The results of Integrated Science learning for Class VIII Boys at SMP IT Darul Ikhlas Al-Islami were only 18.75%, which reached the minimum limit criteria set by the school, namely 74. This was caused by several factors, such as students being lazy to ask the teacher if the subject matter they were learning was do not understand, and lack of enjoyment of reading science learning material from within students. To overcome these problems the researchers tried to apply the Problem Based Learning (PBL) model. This study aims to improve the learning outcomes of class VIII students of SMP IT Darul Ikhlas Al-Islami. This research method is classroom action research (CAR). This research was conducted in 3 cycles, each cycle consisting of 2 face-to-face meetings and 1 evaluation. The results of this class action research can be seen from the average value increasing from 30.51 in cycle I to 52.42 in cycle II, and to 80.62 in cycle III. While seen from the completeness of student learning from 0% in cycle I to 37.5% in cycle II, and to 75% in cycle III.

Fruit peel waste, so that it is not problematic for the environment and health, can be used as a source of eco enzyme raw materials, which are the result of fermentation of fruit/vegetable residue, sugar, and water. Eco enzymes can be made by mixing organic waste, such as fruit and vegetable waste, with sugar and water in a ratio of 3: 1: 10. Basically, all fruit and vegetable waste can be used as raw material for making eco enzymes. The service activity of processing fruit peel waste into Eco-enzyme invites students to handle waste in a simple way around the school. This service activity is carried out through group practice. Making eco enzyme invites students to use this liquid as a natural cleanser, one of the experiments to handle the waste. Using fruit peel waste as an eco enzyme as an alternative to cleaning fluid adds insight and skills in processing fruit peel waste into cleaning fluid.

Umbi-umbian merupakan komoditi dalam negeri yang mengandung karbohidrat. Komoditi ini ternyata dapat digunakan sebagai bahan pangan fungsional yang sebelumnya hanya digunakan sebagai sumber energi saja. Hal ini terjadi karena kurangnya informasi mengenai sifat fungsional yang dapat dimanfaatkan dari umbi ini. Artikel ini dibuat dengan tujuan sebagai informasi bahwa umbi ini selain sebagai sumber energi juga dapat memberi manfaat bagi kesehatan. Metode dari penelitian ini berdasarkan studi literatur dari jurnal maupun literatur ilmiah lainnya. Dari penelusuran literatur ternyata sifat fungsional tidak hanya berasal dari umbi saja namun dengan pengolahan juga dapat mempertahankan bahkan meningkatkan nilai fungsional ini. Senyawa fungsional yang terdapat dalam umbi-umbian berupa senyawa bioaktif. Beberapa senyawa bioaktif yang terdapat dalam umbi-umbian diantaranya saponin, protein bioaktif, senyawa fenolik, glikoalkaloid, asam fitat, karotenoid, dan asam askorbat. Kandungan ini umumnya banyak terdapat pada umbi-umbian yeng belum dibudidayakan secara khusus oleh masyarakat diantaranya discorea, colocasia ataupun maranta. Beberapa proses pengolahan yang dapat dilakukan untuk meningkatkan sifat fungsional pada umbi-umbian khususnya pati adalah pati resisten, modifikasi dan Microwave Assisted Extract (MAE). Sifat fungsional yang terdapat dalam umbi selain terkandung dalam umbi juga dapat berasal dari proses pengolahan yang dilakukan dalam umbi-umbian ini.

Garlic (Allium sativum L.) is an important commodity with various benefits, both as food and medicine. One of the biggest challenges is the spread of diseases in garlic plants, which are often transmitted through bulbs or seeds used in planting. The initiation stage is the initial step of in vitro culture to obtain explants that are free of microbes and start early growth. Materials commonly used for sterilization of garlic explants are detergent, alcohol, and Clorox. Eco-enzyme is a result of the fermentation of fresh fruit waste containing bioactive compounds, such as organic acids and enzymes, which have the potential to be used as natural sterilization materials. The purpose of this study was to make eco-enzyme as a sterilization material for explants from fruit skin waste and to obtain the right explant sterilization method in in vitro culture propagation using eco-enzyme. A total of five sterilization methods have been tested in the Tissue Culture Laboratory of the Payakumbuh State Agricultural Polytechnic. The sterilization materials used were 70% alcohol, 10% Clorox, and eco-enzyme solution. The variables observed in this study were the percentage of contaminant types (fungi and bacteria), the time of contamination, and the percentage of living explants after 28 days of culture. The results showed that eco-enzyme A with a concentration of 100% has the ability as a surface sterilization material in garlic meristem culture, which produces a percentage of living explants of 100%.

Plastic is a commonly used packaging material due to its cheap and wide availability, especially in the food industry. However, plastic is non-biodegradable, leading to a serious problem to the environment from its widespread use. Using starch-based edible films as an alternative to plastic packaging offers a solution to this problem. As opposed to conventional methods of starch extraction for edibles, modern methods such as microwave-assisted extraction (MAE) can improve the functional properties of starchThis research aimed to determine the physicochemical properties of edible films from starch extracted through MAE. The study used a completely randomized design (CRD) with three treatments based on the amount of added starch, namely, Treatment A (3%), Treatment B (4%), and Treatment C (5%). The results from these treatments were compared against control (without MAE). Observations were conducted in triplicate, including parameters such as solubility, thickness, water holding capacity (WHC), oil holding capacity (OHC), and water content. Treatment A (3%) was found to be the best treatment, with a solubility of 76.55%, a thickness of 0.243 mm, a WHC of 38.56%, an OHC of 36.67%, and a water content of 13.79%.
