Edamame grade is determined based on edamame quality parameters with several parameters that are quite a lot. The process of deciding edamame grade is relatively complicated and challenging. To determine the edamame grade, an experienced expert in the field is needed. With limited grading experts, the design of expert systems for grading edamame can help users or companies to determine edamame grade.  This study aims to design an expert system for determining edamame grade, which can determine the quality of edamame accurately. The Design of an expert system in this research uses the forward chaining method.  The stages of designing an expert system include problem identification, knowledge acquisition, building a data flow diagram, compile the database, building a decision tree diagram, and developing a user interface. The results showed that the expert system has been verified and validated well. Verification test results show that all the menu buttons on the expert system application are functioning correctly. Then, the validation results also show that the edamame quality output produced by the expert system is compatible with the expert solution, meaning that the expert system's output data is by following with the results of the decision given by the expert. In testing the validation of determining the quality is appropriate.  The results of the verification and validation of the edamame grading expert system show that the expert system has produced satisfactory outcomes. Expert system output is compatible with the solution provided by the expert.

Rice (Oryza sativa) is one of the main commodities in Indonesia. One of the inhibitors of rice crop production is disease. Rice plant diseases can be caused by pathogens, host plants or bad environment. The process of diagnosing rice diseases requires expertise, knowledge and experience. This study aims to build an expert system that can diagnose 13 types of rice plant diseases from 43 symptoms based on the knowledge of 3 experts with forward chaining reasoning methods and mobile-based dempster shafer calculation methods. The testing technique used is black box testing, theoretical calculation testing, system accuracy testing and MOS (Mean Opinion Score) testing. The black box test results state that the expert system has 100% compatibility in terms of functionality. The theoretical calculation test results state that the expert system calculations are in accordance with the results of manual calculations. System accuracy testing results from 30 test cases get an accuracy of 81.11%. The results of MOS testing conducted on 30 respondents produced MOS of 4.2 from a scale of 5 categorized into a good system.

Ikan tuna merupakan komoditi perikanan andalan yang mudah sekali mengalami perubahan mutu. Pengawetan diperlukan untuk memperpanjang umur simpan ikan terutama di saat-saat musim ikan dan agar ikan dapat sampai ke tangan konsumen sebelum mengalami pembusukan. Teknologi pengawetan yang dapat diterapkan adalah pemberian asap cair karena bahan mengandung fenol yang berperan sebagai antioksidan. Tujuan dari penelitian ini adalah mengetahui pengaruh pemberian asap cair terhadap kandungan protein yang terdapat pada fillet ikan tuna dan mengetahui umur simpan fillet ikan tuna dengan penggunaan asap cair sebagai bahan pengawet yang disimpan pada suhu kamar (27o) dengan menggunakan metode ESS (Extended Storage Studies). Konsentrasi asap cair yang digunakan dalam penelitian antara lain konsentrasi asap cair 4%, konsentrasi asap cair 6% dan tanpa pemberian asap cair. Penelitian ini menggunakan metode ESS (Extended Storage Studies) yang diperoleh dari uji sensori selama penyimpanan dengan menentukan kesukaan terhadap penampakan, warna, bau, tekstur dan parameter lain yang diamati yaitu uji pH, kadar air dan uji protein. Hasil penelitian menunjukan bahwa dengan penambahan asap cair tidak mampu mempertahankan kadar protein yang terkandung pada fillet ikan tuna selama proses penyimpanan dengan rata-rata penurunan kandungan protein untuk semua perlakuan sekitar 4,01% dan penambahan asap cair 6% mampu disimpan selama 54 jam, 2,33 kali lebih lama dibandingkan dengan tanpa penambahan asap cair. Tuna fish is a commodity of fishery products is very easly get change of the quality. Preservation is needed to prolong the life of save the fish especially at the time when the fish season and so that the fish can reach the consumer before experiencing the decay. Preservation technology that can be applied is the giving of liquid smoke because the ingredients contain fenol who act as antioxidants. Objective of this research is to find out the shelf life of tuna fish fillets by using the liquid smoke as preservatives and stored at room temperature (27o). This research uses the method ESS (Extended Storage Studies) obtained from sensory test during storage with determine the gladness of the appearance, color , smell, texture and other parameters observed namely pH test, the level of water and protein test. Based on the research results obtained using the method ESS, shows that the quality of tuna fish fillets with the addition of liquid smoke is best obtained on the treatment of liquid smoke concentration of 6% with long storage time during 54 hours, with the main quality parameters cause damage obtained from pH test results and sensory test.

