Abstract

Sistem keamanan adalah kebutuhan dasar manusia prioritas kedua berdasarkan kebutuhan fisiologis yang harus terpenuhi selama hidupnya, sebab dengan terpenuhinya rasa aman setiap individu dapat berkarya dengan optimal dalam hidupnya. Keamanan merupakan topik yang luas namun dalam hal ini kajian tentang keamanan dibatasi dalam lingkup keamanan rumah saja. Hasil penelitian ini adalah berupa produk sistem keamanan rumah yaitu pengunci rumah berbasis finger print. Untuk sistem pengontrol menggunakan mikrokontoller arduino Atmega328 dan didukung oleh beberapa alat yang lain agar sistem keamanan bekerja dengan baik. Hadirnya produk pengunci pintu ini merupakan inovasi baru yang dapat meningkatkan keamanan dalam lingkup rumah dan dengan menggunakan perhitungan Quality Function Deployment (QFD) untuk mengetahui tingkat kepentingan dan kepuasan dari konsumen. Pengembangan produk ini sendiri difokuskan kepada beberapa fitur tambhan yang tidak dimiliki oleh produk serupa yang ada di pasaran.

Abstract

Natural surfactant is developed as fatty acid derivate from natural resources such as palm oil, sunflower oil, and safflower oil. In South East Asia countries, the palm oil is used as the main resources of fatty acid derivate. Seed oil of Morinda citrifolia L. contains unsaturated fatty acid. It is extracted and concentrated. The concentrated fatty acid of Morinda citrifolia L. (CFAMC) is used as deinking surfactant. The CFAMC is analyzed by GCMS for its constituent and its deinking flotation performance is evaluated for yield, brightness, and ERIC of deinked pulp. Based on the old newspaper (ONP) pulp with brightness of 35.84 °ISO, and ERIC of 1982.4 ppm, the deinking flotation performance of CFAMC is approaching the natural surfactant. The brightness increase is 11.36% and 16.35%, and the ERIC reduction is 37.40% and 47.73% for CFAMC and natural surfactant respectively. SEM analysis is provided to see the residual Nanoink particles on the fibers.

Abstract

This research was conducted to find out the results that customers are interested in before and after the implementation of conventional marketing and digital marketing methods for fly ash and bottom ash products at PT PJB UP Paiton. The method used in this study is quantitative with a validity test and simple linear regression analysis which is supported by the results of the SPSS experiment. The results of this study indicate that the factors that influence digital marketing customer interest at PT PJB UP Paiton are promotion factors through social media and the application of the 7P Marketing concept namely price, promotion, place, people, and physical evidence which have a positive and significant effect. Now by implementing promotions through social media, PT PJB UP Paiton spends not so much money and gets quite a lot of customer interest and a wide reach.

Abstract

Tren meminum kopi menjadi gaya hidup khususnya kaum milenial. Mutu bubuk kopi salah satunya ditentukan oleh proses pengolahan. Proses mengolah yang tepat akan menghasiolkan bubuk kopi berkualitas. Ini yang disadari dan menjadi perhatian utama oleh mitra yakni UD Mutiara Desa. Dengan menggunakan mesin elektrik grinder, UD Mutiara Desa menghasilkan kopi bermutu, berkualitas dan memiliki daya saing. Sebelum mengenal mesin grinder elektrik, pengolahan kopi dilakukan secara manual. Mitra pun menyewa mesin tersebut karena belum memilikinya. Mesin grinder elektrik membuat proses pengolahan lebih cepat. Karena itu proses pengolahan berjalan lebih efektif dan efisien dari sisi tenaga maupun biaya. Tidak hanya itu, mitra lewat skema pengembangan masyarakat ini dibantu untuk meluaskan jaringan penjualan secara online dengan mengenalkan manajemen system pemasaran berbasis web (web-based marketing manajemen) dan information and technology based financial system (IT-based FS) peningkatan juga dikenalkan dari sisi kemasan agar lebih menarik bagi pelanggan dengan menyertakan sistem kode batang, kode kadaluarsa dan label halal MUI. Adanya perbaikan dari proses produksi sampai kepada perbaikan kemasan diakui mitra meningkatkan kepercayaan pelanggan akan mutu dan kualitas sekaligus menempatkan produk pada level pemasaran produk sejenis yang lebih popular. Dengan berada pada pemasaran yang sama, maka diharapkan penjualan akan meningkat disertai dengan kepercayaan pelanggan.

Abstract

This study presents the optimization of the field tuning configuration of the KK2.1.5 flight controller based on IMU sensor integration on a quadcopter platform to improve flight stability, maneuverability, and control responsiveness. The research employed an experimental method involving direct outdoor flight testing combined with incremental adjustment of Proportional–Integral (PI) control parameters, including roll, pitch, yaw, and self-level gains. The KK2.1.5 flight controller integrated with the MPU6050 IMU sensor was utilized to provide real-time attitude estimation through gyroscope and accelerometer measurements. The experimental evaluation focused on several flight performance parameters, namely hovering stability, roll maneuver accuracy, pitch maneuver accuracy, yaw response accuracy, altitude stabilization, response time, oscillation level, drift deviation, hovering accuracy, and control responsiveness. Ten repeated experimental trials were conducted to analyze the effectiveness of the tuning optimization process. The results demonstrated significant improvements in all flight performance indicators after iterative tuning adjustments. Hovering stability increased from 91.2% to 98.7%, while altitude stabilization improved from 90.5% to 98.3%. Furthermore, response time decreased from 1.84 s to 0.85 s, oscillation level decreased from 12.5% to 4.1%, and drift deviation was reduced from 18.2 cm to 5.3 cm. Meanwhile, hovering accuracy and control responsiveness increased to 98.8% and 98.0%, respectively. These findings indicate that the optimization of PI tuning parameters combined with IMU sensor integration significantly enhanced quadcopter flight stability, reduced oscillation and drift, and improved control accuracy. Therefore, the proposed tuning method is considered effective for improving the performance and operational reliability of low-cost quadcopter flight controller systems.
