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.

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

Indicators are substances that can be used to show the properties of a substance through a special change in its color. The types of plants used in this study as natural indicators are found in the surrounding environment for example purple sweet potatoes (Ipomea Batatas L) and butterfly pea (Clitoria Ternatea L). This research was conducted in 5 stages: 1) cut the purple sweet potato and butterfly pea into small pieces and then mash until smooth: 2) pour 5 tablespoons of alcohol and then leave until it settles; 3) pour the extract on 3 test tubes to test acid, base, and control; 4) drip the test solution on 2 test tubes; 5) then do testing to identify discoloration in purple sweet potato extract and butterfly pea a large amount of anthocyanin content in butterfly pea (Clitoria Ternatea L) affects the results of acid and alkaline testing so that the test results on butterfly pea extract (Clitoria Ternatea L) show a clear change in color. The purpose of this study is to identify the effectiveness of purple sweet potato extract (Ipomea Batatas L) and butterfly pea (Clitoria Ternatea L) as natural indicators of acid-base so that it can be used as an alternative learning medium.

Abstract

This study aims to determine the identification of acid-bases with natural indicators. This, is done because acid-base testing uses a lot of litmus paper. In dragon fruit extract and turmeric extract, there is a more concentrated color pigment content to determine the acid-base concentration. So we want to increase its sensitivity to detecting acid- bases. The method used in this study is experimental. The results of the study can be used to assist the public in knowing the benefits of dragon fruit and turmeric to detect acid-base solutions.

Abstract

Plants or plants are living things just like humans and animals. Plants also move which aims to show irritability and to respond to the stimuli it receives. Movement in plants is divided into several categories, one of which is the motion of tropism, which is also divided into more specific movements. This writing aims to find out and study the mechanism of motion of the wijaya kusuma flower. Wijaya Kusuma Flower Plants are plants that have special movements and are different from the movements of other plants. Most people do not know that the movement of the wijaya kusuma flower plant is called scototropism. This motion can also be said to be negative phototropism because the plant will move away from the sun when the light comes close to the plant. One of the characteristics of the Wijaya Kusuma flower itself is that it can only bloom at night for between 1 and 2 hours and will wither the next morning.
