Abstract

This study aims to design a Solar Home System with an Arduino-based Smart Switching system so that the use of electrical energy generated by solar panels can be adjusted without adding power from other electricity sources, such as PLN. Calculation of Leveled Cost of Energy (LCOE) is used as the basis for the switching process that will be carried out to regulate the use of household appliances that are routinely used, regulate electricity consumption automatically, minimize usage, and calculate the effectiveness of electric power usage. The way SHS works is to collect electrical energy from sunlight, then convert DC voltage to AC so that it can be used to run household electronic equipment. To accommodate the adequacy of electrical power, an automatic adjustment is made for household appliances that are routinely used, namely house lights, which includes setting the lights on and off and the number of lights that can be activated. The advantage of this research is that the SHS system is integrated with the automatic setting of the lights installed in the house so that the number of lights on will adjust the availability of electrical energy in the battery. In addition, with the LCOE method, the level of usage can be calculated so that users can save electricity. From the results of usage testing, it is found that the application of this switching technology provides benefits for users because it is no longer dependent on PLN supply. From an economic point of view, based on the calculation of Leveled Cost of Energy (LCOE), there is a kWh value savings of Rp. 77, - for each kWh price or about 4.53% compared to purchasing electricity with prepaid mode.

Abstract

The purpose of this research is to present the quality measurement of internet-based Islamic corporate governance and identify its effects on stakeholder trust. In measuring the implementation of corporate governance, this study uses the method of measuring the quality of Islamic corporate governance (IBCGS), as the development of IBCG and IBCG Rating Modified. This research uses descriptive exploratory analysis tools with PLS-SEM as the statistical tool. The object of this research is a company registered in the Jakarta Islamic Index (JII). The results showed that the implementation of corporate governance based on IBCGS by sample companies had been implemented but with varying quality. Meanwhile, the implementation of corporate governance in sharia companies positively influences shareholder trust manifested by their return on equity, stock returns and earnings per share. The findings of this study are expected to contribute to the signalling theory and agency theory in explaining the influence of the quality of corporate governance on the shareholder trust that should be concerned by sharia companies.

Abstract

Penetasan telur burung puyuh dapat dilakukan dengan dua cara, yaitu alami dan buatan. Alami artinya telur burung puyuh dierami langsung oleh induknya. Sedangkan cara buatan artinya telur burung puyuh ditetaskan dengan bantuan mesin tetas. Tujuan dari penelitian ini adalah merancang, mengimplementasi, dan menguji sistem pendukung keputusan performa produksi burung puyuh dengan metode profile matching. Metode profil matching adalah metode yang mengasumsikan bahwa subyek yang diteliti harus memenuhi tingkat variabel prediksi ideal bukan tingkat minimal.Terdapat tiga spek yang digunakan dalam menentukan performa produksi burung puyuh. Aspek tersebut adalah genetik, ransum pakan, dan lingkungan. Hasil dari penelitian ini adalah aplikasi yang dibangun dapat membantu, mempercepat,dan mempermudah proses pengambilan keputusan performa produksi burung puyuh. Selain itu, aplikasi yang dibangun mudah digunakan.

Abstract

Membatik merupakan teknik menghias kain tradisional Indonesia dengan menggunakan lilin untuk membuat pola dan desain. Penggunaan batik antara satu individu dengan individu lainnya memang berbeda, bergantung dari ciri fisik dan karakter pemakai agar terlihat bagus, elegan, dan jragem (berwibawa). Kesesuaian pengguna batik ini merupakan hal yang penting mengingat kebutuhan masyarakat terhadap penampilan yang nyaman, pantas, dan menarik. Ingatan manusia dan ahli yang memahami batik sangatlah terbatas, maka diperlukan sebuah sistem untuk menjaga salah satu warisan budaya ini agar bisa bertahan. Tujuan dari penelitian ini adalah untuk mengembangkan dan menerapkan basis pengetahuan dan sistem pakar yang dapat dengan cepat mencocokan batik yang sesuai dengan ciri fisik pengguna khususnya batik Blitar. Sistem ini akan menarik kesimpulan dari beberapa jenis masukan yang masuk ke sistem berdasarkan warna kulit, ukuran pakaian, usia, dan jenis kelamin. Program ini menggunakan PHP sebagai bahasa pemrograman dan MySQL sebagai basis data sistem.

Abstract

Difficulty in getting a dictionary of the term livestock is an obstacle for the academic community of the Faculty of Animal Husbandry, Balitar Islamic University to find out the meaning of the term livestock. Along with the progress of the times, the need for a dictionary can certainly be met with technological sophistication, one of which is through a dictionary application. This study designed the term dictionary dictionary application by applying the Boyer Moore algorithm matching string. This translation process is carried out in the form of words where each keyword term searched will appear along with the meaning of the term farm. The term farm dictionary application is designed using Microsoft Visual Visio 2007 and the application is implemented based on the website. The boyer moore string matching algorithm does word matching by applying the FilterString function and the search function. The FilterString function detects each character in a keyword while the search function matches keywords from the FilterString function with terms in term data in the database. The results of beta testing showed that the system obtained an average value of 71.58%, meaning that users had high satisfaction with the term dictionary application.

Abstract

This forecasting application can be applied to the pharmaceutical industry including the PPNI Wlingi pharmacy, which sells a variety of over-the-counter and prescription drugs and medical devices. The purchase of over-the-counter drugs is recorded daily. This, if left unchecked, will caused an accumulate sales data without any utilization of these data. Instead, the data can be used to determine the inventory turn over of goods so that it is useful in future sales strategies. One method that can be used is the Association Rule Mining (ARM) method which implement association rules. Association rule can be used to predict patterns of interrelationship between items that are often purchased by customers. The result will make it easier for companies to make the decision to increase or decrease the stock so that the inventory turn over will be shortened and reduce the risk of innefficient accumulation of goods.
