Abstract

Waste bank systems such as Bank Sampah Mentari (BSM), located in Prupuh, Panceng, Gresik Regency, were created as a method of reducing waste. In its operation, the BSM management still has several difficulties such as the need to check the resident’s shelters, to administrative problems that are still done manually. Based on these problems, the implementation of a wireless sensor network on a smart trash bin using LoRa with the AES128 algorithm was made. The way it works is that the node device sends sensor reading data to the gateway every hour. The gateway will describe the incoming data, then upload it to MySQL and firebase before being accessed in the application. The test shows that the system can run well according to the plan where the farthest distance of LoRa is 300 meters. The average RSSI generated by node 1 is -95.78 dBm, node 2 is -112.57 dBm, and node 3 is -117 dBm. HC-SR04 ultrasonic sensor testing has an error of 0.795% (accuracy of 99.205%), while the MAX17048 sensor has an error of 0.3% with accuracy of 99.7%.

Abstract

Group cohesiveness is the degree to which a group wants to always survive and retain its members, or it can be interpreted as a measure of how attractive the group is to individuals, as a sense of responsibility and pleasure with its members in the group. One of the factors that can affect group cohesiveness is conformity. This research was conducted with the aim of knowing whether there is a relationship between conformity and group cohesiveness among members of the CB motorbike community at Pesanggrahan. The method used in this research is a correlational quantitative research method. The subjects used in this study were 150 members of the Motor City Bike Community in Pasanggrahan. Measuring tools used are conformity scale and group cohesiveness scale. The research data were analyzed using the product moment correlation test with the help of the IBS SPSS 24.0 for window computer program. The results of data analysis calculations show a correlation coefficient of 0.696 with a significant value of 0.00 (p <0.05), which means that there is a very significant positive correlation between conformity and cohesiveness in members of the motor city bike community. Kohesivitas kelompok merupakan tingkat sejauh mana kelompok ingin selalu bertahan dan mempertahankan anggotanya atau bisa diartikan ukuran seberapa menarik kelompok bagi individu, sebagai rasa tanggungjawab dan rasa senang dengan para anggotanya dalam kelompok. Salah satu faktor yang dapat mempengaruhi kohesivitas kelompok adalah konformitas. Penelitian ini dilakukan dengan tujuan mengetahui apakah ada hubungan antara konformitas dengan kohesivitas kelompok pada anggota komunitas motor CB di pesanggrahan. Metode yang digunakan dalam penelitian ini merupakan metode penelitian kuantitatif korelasional. Subjek yang digunakan dalam penelitian ini adalah anggota Komunitas Motor City Bike di Pasanggrahan yang berjumlah 150 orang. Alat ukur yang digunakan yaitu skala konformitas dan skala kohesivitas kelompok. Data penelitian dianalisis menggunakan uji korelasi product moment dengan bantuan program komputer IBM SPSS 24.0 for window. Hasil perhitungan analisis data menunjukkan nilai koefisien korelasi sebesar 0,696 dengan nilai signifikan 0,00 (p < 0,05) yang artinya terdapat korelasi positif yang sangat signifikan antara konformitas dengan kohesivitas pada anggota komunitas motor city bike.
