Judul: Spatial Based Decision Support System Model in the Supply Chain of Pangasius.sp Agroindustry in West Java.
Abstrak: Pangasius sp is a freshwater fish commodity that has great potential to be developed and has a high selling price. This is what causes Pangasius sp to receive attention and interest from entrepreneurs to cultivate it. Pangasius fish can be kept in stagnant water conditions and within 6 months of maintenance can reach a length of 35-40 cm. The supply chain encompasses a sequence of operations that encompass the transportation and conversion of primary resources into finalized goods, alongside the dissemination of said goods to ultimate consumers. The supply chain plays a pivotal role in ensuring the uninterrupted operations of businesses and industries, thereby exerting a significant impact on both individual companies and the overall economy. In order to address the intricacies and difficulties associated with these complexities and challenges, it is imperative to establish a proficient decision-making framework for the purpose of effectively managing the supply chain. Supply chain decision-making systems encompass a methodology that relies on data and information technology, integrating analysis, modeling, and real-time information to support decision makers in the optimization of supply chain operations. The utilization of spatial-based decision-making systems holds significance and relevance in addressing the challenges encountered in the catfish agro-industry. Spatial-based decision-making systems utilize geographic information system (GIS) and spatial analysis to aid stakeholders in optimizing supply chain processes, identifying prospective locations, comprehending market demand patterns, and enhancing resource management efficiency. The rapid growth of internet users in Indonesia has influenced various industrial sectors to take advantage of the "information revolution" provided by the internet, including the agribusiness sector. One of the uniqueness of Pangasius.sp is that the fish has a different texture, color and taste from each different region, depending on where the fish is produced. This can be an advantage or a disadvantage, depending on the business strategy to be decided. Traceability is one way to provide more transparency, and it is argued that by increasing transparency production issues in the supply chain can be better mapped and understood, ultimately helping to increase the environmental and social impacts of the supply chain. Consumers are increasingly interested in knowing where and how the ingredients they consume are extracted and produced. Decision makers in the Fisheries and Aquaculture Industry are a matter of complex decisions from day to day. Systems designed to enable decision makers to make informed decisions in dealing with complex problems are called Decision Support Systems (DSS). DSS try to combine domain and technical knowledge and package it in a way that is of practical use to non-scientists. The purpose of this study was to design a spatial-based Decision Support System model in the logistics of Pangasius.sp agro-industry. In designing this main model, supporting models were developed as sub-objectives to support the main objectives of this research, namely: 1) designing a supply chain performance improvement strategy model in Pangasius.sp agro-industry, 2) designing a strategy model for Pangasius.sp agro-industry derivative products, 3) designing a spatial-based information system model for the traceability of Pangasius.sp processing industry products, and 4) designing a spatial-based locating model for patin fish processing units. This research analyzes the

Judul: Sistem Pendukung Keputusan Peningkatan Produktivitas Berkelanjutan pada Manajemen Rantai Pasok Agroindustri Perikanan
Abstrak: The objective of this research was to develop a decision support system for increasing Sustainable productivity on fishery agroindustry supply chain management that provides information and decision alternative to all stakeholders related to catch, effort, added value, agroindustry performance and sustainable fishery in Southeast Maluku District. Stock prediction model measure Value of CMsy and Emsy with equilibrium Schaefer as indicator of surplus production. Added value analysis model use to measure added value with profit margin. Agroindustry performance analysis model use to measure performance of Agroindustry with Balanced Scorecard (BSC) method, terperrate vision and company strategy into four different perspectives, financial, customer, internal Business process, and learning and growth. Sustainable model analysis with MDS method (Multidimensional Scaling). Stock prediction model showed that catch and effort in Southeast Maluku District still below sustainable maximum level. Added value analysis model the result showed that the added value is very low. Analysis agroindustry performance model there sult showed that financial perspective has greatest achievement performance index Sustainability model used to calculate the level of sustainability off isheries in South east Maluku District measured the dimensions of the three- dimensional ecological, social, and economic. MDS results showed that all the dimensions included in the category of less sustainable. The main conclusion of this research is provide information to the agroindustry fishery supply chain actors related catch and effort. added, agroindustry performance, and sustainability fishery in Southeast Maluku District.

Judul: Katalis Zink Ferit Tersubstitusi Cu untuk Oksidasi Benzil Alkohol
Abstrak: Katalis berperan dalam menurunkan energi aktivasi. Katalis ZnFe2O4 dan ZnFe2O4 tersubstitusi Cu disintesis menggunakan metode kopresipitasi untuk digunakan dalam oksidasi benzil alkohol. Katalis dicirikan dengan spektrofotometer inframerah (FTIR) dan difraktometer sinar-X. Spektrum FTIR menunjukkan puncak serapan dari ikatan Zn-O dan Fe-O masing-masing pada rentang 559‒575 cm-1 dan 419‒447 cm-1. Difraktogram menunjukkan terbentuknya fase tunggal Zn0.6Cu0.4Fe2O4 pada katalis ZnFe2O4 tersubstitusi Cu 20%. Benzil alkohol dioksidasi dengan sistem refluks. Konversi benzil alkohol meningkat dengan meningkatnya suhu. Kadar benzaldehida yang dihasilkan dengan katalis ZnFe2O4 tersubstitusi Cu 20% lebih tinggi dibandingkan dengan katalis ZnFe2O4 yang tidak tersubstitusi dan yang tersubstitusi Cu 60 dan 80%. Hal tersebut menunjukkan bahwa katalis ZnFe2O4 tersubstitusi Cu 20% memiliki kinerja yang lebih baik dalam oksidasi benzil alkohol menjadi benzaldehida dengan kadar benzaldehida 8.763%.
