Pengabdian kepada masyarakat dilaksanakan di desa kedung jaya, Babelan, Kabupaten Bekasi. Mayoritas penduduk Desa Kedung Jaya bermata pencaharian sebagai petani, beternak dan pedagang. Permasalahan yang terjadi di Desa Kedung Jaya adalah kurang memiliki budaya membuang sampah pada tempatnya karena tidak adanya penampungan sampah, sehingga sampah berserakan, tidak menjaga kebersihan dan kerapian lingkungan sekitar, dan tidak memiliki jadwal kerja bakti secara rutin. Solusi yang ditawarkan dengan permasalahan ini adalah melakukan kerja bakti secara rutin, membiasakan membuang sampah pada tempatnya dengan pengadaan bak sampah di dusun 3 dan 4, serta penyuluhan dalur ulang sampah dengan Metode 3R (Reduce, Reuse dan Recyle). Program pengabdian tersebut mendapat respon positif dikalangan warga desa, terbukti dengan keikutsertaan warga pada setiap program. Hasil program yang sudah terlaksana adalah lingkungan terlihat bersih, warga mulai membiasakan diri mengumpulkan sampah dan membakar di bak sampah yang sudah tersedia serta masyarakat mengenal pengetahuan mengenai dalur ulang sampai dasarkan 3R (Reduce, Reuse dan Recycle).

Corrosion is a decrease in the quality of a material or metal due to electrolyte reactions in the environment that affect the life of the material. Corrosion rate is the speed of propagation or speed of decline in the quality of a material with time. Corrosion processes occur in acidic environments, sea water, rain water, and soil are the result of chemical reactions that are also caused by electrochemical processes. The purpose of this study is to determine the corrosion resistance of aluminum metal to variations in the solution of Methanol (CH3OH). This study uses aluminum plates that will be immersed 5 days with a solution of Methanol (CH3OH). How to collect data by testing the Scanning Electron Microscopy (SEM) on each aluminum plate specimen that has been treated with corrosion by heating at a temperature of 60 oC. Methanol solution is one of the factors causing corrosion of metals. If in the free environment, air, temperature, and acidic substances are most commonly found as a factor causing corrosion. The increased corrosion rate is due to the higher concentration of the cause of corrosion. In this discussion Methanol as the concentration used, and aluminum as the metal tested.

Abstract LPG gas leaks are often not noticed by people around them, plus there is no special warning system that detects the LPG gas leak. That can increase the chance of fire. This study aims to build a LPG gas leak detection system as an early warning so that people are safer in using the gas for their daily activities. This system is built using the prototype method, with Wemos D1 EPS8266 as the microcontroller, and whatsapp as a platform to receive notification alerts. Then the result is that the system can send notifications via Whatsapp at online and realtime when there is an indication of an LPG gas leak. Keywords: Microcontroller, MQ-2 Censor, LPG Gas, Wemos D1 Abstrak Kebocoran gas LPG seringkali tidak disadari oleh orang sekitar, ditambah tidak adanya sistem peringatan khusus yang mendeteksi adanya kebocoran gas LPG tersebut. Hal itu dapat menambah kemungkinan kebakaran semakin meningkat. Penelitian ini bertujuan untuk membangun sistem pendeteksi kebocoran gas LPG sebagai peringatan dini agar masyarakat lebih aman dalam menggunakan gas tersebut untuk kesehariannya. Sistem ini dibuat menggunakan metode prototype, dengan wemos D1 EPS8266 sebagai mikrokontrollernya, dan whatsapp sebagai platform untuk menerima peringtan notifikasinya. Maka hasilnya sistem dapat mengirimkan notifikasi melalui whatsapp secara online dan realtime saat terindikasi adanya kebocoran gas LPG. Kata kunci: Mikrokontroller, Gas LPG, wemos D1, sensor MQ-2

