Abstract

Wuluh starfruit in Aceh commonly called "Boh Limeung" is a plant that is very often encountered, because star fruit is one of the spices in cooking. The Acehnese use star fruit as "SUNTI ACID", which is star fruit that is dried and then salted and used as a spice in cooking. The chemical compounds in star fruit leaves are flavonoids, saponins, sulfur, formic acid, steroid peroxides and tannins which are able to inhibit microbial activity and damage cell membranes so that, they can inhibit bacterial growth. The purpose of this study was to determine the potential of starfruit leaves (Averrhoal bilimbi L.) as antifungal candida albicans. The method used in this research is experimental laboratory. The treatments given in this study were 30%, 40%, 50%, 60% methanol extract concentrations. Then for the positive control (+), ketoconazole was used and for the negative control (-) aquadest was used. Based on the results obtained from the methanol extract of starfruit leaves (Averrhoal bilimbi L.) at concentrations of 30%, 40%, 50%, 60%, the average inhibition zone values were 17.5 mm, 17.35 mm, 17.95. mm, 18.77 mm. In Table 4.2, it can be seen that the largest inhibition zone is in the positive control (+) which is 23.5 mm while the negative control (-) is 0 mm.

Abstract

The study reveals to impact of 21st century education as a learning revolution. The research focus is directed at four sub variables; lesson planning; implementation of learning; learning assessment; and learning supervision. In this study, collecting data from various sources, the impact of 21st century education as a learning revolution are included in the category of several changes that must be made, such as: Planning the concept of conventional education; understanding education as an important part of efforts to create changes for better management of the life of the nation and state; Creating education that can adapt to the changing nature of globalization; Respond positively to the current changes in globalization and then direct them towards the concept of sustainable management, and create the concept of sustainable education. The results are expected to be input for other, regarding the real conditions in the field related to the impact of 21st century education as a learning revolution so that it can be taken into consideration in implementing the learning revolution in the 21st century. The impact of 21st century education in the learning revolution. This study is a literature review using a qualitative approach. Schools are part of the population in this study, and the sample uses a saturated sampling technique. Data were analyzed using a simple regression technique. The results of the study show that 90% of the impact of 21st century education influences the learning revolution. Positively changes in the flow of globalization then direct it to the concept of sustainable education management, thereby creating the concept of 21st century education.

Abstract

Penelitian ini membahas penerapan Algoritma Branch and Bound untuk memaksimalkan keuntungan produksi frozen food pada UMKM Moon Love. Dalam industri makanan, efisiensi produksi dan distribusi merupakan permasalahan yang sangat penting untuk diperhatikan, terutama untuk UMKM yang sering menghadapi keterbatasan sumber daya. Algoritma Branch and Bound digunakan untuk menyelesaikan permasalahan optimasi dengan membagi masalah menjadi sub-masalah yang lebih kecil dan mengeliminasi solusi yang tidak optimal. Penelitian ini menggunakan data sekunder yang diperoleh dari catatan harian UMKM Moon Love, kemudian menerapkan metode studi literatur untuk memahami konsep-konsep algoritma Branch and Bound serta model pemrograman linier lain nya. Hasil penelitian menunjukkan bahwa algoritma Branch and Bound memperoleh hasil yang optimal dalam menentukan jumlah produksi nugget, dimsum, dan risol pada UMKM Moon Love. Adapun keuntungan maksimal yang dihasilkan sebesar Rp. 5.840.000. Hal ini menunjukkan bahwa terjadi peningkatan keuntungan sebesar 21,2% dibandingkan dari sebelumnya. Sehingga dari penelitian ini dapat disimpulkan bahwa pentingnya metode optimasi dalam pengambilan keputusan untuk meningkatkan kinerja pada setiap usaha terutama pada UMKM Moon Love.
