Abstract

Yogurt di pasaran pada umumnya berbentuk cair dan kurang lazim ditemui dibanding produk minuman probiotik lainnya. Untuk itu perlu diversifikasi produk yogurt yang memiliki nilai tambah ekonomi dan bentuk yang bervariasi sehingga menjadikan yogurt sebagai minuman probiotik yang lebih diminati oleh konsumen. Tujuan penelitian adalah untuk menemukan formulasi yang tepat dalam pembuatan yogurt padat baik dalam bentuk rasa maupun tekstur. Yogurt padat dibuat dari susu sapi segar ditambah dengan maizena, susu skim, dekstrin (sesuai variabel) dan gula. Campuran dari bahan–bahan tersebut dipanaskan pada suhu ± 90 oC selama 10 menit, didinginkan sampai suhu 43 oC, dan ditambahkan starter yogurt (bakteri Steptococcus thermophillus dan Lactobacillus bulgariccus) sebesar 3 % dan diinkubasi selama 18 jam pada suhu kamar. Variabel berubah yang digunakan adalah jumlah maizena, susu skim, dan dekstrin dalam bentuk formulasi yaitu formulasi A sampai O. Dari hasil uji coba organoleptik terhadap 20 responden menunjukkan bahwa yogurt padat dengan rasa dan tekstur yang paling disukai responden adalah formulasi D yaitu pada penambahan susu skim 3 %, maizena 3 % dan tidak ada penambahan dekstrin. Formulasi D tersebut setelah diuji secara kimiawi dan mikrobiologi menghasilkan kadar keasaman 0,87%, kadar protein 8,932%, dan jumlah bakteri stater 2,45 x 109 cfu/gram sampel.

Abstract

Citrus X sinensis plants are one of the main products of Petungsewu Village, Malang Regency. So far, partners (citrus farmers) have relied on rainwater by using rainfed systems to irrigate their crops. Problems arise during dry season because limited water making watering or spraying become difficult. As a result plants are only able to produce fruits once a year while the same plants in other lands with good irrigation can produce fruits twice. To overcome the problem of limited water, it is determined to have a 4x6x2 m3 water reservoir as an water storage area for rainfed systems. While to control water usage when watering uses a cliff system using the Internet of Things (IoT) technology. In addition, to provide water storage, this activity also built a shelter on the reservoir and toilets. Because of the unavailability of electrical energy sources, this activity also provides renewable energy sources that contain solar panel energy. The watering system is carried out automatically using a soil moisture sensor if the humidity is less than 70%, so that the valve will open and the water flows. On the other hand, if the humidity is greater or equal to 70%, the valve will be closed. With the existence of this activity, partners can do automatic watering of plants during dry season, and citrus plants can produce fruits twice in a year

Abstract

Penelitian ini tidak hanya bertujuan untuk memperbaiki Algoritma Apriori (AA) dalam metode Association Rules Mining (ARM)  tetapi  juga mengusulkan suatu solusi alternatif untuk model rekomendasi bundling produk bagi ritel. Problem pemetaan biner dengan pemangkasan aturan yang sering menghilangkan produk yang potensial coba diatasi dengan tambahan parameter UWS. Perbaikan ini sekaligus berdampak pada kualitas bundling produk yang direkomendasikan. Optimasi dilakukan pada aturan yang dihasilkan oleh AA dengan parameter U_gain dan W_gain yang merupakan representasi dari berbagai atribut produk[1]. Quantity dan profit adalah bagian dari atribut item produk yang akan digunakan dalam penelitian ini. Hasil pengujian dengan menggunakan data Point of Sales (POS) menunjukan adanya perbaikan aturan. Jika menggunakan AA konvensional, aturan yang dihasilkan sering tidak mengandung item yang potensial. Hal ini karena proses seleksi ulang dengan level confidence yang lebih kritis sering menghilang aturan dengan item yang potensial. Pada sisi yang lain, sejumlah aturan yang dihasilkan sering tidak mengandung item produk yang berkualitas. Optimasi dilakukan dengan mengubah parameter minimum transaksi, minimum support dan minimum confidence yang dikombinasikan dengan perhitungan U_gain dan W_gain untuk mendapatkan aturan yang menghasilkan nilai maksimal.

Abstract

The savings and loans cooperative are a cooperative that has an important purpose in its reach and services, such as the Permata Ngijo Savings and Loans Cooperative. Activities within the cooperative itself include managing member data as well as savings and loan transactions. In systems that are still manual, such as Microsoft Excel, there is a risk of inaccurate data and takes a long time. This manual system is still less effective because the number of members and transactions continues to grow. Therefore, an application is needed as a more effective data processing and information system for members that is easier to access. This study aims to build an android-based savings and loan application using the hypertext preprocessor (PHP) programming language and my structured query language (MySQL) as data storage. Based on the android application that has been made, it shows that the black box functionality of the application runs as planned, the success rate for users reaches 90%.
