Keterbatasan air pada sektor pertanian merupakan salah satu kendala untuk memajukan sektor ini. Untuk bisa mengoptimalkan sumber air yang terbatas perlu perencanaan pola tanam yang baik. Pola tanam merupakan ketetapan mengenai jadwal tanam, jenis tanam, dan luas tanam yang diberlakukan di suatu daerah irigasi. Salah satu cara untuk memaksimalkan penggunaan sumber air pada daerah irigasi adalah dengan cara optimasi. Metode optimasi yang digunakan adalah Program Dinamis, karena sesuai dengan permasalahan perencanaan pola tanam yang dipengaruhi oleh waktu tiap musim tanam selama setahun, sehingga perlu penyelesaian secara bertahap. Hasil perencanaan pola tanam dengan optimasi program dinamis berdasarkan curah hujan, kebutuhan air, dan lama tanam tanaman pangan di Kabupaten Lombok Timur, diperoleh proyeksi keuntungan produksi dibandingkan tanpa optimasi sebesar 20,49%.

Artificial Neural Network and data time series can use for good forecasting method. Artificial Neural Network is a method whose working principle is adapted from mathematical models in humans or biological neural.Neural networks are characterized by; (1)pattern of connections between the neurons(called architecture), (2)determine the weight of the connection (called training or learning), and (3)activation function.The objective of this research is to get the best artificial neural network architecture, compare two method of Backpropagation Artificial Neural Network with Radial Basis Function Artificial Neural Network (RBF).This research is a research using actual data (true experimental). This research was conducted at Wijaya Putra University Surabaya, using secondary data obtained from 2012 to 2016.The result of the research shows that there is a difference between RBF ANN method and the method of Backpropagation ANN, obtained statistical index of RBF ANN, MAE = 0.0074, RMSE = 0.0096, error = 12.6532%. Statistical index of Backpropagation ANN, MAE = 0.2129, RMSE = 0, 2752, error = 13.3217%.

The development of e-commerce is very rapid at this time, with the increasing number of e-commerce making competition in attracting customers and maintaining loyal customers. E-commerce players need to find a strategy for this, one way is advertising on social media, such as; Twitter, Facebook, Instagram, and so on. The purpose of this study was to obtain clustering of tweet data from Twitter using the K-Means method on tweet data from the Blibli Indonesia Twitter account to determine the type of tweet content that was retweeted by followers. The data used is follower tweet data which is pulled from the Twitter account @bliblidotcom. Testing the most optimum number of clusters by finding the largest Silhouette coefficient value. The results obtained that the optimal number of clusters is 10 clusters. From the results of this clustering, the tweet content that Blibli Indonesia consumers like the most is voucher content (cluster 4) and Opportunity series content (cluster 6). Voucher content and opporeno series content as a result of this clustering can be used by Blibli for promos to its consumers.

Peningkatan kunjungan wisatawan ke suatu destinasi wisata, dipengaruhi oleh kepuasan wisatawan waktu berkunjung. Untuk mengetahui suatu destinasi pariwisata sudah sesuai dengan yang diharapkan wisatawan, perlu dilakukan evaluasi terhadap kepuasan wisatawan. Tujuan penelitian ini adalah mendapatkan model klasifikasi yang mempunyai akurasi tinggi dalam melakukan klasifikasi ulasan kepuasan destinasi wisata dan menghasilkan alat bantu untuk pengambilan keputusan dalam pengembagan destinasi wisata. Data yang dipakai pada penelitian ini dimensinya cukup besar, hal ini nantinya membuat waktu komputasi untuk pengklasifikasian makin lama, membuat analisis tidak praktis atau tidak layak, maka reduksi dimensi data diterapkan pada penelitian ini untuk mendapatkan dimensi data yang jauh lebih kecil, namun tetap mempertahankan integritas data asli. Metode yang digunakan untuk pengklasifikasian ulasan kepuasan destinasi wisata adalah kombinasi antara metode Principal Component Analysis (PCA) sebagai metode reduksi dimensi data, dengan tiga metode data mining berikut ini; Support Vector Machine (SVM), Jaringan Saraf Tiruan (JST), dan Decision Trees. Penelitian ini menggunakan data kedua yang diambil dari UCI Machine Learning Repository. Hasil penelitian dengan mengkombinasikan PCA pada ketiga metode memperlihatkan bahwa akurasi klasifikasi lebih baik untuk beberapa metode. Dari ketiga metode yang dipakai, SVM-PCA mempunyai akurasi yang lebih baik dengan 91,50% disusul oleh metode ANN-PCA sebesar 89,46% dan metode Decision-PCA sebesar 88,78%.

Quality control of a product must be maintained, so that consumers feel satisfied in using the products produced. One way that can be done by the industrial world is efficiency in product quality classification. A very good classification method compared to conventional methods, is the Support Vector Machine (SVM) method. The Support Vector Machine method is a supervised learning classification method. The SVM method is an algorithm that works using nonlinear mapping to change the original training data to a higher dimension. The purpose of the research is to obtain a classification model that has high accuracy or small errors in welding quality classification. The target of the researcher is to produce a control device to maintain effective and efficient welding quality. This research is a study that uses actual data, using the second data obtained from March 2018 to May 2018. The results of testing the model using a quadratic function kernel shows the accuracy of 96.2%, and testing using test data shows the results of accuracy 98% using a quadratic function kernel.

The Community Empowerment Program (PPM) this time is a rice cake entrepreneur in the Banyu Urip Wetan Gang 10 area, Kupang Krajan Village, Sawahan District, Surabaya. Lontong entrepreneurs in the region formed the Lontong Entrepreneurs Association consisting of 60 groups of lontong entrepreneurs. The workers who make lontong, use a manual system to cook lontong using simple boilers, so the production capacity is relatively low. Every day, each group has to cook an average of 50 kg of rice to be processed into 620 pcs of lontong. Lontong marketing is still limited, lontong is marketed in West Surabaya and surrounding areas. To overcome these problems, we propose solutions, including: (1) designing and manufacturing lontong cooking equipment by applying Appropriate Technology (TTG) to increase rice cake production. (2) marketing management training to provide insight into expanding lontong marketing. The lontong cooking tool that will be designed consists of a large drum for boiling lontong equipped with a thermostat to measure heat. This tool uses Oil Burner fuel. Oil Burner was chosen because the heat is greater and more even, besides that it is also fuel efficient. The innovation of the lontong cooking equipment is expected to make it easier for entrepreneurs to produce rice cakes and increase their productivity. The marketing management training is expected to provide insight to entrepreneurs to expand marketing to other areas. The results of this service activity include: 1) This Lontong cooking machine can speed up the production process with good quality. 2) The existence of this 620 pcs lontong cooking machine equipped with a heat gauge and a sophisticated combustion tool can speed up partners' productivity time to 2 times faster, previously 8 hours of cooking time became only 4 hours. 3) Lontong produced is of higher quality and more perfect, 4) Marketing management training enables partners to add customers, as well as regulate how marketing works.
