The demand for energy is inversely proportional to the current amount of energy in Indonesia. In order to face this problem, it is necessary to develop renewable energy sources. This study was conducted to analyze enzymes effect in the Chlorella pyrenoidosa hydrolysis, analyze yeast effect and the fermentation time of Chlorella pyrenoidosa on the bioethanol produced. The variables used are variation of Î±-amylase enzyme concentration of 25%, 35%, 45% (v/w), and variation of yeast concentration of 5%, 10%, 15% (w/v) and fermentation time of 7, 9, 11 days. From the analysis conducted, the highest glucose content was 13.119%, which was in the variation of 45% (v/w) Î±-amylase enzyme concentration. The amount of enzyme concentration used was in accordance with glucose production. The highest bioethanol was obtained with a sample involving 10% (v/b) yeast fermented for 9 days, which amounted to 27%.

In order to trigger various penetrations in the field of mathematics, researchers conducted a research related to learning mathematics which aims to describe the process of constructing geometric concepts with the cultural context of Damar Kurung in terms of gender based on APOS theory using a qualitative-descriptive approach. Data analysis uses primary data in the form of student work, observations and interviews. The sampling technique used purposive sampling with the criteria of the student concerned having good communication skills. The results showed that based on the percentage of female students, it was much better, namely 81.25% compared to boys, at the scheme stage it only reached 5.8% in the first question, while in question number 2 the percentage of male students in the scheme stage was only reached 11.7%, very far compared to women whose percentage reached 68.75%. The percentage difference is 57.05%. With this percentage, it can be concluded that gender is one of the influences and is the focus for re-doing research related to testing how much influence gender has on solving ethnomathematics-based problems.

The research problem is focused on the mathematical concept of number material contained in the Qur'an. The purpose of the research is to find out the mathematical concept of number material in the Qur'an is true. This research was conducted using the Library Research method. The results of the research are arranged in a narrative based on the study process of various sources in journals, books and other sources, which are in accordance with the issues discussed. Indeed, there are many studies contained in the Qur'an that explain the concept of mathematics. Therefore, to study the Qauniyyah verses in the Qur'an, mathematics is needed. Thus mathematics is also able to provide an approach in understanding the verses of Qauniyyah because mathematics is a science that plays an important role in education, sometimes referred to as the "queen of knowledge" and "servant of knowledge", because it serves as the basis for the development of other sciences. Mathematical concepts are very important because when students understand a concept, students can remember the math lessons they have learned.

Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir lateral siswa berdasarkan Adversity Quotient (AQ) dalam pemecahan masalah geometri. Penelitian ini menggunakan jenis penelitian deskriptif kualitatif dengan subjek terdiri dari 30 siswa kelas XII MIPA 4 di SMAN TAMANAN. Subjek dipilih berdasarkan tipe Adversity Quotient (AQ) yaitu quitters, campers, dan climbers. Pengumpulan data pada penelitian ini melalui angket Adversity Quotient (AQ), tes kemampuan berpikir lateral, catatan lapangan, dan wawancara. Hasil penelitian ini menunjukan siswa dengan Adversity Quotient (AQ) tipe quitters cenderung mudah menyerah dalam menghadapi permaslahan sehingga hanya memenuhi indikator 1. Siswa dengan katagori Adversity Quotient (AQ) campers sudah berhasil menemukan lebih dari dua cara penyelesaian meskipun belum berhasil menyelesaikanya dengan baik sehingga siswa campers hanya memenuhi dua indikator yakni indikator 1 dan 2. Sedangkan siswa dengan katagori climbers memenuhi semua indikator berpikir lateral sebab siswa climbers mampu menyelesaikan soal tes dengan menggunakan lebih dari satu cara dan mampu menjelaskan langkah-langkah penyelesaianya dengan tepat.
