Abstract

Coffee is a plantation commodity that is on the rise in line with the increasing demand for coffee both domestically and abroad. The quality of Arabica coffee is greatly affected by the management of cultivation techniques and altitude. Pejawaran District is an area that has developed Arabica coffee, however, plant management is not optimal so that productivity is low. This research was conducted in Sarwodadi Village, Pejawaran District, Banjarnegara Regency from July to September 2019. Data collection was carried out by survey method at 4 locations with different altitudes namely 800, 1.000, 1.250 and 1.400 m asl. The samples were taken by 10 percent from total population of population . The observation variables included plant height, number of beans per bag, yield of dry coffee beans per plant, weight per seed, density of stomata, width of stomatal opening and leaf chlorophyll content. The cultivation performance in Sarwodadi Village was very diverse and was not in accordance with good coffee cultivation, the farmers only take the results without carrying out optimal care as recommended. The highest seed yields were achieved at 1.250 m asl of 6,04 kg / plant, as well as the physiological characters which included stomata density 191,68 units/mm2 and stomata opening width of 3,28 µm. Key words: arabica, coffee, cultivation, high land

Abstract

Micro, Small and Medium Enterprises are a form of productive economic business carried out by individuals or individual business entities that meet the criteria for Micro, Small and Medium Enterprises (MSMEs). MSMEs have an important role in the regional local economy (Sriya, 2010). This is indicated by the ability of MSMEs to drive regional economic activities and provide employment opportunities. The existence of MSMEs in Mandiraja District has not been followed by good data management. With so much information, the Mandiraja district office has not yet fully provided complete information, many people do not know the location of the existence of MSMEs causing a lack of improvement in surrounding businesses. So it is necessary to organize data that is integrated with Geographic Information Systems in order to make it easier to read information related to MSMEs in Mandiraja District, Banjarnegara Regency. The purpose of this research is to build a Geographic Information System for Agro-industry MSMEs in Mandiraja District, Banjarnegara Regency.

Abstract

Moringa plants have many compounds that can be used as medicine or used to stimulate plant growth. Moringa plants contain growth hormones, namely cytokinins and zeatin. The utilized Moringa leaves as a natural or organic growth regulator that can be affect plant growth. This study aims to determine the use of Moringa leaves as a natural ZPT and the length of soaking for the growth of sugarcane bud sets for researchers themselves or those who read this research report. The research was conducted at the LPP Polytechnic Practice Garden, Wedomartani Village, Sleman Regency, Yogyakarta from January to June 2020 (7 months). Experiments were arranged in a factorial randomized block design (RBD). The first factor was giving the concentration of Moringa leaf extract which consisted of 4 treatments, namely: without giving Moringa leaf extract (K0), 10% (K1), 20% (K2), and 30% Moringa leaf extract (K3). The second factor is the immersion time of Moringa leaf extract which consists of 4 treatments, namely: without soaking Moringa leaf extract (R0), 10 minutes (R1), 20 minutes (R2), and 30 minutes (R3). There were 16 treatment combinations and was repeated 3 times so that there were 48 experimental units. Each experimental unit consisted of 2 plants so that there were 96 plants in total. The results showed that there was no interaction between the concentration of Moringa leaf extract treatment and the duration of soaking. Giving the concentration of Moringa leaf extract and the duration of soaking did not occur any interaction between the two treatments and had a single significant effect, namely the concentration on several variables, namely plant height, stem diameter, wet weight and dry weight. Giving the concentration of Moringa leaf extract as much as 20% produced plant height, stem diameter, number of leaves with wet weight and dry weight were higher than without giving moringa leaf extract.

Abstract

Organic matter plays a role in forming structures, improving aggregate stability and increasing soil water availability. This study aims to determine the response of the soil to the application of two types of organic matter by observing the physical properties of the soil such as bulk density, aggregate stability, meso pores, micro pores, and available water. The research was conducted at Agricultural Training, Research and Development Station Gadjah Mada University Yogyakarta. The strip-split-plot design in an Randomized Complete Block layout with three factors was used to this experimental. The first factor was two types of organic matters, namely cow manure and press mud. The second factor was dose of organic matter, namely control, 1 t.ha‑1, 2 t.ha-1, and 3 t.ha‑1. The third factor was two inbreed lines of paddy which adaptive to dry-land condition, namely line 11 and line 12. The results showed that organic matter had a significant effect on aggregate stability and meso pores, but did not significantly influence bulk density, micro pores, and available water. The aggregate stability was higher and meso pores was smaller while bulk density and available water was lower with press mud.

