Reduce Carbon Emissions of Logistic Transportation Using Eight Steps Approach in Indonesian Automotive Industry

The global competition encourages Indonesia to advance the economy, especially in manufacturing by implementing sustainable manufacturing. Companies must consider transportation costs and concern for the environment due to the large increase in greenhouse gas emissions and the increase in NOx, Particulate, and various other harmful pollutants. Emissions from transportation activities cause global climate change and damage air quality and human health in regional and urban areas. At the same time, the movement of empty containers can result in air pollution due to CO2 emissions which have a negative impact on sustainable development. This study aims to reduce carbon emissions in the logistics transportation chain in the Automotive Manufacturing Industry. The method used is the Eight Step Approach. The method used is systematic and structured from defining the problem to standardizing improvements. Analysis of the causes of the problem and proposed improvements are determined by Focus Group Discussion (FGD) with expert judgment. The source of the data obtained comes from field observations, FGD, company reports from 2019 to 2021. This research has proven that reducing carbon emissions has an impact on company profits. The largest decrease was contributed by improvements in transportation routes. The ratio of reducing carbon emissions by 2020 is 2.6% or an increase in efficiency compared to the previous year.

Verification Simulation and Development of New Marine Transport Model

The structure of the global supply chain creates an imbalance in trade between regions of the world. It creates many empty containers on the ocean shipping route. Focusing on this problem, we will develop an empty container relocation plan for empty containers in a marine container logistics network connecting multiple bases and propose a model that minimizes the total cost of container transportation. The proposed model was verified by the simulation designed and developed in this study, and the effectiveness of the proposed model was shown by the data of the marine transportation company.

A cross sectional survey of knowledge, attitude and practices related to the use of insecticides among farmers in industrial triangle of Punjab, Pakistan

Pesticides in Pakistan are abundantly utilized for pest control in agriculture sector. The over and unsafe use of insecticides plus poor handling leads to the development of resistance, outbreak of secondary pests and hazardous impact on environment. The present study was aimed to access the current knowledge, attitude and common practices of farmers about the use of insecticides against pest in industrial triangle of Province Punjab, Pakistan. This study was conducted during October 2019 to February 2020. In this study farmers (n = 300) took part from three localities of Province Punjab (Gujrat, Gujranwala and Sialkot). Farmers were interviewed using a questionnaire to collect data about the knowledge of pest control by use of chemical method, biological method and combination of both to eradicate the pests. The result shows almost all (93%) farmers were male and they did not know about the insecticides mode of action and its chemical composition. They do not have any knowledge about the biological control of pests and did not get any assistance or help from Agriculture Extension Officer. They even did not properly dispose off the empty containers of insecticides. Statistical analysis reveals that lack of education and awareness about biological control of pest depicts development of resistance and outbreak of secondary pest including health hazards and environmental pollution. Poor understanding about pests, abundant use of insecticides, incorrect perception about application of insecticides and negligence regarding biological control shows that there is need to initiate public awareness programs to ensure the application of integrated pest management (IPM) and sustainable agriculture.

A Multi-Stage Approach for Empty Container Repositioning Under Coordination Among Liner Carriers

This paper studies the empty container repositioning (ECR) problem considering the exchange of slots and empty containers among liner shipping companies. It is common for an individual shipping company to seek an optimal solution for ECR and cargo routing to maximize its own benefits. To achieve cooperation among shipping companies, a multi-stage solution strategy is proposed. With the inverse optimization technique, the guide leasing prices of slots and empty containers among shipping companies are derived considering the schedule of vessels and cargo routing. Based on the guide leasing price, a cooperative model is formulated to minimize the total cost, which includes the transportation cost for laden containers, the inventory holding cost, the container leasing cost, and the repositioning cost. All the involved shipping companies are expected to follow the best solution of ECR and cargo routing to achieve a cooperative and stable optimum. A real-world shipping network operated by three liner shipping companies is used as a case study with promising numerical results.

Do Foldable Containers Enhance Efficient Empty Container Repositioning under Demand Fluctuation?—Case of the Pacific Region

This study considers the empty container repositioning problem of shipping companies that use standard and 3-in-1 foldable containers with more advanced designs. A mathematical model is developed to compare the total management costs of container repositioning of various patterns in different cargo shipping demand scenarios. Numerous scenario analyses and simulations of empty container repositioning were conducted, focusing on a liner shipping service in the Pacific Islands where empty containers are likely to be present because of the imbalance between inbound and outbound flows of containers, including static analysis and consecutive analysis with demand fluctuation in different approaches. Results show that with the introduction of foldable containers, depending on the growth rate of container cargo shipping demand, the total management costs of empty container repositioning can be reduced. However, introducing a large number of foldable containers may increase the total management costs of container repositioning. Moreover, the cost reduction effect of adding another containership increases in cases where future cargo shipping demand increases substantially. Furthermore, the introduction of foldable containers not only effectively reduces the management costs of empty containers, but also makes costs more stable and predictable.

Assessment of the pesticide use, practice and hazards on cotton growing farmers in the Awash Valley Ethiopia.

