Abstract

Feed safety becoming the main factor to produce good quality food. The purpose of this study was to evaluate the ability of lactic acid bacteria in degrading aflatoxin B1, suppressing the growth of contaminant bacteria, and its application on feed. Biological degradation of aflatoxin B1 (AFB1) in liquid cultures and Escherichia coli and Saccharomyces aureus inhibition by Lactobacillus plantarum were examined. Fermentation of corn for 24 hours by L. plantarum was used to determine the ability of LAB to decrease E. coli, coliform, mold, and AFB1 on a solid substrate. This study showed that both L. plantarum TSD-10 and DR-162 could inhibit E. coli growth at 3% and 5% supernatant addition. The addition of 5% L. plantarum DR-162 and TSD-10 could inhibit S. aureus at 97.40% and 97.28%, respectively. Furthermore, viable cells of L. plantarum DR-162 and TSD-10 removed 56.97% and 64.65% AFB1 within 72 h of incubation, respectively. The AFB1 reduction by nonviable cell was lower than the viable cell. The population of E. coli, coliform, and mold completely disappeared in both fermentation treatment of corn by L. plantarum DR-162 and TSD-10 at 3% and 5%. AFB1 significantly decreased by 17.57% and 22.60% on 5% L. plantarum DR-162 and TSD-10 treatment.

Abstract

Chromium is a heavy metal that is toxic, bioaccumulative, persistent, and cannot be decomposed in the environment. The Cr6+ ion is a chromium ion that has the highest toxicity among other chromium ions, so its presence in the environment is hazardous for plants, animals, and humans. Sulfur is an essential element for plants, whose presence can reduce Cr6+ concentrations in the terrestrial environment by inhibiting the uptake of Cr6+ by plants. Tagetes erecta is a bioremediation agent plant that can remediate land polluted with Cr6+ waste. In this research, we studied the growth of T. erecta in media polluted with Cr6+ and sulfate and its ability to accumulate of Cr6+. Several parameters observe in this experiment, i.e. growth parameters, namely plant height, number of leaves, number of flowers measured at the end of the study, dry weight, root length, and Cr6+ concentration estimated using the diphenylcarbasid method. The results showed that the plant height of T. erecta. was not significantly different, and sulfate addition did not affect plant height. The addition of sulfate affected the number of leaves and flowers, dry weight of root shoots, root length, and Cr6+ content in T. erecta. polluted with Cr6+. so that in these parameters, there was a significant difference in the addition of Cr6+ and sulfate on growth of T. erecta and its ability to Cr accumulation.

Abstract

The development of grapes (Vitis vinifera) has obstacle among others are limited optimal land and difficult nurseries. Suboptimal land use for grape cuttings can use red yellow podzolic soil (ultisol). Podzolic soil has an acidic pH and low macro and micro nutrient uptake but can still be used as a growing medium. Vierul local grapes are a type of grape that has begun to be developed as root stock in nurseries but needs to be improved for its root success using a synthetic phytohormones bath of napthaline acetic acid (NAA). The purpose of this study was to determine the morphological character of vierul local grape cuttings at various concentrations of NAAsoaking in podzolic soil growing medium. This research has been carried out in a screen house from August to December 2021. This study used a non-factorial completely randomized design (CRD) with 3 treatments and 3 replications as block consisting of F0, F1, F2, F4 following by 0, 2, 4, 6 g L-1 respectively. The morphological characteristics observed is number of bud break, time of leaves appear, number of leaves, tendril length and percentage of live cuttings. The results of the study were analyzed using ANOVA at the 5% level and continued using the DMRT at the 5% level. The result showed that soaking of NAA at a concentration of 0 g L-1 (F0) had the best result for the variable number of bud break and number of leaves. Concentration of 6 g L-1 (F3) had the best result for variable length of the tendril while for the variable when the leaves appear, NAA soaking has no significant effect. The percentage of live cuttings is still low because it is influenced by the quality (material) of cuttings, the age of woodstock, growing media and water availability.