Abstract

Azolla is an organic material wealthy in nutrients, particularly nitrogen, required for lowland rice. The employment of Azolla as fertiliser for rice doesn’t ought to be costly and might even suppress weed growth. This study aimed to see the most effective application of Azolla to rice growth. The analysis technique used was a Randomized Block Style Design (RAKL) with a pair of treatments being tried. The treatment of 1 dose of Azolla consisted of a dose of Azolla 0 (A1), Azolla 30 g/bucket (A2) and a dose of Azolla 45 g/bucket. (A3). Treatment 2 was immersion consisting of immersion (B1) and no immersion (B2). Azolla was applied 2 times, half the dose 1 week before planting and 10 days after planting. Every treatment was recurrent 5 times thus there were 30 experimental treatments. The data were analyzed using the F test, if it was significantly different, it was followed by Duncan's test (DMRT) at a 5% level. The result of this research is that Azolla dose treatment and immersion have not been able to increase plant height and the number of tillers

Abstract

Weeds are plants whose presence is not desired in the planting area because they are considered detrimental, inhibiting plant growth and production. The losses caused by the presence of weeds in cultivated areas can be very large, but these losses are rarely measured because weeds and cultivated plants are both plants (plants). Chemist weed control is widely used because the effects are seen more quickly and in an easier way. There can also be competition between weeds because of the allelopathy that can suppress the growth of fellow weeds and/or cultivated plants. Allelopathy is one of the ingredients that can be used as a herbicide biological material. Ageratum conyzoides contains chemical compounds from the class of alkaloids, anthraquinones, terpenes, steroids, tannins and phenols that can inhibit cell division germination, and inhibit the growth and/or development of weeds/other plants. This study aimed to determine the efficacy of Ageratum conyzoides extract used as a biological herbicide and obtain a concentration of Ageratum conyzoides extract which could be used as a biological herbicide. The experiment was carried out at the Krajan Practice Gardens, Polytechnic LPP Yogyakarta, with treatment concentrations of extracts of Ageratum conyzoides, namely 0% (A0), 1% (A1), 3% (A2), 5% (A3) and 7% (A4) per m² sample plot. Treatment A3 (3% concentration) was the concentration that caused the greatest poisoning symptoms compared to treatments A5 (5% concentration), A7 (7%), A1 (1% concentration) and A0 (0% concentration).

Abstract

This study aims to determine the effect of administering Arbuscular Mycorrhizal Fungus (AMF) with different application times on the growth of oil palm seedlings in Pre-Nursery. The sprouts used came from PPKS with the D X P Marihat variety. This research was conducted at the Green House Polytechnic LPP Yogyakarta arranged in a factorial Randomized Block Design (RBD). The first factor was the administration of AMF with the dose used, namely M0 for no AMF, M1 with 5 grams of JMA, and M2 with 10 grams of AMF. The second factor was the time of application which consisted of 3 levels, namely: W1 (Application 5 days before planting), W2 (Application 15 days after planting), and W3 (Application 30 days after planting). From these two factors, 9 treatment combinations were obtained which were repeated 3 times, so that they consisted of 27 experimental units. The treatments were planted in polybags measuring 20 X 20 cm. Each experimental unit consisted of 2 plants, so a total of 54 oil palm seeds were needed. The variables observed were plant height, stem diameter, number of leaves, plant wet weight, and plant dry weight. Analysis of the data using variance (ANOVA) with a significant 5%, if there is a significant difference followed by Duncan's further test (DMRT). The results showed that there was no real interaction between the administration of AMF and the different application times on the observed growth variables. The AMF treatment had no significant effect on plant height, several leaves, wet weight, or dry weight but had a significant effect on stem diameter. Different times of application of AMF did not significantly affect all observed variables, namely plant height, number of leaves, stem diameter, plant wet weight, and plant dry weight.

Abstract

Sugarcane (Saccharum officinarum L.) is a plantation crop that has an important role in improving the economy in Indonesia as well as the main raw material in sugar production. The single bud planting method is a nursery method that is widely used and in demand by farmers today for the production of sugarcane seeds. One of the best ways to grow seedlings is to have a good root system to get optimal nutrients. One of the efforts to support the growth and function of the roots is by giving PGPR (Plant Growth Promoting Rhizobacteria). This study aims to determine the effect of differences in PGPR concentration on the growth of sugarcane bud set seedlings. The research was carried out from April to June 2021 at the LPP Polytechnic Integrated Practice Garden, Wedomartani, Sleman, Yogyakarta. This study used a non-factorial Randomized Block Design (RAK) method on one PGPR factor with 6 different concentration treatments. Each treatment was repeated 3 times so that there were 54 experimental units. The treatments used were PGPR concentrations of 0.3 ml/polybag, 0.6 mL/polybag, 0.9 mL/polybag, 1.2 mL/polybag and 1.5 mL/polybag. The results showed that the administration of PGPR with different concentrations did not significantly affect all parameters of sugarcane seedlings from the bud set observed, namely: plant height, number of leaves, stem diameter and root length.
