The level of coconut maturity can be determined by not only observing its shell color but also by applying audio recognition approach from knocking on coconut shell. This knocking sound distinguishes young, fairly mature, and mature coconut. Recognizing the sound characteristic of knocking on coconut is usually performed by the skilled ones who are having extensive experiences and sound sensitiveness of coconut knocking. In order to substitute the skilled ones, the design of coconut maturity prediction device with acoustic frequency detection is invented. The coconut sound signal is tapped by stethoscope which is connected to MAX9814 noise sensor. Arduino Due micro-controller is used to process the signal. The process in processing the signal consists of: conversing analog signal to digital, screening the signal, and finding the average value of sound signal frequency spectrum. The signal screening uses bandpass digital filter, type IIR (Infinite Impulse Response) Elliptic order 7. This filter is utilized in order that the signal that is being processed is not some noise but the signal of knocking sound on coconut. The calculation of average value of sound signal frequency spectrum uses FFT (Fast Fourier Transform) analysis. The maturity prediction is carried out using the classification method of Naive Bayes. The input is three average value of knocking sound frequency and coconut size, and the output is classification of coconut maturity. From this research, it is generated 80% of system success rate.

Facial expressions are one of the ways humans communicate to convey one's emotions to their communication partner nonverbally. Therefore, human facial expressions can be used for various purposes, one of which is knowing customer satisfaction. So far, customers of Bank Rakyat Indonesia (BRI) provide feedback on service quality using only a polling system, namely by filling out a criticism and suggestion form and then entering it in a suggestion box which is distinguished between satisfied and dissatisfied. However, such a method is less effective because it can be easily manipulated by customers and customers are often indifferent to the feedback. So that the improvement of service quality tends to be less effective. This research will design a system that can recognize human facial expressions to determine the level of customer satisfaction with input data in the form of video data taken by a webcam camera with the viola-jones method to detect faces and determine facial patterns. Then the facial data will be classified using the K-Nearest Neighbor method to determine the type of facial expression. Determination of the value of k will determine the success rate of facial expression detection. The processed data will be displayed on a liquid crystal display (LCD) and then stored in a MySQL database. The results showed that the accuracy of facial expression detection was 80.77% from 52 facial expression data.

Pengelolaan kualitas air pada budidaya udang merupakan satu aspek keberhasilan budidaya udang. Sistem resirkulasi ini merupakan salah cara yang digunakan untuk mengontrol kualitas air pada tambak. Microbubble mengeluarkan gelembung dengan ukuran lebih kecil sehingga kadar oksigen terlarut lebih stabil dan tahan lama. Pertumbuhan udang dipengaruhi oleh suhu, pH (Potential of Hydrogen), dan kadar oksigen pada kualitas air tambak. Dari hasil pengujian sensor DO (Dissolved Oxygen) didapatkan hasil angka dengan rentang 3-9 mg/l yang mana setiap waktunya selalu naik turun, ketika kadar oksigen turun maka pompa air akan aktif dan microbubble bekerja untuk menghasilkan gelembung oksigen agar oksigen yang turun akan kembali normal sesuai set point yaitu 4-5 mg/l. Untuk sensor pH hasil pengujiannya cukup stabil di angka 7-8,5 hasil tersebut masih normal untuk tambak udang, dan yang terakhir hasil pengujian sensor DS18B20 didapatkan hasil pembacaan suhu dari 27-30°C. Seluruh hasil pengujian disimpan melalui RTC (Real Time Clock) secara real time selama 24 jam dan hasil dapat diunduh pada website Thingspeak dalam bentuk dokumen excel. Hasil dari pengujian juga disimulasikan menggunakan matlab dan dihitung manual dengan metode fuzzy tsukamoto. Perhitungan manual metode fuzzy tsukamoto pada sistem pengaturan tambak udang dengan 3 input dan 1 output memperoleh nilai defuzzifikasi 65,464 nilai tersebut dijadikan indikator berapa besar kecepatan pompa air sehingga microbubble bisa menstabilkan kadar oksigen terlarut.
