Tamangapa village, Ma’rang district is part of the community development program conducted by Universitas Muslim Indonesia in Pangkajene Kepulauan regency. The local shrimp farmers of Tamangapa village have been facing major issue due to expensive artificial feed and high mortality rate. In order to solve the needs of feed and high mortality rate for farmed fish or shrimp, the source of the natural ingredients using kopasanda leaves Chromolaena odorata L is required. The use of a natural ingredient is also used to prevent the vibriosis using simple technology such as the utilization of local raw materials which is affordable and locally available. The present community service aimed to provide the proper knowledge and skills to members of the fish/shrimp farmer’s group through counseling, training and mentoring. This community service program encouraged the local farmers to be able to utilize the local raw materials as a source of shrimp feed, use the feed pellet machine, and packaging leading to independent feed production. The participatory training method, lectures, forum group discussions, and practices of making shrimp feed and packaging were applied. The Implementation of the Community Partnership Program of Shrimp and Fish Cultivation Groups is independently able to produce organic fish or shrimp feed for farmer’s group leading to higher productivity of aquaculture.

Engaging farmers as citizen scientists may be a cost-efficient way to answering applied research questions aimed at more sustainable land use. We used a citizen science approach with German horse farmers with a dual goal. Firstly, we tested the practicability of this approach for answering ‘real-life’ questions in variable agricultural land-use systems. Secondly, we were interested in the knowledge it can provide about locomotion of horses on pasture and the management factors influencing this behaviour. Out of 165 volunteers, we selected 40 participants to record locomotion of two horses on pasture and provide information on their horse husbandry and pasture management. We obtained complete records for three recording days per horse from 28 participants, resulting in a dataset on more individual horses than any other Global Positioning System study published in the last 30 years. Time spent walking was greatest for horses kept in box-stall stables, and walking distance decreased with increasing grazing time. This suggests that restrictions in pasture access may increase stress on grass swards through running and trampling, severely challenging sustainable pasture management. Our study, involving simple technology, clear instructions and rigorous quality assessment, demonstrates the potential of citizen science actively involving land managers in agricultural research.

Nanoencapsulation via spray cooling (also known as spray chilling and spray congealing) has been used with the aim to improve the functionality, solubility, and protection of drugs; as well as to reduce hygroscopicity; to modify taste and odor to enable oral administration; and many times to achieve a controlled release profile. It is a relatively simple technology, it does not require the use of low-cost solvents (mostly associated to toxicological risk), and it can be applied for lipid raw materials as excipients of oral pharmaceutical formulations. The objective of this work was to revise and discuss the advances of spray cooling technology, with a greater emphasis on the development of lipid micro/nanoparticles to the load of active pharmaceutical ingredients for oral administration.

Carbon membranes have high adsorption capacitiy with respect to its incredible properties such as unique structural, electronic, optoelectronic, semiconductor, mechanical, chemical and physical. Carbon nanotube (CNT) membranes because of its high permeance have been recently developed.Great attention has been currently paid to the field of fabrication methods capable of producing uniform, well-aligned and monodispersed CNT array. Current research concerns with fabrication of vertically aligned CNT membrane in order to remove heavy metal ion presents in waste water. For this purpose, CNTs are vertically grown up through the holes of anodic aluminium oxide (AAO); as a template, by chemical vapor deposition (CVD) of acetylene gas.In this work a few heavy metals such as Pb (II), Cu (II) and Cd (II) has been examined for checking the perfomance of membrane in aqueous solution. The morphological properties of the aligned CNT membrane were investigated with scanning electron microscopy (SEM). The method has simple technology, low cost, and easy reproduction.

The farming of aquatic environments is already a large-scale world enterprise involving relatively simple technology, but aquacultural production in North America is only a small part of the world total. Aquaculture is only economically rewarding where high rates of production over a long growing period can be coupled with close proximity to large markets in which there are few cheap alternative sources of protein. Much of North American aquaculture is aimed at meeting demands of recreational fishermen rather than as a way of producing food. There are many opportunities for development of aquaculture in North America and it seems reasonable to project substantial increases in production in the next two decades.Key words: aquaculture, geographical location, North America, future prospects, economics
