Judul: Kemasan Aktif Oxygen Scavenging Berbasis Material Komposit Kitosan-Polivinil Alkohol untuk Minyak Ikan Lemuru (Sardinella sp.).
Abstrak: Active packaging is packaging in the formulation deliberately added with a material to improve its ability to enhance the quality, safety and sensory value of stuffs. Active packaging with oxygen scavenging has not applied for fish oil products. This research aimed to develop a model of active packaging oxygen scavenging from chitosan-PVA composite for Sardinella sp. fish oil. Research activities including formulation and characterization, model development, and capability level or functionalization of active packaging oxygen scavenging through the approach of fish oil quality changes during storage. Active packaging oxygen scavenging with chitosan-PVA composite showed that the physical properties (thickness 0.056 ± 0.006 mm, elongation at break percentage 151.37 ± 11.38%), were better than the control packaging (thickness 0.052 ± 0.003 mm, elongation at break percentage 120.04 ± 8.03%). The level of cability or functionalization of active packaging with oxygen scavenging approach fish oil quality changes during storage did not have a significant influence on the increase in iodine value, peroxide value and free fatty acid of fish oil.

Judul: Peningkatan Kualitas Minyak Ikan Sardin (Sardinella sp.) dengan Adsorben Alami
Abstrak: Fish oil as by product of sardine canning process was a potential source of ω-3 fatty acids. One method of improving the quality of sardine fish oil is by purification using adsorbens. Type of the adsorben which used in this research was natural adsorbens, such as chitosan, fish scales, and eggshells. The purpose of this study was to determine the quality of fish oil before and after addition of natural adsorben. Several fish oil analysis which used were gas chomatography (GC), free fatty acids (FFA), acid value (AV), and peroxide value (PV). The result of GC showed that ω-3 is the highest fatty acids content in fish oil, which is EPA 13,31% and DHA 11,99%. Then, after addition of natural adsorbens, quality of sardine fish oil was improved. The result showed FFA, AV, PV levels decreased. The best natural adsoben to decrease FFA and AV levels is eggshells 3% which can reduce FFA levels by 35,82% and AV by 36,10%. In the peroxide analysis, the best treatment is the addition of fish scales and eggshells 7% which can reduce AV levels by (21-23)%. FFA and AV levels of fish oil still on International Fish Oil standards (IFOS), whereas the PV levels is exceed from standards.

Judul: Jagorawi Toll Highway's Traffic Accident (1996-1997
Abstrak: Jalan tol Jagorawi adalah jalan tol yang pertama dibangun di Indonesia, menghubungkan antara Jakarta, Bogor dan Ciawi. Jalan tol telah dirancang sedemikian rupa untuk memberi keamanan bagi pemakai jalan, namun kenyataan yang ada memperlihatkan jumlah kecelakaan lalu lintas yang terjadi cukup besar. Penelitian ini bertujuan untuk melihat gambaran kecelakaan lalu lintas di jalan tol Jagorawi mengenai jalur dan ruas tempat kejadian, hari, waktu, serta cuaca saat kecelakaan terjadi. Hasil perhitungan memperlihatkan tingkat kecelakaan di jalur yang menuju arah Jakarta lebih tinggi daripada arah meninggalkan Jakarta. Pada setiap ruas di setiap jalur, tingkat kecelakaan yang mengakibatkan luka-luka jauh lebih tinggi daripada tingkat kecelakaan tanpa korban; namun belum bisa ditentukan ruas mana yang paling berbahaya karena belum ditemui adanya pola tertentu yang khas dari angka-angka hasil perhitungan tingkat kecelakaan per ruas yang ada. Frekuensi kecelakaan di hari Sabtu dan Minggu lebih tinggi dari hari-hari lain, untuk hari Sabtu frekuensi kecelakaan pada jalur yang meninggalkan Jakarta lebih tinggi sedangkan di hari Minggu lebih tinggi pada jalur menuju arah Jakarta. Kecelakaan lebih banyak terjadi pada siang hari, namun kecelakaan fatal lebih banyak terjadi di malam hari. Sebagian besar kecelakaan di jalan tol Jagorawi terjadi pada saat cuaca cerah, di alinemen jalan yang lurus dengan permukaan jalan yang kering.
