<em>Physics is one of the sciences that studies concepts, laws, formulas, and also real and abstract phenomena. Too many formulas in physics that must be understood by students, make students feel difficult and less enthusiastic in learning physics. One of the material that makes students like to forget is the material about unit conversions where the number of units that need to be remembered are units of length, acceleration, speed, energy and others. To solve this problem, it is necessary to make an application in the android system that can help in unit conversion and easily accessible. The method that will be used in this research is Research and Development (R&amp;D) using the ADDIE Model. Through the ADDIE Model cycle, they are: (1) Analysis, (2) Design, (3) Development, (4) Implementation and (5) Evaluation will be developed in this application. The results of the feasibility test from material experts are based on three aspects of assessment, namely the aspect of language, suitability of concepts and illustrations, which is in the feasible category with a total percentage of eligibility of 79,76%. Meanwhile, based on the results of the media expert feasibility test are based on three aspects of assessment, namely graphics, program processing and usage are in the very feasible category with a total percentage of eligibility of 88,89%.</em>

<p>Metode <em>fuzzy c means clustering</em> adalah salah satu teknik pengelompokkan data dalam satu klaster ditentukan oleh pusat <em>cluster</em> yang akan menandai lokasi rata-rata untuk tiap klaster. Tujuan dari penelitian ini akan dibahas tentang penerapan metode fuzzy c means cluster dalam pengelompokkan provinsi Indonesia berdasarkan indikator kesejahteraan rakyat. Berdasarkan hasil analisis pengelompokkan <em>fuzzy c means </em>dengan 2 klaster diperoleh fungsi objektif yang konvergen pada iterasi ke-18 adalah sebesar 130,7085. Pada klaster 1 yang dikategorikan sebagai kelompok kurang sejahtera terdiri dari 18 propinsi dan klaster 2 adalah kelompok sejahtera, terdiri dari 16 propinsi.</p>

<p>The population of Indonesia from year to year has increased. The increase in population must also be accompanied by increased economic growth in Indonesia. The increase in economic growth in Indonesia is marked by the reduction in the number of poor people in Indonesia. In addition, the increase in economic growth is reflected in the equitable distribution of public income in the country. Even though there are still many Indonesian people who are not yet prosperous in economic terms. To overcome, it is necessary to have clustering and characteristics of 34 provinces in Indonesia by implementing the Modification Maximum Standard Deviation Reduction (MMSDR) graph clustering algorithm. The data used are indicators of public welfare in 2017 obtained from the Central Statistics Agency. There are 9 indicators of community welfare used in this research. There are four stages in the MMSDR algorithm namely the "MST", "Subdivide", "Biggest Stepping" and "Create Clusters" processes. The results of this study can be seen from the distance between the nodes or between one province and another province produced 22 clusters. From the cluster results obtained using the MMSDR algorithm on welfare data, there are many clusters formed with cluster members formed at most two nodes (province).</p><p> Keywords: MMSDR, Clustering, Welfare of People</p>

Minyak bekas pakai (jelantah) merupakan minyak tumbuhan yang sudah digunakan untuk menggoreng. Penggunaan minyak bekas pakai mengakibatkan nilai ekonomis minyak tersebut turun dibanding minyak yang belum digunakan. Disamping itu, dengan sifat karsinogenik minyak bekas pakai sangat berbahaya bagi tubuh. Pemanfaatan minyak jelantah belum dilakukan secara optimal, karena banyaknya minyak bekas pakai yang sudah beberapa kali digunakan oleh restoran, kemudian setelahnya hanya dibuang begitu saja, tidak dimanfaatkan untuk produk lainnya. Proses pembuatan pengharum ruangan dari minyak goreng jelantah menjadi alternatif penyelesaian masalah yang patut dipertimbangkan. Pada pembuatan pengharum ruangan, minyak bekas pakai ini digunakan sebagai pengganti natural oil, yakni bahan utama untuk pengharum. Kegiatan pengabdian masyarakat melalui penyuluhan pembuatan pengharum ruangan dari minyak jelantah, dilakukan terhadap Ibu-ibu PKK Perumahan Pamulang Park Residence, Pamulang Barat, Kota Tangerang, Banten. Penyuluhan dilakukan dengan metode ceramah dan demo langsung di depan peserta kegiatan. Hasil yang diperoleh dari kegiatan ini adalah peserta dengan rasa suka cita ikut serta dalam demo kegiatan pembuatan minyak bekas pakai (jelantah) untuk pengharum ruangan. Peserta pun merasa senang karena bertambahnya pengetahuan tentang pemanfaatan minyak jelantah. Harapannya dengan melakukan kegiatan penyuluhan ini, maka Ibu - Ibu PKK pada perumahan tersebut dapat ikut serta dalam upaya meningkatkan daya saing wilayahnya dengan memanfaatkan minyak jelantah.

The use of cooking oil affects the economic value of the cooking oil lower than unused oil. Besides that, the carcinogenic nature of used oil is very dangerous for the body. Utilization of used cooking oil has not been carried out optimally, because of the amount of used oil that has been used several times by restaurants, and afterward only available just like that, is not used for other products. The process of making room air freshener from used cooking oil becomes an alternative solution to the problem raised. In the manufacture of air fresheners, used oil is used as a substitute for natural oils, which are the main ingredients for fragrances. Community service activities through counseling on the manufacture of air freshener made from used cooking oil were carried out on PKK women in Pamulang Park Residence, Pamulang Barat, Tangerang City, Banten. Counseling was conducted using the lecture and demo method directly in front of the activity participants. The results obtained from this activity were participants who liked to take part in the demonstration of used cooking oil (waste cooking oil) for air freshener. The participants were happy because they were adding knowledge about the use of used cooking oil. It is hoped that by conducting this outreach activity, PKK ladies in this housing can participate in efforts to improve the competitiveness of their region by using used cooking oil.
