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: Deforestation or changes in the function from forest to non-forest ecosystems has been playing a role in the change of ecosystem and species in it. Soil fauna is one of is an interesting aspect to be studied. This experiment was conducted in Bungku, District Bajubang, Batanghari Regency, Jambi. Sampling technique using hand sorting method in fourth ecosystem. The fourth ecosystem mentioned is secondary forest (BF), jungle rubber (BJ), oil palm plantations (BO), and rubber plantations (BR). The results found there were 271 individuals are included in 43 familys, 19 orders from 7 class i.e. Insecta, Chilopoda, Collembola, Clitellata, Malacostraca, Arachnida, and Diplopoda, with 2 phylum i.e. Arthropoda and Annelida. Secondary forest is an ecosystem that relatively stable with the value of diversity index H '= 2.50, index of richness DMg = 5.05, and index of evenness E = 0.81. General distribution pattern on the four ecosystems is uniform, with Id value <1. The high diversity of soil macro-fauna was related with soil fertility.

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%.
