Judul: Deep Neural Network untuk Klasifikasi Formula Jamu Berdasarkan Metabolit
Abstrak: Jamu adalah bahan atau ramuan bahan yang berupa bahan tumbuhan, bahan hewan, bahan mineral, sediaan sarian atau campuran dari bahan tersebut, yang secara turun temurun telah digunakan untuk pengobatan berdasarkan pengalaman. Tumbuhan-tumbuhan tersebut di dalamnya mengandung senyawa atau metabolit. Penelitian ini bertujuan menjelaskan prosedur klasifikasi formula jamu berdasarkan metabolit menggunakan metode Deep Neural Network (DNN). DNN dipilih karena kemampuannya untuk mengekstraksi dan mempelajari fitur secara otomatis, terutama untuk data kompleks dan berdimensi tinggi yang tidak mudah dipahami. Nilai akurasi tertinggi yaitu sebesar 86.57% didapat dari hasil klasifikasi DNN dengan menggunakan tuning trial-error fungsi aktivasi RectifierWithDropout pada dataset yang dilakukan praproses menggunakan SVM dengan kernel RBF. Sedangkan nilai akurasi tertinggi untuk klasifikasi Random Forest sebesar 81.75%.

Judul: Prediksi Khasiat Jamu Berdasarkan Metabolit dan Identifikasi Metabolit Penting Menggunakan Gradient Boosting Machine dan Deep Neural Network.
Abstrak: Jamu adalah sistem pengobatan tradisional Indonesia yang digunakan luas untuk memelihara kesehatan dan menyembuhkan penyakit. Untuk menjaga kualitas dan keamanan jamu, diperlukan pendekatan ilmiah, salah satunya dengan kajian metabolomik yang memanfaatkan data berdimensi tinggi serta machine learning. Pada penelitian ini dilakukan prediksi khasiat jamu berdasarkan kandungan metabolit menggunakan classifier Gradient Boosting Machine (GBM) dan Deep Neural Network (DNN) dan identifikasi metabolit yang penting pada setiap kelas khasiat. Data jamu di-filter dengan tiga jenis kernel SVM menghasilkan tiga dataset berbeda: JamuL, JamuP, dan JamuR. Akurasi tertinggi untuk classifier DNN sebesar 0.907 dicapai menggunakan data JamuL dan classifier GBM sebesar 0.903 dicapai menggunakan data JamuR. Pada model terbaik tiap classifier diidentifikasi metabolit penting dengan metode interpretasi model Shapley Additive Explanation (SHAP). Dari 85 metabolit penting tiap kelas khasiat yang diidentifikasi dari model GBM dan DNN, terdapat 20 yang dapat divalidasi oleh studi literatur. Metabolit yang belum diketahui memiliki hubungan dengan kelas khasiat tertentu dapat menjadi kandidat khasiat yang dapat diteliti lebih lanjut.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
