This study aims to review the literature in reducing carbon emission from supply chain system for the past few years and presenting drivers, barrier, performance indicator, and practice. The issue of reducing carbon emission become frequently discussed since unplanned and irresponsible actions by industries are potential threats to sustainability. Companies are now trying to minimize environmental impacts by integrating environmental concerns into their supply chain operations. In the aim of reducing carbon emissions, the industry is faced with different drivers, barriers, and performance indicator. With a variety of problems faced, the practices taken to reduce carbon emissions are very diverse. Thirty papers were collected from previous studies and linked to discussion points. The result showed that good coordination with various media in the supply chain system would be able to achieve common goals in reducing gas emissions.

The implementation of AEC (Asian Economic Community) leads to demand increase at ports in Indonesia. This increasing demand is followed by operational efficiency at the port as well. In fact, ports in Indonesia have an average dwell time for 5 days. One of the causes of this long dwell time is container transfer inefficiencies during loading process. In this research, we will focus in yard management and increasing land utilization. To increase the land utilization, we develop the space-sharing concept to reduce the initial space needed for a given workload. Since the ships arrivals are also varying, this concept will be possible. We develop the concept by adding uncertainty on number of incoming containers at operational level as the determining factor in planning a shared yard area. We propose a simulation approach to evaluate strategies in making yard template.

In practice, the policy of delaying payment periods is prevalent between players in a supply chain system. Generally, payments made at the end of the permitted period. Supply chain management is one of the keys to corporate sustainability that the activities have an impact on the environment.  This paper aims to develop an integrated green supply chain model with a permissible delay in payment consideration. In this research, the author develops a mathematical model to find the effect of delay in payment on emissions costs without ignoring the economic performance of a supply chain. The author develops four different scenarios model. Furthermore, numerical experiments and sensitivity analysis tests were conducted. Result of the study shows that delay in payment is integrated players into the supply chain system.  It has a positive impact on reducing supply chain emissions costs.

Vehicle Routing Problem (VRP) has many applications in real systems, especially in distribution and transportation. The optimal determination of vehicle routes impacts increasing economic interests. This research aims to find the optimal solution in Vehicle Routing Problem Pick-up and Delivery with Time Windows (VRPPDTW).  Targets of this problem included reducing distance travel and penalties. Three penalties that were considered are a capacity penalty, opening time capacity, and closing time capacity. An improved genetic algorithm was developed and used to determine the vehicle route.  There were one main depot and 42 customers. This research raised the problem of a shipping and logistics company. Analysis of the results showed that the proposed route obtained from improved genetic algorithms (GA) was better than the existing route and previous algorithm. Besides, this research was carried out an analysis on the effect of the number of iterations on distance traveled, the number of penalties, and the fitness value. This algorithm could be applied in VRPPDTW and produces an optimal solution.

Manukan adalah salah satu desa di Kabupaten Bojonegoro yang terletak di Kecamatan Gayam, Bojonegoro, Jawa Timur. Minimnya penghasilan keluarga dari profesi petani menuntut masyarakat untuk lebih kreatif dalam meningkatkan pendapatan keluarga. Bojonegoro memiliki potensi batik Jonegoroan yang menarik dan banyak diminati. Namun, tidak banyak masyarakat Bojonegoro yang memiliki pengetahuan dan ketrampilan membatik. Sehingga, perlu dilakukan pemberdayaan Ibu-ibu dalam mengembangkan industri kreatif Batik Jonegoroan. Pemberdayaan ini dilakukan melalui empat tahapan, yaitu sosialisasi Batik Jonegoroan, pelatihan cara membatik, pelatihan pengembangan industri kreatif batik dan pemasaran hasil batik. Dalam pelatihan ini, peserta dilatih untuk memahami dan mempraktikkan proses membatik dengan empat teknis pewarnaan dan perbedaan antara batik cap dan batik tulis. Teknis pewarnaan yang dipelajari meliputi teknik coletan, semok, kelengan dan laseman. Hasil pelatihan berupa kain batik Jonegoroan dipamerkan dan dijual secara online di marketplace dan media sosial, sedangkan secara offline di bazar dan pameran batik. Pengetahuan dan ketrampilan ini dapat dijadikan bekal untuk membuka peluang usaha pengrajin batik oleh ibu-ibu desa Manukan sebagai salah satu upaya meningkatkan pendapatan keluarga.
