Abstract

In the 21st century technological advances can support the improvement of thelearning process. By utilizing existing technology, teachers need to pay attention to aspectsof learning media in supporting the learning process. This research is an R&D (Researchand Development) development research which aims to produce appropriate and feasibledevelopment of natural science teaching materials (IPA) in junior high schools accordingto the validation results of material experts, media experts and student responses. Studentsbecome interested in studying and understanding the material provided.This development research leads to the ADDIE development model which consists of fivestages in research, namely: 1) Analysis, 2) Design, 3) Development, 4) Implementation, 5)Evaluation. The technique of using data uses student response questionnaires. Data analysisused qualitative and quantitative descriptive analysis techniques

Abstract

Motivation to learn is a feeling that occurs because of the impulse within or outside the human being to be excited about achieving a goal, as well as being a force that can influence hopes and ideals to be achieved. In this study, it was discussed about the material of the human digestive system of biology subjects that use the Problem Based Learning model associated with MindMapping to encourage students to have high motivation which will have a positive impact on achievement or learning outcomes. Differences with conventional learning models or lectures still have to be updated with problem-based learning models. Validation of this model uses a comparison between learning implementations that use experimental and control classes. Thecalculation results of this model are very significant using several inferential statistical tests. The use of this statistical test can obtain valid results. The results of the experimental class are 92.50 and the control class is 78.75.

Abstract

Di Indonesia, Ubi kayu (Mahinot esculenta) merupakan produk pertanian terbesar kedua setelahberas, sehingga pasokan ubi kayu berpotensi menjadi bahan baku penting untuk berbagai produkpangan. Ubi kayu merupakan bahan makanan yang biasa dikonsumsi oleh masyarakat Indonesia.Stick Cassava merupakan salah satu bentuk diversifikasi makanan berbahan pangan lokal ubikayu. Diversifikasi pangan ini bertujuan untuk merubah pola konsumsi masyarakat yang harusdisertai dengan teknologi pengolahan pangan. Adapun tujuan dalam penelitian ini adalah untukmelihat pengaruh stik proporsi tepung ubi kayu F1 (Tepung ubi kayu 10%, tepung terigu 90%),F2 (Tepung ubi kayu 20%, tepung terigu 80%), F3 (Tepung ubi kayu 50%, terigu 50%), F4(Tepung ubi kayu 70%, tepung terigu 30%), F5 (Tepung ubi kayu 90%, tepung terigu 10%)terhadap sifat kimia dan organoleptik. Menggunakan Rancangan Acak Lengkap (RAL) faktortunggal, dengan lima taraf perlakuan proporsi tepung ubi kayu dengan tiga kali ulangan, sehinggadidapatkan 15 Perlakuan. Data yang didapatkan setelah perlakuan penelitian uji organolepticpada masing-masing variable dimasukkan dalam tabel untuk dianalisa Uji Friedman. Sedangkanpada perlakuan penelitian uji sifat kimia dianalisa dengan uji ANOVA dan jika terdapatperbedaan dianalisa dengan Uji Tuckey. Perlakuan terbaik dianalisa menggunakan indeksefektifitas. Hasil dari penelitian menunjukkan pengaruh tepung ubi kayu terhadap kualitas sifatkimia yaitu kadar air kadar air 8,63%, kadar abu 2,875%, organoleptik warna 3,72, rasa 3,92,dan tekstur 4.

Abstract

Mie basah merupakan salah satu produk pangan yang berbentuk kecil dan memanjang yang dapat diperoleh dengan proses pencetakan dan dilanjutkan dengan perebusan. Mie basah dapat digolongkan sebagai produk yang memiliki kadar air yang cukup tinggi yaitu 60%. Pada umumnya, mie basah terbuat dari tepung terigu yang mana protein tepung terigu sangat terbilang cukup rendah untuk memenuhi kandungan gizi yang dibutuhkan oleh tubuh yaitu protein, maka dari itu penambahan tepung udang rebon dapat meningkatkan nilai gizi protein terhadap mie basah. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan tepung udang rebon terhadap karakteristik fisik, kimia dan organoleptik dan mendapatkan perlakuan terbaik dari penambahan tepung udang rebon pada mie basah. Metode yang digunakan dalam penelitian ini yaitu Rancangan Acak Kelompok (RAK) non faktorial dengan 5 perlakuan 3 kali ulangan, sehingga diperoleh 15 kali percobaan. Dengan perlakuan perbandingan tepung terigu dan tepung udang rebon. Analisa yang dilakukan meliputi Analisa fisikokimia meliputi kadar air, kadar protein, uji tekstur dan organoleptik meliputi warna, aroma, dan rasa. Hasil penelitian terbaik terdapat pada perlakuan P4 (60% tepung terigu : 40% tepung udang rebon) dengan hasil uji fisik kimia Analisa kada air 49,68%, kadar protein 7,66%, uji tekstur 0,058N dan uji organoleptik warna 4,08 (suka), aroma 3,24 (agak suka), dan rasa 3,6 (agak suka).

Abstract

The study aims to find a comparison of the effectiveness of interactive learning media with powerpoint media on the results of studying the genetic substance of class XII students at Hang Tuah 4 Surabaya high school. The method used in this study is an experiment with research design is a nonfunctional control design group. The population in this study is 33 XII High School Science students Hang Tuah 4 Surabaya. The sample used in the study is to group into two large groups by odd absenbs and even Numbers.Research obtained from: (1) the average student study results from both groups, experiment groups 1 and experiment groups 2, were obtained that the average for experiment groups 1 of 80,63, for experiment groups 2 of 65.88. (2) based on the t test results on both groups, the result of thitung gained by 0.017, in which case it is stated that thitung is smaller than the ttabel 0.05. Based on the average results of student study and hypothetical tests made by researchers it results that the use of interactive learning medium suggests a postif and is more effective in the increased study of students the genetic substance of a class XII Science 2 High School Hang Tuah 4 Surabaya

Abstract

Trichoderma viride adalah patogen dalam dirinya sendiri dan dapat menyebabkan jamur busuk hijau pada jamur yang dibudidayakan. Pada awalnya koloni T. viride berwarna putih dalam media Potato Dextrose Agar (PDA), setelah dibiarkan lama berkisar 3-4 hari koloni tersebut akan berwarna hijau. Penelitian ini bertujuan untuk mengetahui “Uji aktivitas ekstrak jantung pisang (Musa paradisiaca formatypica) sebagai antifungi Trichoderma viride pada media tanam baglog jamur tiram var. Greyoyter sebagai sumber belajar mata kuliah mikrobiologi. Penelitian ini menggunakan metode uji difusi cakram dengan melihat zona hambat yang ditandai dengan adanya zona bening di sekeliling kertas cakram yang menggunakan 4 konsentrasi meliputi 0%, 50%, 75% dan 100% masing-masing perlakuan diulang sebanyak 6 kali. Diameter zona hambat yang ditandai dengan adanya zona bening disekeliling kertas cakram akan diukur dengan menggunakan jangka sorong dan hasil data tersebut akan dianalisis secara deskriptif. Hasil analisis menunjukkan adanya perbedaan zona hambat yang ditandai dengan adanya zona bening disekeliling kertas cakram dengan konsentrasi 100% rata-ratanya 23.96 mm sedangkan pada konsentrasi 50% rata-ratanya 19.76 mm.
