Abstract

The commitment to provide clean water and proper sanitation is one of the goals of the Sustainable Development Programs (SDGs). The government of each region needs to strive for clean water for the community. Efforts to provide clean water can be realized with the Water Supply System. Water Supply System sustainability indicators need to fulfill three aspects of quality, quantity, and continuity. The aim of this research was to assess the sustainability of the ‘Sugio’ Water Supply System in Lamongan Regency, which served three villages, namely Sugio, Lebakadi, and Sekarbagus. The aspect of water quality, seen from the results of the analysis of the quality of production water, met the quality standards for drinking water. The aspect of water quantity was calculated to meet water needs for the next 20 years. The calculation showed that the daily average debit requirement was 17 L/s and the daily maximum debit was 19 L/s, while the existing debit was 15 L/s. The aspect of water continuity was calculated by the ability to distribute water during an emergency. The calculation showed that the distribution of clean water when there was no source of electrical energy could only be carried out in a maximum of 1 hour, 13 minutes, and 48 seconds. The conclusion obtained was that the sustainability of the ‘Sugio’ Water Supply System from the perspective of water quantity and continuity needed to be improved.

Abstract

Biogas is a gas generated through anaerobic processes that involve the decomposition of organic materials. Various sources of methane can be utilized to produce biogas, including household waste, biodegradable waste, animal waste, or organic materials that can break down under anaerobic conditions. The objective of this study is to investigate how different conditions, such as time, pH levels, stirring duration, and the type and concentration of inoculum, influence biogas production, with the aim of identifying the optimal conditions for the biogas production process. This research focused on examining the factors that impact the biogas production process, which includes several stages like hydrolysis, acetogenesis, acidogenesis, and methanogenesis. The findings from prior experiments showed that the optimal biogas production was achieved using tofu liquid waste, resulting in a volume of 26,700 ml over a 36-day period. This was achieved by maintaining an operating temperature between 35-40°C and employing cow dung as the inoculum, along with a 36-liter digester.

Abstract

Corrosion is metal damage caused by electrochemical reactions with its environment. This environment can be water, air, gas, acid solution, salt solution, and others. Metals are highly active in producing an oxide layer on the metal surface under the influence of an aerobic environment. Metal corrosion is a process where the action of the surrounding media damages metal materials by the introduction of corrosion ions. This study aims to determine the best conditions for phosphate in controlling the rate of corrosion and Knowing the inhibition of phosphate on controlling the rate of corrosion. The materials used were stainless steel 201, stainless steel 304, and phosphate as an inhibitor. Meanwhile the solution NaCl 3.5% as a corrosive media environment and distilled water. Based on this research, the best phosphate concentration in reducing the corrosion rate of stainless steel 201 and 304 is 100 ppm with a reduction in the corrosion rate of stainless steel 201 of 0.022312 mpy with an inhibition percentage of 89.68%, and a reduction in the corrosion rate of stainless steel 304 by 0.045694 mpy with the percentage of inhibition is 94.027%. The corrosion rate of 304 stainless steel is lower than that of 201 stainless steel caused by differences in the Cr element composition of each metal. Stainless steel 304 contains 18.24% Cr while stainless steel 201 contains 13.00% Cr. The lower the Cr content in stainless steel, the stainless steel will be more susceptible to corrosion.

Abstract

Cherry (Muntingia calabura L.) leaves have been acknowledged for their potential as a rich source of various components including alkaloid, flavonoid, tannin, saponin, triterpenes, and polyphenol. Alkaloids play diverse roles in medical science. Isolated alkaloids from plants are already widely used in traditional medicine.  Obtaining alkaloids from the leaves required an extraction process using organic solvent. This study aimed to evaluate the mass transfer coefficient for the extraction of alkaloids from cherry leaves using ethanol as a solvent. Dried cherry leaves were contacted with 96% ethanol at different temperatures and contact times. The extraction temperature ranged from 60, 65, 70, 75, and 80oC while the contact time varied from 30, 60, 90, 120, and 150 minutes. The extraction process was conducted with a mixing speed of 440 rpm. With the increasing contact time and extraction temperature, there was a corresponding increase in alkaloid concentrations. The optimal extraction conditions were achieved at 75oC with an extraction time of 150 minutes, resulting in an alkaloid content of 0.6486 gr/ml. The mass transfer coefficient under these extraction process conditions was 1.7923 hour-1. These data are crucial for the design and scale-up of extractors to achieve optimal results.

Abstract

Bioactive compounds derived from plants are gaining attention worldwide because they have beneficial effects on humans. Rhizophora mucronata is a species of mangrove plant that has slightly dark leaves and glossy green on the top of the leaves and pale green on the bottom and acts as a natural antioxidant which has traditionally been used as a food ingredient and traditional medicine. Therefore, this article was written to review the bioactive compounds in Rhizophora mucronata leaves, antioxidant levels and the benefits of antioxidants in food and health products. This article summarizes relevant literature regarding R. mucronata which was tested using Phytochemical screening, FTIR and DPPH (1,1-diphenyl-2-picrylhydrazyl) methods. Phytochemical analysis revealed the presence of alkaloids, flavonoids, steroids, phenolics, tannins and saponins. Based on the FTIR test, R. mucronata leaf extract showed the presence of –OH, C-H (aromatic), C=C (aromatic), and C-O groups. The antioxidant capacity expressed in IC50 (mg/mL) shows that R. mucronata has the potential to be used as a source of natural antioxidants. Antioxidants can play a role in improving the sensory quality of a food product and as a natural bactericidal so that it can be used to maintain aquatic biota and food preservatives. In addition, antioxidants contained in mangroves can prevent aging, wrinkles, cancer, obesity, and diabetes mellitus.

Abstract

This research aims to evaluate the influence of Green Product Milo packaging on consumer buying interest. A quantitative descriptive research method was used by applying path analysis through a questionnaire distributed to 120 Milo consumer respondents. The research results show that Green Product adoption has a positive effect on repurchase intention. The implication is that companies need to maintain Green Products by continuing to innovate quality and environmentally friendly products and increasing promotions through potential media such as Instagram. Statistical analysis shows that there is a significant relationship between the level of product completeness and consumer attractiveness (p < 0.05). Although the correlation between the level of environmentally friendly products and purchase intention is relatively weak (correlation 0.411), the regression model shows a positive influence. From the results of ANOVA calculations, this regression can be used to predict purchasing interest in environmentally friendly products. It can be concluded that Green Products have a significant influence on consumer buying interest by contributing 16.9% to the variability in buying interest. This research provides an important contribution to companies in making strategic decisions related to product development and marketing.
