Abstract

Kakao merupakan tanaman perkebunan yang mempunyai peran cukup penting dalam perekonomian nasional. Salah satu kendala pada budidaya kakao adalah kehadiran organisme pengganggu tanaman, yaitu kepik penghisap buah kakao (Helopeltis sp.). Pemakaian insektisida kimia secara berlebihan dapat menimbulkan dampak negatif sehingga diperlukan insektisida alternatif yang ramah lingkungan. Ekoenzim kulit pisang kepok manado muda memiliki kandungan bahan aktif yang berpotensi dijadikan insektisida nabati. Penelitian ini bertujuan untuk mengetahui konsentrasi ekoenzim kulit pisang kepok manado muda yang efektif dalam mematikan hama penghisap buah kakao. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) faktorial 2 faktor perlakuan dan 3 ulangan. Faktor pertama adalah konsentrasi ekoenzim (0%, 5%, 10%, 15%, dan 20%). Faktor kedua adalah waktu pengamatan (6, 12, 24, 48, dan 72 jam). Data hasil pengamatan dianalisis menggunakan ANOVA dengan uji lanjut Tukey dan nilai LC50 dianalisis menggunakan probit. Hasil penelitian menunjukkan bahwa ekoenzim kulit pisang kepok manado muda berpotensi sebagai insektisida nabati terhadap hama penghisap buah kakao dengan konsentrasi paling efektif adalah 20%. Sementara hasil analisis probit didapatkan nilai LC50 sebesar 17,95% pada waktu pengamatan 72 jam.

Abstract

Anoxygenic Photosynthetic Bacteria (APB) has beneficial properties including as probiotic candidates, biofertilizers, bioremediation agents, and can reduce H2S concentrations in waters. However, the APB also has a weakness, slow growth.It is known that the interaction of metal ions and the exposure of magnetic fields increases enzyme activity and growth rates. The aim of this study is to determine the effect of metal ions and the exposure to magnetic fields on APB growth. The APB isolate, AM which is isolated from mangrove roots and tested for its effects on metal ions in seawater complete (SWC) media.The metal ions tested were Cu, Pb, Al and Fe with different concentrations. The metal ion is exposed to a 0.2 mT magnetic field for 10 minutes before being added to the media. The cell count results showed that both metal ions exposed and unexposed to magnetic field did not affect the growth of APB AM isolates. However, the metal ion in SWC media affects the spectra pattern of AM APB isolates.

Abstract

Bromelain fiber is the product of extracting the enzyme bromelain from pineapple hulls or peels. Bromelain fiber contains lignocellulose, which, when fully decomposed, is very beneficial for the environment, but it is quite challenging to degrade naturally. Hence, it requires a decomposer agent. The decomposer agents used in this study were cellulolytic fungi Aspergillus sp. (Bioggp 3) and ligninolytic Trichoderma sp. (Bioggp 2). This study aims to determine the effect of compost tea (CT) bromelain fiber induced by these fungi and obtain the best dose of the CT on the growth of land kale (Ipomoea reptans Poir.). This research was conducted in April–July 2022 at the Microbiology Laboratory of FMIPA Unila. This study used a completely randomized design (CRD) with 7 treatments and 4 replications, namely P0 (control), P1 (ACT 25%), P2 (NACT 25%), P3 (ACT 50%), P4 (NACT 50%), P5 (ACT 75%), P5 (NACT 75%). The parameters measured were plant height and number of leaves. The data were analyzed using ANOVA α = 5% followed by the Least Significant Difference (LSD) test with a 5% confidence interval. This study showed that the results with the highest height value and number of leaves were found in P3 (ACT 50%) while the lowest was in P0 (water control). It can be concluded that the ACT and NACT significantly affect the height and number of leaves, and the best dose was found in ACT 50% starting from day 10, 15 , 20, and 25 after planting. Keywords: Aspergillus sp., bromelain fiber, compost tea, Ipomoea reptans Poir, Trichoderma sp.

