Teknologi gasifikasi tipe downdraft adalah salah satu teknologi untuk mengkonversikan bahan bakar padat atau biomassa padat secara thermokimia dengan temperatur 6000-7000 C menjadi bahan bakar gas mampu bakar dengan kebutuhan udara 20 – 40% Stoikiometri dimana suplai udara masuk dari atas menuju dasar reaktor dan proses gasifikasi terjadi di dasar reaktor. Sampah kota atau ( Municipal Solid Westes) adalah bahan buangan yang terdiri dari bahan organik dan anorganik yang mempunyai nilai kalor sehingga dapat digunakan sebagai bahan bakar. Penelitian ini bertujuan untuk mengetahui performansi dari gasifier tipe dwondraft dengan variasi perlakuan awal bahan bakar kering, pellet, dan briket. Perbedaan perlakuan bahan bakar akan menghasilkan nilai kalor dan karakteristik bahan bakar yang berbeda sehingga nantinya akan didapatkan bahan bakar yang paling efektif. Hasil penelitian menunjukan bahwa efisiensi tertinggi didapatkan pada variasi perlakuan awal bahan bakar sampah kota yang di briketkan yaitu sebesar 61,32% dan FCR tertinggi terjadi pada bahan bakar pellet yaitu 4,61 kg/jam. Gasification type Downdraft technology is one technology to convert thermochemical solid or biomass fuels with temperatures of 6000-7000 C into combustible gas fuels with air requirements of 20 - 40% Stoichiometry where the supply of air enters from above to the reactor base and gasification process occurs at the bottom of the reactor. Municipal solid waste is a waste material consisting of organic and inorganic materials that has a heating value, so that it can be used as fuel of gasification. This study aims to determine the performance of the dwondraft gasifier with variations in the pretreatment of dry MSW, pellets and briquettes. Differences in fuel treatment will produce different heating values ??and fuel characteristics so that the most effective fuel will be found later. The results showed that the highest efficiency was found in the variation of initial treatment municipal solid waste briquettes which was 61,32%, and the highest FCR occurs in pellet fuel which is 4.61 kg / hour.
Abstrak -Madura merupakan salah satu pulau yang terletak di Provinsi Jawa Timur, Indonesia, yang memiliki banyak potensi wisata, namun belum ada sistem yang mewadahi hal tersebut. Akibatnya, wisatawan kesulitan mendapatkan informasi resmi mengenai objek wisata yang terdapat di Madura. Oleh sebab itu, penelitian ini dilakukan dengan tujuan membuat sebuah sistem pendukung keputusan pemilihan objek wisata di Madura agar calon wisatawan lebih mudah untuk memilih objek wisata yang sesuai dengan keinginannya. Berkaitan dengan tujuan tersebut, penelitian ini menerapkan metode logika Fuzzy Tahani sebagai model pendukung keputusan. Model ini digunakan karena peralatan utamanya adalah sebuah hirarki fungsional yang input utamanya adalah kriteria yang telah ditentukan. Hasil penelitian ini diharapkan dapat mempermudah calon wisatawan dalam mengambil keputusan dalam memilih objek wisata di Madura. Dengan menggunakan kriteria pengunjung, jarak dari pusat kota, dan review objek wisata, sistem pendukung keputusan ini mampu memberikan rekomendasi objek wisata pilihan. Berdasarkan pengujian fungsionalitas, diketahui bahwa sistem ini dapat berjalan dengan dengan presentase 100%.
Tourists who travel to a tourism village certainly have different characteristics, motivations, and perceptions. These three things are very important to be identified, because they can become a reference material for the local community and the government related to self-improvements, facilities-improvements, infrastructure, management, and services in Trunyan Tourism Village that can affect the tourist and the returning of them, and are able to provide excellent service in accordance with the tourists expectations.

As a developing country, Indonesia is currently actively developing itself in all its main fields of tourism. Diversity of tourism in Indonesia, one of which is located on Madura Island which has approximately 60 attractions spread across four districts namely Bangkalan, Sampang, Pamekasan and Sumenep. However, the current condition, there are many attractions that are not explored in the outside community so that many tourists do not know which attractions are revised. This study focuses on how to make a decision support system that provides tourist attractions for tourists. The method used is Fuzzy Mamdani which can produce the best decision by determining the Min-Max value and finding the fuzzy value based on its center. This research succeeded in making a system that provides tourist attraction recommendations for tourists by using fuzzy mamdani based on three criteria, namely the number of visitors, the distance of the tourist location to the city center, and the review of visitors on the internet. A post-publication change was made to this article on 20 Apr 2020 as the previously published article was a duplicate.
Pendemi Covid-19 telah memberikan dampak signifikan dalam berbagai sektor kehidupan masyarakat, baik sosial, pendidikan, kesehatan, dan ekonomi. Salah satu pihak yang terimbas adalah pelaku UMKM, menurunnya penghasilan, karena omset penjualan mengalami penurunan drastis. Selain itu permasalahan juga dihadapi oleh dunia pendidikan. Pembelajaran virtual telah memicu berbagai keluhan dari orang tua siswa yang merasa keberatan. Hal tersebut dipengaruhi juga oleh latar belakang pendidikan orang tua yang tidak semuanya mampu mengenyam pendidikan tinggi. Hal ini menyebabkan ketimpangan dalam dunia pendidikan. Melalui pengabdian masyarakat kembali ke desa (back to village) diharapkan dapat menjadi upaya pemberdayaan masyarakat di masa pandemi. Mitra pengabdian adalah masyarakat Kecamatan Tambaksari yang juga megalami imbas di beberapa sector yang disebutkan di atas. Program yang direalisasikan dalam pengabdian masyarakat ini adalah meliputi; digitalisasi dalam manajemen UMKM, pendampingan pembelajarandaring, sosialisasi biopori untuk permasalahan banjir di kawasan setempat, serta sosialisasi taat protokol kesehatan. Masyarakat mitra berkomitmen untuk melanjutkan program ini baik secara kolektif maupun mandiri, sehingga diharapkan program ini mengalami berkelanjutan dan memberikan manfaat lebih besar dalam jangka panjang.
