Judul: Rancang Bangun Sistem Smart grading Susu Segar Berbasis Internet of Things
Abstrak: Kualitas susu segar merupakan faktor utama dalam menentukan harga susu. Peternak susu menjual susu segar dengan kualitas yang berbeda-beda. Hal yang mempengaruhi kualitas ini adalah kondisi hewan dan lingkungan. Faktor lain seperti pemantauan suhu penyimpanan susu segar masih menggunakan metode konvensional oleh karena itu, tujuan dari penelitian ini adalah menentukan grade susu segar dan monitoring suhu dan kelembaban secara real time. Salah satu alternatif baru yang dapat digunakan untuk mengatasi permasalahan ini adalah memanfaatkan teknologi terbaru, seperti Internet of Things (IoT). Pertama, analisis kebutuhan sistem yang berbasis IoT untuk mengembangkan prototipe smart grading susu segar. Pemodelan sistem smart grading susu segar berbasis rekayasa sistem. Kedua, menerapkan teknik pembelajaran mesin yaitu Jaringan Saraf Tiruan (JST), digunakan untuk klasifikasi grade susu segar berdasarkan kualitas. Prototipe sistem dikembangkan menggunakan alat sensor DHT22 dan Node-MCU ESP-8266, yang mampu menampilkan fitur secara real time. Alat cerdas ini menampilkan suhu dan kelembaban untuk menjaga kualitas susu segar selama proses pre-produksi. Atribut yang menentukan sistem smart grading adalah suhu, kelembaban, jumlah mikroba, berat jenis, dan total lemak. Model JST mampu mengklasifikasi sistem smart grading dengan akurasi 92.59%. Penelitian ini menghasilkan model yang mampu monitoring suhu dan kelembaban secara real time dan menampilkan grade susu segar tiap peternak. Rancang bangun sistem smart grading susu segar membantu dalam penentuan harga jual susu segar tiap peternak.

Judul: Sistem Intelijen Penilaian dan Prediksi Kualitas Susu Pasteurisasi (Studi Kasus pada PT . Industri Susu Alam Murni Bandung)
Abstrak: The aim of this research is developing an intelligent system for assessment and prediction of pasteurized milk quality. The system is implemented by integrated expert systems and Artificial Neural Network (ANN). This system is designed and developed by Matlab 6.5 and called SINKUAL-SP. The logical strategy model used is “Forward Chaining” and the tracing method used is “Best First Search” method. The method of Certainty Factor (CF) is used for handling uncertainty. Model Based Management system consist of five model : quality of fresh milk model, quality of process model, quality packaging and storage model, statistical process control model and prediction model by neural network. Multilayer system is used for the neural network architecture with one input layer, one hidden layer dan one output layer. The activation function is Sigmoid Bipolar activation function which gives the best performance network with learning rate 0.005 and momentum 0.9 together with RMSE, MSE and SSE as criterion error. The validation for neural network indicates the conformity between output of neural network and output of goal with value of RMSE 0.009959, MSE 0.00999 and SSE 0.009950. Decision for acceptance fresh milk and pasteurized of milk is implemented by acceptance grade which gives control quality process is easier than previously system. Based on the grade acceptance, the management of industry can take decision and action allow with a significant output of grade. In the research implementation stage, the data, gained in the company of “PT. ISAM” in April 2005, brings a significant output of research regarding quality of fresh milk such as the grade B, grade A for quality of process, and grade B for quality packaging and storage. This system gives a suggestion for user to improve the quality of pasteurized milk. Based on the outputs from the systems used, highly priority strategy quality system reconstruction, with 0.236 as weighting value. The quality improvement system upon the results of research is seemed to be a way of improving the quality of milk in process of pasteurization.

Judul: Distribution and Diversity of Ectoparasite Mites on Geckos in Indonesia
Abstrak: Data on the diversity and dispersal of parasitic mites on house geckos in Indonesia are very scarce. In this work, the distribution and diversity of mites living on three species of house geckos, namely Cosymbotus platyurus, Hemidactylus frenatus, and H. garnotii collected throughout Indonesia, has been elaborated. Geckos and mites were captured and immediately preserved in 70% ethanol. Whole mount of the mites was prepared by clearing in lactophenol followed by mounting on polyvinyl lactophenol solutions. The SEM preparation was conducted to examine the detail morphological characters of the mites. The results showed that among 448 individuals of geckos, 221 geckos were infected by Geckobia mites. Prevalences of C. platyurus, H. frenatus, and H. garnotii infested by mites were 14.8%, 50.69%, and 79.6%, respectively. Three different spesies of Geckobia (G1, G2, and G3) could be differentiated; and based on similarities of their morphological characters to ones described in published literatures, Geckobia G2 is Geckobia glebosum and Geckobia G3 is Geckobia bataviensis while G1 could not be identified to the species level. The highest mean intensity of Geckobia G1 infestation was found on H. garnotii (I=7.0), G. glebosum infestation on H. frenatus (I=3.5), and G. bataviensis infestation on H. garnotii (I=11.8). In general, C. platyurus was infested by the least number of mites. Geckobia G1 were found living on the skin folds on the claws, G. glebosum were found mainly on the body and thigh, and G. bataviensis were found on almost all parts of the host’s body. Geckobia mites are distributed randomly throughout Indonesian Archipelago, following the pattern of distribution of their hosts. So it is concluded that Geckobia G1, G. glebosum, and G. bataviensis are sympatric.