Abstract

Cabai merah besar (Capsicum annuum L.) merupakan salah satu tanaman hortikultura yang memiliki banyak manfaat. Peran dan manfaatnya tersebut menjadikannya sebagai salah satu komoditas hortikultura dengan tingkat produktivitas yang tinggi. Produksi cabai merah besar (C. annuum L.) cenderung terus menurun dan salah satu penyebabnya yaitu gulma. Gulma yang biasa hidup berdampingan dengan tanaman hortikultura ialah rumput teki (Cyperus rotundus L.). Rumput teki mengandung senyawa alelokimia yang akan mempengaruhi tanaman disekitarnya. Senyawa alelokimia tersebut dapat memacu sekaligus menghambat pertumbuhan tanaman. Oleh karena itu dilakukan uji perendaman benih C. annuum L. di dalam ekstrak etanol daun C. rutundus L. untuk mengetahui pengaruhnya terhadap pertumbuhan C.annuum L. Penelitian ini dilakukan menggunakan Rancangan Acak Lengkap (RAL) dengan ekstrak etanol daun rumput teki (C. rotundus L.)  dalam 6 taraf konsentrasi (0%, 5%, 10%, 15%, 20%, dan 25%) dengan 4 kali pengulangan.  Parameter yang diamati yaitu persentase perkecambahan, tinggi tanaman, jumlah daun, panjang akar, berat basah tanaman, berat kering tanaman, kandungan klorofil dan skor keracunan. Data yang diperoleh dianalisis dengan ANOVA dan dilanjutkan uji lanjut Beda Nyata Jujur (BNJ) dengan taraf 5 % (α= 5 %). Hasil penelitian menunjukkan bahwa ekstrak rumput teki pada konsentrasi 5% dapat memacu pertumbuhan jumlah daun, menghasilkan jumlah berat basah dan berat kering terbesar pada tanaman cabai merah besar, sedangkan konsentrasi 25% dapat menghambat proses perkecambahan, menekan pertumbuhan tinggi tanaman, menekan jumlah kandungan klorofil dan menyebabkan keracunan pada daun.

Abstract

Infectious diseases are a significant public health issue in both developed and developing countries. Infectious diseases are caused by the bacteria Staphylococcus aureus and Escherichia coli, which cause high rates of morbidity and mortality. Treatment of infectious diseases caused by pathogenic bacteria generally uses antibiotics, but the continuous use of antibiotics can have side effects such as the occurrence of antibiotic resistance.  Diplazium esculentum is one of the medicinal plants that is often used to treat infectious diseases.  The content of secondary metabolite compounds contained in D. esculentum includes saponins, steroids, alkaloids, tannins, glycosides, triterpenoids, phenols, flavones, and flavonoids.  This study aims to determine the effect of bacteriostatic activity of ethanol extract of D. esculentum and its effective concentration in inhibiting the growth of pathogens S. aureus and E. coli.  The study was conducted using a Randomised Complete Block Design (RAKL) with four concentrations of ethanol extract of vegetable fern, namely 20%, 33%, 43%, and 50%.  As a positive control, the antibiotic chloramphenicol was used and the negative control used sterile distilled water.  Data in the form of inhibition zone diameter formed from each treatment were analysed using Kruskal Wallis non-parametric test and continued with Mann Whitney Post Hoc test.  The results of the study showed that the concentration of ethanol extract of D. esculentum showed bacteriostatic activity against S. aureus bacteria at concentrations of 43% and 50% with inhibition zones of 6.52 mm and 5.55 mm, as well as E. coli bacteria at concentrations of 43% and 50% with inhibition zones of 5.11 mm and 4.37 mm, but was not effective in inhibiting the growth of S. aureus and E. coli bacteria.

Abstract

Penelitian ini dilakukan untuk mengisolasi serta mengarakterisasi jamur endofit dari jaringan akar cabai rawit (Capsicum frutescens L.), serta mengevaluasi bioaktivitasnya sebagai agen biokontrol terhadap C. capsici dan sebagai pemacu pertumbuhan tanaman. Isolasi dilakukan menggunakan metode kultur jaringan tanaman, diikuti dengan identifikasi secara makroskopis dan mikroskopis. Uji aktivitas biokontrol dilakukan melalui metode dual culture, sedangkan kemampuan produksi Indole Acetic Acid (IAA) diuji menggunakan reagen Salkowski. Pengujian in vivo dilakukan untuk menilai kemampuan isolat dalam menekan keparahan penyakit dan meningkatkan pertumbuhan tanaman cabai rawit. Hasil penelitian menunjukkan bahwa beberapa isolat jamur endofit memiliki aktivitas antagonis terhadap C. capsici, dengan salah satu isolat (E2) menunjukkan daya hambat tertinggi. Isolat tersebut juga mampu memproduksi IAA dan memberikan pengaruh positif terhadap pertumbuhan tanaman, yang ditunjukkan oleh peningkatan parameter tinggi tanaman, jumlah daun, dan berat basah. Selain itu, aplikasi isolat E2 secara nyata menurunkan tingkat keparahan penyakit dibandingkan kontrol. Hasil ini mengindikasikan bahwa jamur endofit berpotensi sebagai agen biokontrol sekaligus pemacu pertumbuhan tanaman cabai rawit yang ramah lingkungan.
