Utilization of agricultural waste toward sustainability has increase a value-added product from a natural resources nowadays. Metroxylan sagu pith waste (MSPW) is a residue from starch extraction process. This research aim to investigate the potential of MSPW as a biodegradable fillers to replace sago starch in Natural Rubber (NR) latex films. The MSPW flour is characterized and compared with sago starch. Results shown MSPW has almost similar properties with sago starch with high content of starch (60%) and moisture (80%). Spectra of MSPW and Sago Starch (SS) are very closed to one another due to the similarity of functional groups. SS has granular shape while MSPW has irregular shape under SEM analysis. The addition of MSPW shown slightly lower tensile properties and tear strength as compared to SS but still within the acceptable value. Thus, MSPW has high potiential to replace SS as biodegradable fillers in NR latex films.

Production is an activity to convert inputs into outputs through the transformation process. Input in the form of man, money, method, material, machine. While the output is in the form of goods or services. The purpose of production in general is to meet individual needs. There are several factors that influence production namely land and all economic potential that is processed and cannot be separated from the production process, labor is directly related to the demands of property rights through production, and capital, management and technology. In production there are various types of production, namely production which is intermittent and continuous. The production, if viewed from an Islamic perspective, it must fulfill the following principles. First, produce in a halal circle. Second, managing natural resources in production is interpreted as the process of creating wealth by utilizing natural resources must rely on the vision of the creation of this nature and along with the vision of human creation, namely as a blessing for all nature. Third, the Caliph on the earth is not only based on the activity of producing the usefulness of an item but work is done with the motive of benefiting to seek the pleasure of Allah SWT.

Biomass Loss

One of the major advantages of biofuel over fossil fuel is that it is environmentally friendly but unfortunately most of the chemicals used in the pretreatment of lignocelluloses biomass to produce biofuel can cause adverse effects to the environment. In this study, ionic liquid was used for the pretreatment of cocoa waste. Its effectiveness in the treatment process was compared to the alkalis and acids used in the conventional pretreatment media. The effectiveness of pretreatment using ionic liquid, H2SO4 and NaOH was based on the reduction of biomass, production of reducing sugar and also bioethanol. Ionic liquid pretreatment was found to show minimal biomass loss of only 31% after pretreatment compared to H2SO4 and NaOH which showed loss of 61% and 79% respectively. The untreated biomass has 10% amount of cellulose but upon pretreatment with ionic liquid, H2SO4 and NaOH, significant amount of cellulose was detected compared to NaOH which produced only 7% of cellulose. Two types of yeasts were also isolated from Malaysian local fermented food, the tapai ubi which were tested for the abilities to ferment the reducing sugar produced. Using the DNS method for determining reducing sugar, ionic liquid pretreatment was shown to produce 6.3×10–2g/L of reducing sugar while the untreated, H2SO4 and NaOH pretreatment produced 2.87×10–2g/L, 7.4×10–2g/L and 3.37×10–2g/L respectively at the end of 24 hours of incubation. Bioethanol produced during the fermentation was analysed using gas chromatography. Ionic liquid produced a total of 7.885g/L, H2SO4 produced 7.911g/L NaOH produced 6.824g/L and untreated cocoa waste produced 5.116g/L of ethanol at the end of 24 hours incubation.

This study was based on the production of bioethanol as an alternative source of fuel using rice and millet husks. Proximate, elemental and thermogravimetric analysis (TGA) were conducted of the biomass. The proximate analysis revealed that millet husk had the highest moisture content of 26.67±0.58% when compared with rice husk 8.17±0.29%. The TGA of rice husk had a high endset temperature of 355.510C and a weight loss of -48.23%, millet husk had low endset temperature of 349.210C and a weight loss of -44.25%. When thirty grams (30g) of the substrates was used, rice husk revealed the highest reducing sugar content of 2.59±1.24mol/dm3 when compared to millet husk that had 1.63±0.68 mol/dm3. Rice husk indicated low yield after 7 days of fermentation period but showed a significantly high yield in the volume of ethanol produced 68.67±17.69g/l and millet husk had a yield of 79.80±0.93g/l. This indicated that both rice and millet husks were potent for bioethanol production with millet husk having the highest yield.

The article is devoted to the development of methodological approaches to the use of unique natural resources (characteristics) of territories that are capable of being embodied in the consumer properties of food products produced at enterprises located in these territories. The development and production of such goods creates real prerequisites for the formation of a reputation, both of enterprises themselves and of the territories (regions) where they are located. Based on the reputation formed due to the unique natural characteristics of the area, it is recommended to develop trademarks, create regional product brands with the aim of using them in promoting goods with unique consumer properties to other regional markets, including foreign ones. The conditions and rules of registration of the name of the place of production of goods, the reflection of the toponym in the brand name are described; an overview of regional Altai product brands is presented, including the unique natural properties of the area in their consumer properties. The provision that the most acceptable for the initial presentation of Altai in other regional markets is Altai honey. As the main form of promoting Altai honey to other regional markets, it is proposed to use value-added chains. It substantiates the provision that regional product brands promoted to other regional markets, including foreign ones, contribute to the formation and development of the image of the territory, in this case, the Altai Territory. The material presented in the article can be used in the development of specific methodological proposals for solving the problems of the development of territories and enterprises located on them.
