Judul: Perbandingan Keanekaragaman Semut (Hymenoptera: Formicidae) Pada Empat Tipe Ekosistem yang Berbeda
Abstrak: Deforestation or transformation of forest function to non-forest has been playing a role in the changes of ecosystem and species in it. Insect as one of the living fauna that live in the forest is an interesting aspect to be studied, especially ants. This experiment was conducted in Bungku, Bajubang District , Batanghari Regency, Jambi. Sampling technique using pitfall traps in four ecosystem. The four ecosystem mentioned is secondary forest, oil palm plantations, rubber plantations, and jungle rubber. The results found there were 5 484 individuals of 50 ant morphospecies, 33 genera of 6 subfamily i.e. Formicinae, Myrmicinae, Ponerinae, Dolichodorinae, Pseudomyrmicinae, and Dolichorinae. Secondary forest is an ecosystem that relatively stable with the value of diversity index H '= 2.76, index of richness DMg = 4.96, and index of evenness E = 0.70. The ant communities depend on environment factor of each ecosystem.

Abstrak: Conversion of tropical forests, mainly to agricultural area is the most important driver of tropical biodiversity loss. As dominant species in lowland forests, ant species diversity is prone to decline sharply due to forest transformation. This research was conducted to investigate the diversity of ants and its role in different land use. Ecological research was conducted in four types of land-use i.e. forest, jungle rubber, oil palm plantation and rubber plantation, located within two landscapes i.e. Bukit Duabelas National Park and Harapan Forest in Jambi, Indonesia. Each type of land use, four plots were selected for ant sampling. Ants were collected using baiting methods, combination between tuna and sugar. Ant diversity in Harapan Forest higher than in TNBD. In total, 66 species of ants belonging to 4 subfamilies and 20 genera were recorded from both area of Bukit Duabelas and Harapan. Surprisingly, the highest number of ant species was found in oil palm plantation. In addition, the compositions of ants based on its role showed differ among land-use types. It indicates that land-use change drive ant species composition.

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%.
