Abstract

Salak has the scientific name Salacca zalacca including a low-growing family of palms. This seasonal fruit plant is a type of horticulture that has the potentioal to become an axport commodity in Indonesia. In East Java, especially in Lumajang, Madura and Kediri are areas that produce salak commodities. Morphological identification aims to obtain basic traits so that the appearance or phenotype of each accession can be distinguished quickly and easily, by estimating how much genetic diversity it has. This study aims to determine the morphological characters and to determine the salak kinship of Lumajang, Kediri and Madura. The result of phylogeny analysis of the Salacca zalacca kinship in East Java show that the results of the kinship analysis of the salak in the Lumajang, Kediri and Madura areas formed 2 large groups or cluster. So it can be concluded that the Salacca zalacca originating from the Lumajang, Kediri and Madura areas still come from the same ancestor. This can be seen from the value of kinship distance, the morphological identificaion equation. In addition, environmental factors can also affect the morphology of plants. Sunlight intensity, N and P nutrients can also affect the difference in leaf color

Abstract

Blast disease is an important disease that affects many rice plants. Blasts can damage rice leaves (leaf blasts), nodes (node blasts), neck blasts, colar blasts and rice grains. Symptoms on the leaves are rhombic-shaped spots with a tapered tip. The center of the patch is gray surrounded by brown to reddish brown on the edge of the spot. The color of the spots at the beginning of the symptoms is white or gray, surrounded by green-brown. Based on market demand, agricultural products that are safe and healthy for consumers as well as environmentally friendly are increasing, therefore controlling plant pathogens by using antagonistic microorganisms is one of the ways that must be considered. A number of microbes have been widely tested and are quite effective in controlling plant pathogens. PGPR and Streptomyces are biological agents that are able to reduce the level of attack of plant diseases, especially in rice blast disease. This study used a comparative method between rice cultivation and biological agent applications and rice cultivation without biological agents or control plant applications. The results obtained indicate that the application of biological agents can reduce the percentage of disease severity, reduce the percentage of infected leaves, the biological agents are also able to extend the incubation period, increase plant height growth, number of tillers and also the number of grains per panicle.

Abstract

This study aims to determine the ability of two endophytic fungi in Gondang Manis jamaican apple to inhibit the development of indigenous pathogenic fungi on these plants. The isolates of Trichoderma sp and Metarhizium sp were obtained from the exploration of endophytic fungi on the tissue of the Gondang Manis jamaican apple plant, while Fusarium sp was the result of exploration on the rhizosphere soil of the plant. Tests were carried out in vitro with a dual culture method using a completely randomized design (CRD) with FT (Fusarium - Trichoderma) and FM (Fusarium - Metarhizium) treatments, each with 5 replications. Determination of the resistance level based on PIRG and Bell Rating. Analysis using ANOVA p (˂0.05) and LSD test (p˃ 0.05). The results showed that Trichoderma sp has a high inhibiting ability (PIRG = 70%; Bell Rating = 2) against Fusarium sp, while Metarhizium sp is considered low (PIRG = 20.5%; Bell rating = 4). This shows that Trichoderma sp. Isolate has a better ability than Metarhizium sp in inhibiting the development of Fusarium sp. The mechanism of inhibition of the pathogen Fusarium sp by Trichoderma sp is to seize nutrients from pathogens Key word : Inhibition, Fusarium sp, Metarhizium sp, Trichoderma sp.

Abstract

Nitrogen is a macro nutrient needed by plants. Generally, people use inorganic fertilizers to fulfill nitrogen nutrients in plants. The problem then is, the continuous use of synthetic nitrogen fertilizers has a direct negative impact on the soil and a derivative impact on human health. The use of microorganisms, in this case bacteria, to provide nitrogen to plants can be done by isolating it and making it a biological fertilizer agent. Nitrogen fixing bacteria was isolated on the land of the oil palm plantation of PT Astra Agro Lestari. The isolated nitrogen-fixing bacteria were then tested quantitatively for their ability to fix nitrogen. The bacteria with the highest nitrogen fixing ability were then identified by sequencing their DNA nucleotide bases so that the bacterial strains were identified. The result is that there are 13 bacteria that are able to fix nitrogen with the codes J1, J3, Q5, L1, L11, J31, D1, M6, M5, R1, P2, J4 and C7. The quantitative test shows that bacteria with code D1 are the best at fixing nitrogen in the form of NH4, namely 0.27 ppm. The results of D1 bacterial DNA nucleotide base sequencing showed that the putitive Bacillus aerius strain 24K with identical values ​​and query cover reach

