Berdasarkan hasil penelitian tersebut menunjukkan bahwa serbuk daun J. curcas mampu mengendalikan Meloidogyne spp. pada tanaman tomat.Jathropa (Jatropha curcas L.) Leaf Powder Test to Control Root-knot Nematodes (Meloidogyne spp.) on Tomato PlantsMeloidogyne spp. is one of important pathogen on tomato. Previous reports show that Jatropha. curcas has active ingridiens as nematicide. In this research we employ J. curcas leaves in powder form to control the pathogen. The aim of this study is to examine several dosages of J. curcas leaves powder (0; 1,5; 2,5; 3,5; 4,5 g/kg of soil) to control Meloidogyne spp. The nematicide was applied on the rhizosphere of the plant artificially. The observation was including incubation time, percentage of affected plant, number of galls, and nematode population. The results show that J. curcas leaves powder at 3.5 g/kg of soil prolongs the incubation time, suppress disease intensity, decrease the number of galls and Meloidogyne spp. population up to 60%, 62%, 87% and 54%, respectively. The results indicate that J. curcas leaves powder capable of controlling Meloidogyne spp. on tomato plant

Kemampuan rizobakteri dalam memproduksi IAA terbaik adalah GM 8/1, dan semua isolat rizobakteri yang diuji mampu melarutkan fosfat (P). Pertumbuhan vegetatif tanaman kakao pada umur 35 HSTdapat dilihat dari hasil penelitian ialah bahwa tinggi bibit kakao, diameter batang dan jumlah daun yang diberikam perlakuan rizobakteri pada benih berpengaruh yang sangat berbeda nyata dibandingan pada tanaman yang tidak diberikan perlakuan rizobakteri pada benih (kontrol). Hal ini dikarenakan salah satu fungsi IAA sebagai agen PGPR dalam memacu pertumbuhan tanaman kakao.Seed Treatment Using Various Rhizobacterial Isolates On The Growth of Cocoa Seeds (Theobroma cacao L.)This study aims to obtain PGPR agents that can increase the growth of cocoa seedlings by using rhizobacteria. This research was conducted at the Seed Science and Technology Laboratory, Department of Agrotechnology, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh. This research was conducted from September 2020 to February 2021. This study used a completely randomized design with a non-factorial pattern consisting of 10 treatments and each treatment was repeated 3 times, so there were 30 experimental units. Parameters observed were inhibition, rate of inhibition of pathogenic colony growth, maximum growth potential, germination, vigor index, simultaneous growth, relative growth rate, time required to reach 50% relative germination, vegetative growth of cocoa seedlings including plant height, number of leaves and stem diameter. The results obtained in vitro are that there is a very significant effect on the inhibition and rate of inhibition of the growth of the pathogenic colony of P. palmivora with the best inhibition found by the rhizobacteria isolate TRI 3/3 with an inhibition value of 47.67% which is classified into activity low (+= 50% DH), and the best isolate of rhizobacteria in the rate of inhibition of pathogenic colonies was found by isolate GM 3/6 with an inhibition rate of 23.37mmday-1. Cocoa seed vigor in growth potential variables Maximum germination was found by TRI 6/6 rhizobacteria isolates, then vigor index, simultaneous growth was found by TRI 8/4 isolates, while GM 5/6 isolates were the best isolates in growth velocity variables and GM 8/1 isolates were the best isolates in this variable. time required to achieve 50% relative germination. The best ability of rhizobacteria to produce IAA was GM 8/1, and all tested rhizobacteria isolates were able to dissolve phosphate (P). Vegetative growth of cacao plants at 35 DAP can be seen from the results of the study that the height of cacao seedlings, stem diameter and number of leaves treated with rhizobacteria on seeds were significantly different compared to plants that were not treated with rhizobacteria on seeds (control). This is because one of the functions of IAA is as a PGPR agent in spurring the growth of cocoa plants

