Abstract

The research was carried out with the aim of finding out the effect of types compost by product in several types of soil on growth of oil palm seedlings in pre nursery which was carried out in Wedomartani Village, Sleman, Yogyakarta in December 2023-March 2024. It was prepared using factorial experimental method in a Complately randomized desaign which consist of two factors, namely the type of compost, there are 4 types of treatment (with out compost, solid, Mucuna bracteate, and empty bunches), and the type of soil there are 3 types, namely (regusol, latosol, grumosol). In the treatment with out compost (control), standard doses of NPK fertilizer were given. The results of research based on parameter data were analysed using variance at a 5% level, if the effect was real, it was further tested with DMRT at a 5%. The results showed that there was a real interaction between soil type and compost type on canopy fresh weight and leaf area. Providing solid compost, Mucuna bracteate, empty bunches and NPK fertilizer as controls gave the same effect.

Abstract

Weeds are unwanted plants because they are detrimental to the absorption of nutrients, water, carbon dioxide, light, and growing space. Chemical weed control is an effective method in large areas of oil palm plantations because it uses less labor and time. The purpose of this study was to determine the effectiveness of triclopyr herbicide and polyoxyethylene alky ether adjuvant in controlling Solanum torvum weeds. The research location was Sawita Estate plantation, South Kalimantan. This study used non-factorial experiments arranged in RAK, using several doses of triclopyr herbicide and polyoxyethylene alky ether adjuvant. This study consisted of one factor with 5 treatments, namely control (no treatment), Triclopyr 3.3 ml/l water + polyoxyethylene alkyl ether 0.7 ml/l water, Triclopyr 4.2 ml/l water + polyoxyethylene alkyl ether 0.9 ml/l water, Triclopyr 5 ml/l water + polyoxyethylene alkyl ether 1.1 ml/l water, and Triclopyr 5.8 ml/l water + polyoxyethylene alkyl ether 1.3 ml/l water. Each treatment was repeated four times. Observation of the toxicity level of weeds to herbicides was done visually with scoring based on the European Weed Research Society (EWRS). Scoring data were analyzed by ANOVA (Analysis of Variance) with a real level of 5%, and if there is a significant effect, it is continued with Duncan's Multiple Range Test (DMRT) at the 5% level. In the treatment of herbicide triklopir (5 ml/water + polyoxyethylene alkyl ether), 1.1 ml/water is effective in controlling Solanum torvum weeds; this is indicated by the results of scoring with increasingly smaller numbers, which means all weeds die. The cost used in the treatment of triclopyr (5 ml/water + polyoxyethylene alkyl ether) 1.1 ml/water is an efficient treatment compared to other treatments in controlling Solanum torvum weeds.

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

Weed control during replanting activities is an important activity. In general, weed control was done using a knapsack sprayer, but currently weed control can also be done using a drone sprayer. This research was conducted to compare the effectiveness and efficiency of weed control using knapsack sprayers and drone sprayers. This research compares the application of knapsack sprayers and drone sprayers in controlling weeds during replanting of oil palm plantations which includes the time required for the weeds to die, the duration of time required for spraying, and the costs required. The data obtained were analyzed using the independent T test. The results of the research show that using a drone sprayer to control weeds during replanting is more efficient in terms of time and cost than using a knapsack sprayer, while in terms of effectiveness in killing weeds there is no real difference between both. Drone sprayers provide a better alternative for weed control when replanting in oil palm plantations.

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

This research aims to assess the impact of rice husk charcoal and fruit eco-enzyme concentrations on the growth of oil palm seedlings during the pre-nursery stage. Conducted in Wedomartani, Ngemplak, Sleman, Yogyakarta, from May to August 2024, the study employed a factorial experiment using a Completely Randomized Design (CRD) with two factors. The first variable was rice husk charcoal with four treatment levels: no charcoal (control), ratio of husk charcoal and topsoil 1:4, ratio of husk charcoal and topsoil 1:2, and ratio of husk charcoal and topsoil 2:1. The second variable was eco-enzyme concentration at three levels: 0%, 10%, and 20%. These combinations resulted in 12 different treatments, each replicated three times, with two seedlings per replication, requiring a total of 72 polybags (2 seedlings x 3 replications x 12 treatments). Data were analyzed using ANOVA at a 5% significance level, and if significant differences were found, further testing was conducted using DMRT at the same significance level. The findings revealed no significant interaction between the use of rice husk charcoal and eco-enzyme concentrations on the growth of oil palm seedlings. The various ratios of rice husk charcoal (control, 1:4, 1:2, 2:1) had similar effects on seedling growth, and the different eco-enzyme concentrations (0%, 10%, 20%) also showed uniformly positive effects on seedling development.

Abstract

Corn is one of the food crops in Indonesia that has great potential to be developed, one of which is Waxy Corn. This type of corn has a high amylopectin content, but its productivity is still relatively low. One effort to increase the productivity of Waxy Corn is through the use of liquid organic fertilizer from tofu waste. This research was conducted on the land of the Jember State Polytechnic in July-October 2024 using a randomized block design with a single treatment, namely the comparison of the concentration of liquid organic fertilizer tofu waste. There are six treatment levels, namely control (0 ml/l), 26 ml/l, 28 ml/l, 30 ml/l, 32 ml/l, and 34 ml/l. The data were analyzed using analysis of variance, and if there was a significant difference, a further test of the smallest significant difference was carried out. The results showed that the treatment of liquid organic fertilizer with a concentration of 34 ml/l had a significant effect on the stem diameter at the age of 21 days after planting and the weight of the cob per sample. The concentration of 30 ml/l affected the cob diameter, while the concentration of 32 ml/l affected the cob weight per plot. The parameters of plant height and biomass weight did not show significant differences.
