<![CDATA[Hambatan praktikum fisika di tingkat SMA disebabkan oleh beberapa faktor.Salah satu faktor tersebut adalah masih jarangnya pelatihan penguasaan peralatan laboratorium bagi para guru.Akibatnya kreatifitas guru fisika dalam mempraktekkan konsep fisika yang diajarkan masih rendah sehingga diperlukan pelatihan perancangan alat peraga praktikum fisika.Tujuan kegiatan ini adalah memberikan pelatihan perancangan alat peraga praktikum fisika yang sedang up to date yaitu alat peraga pembangkit listrik energi terbarukan. Alat peraga praktikum pembangkit listrik energi terbarukan yang diberikan pada kegiatan pelatihan ini adalah pembangkit listrik tenaga angin (wind turbine). Pelatihan ini dapat dibagi menjadi dua tahap. Pertama, penjelasan komponen-komponen yang diperlukan dalam merancang alat peraga pembangkit listrik energi angin. Kedua, pengujian alat hasil rancangan yaitu dengan memvariasikan kecepatan angin yang datang pada alat peraga energi angin dan mengukur daya listrik yang dihasilkan. Pada kegiatan pengabdian kepada masyarakat ini para peserta(guru) dilatih merangkai komponen-komponen alat peraga. Namun para guru belum sempat melakukan pengambilan data dan menganalisis data hasil pengujian alat peraga secara mandiri. Namun demikian para guru telah diperagakan cara mengambil data variasi kecepatan angin terhadap daya keluaran. Adanya pelatihan perancangan alat praktikum fisika berupa alat peraga pembangkit listrik energi terbarukan khususnya pembangkit listrik tenaga angin bagi guru-guru fisika diharapkan dapat menjadi salah satu solusi hambatan pelaksanaan praktikum fisika di tingkat SMA. DOI: https://doi.org/10.26905/abdimas.v3i1.2251]]>

<![CDATA[The case of motorbike theft is one of the common problems in the community that needs to be found a solution. One of solutions to secure motorbikes from potential theft is to install smart vehicle technology (smart vehicl e). This paper describes the design of IoT vehicle safety systems using Arduino Mega microcontroller, fingerprint sensor, ESP8266 and Blynk applications on smartphones. For the experiment, this study uses an automatic transmission motorbike that represents the public motorcycle model. For research methods, this study uses three stages of design. The first stage is to compile the prototype hardware of a motorcycle security system using a fingerprint sensor, and a microcontroller. The second phase, IoT that uses a notification system on ESP8266-based smartphones and Blynk applications are designed. In the third stage, the security system and notification system sent via the smartphone are combined. In the results of the first phase of the trial, five people (whose fingerprints were registered and not registered) were involved to show the system was working as we expected. This means that even if the vehicle ignition is in the "ON" position, the motorcycle engine cannot be started using an electric starter method or using a crank start system. To be able to "start" a motorcycle engine, the user's fingerprint must be verified first. In the second phase of the trial,  notification via the Blynk application on the smartphone will show someone's fingerprint that started the motorcycle has been verified or not verified. Finally in the  final stage of the trial, information systems in the form of notifications on smartphones can be realized to inform users who are trying to start the motorcycle engine  have been verified or not verified. The results of this study are expected to become IoT applied references for motorcycle and other vehicle security systems]]>

<![CDATA[The analysis of the resistivity of a wire based on the Wheatstone bridge method and the Ohm law method in physics experiment module has been done. The analysis of the resistivity of a wire was done in a physics laboratory at UPNVJ engineering faculty. This topic was studied because there has been no experiment in the themed of electricity in the physics experiment module at the faculty of engineering UPNVJ. The most popular method applied to obtain wire resistivity value is the Ohm law method. In order to enlarge the understanding of the electricity concept, this research needed other method that can be used to find out the wire resistivity namely the Wheatstone Bridge method. This research aimed to obtain the resistivity value of Nichrome wire from two different methods. The methods were the Ohm law method and the Wheatstone bridge method. In Ohm law method, the wire length was subsequent varied. Then, the electric voltage value and an electric current were recorded. While in the Wheatstone bridge method, it was used circuit bridge. The value of the variable resistor was varied and the segment length metal plate was measured. The data were processed in order to obtain the Nichrome wire resistivity values by linear regression method. From Ohm law method and the Wheatstone bridge method were respectively obtained the value of Nichrome wire was ϱΔÏ=(2,875±0,005)x10-6 Ωm and ϱΔÏ=(5,00±0,25)x10-6 Ωm. The results of the two methods are match with the value of the standard of the Nichrome wire is Ï=1,0x10-6 Ωm. By using the two methods, it was expected that the students’ understanding of the electricity concept was increasingly widespread.]]>

<![CDATA[A numerical study of the solution of boundary value problems with the tridiagonal matrix approach has been done. The case studied is computing the electrical potential expressed by 1D Poisson’s equation with boundary conditions. The 1D Poisson’s equation are then discreted with the finite different method so as to form a system of linier equations. The system of non homogeneous linear equations that can be formed is a tridiagonal matrix. Then the matrix is solved by Gaussian elimination algorithm. On this study, the algorithm is implemented on three programming languages namely, Fortran, Java and MATLAB.]]>

<![CDATA[The Simpangan Village, especially RT 02/RW014 is located on Jl. Ciherang I Block C, North Cikarang, Bekasi; in early 2021 experienced a fairly large flood disaster. One of the reasons for this flood was the ineffectiveness of the household sewerage system and waste management in the area. Garbage is one of the important problems faced by every household, especially in densely populated areas such as residents of RT 02/RW014 Simpangan Village. Garbage originating from household activities that are not managed properly can have a bad impact such as the flood. One solution for handling garbage is to provide counseling and assistance on the importance of managing waste for the community. This paper aims to describe the results of community service activities, namely fostering housewives in RT 02/RW014 Simpangan Village, North Cikarang, Bekasi; related to the management of household waste into liquid organic fertilizer. The method of implementing the activity is in the form of online counseling and assistance in managing household organic garbage into liquid fertilizer. Liquid fertilizer processed by household organic waste is used directly for the gardening sector in the area. In addition, the management of liquid organic fertilizer has the opportunity to become a product that can be sold to help housewives get additional family income. Based on the results of the questionnaire, residents' responses to the implementation of this activity obtained an average score of almost 95% of the residents were satisfied. Globally, the results of this activity can help educate the public on the importance of a sustainable ecosystem.ABSTRAK:Desa Simpangan khususnya RT 02/RW014 terletak di Jl. Ciherang I Blok C, Kec. Cikarang Utara, Bekasi, pada awal tahun 2021 mengalami musibah banjir kiriman yang cukup besar. Banjir tersebut disebabkan salah satunya karena sistem saluran air limbah rumah tangga dan pengelolaan sampah di wilayah tersebut masih kurang efektif. Sampah merupakan salah satu masalah penting yang dihadapi oleh setiap rumah tangga khususnya daerah padat penduduk seperti warga RT 02/RW014 Desa Simpangan. Sampah yang berasal dari kegiatan rumah tangga yang tidak dikelola dengan baik dapat membawa dampak buruk seperti banjir tersebut. Salah satu solusi penanganan sampah adalah melakukan penyuluhan dan pendampingan pentingnya mengelola sampah bagi para warga masyarakat. Makalah ini bertujuan memaparkan hasil kegiatan pengabdian kepada masyarakat yaitu pembinaan para ibu Rumah Tangga di RT 02/RW014 Desa Simpangan Kec.
