Judul: Aktivitas Perilaku Meghimatium bilineatum dan Deroceras laeve pada daun bawang (Allium fistulotum) di Kawasan Pertanian Agropolitan Cipanas.
Abstrak: Meghimatium bilineatum and Deroceras laeve are gastropod without shells. These animals live as pests in horticultural commodities (such as Allium fistulotum). This study aims to determine the behavioural activities of the M. bilineatum and D. laeve on Allium fistulotum in Agropolitan Agricultural Regions, Cipanas. The observed behavioural activities are their emerging, locomotion, feeding, returning to their hideout and mating. Observations were carried out from 18:00 in the twilight until 6:00 in the morning for 20 days. The results of this study indicated that the M. bilineatum’s behavioural emerging activity was peaked at 19:00, locomotion activity peaked at 19:00 and 02:00, feeding activity peaked at 23:00 pm, and returning to their hideout peaked at 03:00, while mating activity was not too often found. For D. laeve’s emerging activity, locomotion activity, feeding activity, returning to their hideout peaked at 18:00, at 18:00 and 04:00, at 22:00, and respectively, at 05.00. Meanwhile mating activity of this slug is not too obvious.

Judul: Potensi Beberapa Jenis Tanaman sebagai Atraktan dalam Pengendalian Hayati Hama Keong Mas (Pomacea canaliculata L.).
Abstrak: Keong mas (Pomacea canaliculata L.) adalah hewan invasif yang menjadi hama padi di areal persawahan. Pengendalian keong mas dapat dilakukan secara alami menggunakan tanaman sebagai atraktan. Penelitian ini bertujuan mengeksplorasi jenis tanaman dan waktu pengamatan yang membuat keong mas paling banyak mendekati tanaman. Penelitian dilakukan pada kolam berukuran 1.8 m x 1.8 m yang dibagi menjadi 9 blok. Sebanyak 200 individu keong mas berukuran kecil dan besar diletakkan pada blok ke-5 (di tengah), kemudian delapan blok di sekitarnya diletakkan satu jenis tanaman yang berbeda. Perpindahan keong mas mendekati jenis tanaman yang disukai diamati setiap 1 jam dari pukul 06.00 - 18.00 WIB. Pengamatan diulang sebanyak lima kali pada lima hari yang berbeda. Hasil pengamatan menunjukkan bahwa keong mas kecil paling banyak berpindah mendekati daun talas belitung (Xanthosoma sagittifolium) (7.9 ± 4.0 individu), sedangkan keong mas besar pada daun pepaya (Carica papaya) (7.1 ± 4.4 individu). Kedua tanaman tersebut yang paling berpotensi dijadikan atraktan. Jumlah keong mas pada tanaman ditemukan paling banyak pada pukul 18.00 WIB. Kata kunci: ABSTRACT LISDASARI PRIANDHINI. The Potenty of Several Plant Types as Attractants in Biological Control of Golden Apple Snail (Pomacea canaliculata L.). Supervised by TRI HERU WIDARTO and TATIK CHIKMAWATI. Golden apple snail (Pomacea canaliculata L.) is an invasive animal that becomes a destructive pest in rice fields. Controlling this snails can be done naturally using plants as attractants. This study aims to explore species plants and the duration of time needed that make the largest number of snails attracted to the plants. The study was conducted on a 1.8 m x 1.8 m pool divided into 9 blocks. A total of 200 small and large snails are placed in the 5th block (in the middle), then eight different blocks surrounding it were filled with one species of plant. The movement of snails toward a species of plant was observed every 1 hour from 06.00 AM to 06.00 PM. This trial was repeated five times in five consecutive days. The observations showed that most small snails moved towards belitung taro leaves (Xanthosoma sagittifolium) (7.9 ± 4.0 individu), while most large snails moved towards papaya leaves (Carica papaya) (7.1 ± 4.4 individu). Those two types of plants are the most potentially used as attractants. In addition, the largest number of snails found in the plants occurs at 18.00 WIB.

Judul: Implementasi Pengenalan Suara dalam Pencarian Ayat-Ayat al-Quran Menggunakan MFCC dan Codebook
Abstrak: Pencarian teks ayat-ayat al-Quran tidaklah mudah dikarenakan dibutuhkan keahlian khusus dalam pengetahuan bahasa Arab. Oleh karena itu, dibuatlah sebuah sistem pencarian teks ayat-ayat al-Quran dengan bantuan transkripsi suara agar mempermudah pencarian ayat-ayat al-Quran. Dengan menggunakan MFCC sebagai ekstraksi ciri, suara diubah menjadi sebuah data vektor yang dapat dicirikan dan dijadikan sebuah codebook. Penelitian ini bertujuan untuk mengimplementasikan pengenalan suara ke dalam sebuah sistem pencarian teks al-Quran. Terdapat 4 potongan ayat Al-Quran yang akan diidentifikasi ke dalam ayat-ayat yang mengandung potongan ayat terebut. Penelitian ini berhasil menghasilkan sebuah sistem yang dapat mendeteksi potongan ayat al-Quran pada sebuah ayat dengan akurasi sebesar 85%