Food is a basic requirement for human beings. As the population increases, food demand will continue to increase. Food problems in Indonesia are inseparable from rice and flour, in addition to other foodstuffs such as cassava, corn, and sago (Colas, 1994). Efforts to increase rice production are not easy, since there is a massive diversion of agricultural land functions into residential and industrial areas. Indonesia has the potential of tubers as a source of carbohydrates as well as raw materials of local flour. One of the sources of local starch that can be used as flour is canna (Canna edulis Ker). The obstacles faced by smallholders/ small and medium industries (SMEs) who use canna flour that is in the post-harvest process to produce canna flour. Making starch/ canna flour generally still done traditionally, thus affecting the productivity and quality of flour produced. This study aims to design a multi-function canna processing machine to produce canna flour as food. The research method used is the engineering method, which is the activity of designing the build canna processing machine. Canna machine has been successfully made with two main functions namely: the solvent and slicer. The main components of the machine consist of: frame, solvent unit, slicer unit, transmission system, output outlet, wheel, and drive motor. Dimensions of the machine that is 90 cm long, 85 cm wide and 100 cm high. While the frame dimension is 80 cm long, 70 cm wide and 65 cm high. Functional test results show that all components work properly.   Keywords: canna, canna machine, multifunctional, engine design   ABSTRAK   Pangan merupakan kebutuhan pokok bagi manusia. Seiring dengan meningkatnya jumlah penduduk, maka kebutuhan pangan akan terus meningkat. Masalah pangan di Indonesia tidak terlepas dari beras dan terigu, disamping bahan pangan lainnya seperti ubi kayu, jagung, dan sagu (Colas, 1994). Upaya untuk meningkatkan produksi beras bukan hal mudah, karena banyak terjadi pengalihan fungsi lahan pertanian secara massal menjadi area pemukiman dan industri. Indonesia  memiliki  potensi  umbi-umbian sebagai sumber karbohidrat sekaligus bahan baku tepung lokal. Salah satu tanaman sumber pati lokal yang dapat dijadikan tepung adalah ganyong (Canna edulis Ker). Kendala yang dihadapi oleh petani atau Industri Kecil Menengah (IKM) yang memanfaatkan tepung ganyong adalah pada proses pasca panen untuk menghasilkan tepung ganyong. Pembuatan pati atau tepung ganyong umumnya masih dikerjakan secara tradisional, sehingga mempengaruhi produktivitas serta kualitas tepung yang dihasilkan. Penelitian ini bertujuan untuk merancang bangun mesin pengolah ganyong multi fungsi sehingga dihasilkan tepung ganyong sebagai bahan pangan. Metode penelitian yang digunakan adalah metode rekayasa, yaitu kegiatan merancang bangun mesin pengolah ganyong. Mesin ganyong telah berhasil dibuat dengan dua fungsi utama, yaitu: pemarut dan pengiris. Komponen utama mesin terdiri dari: rangka, unit pemarut, unit pengiris, sistem transmisi, saluran pengeluaran hasil, roda, dan motor penggerak. Dimensi mesin yaitu panjang 90 cm, lebar 85 cm dan tinggi 100 cm. Sedangkan dimensi rangka, yaitu panjang 80 cm, lebar 70 cm dan tinggi 65 cm. Hasil uji fungsional menunjukkan bahwa semua komponen berfungsi dengan baik.   Kata kunci: ganyong, mesin ganyong, multi fungsi, rancang bangun mesin
