Abstract

The study aimed to investigate the use of wood sawdust as a medium for growth and the optimum addition ratio of plantation wastes that can increase the yields and quality of white oyster mushroom (Pleurotus ostreatus). This research used Completely Randomized Design (CRD) consisting of 7 levels of treatment ratio of  wood sawdust and plantation wastes. The data analysis involved one way ANOVA followed by Duncan’s 5%. The results showed that the wood sawdust can be used as growing medium, and the addition of plantation wastes can increase the yields and the quality of white oyster mushroom. The addition of cocoa and coffee wastes with a ratio 25% was the optimum ratio treatment which increased the number of fruiting bodies, caps diameter, production weight, Biologycal Eficiency Ratio (BER) and protein, fats, carbohydrates and fiber content in white oyster mushrooms. It is recommended to be applied because both treatments would increase the yield and quality of white oyster mushroom.

Abstract

Penelitian ini bertujuan untuk: 1) menguji daya antibakteri ekstrak buah lerak (Sapindus rarak dc) tanpa kulit dan ekstrak buah lerak (Sapindus rarak DC) beserta kulit dalam menghambat pertumbuhan Propionibacterium acnes, 2) menentukan kombinasi perlakuan macam ekstrak (ekstrak buah lerak tanpa kulit dan ekstrak buah lerak beserta kulit) dan konsentrasi ekstrak (5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45% dan 50%) yang paling efektif dalam menghambat pertumbuhan Propionibacterium acnes. Pengujian daya antibakteri menggunakan metode difusi agar atau metode sumuran. Daya antibakteri ditentukan berdasarkan rerata diameter zona hambat yang terbentuk. Hasil pengukuran dianalisis menggunakan Two Way ANOVA dan uji lanjut Duncan’s Multiple Range Test (DMRT). Berdasarkan hasil analisis diperoleh nilai signifikansi macam ekstrak (0.009) < α (0.05), maka disimpulkan macam ekstrak berpengaruh terhadap diameter zona hambat Propionibacterium acnes. Nilai signifikansi macam konsentrasi (0.002) < α(0.05), maka disimpulkan macam konsentrasi berpengaruh terhadap diameter zona hambat Propionibacterium acnes. Nilai signifikansi macam ekstrak dan macam konsentrasi (0.055 )=α(0.05), sehingga disimpulkan interaksi macam ekstrak dan macam konsentrasi berpengaruh terhadap diameter zona hambat Propionibacterium acnes. Berdasarkan uji lanjut DMRT diketahui kombinasi perlakuan ekstrak buah lerak tanpa kulit dengan konsentrasi 30% memberikan perngaruh paling besar terhadap rerata diameter zona hambat pertumbuhan Propionibacterium acnes, tetapi tidak berbeda nyata dengan ekstrak buah lerak beserta kulit dengan konsentrasi 25%, hasil penelitian ialah: perlakuan ekstrak buah lerak tanpa kulit dengan konsentrasi 30% dan ekstrak buah lerak beserta kulit dengan konsentrasi 25% merupakan kombinasi perlakuan paling efektif dalam menghambat pertumbuhan Propionibacterium acnes.

Abstract

Coriander is commonly used by people as a food flavour. Actually, people does not separate the intact and damaged coriander for food processing. The aim of this study is to examine the microbiological quality of the intact and damaged coriander based on the Total Plate Count (TPC) of mold colonies and identification of the mold contaminants. Identification of contaminants mold based on the colony and microscopic character description. Then, the fungi characters refers to the identification key book for fungi identification. The research results is: 1) the intact coriander TPC is 1.6 x 103 colonies/g and the damaged coriander TPC 1.4 x 107 colonies/g. 2) There are 10 species of molds contaminant isolated from the intact coriander and damaged coriander.

Abstract

Learning media is one of the most important component in a learning process, both inside or outside a classroom. In order to provide proper learning for students based on the researcher’s prior research, at least, three different field tests are needed. This research is a quasi-experiment, which is provide result of the second field test of cellulose degrading bacteria from mangrove soil microbiology handout both in cognitive and psychomotor ability. The research aims are to describe effect of this microbiology handout on student’s cognitive achievement and gain data about inappropriate laboratory written instruction in this handout. Data gained by conducting learning activities using developed handout which were 2 times in class theory and three times of practical activity using instuctions written in the handout. In the end of class theory activity, students did a posttest to confirm their improvement of cognitive ability while their practical ability was observed using observation sheet along with their activities. Results showed that handout which being tested could improve student cognitive at average level (n gain 0,419). In contrast, several parts of laboratory written instruction need to be fixed to make better microbiology handout.

Abstract

Biji kedelai dapat mengalami kerusakan, antara lain: karena pemanenan yang kurang cermat, serangan serangga hama di lahan pertanian, gigitan serangga di tempat penyimpanan biji sebelum dijual, serta terkontaminasi oleh kapang penghasil mikotoksin di pasar. Fokus dari penelitian ini ialah: 1) mengisolasi dan mengidentifikasi semua jenis kapang kontaminan pada biji kedelai yang dijual di beberapa pasar di Kota Malang, 2) menentukan jenis kapang kontaminan yang paling dominan dalam biji kedelai yang diteliti, dan 3) mengkaji dampak cemaran kapang kontaminan terhadap penurunan kualitas biji kedelai berdasarkan kajian pustaka. Data diperoleh melalui metode observasi, deskripsi, dan identifikasi semua jenis kapang kontaminan yang ditemukan pada biji kedelai yang diteliti. Selanjutnya dilakukan identifikasi dengan deskripsi morfologi koloni dan mikroskopis kapang. Hasil yang diperoleh yaitu tujuh isolat jenis kapang kontaminan, yakni Scopulariopsis brevicaulis, Penicillium frequentans, Aspergillus tamarii, mycelia sterilia I, Aspergillus oryzae, Aspergillus ochraceus, dan mycelia sterilia II; 2) jenis kapang kontaminan yang paling dominan yaitu Aspergillus ochraceus; 3) cemaran kapang berdampak terhadap penurunan kualitas biji kedelai, yaitu: tekstur biji berserbuk, hancur, keriput, berbau apak, dan berpotensi tercemar oleh mikotoksin yang dihasilkan kapang kontaminan.
