SPP Bandung plays a role in managing the distribution of shipments effectively and efficiently. SPP Bandung handles two types of distribution, namely primary distribution outside the Bandung area and secondary distribution to 12 distribution centers within the Bandung area. Currently, SPP operates six fleets to serve both types of distribution. However, the current distribution system has not optimized the fleet capacity, resulting in a waste of time and resources. This study uses a quantitative approach to analyze and develop an optimal distribution route strategy. By applying the saving matrix, nearest insertion, and nearest neighbor methods, the analysis results showed a decrease in total mileage from 261.8 km to 249.6 km and fuel cost efficiency from Rp210,377.33 to Rp198,539.33. The aving matrix method proved to be effective in route optimization, but other methods can also be considered for maximum improvement.

Wasted food is a global issue that has been around for a long time but has become increasingly serious without realizing it. The resulting impacts negatively affect many sectors, such as the environment, economy and social. Food waste can reduce farmers' income and increase consumer spending. Households can be said to be the biggest contributors to food waste because apart from daily consumption activities, the most dominant livelihood system of the people in Teriak sub-district is farming. The characteristics of farming households that play a major role in meeting household food needs are the socio-economic conditions of farmers, because it can describe the capacity of farmers in meeting their food needs, research was conducted on the causes of food waste behavior by farming households, especially Teriak District. This research aims to determine household consumption behavior towards the emergence of food waste and identify the influence of socio-demographic and socio-economic factors on food waste behavior by households in Teriak District, Bengkayang Regency. The research method used in this research is descriptive statistics with 100 sample respondents representing households. The variables in this study are divided into two, namely socio-demographics and household behavior. The research results show that the behavior of farming households is influenced by socio-demographic and socio-economic characteristics of respondents such as age, length of education, number of family members, income and expenses. Food waste behavior includes several aspects such as the social environment, purchasing, storage, processing and consumption.

Regional Head Elections (Pilkada) are democratic processes conducted to elect Governors and Deputy Governors, Regents and Deputy Regents, as well as Mayors and Deputy Mayors. The General Election Supervisory Agency (Bawaslu) is the authorized institution responsible for overseeing the implementation of elections, including their various stages. Campaigning is an integral component of the election process, during which candidates utilize campaign props (Alat Peraga Kampanye/APK) to promote themselves to the public. In Lebak Regency, numerous violations have occurred regarding the installation of such props, underscoring the critical role of Bawaslu Lebak in ensuring compliance. This study aims to examine the authority exercised by Bawaslu Lebak Regency in supervising the installation of campaign props during the 2024 regional elections and to identify the challenges encountered. The research employs the theory of authority and the theory of supervision, using an empirical juridical approach and an analytical descriptive specification. Primary data supported by secondary data were obtained through interviews and document analysis. The findings indicate that Bawaslu Lebak Regency implements both preventive and repressive supervisory measures. Preventive efforts include issuing advisories, conducting public outreach, and inter-agency collaboration, while repressive actions involve processing reports and findings of violations, as well as dismantling noncompliant campaign materials. The agency faces several obstacles, including low awareness among candidates and campaign teams regarding legal compliance, limited personnel for enforcement activities, resistance from various stakeholders, and the environmental issue of accumulated campaign waste.

This research is motivated by environmental problems caused by campaign props (APK) waste that is not properly managed after election campaigns end. Current regulations focus only on the installation and removal of APK but do not comprehensively address waste management. The purpose of this study is to analyze how APK waste management policies can align with environmental sustainability principles, as well as how election organizers and Bawaslu can support more environmentally friendly campaigns. This study uses normative legal research methods with statutory and conceptual approaches. The findings indicate that stricter and more synchronized policies are needed between election regulations and environmental regulations, including the application of reduce, reuse, recycle (3R) principles, the use of environmentally friendly campaign materials, as well as education and sanctions for election participants. The implications of this study are expected to encourage improvements in regulation and collaboration between institutions so that election campaigns not only uphold democratic principles but also support environmental sustainability.

This study aims to examine the impact of waste on natural ecosystems in the Karawang area, West Java. As one of the largest industrial estates in Indonesia, Karawang faces serious challenges related to industrial and domestic waste management. Poorly managed liquid and solid waste has polluted rivers, farmland, and forest areas, and disrupted the balance of local ecosystems. This study uses a qualitative approach through field observations, interviews with residents and related agencies, and secondary data analysis. The results of the study show that waste pollution has a direct impact on the decline in water quality, habitat damage, and the decline in biodiversity at several points in Karawang. In addition, the surrounding community also feels the impact through health problems and reduced agricultural yields. This study recommends the need to strengthen waste management regulations, increase supervision of industry, and involve the community in environmental conservation efforts. These findings are expected to be considered in the formulation of sustainable environmental policies in Karawang.

