Abstract
Wetland in South Kalimantan, especially swamp land, covers 6.07% of the land area. Wetland base products need to be accommodated in a start-up by providing a business design model accommodating many users. The research aimed at designing a business model accompanied by monetization to become a reliable start-up specifically for wetland commodities applying the concept of design thinking. The methodology began with conducting a needs analysis, determining an issue strategy, creating a demand design using the Analytical Network Process, establishing a Hierarchial Task Analysis for idea development and product design, conducting brainstorming, followed by further analysis until creating a Business Model applying five design thinking concepts, namely empathize, define, ideate, prototype and test. The application built based on the business model was named Hiyung Wonderful Wetland, Lambung Mangkurat University (HW2 ULM). Analysis of user needs included Admins, Innovators, Partners who were individual consumers/wholesalers, material providers and for monetization purposes. Entity Relationship Diagram (ERD) started from identifying to determine what entities used in the diagram, then determining the entities having relationships, followed by adding attributes and determining key attributes for each entity. After carrying out the empathize, define, ideate stages towards users, a prototype was produced with a wireframe design starting from the start page, registration, main page, consultation page, chat page schedule, pay page to forum page. The application of the Test concept was still being verified towards target validation. The visualization (UI) and Application part involves the user’s feelings when operating a digital product (UX) likewise with the back end having high security.

Published: June 2024

Abstract
Lighting plays a crucial role in achieving the targeted performance in the cigarette paper inspection department. The inspection process, which involves assessing paper quality for evenness, cleanliness, and symmetry, falls short of the goal of 77 reams per worker per shift. Illuminance levels currently average 55 lux, significantly below the recommended standard of 200 lux. This insufficient illumination leads to a failure to meet the required 178,200 lumens, resulting in the unmet cigarette paper production target. To address this issue, two alternatives are proposed. The first involves replacing the existing lamps with a different type and reorganizing the lamp layout. This layout adheres to the principle of uniformity and spacing criteria, resulting in the placement of seven lamps with a 4.08-meter gap between each. This arrangement ensures that lighting is concentrated directly above the packaging table and evenly distributed throughout the room. The second alternative is to augment the existing lighting by adding lamps to the packaging tables, each with a luminous flux of 200 lumens. These lamps can be conveniently attached to the table leaves and adjusted to suit the workers’ specific needs. These proposed changes aim to improve lighting conditions and subsequently enhance productivity in the cigarette paper inspection department.

Abstract
The transformation of rice farmers from farmer groups to a corporate business entity necessitates their ability to meet rice productivity targets and implement a sustainable business model. This study aimed to analyze the current conditions of rice farmer corporations, including their rice production performance, added value, and business models. Initially, the performance of these corporations was assessed by comparing it to rice productivity targets. Subsequently, the Hayami method was used to analyze the added value generated by the farmers. Furthermore, the existing business model of the rice farmer corporation was described, and the canvas business model method was employed to identify elements that impact the sustainability of the rice business. The research was conducted in the rice agro-industry center locations in Subang Regency. Rice productivity still lower than target, it is crucial to prioritize post-harvest handling as it plays a vital role in minimizing crop yield losses. The findings of the value-added analysis conducted within the company obtained is good and indicate that both processing procedures have the potential to create additional value. In order for this business activity to function effectively, certain resources are required. To ensure the stability of this business, partnerships are essential, benefiting both the corporation and its partners. Moreover, the development of a business model is expected to enhance the role of rice farmer corporations in promoting the growth of national rice production.

Published: June 2024

Abstract
Sales forecasting must be done to meet consumer demand for cheese products. PT XYZ is one of the companies that distributes cheese products and makes forecasts by averaging three months of sales. The average value of the resulting deviations is close to the forecast limit, which is said to be quite good, around 31% -39%. In this project sales forecasting of three cheese products was carried out using the Exponential Smoothing method: Pegel Classification and Autoregressive Integrated Moving Average (ARIMA). Both methods are used to compare the value of accuracy between the two methods with the company. One of the two methods with the highest accuracy value will be recommended for forecasting sales to companies. The results of the project show that the two methods on average have a better accuracy value than companies where forecasting using the ARIMA method has a better accuracy value than the Pegel Classification so the ARIMA method is recommended in sales forecasting. The accuracy value of the three products using the ARIMA method is about 6-10% higher than the Pegel Classification.

Abstract
Research focusing on microalgal as an alternative source of protein and fat in ruminant feed shows a growing trend. Microalgae are rich in carbohydrates, proteins, fats, amino acids, vitamins, minerals, and carotene. Ruminants can digest the cell walls of microalgae, positively affecting their health, growth, metabolism, reproduction, production, and product quality. This paper introduces the latest review of microalgae on ruminant feed and its effect on performance, production, and quality of meat and milk. The results showed that using microalgae does not increase milk production in dairy cows but substitutes protein from corn and soybean meal. Microalgae improves the quality of meat and milk through the changes in fatty acid profiles associated with omega 3, especially DHA and PUFA, which benefit human health. However, some microalgae species reduce palatability, feed consumption, and weight gain. Feeding microalgae to livestock as a supplement or substitute protein for soybean meal protein or other ingredients requires considering the limiting factors of lipid concentration and the economic value of microalgae species.

