Abstract

Application of artificial inteligent by using fuzzy logic can be one of way to handle supply chain situation in uncertainty environment. It was widely concern to study a supply chain using fuzzy logic that most needed. Ain of the study was apply fuzzy logic in determination of supply allocation for superior product in vegetables supply chain. Models was developed in three sub models. First was determination vegetables types that superior by using pareto technique and exponential compaarison method (MPE). Second was expert system to determine supply needed and finally was optimizing supply allocation using fuzzy multi-objective linear programming. The model was applied in a vegetables agroindustry that superior product selected was red paprica. Analysis againts model behaviour is conducted for pesimistic and optimistic scenarios. Abstract in Bahasa Indonesia : Penerapan kecerdasan buatan dengan logika fuzzy bisa menjadi salah satu cara untuk mengatasi situasi rantai pasok dalam lingkungan ketidakpastian. Perhatian yang lebih luas untuk pembahasan rantai pasok menggunakan teknik fuzzy masih sangat dibutuhkan. Studi ini bertujuan menerapkan logika fuzzy dalam penentuan alokasi pasokan untuk produk unggulan pada rantai pasok agroindustri sayuran. Model yang terdiri dari tiga sub model. Sub model pertama adalah penentuan jenis sayuran yang diunggulkan menggunakan kombinasi teknik pareto dan metode perbandingan eksponensial (MPE). Sub model kedua adalah sistem pakar untuk menentukan kebutuhan pasokan menggunakan logika fuzzy. Sub model ketiga adalah optimasi alokasi pasokan menggunakan programa linear obyektif majemuk fuzzy. Model yang dibangun kemudian diterapkan pada sebuah perusahaan agroindustri sayuran dengan produk unggulan terpilih adalah paprika merah. Analisis terhadap prilaku model juga dilakukan untuk skenario pesimis dan optimis. Kata kunci: fuzzy, sistem pakar, MPE, obyektif majemuk, sayuran

Abstract

Knowledge about suitability of the land and the plants can minimalize harvest plant problem. The spread of information technology and digital era also change the ways to explain and distribute information and knowledge used for recognize land suitability, with the creation of expert system. Process to recognize land suitability in this system using 19 parameter included physical and chemistry characteristics, and also nature factors such as temperature and rain fall. For all of these parameters, there are 2 complementary parameters to replace data about tekstur, drainase, and slope. Object in this research are 14 kinds of food plants. This system using Fuzzy Inference Systems (FIS) method for processing data. User can choose trapesium or Gauss function for fuzzificy the data. Based on actual values of the land, this system will determine the suitability of the land for food plants and for specific kinds of food plants. This system also determines about limitation factors for the land and gives some managerial suggestion for handling those factors. The results of this system also included about plants grow requirement and suitability location on 2 districts at East Java Province. Abstract in Bahasa Indonesia: Pengetahuan para pelaksana pertanian dalam menentukan kesesuaian lahan dengan jenis tanaman yang akan ditanam tentunya akan dapat meminimalisasikan berbagai permasalahan panen yang dapat terjadi. Perubahan yang terjadi dalam bidang teknologi informasi dan era digital, juga telah mendukung dan merubah cara penyebaran informasi dan pengetahuan, antara lain melalui penggunaan sistem pakar. Sistem pakar ini menggunakan 19 parameter, termasuk parameter fisik dan kimia, serta faktor alam seperti suhu dan curah hujan, dalam menentukan kesesuaian lahan. Di antara seluruh parameter yang digunakan, terdapat 2 parameter pengganti yang dapat digunakan untuk menggantikan parameter tekstur, drainase, dan lereng. Objek yang digunakan dalam penelitian ini meliputi 14 jenis tanaman pangan. Metode yang digunakan adalah Fuzzy Inference Systems (FIS), dimana pengguna dapat memilih jenis fungsi trapesium atau gauss yang akan digunakan untuk memproses data. Berdasarkan data aktual, sistem ini akan menentukan tingkat kesesuaian lahan yang akan digunakan oleh suatu jenis tanaman, berikut dengan faktor penghambat yang ada serta saran manajerial yang dapat diterapkan untuk mengatasi keberadaan faktor penghambat, dan lokasi yang sesuai untuk suatu jenis tanaman tertentu. Penentuan lokasi terbatas pada 2 propinsi di Jawa Timur. Kata kunci: kesesuaian lahan, fuzzy inference systems, system pakar.
