Abstract

Digitalis purpurea (Schrophulariaceae) is used by the local Indonesian community as an ornamental plant, even though this plant has high toxicity and has the potential to treat heart problems. This study aims to explain the botany, bioactivity and toxicity of D. purpurea based on literature studies. Literature was obtained online, especially Google scholar using the keywords Digitalis purpurea, bioactivity D. purpurea, and glycoside heart. In Europe, D. purpurea is very popular to treat congestive heart failure and has been used since 200 years ago, but it is very toxic to humans. Digitalis poisoning causes anorexia, nausea, vomiting, and diarrhea, yellow or jaundice vision, appearance of blurred lines, decreased heart rate, and weight loss. D. purpurea's bioactivity includes overcoming heart failure, antioxidants, anti-cancer/tumor. Cardiac glycosides present in D. purpurea include cardenolides, digitoxin, gitoxin, purpureaside A, purpureaside B, acteoside and purpureaside C, which are related to their bioactivity. The toxicity and inotropic effects of cardiac glycosides result directly from inhibition of membrane-bound Na+K+_ATPase, an enzyme involved in the transport of Na+K+ across cell membranes. The use of D. purpurea needs strict control so that side effects can be minimized.

Abstract

Plastic is difficult to decompose in nature because it is a synthetic polymer made by humans and is made from petroleum. The problem that arises from the uncontrolled use of plastic is the accumulation of plastic waste in the environment which is not handled properly and becomes a source of environmental pollution. Plastic waste creates various kinds of environmental problems that disturb the balance of ecosystems and have an impact on the life of organisms in the environment. To overcome this problem, it is necessary to carry out related research as an effective solution for dealing with plastic waste. Biodegradation is one of the right methods for dealing with plastic waste now and in the future. However, there is limited review of the bio-decomposition of plastics, the microbial species present, the effectiveness of degradation, and the mechanisms involved. Based on this, this research focuses on a brief review of plastic biodegradation such as the factors that affect biodegradation, the species of microorganisms that play a role in the degradation of macro and micro-plastics, as well as the mechanism of plastic degradation through enzymes from the viewpoint of microorganisms. Various species of microorganisms such as bacteria, algae and fungi have the ability to decompose plastics but they cannot mineralize plastics completely. Meanwhile, research on the enzymes involved in plastic degradation is still limited, especially in the case of algae. This review can be a reference for researchers to find effective strategies to address the problem of plastic waste worldwide.

Abstract

Household organic waste can be used as material for organic fertilizer for supporting urban farming activities. Organic fertilizer is beneficial as an effort to reduce waste’s negative impact to environment, and to minimize the use of chemical fertilizers. This research aimed to study the macro nutrient content of fruit peel based-liquid organic fertilizer (LOF) and its effect on the growth of Pakcoy (Brassica chinensis L.). Several fruit peels from household organic waste such as banana, mango, orange, dragon fruit, and papaya peels were used as material for LOF preparation. The research was conducted with completely randomized design (CRD) method with 5 treatments and 5 replications, namely the K- (without fertilizer, only water), K+ (0.2 mL commercial LOF), P1 (0.1 mL fruit peel based-LOF), P2 (0.2 mL fruit peel based-LOF) and P3 (0.4 mL fruit peel based- LOF) for 56 days of observation. The obtained data were analyzed using one-way ANOVA. Results showed that macro nutrients of fruit peel based LOF did not yet meet the quality standards set by the Ministry of Agriculture, and the dose of 0,4 ml fruit peels based-LOF showed the best effect to support the growth of the Pakcoy plant in all Pakcoy growth parameters. Keywords: Fruit Peels, eco enzyme, macro-nutrients, pakcoy
