Abstract:Abstract: The global transition towards sustainable food systems faces significant challenges in vegetarian food supply chains, including transparency issues, distribution inefficiencies, and quality verification problems.…
s. This research proposes VegeChain development, a decentralized marketplace ecosystem based on smart contracts designed to transform vegetarian food supply chains and accelerate Meatless, Balanced, Green (MBG) program adoption. Using mixed-method methodology integrating blockchain system design, stakeholder analysis, and economic simulation, this research develops a comprehensive technology framework combining blockchain transparency, smart contract automation, and sustainable tokenomics with novel mathematical models. The system implements dynamic pricing algorithms based on Automated Market Maker (AMM) mechanisms, multi-objective optimization for supply chain efficiency, and reputation-based consensus protocols. Simulation results demonstrate that VegeChain implementation can improve supply chain efficiency by 35%, reduce food waste by 28%, and increase consumer trust by 42% measured through validated stakeholder satisfaction surveys (n=456) using 5-point Likert scales with statistical significance p<0.001. Technical innovations include Byzantine Fault Tolerant consensus with 99.9% reliability, gas optimization achieving 67% cost reduction, and real-time quality verification algorithms with 98.7% accuracy.

Abstract:Abstract: Central Java has significant potential in the plantation sector with various commodities such as pepper, cloves, tobacco, tea, sugarcane, coffee, nutmeg, and patchouli. However, the abundance of commodities does…
s not guarantee that all of them provide maximum benefits. This study aims to recommend the most potential plantation commodities for development. The research utilizes plantation data from Central Java over the past few years, obtained from Satu Data Indonesia, covering land area, production, productivity, and the number of farmers. The evaluation criteria include land area, production, productivity, and the number of farmers. In the decision-making process, a Decision Support System (DSS) approach is applied using the Multi-Attributive Border Approximation Area Comparison (MABAC) method and the Preference Selection Index (PSI). The MABAC method is used to determine rankings, while PSI is used for criteria weighting. The results indicate that sugarcane, tobacco, and robusta coffee are the best commodities, with final scores of 0.419, 0.237, and 0.020, respectively. Therefore, it can be concluded that the most potential commodities for development in Central Java are sugarcane, tobacco, and robusta coffee.

Abstract:Abstract: Welfare is one of the things that determines the progress of a region, to achieve the welfare of its people, especially in the economic sector, a technique is needed to measure welfare that continues to change.…
This study aims to analyze the differences in the level of community welfare in Central Java Province by grouping regions based on several indicators. Grouping is done using data from various sources that include the main indicators of welfare. The method used in this study uses the K-Means data mining algorithm to group regional data according to their level of welfare. The results of the analysis divide the regions into three categories: Medium Welfare Level, which includes Banyumas, Purworejo, Boyolali, Klaten, Sukoharjo, Karanganyar, Sragen, Kudus, Jepara, Demak, Semarang, Kendal, and Pekalongan City and Tegal City, High Welfare Level, consisting of Magelang City, Surakarta City, Salatiga City, and Semarang City; and Low Welfare Level, covering Cilacap, Purbalingga, Banjarnegara, Kebumen, Wonosobo, Magelang, Wonogiri, Grobogan, Blora, Rembang, Pati, Temanggung, Batang, Pekalongan, Pemalang, Tegal, and Brebes Regencies. The findings show that the C2 region has a longer average length of schooling, higher per capita expenditure, and better HDI, reflecting a higher quality of life. This study provides an overview of welfare inequality in Central Java Province and suggests the need for more focused policies to improve the quality of life in each category of region.

o overcome this problem, forecasts are made so that later, the government can take policies to control and suppress the unemployment growth rate. This research aims to predict unemployment in Indonesia in 2023 using the Weighted Moving Average method, widely used to determine the trend of a time series, which is part of one of the Time Series methods that gives different weights. The dataset used was obtained from the Central Statistics Agency (BPS) relating to unemployment data from 2000 to 2022 (23 years). To analyze the level of accuracy of the results of this unemployment forecast using the MAD, MSE, and MAPE methods. This research concludes that the Weighted Moving Average method can be applied in predicting unemployment in Indonesia in 2023. The results of this research are a prediction of the number of unemployed in Indonesia, as many as 8,874,942 people at a weight value of 3 (three) where the accuracy of the MAD value is 745786.1833, the MSE value is 948402050986.3 and MAPE is 8.28%.

rs. Partners who do data processing that has been done on data in the field. In this case, the acceptance of new partner candidates is quite often held to carry out survey and population census activities. The partner acceptance process is less effective because it still uses the manual method, namely the approach between existing partners. So we need a decision support system that can help election performance to be more effective. The basic concept of the Simple Addictive Weighting method is to find a weighted sum of performance ratings for each alternative on all criteria or attributes. The purpose of this research is to build and design a data processing application for prospective new partners at the Central Bureau of Statistics of the Asahan district to get an assessment according to the specified criteria. The results of the research conducted produced the best alternative decision, namely Ruslan Efendi with a score of 0.975 and Yenni Yulistina with a value of 0.95. based on these results can assist the Central Bureau of Statistics in determining the assessment of potential new partners so that they can provide a reference in decision making. In accordance with the criteria required by the Central Bureau of Statistics.

e control plane and the data plane. Where the control plane will be placed on the controller that is stored and provides all the needs that exist in the network system. In Software Define Network, it still needs a lot of research, especially security, because it is the most important part in the network. One solution that can be used as security is a firewall. With the firewall, every data traffic will be monitored and also determine the entry and exit of data. In this research, a firewall will be implemented at the data link layer which will use a tree topology in the software define network and POX as the controller. The results of this study produce a firewall program with the python programming language which is placed on the POX controller. The code modification has successfully blocked, controlled, and monitored each packet based on the rules on the firewall.

Abstrak: Software Defined Network belakangan ini menjadi satu arsitektur baru pada sistem jaringan komputer yang menawarkan satu kemudahan dengan sistem kontrol terpusat. Pada arsitektur Software Defined Network akan memisahkan control plane dan data plane. Dimana control plane akan ditempatkan pada controller yang bertugas mengatur serta menyediakan segala keperluan yang ada pada sistem jaringan. Pada Software Define Network masih perlu dilakukannya banyak riset khususnya bidang keamanan, karena keamanan merupakan bagian terpenting dalam jaringan. Salah satu solusi yang dapat digunakan sebagai keamanan adalah firewall. Dengan adanya firewall maka setiap lalu lintas data akan dapat dimonitoring dan juga menentukan keluar masuknya suatu data. Pada penelitian ini akan diimplementasikan firewall pada data link layer yang akan menggunakan topologi tree pada software defined network dan POX sebagai Controllernya. Hasil pada penelitian ini menghasilkan satu program firewall dengan bahasa pemrograman python yang ditempatkan pada pox controller.
