Abstract

Prediction is a process for estimating how many needs will be in the future. This study aims to predict the amount of rice production by province. The role of the agricultural sector in the national economy is very important and strategic. The rice plant (Oryza sativa L.) is an important food crop which is a staple food for more than half of the world's population because it contains nutrients that the body needs. Domestic production made the government still carry out the food import policy even though a number of regions claimed to have surplus rice production. This causes a lot of the country's foreign exchange to be used because of the operational costs of rice imports. By using Artificial Neural Networks and backpropagation algorithms, an architectural model will be sought to predict the amount of rice production by province in order to determine the steps to meet domestic rice demand based on the amount of rice consumption of the community. This study uses 6 input variables, namely data from 2010 to 2016 with 1 target, the data of 2017. Using 5 architectural models to test the data to be used for prediction, namely the 6-4-1 model, 6-8-1 , 6-16-1, 6-2-3-1 and 6-3-2-1. Obtained the results of the best architectural model is 6-8-1 architectural model with truth accuracy of 100%, the number of epochs 145 and MSE is 0.010250963.

Abstract

Education and technology develops very rapidly and becomes a positive thing if both can be used together. Education 3.0 method is a teaching method where students can use technology to find references and discuss them with lecturers and other students. The WhatsApp application will be used as a learning media to study English as Foreign Language (EFL) along with the Education 3.0 method. This study aims to find out how important the use of WhatsApp media is and how far its function is based on students' perceptions. Data was obtained from a survey conducted on 90 respondent of EFL study participants. A pilot study was also conducted on 30 respondents to find out the reliability of the instrument in this study. A quantitative data were collected and accumulates total sample together with the percentages of returns. Data summary is used to identify the usefulness of the learning tool. The results of the study show that WhatsApp can significantly help students in learning EFL, but the activeness of students in participating in online lessons must also be considered so that WhatsApp can be truly effective in implementing the Education 3.0 method.

Abstract

Dalam upaya meningkatkan kebutuhan hidup, manusia memerlukan sumber daya alam untuk meningkatkan kebutuhan terutama lahan. Lahan dimanfaatkan untuk beberapa keperluan salah satunya adalah untuk bermukim atau sebagai tempat tinggal. Manfaat lain dari lahan adalah sebagai media untuk meningkatkan pendapatan dan meningkatkan kebutuhan hidup, sebagai salah satu contoh adalah untuk peternakan dan pertanian. Prospek bisnis ini cukup bagus karena permintaan lele semakin meningkat seiring dengan bertambahnya penduduk Indonesia dan semakin menjamurnya usaha warung makan yang menyajikan menu utama ikan lele atau masakan ikan lele. Dengan pakan ikan hasil olahan sendiri atau mandiri keuntungan yang didapat lebih besar dari pada dengan menggunakan pakan ikan pabrikan. Tetapi keuntungan dari pakan ikan tidak semaksimal yang diperkirakan karena disebabkan beberapa faktor yang mempengaruhi. Salah satu faktor yang mempengaruhi adalah cuaca, karena pada saat proses pembuatan pakan ikan lele, keadaan pakan ikan lele sedikit lembab atau belum kering total, hal ini yang menyebabkan kualitas pakan ikan lele menjadi tidak baik, dikarenakan pada akhir pembuatan pakan ikan lele harus dijemur terlebih dahulu kemudian dapat disimpan dan diproduksi ke masyarakat luas. Peneliti akan menerapkan kecerdasan buatan menggunakan logika fuzzy untuk sistem yang akan diterapkan kedalam mesin pengering atau oven.

Abstract

Medan city is one of the largest cities in Indonesia which has a variety of tourist objects and is also known as a culinary paradise that can be used as a culinary tourist destination for people in Indonesia. But the absence of a forum that provides information about businesses whose products have a halal label makes Muslim communities very careful in using or consuming the products they buy. As for the development stage for data collection in building a geographic information system (GIS) website, the Medan city sharia business used field research methods and literature studies aimed at gathering all information about sharia business data. This geographic information system aims to be able to provide information about the location of sharia businesses that are equipped with geolocatian that provide the route that will be passed directly to the location of the sharia business to be addressed. This information system can be utilized to help the community in knowing information about the locations of all sharia businesses in the city of Medan. This information system can also be used by sharia business actors to register their sharia businesses as well as a promotional event to introduce products and goods to the public at large through the Medan sharia business geographic information system. The results obtained from this website are that it can display all sharia businesses in the city of Medan, equipped with geolaction to display the route to the intended business and businesses can register their businesses so that the public can find out and hopefully this website can gradually overcome the problem to help people find sharia businesses in the city of Medan

Abstract

Kegiatan perawatan mempunyai peranan yang sangat penting , karena selain sebagai pendukung beroperasinya sistem agar lancar sesuai yang dikehendaki , kegiatan perawatan juga dapat meminimalkan biaya atau kerugian ‚?? kerugian yang ditimbulkan karena adanya kerusakan mesin. Depot LPG Gasdom I menghadapi masalah dalam hal perawatan preventif, yaitu dalam menetapkan waktu perawatan mesin. Tujuan dari penelitian ini adalah memberikan alternatif dalam menentukan waktu pelaksanaan kegiatan perawatan preventif , bagi mesin pompa yang dapat meminimalkan biaya perawatan yang dikeluarkan perusahaan. Metode yang dilakukan melalui wawancara langsung dengan pihak ‚??pihak yang berkaitan dengan masalah yang akan diteliti , hal ini adalah pihak perusahaan dari bagian maintenance. Dari hasil perawatan preventif maka peluang mesin akan rusak untuk mesin beroperasi selama 8 jam sebesar 14,8 % untuk jenis kerusakan A , 8,5 % untuk jenis kerusakan B dan 6,2 % untuk jenis kerusakan C . Maka mesin pompa selama beroperasi 8 jam peluang rusaknya cukup besar , sehingga perlu mendapat perawatan harian. Sehingga cara menentukan perawatan yang tepat bagi mesin pompa pengisap ini adalah dengan cara mesin harus mendapat perawatan sebelum waktu operasi diatas. Atau lebih tepatnya mesin harus dirawat setelah waktu operasi selama 35,27 jam untuk jenis kerusakan A , 51,2 untuk jenis kerusakan B dan 61,05 untuk jenis kerusakan C . dimana waktu diatas merupakan MTBM nya atau waktu rata-rata perawatannya Keyword: waktu perawatan, perawatan preventif, mesin pompa, MTBM
