Abstract

Granulation is a process of monoparticle attachment with a particular mechanism to form a bigger and compact particle which is called granule. Granulation application has been used on many industries like pharmacy and agriculture industries. Research about granulation has been done continuously to get predictive models for various cases. The model which is only applicable to the specific material used in this research is expected to be useful to optimize the perfomances of the granulator in the industries. This research aims to develop the kinetics model of granule size distribution of cassava flour and its connection to granulation time by varying the mass of tapioca starch as the binder in rotary drum granulator. 2 grams of Cassava flour and tapioca starch were mixed in the rotary drum granulator and then water was sprayed during the granulation process. The duration of granulation were 5, 10, 15, 20, and 25 minutes. The variations of mass of the binder used in this research were 1, 1,5, and 2 gram. The granules were dried in the oven at 80°C until 30 minutes, and afterwards the granules were screened through various screen layers with different mesh size. The results of this research show that binder mass variations do not influence the layering rate of granule, and the increase of binder mass will decrease the birth rate.

Abstract

Separation and capture of carbon dioxide (CO2) has become a very hot topic of discussion recently. The increasing amount of carbon dioxide in the environment makes environmental pollution very significant. Membrane technology is one of the alternative carbon separation processes that are increasingly in demand, because membrane technology provides excellent advantages in terms of energy requirements used, capital investment invested, and ease of operating equipment compared to other processes. Many membrane constituent materials can be used to be the basic material for making membranes, including polymeric materials. This review discusses the various polymeric materials that can be used as basic materials for gas membranes in terms of plasticization, constituent components, flexibility, and mechanical strength. It also provides an understanding of alternatives to improve the properties of polymer-based membranes.

Abstract

Bambara groundnut has potential to be expanded in dry land and cover crops. The aim of this research is to determine the effect of shade and type of accession on the growth and yield of Bambara bean plants. The research was conducted in Dukuh Tanjung, Umbulmartani Village, Kec. Ngemplak, Kab. Sleman during the dry season. The design used was a Randomized Complete Block Split-Plot Design with two factors. The main factor is shade and no shade treatment, while the subsidiary factor is the type of accession which consists of 6 local accessions. The results showed that (1) the Sumedang Brown and Bogor accessions had the best vegetative growth based on the variables of plant height and number of trifoliate leaves at 5 WAP. (2) The Sumedang Brown and Bogor accessions had the fastest flowering time. (3) The Madura, Gresik and Jampang Tengah Sukabumi accessions had the highest number of pods. (4) 50% shade treatment can reduce pod production in the Jampang Tengah Sukabumi and Gresik accessions.