This research method uses a Randomized Design of 4x3 Factorial Pattern Groups with 2 factors and 3 repeats with a total of 36 units of experiments and observations are carried out every 3 days. Factor I is the concentration of beeswax (2%, 4%, 6%). Factor II is the Type of Material (Foam Net, Plastic Wrap and Newspaper). The parameters measured are weight shrinkage, water content, sugar level test, vitamin C level test, color measurement of color against color L (Brightness), color a (Green), and color b (Yellow), and Organoleptics against outer color, inner color, texture, aroma, taste and overall reception. The results showed that the concentration of beeswax had a very real effect on organoleptics of outer color, a noticeable effect on sugar levels, organoleptics of inner color, texture and taste, and an unreal effect on weight shrinking, moisture content, vitamin C levels, L color (brightness), color a (red), color b (yellow), organoleptics on aroma and overall acceptance. The best results are found in no control (K0). The results showed that the type of material had a noticeable effect on sugar levels, as well as an unreal effect on weight shrinkage, water content, vitamin C levels, L color (brightness), color a (green), color b (yellow), organoleptic on the outer color, inner color, texture, aroma, taste and overall reception. The best results are found in the type of newspaper material (P3). There is a noticeable interaction between the concentration of beeswax and the type of material in the parameters of weight shrinkage, water content, sugar content, vitamin C levels, L color (brightness), color a (green), color b (yellow), organoleptic on the outer color, inner color, texture, aroma, taste and overall reception

    Tujuan dari penelitian adalah untuk mengetahui pengaruh konsentrasi BAP dan NAA serta interaksi antara kedua faktor terhadap pertumbuhan tunas eksplan pucuk tanaman nilam varietas Tapak Tuan secara in vitro. Penelitian ini dilaksanakan di Laboratorium Kultur Jaringan Tanaman Fakultas Pertanian Universitas Syiah Kuala, Darussalam, Banda Aceh.Penelitian berlangsung dari bulan April sampai Juli 2021. Penelitian ini terdiri dari 2 faktor, faktor pertama adalah konsentrasi BAP yang terdiri dari 5 taraf yaitu kontrol, 0,25 mg L-1 , 0,5 mg L-1, 0,75 mg L-1, dan 1 mg L-1. Faktor kedua adalah konsentrasi NAA yang terdiri dari 4 taraf yaitu kontrol, 0,25 mg L-1 , 0,5 mg L-1, dan 0,75 mg L-1, sehingga terdapat 20 kombinasi perlakuan. Hasil penelitian menunjukkankonsentrasi BAP dan NAA berpengaruh pada persentase pembentukan kalus terbaik (100%) dijumpai pada konsentrasi 0,25 mg L-1 NAA dan 0,75 mg L-1 NAA. Persentase jumlah akar dengan konsentrasi 0,75 mg L-1 NAA menghasilkan jumlah akar yang lebih banyak yaitu sebesar 7,8 akar, dibandingkan dengan perlakuan lainnya.Induction of Patchouli Callus (Pogostemon cablin Benth,) using Benzyl Amino Purine and Naphtalene Acetic Acid under In Vitro ConditionThe purpose of this study was to determine the effect of BAP and NAA concentrations and the interaction between these two factors on the growth of explant shoots. patchouli shoots of the Tapak Tuan variety in vitro. This research was conducted at the Plant Tissue Culture Laboratory, Faculty of Agriculture, Syiah Kuala University, Darussalam, Banda Aceh. The study took place from April to July 2021. This study consisted of 2 factors, the first factor was the concentration of BAP which consisted of 5 levels, namely control, 0.25 mg L-1, 0.5 mg L-1, 0.75 mg L- 1, and 1 mg L-1. The second factor wasthe concentration of NAA which consisted of 4 levels, namely control, 0.25 mg L -1, 0.5 mg L-1, and 0.75 mgL-1,so there were 20 treatment combinations. The results showed the combination of BAP and NAA had an effect on the proportion of callus formation, the best percentage of callus formation (100%) was found atoncentrations of 0.25 mg L-1 NAA and 0.75 mg L-1 NAA. The percentage of the number of roots with a concentration of 0.75 mg L-1 NAA resulted in a larger number of roots, which was 7,8 roots, compared to other treatments
