Abstract

Kelapa merupakan salah satu penghasil minyak nabati yang digunakan dalam kehidupan sehari-hari. Daging buah kelapa dapat dijadikan berbagai macam olahan produk, salah satunya dijadikan Virgin Coconut Oil (VCO). Proses pembuatan VCO terbaik selama ini menggunakan metode sentrifugasi. Perlakuan pretreatment ultrasound diharapkan mampu membantu proses pemecahan emulsi sebelum dilakukan sentrifugasi pada santan kelapa untuk menghasilkan rendemen dan kualitas VCO yang lebih optimal. Secara teoritis pemecahan emulsi dicapai dari tiga mekanisme utama yaitu flokulasi, koagulasi, dan peleburan sehingga pretreatment ultrasound diasumsikan meningkatkan momentum dan kekuatan melalui getaran mekanik. Faktor yang dikaji dalam penelitian ini adalah alat sonikator dan lama waktu perlakuan yang menghasilkan rendemen dan kualitas VCO tertinggi. Tujuan penelitian ini untuk mendapatkan besaran frekuensi dan lama waktu pretreatment ultrasound yang menghasilkan rendemen dan kualitas VCO terbaik. Pemilihan perlakuan terbaik menggunakan metode Zeleny dengan multiple atribute. Parameter yang dipilih sebagai atribut antara lain rendemen, kadar air, berat jenis, dan FFA. Hasil perlakuan UAE kondisi terbaik menurut perhitungan Zeleny terdapat pada frekuensi 20 kHz dengan waktu 15 menit menghasilkan rendemen 14.88%, berat jenis 0.85, kadar air 0.05% dan FFA 0.17%. Perlakuan terbaik UAE memenuhi standar APPC dan SNI untuk kadar air dan asam lemak bebas, sementara berat jenisnya belum memenuhi standar APPC.

Produk mi merupakan salah satu jenis olahan pangan yang sangat digemari oleh masyarakat Indonesia. Jenis produk mi yang mampu bersaing di pasar ialah mi kering. Tingginya peningkatan konsumsi dan kebutuhan mi ini akan seiring meningkatkan volume impor gandum sebagai bahan baku utama. Ubi jalar merupakan salah satu komoditas pangan sumber karbohidrat yang cukup penting di Indonesia. Penelitian tentang mi kering dari ubi jalar telah dilakukan. Skala laboratorium merupakan acuan dasar dari sebuah proses produksi mi kering ubi jalar. Dalam proses pembuatan industri, skala laboratorium tidak cukup untuk memenuhi tingginya kebutuhan konsumen sehingga diperlukan proses penggandaan skala untuk mengatasi masalah tersebut. Tujuan penelitian ini adalah mengetahui mutu fisik dan kimia mi kering ubi jalar skala ganda dibandingkan dengan skala laboratorium dan untuk mengetahui mutu organoleptik mi kering hasil skala ganda dibandingkan dengan mi kering yang beredar di pasaran. Penelitian dibagi dalam dua tahap yaitu perbaikan formulasi skala laboratorium dan penggandaan skala mi kering ubi jalar yang terbaik dari skala laboratorium. Hasil penelitian menunjukkan pada proses penggandaan skala mi kering ubi jalar hasil yang didapatkan berbeda dengan skala laboratorium. Kualitas organoleptik (rasa, aroma, tekstur dan warna) mi kering ubi jalar pada skala ganda lebih rendah dibandingkan mi kering hasil skala laboratorium. Kualitas fisik mi kering ubi jalar hasil penggandaan skala pada parameter hidrasi mi dan rasio pengembangan lebih rendah, namun daya patah jauh lebih tinggi dibandingkan dengan hasil skala laboratorium. Kualitas kimia mi kering ubi jalar yang dihasilkan masih dibawah standar SNI untuk kadar protein, kadar air, dan kadar abu.

The Agribusiness information outputs consist of suppliers, sale transactions, buyers, purchasing transactions, and commodities information. The required data were Government, Suppliers, and Buyers. The system users would be Suppliers, buyers, Managers of Agribusiness Terminals, Sub Agribusiness Terminal and main markets, and related government and private bodies. A descriptive-analytical method, so-called the prototyping approach, was chosen. The research was started in two main stages, first, an identification of users’ needs and a development of a system prototype that covered the conceptual design, architecture design, and program implementation (coding). The architecture of the design consisted of data base, process, user interface, and network design. The software employed were Gammu, Firebird 1.5, SMS Demon and Delphi 7.0. The hardware required include the Auto Respond SMS application, a compute set equipped with a GSM modem, and a GSM network. The information in the developed system, however, was not real time since the data was first collected from the sources, then the collected data was input and processed. Therefore, there will be a time delay, depending on the time to execute this sequence. The results indicated that the developed system was able to provide users the relevance information within 15-30 seconds at a cost of not more than regular SMS charge.   Key words: SMS-based horticultural information system