Pesticides are commonly used in the prevention or control of pests such as insect pests, mites, disease, and weeds in crops to increase production and productivity. The aim of the current study was designed to assess the pesticide utilization, practice, pesticide-related knowledge, and perception of farmers and to evaluate the protective measure taken by the farmers. For this purpose, field surveys were carried in Amibara, Gewane, Assayita, and Fentale districts during the 2019 main crop cropping season. A total of 128 small-scale holder farmers, 25 large-scale holder farmers, 30 sprayers, and 12 extensions were interviewed closed and opened questioners. The results revealed that the majority of farmers (44.5%) between the age of 41 and 50 years old, while only fourteen those (9.4%) were more than 51 years old. Regarding the educational level of smallholder farmers, 49.2% were illiterates, 27.9% elementary school, 17.0% secondary school and 5.8% had completed high school. The majority of sprayers (66.7%) were elementary school level. The unsafe and indiscriminate use of pesticides in agriculture represents a major hazard to the environment and human health. All farmers (100%) acknowledged that pesticides were harmful to their health and the environment. Over 63.2% of the farmers did not read or follow pesticide label instructions, and 78.5% did not use any personal protective equipment during spray operation and formulation pesticides. When disposing of pesticide empty containers, respondents adopted unsafe practices such as through near irrigated canal, burning, dumping in the field, domestic use, and burying. Less than 50% of smallholder farmers obtained training on pesticide use 14.8%, application method 16.6%, disposal of empty container 13.3%, and storage and safety 10.2%. Results also demonstrated that all farmers showed poor practices regarding the disposal of empty pesticide containers. The present study revealed that the utilization and practices of pesticides in irrigated cotton-producing areas in the Awash Valley of Ethiopia. It also demonstrated the role of retailers, importers, and state extension workers in providing information and advice to the farmers. Future researches should focus on the merit and demerit of mixing two or more pesticides to control insect pests and on the evaluation of different pesticide resistance development against a variety of insect pests in cotton-growing areas.

Is the Environmental Behavior of Farmers Affecting Their Pesticide Practices? A Case Study from Greece

Policymakers often assume that farmers with pro-environmental behavior are more likely to follow proper pesticide practices and thus, in order to improve the safety of their pesticide practices, they implement strategies and programs designed to raise environmental awareness among the general public. The aim of this paper is to examine whether pro-environmental behavior can instigate proper pesticide practices among farmers. According to our results, farmers’ environmental behavior does not affect their pesticide practices and thus strategies aiming at raising environmental awareness among the general public would not prompt them to follow proper pesticide practices. In addition, the respondents reported following overall proper practices such as wearing masks and appropriate clothes during sprayings as well as rinsing the empty containers by performing the triple-rinse method. However, they did not wear gloves during applications, and many disposed the remaining pesticide concentrate to non-arable land. To conclude, in order to improve farmers’ pesticide practices, strategies and programs specifically designed for farmers must be developed because those addressed to the general public would not be effective. Moreover, certain improper practices found in this study ought to be addressed by policymakers and actors involved in the agricultural sector.

Knowledge, Attitude, and Practice of Farmers on Pesticide Use and Their Impacts on the Environment and Human Health From Small Scale Vegetable Farming Along the Littoral of Lake Ziway, Ethiopia

Background: The insecure utilization and misapplication of pesticides in Ethiopia are major fears to farmers' wellbeing and the ecosystem. This study aimed to assess the level of knowledge, attitude, and practices of the small-scale vegetable farmers towards the use of pesticides in Ethiopia along the littoral of Lake Ziway. Methods: It was a cross-sectional study involving a total of 210 farmers randomly selected during pesticide application from a purposively selected irrigation-using village located in the immediate vicinity of Lake Ziway. Data were generated through structured in-depth interviews and observations on-farms. A chi-square test was applied to evaluate whether the collected data and their probable association were significant. Results: The results show that WHO class II pesticides (moderately toxic) are the most frequently used pesticides in the study area. The use of WHO classes 1a and 1b and banned or restricted pesticides such as DDT and Endosulfan were not reported. A great portion (92%) of farmers indiscriminately disposed of empty containers in the field while 86.7% apply the leftover pesticides to other crops. More than 90% of small-scale farmers did not use any personal protective equipment (PPE) when handling pesticides. About 95% of farmers had poor knowledge regarding pesticides. A significant association (p < 0.001) was observed between the knowledge of the farmers and their practices related to the pesticide. Conclusion: Generally, the Knowledge of small-scale farmers on pesticides was poor. Moreover inappropriate disposal of pesticides and its container will damage the environment. The finding of the study underlines the need to train framers concerning the safe and proper use of pesticides to prevent health and environmental hazards.

A Decision-Making Tool for the Optimization of Empty Containers' Return in the Liner Shipping: Optimization by Using the Genetic Algorithm

This article describes how in the maritime transportation sector, containerization represents one of the most remarkable improvements. In fact, the different shipping companies provide great efforts, whose purpose is to reduce the cost of this transport. However, these companies are facing a problem of empty containers, which are not available at some ports of Maritime Transport Network (MTN) to meet the clients' demands. This problem is simply a consequence of the imbalance in the distribution of containers through the MTN due to the set of containers that do not return to the origin port. This work offers a decision-making tool to this problem by proposing an optimal return of empty containers. The proposed application is based on evolutionary heuristics. Its principle is to find an optimal solution from a set of several feasible solutions generated during an initial population in order to enable the search of empty containers at lower cost.
