Abstract

This study investigates the potential of KOH-activated dragon fruit peels as an adsorbent for the removal of Cd2+ ions from solution. The adsorption performance of the activated dragon fruit peels was evaluated through batch adsorption experiments, where various parameters including adsorbent dosage, initial Cd2+ concentration, contact time, and solution pH were examined. The optimum condition for the adsorption process was pH 5, stirring time 120 min, adsorbent dosage of 20 mg (in 25 mL solution).  The findings highlight the potential of utilizing agricultural waste materials, such as dragon fruit peel, as an effective and sustainable adsorbent for the removal of heavy metal ions from water sources, contributing to environmental remediation efforts.

Abstract

Hummock is a typical morphology that is not found anywhere except in the active mountains. This uniqueness is due to the isolated hill shape with plain morphology formed in the geological setting. The existence of Gumuks dissiminated in Jember has been mined, causing their numbers to decrease drastically. Hummock in Jember district has a unique hill-shaped landscape with a height of over 2 meters. Hummocks in Jember are arranged from Raung Mount to the southwest to Jember Regency. There are several types (three) types of dunes that differ from the type of rock contained, namely rock dunes, coral dunes and sand dunes. At this moment, the existence of Hummock has been partially used for building material needs. The problem faced now is that the potential for piles other than as a building material requirement has not yet been researched. Therefore, effective management is needed through the identification of potential dunes through green mining research so that environmental problems are minimized when dune exploration is carried out. The purpose of this study was to find a green mining-based dune exploration technology, so that the treatment of each dune can be carried out appropriately. The stages of the research were carried out by observing the images. After the observations are made, field data is needed to validate and verify the pattern of dune. The research used remote sensing with guided techniques based on data in the field and geological maps. Based on remote sensing results it was found that there were 4 Classes in Land Use Change after Mining Operation carried out by people around the mine site.

Abstract

The existence of clean water on this earth is very necessary to support the lives of humans and other living creatures. Sustainable management of clean water sources is necessary to ensure that the quality meets certain requirements or quality standards, which often becomes a problem, especially regarding measurement methods that require a long time and are quite expensive. This condition demands innovation in water quality measurement methods that are fast, accurate and cheap. The aim of this research is to examine the accuracy of an Android-based water quality measuring tool using a smartphone, especially the parameters of temperature, turbidity, Total Dissolved Solid (TDS), pH and conductivity simultaneously. The method used in this research is that prepared water samples are measured using an Android-based multi-parameter measuring tool developed in this research. The results of repeated testing at least ten times for each parameter are compared with the measurement results of calibrated measuring instruments available on the market, then statistical tests are carried out to see the performance of the measuring instruments that have been developed. The results of this research show that for all test parameters using this measuring instrument the values ​​are very close to the measurement results using the manufacturer's measuring instruments that are commonly used. It is hoped that the results of this innovation will be an alternative choice for measuring several water quality parameters accurately, quickly, easily and cheaply based on Android and be able to overcome environmental problems in the future.

Abstract

Honey is a food product produced by bees. Honey is obtained by separating the liquid honey from the beehive. At the Gubuk Lanceng Magelang farm, honey is still squeezed manually, which is squeezed by hand, so the honey obtained is not optimal and the propolis produced is irregular. The purpose of this study was to design a honey squeezer that could squeeze the hornet's nest while printing propolis into pieces by using a screw mechanism for the pressing process. The honey squeezer is made based on several criteria such as corrosion resistance, easy operation, easy cleaning, capable of printing propolis, and affordable prices for UMKM. The design includes the design and manufacture of components which include the frame, filter tube, container, turning lever, and pressure plate. The capacity of this tool itself is 4 kg. In testing the tool using a honeycomb weighing 300 grams and testing for 3 trials, the test results show that the honey squeezer can work better than hand squeezing. The test results show the efficiency of the honey squeezer is 45% compared to the hand squeeze which is only 29.5%. The resulting form of propolis also has the same shape and size as each other.

Abstract

In Indonesia, online food delivery (OFD) services consist of 2 (two) types, namely OFD by Platform and OFD by restaurant apps.  Data shows that users of OFD by restaurant apps are ahead year-on-year compared to OFD by Platform users. This proves that although these 2 (two) types of applications are in the same industry and provide the same service, namely online food delivery (OFD), they still have differences that are influenced by certain factors. The study aims to analyze differences in Purchase Intention on Platform-Based Online food delivery Applications (Go food, Grab food and Shopee food) and Restaurant (KFCKU, Pizza Hut Indonesia and McDelivery) by involving Online Customer Review variables, sales promotion, and Website Quality as well as the intervening variable e-trust. This research was conducted with 100 respondents. The sample collection technique in this study used purposive sampling technique. This study uses quantitative methods and path analysis tests. The results in this study explain that there is a direct influence between Online Customer Review (X1) and Website Quality (X3) on E-Trust (Z) in the OFD by Platform application and the OFD by restaurant application. In OFD by Platform, there is no direct influence between Sales Promotion (X2) and Website Quality (X3) on Purchase Intention (Y). In OFD by restaurant, there is no direct influence between Online Customer Review (X1) and Sales Promotion (X2) on Purchase Intention (Y). In addition, there is an indirect influence between Online Customer Review (X1) and Website Quality (X3) on Purchase Intention (Y) through E-Trust (Z).
