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.

Abstrak: The aim of this study was to observed quality of fresh milk reviewed by somatic cells count, fat and protein levels. This research was conducted in February 2011 to July 2012. There were 35 bulk milk were taken from six farms. Data were analyzed descriptively and using linear correlation. The highest number of somatic cell, fat, and protein 2 780 000.00 ± 1 146 423.01 cell/ml, 4.05 ± 0.34%, and 3.66 ± 0.28% respectively. The result showed that positive correlation between bulk milk somatic cells count with fat and protein levels from dairy farmers which suppliers of cheese industry.

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).
