The efficiency of a company will be determined by effectiveness of management on production resources. So, implementing a managemwntinformation system with ability to process the transaction, analysis, and planning will increase the benefit to a layer poultry farm for more easy management. By identifying the production factors and through a need assessment of a layer poultry farm company, it could be determined the elements of information needed for storage, for processing (information transformation), and for generating report. To achieve the goal, the process for system design was carried out on structured and iterative principle until an ideal design derived. Development of the software with a modular technique on a text-based operating system allows the end user to operate it on a through development of data flow diagram and prototyping lead to produce a user-friendly application. The relationship between elements of information them created base on closeness and frequently access of information to get an efficient data base with quick respond on information call, effective information processing, and a minimum data storage. Therefore, the system will be interactive, fast, and easy to use. Through a series of review and test, the system developed show the ability to store and retrieve the data including the capability to display the data history for use on ferecasting. The transaction menu that easy to understand offers all aspect of transaction as well as purchasing and marketing of the product. The transaction process will automatically update the stock data of the product, and can be use to generate a report needed. Therefore, it can be concluded that the implementation of the system will assist the entrepreneur of a layer poultry farm with a minimum of cost for investment.

This study examines the model development of the drying process of corn grains as a dynamic system. The appropriate use of a dynamic model for the drying process of corn grains could lead to an effective method for optimizing the system. The optimal control strategy can be determined by predicting the future behaviors of the process using a dynamic model. In this work, the dynamic characteristic of the water loss of corn grains during dynamics treatment of temperature in the drying process was measured in a continuous manner using a precise load cell. The nonlinear autoregressive with external input (NARX) neural network is used to identify and develop a model of dynamic characteristics of the drying process of corn grains. Then for model training and validation, the dynamic responses of the rate of water loss of corn grains to drying temperature were used. A three-layered NARX neural network model consists of 1-10-1 number neurons of each layer with two times delay was successfully developed to identify and make a model such a complex system. The developed model showed the accuracy of the rate water loss of corn grains during the drying process with the mean square error (MSE), and coefficient of determination (R-squared) values are 1.88892 x 10-4 and 0.891594 consecutively.

White rice has become the main source of carbohydrates, but in the last few years, red and black rice are getting more popular. Red and black rice can be an alternative food for people who wish to reduce the risk of diabetics due to its low glycemic index. Pigmented rice demand in Yogyakarta is continuously increasing. However, farmers are reluctant to plant pigmented rice because of their lower yields. Value chain analysis on pigmented rice is performed to provide the condition of the business’ performance for farmers who are not willing to work on pigmented rice yet. The objective of this study was to identify the main activities and to measure the performance of the value chain. The value chain performance was measured by calculating profit, marketing margin, and farmer’s share. In the business of pigmented rice nowadays, there are 5 actors involved, i.e. farmer, farmers group, association of farmers groups, distributor, and retailer. These five actors formed 5 value chains for red rice and 4 value chains for black rice. The main activities were cultivating, cropping, milling, sorting out, packing, and selling. The performance of the pigmented rice was as follows: on the red rice value chain, farmers earned the highest profit in each chain, except on the chain where the association of farmers groups was involved. The largest marketing margin was found on the farmer – association of farmer groups – retailer – end-user consumer chain. On the black rice value chain, farmers earned the highest profit in each chain, except on the chain where the farmers group was involved. The largest marketing margin found on the farmer – farmers group – distributor – retailer – end-user consumer chain. For both the red and the black rice value chain, the farmer’s highest share was obtained on the farmers – distributor – end-user consumer chain.

Trend Analysis of Red Chili Price-Formation Models Siti Mir'atul Khasanah; Mochammad Maksum; Endy Suwondo

Red chili’s characteristic flavor has been a popular element in Indonesian cuisine. A large and continuous demand for red chili is inconsistent with production volumes, causing frequent and extreme price fluctuations throughout the year. This study explores the changing trends in red chili prices to identify the influencing factors. The study was conducted in the Sleman district of Yogyakarta, Indonesia. Time-series datasets of monthly production rates and prices of chili for 3 years were subject to multiple linear regression analysis. The study found a rising trend in prices in the Sleman Regency from January 2014 to December 2016. The factors significantly influencing the red chili prices was the price of cayenne pepper. The production cost of chili, the price of tomatoes, and the price of chili for the previous 2 months had only partial and nonsignificant effects. The timing of great Muslim celebrations, such as Eid Al-Fitr and Eid Al-Adha had no significant effect on the price of red chili. However, Christmas and New Year events were associated with higher prices.

Perancangan Sistem Pendukung Keputusan Pemilihan Lokasi Agroindustri: Studi Industri Tahu di Daerah Istimewa Yogyakarta Suhendra Suhendra; Endy Suwondo; Dyah Ismoyowati; Masayuki Matsuoka

Pengembangan Sistem Pendukung Keputusan (SPK) pada studi kelayakan pemilihan lokasi agroindustri dengan analisis finansial dan lingkungan belum banyak dilakukan, khususnya untuk kelayakan industri sekala kecil menengah di area permukiman. Penelitian ini bertujuan membuat rancang bangun sistem pendukung keputusan (SPK) pemilihan lokasi agroindustri dengan kombinasi analisis finansial dan spasial lingkungan. Studi dilakukan untuk penetapan lokasi industri tahu di Daerah Istimewa Yogyakarta (DIY). Penelitian dilakukan melalui tahapan perancangan context diagram, hierarchical input process output (HIPO), dan data flow diagram. Sistem dirancang dengan 2 desain antarmuka: untuk user (interface front end) dan antarmuka oleh admin (interface back end). Hasil penelitian adalah prototype aplikasi pendukung keputusan berbasis website bernama IFSS (Industrial Feasibility Support System) dengan alamat domain http://ifssugmku.com/. Pemilihan lokasi industri dengan kriteria finansial dan lingkungan dilakukan untuk menentukan lokasi yang paling sesuai bagi pendirian industri. Uji coba sistem menunjukkan Kabupaten Gunungkidul merupakan lokasi dengan hasil kelayakan finansial tertinggi dengan nilai NPV (Rp) 879.520.243, sementara Kabupaten Bantul dan Kulon Progo merupakan daerah dengan sebaran lokasi terpilih tertinggi dari analisis lingkungan menggunakan teknik overlay. Verifikasi dilakukan dengan membandingkan hasil perhitungan manual dengan hasil perhitungan aplikasi, serta membandingkan sebaran lokasi keberadaan 14 sampel industri tahu di DIY dengan hasil pemilihan lokasi secara spasial pada ArcGIS Pro. IFSS adalah aplikasi untuk membantu memberikan petimbangan pemilihan lokasi industri secara finansial dan lingkungan.
