Abstract

SYNTHESIS L-LACTIC ACID FROM FERMENTATION OF CASSAVA PULP BY USING TEMPEH INOCULUM. This study used cassava waste pulp as a fermentation substrate to produce lactic acid using a tempeh inoculum. Tempeh inoculum is a mixed culture of Rhizopus with Rhizopus oligosporus as the primary fungus. Lactic acid is an organic acid most widely used in the food, pharmaceutical, cosmetic and chemical industries. One of the important uses of lactic acid is as a raw material for producing Polylactic Acid (PLA) biopolymers, namely polymers that can decompose naturally in a relatively fast time. The analysis was performed using the Response Surface Methodology (RSM) method and the Box Behnken Design (BBD) experimental design with substrate concentration parameters, inoculum concentration, and incubation time on lactic acid. The fermentation process is carried out using a flask shaker at a temperature of 30 ºC, pH 6.0, and a rotational speed of 150 rpm. The optimum yield for lactic acid is 6.65 g/L. It was acquired at substrate 20 g/L, inoculum concentration 0.30 % (w/v) at an incubation time of 72 hours.

Abstract

Applying coal-biomass co-firing power generation is the strategy to accelerate the renewable energy share in the energy mix to reach 23% by 2025. Although biomass co-firing trials have been carried out at several Coal-Fired Power Plants (CFPP), the potential for implementing biomass co-firing on a larger scale and for the long-term propose still needs to be identified. This article evaluates emission characteristics and economic aspects of implementing biomass and coal in power plants. The traditional review method is used by identifying journal articles as data sources and further elaborating according to the context of the study. The primary emissions from co-firing biomass with coal contain CO, SO2, NOx, and particulate matter. The coal-biomass co-firing power generation has been widely adopted due to its various positive effects. However, it is still necessary to consider the cost of retrofitting, OM, biomass prices, and incentives in its application.

Abstract

One of the main issues for women in the reproductive age range is leucorrhoea, which causes a woman ongoing distress, and occasionally be the first sign of several of the main gynecological disorders. The widespread use of fluconazole antibiotics has caused Candida sp to become resistant. Alternative non-pharmacological treatments based on natural products are needed, especially P. crocatum which has antioxidant, antifungal, and anti-inflammatory activities. This study analyzed the empirical study of P. crocatum used against leucorrhoea due to C. albicans. The empirical study presented that vaginal discharge was reduced after using P. crocatum formulations. The infection parameter of vaginal pH level, the intensity of pain, and itching were significantly recovered with p values of 0.008, 0.000, and 0.001, respectively, while the reducing C. albicans colonies was 0.001. P. crocatum decoction formulation is effective in reducing vaginal yeast infections in women, close to the results of the positive control, ketoconazole.

Abstract

ABSTRACT Pollution in the water environment is becoming increasingly massive. Rivers are polluted by industrial and household waste, which results in natural systems no longer being able to process pollutant materials that enter water bodies, so technological breakthroughs are needed that can come into direct contact with the surface of the water and be used in rivers and lakes. Phytoremediation is a waste processing method using plants grown in polluted environments. Floating wetland systems (constructed floating wetlands) provide a practical solution for dealing with pollution in the aquatic environment because they are directly in contact with polluted water bodies. Also, selecting plant species for floating wetlands determines the system's success in processing waste. The vetiver plant (Chryzopogon zizanioides (L.) Roberty) is a heavy metal hyperaccumulator plant that can grow well in aquatic and terrestrial environments. Still, it needs to be considered because not all cultivars can grow well in standing water, so they are unsuitable for processing liquid waste. Vetiver plants have several advantages compared to other aquatic plant species for floating wetland applications, such as being non-invasive and having no rhizomes, a root system extending downwards, and a massive root system to be used as a biofilter. Floating wetland systems are not widely used in natural systems or for final waste processing. The research is a literary study of floating wetlands, which has been implemented in several countries. The benefit of this research is to examine the ability of the vetiver plant as a hyperaccumulator plant from several studies that have been carried out so that it can be applied in natural environments. ABSTRAK Pencemaran di lingkungan perairan semakin masif terjadi. Sungai tercemar oleh limbah buangan industri dan rumah tangga, yang mengakibatkan sistem alami tidak mampu lagi mengolah bahan pencemar yang masuk ke dalam badan air sehingga diperlukan terobosan teknologi yang dapat langsung bersentuhan di permukaan air dan dipergunakan di sungai maupun danau. Fitoremediasi merupakan metode pengolahan limbah dengan menggunakan tanaman yang ditumbuhkan pada lingkungan  tercemar. Sistem lahan basah terapung (constructed floating wetlands) memberikan solusi praktis untuk mengatasi pencemaran di lingkungan perairan, karena langsung bersentuhan dengan badan air yang tercemar. Selain itu pemilihan spesies tanaman yang akan digunakan dalam lahan basah terapung menentukan keberhasilan dari sistem untuk menolah limbah. Tanaman vetiver (Chryzopogon zizanioides (L) Roberty) merupakan tanaman hiperakumulator logam berat dapat tumbuh baik dalam lingkungan perairan dan daratan, namun perlu diperhatikan karena tidak semua kultivar mampu tumbuh dengan baik pada genangan air, sehingga tidak cocok untuk pengolahan limbah cair. Tanaman vetiver memiliki beberapa keunggulan dibandingkan dengan spesies tanaman air lainnya untuk penerapan lahan basah terapung, seperti sifatnya yang non-invasif dan tidak memiliki rimpang, memiliki sistem perakaran yang menjulur ke bawah, sistem perakarannya yang masif, sehingga dapat digunakan sebagai biofilter. Sistem Lahan basah terapung belum banyak digunakan, baik dalam sistem alami maupun bertujuan pengolahan limbah akhir. Penelitian ini merupakan studi literatur mengenai lahan basah terapung yang sudah diterapkan di beberapa negara. Manfaat dari penelitian ini untuk menelaah kemampuan tanaman vetiver sebagai tanaman hiperakumulator dari beberapa penelitian yang sudah dilakukan untuk selanjutnya bisa diterapkan di lingkungan alami.
