Abstract

The purpose of this research is to utilize weed grass and kirinyuh leaves as raw materials for making biopesticides and test their effectiveness in controlling leafhopper pests in rice plants. In addition, it is also an innovation in making natural pesticides to reduce the use of chemical pesticides in Indonesia. The research method used is descriptive with a quantitative approach. The type of research used is a comparative method which compares one or more variables in two or more different samples, or at different times. The focus of this description is the effectiveness of biopesticides from teki grass weeds and kirinyuh leaves. Data collection was carried out by experiments and literature studies. Experiments were conducted to determine the effectiveness of the product and literature studies were conducted to analyze the effectiveness of biopesticides from weed grass and kirinyuh leaves. The indicator of product effectiveness is that leafhopper pests shrivel and change color. Based on the test results, it was found that biopesticides from weed grass and kirinyuh leaves had a pest mortality value of 88.24%, efficacy of 87.88%, inhibition and development of pests of 88%, and had a pH level of 6. Suggestions for further research are to use other plant materials that are even more effective in controlling leafhoppers with minimum toxic effects.

Abstract

The skin, the body's largest organ, plays a key role in protection, temperature regulation, sensation, sweat excretion, and vitamin D synthesis. It also serves as a barrier against external agents and prevents fluid loss. However, the skin is highly susceptible to damage, including burns caused by tissue damage due to heat. The WHO says burns cause about 180,000 deaths a year. But first and second-degree burns can be treated at home.This study developed an algae-based burn bandage with ginger and cucumber extracts in hydrogel to protect the wound from bacteria and facilitate skin regeneration. The study used a qualitative descriptive method to test the effectiveness of ginger and cucumber extracts in a hydrogel for wound treatment and the convenience of using biofilm.The tests included antimicrobial, skin irritation, solubility, biodegradable, elasticity, and organoleptic tests.The study found that the active components in the product can eradicate bacterial microbes, ensuring its safety, and dissolve in water within three days. The product's properties include elasticity, easy decomposition, a noticeable ginger aroma, a soft and chewy texture, and a slightly dark, clear color.
Optimalisasi Fermentasi Bioetanol dari Kulit Durian Lokal (Durio zibethinus) dengan Penambahan Vitamin B Kompleks Sebagai Bahan Bakar Rumah Tangga Rafi Rijal Mufaiq; M. Nuril Yazdan Al-Firdhaus; Giesty Trienita; Agus Widayoko

Abstract

Indonesia still faces a high dependence on LPG, making the development of more sustainable alternative energy sources necessary. On the other hand, durian peel waste is abundant but has not been optimally utilized as a raw material for bioethanol. The low efficiency of lignocellulosic biomass fermentation remains a major obstacle; therefore, the aim of this study is to determine the effectiveness of adding B-complex vitamins to bioethanol production by examining the resulting ethanol content. The type of research conducted is descriptive research with a quantitative data approach. Data were collected through literature studies, observations, and experiments. The research procedures included delignification, hydrolysis, fermentation for 6 and 7 days, and distillation. To determine product effectiveness, analyses of ethanol content, density, and flash point were carried out. The results show that the addition of B-complex vitamins significantly increases the quality of bioethanol, with ethanol levels reaching 99.5% on day 6 and 97.7% on day 7, higher than without vitamin addition. The density ranged from 0.7992 to 0.8315 g/ml, which is close to the SNI 7390:2012 standard, while the flash point of 11–12°C indicates good ethanol purity. Thus, durian peel waste has potential as a second-generation bioethanol feedstock, and B-complex vitamins have been proven to improve fermentation efficiency and the quality of the resulting ethanol based on ethanol content analysis.
Optimalisasi Bioherbisida Berbasis Limbah Kulit Jeruk Nipis (Citrus aurantifolia.) dengan Penambahan Effective Microorganisms (EM) sebagai Pengendalian Gulma pada Sektor Pertanian Padi Muhammad Fardan Islam; Evan Fausta Subagya; Giesty Trienita; Agus Widayoko

Abstract

This study aims to optimize bioherbicides based on lime peel waste (Citrus aurantifolia) supplemented with Effective Microorganisms (EM4) as an environmentally friendly alternative to synthetic herbicides in rice fields. This study utilizes natural phytotoxic compounds such as flavonoids, limonene, and tannins, which are enhanced through microbial fermentation. This study is descriptive with a qualitative comparative approach. The methods used include Soxhlet extraction with 96% ethanol, fermentation with EM4 concentrations of 0%, 3%, 5%, and 10%, and seven days of observation of organoleptic properties, soil pH, and weed toxicity. Data analysis compared changes in solution and weed response between treatments. Increased EM4 concentration resulted in a stronger odor, darker solution, and higher herbicide effectiveness; the 5% and 10% treatments caused total drying and collapse of weeds within 5–7 days, while 0% and 3% only caused mild chlorosis. Soil pH remained stable at 7, indicating no negative effects on soil fertility. Therefore, lime peel bioherbicide shows strong potential as an effective, inexpensive, and sustainable weed control option.
