Judul: Keanekaragaman dan Kelimpahan Spesies Staphylinid (Coleoptera) di Habitat Persawahan Sekitar Bogor
Abstrak: Staphylinid beetles (order Coleoptera) are characterized by elongated and slender body shape, short elytra that covered some segments of the abdomen, and body usually shiny black, brown, or yellow-brown. In the paddy field ecosystem, these beetles are known as predator. This research aimed to measure the diversity and abundance of staphylinid beetles in the paddy field at some areas in Bogor. The research also studied the hemolymph structure of Paederus fuscipes. Collections of beetle were done by using road sampling method in some paddy fields. Observations of hemolymph structure were done by making a blood smear. Staphylinid beetles found in six paddy fields in Bogor were Paederus fuscipes (subfamily Paederinae), Stenus sp. (subfamily Steninae), Hypostenus arachnoides (subfamily Steninae), and Astenus lombokianus (subfamily Paederinae). Diversity of staphylinid species in paddy fields is low. The most dominant species staphylinid at the paddy fields was P. fuscipes. Hemocytes type found in the hemolymph of P. fuscipes beetles were prohemocyte, plasmatocyte, adipohemocyte, and cystocyte.

Judul: Komunitas Staphylinidae (Coleoptera) di Kebun Ubi Jalar
Abstrak: Staphylinidae is a member of order Coleoptera (beetle). This family characterized by elongated slender body, large abdominal section and tapered end of the abdomen, and very short elitra. Most of staphylinids role as predators, saprofag, polifag, and as bioindicators of soil fertility. This research aimed to study the community of staphylinids in the sweet potato fields at Bogor. Observations and collections of beetle were done by using road sampling method. Samples collected were preserved in the ethanol 70% for identification purposes. Environmental factors, i.e. air temperature, humidity, and light intensity were measured during observations of beetles. Result showed that the community of staphylinids found in the sweet potato fields were Paederus fuscipes (subfamili Paederinae), Medon sp. (subfamili Paederinae), and Stenus sp. (subfamili Steninae). The dominant staphylinid species in the sweet potato was P. fuscipes

Judul: Quantum Convolutional Neural Network (QCNN) for Classification Brain Tumor MRI Image
Abstrak: Penelitian ini bertujuan untuk mengembangkan model deteksi tumor otak menggunakan citra MRI dengan metode Quantum Convolutional Neural Network. Data yang digunakan adalah citra MRI otak yang terdiri dari citra tumor otak glioma, meningioma, hipofisis, dan negatif tumor yang dibagi kedalam data latih dan uji dengan rasio 80:20. Selanjutnya data latih dilakukan penyeimbangan dengan teknik oversampling. Dilakukan pengembangan model untuk mendeteksi tumor otak (biner), dan juga model untuk mengklasifikasikan jenis tumor otak (multiclass). Parameter yang digunakan dalam pengembangan model adalah jumlah ukuran filer = 2 dan kedalaman = 4, dengan qubit 4, dan dilatih dengan jumlah epoch sebanyak 10. Data akan diproses dengan metode Quantum Convolutional Neural Network yang terdiri dari lapisan quantum convolution, lapisan flatten, dan lapisan dense. Model multiclass mendapatkan akurasi 52%, setelah data latih diseimbangkan akurasi model meningkat menjadi 62%, sedangkan model biner mendapatkan akurasi 88%, setelah data latih diseimbangkan akurasi model meningkat menjadi 89%.
