Abstract

In generally, the vessel takes on ballast water as it unloads cargo and discharges ballast water as it loads cargo. It is estimated that approximately 7 billion tons of ballast water is transferred globally each year. The total volume of ballast water onboard a ship can be in excess of 5,000 m3. The organisms and pathogens in the water are not necessarily evenly distributed i.e. there may be patches with higher densities. Int his research, we implement micronbubble technology for Ballast Water Treatment. Principally, bubble could be developed in liquid or gas form. The micro term in microbubble reflects to the proportion which is usually in micrometer of its diameter size. Smaller bubble size is expected to give wider surface area as well as affected to greater mass transfer between its surface and interfacial area. Microbubble characterisation was conducted by using high speed camera for bubble size determination. Moreover, a fluidic oscillator was attached into the system to study the efficacy of bubble distribution within ceramic diffuser.

Abstract

Budidaya sayur-sayuran merupakan salah satu peluang bisnis bagi petani, karena komoditi sayur-sayuran dapat diusahakan dan dilakukan oleh sebagian besar rumah tangga petani baik untuk konsumsi keluarga maupun untuk dijual. Desa Samiran merupakan salah satu desa yang berada di antara kaki Gunung Merapi dan Merbabu di Kabupaten Boyolali. Saat ini Desa Samiran terus melakukan upaya pembangunan masyarakat melalui pengembangan dan pemberdayaan masyarakat desa. Permasalahan yang terjadi pada Desa Samiran adalah kegiatan budidaya sayur-sayuranmasih dilakukan terbatas dilahan-lahan pertanian yang umumnya berada di lereng-lereng gunung. Sedangkan lahan pekarangan disekitar rumah mereka hanya dibiarkan terbengkalai.Hal ini sebagai akibat karena, minimnya pengetahuan dan keterbatasan dalam hal penguasaan teknologi, mengakibatkan kurang berdayanya masyarakat tani dalam mengusahakan dan mengembangkan lahan pekarangan rumah sebagai tempat bertanamam tanaman sayur-mayur.Akibatnya, lahan pertanian menjadi sakit dan semakin miskin hara serta produktivitasnya semakin rendah. Tujuan dari kegiatan pengabdian masyarakat ini adalah meningkatkan pengetahuan dan keterampilan masyarakat petani di dalam pengelolaan lahan pekarangan khususnya untuk kegiatan pertanian sayur-mayur yang nantinya dapat membantu di dalam peningkatan ekonomi masyarakat.

Abstract

[Bioconversion of Organic Waste using Balck Soldier Fly (BSF): In Collaboration with Resik Sejahtera Waste Community in Polaman Village, Semarang] In many developing countries, such as Indonesia, waste management remains a major issue. The community generates a large amount of waste, however the method for processing organic waste is still landfilling waste in the Final Processing Site (TPA). The amount of organic waste reached 65.05% in 2010, according to the Assessment and Application of Technology. As a result, organic waste processing solutions are required. The larva of the Black Soldier Fly, known as the maggot, is beneficial to humans and does not spread disease. Maggot is a type of animal feed that is regularly used. Maggots contain 43.42% protein, 17.24% fat, 18.82% crude fiber, 8.70% ash, and 10.79% water, making them a viable protein substitute. Furthermore, maggots are better at degrading organic waste than other insects. Maggot growing is the best way to deal with the community's organic waste problem. Community service activities have increased community members' and the Polaman Village community's knowledge and skills in organic waste processing using maggot media, which can reduce animal feed costs, vegetable compost costs, and increase community members' and the Polaman Village community's income.

Abstract

UMKM ”Bozza” merupakan salah satu UMKM di Desa Meteseh Kecamatan Boja Kabupaten Kendal dengan produksi berupa minuman kesehatan dan jamu dalam bentuk ekstrak dan serbuk instan, salah satunya adalah sari jahe instan. Proses produksi sari jahe instan UMKM ini masih bersifat konvensional, mulai dari pemarutan, pemerasan, kristalisasi, penggilingan, pengayakan hingga pengemasannya. Demikian juga pada proses produksi minuman ekstrak masih terkendala pasturisasi dan sterilisasi dengan cara perebusan konvensional sehingga tidak ada kontrol maupun kendali suhu yang mengakibatkan kualitas dan higienitasnya tidak terjamin. Oleh karena itu, adanya solusi dengan menerapkembangkan teknologi berbasis riset agar dapat berkembang lebih baik. Aplikasi alat berbasis riset berupa alat presto dengan konsep hidrotermal subkritis yang digunakan untuk meningkatkan kualitas produktivitas rempah-rempah. Melalui alat ini, senyawa bioaktif gingerol, shogaol, paradol dan zingeron dari jahe akan meningkat sehingga memiliki efek farmakologi seperti: meningkatkan imunitas, antikanker, antioksidan, antikarsinogenik dan antiosteoporosis. Tujuan kegiatan ini adalah meningkatkan produktivitas UKM minuman rempah melalui pengembangan aplikasi teknologi tepat guna, berupa alat presto dengan konsep hidrotermal subkritis. Kegiatan PUPS dilakukan secara terintegrasi, sinergis, dan melembaga antara Sekolah Vokasi UNDIP dan SMK Negeri 3 Kendal serta mitra UMKM Bozza.
