Abstract

Pembuatan alat ini bertujuan untuk membuat sebuah alat penyiraman dan pemupukan tanaman bawang merah secara otomatis yang diterapkan langsung pada greenhouse berukuran 2x1 meter berbasis Internet of Things menggunakan Arduino Uno. Dalam pembuatan alat menggunakan beberapa komponen yaitu Soil Moisture Sensor (sensor kelembaban), Real Time Clock (RTC), Mikrokontroller ATMega328, NodeMCU ESP8266 ESP-01, dan smartphone. Cara kerja dari alat dapat melakukan penyiraman bawang merah berdasarkan kondisi tanah yang dibaca oleh kedua sensor sama-sama dalam kondisi kering, dan untuk pemupukan alat akan beroperasi secara otomatis setiap Senin pukul 10.00 WIB dan akan berlangsung selama 60 hari monitoring. Pemberitahuan berupa notifikasi akan muncul pada smartphone pengguna melalui aplikasi Blynk sebagai monitoring jarak jauh dari sistem dan Liquid Crystal Display (LCD) sebagai penampil data untuk monitoring jarak dekat. Hasil pengujian alat menunjukkan bahwa sistem sudah berjalan dan bekerja dengan sangat baik seperti yang diinginkan.Kata kunci: Internet of Things, Penyiraman dan Pemupukan, Mikrokontroller ATMega328, Blynk The purpose of making this tool is to make an automatic watering and fertilizing tool for shallot olants that is applied directly to a 2x1 meters greenhouse based on the Internet of Things using Arduino Uno. In making the tool, several components are used, namely Soil Moisture Sensore (humidity sensor), Real Time Clock (RTC), ATMega328 Microcontroller, NodeMCU ESP8266 ESP-01, and smartphone. The workings of the tool can be watering shallots based on soil conditions that are read by both sensors both in logic 1 or dry, and for fertilization the tool will operate automatically every Monday at 10.00 WIB and will last for 60 days of monitoring shallot plants. Notifications is the form of notifications will appear on the user’s smartphone through the blynk application as remote monitoring of the system and Liquid Crystal Display (LCD) as a data viewer for close monitoring. The test result of the tool show that the system is running and working very well as desired. Keywords: Internet of Things, Watering and Fertilization, ATMega328 Microcontroller, Blynk

Abstract

The purpose of this article is to analyze the effect of student perceptions about the role of micro teaching courses on student teaching readiness. This type of research is quantitative descriptive. The population of this research is the 2014 UNP FE Economics Education students who have completed the micro teaching course and the Education Field Experience Program course totaling 84 people. The sampling technique is saturated sampling (total sampling) so that the entire population is sampled. Research data are primary data collected by questionnaire. Instrument testing uses validity and reliability tests. Data were analyzed by descriptive and inductive analysis using normality test, heterocedasticity test, hypothesis testing using simple regression, t test and coefficient of determination with α = 0.05. The results showed that there was a significant and positive influence between students' perceptions of  the role of micro teaching courses on student teaching readiness, namely sig 0,000 <0,05. Keywords: Perception, Role, Micro Teaching, Teaching Readiness

Abstract

Edible film is a thin plastic with a thickness of less than 0,25 mm and serves to protect food products. This study aims to determine the effect of adding carrageenan to edible film made from jackfruit seed starch (Artocarpus heterophyllus) on thickness, tensile strength, biodegradation and functional group analysis using the FTIR technique. This research was conducted by varying the concentration of carrageenan used, namely 0%, 0.5%, 1%, 1.5% and 2%. Based on the results of the analysis carried out, the addition of carrageenan affects the thickness, tensile strength and biodegradation of edible films. The maximum tensile strength was found in the addition of 1.5% carrageenan, which was 13.315 MPa, while the thickness and biodegradation increased with increasing carrageenan concentration. The tensile strength and thickness values obtained on the edible film have met the JIS ZI 707 standard edible film.

Abstract

Greening along roads can be an alternative solution to overcome air pollution in urban areas. Direct contact of plants with pollutant particles in the air will affect the condition of plants, especially on leaves. Knowledge of morphological characteristics and stomata on leaves that have the potential to absorb pollutants is the basis for understanding plant responses to environmental changes. This research is descriptive research conducted in September-December 2021 with leaf samples taken in the area of ​​PT Semen Padang, Padang State University, and Andalas University forests. Data were analyzed by t test level of 5%. The results showed that the morphological characteristics of trembesi leaves in the PT Semen Padang and Padang State University areas had significant differences in the aspects of the number of leaflets, leaf length, leaf width, not significantly different in the length of the mother petiole and the number of leaf branch bones and the characteristics of the stomata did not show any difference which is evident from the aspect of stomata length and stomata density. The morphological characteristics of trembesi leaves in the Padang State University and Andalas University forests showed significant differences in the length of the mother petiole, the number of leaflets, and the number of leaf veins, there was no significant difference in leaf length and leaf width and showed a significant difference in the aspect of stomata length, but did not show a significant difference in terms of stomata density. Morphological characteristics of trembesi leaves in the PT Semen Padang area and Andalas University forest showed significant differences in the length of the mother petiole, number of leaflets, leaf length, leaf width, and number of leaf veins and did not show significant differences in terms of stomata length and stomata density.
