Abstract

The bamboo ladder is a traditional construction equipment that still survives on the market and is in demand, especially in rural communities such as Kedalingan village. However, bamboo stairs still do not consider the standard of stairs design. In addition, there are concerns that users of the ladder may experience injury due to falls because the ladder cannot withstand the load (unbalanced). This study aims to obtain the maximum load that can be held by bamboo ladders and the angle of the position of the safe ladder by considering the Indonesian people's anthropometric weight. Calculation results based on the principle of equilibrium show that with a maximum user weight of 89.25 kg, the ladder must be positioned with a minimum slope of 53,26o but less than 65.43o. In addition, a static loading simulation was carried out using SolidWorks 2019 on a bamboo ladder frame structure that was made referring to SNI 19 - 1956 – 1990. Simulation results show that the design of a bamboo ladder can withstand a maximum body weight of 89.25 kg with the maximum load value of bamboo holding is 98.93 kg.

Abstract

Bibliometric analysis is a methodology that can be used to investigate patterns in publications based on data cited from academic literature. This research is conducted to comprehensively analyze selected topics. This paper presents the evolution and structure of the chosen research topic. The goal is to obtain an overview of information about the foodborne pathogen research that has been conducted, with the hope that this information can provide insights and guidance for further research related to foodborne pathogens. This paper is also expected to open up new opportunities for identifying gaps in the analysis of potential innovations in foodborne pathogen research, which can serve as a reference for future studies.   Bibliometric literature analysis is centred around the main components using Bibliometrics and VOSviewer. This analysis is based on articles published in Scopus journals from 2013 to 2023. Data extracted from the Scopus web shows an increasing trend year by year, with the United States having the highest number of articles, totalling 3,109, and 22 countries with the lowest number of articles. As for the categories based on the source of information, they can be grouped into journals, books, book series, conference proceedings, and undefined sources. The visualization network shows five different colours, with each colour representing the number of clades generated from the analysis. Based on this, it can be concluded that a significant amount of research related to foodborne pathogens has been conducted, with many studies focusing on pathogens in animals, food microbiology, food control, antibiotic resistance, and pathogens in non-human subjects.

Abstract

Developing an agro-eco-industrial park based on the tofu industry must consider the balance of each agro-industry's production capacity. This research aims to (1) develop an optimization model for material flow between industries and (2) explain the material flow and provide waste utilization recommendations for other industries to create a closed loop. The industries involved in this agro-eco-industrial park consist of the tofu industry, fertilizer producers, tempeh gembus producers, cattle farms, biodigesters, paddy farmers, soybean producers, and nata de soya producers. The model was created using a goal programming approach. Traditional tofu processing generally generates a variety of waste with high nutritional value, but it is detrimental to the environment if disposed of directly. The flow of materials among the related industries is based on the tofu industrial cluster, which consists of 30 industries in Grobogan, Central Java, Indonesia. The expected output comprises eight decision variables representing the production amount of industries. Data analysis reveals that the model outperforms the current conditions, with the waste recycling rate increasing from 14 % to 97 %. This model converts waste into valuable resources such as fertilizer and gas energy through biodigester processing and other economically viable methods.

Abstract

This study aims to measure the environmental costs (eco-cost) and the eco-efficiency ratio rate (EER) of the production of pencils and formulate some recommendations to improve the manufacture sustainability. The measurement of Eco-efficiency was performed using life cycle assessment (LCA) with the eco-cost method. The pencil manufacturer produces a waste of 20 %, and the product rejects 37 %. The material used is wood, slat, and chemical material for painting. The result of the data processing shows that the eco-costs of IDR 50.593.583 for 4200 grosses production lot size. The eco-efficiency index or EEI for pencil product was 1,69, which means that the products are affordable and sustainable. The eco-efficiency ratio rate (EER) is 41% means that pencil production processes need improvement. The single score Impact Category Diagram shows that the most significant environment impact category is climate change. The recommendation to improve the EER of pencil production based on Impact Category Diagram is (1) to increase the utilizing of wood waste and (2) to increase the capability of technicians and operators to reduce the product rejection. These recommendations aim to reduce the wood consumed in production.
