Water is very important for all aspects of life on earth, agriculture is one of the fields that really need large amounts of water because of the use of water in the
process of plant photosynthesis. Water that has good quality is if the water is not excessively polluted by harmful chemicals or minerals. One indicator that water is polluted is a change in temperature and pH (acidity) of the water. Temperatures that are too hot in the water will interfere with the growth of plants and other microorganisms. While the normal pH of water has a pH that ranges from 6.5 to 7.5. The quality of water and soil is very important in agriculture. The level of acidity (pH) and soil temperature are one of the things that affect plant fertility. Therefore, the quality of water and soil on agricultural land is one of the important things that needs special attention in its management. One solution so that water and soil quality can be monitored and managed efficiently is to utilize a Wireless Sensor Network based on the Internet of Things (IoT). The use of the ESP8266 Module as a WIFI module, is widely used by Internet of Things-based applications because the price is cheap so it reduces a lot of costs and has a fairly good speed of 80 MHz. This study aims to develop the concept of a Wireless Sensor Network by utilizing the ESP8266 module to monitor pH values using a pH Meter Analog Kit sensor and temperature from agricultural land using a DS18B20 Waterproof sensor and can be monitored at any time using a smartphone.

Mengisi saos ke dalam botol secara manual adalah pekerjaan yang cukup merepotkan. Proses produksi yang seharusnya bisa lebih efektif dan efisien menjadi sedikit terhambat. Keadaan ini menimbulkan kekhawatiran bagi perusahaan yang memerlukan proses produksi secara singkat dan akurat demi memenuhi kebutuhan konsumen agar tepat waktu.
Hal ini membuat perusahaan yang bergerak di bidang F&B bernama JJCOW sedikit mengalami kewalahan. Perusahaan ini bergerak di bidang barbeque home service. Salah satu produk JJCOW yang populer adalah saos signature JJCOW. Kebutuhan konsumen akan produk ini cukup tinggi. Saat ini, JJCOW masih memproduksi saos signature ke dalam botol menggunakan cara manual sehingga membuat proses produksi sedikit terhambat dan memakan waktu yang cukup lama.
Berdasarkan latar belakang di atas, penulis ingin memudahkan proses produksi di JJCOW dengan membuat alat pengisi saos otomatis berbasis Arduino UNO agar lebih efektif dan efisien. Untuk membuat alat ini, komponen yang diperlukan yaitu mikrokontroller Arduino UNO, kabel jumper, breadboard, sensor infrared, relay 1 channel, lcd 16x2, i2c 1206, push button, pompa diafragma 12v 2a, dan adaptor 12v 3a.
Setelah melakukan uji coba, waktu yang diperlukan untuk pengisian satu botol saos sangat sedikit. Untuk pengisian satu botol saos, waktu yang diperlukan tidak sampai 2 detik.

Portal berita online merupakan situs yang memuat segala berita dan artikel untuk dibaca pengunjung, berisi opini dan komentar-komentar seputar politik, teknologi dan lain-lain. Ada berbagai portal berita online yang bisa kita akses, antara lain antaranews.com dan tribunnews.com. Meningkatnya jumlah portal berita online, mengakibatkan tingginya jumlah berita yang bisa dibaca masyarakat. Oleh sebab itu, kebutuhan peringkasan teks (text summarization) semakin diperlukan masyarakat untuk kemudahan dan penghematan waktu. Sistem peringkasan teks otomatis yang digunakan pada penelitian sebelumnya, menggunakan metode Maximum Marginal Relevance (MMR) berbasis Vector Space Model (VSM) dengan representasi algoritma pembobotan kata menggunakan TF-IDF-DF (Term Frequency-Inverse Document Frequency-Document Frequency). Pada algoritma ini, kata yang sering muncul memiliki jumlah yang tinggi, sehingga bobot hubungan antara sebuah kata dan kalimat rendah, sehingga metode ini cocok untuk artikel panjang yang memiliki banyak jumlah kalimat. Oleh karena itu, perlu diusulkan metode lain untuk menghitung kesamaan kata dengan menggunakan boolean model dengan representasi jaccard, dice dan cosine coefficient. Ketiga metode ini digunakan untuk mengetahui document yang paling relevan untuk kumpulan kata kunci (query) yang diberikan. Setelah proses boolean, perlu dilakukan metode ekstraksi teks yang diterapkan yaitu MMR (Maximum Marginal Relevance) untuk meringkas document tunggal dengan cara melakukan rangking, membandingkan similarity query dan document, dan similarity antar document. Dari hasil penelitian, boolean model memiliki nilai akurasi yang lebih tinggi daripada VSM, dan  di antara ketiga metode boolean model, metode cosine coefficient lebih unggul dengan akurasi 59.3 %.
