Abstract

One of the common problems hampering the cultivation of potatoes in middle latitude is the presence of bacterium Ralstonia solanacearum commonly known to cause wilt disease, by which crop failure might be caused when serious attack occurs. The objectives of the research were to obtain the application of antagonistic microbes to inhibit the wilt disease caused by R.solanacearum and to increase the growth and yield of potato in middle latitude. The research was conducted from July to October 2012. Antagonistic microbes were used in this research to inhibit the bacterial wilt disease caused by R.solanacearum on potato planted in Bumiaji, Batu. Trichoderma viride, Streptomyces sp. and Pseudomonas fluorescens isolates were selected to be applied as treatments either singly or in combination. Randomised block design was applied on the treatment group with three replications. The results showed that the single application of Pseudomonas fluorescens or combined application of Streptomyces sp. and Trichodermaviride + Streptomycessp. was capable of extending incubation period 4 to 7 days and reducing disease incidence  44.85% - 50.09%, reducing disease intensity up to 61.23 - 72.77%, reducing the population R.solanacearum up to 7.28 - 97.88%, increasing the number of leaves and the marketable yield as much as 67.96 - 81.98%.Keywords: control, Ralstonia solanacearum, antagonistic microbes, middle latitude

Abstract

Implementing protocols in responding pandemic covid19, that are distance learning and work from home, causes an unexpected thing toward academic atmosphere in higher education. Learning process that previously done by face to face interaction is suddenly replaced by online learning. Some difficulties are not merely affected campus’ academia, but also public intellectuals who gather in an association including Indonesia’ Centre of Asian Studies (CENAS). Aside of learning, face to face discussion among lecturers as well as public intellectuals to share some new information about research result could not also be hled. In this sense, there has been a concerned issue about decreasing the spirit of knowledge and information sharing among intellectuals.  To respond the anxiety, UP2M as a research centre of the Politeknik Negeri Jakarta in collaboration with its partner, Indonesia’ Centre of Asian Studies (CENAS), hosts an online seminar or widely known as web-based seminar (webinar). All the distinguish speakers are from the Politeknik Negeri Jakarta who have been known for their eagerness in doing research. As a result, arranging this webinar has meant that readiness of all civitas academia to suit themselves with the situation of online learning that is unavoidable during the current pandemic covid-19.

Abstract

Lead (Pb) is the heavy metal that causes the most pollution in the environment. This study was conducted to compare the ability of water spinach and spinach plants to absorb lead due to the administration of various doses of ZA as a heavy metal suppressor on polluted land. This research is a pot experiment using a factorial randomized block design (RBD) with two factors. The first factor is the type of plant (Kangkung and Spinach). The second factor was the dose of ZA fertilizer  (0; 1.19; 2.38 3.57; 4.76 g / pot). The variables observed included growth, plant yield, and Pb concentration in plants. The results showed that the growth of kale plants increased with the increasing dose of ZA application up to 2.38 g / pot. Increasing the dose gave an insignificant increase in growth (P <0.05), likewise in spinach plants. However, higher doses caused a significant reduction in the number of spinach leaves (P <0.05). The fresh weight of kale roots and shoots significantly increased by an average of 50.74% and 36.57% compared to the control. While the spinach plant experienced an increase in the average root and shoot fresh weight significantly by 50.76% and 53.10% compared to the control. Water spinach plants accumulated more Pb in the crown with an average Translocation Factor (TF) value of 1.09. Meanwhile, spinach plants accumulated more Pb in their roots with an average TF value of 0.75. These results suggest that the application of ZA increases the Pb uptake of plant hyperaccumulators from vegetables. However, spinach is safer to eat because heavy metals are accumulated in the roots. Keywords: Phyitoremediation, Lead, water spinach, spinach, ZA, Translocation.

Abstract

The need for sorghum from time to time is increasing for various purposes, including for feed, food and industrial materials. On the other hand, sorghum production is still low. The development of sorghum cultivation is directed at land with low fertility levels such as Ultisol soil. Therefore, it is necessary to apply environmentally friendly cultivation technology. The purpose of this study was to explain the effect of application of various Liquid Organic Fertilizer (LOF) compositions and their concentrations on the growth and yield of sorghum. This research was conducted at the Agricultural Technology Research and Development Installation (IP2TP) Samboja, East Kalimantan starting in December 2020 until March 2021. This study used a Split Plot Design where the main plot was a type of LOF composition consisting of 5 levels and sub-plots is the concentration of LOF consisting of 3 levels with the frequency of spraying LOF 3 times in one planting period (10 days interval). The results of this study showed that the combination of various LOF compositions and their concentrations did not have a significant interaction effect on the growth and yield of sorghum plants. The best composition of  was the mixture of goat urine, amino acids and bioactivators, with plant height growth at 53 DAP of 182.81 cm, fresh weight of leaves and stems of 19558.07 grams/plot equivalent to 48.90 tons/ha and dry weight of seeds 3278.53 grams/plot. equivalent to 8.20 tons/ha dry weight of seeds.

Abstract

This study aimed to evaluate the growth and yield of two potato genotypes (S) due to three sources of nitrogen (G) fertilizer on medium plains. The study was arranged in a two-factor, randomized block design factorial and was repeated three times. The first factor is the source of N fertilizer, consisting of three levels: S1 = ZA ((NH4)2SO4), S2 = urea (CO(NH2)2), and S3 = ammonium nitrate (NH4NO3). The second factor was potato genotype, consisting of two levels G1 = MS 13 genotype and G2 = At 4 genotype. The data obtained were analyzed by F test at 5% level (ANOVA) to determine the effect of treatment and further LSD test was carried out to determine differences between treatments, and multiple regression analysis to determine the most influential factors on potato tuber starch content. The results showed that the highest starch content was obtained by the At 4 genotype of 18,50% and was suitable for medium plains. While the starch content of the MS 13 genotype was 17,53%. For fertilizing nitrogen sources, it is recommended to use ammonium nitrate, because it obtains the highest yield of 27,30 tons ha-1 from other nitrogen fertilizer sources.

Abstract

Land contaminated with heavy metals and toxic substances is an environmental problem that must be addressed immediately. Heavy metals in the soil affect plant growth, productivity and ultimately lead to human health.The amount of heavy metals present in plants is influenced by their concentration in the soil, the physical-chemical conditions of the soil, the species and plant genotypes involved. The study aimed to obtain Croton (Codiaeum variegatum L.) cultivars that were tolerant of lead (Pb) heavy metal stress, studying the phytoremediation strategy of croton cultivars (Codiaeum variegatum L.) in absorbing heavy metal lead (Pb) from the soil. The study was conducted at the Greenhouse of the Faculty of Agriculture, Islamic University of Malang, from August to November 2018. The results showed that the growth in number of leaves and plant height showed no significant effect, while the total root length and leaf area of each cultivar were significant. Cultivar that hastolerance of lead (Pb) heavy metal stress is Jago cultivar, indicated by high Pb concentrations found at the roots of 0.48060 ppm, and also has the largest total root length of 5748.817 cm. The calculation results obtained TF values <1 and BCF> 1, so the phytoremediation strategies of croton cultivars exposed by Pb from the soil include to phytostabilization.
