The environmental condition in a large areas often requires the monitoring. For example, in the case of greenhouse were used to cultivation experiments, fertilization experiments, plant resistance experiments, tissue culture experiments, experimental planting of crops in the off-season, and it needs equipment to monitor and control the environmental conditions to suit the characteristics required environment. The extent of land that is must be monitored, making it needs distribute the monitor at some point so that monitoring of environmental conditions can cover the entire desired area. This is the basis for the design of wireless sensor network for monitoring temperature and humidity using the communication module nRF24L01 +. The system consists of hardware for measuring the temperature and humidity at some point in a certain area. The system is divided into several sections that is referred to as nodes. Node in the system is divided into two functions, namely the sensor node and the concentrator node.. There are two the sensor nodes which will serve to data of temperature and humidity in separate areas and transmit data to the concentrator node. The communication between nodes is done using a module nRF24L01+. The design of communication protocol designed to connect between nodes concentrator with a sensor node capable of running properly. This makes the system capable of monitoring temperature and humidity through a web page, so it can be known conditions of temperature and humidity at some point at the maximum range of 93 meters.

Abstrak: Terdapat 21 wisata di Kabupaten Brebes salah satunya adalah wisata Pulau Cemara. Kondisi pandemic mengakibatkan sektor wisata mendapatkan dampak dari kebijakan pemerintah yakni PPKM. Salah satunya adalah desa wisata di desa Sawojajar yakni di pulau cemara mengalami penurunan pengunjung.  Karena kondisi PPKM maka wisata pulau cemara ditutup sementara. Sehingga dengan kondisi tersebut dilakukan pengabdian masyarakat kepada pengelola dan pokdarwis dengan dinas pariwisata dengan 20 peserta.  Tujuan untuk mengenalkan dan pemahaman aplikasi virtual tour yang digunakan sebagai media promosi mengenalkan objek wisata.  Kegiatan PKM ini dilaksanakan pada tanggal 11-12 Januari 2022. Kegiatan PKM ini berupa sosialisasai pemberian materi kaitannya pengenalan dan kegunaan aplikasi virtual tour, dilanjutkan praktik penggunaan dari aplikasi virtual tour dan pendampingan. Hasilnya peserta mengetahui dan mengenal aplikasi virtual tour sebagai media promosi secara lancar dan antusias dengan hasil evaluasi kepada peserta yang mengikuti dengan pengisin quisioner diperoleh sebesar 85% peserta sudah dapat mengenal, memahami dan menggunakan aplikasi tersebut. Abstract: There are 21 tours in Brebes Regency, one of which is Cemara Island tourism. The pandemic condition has resulted in the tourism sector being impacted by the government's policy, namely PPKM. One of them is a tourist village in Sawojajar village, which is an island that has decreased visitors. Due to PPKM conditions, the Cedar Island tour was temporarily closed. So that with these conditions, community service was carried out for managers and Pokdarwis with the tourism service with 20 participants due to PPKM conditions, fir island tourism is temporarily closed. So with these conditions, community service is carried out to managers and Pokdarwis with the tourism office. The purpose is to recognize and understand the virtual tour application that is used as a medium to introduce tourist objects. This PKM activity was carried out on January 11-12, 2022. This PKM activity was in the form of socialization through the provision of application materials and the use of virtual tour applications, followed by the practice of virtual tours and mentoring. The result is that participants know the virtual tour application as a promotional medium smoothly and enthusiastically with the results of the evaluation of participants who take part in the questionnaire, it is obtained that 85% of participants are able to recognize, understand and use the application.

Pemerintah dan pelaku industri pariwisata mengalami permasalahan dalam menentukan prioritas pengembangan suatu destinasi wisata. Karena itu, diperlukan identifikasi objek wisata yang diminati namun banyak mendapat ulasan buruk melalui ulasan dari masyarakat yang tersebar di internet. Penelitian ini bertujuan melakukan analisis sentimen terhadap ulasan objek wisata di Pulau Bali menggunakan Bi-LSTM dan Word2Vec, sehingga diperoleh model terbaik yang dapat digunakan untuk mengidentifikasi objek wisata potensial namun mendapat ulasan buruk. Bi-LSTM merupakan deep learning yang menawarkan akurasi yang lebih baik daripada LSTM biasa. Sedangkan Word2Vec merupakan pretraining yang dipilih karena dapat menangkap makna semantik teks. Penelitian ini menggunakan data ulasan objek wisata di Pulau Bali yang berasal dari situs tripadvisor.com. Penelitian dimulai dari pengumpulan data, perancangan alur program, preprocessing, pretraining Word2Vec, pembagian data uji dan data latih, pelatihan dan pengujian, serta evaluasi penentuan model terbaik. Akurasi terbaik dihasilkan oleh kombisasi Word2Vec terdiri dari CBOW, Hierarchical Softmax, dimensi 200, Bi-LSTM dengan dropout sebesar 0,5 dan learning rate sebesar 0,0001. Kombinasi tersebut menghasilkan akurasi tertinggi dari keseluruhan 108 kombinasi yaitu sebesar 96,86%, precission sebesar 96,53%, Recall sebesar 96,31%, F1 Measure sebesar 96,41%. Akurasi yang baik tersebut membuktikan bahwa kombinasi parameter Bi-LSTM dan Word2Vec cocok digunakan untuk analisis sentimen ulasan objek wisata di Pulau Bali.