Abstract
Leather industry is one of essential industry in Indonesia, However, the production of leather products produce load of pollutions. This study aims to analyze and focuses on the addition of alkaline protease in the dehairing process and chestnut as a vegetable tanning agent in goat skin in an attempt to minimize the usage of chemicals that were detrimental to the environment despite generating good leather quality. In this study, 10 pieces of raw goat skin were used and processed from soaking to basic dyeing process. The analysis of data used One-Way ANOVA (Analysis of Variance) to discover the differences between treatments. Treatments were divided into 4 categories that were : P0: a control treatment (0% alkaline protease+ 3% H2S and 6% limes + 25% mimosa), P1: 1% alkaline protease with 2% H2S and 5% limes + 25% chestnut, P2: 1% alkaline protease with 1% H2S and 4% limes + 30% chestnut, P3: 2% alkaline protease with 1% H2S and 4% limes + 25% chestnut and P4: 2% alkaline protease with 1% H2S and 4% limes + 30% chestnut. The examination tested was the morphological observation by Scanning Electron Microscope (SEM), tensile strength, elongation, tear strength, and shrinkage temperature. The SEM study indicates the addition of alkaline protease softens the goat skin, nevertheless, there is a non-significant difference between treatments (P>0.05) on tensile strength and elongation strength, however, there is a significant difference (P<0.05) on tear strength and shrinkage temperature. The conclusion is treatment P4 (2% alkaline protease with 1% H2S and 4% limes + 30% chestnut) generates the best result.
The importance of print orientation in numerical modelling of 3D printed structures under impact loading
Authors: Fisher Tom , Kazancı Zafer , Almeida Jr José Humberto S 
Published: June 2024

Abstract
Anisotropy is commonly observed in 3D-printed polymer and composite parts, particularly when manufactured by fused filament fabrication (FFF). This anisotropy can lead to difficulty obtaining accurate material properties during mechanical characterisation. This study establishes a connection between the print parameters used in specimen characterisation and their influence on the accuracy of numerical models for 3D-printed cellular structures under impact. Material properties from only one of the characterisation variants studied, with a parallel infill, accurately represented the force response and physical damage of the experimental samples. In contrast, the default characterisation specimen with a ±45° infill underpredicted the peak force and overpredicted the impact duration, potentially leading to underestimating impact severity. This discrepancy could result in greater damage to a person or structure being protected. It is recommended that the parallel infill pattern be used when characterising materials for use in FFF cellular structures under impact loading to ensure more reliable simulations and improved design of impact-resistant structures.

Published: June 2024

Abstract
Hawassa characterizes a typical developing city in Ethiopia, owning to rapid urban growth and demographic trends. The combined effect of climate change and urban expansion is increasing the challenge to the environment and the services it provides. Relating changing environments with urban water management (UWM) is required to build resilience in the urban environment. This research analyzed local climate change and urban growth and linked it to UWM. The historical period 1990–2021 of daily rainfall, temperature variables, four satellite imageries, and DEM were analyzed. Changes in rainfall (annual and daily maximum) and temperature (maximum and minimum) trends are detected and projected to 2051 using a statistical-based model. With geospatial techniques sub-watersheds are delineated, and the urban cover change is quantified. The trend detection result implies an upward trend of annual and daily maximum rainfalls however a significance is insufficient (p > 0.05) to associate it with climate change during the study period. Maximum and minimum temperatures change indicate a positive and significant trend. The forecasting result suggests an increment of both temperatures (0.5 °C–1.5 °C) to the projected period compared to historical scenario. The land cover analysis results show the built-up area changed from 11.6 km2 (7.2%) to 42.5 km2 (26.5%) during the historical period, where the rate varies spatially. The surface runoff increased by 30.7% in the urban watersheds. With a growth rate of 8.9% built-up, the urban area will cover 73.6 km2 (45.9%) for the predicted period. The research finding justifies the potential to reorganize the relationship between the spatial effect of climate change and urban growth on UWM. Considering distinct characteristics of urban watershed, exposure to flooding risk, access to water demand and resilient to climate change have spatial variation. Thus, a local-specific planning approach will support effective UWM and climate adaptation for sustainable city development.
Researchers must address regulatory regimes to scale up adoption of urine diversion systems in the U.S.
Authors: Merck Ashton , Grieger Khara , Crane Lucas , Boyer Treavor 
Published: June 2024

AbstractUrine diversion (UD) is a system-of-systems that involves source separation of waste to maximize recovery of valuable nutrients, including phosphorus. Recent research shows how UD systems offer valuable ecological benefits and can aid in water conservation efforts, and public perception studies suggest that UD systems are generally viewed positively by end-users and the general public. Nevertheless, adoption and implementation of this promising sustainability solution remains limited in many countries, including the United States (U.S.). In this perspective, we argue that in order to scale up adoption in the U.S., UD researchers and innovators must do more to address regulatory barriers. We draw on insights from political science research on ‘regulatory regimes’ to introduce the array of regulations that apply to UD systems, with a focus on commercial and institutional buildings. We examine regulatory regimes all along the UD system-of-systems, beginning at the point of collection and ending at the point of beneficial reuse. We then propose next steps to address current regulatory challenges that impact adoption, with an emphasis on the importance of stakeholder coordination. Throughout, we argue that law and regulation plays a critical role in shaping adoption of UD technologies because: (1) different regulatory regimes will be important at different points in the system-of-systems, (2) there may be multiple regulatory regimes that apply to a single subsystem, and (3) it is important to consider that legal and regulatory definitions of a technology may not match scientific understanding.
