Abstract

People's activities that often upload photos of food before eating are common in popular social media, such as Facebook, Instagram, Twitter, and Pinterest. The food image data circulating on social media can be used for business purposes, such as analyzing customer behavior patterns. However, not all of the uploaded images are food images, so that before the analysis is carried out, it is necessary to do a classification task between food images and non-food images. Therefore, the researcher proposes automatic food image classification using transfer learning method using the Residual Network model version of 18 (ResNet-18). Residual Network model is used because it has a residual connection mechanism to solve the vanishing gradient problem. In addition, transfer learning was chosen because this method leverages the features and weights that have been generated in the previous training process on large and more general data (Imagenet) and thus reduce computation time and increase accuracy. The test was carried out by comparing the capabilities of the ResNet18 model with AlexNet. In addition, the fine tuning and freeze layer methods used to improve the quality of the model were also carried out in this study. In the experiment, the data set was divided into 3,000 images for training data and 1,000 images for test data, while the evaluation used was correctness accuracy. The results obtained in the ResNet18 model, namely the fine tuning training method, produced an accuracy value of 0.981 while the freeze layer resulted in the best accuracy value of 0.988. The AlexNet model that uses the fine tuning training method produces an accuracy value of 0.970 while the freeze layer produces the best accuracy value of 0.978. It can be concluded that the mechanism with the best accuracy is found in the RestNet18 architecture using the freeze layer 1-3 with an accuracy of 0.988.

Abstract

Toko Bangunan Barokah (TB. Barokah) yang berada di Singosari, Malang, Jawa Timur adalah salah satu toko yang menjual bahan bangunan. Beberapa barang yang dijual adalah semen putih dan semen hitam. Jumlah penjualan semen setiap bulan sangat beragam dan fluktuatif. Semen hitam menempati angka sangat tinggi dibandingkan semen hitam pada grafik penjualan setiap bulannya. Begitu juga dengan semen hitam merek Bosowa, semen putih merek Gresik dan merek Tiga Roda meskipun permintaan kecil, tetapi masih terjadi pergerakan jumlah penjualannya. Jumlah permintaan yang sangat fluktuatif menjadikan jumlah persediaan produk yang disiapkan tidak pasti, yang dipengaruhi oleh jumlah jenis dan merek, sehingga manajemen persediaan produk kesulitan dalam penyediaannya. Penelitian ini bertujuan untuk meramal jumlah semen yang terjual di bulan berikutnya, serta untuk mengetahui kinerja antara kedua metode Double Exponential Smoothing (DES) dan Simple Moving Average (SMA) untuk melakukan forecasting hasil penjualan semen pada TB. Barokah. Metode SMA mampu melakukan peramalan dengan data permintaan atau penjualan yang stabil/konstan. Sedangkan metode DES mampu dan dapat memberikan nilai pada bobot secara bertingkat dengan data up to date. DES mampu melakukan peramalan penjualan semen tiap bulan dengan nilai rata-rata percentange error (PE) 0,14%, sedangkan SMA dengan nilai rata-rata PE 1,35%.  Berdasarkan hasil pengujian menggunakan data dari TB. Barokah didapatkan bahwa metode yang paling efektif adalah DES karena memiliki nilai PE lebih kecil dibandingkan dengan SMA.

Abstract

ABSTRAK Routing merupakan proses mengirim data dari satu network ke network lain. Dengan dynamic routing maka mekanisme routing dilakukan secara dinamis dengan menentukan jarak terpendek secara cepat dan akurat antara peralatan pengirim dan penerima. Open Shortest Path First (OSPF) merupakan salah satu protokol dynamic routing yang menggunakan algoritma link-state untuk membangun dan menghitung jalur terpendek ke semua tujuan yang diketahui. OSPF mendistribusikan informasi routing antara router-router autonomous system (AS). OSPF memiliki titik berat pada kinerja processor, kebutuhan memori dan konsumsi bandwidth. Oleh karena itu perlu mengoptimalkan kinerja protokol routing OSPF terutama masalah pengaruh bandwith dengan menentukan model dan area jaringan routing OSPF. Kata kunci : routing, rynamic routing, OSPF ABSTRACT Data sending processes from one to the other networks is called to be Routing. Using the dynamic routing, the routing mechanism is dynamically done by swiftly and accurately determining the shortest route between sender and receiver. One of the dynamic routing protocols is the Open shortest path first (OSPF) using link-state algorithm to build and count the shortest route to the all known destination. OSPF distributes routing information between system autonomous routers (AS). The focus of OSPF is in the processor activity, memory needs and bandwidth consumption.  There are needs to optimize OSPF routing protocol activity by determining OSPF routing network area and model especially to the bandwidth influence. Key words: routing, dynamic routing, OSPF
