Abstract

Some areas in Ponorogo Regency, East Java Province have a natural resource management problem, including flooding during the rainy season and lack of clean water when the dry season arrives. To overcome these problems, Bendo Dam is planned. The planning method begins by determining the location, hydrology, and hydraulic location, which finally obtained information to determine the design of the dam. From the results of the study we found the dimensions of the dam body based on Q1000th, including the dam height of 88 m, the elevation of the dam peak El.224.00, the length of the dam peak 15 m. The building material of the dam body has physical and mechanical properties that meet the existing criteria.  discharge is 649.16 m3 / sec to get the magnitude of the river flow discharge using the Nakayasu HSS method. So that the total dam reservoir is 43,599 x 10 m3. Results Upstream slope stability after the dam has been built The normal state is 2.337> 1.5 (safe) and in an earthquake situation is 1.772> 1.1 (safe). The results of the analysis of the stability of seepage are as follows: 0.0094 m3 / sec < 0.05% < 21799.5 m3 / sec (safe).  Keywords: Main Dam Planning, Urugan Type Dam, Bendo Dam.

Abstract

The emergence of the issue of childfree has become a trending topic on Twitter since the beginning of 2020 until now, which has given rise to many positive and negative opinions from various groups, especially on Twitter social media. This sentiment analysis research aims to determine the responses given regarding childfree in the form of positive, neutral or negative opinions by collecting Twitter data. The number of datasets used is 700 data, divided into 630 training data and 70 test data. This research uses the Naïve Bayes algorithm classification and confusion matrix as a performance evaluation of the system being built. The test results show an accuracy value of 64.29%, precision of 68.25%, recall of 64.29% and fi-score of 55.69%.

Abstract

Artikel ini menyajikan bagaimana pendampingan terhadap kelompok tani dalam memanfaatkan limbah rumah tangga seperti air cucian beras sebagai bahan untuk pembuatan pupuk cair (POC). Air cucian beras atau air leri mengandung vitamin seperti niacin, riboflavin, piridoksin da thiamin, serta mineral seperti Ca, Mg dan Fe yang diperlukan untuk pertumbuhan jamur. Dimana penggunaan limbah air cucian beras sangat efektif untuk penyuburan tanaman karena bahan-bahannya yang sangat mudah didapatkan dan tergolong murah. Salah satu diadakan pendampingan ini bertujuan untuk memberikan pengetahuan mengenai kegunaan limbah air cucian beras menjadi Pupuk Organik Cair (POC) kepada kelompok tani desa Suren Kecamatan Ledokombo, Kabupaten Jember. Cara pembuatan pupuk organik cair pertama siapkan limbah cucian air beras, E4, dan tets tebu, dan juga jerigen sebagai tempat pembuatan pupuk berlangsung. Selanjutnya campurkan dulu limbah cucian beras tersebut dengan molase, kemudian campurkan dengan E4 lalu di masukkan ke dalam jerigen dan diamkan selama dua minggu untukt di fermentasikan. Adapun tujuan lainnya dalam proses pembuatan pupuk organik cair ini yaitu, diharapkan dapat mengurangi sampah organik rumah tangga. Kemudian metode yang digunakan dalam melakukan pengabdian masyarakat ini yaitu memberikan suatu penyuluhan atau sosialisasi dan juga bentuk praktik untuk pembuatan pupuk organik cair.
