Abstract

The level of competition in the tape industry is often discussed nowadays, because of the promising business opportunities for tape as a souvenir product typical of the city of Bondowoso. Apart from that, the decline in the availability of cassava raw materials since the Covid-19 pandemic has encouraged tape producers to look for raw materials of the best quality, which has resulted in a mismatch between the acquisition of raw materials and the level of demand. Raja tape is one of the MSMEs operating in the food sector located in Bondowoso, East Java. Raja Tape often experiences shortages of cassava raw materials. Often yellow cassava supplies are taken to middlemen even though the price difference is different, which results in an imbalance between demand and supply in the following period. After conducting observations andinterviews with the owner of Raja Tape, the researchers identified supply chain management problems, the first of which was due to the lack of yellow cassava raw materials. Apart from that, the supply chain flow of tape products, starting from raw materials, land area requirements and seeds from raw material components needed to fulfill production. The results of this research obtained the needs of each component in the tape supply chain, namely land area and cassava, banana and bamboo tree seeds. This was done todetermine optimal needs for tape supplies at Raja Tape.

Abstract

Currently, the most waste comes from households at 38.4%. Efforts to deal with these problems are made by making compost with the addition of bioactivators to speed up the composting process. The purpose of this study was to compare the results of compost with the addition of variations of coconut husk MOL, used rice MOL, combinations MOL and get the best results in accordance with SNI 19-7030-2004. This study used raw materials from household organic waste and MOL variations, namely coconut husk, used rice, and a mixture of both. In addition, it also uses variations in the dose of MOL, namely 5ml and 10ml. This study showed that the addition of MOL variations was more effective than control variations. The results showed that MOL coconut husk and used rice have a high bacterial content so that they can be used as bioactivators, compost results based on physical parameters have met SNI, namely having a blackish color, earth-like texture, and smelling of soil. Compost with the addition of a bioactivator (MOL) mixture of coconut husk and used rice dose of 10ml has a C/N ratio value of 15.14 and a high reduction rate of 63.80%. This variation is more effective in degrading organic waste compared to other variations. The use of natural bioactivator materials is environmentally friendly, economical and also more effective in degrading household organic waste.

Abstract

Environmental sanitation problems occur not only in households but also in educational institutions, including Islamic boarding schools. The aim of the research was to determine the environmental sanitation conditions at Al-Urwatul Wutsqo Jombang Islamic Boarding School and the influence of students' behaviour on the environmental sanitation conditions there. Observation and interview methods were used to determine the environmental sanitation conditions at Al-Urwatul Wutsqo Jombang Islamic Boarding School. Meanwhile, research on students' behavioural variables, namely knowledge, attitudes and actions through the method of filling out questionnaires. Based on the research results, it shows that there are still several indicators of environmental sanitation conditions that do not meet the requirements of legalregulations, one of which is the condition of providing clean water that does not meet the requirements as a raw material for drinking water because it has a rather high TDS level, namely 628 mg/L. Then, the resultsof the data analysis test showed that students' knowledge did not have a significant positive relationship with environmental sanitation conditions, but students' attitudes and behaviours had a significant positive relationship with environmental sanitation conditions.

Abstract

Solar panels are an increasingly popular technology for generating electricity from sunlight. However, the performance of solar modules can be affected by various environmental factors, including heat transfer.High heat transfer can lead to an increase in the temperature of the solar panel and ultimately reduce the output voltage and energy conversion efficiency. Heat from the sun absorbed by the solar module can increase the temperature of the module and reduce the output voltage. Efforts must be made to reduce thetemperature of the solar panel so that the performance of the solar panel remains optimal. This manuscriptinvestigates the effect of heat transfer on the output voltage of solar modules. Various studies have beencarried out to evaluate the effect of heat transfer on solar module performance, taking into account factors such as the thermal conductivity of the module material, cooling design and environmental conditions. Theinstallation of a heat sink is one of the efforts made to cool the solar module. The heat sink can dissipate an average of 8710.16 joules/second, reducing the average temperature of the solar module by 37.57°C and increasing the average output voltage of the solar module to 19.4 volts. The results of this research showthat the use of heatsink material is better for reducing the temperature of solar modules. The use of a heat sink with a large surface area further accelerates the heat transfer process in the solar module

Abstract

One type of liquid waste that is commonly encountered is waste from the tofu production process. Tofu production waste contains organic matter and chemical compounds that can pollute the environment if not properly managed. The increase in the amount of liquid waste generated is due to the growing human population and increasing industrial activities. Eco enzyme, which is produced by simple fermentation of fresh vegetable or fruit organic waste, molasses and water in a ratio of 1:3:10, has been shown to be beneficial in reducing pollution levels. Therefore, the objective of this study was to evaluate the potential of Eco enzyme as a supporting solution in reducing TSS and COD content in wastewater from tofu industry through anaerobic process. In this study, variation of anaerobic process was used by mixing Eco enzyme solution at 5%, 10% and 15% concentration. Anaerobic process was carried out with retention time of 5, 10 and 15 days. The results showed that fruit Eco-enzyme was more effective than vegetable Eco-enzyme. Anaerobic process with 5% concentration was able to reduce the pollutant parameters with the highest efficiency, which was 6.17% for TSS parameters and 89.17% for COD parameters on the 15th day of detention.

Abstract

Heavy metals, including iron (Fe), are commonly found in industrial wastes and end up contaminating water sources. Although their presence is essential in various industrial applications, high concentrations of heavy metals can lead to toxicity and health problems. Therefore, adsorption methods have been used as an approach to reduce the concentration of heavy metals in water. Maggot shells have been identified as potential biosorbents because they contain chitin compounds that can interact with heavy metals. The aim of this study was to evaluate the influence of stirring time on the adsorption process of maggot shells on the heavy metal Fe. The adsorption method used was a batch system with a stirring speed of 150 rpm. The results showed that the increase in adsorption efficiency was consistent with the increase in stirring time. Stirring time plays a crucial role in enhancing the interaction between the biosorbent and Fe metal ions, resulting in increased removal efficiency. However, the effect of stirring time is limited after the saturation point is reached.

Abstract

Urea is a nitrogenous compound produced by the reaction of ammonia and carbon dioxide at certain temperatures and pressures. Urea is commonly used in the fertiliser industry and liquid waste may be generated during production. Waste from urea fertiliser plants contains urea and ammonium in concentrations of 1,500 to 10,000 ppm and 400 to 3,000 ppm respectively. Electrolysis technology has been developed to treat waste water containing ammonia. Electrolysis is a process in which water molecules are split into hydrogen and oxygen gases by passing an electric current through electrodes containing an electrolyte solution (water and catalyst). This research aims to determine the effectiveness of reducing ammonia (NH3-N) and pH levels using electrolysis methods with copper (Cu) and carbon (C) electrodes, carried out with different numbers of plates: 2, 4, 6 and 8 plates. The variations in electrolysis time (td) used are 0 minutes, 30 minutes, 60 minutes, 90 minutes and 120 minutes.
