Abstract

The Liquid smoke is the dipersion of the Smoke in the air as the result of distillation or biomass pyrolysis of Cocos nucifera. This research was to know the effectiveness of Liquid smoke of Cocos nucifera to the growth of E. coli. The research was done in Microbiology Laboratory of the Medical Faculty of Jember University. This research is laboratorist experimental with used CRD (Completely Randomized design) with 3 times repetition. The data analysis used SPSS version 11 with Anova and Duncan. This research use some concentration, there are is 12,5%, 25%, 50%, and 100%, positiv control (klorin), and negatif control (aquades). The result of experiment by using Anova, it was kwon that Liquid smoke of in the concentration 12,5%, 25%, 50%, and 100%, to E. Colihave significance value is 0,00 (P<0,05), so every treatment has different result significantly. Whereas, the Duncan analysis showed 100% significantly different with another concentration, including positive and negative control. The 50% concentration has significant different with the 12,5% concentration, and the 25% concentration also has different result with K+ and K-. Whereas K+, K-, and 12,5% has didn’t different.That result proved that Liquid smoke can resist the growth of E. Coli.Key Word :Escherichia coli, Liquid Smoke.

Abstract

Ylang flower (Cananga odorata) is a plant that contains essential oils, flavonoids and saponins that are useful as a natural antibacterial. In this research, ylang flower antibacterial content obtained from a squeezed and boiled method. Serial concentrations used were 12,5%, 25%, 50% and 100%. While tetracycline 12.5% as the positive control and sterile distilled water as a negative control. There are differences in the effectiveness of antibacterial ylang flower of a squeezed and boiled method, it is known from the formation of inhibition zone on the test medium with Rancangan Acak Lengkap (RAL) 3x repetition. One Way Test results on freshly obtained ylang flowers calculated F value of 4.953 with 0.011 significance value, Ylang flowers being in the stew is not obtained F count. So in this research note ylang flower juice is more effective against Staphylococcus aureus growth compared with a decoction of ylang-ylang flowers.Keywords : Juice, Ylang flower (Cananga odorata), Staphylococcus aureus, Stews

Abstract

Pengaruh model pembelajaran discovery learning dengan media e-book berbasis smartphone terhadap ketuntasan belajar siswa. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran discovery learning dengan media e-book berbasis smartphone terhadap ketuntasan belajar siswa pada materi pencemaran lingkungan. Jenis penelitian ini adalah quasi experimental design. Populasi penelitian adalah semua siswa kelas VII di MTs. Zainul Hasan Balung tahun ajaran 2020/2021 dan sampel penelitian pada kelas VII B 19 siswa dan VII C 22 siswa. Pengambilan data dengan metode tes dan analisis data menggunakan uji Mann Whitney yang dioperasikan menggunakan SPSS. Data berdistribusi normal merupakan syarat mutlak sebelum melakukan analisis statistik parametrik, dikarenakan hasil dari uji normalitas menunjukkan data berdistribusi tidak normal sehingga menggunakan analisis statistik non parametrik. Berdasarkan hasil penelitian, pengambilan keputusan uji statistik non parametrik diperoleh nilai Asymp.Sig sebesar 0,413 maka dapat disimpulkan “hipotesis ditolak” artinya tidak terdapat pengaruh yang signifikan dari model pembelajaran discovery learning dengan media e-book berbasis smartphone terhadap ketuntasan belajar siswa. Melalui penelitian ini dapat disimpulkan bahwa diperlukan berbagai upaya untuk memunculkan lagi semangat pada diri siswa, guna meningkatkan motivasi dan minat belajar siswa. Sehingga semangat siswa akan tetap konsisten baik pada masa pandemi, maupun setelah masa pandemi. Menerapkan penggunaan media pembelajaran agar pembelajaran dikelas lebih menarik dan tidak membosankan, media e-book berbasis smartphone dapat digunakan sebagai variasi media pembelajaran. Kata Kunci: E-Book berbasis Smartphone, Ketuntasan belajar, Model Discovery Learning ABSTRACT The effect of discovery learning model with smartphone-based e-book media on student's learning compliance. This study aims to determine the effect of discovery learning learning model with smartphone based e-book media on student learning completeness on environmental pollution material. This type of research is a quasi-experimental design. The research population was all seventh grade students in MTs. Zainul Hasan Balung for the 2020/2021 academic year and the research sample was in class VII B 19 students and VII C 22 students. Data retrieval using the test method and data analysis using the Mann Whitney test which is operated using SPSS. Data with normal distribution is an absolute requirement before performing parametric statistical analysis, because the results of the normality test show that the data is not normally distributed so that non-parametric statistical analysis is used. Based on the results of the research, non-parametric statistical test decision making obtained the Asymp.Sig value of 0.413, it can be concluded "the hypothesis is rejected" meaning that there is no significant effect of the discovery learning learning model with smartphone based e-book media on student learning completeness. Through this research, it can be concluded that various efforts are needed to bring back enthusiasm in students, in order to increase students' motivation and interest in learning. So that the spirit of students will remain consistent both during the pandemic, and after the pandemic. Applying the use of learning media so that classroom learning is more interesting and not boring, smartphone based e-book media can be used as a variation of learning media.

