<![CDATA[Various types of models student-centered learning has increase for this time. In addition to appropriate learning models, use media for learning is expected to improve student achievement. The purpose of this research is to determine whether the learning achievement student by using media power point in cooperative learning NHT better than just using cooperative learning NHT without media on the subject of hydrocarbons. The study population was the whole class X SMA Teladan with totaling 3 class. Samples were taken at random as much as 2 class and consists of 72 students. The data of student achievement in Chemistry obtained by providing multiple-choice test with 20 questions. Hypothesis testing is done right part t-test at a significance level of = 0.05. Results of data analysis obtained by the average value of the students taught using media power point and a model cooperative pembelajran NHT (class eksperimen1) was 72.08 ± 13.80 with an increase of 56.67%, while the average value of the students taught by implementing cooperative learning NHT (class eksperimen2) was 65.28 ± 9.41 to 40.56% increase. The results showed that an treatment by using media power point on cooperative learning model NHT better than the treatment only implement cooperative learning model NHT to improve studentâs achievement in Chemistry, with t-test (2.739) > t table (1.66883) for α = 0.05 and df = 68.]]>

<![CDATA[Abstrak Pengetahuan kimia ibu rumah tanggamenjadi faktor penting untuk mendukung perilaku dan perlakuan ibu rumah tangga terhadap semua jenis bahan kimia yang digunakan dalam kehidupan sehari-hari. Pengetahuan kimia ibu rumah tangga juga dapat membantu keluarga membuat keputusan terbaik untuk konsumsi yang sesuai dengan kebutuhan orang tua dan anak-anak. Tulisan ilmiah ini adalah hasil pengabdian Prodi Pendidikan Kimiadalam rangka LUSTRUM Dies Natalis UKI tahun 2018 kepada masyarakat Kelurahan Cawang, Jakarta Timur. Kegiatan tersebut bertujuan untuk meningkatkan pengetahuan kimia pada ibu rumah tangga kelurahan Cawang, Jakarta Timur, dalam kehidupan sehari-hari. Materi pembekalan diberikan melalui penyuluhan dalam focused group discussion(FGD) yang mencakup pengetahuan tentang kimia bahan makananterkait gizi keluargadengan GERMAS (Gerakan Masyarakat Sehat)dan pelatihan pengolahan sampah rumah tangga yaitu mengolah minyak jelantah menjadi sabun colek, mengubah sampah plastik menjadi hiasan lampu, dan membuat lilin aromaterapi dari lilin bekas.Tigapuluh ibu rumah tangga yang hadir memberi umpan balik bahwa mereka senang mendapat ilmu tentang gizi keluarga yang sesuai dengan kebutuhan dan juga akan mulai mengolah minyak jelantah menjadi sabun colek serta mengolah lilin bekas menjadi lilin aromaterapi dengan pewangi buatan sendiri yang berasal dari sampah bahan masakan berupa kulit jeruk nipis dan jahe. Kata kunci: pengetahuan kimia; GERMAS; ibu rumah tangga; olah sampah perkotaan; kelas ekonomi menengah Abstract Chemistry knowledge for housewives is necessary to support their behavior and handling on various everyday life-chemical material. The chemistry knowledge also helps the family to make wise consumption decisions based on family members’ need. This academicwritten describe the result of Cawang Urban VIllage’s community service which had been done by Chemistry Education Study Program in LUSTRUM Dies Natalis of UKI year 2018. The aim of the community service is to improve the chemistry knowledge of 50 housewives who live in Cawang Urban Village-East Jakarta based on everyday life. A material enrichmentwas conducted by socialization in focused group discussion. The material enrichmentabout food chemistry education on family’s nutrition through GERMAS program and training on domestic garbage processing i.e used cooking oil is processed become dab soap, plastic waste modification become lamp decoration, and aroma-therapy candle making from a used candle. The 30 housewives gave feedback that they were very happy to get the chemistry knowledge about appropriate nutrition intake to family members’ need, and will start to make dab soap fromused cooking oil and make their handmade fragrance from lime and ginger peel for homemade aroma-therapy candle.

<![CDATA[Pandemi Covid-19 yang terjadi di seluruh dunia telah membuat perubahan dalam banyak hal di kehidupan masayarakat. Secara khusus di Indonesia, berita tentang maraknya penyebaran virus covid-19 mulai pada bulan Januari 2020 hingga akhirnya awal Maret pemerintah mengambil keputusan yang sangat sulit dengan mengeluarkan kebijakan Pembatasan Sosial Berskala Besar (PSBB), di mana berbagai sektor terkhusus di bidang pendidikan diharapkan melaksanakan seluruh kegiatan secara online. Tidak terkecuali Perguruan Tinggi Universitas Kristen Indonesia turut mematuhi kebijakan yang dikeluarkan oleh pemerintah. Adanya rasa ketakutan yang mendalam pada masyarakat yang mendorong untuk menjaga diri dengan menerapkan protokol kesehatan dan juga menjaga kebersihan dengan mencuci tangan atau menggunakan hand sanitizer membuat masyarakat secara khusus di Jakarta berlomba-lomba untuk memiliki antiseptik pencuci tangan karena dinilai efektif membunuh kuman atau virus. Sehingga persediaan antiseptik ini pun langka dan melambung tinggi. Kondisi ini menjadi perhatian Universitas Kristen Indonesia sebagai Perguruan Tinggi yang berkomitmen menjalankan Tri Dharma Perguruan Tinggi yang salah satunya adalah Pengabdian kepada Masyarakat dan juga oleh dorongan kemanusiaan membantu pemerintah pada masa-masa sulit di saat pandemi covid-19, sehingga Universitas Kristen Indonesia melalui karya pengabdian para dosen di Prodi Pendidikan Kimia FKIP dan Fakultas Kedokteran bersama-sama dengan Lembaga Penelitian dan Pengabdian kepada Masyarakat (LPPM) melaksanakan kegiatan “Aksi UKI Perduli Dalam Rangka Pncegahan Penyebaran Virus Covid-19”. Dalam kegiatan PkM ini para dosen bekerja di laboratorium dengan mematuhi protokol kesehatan dalam rangka membuat atau memproduksi hand sanitizer sesuai dengan standar World Health Organization (WHO), dan selanjutnya mendistribusikan produk tersebut ke masyarakat melalui puskesmas-puskesmas dan kelurahan-kelurahan yang ada di Jakarta Timur. Sebanyak 2000 botol kemasan 100 mL hand sanitizer diproduksi dan didistribusikan oleh Universitas Kristen Indonesia melalui dua tahapan waktu. Kata kunci: Pengabdian kepada Masyarakat; Aksi Perduli; Hand Sanitizer; Pandemi Covid-19]]>

<![CDATA[The outbreak of the corona virus (covid-19) in Indonesia which continued to increase until early March 2020, eventually led the government to impose a large-scale system of social restrictions (PSBB) in the DKI Jakarta area and several other regions. The implementation of this system also automatically encourages education practitioners to carry out online learning. Teachers and students are forced to be ready in their implementation, although so far some schools have never done learning with an online system. Through this research, the researcher wants to analyze how effective the implementation of the learning system is from the teacher's perspective. The sample of this study was 35 teachers who teach at the primary school level from public and private schools in the North Jakarta area. The instrument used was a questionnaire distributed online using the ms.form link. Based on the data obtained, shows that the implementation of online learning has been carried out effectively seen from the readiness of the teacher, the ability to use applications, responses and benefits obtained]]>
