Porang is a tuber plant that has the potential to develop because it has export market opportunities as industrial raw material. Tegalwaru District, Karawang Regency is one of the areas that produces porang, to cultivate porang requires a large enough capital to become one of the obstacles to porang farming. This study aims 1) to determine the amount of acceptance and income of porang farmers in Tegalwaru District, Karawang Regency and; 2) to obtain information on the profit and loss of porang farming in Tegalwaru District, Karawang Regency. The research method used is a case study. This research was conducted from June to July in Tegalwaru District, Karawang Regency. Sampling technique using saturated sampling method. Data collection uses primary data and secondary data. The analysis used is revenue, revenue, R/C, revenue BEP, production BEP and price BEP and payback period. The results showed an average total cost of IDR 67,126,783 per planting season, an average revenue of IDR 156,482,759. per planting season and an average income of Rp 89.818.919. R/C Ratio value of 2.33. The BEP value of revenue is Rp. 2,407,468, - the production BEP is 601,87 kg and the price BEP is IDR 1,715/kg. The payback period for porang farming is 7 months

Ornamental fish is one of the commodities that are in demand by the public, especially in urban areas. Ornamental fishmongers need to pay attention to the tastes of consumers in order to maintain and increase their sales turnover.  This study is aimed at: identifying consumer characteristics, analyzing consumer preferences in buying ornamental fish, analyzing the factors of that influence consumer decision making in the purchase of ornamental fish at the Bekasi City Ornamental Fish Promotion Center.   This study used  primary dor primary taken by interview technique using questionnaires. Accidental sampling of 100 ornamental fish consumers. Secondary data were obtained from the relevant agencies in this study, namely data from BPS and literature studies. Analysis techniques used: Likert scale, descriptive, and multiple linear regression. The results of the study: Ornamental fish consumers are dominated by men with an age range of 22 years to 28 years, the final education level of Bachelor (S1) work is dominated by Private Employees, and the income level is Rp.2,500.000 - Rp. 5,000,000/month;  Consumer preferences are influenced by the color and pattern of ornamental fish, the purpose of buying for entertainment or hobbies, the type of ornamental that is most in demand is chana, the frequency of purchases per consumer is an average of 2-3 heads,  the purchase is dominated by buying different types of fish and aquarium equipment   , friend as information,  reasons for buying and satisfaction, namely the variety and availability of fish species;  Simultaneously factors: cultural, social, personal, psychology have a significant influence on purchasing decisions.  Partially personal factors (X3)  and factors of psychology (X4) have a marked effect on consumer  decision-making   in the purchase of ornamental fish with koefisien  positive.  Fcultural actors (X1), and social factors (X2) have no real effect on the purchasing decision of ornamental fish.

ABSTRAKIndonesia memiliki potensi produksi akuakultur yang besar. Pada sektor perikanan, budidaya ikan diupayakan untuk memanfaatkan sumber daya air terbatas. Faktor yang memengaruhi kualitas dan pertumbuhan ikan adalah oksigen terlarut (dissolved oxygen). Microbubble generator (MBG) menjadi solusi untuk menyelesaikan masalah oksigen terlarut (DO) dalam air. Pengabdian ini akan melakukan modifikasi MBG tipe orifice dengan pipa porous dan pipa distributor. Selanjutnya mengkaji tentang pengaruh pipa distributor dengan variasi parameter pengujian terhadap stabilitas harga DO yang seragam pada air di kolam ikan. Pelaksanaannya akan melibatkan proses perancangan alat yang menghasilkan drawing design. Maka akan diteruskan ke proses pembuatan alat, setelah itu diuji fungsinya. Tahap akhir proses pengujian dalam air di kolam tanpa ikan untuk memperoleh harga DO yang stabil dan seragam. Dengan tujuan masyarakat dapat mengetahui, mengoperasikan, merawat, membuat alat secara swadaya (mandiri). Estimasi masyarakat mengetahui dari hasil kegiatan ini berkisar 84%. Hal ini ditinjau dari saat di lapangan dan taha evaluasi/monitoring telah dilakukan. Selain itu masyarakat mendapatkan dampak perekonomian yang positif, khususnya untuk komunitas peternak ikan skala kecil dan menengah yang tidak memiliki fasilitas seadanya. Kata kunci: dissolved oxygen; microbubble generator; orifice type; drawing design. ABSTRACTIndonesia has a large potential aquaculture production. In the fisheries sector, fish farming is sought to utilize limited water resources. Factors that affect the quality and growth of fish are dissolved oxygen (dissolved oxygen). Microbubble Generator (MBG) is the solution to resolve dissolved oxygen problems (DO) in water. This service will modify the ORIFICE type MBG with Porous pipes and distributor pipes. Furthermore, examine the influence of distributor pipes with variations in testing parameters on the stability of the price of DO uniformly on water in the fish pond. The implementation will involve the design process that produces drawing design. Then it will be forwarded to the tool making process, after which it is tested. The final stage of the testing process in water in a pond without fish to get a stable and uniform do price. With the aim of the community can know, operate, care for, make tools in self-help. Community estimates knowing from the results of this activity ranging from 84%. It is reviewed from the moment in the field and the evaluation/monitoring has been done. In addition, the community gets a positive economic impact, especially for small and medium-sized fish farmers who do not have makeshift facilities. Keywords: dissolved oxygen; microbubble generator; orifice type; drawing design.
