Judul: Morphological and morphometric identification of  fruit flies Bactrocera spp. at Agricultural Quarantine Standards Test Centre
Abstrak: Identifikasi secara morfologi dilakukan dengan cara mengamati seluruh karakteristik bagian tubuh serangga. Morfometri merupakan ciri yang berkaitan dengan ukuran bagian tubuh serangga. Analisis morfometri ini memiliki kaitan yang erat dengan faktor-faktor yang mempengaruhi pertumbuhan serangga. Lalat buah merupakan hama penting karena menimbulkan kerugian yang cukup besar baik di dunia maupun di Indonesia. Pada lalat buah, bagian tubuh yang harus diamati dalam identifikasi sampai ke tingkat spesies adalah karakteristik pada bagian kepala, toraks, sayap, abdomen dan tungkai. Penelitian ini bertujuan untuk mengetahui perbedaan karakteristik morfologi dan morfometri lalat buah Bactrocera spp. dan membuat kunci identifikasi menggunakan buku kunci identifikasi dan program Lucid Key ID dalam kegiatan magang di Balai Besar Uji Standar Karantina Pertanian. Jenis hama lalat buah yang diidentifikasi selama kegiatan magang adalah B. carambolae, B. papayae, B. albistrigata, B. umbrosa, B. caudata, B. cucurbitae, sedangkan hama karantina lalat buah adalah B. occipitalis, B. musae, B. correcta, dan B. zonata. Hasil identifikasi menggunakan buku kunci identifikasi disajikan dalam bentuk format teks, sedangkan hasil identifikasi menggunakan program Lucid Key ID disajikan dalam bentuk format matriks. Hasil pengukuran morfometri yang dapat dijadikan acuan dalam identifikasi lalat buah adalah pengukuran lebar lateral postsutural vittae dan lebar mesopleural stripe., Morphological identification was done by observing all the characteristics of the insect's body parts. Morphometry is a characteristic related to the size of insect body parts. This morphometric analysis is related to the factors that influence insect growth. Fruit flies are important pests because they cause considerable losses both in the world and in Indonesia. In fruit flies, the body parts that must be observed in identification to the species are the characteristics of the head, thorax, wings, abdomen, and legs. This research aims to determine the differences in morphological and morphometric characteristics of fruit flies Bactrocera spp. and to generate identification keys using identification key books and the Lucid Key ID website in internship activities at the Agricultural Quarantine Standard Test Centre. Fruit flies species identified during the internship were B. carambolae, B. papayae, B. albistrigata, B. umbrosa, B. caudata, B. cucurbitae, and quarantine fruit flies were B. occipitalis, B. musae, B. correcta, B. zonata. The identification using identification key book are presented in text format, while the identification using the Lucid Key ID program are presented in matrix format. The morphometric measurements that can be used to identify fruit flies are the measurements of the width of lateral postsutural vittae and the width of the mesopleural stripe.

Judul: Keanekaragaman, persebaran dan kunci identifikasi lalat buah (Diptera: Tephritidae) di Kabupaten Bogor dan sekitarnya
Abstrak: Fruit flies are the most important pests for many fruits and vegetables which cause quantitative and qualitative losses of production. Bogor and its surrounding area have many fruit fly host plants. The aim of this research was to investigate the diversity and distribution of fruit flies species and their hosts at Bogor and its surrounding area as well as constructing the identification key for found species. Fruit flies were collected at 119 sampling areas in Bogor and some places of Cianjur, Bekasi and Depok. Collection of samples were using 2 methods: host rearing and trapping. Modification of Lynfield trap and 2 attractants such as metil eugenol (ME) and Cue lure (CL) were used in the trapping. There were 18 species of fruit flies collected from traps and 23 host plants. Distribution, diversity and abundance of fruit flies was influenced by the diversity of host plants.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
