Abstract

Percobaan ini dilakukan untuk mengetahui pengaruh pupuk organik hayati diperkaya mikrob tanah terhadap keragaan tanaman, populasi total mikrob dan populasi mikrob pelarut fosfat di pembibitan kelapa sawit. Persiapan media tanam dilakukan dengan mengambil lapisan tanah atas (topsoil) dengan kedalaman maksimal 25 cm kemudian tanah tersebut dikering anginkan dan dimasukkan ke dalam setiap kantong plastik media tanam dengan volume masing-masing 5 kg. Pengukuran parameter keragaan tanaman bibit kelapa sawit dilakukan dari minggu ke-4 setelah tanam (MST) hingga ke-22 MST di rumah kaca kebun percobaan Cikabayan, Darmaga. Percobaan uji efektivitas mikrob pelarut fosfat (MPF) pada pupuk organik hayati menggunakan Rancangan Acak Kelompok (RAK), yang terdiri dari dua faktor dengan tiga ulangan. Hasil percobaan menunjukkan pengaruh penggunaan pupuk batuan fosfat terhadap tinggi tanaman memberikan hasil yang lebih baik dibandingan penggunaan SP-36 dan analisa statistik terhadap pengaruh tunggal pupuk organik hayati, pengaruh pupuk organik terhadap populasi total mikrob menunjukkan hasil terbaik.

Abstract

This study aimed to determine the ability of microorganisms originating from the root ecosystem (Rhizosphere) of cocoa (Theobroma cacao L) as a potential superior to biological agents. For the experiment, soil samples were observed from the rhizosphere of cocoa plants in Pandeglang Regency. At this stage, the research was focused on finding out the extent of microbe screening results from cocoa rhizosphere soil in producing phytohormones. The results from the initial selection showed a population of Azotobacter 2.8 x 105 cfu/mL, a population of Azospirillium of 0.3 x 102 cfu/mL, and a population of Phosphate-solubilizing bacteria (PSB) 4.1 x 107 cfu/mL. In the hemolysis test conducted for 9 isolates, only 1 isolate showed a negative result. From the test of the ability to produce phytohormones showed respectively from the highest values were IAA 5.467 mg/L, gibberellin 3.768 mg/L, zeatin 1.321 mg/L, and kinetin 0.886 mg/L. The land rhizosphere of Pandeglang cocoa plant had superior potential microbes which could be used as biological fertilizers.

Abstract

ABSTRACTThis experiment was continues from the study of biological fertilizers potential’slocal microorganisms from the best main raw materials obtained from previousexperiments. This experiment used five selected raw materials to make localmicroorganisms, including: bamboo roots, broccoli leaves, chicken manure, rabbit manure and goat manure, each raw material was made 2 times so that there were 10 local microorganisms samples. The results showed that the highest of total bacterial population were shown by local microorganisms goat manure with a value of 7.2 x 105 cfu/ml, then the highest population of Azotobacter and Azospirillium were shown by local microorganisms rabbit manure with values of 6.4 x 104 cfu/ml and 3.5 x 103 cfu/ml and total fungi populations was local microorganisms goat manure with a value of 4.7 x 103 propagules/ml. In the pathogenicity test, 9 nine bacterial isolates were obtained, 25 Azotobacter isolates, 15 Azospirillium isolates were proven to provide negative responses to the pathogenicity test. Furthermore, in the seed nurserytest, only 33 microbial isolates were obtained which could support the growth ofpaprika seeds with the best results were shown by aquadest water control, 4B-1 NFB, 5A-1 NFB, and 1A-2 NFB isolates respectively.

