Abstract

The sea is one of the sources of wealth in Indonesia. Damage to and on the sea greatly impacts marine ecosystems and the livelihoods of people on the coast. Oil spills are the main source of marine pollution. Several ways of handling oil spills are carried out utilizing mechanical removal, using sorbents, and using dispersants. This countermeasure is carried out in offshore sea areas so that large ships and human resources are needed are many and qualified technologies needed that can help handle oil spills can be done remotely by designing a wireless system that can control an unmanned waste oil cleaning robot. This study aims to get the results of Bluetooth module as a wireless control system for waste oil cleaning robots and to implement Bluetooth module for this robot control system. The design of this robot control system utilizes the HC06 Bluetooth module as a connection to connect to the smartphone and uses the Arduino Uno R3 block to enter algorithm programming to be able to drive a waste oil cleaning robot. Bluetooth module testing is carried out with treatment with and without obstacles with a range of 1-15 m. Tests were also carried out to move the robot to go forward, backward, and turn right, and left. The control of the waste oil cleaning robot can be properly connected at all ranges with unhindered treatment at all ranges. While the treatment with obstacles can only be connected up to a distance of 9 m. The performance of the cleaning robot to move forward, backward, turning right, and left with a 100% success rate. Based on the test data, it can be concluded that the Bluetooth module HC06 and Arduino Uno R3 can be applied to control robots cleaning waste oil.

Abstract

Desa Pagaruyung merupakan sentral perkebunan dan pengolahan yang dikenal sebagai “Kampung Nanas), terletak di Kabupaten Kampar. Beberapa UMKM di Desa Pagaruyung telah menghasilkam produk olahan nanas berupa keripik, sirup dan sale nanas. Meningkatnya permintaan akan produk olahan nanas menyebabkan meningkatnya jumlah limbah nanas berupa kulit dan bonggol yang tidak termanfaatkan. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pengetahuan peserta pelatihan dalam memanfaatkan kulit dan bonggol nanas menjadi produk bernilai ekonomi dan mendorong terwujudnya pertanian berkelanjutan. Metode yang digunakan adalah Participatory Rural Appraisal (PRS) yang memungkinkan mitra berpartisipasi aktif dalam kegiatan sejak identifikasi masalah sampai akhir kegiatan. Tahapan dalam pengabdian ini meliputi: tahap penyuluhan pembuatan tepache dan evaluasi kebermanfaatan kegiatan. Berdasarkan hasil kuesioner menununjukkan terjadi peningkatan pengetahuan peserta berkisar antar 66,67%-100% terhadap proses pembuatan minuman tepache, manfaat tepache terhadap kesehatan dan kemasan yang cocok untuk produk tepache.

Abstract

Coffee Shop XYZ is a coffee shop located in Lampung that provides a space for people from all walks of life to meet and gather with friends. This shop focuses on service quality because service is one of the factors that influence customer satisfaction. This study focuses on the services provided at the coffee shop using the Quality Function Deployment (QFD) method integrated with the Importance-Performance Analysis (IPA) method. This study integrates the IPA and QFD approaches as strategic tools for coffee shop management to transform findings regarding service weaknesses into concrete, systematic, and measurable technical action plans. The result of this QFD development is a House of Quality (HoQ), which contains information regarding the design and development of products or services aimed at identifying value gaps in customer satisfaction levels through the creation of a Planning Matrix within the QFD method. This study involved 100 respondents, each of whom was a general coffee shop consumer and a consumer of Coffee Shop XYZ. The results of this study indicate that there are 10 attributes that do not yet meet consumer expectations because they still have negative values, and a priority order for improvements was derived from the technical responses of Coffee Shop XYZ to enhance consumer satisfaction, particularly regarding service quality, as it has a strong relationship with consumer needs; thus, it is expected that these attributes will make a significant contribution.
