Judul: Komposisi, Kesegaran, dan Dugaan Pemalsuan Susu Segar sebagai Bahan Dasar Keju pada Industri Pengolahan Susu (IPS)
Abstrak: Composition of fresh milk as cheese raw material determines quality of the cheese. The freshness of the milk should be guaranted and not falsified, according to SNI No. 01−3141 − 2011 about Fresh Milk. This study aims to examine the composition of fresh milk, freshness of milk, and falsification supposition of fresh milk were used as a cheese raw material in the milk processing industry. The milk composition test consist of specific gravity, fat content, solid content, solid-non-fat content, and protein content. Freshness of milk test were did by alcohol test, boiling test, and measurement of the degree of acidity (pH). Falsification supposition test were did by Storch test, carbonate test, coconut-milk test, and starch test. Data were analyzed descriptively and compared with SNI. Samples of milk were examined are incompatible with SNI as much as 94.28% for specific gravity, 37.14% for solid-non-fat content, 14.28% for protein content, and 2.86% for solid content, while the milk fat content entirely in accordance with SNI. In addition, it is known that as much as 17.14% of the sample did not have similar specified range of pH values on SNI and 17.14% of the sample were experiencing addition of cooked milk. Milk samples examined still can be used as raw material for cheese, but the cheese produced can undergo degradation.

Judul: Kualitas Mikrobiologis Susu Segar sebagai Bahan Baku Keju
Abstrak: The aim of this study was to observe microbiological quality of fresh milk as the raw material of cheese. There were 35 milk samples taken from six farms. The total count of microorganisms, Staphylococcus aureus, and coliforms were examined with plate count method (pour plate method). The result showed that the milk samples from the third farm had the highest number of total plate count (6 973 333.3 + 4 712 126.2 cfu/ml), the fifth farm showed the highest number of Staphylococcus aureus (1 950.0 + 636.4 cfu/ml), and of coliform (321 139.2 + 4 177 723.8 cfu/ml). Compared to the maximum number of microbial contamination according to the Indonesia National Standard (SNI 01-3141-2011), all the samples (100%) from the six farms were higher than the standard. The high number of Staphylococcus aureus and coliform contamination in milk due to the inadequate personal hygiene practices and the poor cleanliness level of water, cages, and equipment. This condition should be considered as a risk of food contamination that can cause disease for the consumers.

Judul: Ekologi pecuk hitam (Phalacrocorax sulcirostris Brandt, 1931) di Taman Burung Kota Baru Bandar Kemayoran Jakarta
Abstrak: Kota Baru Bandar Kemayoran (KBBK) terletak di pusat kota Jakarta dan kaya akan avifauna. Di dalam kawasan ini direncanakan pengembangan suatu taman burung, yang selain berfungsi untuk perlindungan juga berfungsi untuk kegiatan rekreasi bersifat mendidik, khususnya rekreasi pengamatan burung (bird watching). Salah satu jenis burung yang menarik untuk diamati yaitu Pecuk Hitam (Phalacrocorax sulcirostris), yang merupakan jenis dominan dan sering dijumpai. Jenis ini mempunyai perilaku khas yang tidak dimiliki oleh spesies lain, yaitu tarian gerakan sayap untuk menarik pasangan (wing waving) dan gerakan membuka sayap membentuk sudut patah di bagian siku berbentuk delta winged disebut wing spreading. Berdasarkan pengamatan awal, populasi Pecuk Hitam tersebar pada hampir semua tipe habitat, meliputi: habitat rawa, habitat mangrove, habitat semak dan habitat waduk buatan, sehingga mudah dijumpai, terutama di waduk buatan. Kondisi ini sangat baik untuk pengembangan rekreasi pengamatan burung (bird watching).