Abstract

Local microorganisms (MOL) are liquid fertilizers commonly used by farmers to help increase crop production. Beneficial microbes in MOL need to characterize their interactions and ability to produce growth drive compounds. The purpose of this research is to identify the superior microbial isolates from MOL made by farmers from Cibodas Lembang Bandung, Indonesia that can produce phytohormones as biofertilizers. The results of the microbial selection of MOL derived from three best microbes are 1A-2 NFB, 4A-1 NFB, and 4B-1 NFB with the ability to produce auxin, i.e., 19.41 ppm, 17.18 ppm, and 10.59 ppm, respectively. The compatibility test between the three isolates showed negative results so that it was possible to apply three microbes as a consortium. The results of a molecular identification with a 16S rRNA analysis indicate strain microbe 1A-2 NFB: Bacillus cereus (99.88% homology), 4A-1 NFB: Bacillus cereus (99.76% homology), and 4B-1 NFB: Lysinibacillus sp. (99.88% homology).

Abstract

This research was conducted to investigate the effects of papaya fruit local microorganisms (MOL) dosage and plant population on growth and yield of long beans (Vigna sinensis L.). The experimental design employed in this research was a Factorial Randomized Complete Block Design consisting of two factors; MOL dosage and plant population. The first factor, MOL dosage (M), included four levels: 0 ml, 37,5 ml, 75 ml and 112,5 ml. The second factor, plant population (P) included 3 levels: 1, 2 and 3 plants per polybag. The research results showed that a MOL dosage of 112,5 ml gave the best effect on the number of pods and pod weight of long beans. The population of 1 plant per polybag gave the best effect on plant height, number of leaves, number of pods, pod weight as well as fresh and dry weight of the crown. There was an interaction between treatments on the height of long beans at 4 weeks after planting with the M1P1 treatment combination and the number of pods at the second harvest with the M3P3 treatment combination. Keywords: local microorganism, plant population, long beans INTISARIPenelitian ini bertujuan untuk mengetahui pengaruh dosis mikroorganisme lokal (MOL) buah pepaya dan populasi tanaman terhadap pertumbuhan dan hasil kacang panjang (Vigna sinensis L.).

This research aimed to determine the effect of the dose and time of application of Moringa leaf POC on the growth and yield of green mustard plants (Brassica juncea L.). The research used in a Randomized Block Design with two factors. The first factor is the POC dose of Moringa leaves consisted of 5 levels: 65 ml/L, 70 ml/L, 75 ml/L, and 80 ml/L. The second factor is the time of application of Moringa leaf POC consisted of 3 levels: every 5 days, every 7 day, and every 9 days. The results showed that the application of a Moringa leaf POC at a dose of 80 ml/L had a significant effect on the parameters of plant height, number of leaves, leaf area, plant wet weight, and plant dry weight. The application time of Moringa leaf POC every 5 days has a significant effect on all observation parameters. There was an interaction between the two factors with the best average results from a treatment dose of 80 ml/L with an application time of 5 days on the parameters of leaf area at 3 WAP and 4 WAP, leaf area, and plant fresh weight.   Keyword : application time, mustard green, POC dosage INTISARIPenelitian ini bertujuan untuk mengetahui pengaruh dosis dan waktu pengaplikasian POC daun kelor terhadap pertumbuhan dan hasil tanaman sawi hijau (Brassica juncea L.)

Abstract

The research was aimed to know the viability response of arabica coffee (Coffea arabica L.) seed to sulfuric acid (H2SO4) immersion treatment. The experimental design used in this study was the Completely Randomized Design which consisted two factors. The first factor is the immersion time, which consists of three levels, namely M1 : 15 minutes,  M2 : 20 minutes,  and M3:  25 minutes. While the second factor is the concentration of H2SO4, which consists of four levels, namely K0 : 0%, K1: 10%, K2 : 20%, and K3 : 30%. The results showed that there was no interaction of H2SO4 concentration treatment and immersion time had a significant effect on the germination. The treatment duration of immersion had a significant effect on the parameters of potential to grow, index vigor and percentage of abnormal germination. The concentration of sulfuric acid effects had a significant effect on the parameters of potential to grow, simultaneity grow,  index vigor and percentage of abnormal germination Keyword :   Coffea, sulfuric acid, germination.INTISARIPenelitian ini bertujuan untuk mengetahui pengaruh lama perendaman dan berbagai tingkat konsentrasi H2SO4 terhadap perkecambahan benih kopi arabika (Coffea arabica L.)Penelitian ini menggunakan rancangan acak lengkap faktorial.
