Abstract

Traceability merupakan metode yang dapat dilakukan oleh pengelola industri pangan untuk memberikan informasi yang terkait produk yang dihasilkan secara keseluruhan. Sistem traceability masih memiliki keterbatasan penyampaian informasi mengenai produk kepada para konsumen khususnya di BOS Fresh. Sehingga, dibutuhkan traceability website yang mampu mengelola serta menyampaikan data tersebut secara digital kepada konsumen. Tujuan dari penelitian adalah merancang traceability website yang baik, responsif, dan mudah diakses. Perancangan traceability website ini meliputi beberapa tahap diantaranya pengembangan website, perancangan use case diagram, perancangan class diagram database, perancangan user interface website, melakukan hosting, hingga tahap pengujian dengan metode white-box, black-box, dan user acceptance testing. Pengguna pada traceability website dibagi menjadi dua, yakni user admin dan konsumen dengan halaman yang berbeda. Pada halaman user admin memiliki beberapa menu seperti login, input data, update data, menghapus data, serta mencetak QR Code. Konsumen hanya dapat mengakses halaman untuk melihat data saja dengan cara memindai QR Code yang telah disediakan. Hasil pengujian metode white-box dengan menguji jalur logika pada bahasa pemrograman mendapatkan interpretasi “Valid” untuk semua variabel pengujian. Hasil pengujian metode black-box dengan menguji seluruh fitur yang dimiliki website mendapatkan interpretasi “Berhasil” untuk semua variabel pengujian. Serta hasil pengujian metode user acceptance testing dengan menguji pengoprasian website mendapat nilai rata-rata 3,48 dengan interpretasi “Sangat Puas”, dengan menguji kelengkapan data mendapat nilai rata-rata 3,57 dengan interpretasi “Sangat Puas”, serta dengan menguji tampilan website mendapatkan nilai rata-rata 3,64 dengan interpretasi “Sangat Puas”. Berdasarkan seluruh hasil pengujian, dapat disimpulkan bahwa traceability website telah berjalan dengan baik, responsif, dan mudah untuk diakses. ABSTRACT Traceability is a method that can be used by food industry managers to provide information related to the products produced as a whole. The traceability system still has limitations in conveying product information to consumers, especially at BOS Fresh. So, a traceability website is needed that is able to manage and convey this data digitally to consumers. The aim of the research is to design a good, responsive, and easily accessible traceability website. The design of this traceability website includes several stages including website development, use case diagram design, database class diagram design, website user interface design, hosting, and the testing phase using the white-box, black-box, and user acceptance testing methods. Users on the traceability website are divided into two, it is a admin users and consumers with different pages. On the admin user page, there are several menus such as login, input data, update data, delete data, and print a QR Code. Consumers can only access the page to view data by scanning the QR Code provided. The results of testing the white-box method with logic path testing in programming languages get the "Valid" interpretation for all test variables. The results of testing the black-box method by testing all the features of the website get the interpretation of "Success" for all test variables. As well as the test results of the user acceptance testing method by testing the operation of the website getting an average value of 3.48 with the interpretation of "Very Satisfied", by testing the completeness of the data getting an average value of 3.57 with the interpretation of "Very Satisfied", and by testing the appearance of the website get an average value of 3.64 with the interpretation of "Very Satisfied". Based on all the test results, it can be concluded that the traceability of the website has been running well, is responsive, and easy to access.

Abstract

Respirasi tanah merupakan salah satu indikator penting dalam suatu ekosistem tanah yang menunjukan aktivitas mikroorganisme dan metabolisme dalam tanah. Respirasi tanah diukur dengan metode tabung mikrorespirasi sebagai pengukuran lapangan dan titrasi asam basa sebagai analisis laboratorium. Metode tabung mikrorespirasi ini adalah cara cepat mengukur respirasi tanah, namun data yang dihasilkan hanya dapat dilihat secara visual dan tidak diketahui nilainya. Oleh karena itu, dilakukan pengolahan citra dari metode tabung mikrorespirasi ini untuk mengestimasi nilai respirasi tanah serta mengetahui model estimasi terbaik menggunakan machine learning. Citra diakuisisi kemudian diolah dengan pengolahan citra meliputi konversi Red, Green, Blue (RGB) ke Hue Saturation Value (HSV), augmentasi citra, serta ekstraksi fitur data citra. Pengembangan model estimasi respirasi tanah menggunakan tiga algoritma yaitu Multiple Linear Regression (MLR), Back Propagation (BP), dan Random Forest (RF). Hasil dari penelitian ini adalah diperoleh akurasi model dengan nilai R² dari ketiga model yaitu MLR = 0,28, BP = 0,53, RF = 0,77 dan nilai estimasi dari ketiga model MLR = 7,62 mg/g , BP = 4,38 mg/g , RF = 4,57 mg. Dari hasil tersebut, dinyatakan bahwa model dengan algoritma RF merupakan model terbaik untuk mengestimasi nilai respirasi tanah.

Abstract

The annual rice planting cycle produced 6.73 tons of dry straw per hectare. Rice straw had beneficialnutrients for plants, but farmers often burned or buried it to reduce waste and enhance soil fertility. Becausestraw was hard to decompose, additional decomposers like bacteria were needed. This study aimed toinvestigate the short-term impact of rice straw management on soil organic carbon (C-organic) and the C/Nratio. The experimental design used was Nested Design. The study involved three straw managementtreatments: burning (BR), straw incorporation without EM4 addition (S0), and straw incorporation withEM4 addition (S1). Laboratory analysis was conducted on the C-organic and C/N ratio parameters.Differences in soil parameters observed before and after straw management treatments were analyzed usingthe Wilcoxon Signed Rank Test. The analysis showed an increase in C-organic after treatment: 29.7% forburning, 10.9% for straw incorporation, and 10.2% for straw incorporation with EM4. The rise in C-organicafter straw management treatments is due to the mineralization of soil organic matter. This mineralizationis indicated by average C/N values below 20, although the C/N ratio after burning increased by 56% andafter straw incorporation with EM4 increased by 0.35%. The average C/N ratios from all treatments rangedfrom 9.1 to 16.8. In the short term, all three straw treatments can increase organic carbon and C/N ratiosbelow 20.
