixture of tankos+leaves, while the decomposer consists of decomposers D1, D2, and D3. The parameters measured include C/N ratio, weight loss, compost color, compost odor, compost pH value, compost temperature, compost humidity, and compost friability. The research results showed significant variations in C/N ratio values ​​for organic materials, with values ​​ranging from 12 to 38. Compost material from leaves with D1 decomposer achieved the lowest C/N ratio value, while tankos compost with D1 decomposer had the highest value. Decomposer D2 is more effective in speeding up the decomposition process compared to D1 and D3. The fastest compost shrinkage occurred in the treatment with D3 decomposer, while the longest shrinkage occurred in the treatment with D1 decomposer. This research supports the principles of sustainable agriculture by utilizing high fiber organic waste and reducing environmental pollution. Tankos organic material decomposes the fastest, and the D2 decomposer is more effective than other decomposers. There is a real interaction between organic materials and decomposers on compost quality. Keywords: Tankos, leaves, compost, decomposer

Abstract

The purpose of this study is to ascertain the impact of the combination between the dosage of P fertilizer and the inoculum dose of Rhizobium sp. on M. bracteata plants' root nodule growth and creation, the effect of P fertilizer doses on M. bracteata plants' root nodule growth and creation and the effect of Rhizobium sp. inoculum doses, on M. bracteata plants' root nodule growth and creation. This research was carried out at KP2 of the STIPER Agricultural Institute which is located in Wedomartani Village, Depok District, Sleman Regency, DIY, with an altitude of 118 meters above sea level, from January to June 2024. This research was carried out using a two-factor experimental method prepared in RAL. The first factor is the dose of P fertilizer (TSP) consisting of 4 dose levels, namely: 0 g/polybag, 1 g/polybag, 2 g/polybag, and 3 g/polybag. The second factor is the dose of Rhizobium sp. inoculum which consists of 4 dosage levels, namely: 0 g/polybag, 5 g/polybag, 10 g/polybag, 15 g/polybag. These two variables were used to create 4 x 4 = 16 treatment combinations. Each treatment was then repeated four times, resulting in 16 x 4 = 64 experimental plants in terms of seeds. Analysis of variance (ANOVA) was used to assess the research data at the 5% significant level. The treatment that had a real effect in the DMRT follow-up test was at the 5% significant level. The results of the research showed that there was a real interaction between the treatment combination of P fertilizer dose and Rhizobium sp. inoculum dose on the parameters of fresh root weight, root length, number of ineffective root nodules, shoot dry weight and root dry weight. The combination of P fertilizer dose of 1 g/plant and Rhizobium inoculum 5 g/plant produces the best fresh root weight, the combination of P fertilizer dose of 0 g/plant and Rhizobium inoculum 10 g/plant produces the best root length, the combination of P fertilizer dose of 0 g/plant and Rhizobium inoculum 15 g/plant produced the least number of ineffective root nodules, the combination of P fertilizer dose 1 g/plant and Rhizobium inoculum 5 g/plant produced the best shoot dry weight, the combination dose of P fertilizer 1 g/plant and Rhizobium inoculum 5 g/ plants produce the best root dry weight. Providing P fertilizer doses of 0, 1, 2, and 3 g/plant had the same effect on the growth and formation of root nodules of M. bracteata plants. Giving Rhizobium sp. inoculum doses of 0, 5, 10, and 15 g/plant had the similar impact on M. bracteata plant development and nodule production.

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

Sinogo farmers, starting in November 2022 have cultivated Vanilla plants (Vanilla planifolia Andrews) in a greenhouse using planting medium in the form of mixture of soil, manure and cocofiber in a ratio of 1 : 1 : 1. The use of cocofiber causes the planting medium to dry out quickly. In 2023, Sinogo farmers had problem of limited water for watering because the water used comes from springs, which are very small during the dry season. The aim of the community service activity was to provide information about water-saving drip irrigation technology and to apply drip irrigation techniques to vanilla cultivation in greenhouses. Community service begins with survey activities to determine regional conditions and the level of farmers' understanding of drip irrigation technology. The next stage was education and practice of drip irrigation technology. Evaluation monitoring was carried out to determine the results of drip irrigation practices. The survey results showed that 87% of farmer group members did not know about drip irrigation techniques and they were very interested in implementing this technology. As many as 100% of respondents expressed interest in implementing drip irrigation technology on vanilla plants. After providing service to the Sinogo farmer community, they understood the drip irrigation technique, which was a water-saving irrigation technique. The results of the community service implementation showed that drip irrigation was running but was still limited because little water was stored due to low rainfall until December 2023. The conclusion was that most members of farmer community did not understand drip irrigation techniques. The success of drip irrigation techniques was influenced by the availability of water sources.