Based on research conducted using normative and empirical juridical methods at Class I and IIA Correctional Institutions in Bandar Lampung, the implementation of wage rights for inmates participating in independence development programs as mandated by Law No. 22 of 2022 and Government Regulation No. 32 of 1999 shows that the wage distribution mechanism (50% incentive for inmates, 35% for development funds, and 15% to the state treasury) has been executed through collective labor agreements and an integrated bookkeeping system. The results indicate that over 70% of inmates actively participate in productive activities such as carpentry and handicrafts, with an average wage increase of 15% within one year due to innovations in waste-based craft products. However, productivity varies between activities (85% of target in woodworking versus 60% in sewing) due to raw material constraints, and wage disbursement is delayed by an average of 10 working days because of manual verification procedures and report synchronization. To optimize this system, it is recommended to increase the number of coaching and administrative staff, improve production facilities, digitize bookkeeping and inmate savings accounts, and diversify programs according to local market needs.

Public awareness is needed to reduce the use of single-use plastics. One effort to reduce plastic waste is by replacing chemical-based materials with natural alternatives. This study aims to analyze the effect of beeswax thickness on the type of fabric used. A quantitative method was applied by measuring the thickness of each material sample with beeswax mass variations of 10 grams, 15 grams, and 20 grams. The results showed that blacu fabric with 15 grams of beeswax had a “very good” coating thickness. Blacu fabric with 10 grams of beeswax had a “good” thickness, while 20 grams resulted in a “fair” thickness. The thickness of the fabric material varied according to the beeswax mass and affected the coating uniformity of beeswax applied to the fabric surface.

This study analyzes the use of non-standard words in a thesis entitled "Effectiveness of Waste Management Based on Reduce, Reuse, Recycle (TPS 3R) Waste Disposal Sites at TPS Jokotole, Barurambat Timur Village, Pademawu District, Pamekasan Regency". The use of language is an essential thing in communicating, both orally and in writing to convey messages and information so that they are conveyed effectively. However, language errors are often found, especially the use of non-standard words, even by someone who has a deep understanding of Indonesian language rules. The use of standard language is very important to avoid misunderstandings, especially in the context of scientific writing such as theses. This research method uses a descriptive qualitative method with data collected then analyzed, classified, and evaluated standard and non-standard vocabulary based on KBBI. The results of this study indicate that many uses of non-standard words include errors in phonology, morphology, use of the preposition "di", punctuation, and non-standard spelling errors, as well as word wasting. These errors are mostly caused by habits, the influence of foreign languages, and a lack of understanding of standard language rules. The research findings highlight the importance of understanding the application of standard language rules in scientific writing to improve the quality of students' writing.  

In response to increasing competition in the manufacturing sector, PT X—a copper busbar manufacturing company—implemented Lean Manufacturing supported by Value Stream Mapping (VSM) to improve production efficiency and reduce supply chain costs. This study utilizes VSM, Value Stream Analysis Tools (VALSAT), and Root Cause Analysis (5 Whys) to identify sources of waste and formulate improvement strategies. The analysis identified three dominant wastes: waiting time, product defects, and excess inventory. These were mainly caused by the lack of standardized material procedures, inadequate supporting equipment, and poor integration between the incoming inspection process and the Enterprise Resource Planning (ERP) system. To address these issues, the study proposes installing silica rolls, providing air wipers and flatness tools, developing standardized work instructions, and integrating Internet of Things (IoT) technology with the ERP system for real-time monitoring. As a result of implementing these solutions, PT X successfully reduced its defect rate from 6.23% to 1.32%, decreased lead time, and achieved notable savings in supply chain costs. The findings demonstrate that integrating Lean Manufacturing principles with VSM can effectively eliminate non-value-added activities, streamline production processes, and enhance overall competitiveness. This study reinforces the strategic value of Lean tools in continuous improvement initiatives within the manufacturing industry.

Turmeric is a spice commodity that has high economic market potential. However, the utilization of turmeric, especially in Kunden Village, Sukoharjo Regency is still limited in terms of processing innovation, and creates organic waste that has not been optimally utilized, namely turmeric leaves.
