Abstrak: The aim of this study was to observe the total number of microorganism and coliforms in Gouda cheese. Samples were taken every week for three consecutive weeks. As many as 10 samples of each Gouda cheese (Gouda young, middle, and old) were examinated using plate count method (pour plate method). The data was analyzed with t-student and Duncan test to compare the total number of microorganism and coliforms. The result showed that Gouda old cheese has the highest average number of total microorganism (1.4x108 cfu/gram). There was not any significant difference in the total number of microorganism between Gouda young cheese and Gouda middle cheese. The significant (p<0.05) difference in the total number of microorganism was showed with Gouda young cheese and Gouda old cheese; Gouda middle cheese and Gouda old cheese. The highest average number of coliform was found in Gouda young cheese (4.3x105 cfu/gram). There was not any significant difference in the total number of coliforms among all the three types of Gouda cheese (p>0.05). The presence of coliforms in Gouda cheese indicated any contamination during the process and reduced the quality.

Judul: Kualitas mikrobiologi keju: keberadaan staphylococcus aureus pada tahap pembuatan keju gouda
Abstrak: Milk and its derivative products could potentially transmit pathogenic microorganisms from animals to human. Staphylococcus aureus is one of the microorganisms that commonly presents in milk and dairy products. This bacteria is often associated with foodborne disease outbreaks due to the ability of some strains to produce thermostable enterotoxins. The aim of this study was to analyze the presence of S. aureus during the Gouda cheese manufacturing process. Samples were obtained from every stages of Gouda cheese production. Staphylococcus aureus analysis was performed using pour plate method in Vogel Johnson agar. The number of S. aureus in raw milk was 2.4 x 103 CFU/ml (exceeding the maximum level for contaminant specified by BSN in SNI No. 3141.1-2011). The number of this bacteria increased in the following stages. The highest level was reached in young Gouda cheese (3.6 x 106 CFU/g). This level significantly increased from ripened cheese to become young Gouda cheese and remained stable during the ripening process. The high level of S. aureus in Gouda cheese (exceeding the maximum level for contaminant specified by BSN in SNI No. 7388-2009) indicates it could be potentially cause foodborne disease.

Judul: Pengelolaan Lanskap Pada Habitat Bersarang dan Habitat Berburu Elang Jawa (Nisaetus bartelsi) di Taman Nasional Meru Betiri, Jawa Timur
Abstrak: Jawa Timur memiliki hutan dataran rendah terbesar di Pulau Jawa. Taman Nasional Meru Betiri (TNMB) adalah salah satu taman nasional yang memiliki hutan dataran rendah yang merupakan habitat bagi elang jawa (Nisaetus bartelsi) yang merupakan satwa dengan status genting (endangered species) dan masuk kedalam 25 spesies prioritas yang harus ditingkatkan populasinya sebanyak 10% sampai tahun 2019. Elang jawa merupakan satwa prioritas di TNMB sehingga sangat perlu informasi terkait habitatnya untuk kemudahan kegiatan monitoring. Tujuan penelitian ini untuk memetakan habitat bersarang dan habitat berburu serta menganalisis preferensi habitat keduanya untuk dapat memberi rekomendasi pengelolaan habitat elang jawa di TNMB. Observasi dilakukan di sekitar habitat bersarang dan berburu elang jawa atau dari data perjumpaan Elang Jawa. Preferensi habitat elang jawa dianalisis menggunakan analisis vegetasi dalam purposive sampling plots. Hasil menunjukkan bahwa di TNMB elang jawa menggunakan hutan dataran rendah dengan ketinggian 0-200 mdpl serta kemiringan 3-8% dan 8-15% yang masuk kedalam zona rimba TNMB dan berada tidak jauh dari area perkebunan milik PT. Bandealit untuk bersarang dan berburu. Preferensi pohon bersarang elang jawaadalah dari pohon strata A yang memiliki ketinggian 30-40 m dan strata B dengan ketinggian 20-30 m untuk habitat berburu dan bersarang. Elang jawa menggunakan pohon bindung (Arthocarpus elastica) yang memiliki model arsitektur rauh. Rekomendasi pengelolaan lanskap pada habitat elang jawa di TNMB dibedakan untuk habitat bersarang dan habitat berburu dan juga ada pengelolaan untuk keduanya seperti menambah fasilitas untuk memudahkan kegiatan monitoring elang jawa, menerapkan manajemen tumbuhan invasif di preferensi habitat elang jawa yang ada di Taman Nasional Meru Betiri, serta memfokuskan monitoring elang jawa di preferensi habitatnya.
