Abstract

Skin health is essential for everyone. In addition to supporting someone who can reduce self-confidence, skin diseases can also interfere with a person's concentration in activities. An expert system is a system designed to be able to imitate the expertise of an expert in answering questions and solving a problem. The expert system will solve a problem obtained from a dialogue with the user. With the help of an expert system, someone who is not an expert can answer questions, solve problems, and make decisions that an expert usually makes. This needs to be anticipated and handled seriously, especially for types of skin diseases, some of which can be fatal, and some can even be classified as cancer. Experts are needed to diagnose each disease in this case, but consultation with experts requires costly funds. For this reason, this system is designed to help people diagnose skin diseases online, making it easier for sufferers to diagnose the diseases they suffer from by themselves. The method used is the fuzzy Tsukamoto method. Analysis of the introduction of the disease is carried out by identifying various symptoms of the disease. The types of diseases diagnosed include tinea versicolor [P001], scabies [P002], ringworm [P003], dandruff [P004], vitiligo [P005], pityriasis alba [P006], hives [P007], erythema multiforme [P008], acne [P009], keloids [P010], melanoma [P011], eczema [P012], boils [P013], measles [P014], psoriasis [P015], impetigo [P016], and herpes [P017]. Skin disease sufferers can diagnose their disease without consulting with a specialist directly. This system can be used as a substitute for a specialist in producing a diagnosis in the form of the name of the disease suffered by the system user (user). This system provides a solution for users regarding more economical disease diagnosis.

Abstract

The purpose of study This For analyze How the use of e-commerce can increase effectiveness sale to generation millennials in the digital age. With focus on two variables independent main , namely e-commerce platforms and digital marketing strategies, research This will to study How factors the influence variable dependent , namely effectiveness sales . Data collection methods used in study This is methodology survey . Author use approach study quantitative , especially cross-sectional models, based on developmental models or growth . Approach This aiming For collect comprehensive data with fast and descriptive development individual from time to time . The target population consists of from 500 students from various campus private sector in Jakarta, with group target specific is 120 students from several programs on campus this . Size sample of 120 students chosen using total sampling, where the size sample The same with size target population. From the hypothesis First until third results calculations assisted by SemPLS that There is influence significant and positive , then Success in leveraging e- commerce platforms and digital marketing strategies depends on a deep understanding of market and consumer dynamics, as well as the ability to adapt and optimize strategies according to platform characteristics and desired business goals . Considering the characteristics and preferences of the millennial generation who focus on technology, user experience, and trust, it is important for businesses and e- commerce platforms to continue to develop relevant and sustainable strategies. This will not only allow for increased sales conversions and brand awareness, but also to maintain customer loyalty in an increasingly competitive and dynamic market.

Abstract

AbstrakDalam era digital ini, peran energi listrik sangatlah penting dalam  kehidupan manusia. Selain dibutuhkan sebagai infrastruktur yang mendorong pertumbuhan ekonomi nasional maupun regional, energi listrik juga sangat dibutuhkan oleh masyarakat untuk menunjang keberlangsungan kegiatan sehari-hari serta faktor penting dalam upaya peningkatan kesejahteraan dan kenyamanan hidup. Karena energi listrik memiliki peran yang begitu penting dalam kehidupan, maka tentu tidak heran jika terjadinya suatu peristiwa mati listrik dapat menghambat banyak aktivitas dan kegiatan sehari-hari bahkan pada aktivitas atau kegiatan yang memanfaatkan jaringan internet.Dengan memanfaatkan teknologi UPS yang sudah ada, serta memanfaatkan perkembangan teknologi Revolusi Industri 4.0, dibuatlah sebuah perancangan alat berupa UPS yang dapat digunakan secara portabel, dimana UPS ini memiliki sistem berbasis IoT yang dapat menyediakan cadangan daya listrik secara otomatis yang terhubung pada sistem keamanan CCTV dan jaringan WIFI di rumah. Sistem kerja alat ini menggunakan jaringan internet sebagai pusat informasi antara alat dengan database Home Assistant Cloud yang digunakan. Sistem kerja alat ini memliki sensor yang bekerja secara sebagai pendeteksi tegangan dan arus yang keluar dan masuk pada modul UPS sesuai dengan prinsip kerja serta hasil yang dibaca oleh sensor.Penggunaan sensor INA 219 menghasilkan pembacaan nilai daya pada beban Wi-fi dan CCTV dengan rata-rata selisih 0,01 Watt. Sementara pada Modul PZEM017 menghasilkan pembacaan nilai daya pada beban Wi-fi dan CCTV dengan rata-rata selisih 0.6 Watt. Kedua pengujian tersebut menggunakan baterai dengan kapasitas yang sama sebesar 1000 mAh. Kata Kunci : Internet of Things , NodeMCU ESP8266, PZEM-017 DC, UPS , Sensor INA 219, Arus, Tegangan, Daya

Abstract

Energi menjadi komponen penting bagi keberlangsungan hidup manusia, saat ini dan beberapa tahun kedepan, manusia masih akan bergantung pada sumber energi fosil. Disatu sisi, manusia akan dihadapkan pada situasi menipisnya cadangan sumber energi fosil dan meningkatnya kerusakan lingkungan akibat penggunaan energi fosil. Melihat kondisi tersebut, sangat diperlukan penelitian yang secara khusus untuk mencari, mengoptimalkan dan menggunakan sumber energi alternatif. Penelitian ini bertujuan untuk merancang sumber energi alternatif yang murah dan mudah untuk diterapkan di kalangan masyarakat, khususnya masyarakat daerah terpencil di Indonesia yang belum dialiri oleh arus listrik dan juga bisa menjadi proses pembelajaran tentang pemanfaatan barang bekas (sampah) sebagai sumber energi alternatif yang terbarukan. Hasil penelitian ini menunjukkan, bahwa total waktu pengujian pada 3 buah tersebut, masing-masingnya berlangsung selama 30 menit, dengan 5 kali pengujian di setiap buahnya dan terbagi selama 6 menit setiap pengujiannya, perolehan hasil nilai rata-rata tegangan dan arus yang dirangkai secara seri (pada jeruk nipis 2,07V & 13,1mA), (pada mangga 2,27V & 9,9mA) dan (pada alpukat 2,24V & 12,4mA).