Abstract

ABSTRACT This study aims to determine the effectiveness of the inoculation of antagonistic biological agents in controlling stem rot disease caused by the pathogenic fungus Fusarium spp., and to increase the growth of fig stem cuttings (Ficus carica L.). This research was conducted at the Greenhouse of the Faculty of Agriculture, Islamic University of Batik Surakarta (UIBS), from September 2020 to December 2020. This study used a completely randomized design (CRD)., with 6 types of treatment, consisting of control, Trichoderma, Gliocladium, Corynebacterium, PGPR, and synthetic fungicide Mancozeb as a comparison, with 3 repetitions and 3 sub-repetitions. Observations consisted of several parameters, namely: disease incubation period, disease incidence, disease severity, shoot growth period, shoot height, leaf number, leaf area, root length, and number of roots. The results showed that Trichoderma treatment gave the best results for all observed parameters, even better than Mancozeb which is usually used by farmers. This is because Trichoderma has the ability of antagonistic in the form of very aggressive competition, producing antibiotic, and mycoparasitic mechanism against the pathogenic fungus Fusarium spp., so its utilization can be applied in organic farming to control stem rot disease which is more environmentally friendly. Trichoderma can also be used as biofertilizer because it has the ability as a good biodecomposer, its can breakdown nitrogen nutrients, dissolve phosphate, and provide micro nutrients, and even release the hormones auxin, cytokinins and ethylene, so that its effectiveness can stimulate and increase vegetative growth of fig plants in the form of shoots, leaves and roots. Keywords: fig, Fusarium spp., biological agent, Trichoderma, Mancozeb

Abstract

Proses pengolahan biji kakao sangat menentukan mutu biji kakao kering yang dihasilkan. Proses fermentasi mempunyai peran yang sangat penting dalam pengolahan biji kakao yaitu pembentukan cita rasa dan aroma biji kakao yang dihasilkan. Tujuan dari penelitian ini adalah memberikan gambaran fermentasi yang ideal dan mencari wadah fermentasi yang bisa digunakan dalam skala produksi kecil dan sederhana. Penelitian ini dilakukan dengan melakukan fermentasi menggunakan dua ukuran wadah yang berbeda, yaitu kotak kayu besar dan kotak kayu kecil. Biji kakao difermentasi selama 3 hari (3x24 jam) dengan pembalikan dan pemantauan suhu setiap hari. Biji kakao hasil fermentasi dikeringkan dengan cara sun drying dan pengeringan mekanis (cocoa dryer) selama ±7 hari. Hasil penelitian menunjukkan fermentasi dengan kotak kayu besar mempunyai efektifitas lebih baik dibandingkan kotak kayu kecil. Biji kakao yang dihasilkan dari fermentasi kotak kayu kecil juga dapat terfermentasi dengan baik sehingga kotak kayu kecil dapat digunakan sebagai alternatif untuk petani yang mempunyai hasil produksi tidak banyak.

Abstract

The sustainability of rice or food crop farming depends on the level of welfare of the farmers. One approach to measuring the purchasing power of farmers in rural areas is the Farmer Exchange Rate (NTP). The purpose of this study was to determine the development of the achievement level of the Exchange Rate of food crop farmers in Bangka Belitung from 2013-2020 with the method of analysis using quantitative descriptive methods. The results showed that the average farmer exchange rate from 2013-2020 was 93.98 percent, still below the index value of 100, which means that food crop farmers in Kepulauan Bangka Belitung Province are still not prosperous.