AbstractOne form of development of interactive learning media is learning media using games. Because games are quite popular among teenagers, by building learning media using games, it is hoped that it can help increase learning motivation and attract interest in learning with a fun learning process. This educational game is called Hinterweltlern with the RPG (Role Playing Game) genre, where a story is presented based on the basic competency material at each level. Students will explore dungeons, and can access materials by completing objectives/missions, killing enemies, or reaching the checkpoint area. Each level session has a Boss that must be defeated by answering questions correctly about the material that has been given to advance to the next level. The research method used in this study is the Research and Development (P&P) method. This educational game is a hybrid game with the genres of Role Playing Game, Fighting, Fantasy, and Education using Unity 3D software, which replaces the Conventional Learning Activity method with a more interactive and interesting method, namely a Windows Platform educational game. The result of making this Educational Game of Appearance is in the form of a 3-dimensional Game, the player where the player will act as a certain character who runs the plot according to the storyboard that has been made. Players will be asked to explore dungeons/chapters to run quests or access materials. Keywords : Instructional Media; Games; RPGs; Unity 3D;

Noise is an undesirable sound from a business or activity in a certain level and time that can cause public health problems and environmental comfort. Noise occurs because there is a noisy source, a material delivery medium or air. The impact of noise in an area is of great influence to the health and well-being of people, animals and wildlife and disturbance to the natural ecosystem. For human health, noise can cause disturbances in the system of hearing and digestion, stress, headache, increased blood pressure and can reduce performance. Equipment used to conduct this research one of them is the Sound Level Meter which is the main tool in noise research. This tool is downloaded from the playstore app. SLM is used to measure noise intensity. The SLM used is a digital SLM capable of measuring effective sound pressure levels in decibels (dB). This tool measures noise with a scale between 30 ~ 100 dB. This research used qualitative method by conducting survey to Jl KH. Noer Ali West Bekasi to Jl. Wisma Asri Park Bekasi Utara. In this study using GIS with data collection method using Data Mining in Hierarchical clustering.

AbstractThe growth of plants requires watering the plants so monitoring is necessary. Monitoring is carried out for the process of watering plants running optimally according to plant needs based on soil moisture and room temperature. Soil moisture explains that it settles between the soil pores, this is also due to evaporation of the soil surface, transpiration and infiltration. The purpose of this research is to do watering using a jet irrigation system so that it is done automatically in watering the soil according to the humidity and temperature required for the plants. The important factor of soil moisture is influenced by factors including the quality of the soil used as agricultural land, namely the life of the biological elements contained in the soil including hosts, pathogens, and also various other microorganisms, greatly affecting soil moisture. Determine the amount of water flow that flows from the water source to the soil element in order to get the appropriate level of humidity. In this study, the authors used cayenne pepper and red chili as the object of research, where these plants can grow at an optimal temperature of 24˚C – 28˚C, so it is necessary to monitor temperature and soil humidity using Arduino sensors to create a jet irrigation system.

It is time for the application of Bandwidth Management to be carried out on an internet network that is experiencing a growing number of users and the required bandwidth. This study aims to implement bandwidth management in Onesnet Bekasi with the provisions of the distribution of bandwidth per user with a predetermined bandwidth limit according to the needs of Onesnet clients. Uneven bandwidth allocation and the available bandwidth is very limited, causing tug of war between Internet users on the same network so that the network lags. This research uses the Network Development Life Cycle (NDLC) method, to overcome the problem of bandwidth sharing, the Queue tree method is used. The result of this research is Onesnet Bekasi users get an upload and download bandwidth limit of 4 Mbps according to the comparison through Wireshark software. Then the results of the Quality Of Service (QOS) parameter testing were obtained with a throughput of 65.0997 b/s, a delay of 0.07, a packet loss of 0%, and jitter of 5 ms. Keywords: Manajemen Bandwidth; Quality Of Service; Network Development Life Cycle (NDLC); Throughput; Delay
