Abstract

Memasuki era Teknologi Informasi dan Komunikasi yang merambah hampir di semua lini kehidupan. Aktivitas manusia tidak dapat lepas dari sentuhan teknologi. ‘Aisyiyah Kota Tasikmalaya sebagai sebuah organisasi masyarakat sipil, belum merespons kondisi masyarakat yang hampir semua berbasis teknologi. Salah satu upaya dalam pengelolaan pengetahuan (knowledge management) ini dengan diselenggarakan sosialisasi pengenalan dan pelatihan pengelolaan Sistem Informasi ‘Aisyiyah (SIA) di wilayah Kota Tasikmalaya dengan harapan akan memperkuat kelembagaan ‘Aisyiyah sehingga mampu memberikan kontribusi kepada umat dan bangsa menuju Indonesia berkemajuan. Program ini direncanakan bekerja sama dengan Lembaga Penelitian dan Pengembangan ‘Aisyiyah (LPPA) Jawa Barat dan unsur serta jajaran Pimpinan Daerah ‘Aisyiyah (PDA) di wilayah Kota Tasikmalaya

Abstract

In the face of investment risk, investors generally diversify and form an investment portfolio consisting of several assets. The problem is the fiery proportion of funds that must be allocated to each asset in the formation of investment portfolios. This paper aims to study the optimization of the Markowitz investment portfolio. In this study, the Markowitz model discussed is that which considers risk tolerance. Optimization is done by using the Lagrangean Multiplier method. From the study, an equation is obtained to determine the proportion (weight) of fund allocation for each asset in the formation of investment portfolios. So by using these equations, the determination of investment portfolio weights can be determined by capital.

Abstract

Permasalahan polutan udara di area perkotaan tidak dapat diabaikan kembali dikarenakan sangat berdampak pada kehidupan manusia saat ini dan masa mendatang. Diperlukan media dan peranti yang dapat menyampaikan nilai kualitas udara dalam upaya meningkatkan kesadaran masyarakat bahwa pentingnya kualitas udara yang sehat. Dalam penelitian ini memaparkan rancang bangun alat ukur kualitas udara yang dapat menampilkan secara langsung pada Led Matrix P10 berbasis Arduino Mega 2560 dan terintegrasi dengan sensor PMS5003 untuk mengukur nilai PM2.5, sensor MICS6814 untuk mengukur konsentrasi NO2 dan CO, serta IoT digunakan sebagai fungsi database. Dengan menggunakan metode penelitian R&D (riset and development) luaran penelitian ini diharapkan dapat diterima oleh masyarakat seutuhnya. Informasi yang disajikan merupakan nilai standar setiap satuan pencemar dan kategori kualitas udara yang ditampilkan merupakan nilai yang telah di konversikan dengan satuan Indeks Standar Pencemaran Udara (ISPU) dengan tujuan untuk keseragaman informasi yang tersampaikan kepada masyarakat tentang tingkatan bahaya pencemar udara diantara tiga pencemar yang terukur. Hal ini ditinjau dari Peraturan Menteri Nomor P.14/MENLHK/SETJEN/KUM.1/7/2020 Tentang ISPU

Abstract

The classroom monitoring system with an android application based on the ESP8266 chip was created to solve problems on campus in finding unused rooms and to provide solutions to the problems of finding classroom thus far by using inefficient manual methods. The monitor system was made to determine the status of classroom usage with a passive infrared (PIR) sensor which functions to detect human presence in the room and a light sensor with a Light Dependent Resistor (LDR) to detect the use of the projector in the room. The two sensors are connected to the ESP8266 chip which is connected to a realtime database via the internet. The android application is specifically made to access monitoring data stored in a realtime database throughout it is connected to the internet. The results of this system test the PIR sensor reaches a maximum distance of 4 meters, a time delay of about 3 minutes, a reliable tool, and low cost.

Abstract

The system of remote monitoring electrical and control is a device that was created based on the problem of monitoring the need for electrical power connected to electrical devices and as a development of previous research. This monitoring and control system aims to determine the use of electric power at any time by reading the electric voltage and current with a voltage sensor and a current sensor respectively. The electrical power value that has been detected is forward to firebase and thingspeak, then transmit to the android application. This system is applied for usage monitoring of rooms connected to electrical devices as an indicator of room usage. The results of this system test are the minimum power load that can be detected is 80Watt, some loads still have a high error, but the system is able to detect at a certain distance effectively.

Abstract

Temperature and humidity control systems are widely applied in agriculture. To increase crop yields and make it easier for agricultural actors, especially in plant cultivation, it is important to innovate in the development of technology that is growing rapidly. This study aims to analyze the level of validity and reliability of temperature and humidity control devices in a cultivation test room based on Arduino Mega 2560 with the help of SPSS. The results of the analysis and test of temperature and humidity control devices, with a maximum coefficient of variation of 1.86% and a minimum reliability coefficient of 0.62.

Abstract

Fertile soil electronic soil is essential for plant growth, and its quality significantly impacts crop yields. To help farmers measure the nutrient content of their soil more easily and accurately, innovative technology is required. In this case study, we present the design of a soil nutrient measuring device for Nitrogen, Phosphorus, and Potassium (NPK) that focuses on cayenne pepper. The device uses NPK sensors that can detect soil nutrients when inserted into the ground. The data collected by the sensors is sent to an ARDUINO Nano V3 ATMEGA328P, where it is processed and displayed as analog signals on a screen. The device can be customized according to the user's testing or cultivation needs, making it a useful tool for optimizing plant growth and crop yields.
