    Unified Chew-Mandelstam SAID analysis of pion photoproduction data

    Full text link
    A unified description of single-pion photoproduction data, together with pion- and eta-hadroproduction data, has been achieved in a Chew-Mandelstam parametrization which is consistent with unitarity at the two-body level. Energy-dependent and single-energy partial wave analyses of pion photoproduction data have been performed and compared to previous SAID fits and multipoles from the Mainz and Bonn-Gatchina groups.Comment: 11 pages, 9 figures, and 2 table

    Sistem Informasi Peramalan Harga Pangan dengan Menggunakan Metode Naïve Bayes di Kota Makassar

    Full text link
    Dinas Perdagangan Kota Makassar merupakan lembaga yang bertanggung jawab dalam merilis informasi harga pangan di Kota Makassar secara langsung. Informasi tersebut disajikan dalam bentuk selebaran. Penelitian ini bertujuan adalah untuk merancang dan menerapkan Sistem sistem informasi Peramalan Harga Komoditas Pangan Menggunakan Algoritma Naive Bayes untuk memprediksi harga pangan di Kota Makassar. Desain penelitian yang digunakan adalah UML yang didesain secara terstruktur yang terdiri dari rancangan model use case diagram, activity diagram, sequence diagram dan class diagram. Bahasa pemrograman menggunakan PHP, javascript, dan MySql untuk pengolahan database. Dalam penelitian ini pengumpulan data diperoleh melalui observasi, wawancara dan dokumentasi. Hasil dari penelitian ini adalah sistem berbasis website yang menyediakan informasi harga komoditas dan sistem pendukung keputusan prediksi harga komoditas pangan di Kota Makassar. Sistem tersebut membantu instansi dalam menyediakan informasi dan pelaporan

    In this paper, we investigated the conditions required to ensure human survival on Venus, along with the effects of the Venusian climate on the astronauts and the spacecraft. By considering thermal conductivity and Young's modulus, we calculated that 78 MW of power would be required to maintain a room temperature environment within the spacecraft, a human would last 47.5 s before succumbing to the high temperatures, and that Tungsten would be required to prevent a spacecraft from breaking due to thermal expansion

    Purpose: This research aims to provide recommendations for planting season based on predictions of rainfall, air temperature, and wind speed based on the website.Design/methodology/approach: This study implemented the Double exponential smoothing to predict rainfall, air temperature, and monthly wind speed one year in the future using past data.Findings/result: This study has succeeded in providing recommendations for planting season. Based on the results of the accuracy calculation between the prediction results and the actual data using the Mean Absolute Percetage Error (MAPE), each has a forecast error value of 30.69% for rainfall, 0.63% air temperature, and 5.89% wind speed. Originality/value/state of the art: Research related to the application of Double exponential smoothing to determine the planting period. Based on the results of the accuracy calculation between the prediction results and the actual data using Mean Absolute Percetage Error (MAPE), this has never been done in previous studies

    Sistem Pendukung Keputusan Pendistribusian Air Bersih Menggunakan Mobil Tangki pada PDAM Kota Makassar dengan Menggunakan Metode TOPSIS

    Get PDF
    PDAM Kota Makassar merupakan perusahaan daerah yang bertugas dalam  pengelolaan dan pemenuhan kebutuhan air bersih bagi masyarakat di kota Makassar. Penyaluran air bersih yang dilakukan PDAM Kota Makassar masih belum mencakup keseluruhan wilayah Kota Makassar,  ini disebabkan karena beberapa hal salah satu diantaranya debit air yang berkurang. Untuk mengatasi hal tersebut pemerintah kota Makassar melalui PDAM, melakukan pendistribusian air dengan cara pengantaran langsung ke rumah warga menggunakan mobil tangki. Proses penyaluran air PDAM mengalami kesulitan untuk menentukan daerah atau warga mana saja yang mendapatkan prioritas pengantaran air bersih, karena armada yang digunakan masih kurang. Mengatasi hal tersebut maka dibuat sebuah Sistem Pendukung Keputusan Pendistribusian Air Bersih, untuk memudahkan prioritas pengantaran air bersih. Metode penelitian melalui empat tahapan yaitu, pengenalan masalah, pengumpulan data, perancangan sistem, dan pengujian sistem, sedangkan metode yang digunakan adalah metode Topsis yang menggunakan 4 kriteria yakni; Peruntukkan, Jarak, Jumlah Kubik yang dipesan, dan Prediksi Jumlah pemakai. Peneliti memilih metode TOPSIS agar penentuan alternatif antara jarak ideal positif dan negatif lebih optimal. Hasil dari penelitian ini merupakan sistem pendukung keputusan pendistribusian air bersih PDAM  yang berbasis web yang memudahkan penentuan prioritas  penyaluran air bersih kepada masyarakat. AbstractPDAM Makassar City is a regional company assigned to manage the fulfillment of clean water needs for citizens of Makassar City. Currently, the distribution of clean water still has not fully covered the entire area of Makassar City.  The major causes of this situation is a dramatic decrease of the water debit in certain time. To overcome this problem, the government of Makassar city through PDAM, distributes water by direct delivery to the resident's houses using tank trucks.  The process of channeling water from PDAM has difficulty in determining priority areas of delivery due to lack of the fleet. This research consists of  four stages, namely: recognition of problems, data collection, system design, and system testing. While for the algorithm using the TOPSIS method that incorporate four criterias including the allotment, distance, amount of cubic, as well as predicted number of users. The  TOPSIS method is chosen since the determination between the positive and negative ideal distances is more optimal. The results of this study is a web-based decision support system for clean water distribution of PDAM that helps to determine the priority of clean water distribution to the community in Makassar