Abstract

Permintaan pasar terkait kentang sangat tinggi mengakibatkan lahan budidaya semakin meningkat. Hal ini beresiko bagi keseimbangan lingkungan karena dapat menyebabkan bencana alam. Oleh karena itu, diperlukan inovasi budidaya kentang di lahan medium. Lahan medium merupakan daerah dengan elevasi (ketinggian) 300-700 mdpl. Budidaya di lahan medium akan menyebabkan hasil yang diperoleh tidak dapat maksimal jika dibandingkan dengan hasil budidaya kentang di dataran tinggi serta tanaman akan rentan penyakit. Peran mikroorganisme yang terkandung dalam PGPR dan Tricho Powder diperlukan untuk memperoleh hasil yang maksimum serta membantu menekan intensitas penyakit. Penelitian ini bertujuan untuk mengetahui pengaruh perbedaan konsentrasi PGPR komersial dalam meningkatkan hasil panen budidaya kentang, mengetahui pengaruh perbedaan konsentrasi Tricho Powder dalam menekan intensitas serangan penyakit, dan mengetahui salah satu jenis kandungan dalam PGPR. Penelitian ini dilakukan dengan Rancangan Acak Lengkap (RAL yang terdiri dari 6 perlakuan dengan 4 ulangan. Perlakuan dalam penelitian ini meliputi P0 (Kebiasaan Petani), P1 (PGPR 20mL), P2 (PGPR 40 mL), P3 (Tricho Powder 80gram/10Liter), P4 (Tricho Powder 150gram/10L), dan P5 (PGPR 20mL+Tricho Powder 80gr/10L). Data yang diperoleh kemudian dianalisis dengan ANOVA apabila terdapat signifikasi kemudian dilanjutkan dengan uji lanjutan yang ditentukan berdasarkan nilai KK (Koefisien Keragaman) yang di peroleh. Hasil penelitian menunjukkan bahwa,perbedaan konsentrasi PGPR komersial memberikan pengaruh positif terhadap hasil panen kentang dengan perlakuan kombinasi PGPR 20mL/10L+Tricho Powder 80 gr/10L (P5) merupakan perlakuan terbaik menghasilkan rerata tertinggi pada setiap parameter. Selain itu pada perlakuan yang sama, intensitas penyakit berhasil ditekan sebesar 37.55% dibandingkan dengan perlakuan kontrol. Berdasarkan kemampuanya dalam menghasilkan IAA (Indol Acetic Acid) dari 5 isolat yang diperoleh hanya 1 isolat (IS 5) yang menunjukkan hasil positif dan dilanjutkan ke uji molekuler.Genus Bacillus teridentifikasi sebagai salah satu jenis kandungan dalam PGPR dan memiliki kekerabatan terdekat dengan spesies Bacillus velezensis.

Abstract

Weed interference results in increased synthesis of reactive oxygen species (ROS). High accumulation of ROS causes oxidative stress and stimulates the activation of the antioxidant defense system in plants. Weed interference causes biotic stress in the form of allelochemicals and abiotic stress in the form of competition for plants which results in the inhibition of growth and development in plants. Ageratum conyzoides is an annual weed in plantations and can cause biotic and abiotic stress on surrounding plants. This study aims to determine the effect of A. conyzoides interference on antioxidant content in the form of total phenol and total proline in patchouli leaves [Pogostemon cablin (Blanco) Benth cv. Sidikalang] as well as the percentage of essential oil yield from P. cablin. The study was conducted with a Complete Randomized Design (CRD) with a single factor of A. conyzoides interference levels in as many as four treatments (0, 2, 4, 6 individuals of A. conyzoides per treatment). The results concluded that higher levels of A. conyzoides interference led to an increase in total phenol and total proline in P. cablin leaves, but decreased the percentage yield of P. cablin essential oil.

Abstract

Chili is used not only as a vegetable for consumption or a complement to dishes but also as an attractive ornamental plant to cultivate. One of the genetic enhancement efforts is through mutation induction with gamma rays. The aim of this study was to increase the genetic diversity of ornamental chilies by inducing gamma ray mutations. This research was conducted at BATAN (National Nuclear Energy Agency), experimental field and Plant Breeding and Biotechnology Laboratory, Faculty of Agriculture, Jenderal Soedirman University. The research was conducted from July to November 2022. The results showed that the LD50 value of gamma-ray irradiated chili seeds was 213.49 Gy, and there was an increase in the diversity of ornamental chili mutants. The color characteristic of mature leaves was purplish-green in the control plant, while the mutant turned purple on the upper and lower surfaces of the leaves. The character of the flower has not changed; that is, it remains purple, and the flower stalk remains upright. The stem pigment in control plants was a purple-green line, changed to purple in mutants. Mutant plant habitus changed to compact. These characters increase the aesthetic value of the ornamental chili mutant.
