Abstract

Latex is a white, milky liquid that comes out of injured plants from the Hevea brasiliensi plant. Heveabrasiliensi latex can be processed into rubber because it has good properties which contain rubber particlesin the form of poly isopropene hydrocarbons which are the main components of rubber. In this study, latexcoagulation used an organic coagulant as a latex coagulant, namely extract from pineapple fruit and liquidsmoke from rubber wood, oil palm midrib, coconut shell. The results of coagulation were measured by thequality of dry rubber content (KKK) and PRI. Supported by secondary data, namely literature taken fromjournals and browsing on the internet. The results showed that the best coagulant material was produced bypineapple extract 80%, liquid smoke of coconut shell with a pH of 4.1, liquid smoke of palm fronds with a pHof 3.2, and liquid smoke of rubber wood with a pH of 2.6.

Abstract

One of the environmental problems in Indonesia is plastic waste which is made from synthetic materials. This synthetic plastic waste is very difficult to decompose in the soil and takes 300-500 years to completely decompose. Therefore, bioplastic is an alternative to this problem. The purpose of this journal review is to calculate the cellulose potential of empty bunches (EFB) and oil palm midribs (PKS) through several processes, namely the delignification process and the bleaching process. ) 31.7%. So it can be said that empty fruit bunch cellulose (TKKS) and palm fronds (PKS) have enormous potential to meet the needs of bioplastic raw materials.

Abstract

Oil palm trunks can produce quite a lot of sap water, which is approximately 10 per day for 1 month for 1 oil palm tree that is uprooted, currently, there is not much optimal processing of palm oil with an economical selling price, for this reason, it is necessary to develop functional foods. This study aims to determine whether palm sap can be used in the manufacture of symbiotic beverage products with optimum chemical, microbiological and organoleptic qualities. The study was arranged using a non-factorial Completely Randomized Design (CRD) method with 3 treatments of incubation time, namely 12 hours, 24 hours, and 36 hours with each treatment using 6 replications so that 18 experiments were carried out. The best treatment by SNI 2981:2009 was obtained at an incubation time of 24 hours, namely with a pH of 5.2, water content is 82.50%, total dissolved solids is 17.33%, the lactic acid content is 0.81%, a total lactic acid bacteria of 2.8 x 108 and produces a minimum dense texture with sufficient acidity. The organoleptic aspect of taste and aroma at 24 hours of incubation time was favored or acceptable to consumers with a taste score of 3.3b and aroma of 3.3ab (scale 1-5) in the hedonic rating test. Meanwhile, at 36 hours of incubation, consumers did not like it with a taste score of 2.2a and aroma of 2.1a. This is because the longer the fermentation time can increase the acidity of the product which causes the distinctive taste and aroma of palm sap to increase.
