Judul: Produktivitas jangkrik kalung (Gryllus bimaculatus) umur 21-51 hari yang diberi pakan tambahan tepung kunyit (Curcuma domestica val.)
Abstrak: The aim of this experiment was to investigate the utilization of the turmeric mean feed additive to improve criket productivity and reduce mortality because tumeric meal contains curcuminoid and other active compounds capable inhibiting the growth of pathogens in the digestive tract. The experimental design used completely randomized design, with four threatments and four treatments consisted of four level tumeric meal addition into the ration i.e., 0%; 0.2%; 0.4%; 0.8%.

Judul: Produktivitas Jangkrik Kalung (Gryllus bimaculatus) yang diberi Pakan Konsentrat Buatan Hasil Substitusi Tepung Daun Singkong Muda.
Abstrak: Jangkrik sangat berpotensi untuk dibudidayakan sebagai sumber protein hewani alternatif, karena jangkrik memiliki kandungan protein yang tinggi sebesar 61.58%. Jangkrik kalung memiliki keunggulan dalam laju pertumbuhan dan konversi pakan. Tujuan penelitian ini mengevaluasi performa jangkrik kalung (Gryllus bimaculatus) yang diberi pakan konsentrat buatan hasil substitusi tepung daun singkong muda dengan persentase yang berbeda. Peubah yang diamati diantaranya konsumsi pakan, pertambahan bobot badan, produksi telur, konversi pakan, dan mortalitas. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) 6 taraf perlakuan dan 3 ulangan. Jangkrik yang digunakan sebanyak 2 160 ekor dengan perlakuan K (konsentrat komersial : daun singkong muda) menjadi kontrol, P0 (0% tepung daun singkong muda : 100% subtitusi tepung kedelai), P25 (25% tepung daun singkong muda : 75% subtitusi tepung kedelai), P50 (50% tepung daun singkong muda : 50% subtitusi tepung kedelai), P75 (75% tepung daun singkong muda : 25% subtitusi tepung kedelai), dan P100 (100% tepung daun singkong muda : 0% subtitusi tepung kedelai). Perlakuan P25 nyata lebih tinggi untuk produksi telur. Kombinasi pakan konsentrat buatan hasil substitusi tepung daun singkong muda dengan daun singkong muda segar dapat meningkatkan produktivitas jangkrik kalung.

Judul: Perbandingan SOM dan LVQ pada Identifikasi Citra Wajah dengan Wavelet sebagai Ekstraksi Ciri
Abstrak: Face recognition is one of challenging research topics in computer science because human face is difficult to be modelled. In this research, SOM and LVQ are proposed for frontal face recognition. The purpose is to compare LVQ and SOM based on identification accuracy. Training uses 400 images from 20 different individuals, and the dimension is 180 x 200 pixels. The data are retrieved from University of Essex, UK. Coefficient approximation at Haar wavelet level 6 is used as feature for classification and clustering process. K-fold cross validation with 10-fold is used to divide training and testing data. The experiment is divided into 3 sets, i.e., the experiment using SOM, LVQ, and LVQ initialized by SOM. The highest accuracy achieved by SOM is 97.8974%, while both LVQ and LVQ initialized by SOM achieve 100% accuracy. Based on the accuracy, LVQ proves to be better than SOM for frontal face recognition. This research needs to be improved in order to recognize various poses and changing expressions.