Abstract

Proses pembelajaran terdiri dari melakukan kegiatan pembelajaran pada suatu lembaga pendidikan untuk membantu siswa mencapai tujuan dari pembelajaran. Pada proses pembelajaran guru sebagai sumber informasi perlu mengolah informasi tersebut supaya siswa bisa menerima informasi dengan benar dan jelas, untuk itu perlu adanya alat bantu, misalnya media pembelajaran Augmented Reality. Penelitian ini bertujuan untuk mengetahui peningkatan minat dan hasil belajar setelah menggunakan media Augmented Reality. Metode penelitian yang digunakan adalah kualitatif dengan jenis penelitian yaitu penelitian tindakan kelas. Penelitian ini menggunakan dua siklus, dimana setiap siklus terdiri dari perencanaan, pelaksanaa, pengamatan dan refleksi. Sampel penelitian yang digunakan adalah siswa kelas XI IPA MA Al-Misri Curahmalang Rambipuji sebanyak 28 siswa. Berdasarkan penelitian menunjukkan bahwa media pembelajaran Augmented Reality dapat meningkatkan minat dan hasil belajar siswa. Pada siklus I peningkatan minat sebesar 73% dan peningkatan hasil belajar sebesar 11%. Pada siklus II peningkatan minat sebesar 91% dan peningkatan hasil belajar sebesar 79%. Hal tersebut menunjukkan bahwa minat dan hasil belajar siswa meningkat setelah diterapkan media Augmented Reality.

Abstract

Tomat (Solanum lycopersicum L.) merupakan salah satu komoditas hortikultura yang bernilai ekonomis tinggi dan masih memerlukan penanganan serius, terutama dalam peningkatan hasil dan kualitas buahnya. Pada umumnya permasalahan yang sering dihadapi petani tomat di Indonesia adalah teknologi budidaya, mulai dari pemilihan benih, penanaman, pemupukan, pengendalian hama dan penyakit. Dalam pembudidayaan tanaman tomat (S. lycopersicum L.) para petani menggunakan pupuk kimia sebagai pupuk utama tanpa diimbangi pemberian pupuk organik. Hal tersebut jika dilakukan dalam jangka panjang akan berdampak tidak baik terhadap kesuburan tanah. Jenis penelitian eksperimen (True experiment research). Penelitian ini bertujuan mengetahui pengaruh pupuk bokashi fermentasi feses ayam terhadap pertumbuhan tanaman tomat. Hasil uji data dianalaisis staistik menggunakan one way ANOVA pada tanaman tomat (S. lycopersicum L.) diperoleh: 1) nilai F hitung sebesar 0,515 dengan nilai signifikansi 0,725 pada tinggi tanaman; 2) nilai F hitung sebesar 1,305 dengan nilai signifikansi 0,275 pada jumlah daun; 3) nilai F hitung sebesar 3,260 dengan nilai signifikansi 0,015 pada jumlah cabang produktif. Maka, disimpulkan bahwa perlakuan pemberian pupuk bokashi pada tinggi tanaman dan jumlah daun tidak berpengaruh nyata terhadap pertumbuhan tanaman tomat (S. lycopersicum L.), hal ini menunjukkan bahwa Ha ditolak dan Ho diterima, maka dalam hal ini tidak perlu dilanjutkan ke Uji Duncan. Sedangkan pemberian pupuk bokashi berpengaruh nyata terhadap pertumbuhan jumlah cabang produktif tanaman tomat (S. lycopersicum L.), hal ini menunjukkan bahwa Ha diterima dan Ho ditolak, maka dalam hal ini perlu dilanjutkan ke Uji Duncan.
