Abstract

The pineapple waste increased by the rise of production in pineapple, one of increasing pineapple waste is pineapple pulp (bromelain litter). The bromelain litter will be disadvantage for the environment, this matter could be solved by converting bromelain litter into compost. The composting process in this study used ligninolytic fungus (Trichoderma sp.). Composting technology which currently has rapidly developed is Aerated Compost Tea (ACT) or a derivate product of compost. The use of this study was to ensure the best incubation period of ACT bromelain litter which induced by Trichoderma sp. fungus on the growth of tomato (L. esculentum Mill.). The study was conducted using a completely randomized design (CRD) with 7 treatments and 3 replications, namely: P0= control (without ACT), P1= ACT bromelain 24 hours, P2= ACT bromelain 48 hours, P3= ACT bromelain 72 hours, P4= ACT bromelain and leaf litter 24 hours, P5= ACT bromelain and leaf litter 48 hours, and P6= ACT bromelain and leaf litter 72 hours. The variables observed were number of leaves and plant chlorophyll content. The data obtained were analyzed with ANOVA at the level of 5 % and tested for the Least Significant Difference (LSD) at the level of 5 %. The results of this study showed that ACT was induced by Trichoderma sp. fungus which effective for the vegetative growth of tomato (L. esculentum Mill.) is ACT bromelain litter with incubation period up to 72 hours (P3).

Abstract

A mangrove forest ecosystem is a place where many special Bacillus sp. found. This study aims to obtain Bacillus sp. isolates that can inhibit the growth of Vibrio sp. This study was conducted by selecting 77 Bacillus sp. isolates from the Hanura mangrove forest area. In addition, selected bacteria were tested for salt stress, pH stress, pathogenicity test, and antibiotic susceptibility test. Selected isolates were cultivated together with Vibrio sp. for 7 days. Bacillus sp. and Vibrio sp. cultured again with the addition of anoxygenic photosynthetic bacteria for 4 days. From the results of the initial selection, 4 isolates could inhibit the growth of Vibrio sp. The final results showed that Bacillus IL2K8 isolates were known to inhibit the growth of Vibrio sp., can grow at salinity 0%, 3%, 6% and pH 7 and pH 10. IL2K8 isolates are not pathogenic, resistant to amplicin antibiotics, streptomycin, nalidixic acid, and chloramphenicol but sensitive to trimethoprim antibiotics. In the joint culture of liquid media IL2K8 together with Anoxygenic Photosynthetic Bacteria (APB) isolates IL2K8 can inhibit the growth of Vibrio sp.

Abstract

Anthracnose disease caused by Colletotrichum acutatum and often attacks red chilies in Asia. Generally farmers use chemical fungicides in controlling this disease. Utilization of butterfly leaf extract as a natural fungicide can be an alternative for environmentally friendly control. This study aims to determine the effectiveness of ethanol extract of butterfly leaves and determine the best concentration of ethanol extract of butterfly leaves in controlling fungus. Colletotrichum acutatum on red chilies. The study used a RAL with seven concentrations of ethanol extract of butterfly leaves, there are  0%, 0.5%, 1%, 1.5%, 2%, 2.5%, 3%. Each treatment was repeated 4 times. The data obtained were analyzed by ANOVA and continued with the Least Significant Difference (LSD) test with a level of  5% (α = 5%). The results showed that the ethanol extract of butterfly leaves had no significant effect on mushroom colony diameter and weight loss. Significantly affect the incidence of disease and disease severity. The best concentration of ethanol extract of butterfly leaves in inhibiting the incidence and severity of anthracnose disease is 3%.INTISARIPenyakit antraknosa yang disebabkan oleh jamur Colletotrichum acutatum yang sering menyerang tanaman cabai merah di Asia. Fungisida kimia umumnya digunakan oleh para penati untuk mengendalikan penyakit ini. Pemanfaatan ekstrak daun kupu-kupu sebagai fungisida alami dapat menjadi salah satu alternatif pengendalian yang ramah lingkungan.   Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak etanol daun kupu-kupu dan mengetahui konsentrasi terbaik ekstrak etanol daun kupu-kupu dalam mengendaikan jamur Colletotrichum acutatum pada buah cabai merah (Capsicum annuum L.). Penelitian dilakukan menggunakan Rancangan Acak Lengkap (RAL) dengan tujuh konsentrasi ekstrak etanol daun kupu-kupu, yaitu 0 %, 0,5 %, 1 %, 1,5 %, 2 %, 2,5 %, 3 %. Setiap perlakuan dilakukan 4 kali pengulangan. Data yang diperoleh dianalisis dengan ANOVA dan dilanjutkan uji Beda Nyata Terkecil (BNT) dengan taraf 5 % (α= 5 %). Hasil penelitian menunjukkan ekstrak etanol daun kupu-kupu tidak berpengaruh nyata terhadap diameter koloni jamur dan susut bobot. Berpengaruh nyata terhadap kejadian penyakit dan keparahan penyakit.

Abstract

Buncis merupakan salah satu jenis kacang-kacangan yang cukup populer dikalangan masyarakat karena memiliki kandungan gizi yang tinggi dan memiliki potensi nilai ekonomi-sosial yang baik serta berdaya guna untuk mempertahankan kesuburan tanah. Rhizoctonia solanii merupakan salah satu mikoriza yang dapat dimanfaatkan untuk membantu meningkatkan proses penyerapan air tanah pada saat tanaman sedang mengalami cekaman kekeringan. Penelitian ini bertujuan untuk mengetahui efek pemberian Rhizoctonia solanii pada kandungan karbohidrat planlet buncis (Phaseolus vulgaris L.) dalam kondisi cekaman kekeringan secara in vitro. Penelitian ini menggunakan Rancangan Acak Lengkap Faktorial dengan 2 faktor, yaitu inokulasi Rhizoctonia dengan 2 taraf [V0 (tidak diinokulasi Rhizoctonia) dan V1 (diinokulasikan Rhizoctonia)] dan konsentrasi Poly Ethylene Glycol (PEG 6000) dengan 3 taraf [P0 (0 %), P1 (15 %) dan P2 (30 %)]. Data dianalisis dengan menggunakan ANOVA dan uji lanjut dengan Beda Nyata Terkecil (BNT) pada taraf nyata 5 %. Masing-masing konsentrasi dilakukan 4 kali ulangan dan setiap ulangan terdiri dari 3 biji buncis dalam setiap botol kultur. Hasil penelitian menunjukkan bahwa inokulasi mikoriza Rhizoctonia solanii belum memberikan pengaruh terhadap kandungan karbohidrat terlarut total planlet buncis dalam kondisi cekaman kekeringan secara in vitro.doi: http://dx.doi.org/10.23960/aec.v4.i1.2019.p73-80
