Judul: Preservation Vy Using Natural Compound of Picung Kernel (Pangium edule ReinW) Influence on Freshness and Safety of Marckerel (Rastrelliger brachysoma blkr)
Abstrak: The lack of ice used as fish freshness control leads the fisherman to use picung kernel (Pangium edule ReinW) to manage the fish freshness. Beside consumed traditionally as food in Indonesia, the picung kernel is also used as a medical substance to cure scabies, as insecticide, soap, or as a raw material for adible oil and colourant of yarn, or as fish presertative.

Judul: Fresh kembung (Rastrelliger brachysoma) fish preservation technology by using natural compound of picung kernel (Pangium edule Reinw)
Abstrak: The lack of ice used as fish freshness control leads the fisherman to use picung kernel (Pangium edule Reinw) to manage the fish freshness. Beside consumed traditionally as food in Indonesia, the picung kernel is also used as a medical substance to cure scabies, as insecticide, soap, or as a raw material for edible oil and colourant of yarn, or as fish preservative. Picung is widely available in Indonesia so that enable to use in several fishing grounds and fishing ports which suffer from ice deficiency. Based on the experimental result on the addition of picung kernel and salt to fresh fish (Rastrelliger brachysoma), the proportion of salt : picung kernel, from 2%:2%, 2%:4%, 2%:6%, 3%:2%, 3%:4% and 3%:6% were found inhibit the decomposition rate of fish due to the reduction of bacterial growth (Total Plate Count, Enterobacter dan H2S Producer). The proportion of picung kernel 2% was the most effective and very economic to use in the preservation of mackerel. The result was to demonstrate that the antimicrobe substance contained in the picung kernel may be used as natural preservative for fish products and seems to increased the shelf life of the fish within 6 days, stored at ambient temperature.

Judul: Analisis Dinamik Struktur Gedung Terhadap Beban Gempa (Studi Kasus Tower Altiz – Tangerang Selatan).
Abstrak: Penelitian ini bertujuan untuk melakukan pemodelan gedung, menganalisis besarnya periode getar dan kekakuan yang dimiliki gedung, menentukan mode shape dan partisipasi massa, serta menganalisis besarnya gaya geser dasar gempa. Objek penelitian adalah Tower Altiz. Prosedur penelitian mengacu kepada SNI 1727-2013, SNI 1726-2012, SNI 2847-2013, dan PPURG 1987. Berdasarkan hasil penelitian, pemodelan Tower Altiz telah berhasil dilakukan. Periode getar yang dialami Tower Altiz adalah 2.735 detik. Mode shape dari Tower Altiz telah berhasil didapatkan. Untuk besarnya partisipasi massa pada arah x yang lebih dari 90 %, didapat pada mode ke-10, sedangkan untuk partisipasi massa pada arah y didapat pada mode ke-11. Gaya geser dasar statik (Vstatik) sebesar 11359.164 kN sedangkan besarnya gaya geser dasar dinamik (Vdinamik) 8339.260 kN untuk arah gempa-x dan 7722.238 kN untuk arah gempa-y. Faktor skala desain untuk gaya geser dinamik (Vdinamik) sumbu-x adalah 1.15, sedangkan untuk sumbu-y adalah 1.25. Besarnya gaya geser dinamik (Vdinamik) yang diperoleh untuk sumbu-x dan sumbu-y adalah 9655.289 kN.
