Coffee is an agricultural product that not only functions as a fresh drink, but also comes from an annual plant. Indonesia is known as one of the largest countries in coffee production in the world after Brazil, Vietnam and Colombia in 2017. There are two of the most commonly known varieties of coffee, namely arabica coffee (Coffea arabica) and robusta coffee (Coffea canephora). Due to the similarities between the two types of coffee beans, many people, especially those who are not experienced in the world of coffee, have difficulty telling the difference. Therefore, we need a tool that can help overcome this problem, such as smartengine which can classify arabica and robusta coffee beans. The development of this smartengine follows the Software Developer Life Cycle method using a spiral approach which involves several cycle stages. The first stage involves creating a deep learning model using the Deep Learning Life Cycle method which consists of several steps. In the second stage, deep learning models are provided as a service that can be used by other applications through application programming interfaces (APIs). For smartengine implementation, Google Colab with Keras API and TensorFlow backend is used. This smartengine has the ability to detect coffee beans and also allows the retrain process if needed. Testing is carried out using the blackbox method, where the feature functionality of the smartengine is tested. This research succeeded in developing a smartengine that can detect Arabica and Robusta coffee beans.

The volume of coffee exported from Indonesia between 2010 and 2020 will be reviewed in this study along with the influence of the variables coffee production, land area and exchange rate. In this study the influence of independent factors on dependent factors was assessed using multiple linear regression analysis techniques. The results of the multiple linear regression analysis of this study revealed that Indonesia's coffee exports were negatively affected but not significantly by variables related to coffee production. Indonesian coffee exports were negatively and insignificantly affected by changes in land area. Conversely, the exchange rate (exchange rate) has a positive but also insignificant impact on the volume of coffee exported from Indonesia.

Carangwulung village located in Wonosalam sub-district, Jombang district has the potential of abundant natural resources from plantation products ranging from bananas, durian, salak, to coffee. The large number of products produced in the Segunung Traditional Village is an interesting addition for implementers to focus on increasing promotions and marketing activities that can be carried out independently by the Segunung Traditional Village. The facilities owned by the Segunung Traditional Village ranging from coffee plantations, coffee shops, and springs should be able to make economic potential and tourism education potential that can be offered and make Segunung Traditional Village into a village that has independence in terms of the creative economy. However, the potential possessed by this Traditional Village is still not a tourism product that is well packaged and attractive for tourists who visit in a sustainable manner. This is partly due to the fact that activities have not been documented, village products are not properly published and are not published in an interesting way. Dusun Segunung has several social media options, but partners feel that creative content ideas are very difficult to grow. Starting from how photos, videos of creative products and designs can be managed properly and produced sustainably. The method of implementing community service is in the form of consultation, socialization and assistance on digital marketing strategies, especially in the form of creative videos and social media management. The socialization and mentoring covered material and practice on videography and video editing techniques using simple technology, smartphones. Through this activity, partners are expected to be able to optimize social media in promoting the potential of their villages, events and business products in order to reach a wider market so that business development and progress can ultimately increase the income of the Segunung Traditional Village.
