Abstract

Textile dyes are divided into two types, natural dyes and synthetic dyes. Natural dyes commonly made from extraction. Extraction is a process in which one or more components are separated selectively from a liquid or solid mixture, the feed, by means of a liquid immiscible solvent. Extraction can be classified into two group, liquid extraction and solid-liquid extraction. Solvents that are usually used in the extraction of natural dyes are aquades and ethanol. The purpose of this research was to determine the chemical structure, especially tannin in natural dyes from mangrove species Rhizophora stylosa through several samples testing natural dyes. Rhizophora stylosa that have been extracted and evaporated will conducted several tests to obtain chemical structures in natural dyes and yield of tannin in natural dyes. Tests carried out include testing FT-IR, and HPLC. Based on FT-IR analysis, the extraction of Rhizophora stylosa containing tannin indicated by the presence of hydroxyl (O-H) in the area of 3385.36 cm-1, aromatic (C-H) in the area of 1365.53 cm-1, carbonyl (C=O) in the area 1646.36 cm-1, esters (C-O) in the area 1217.30 cm-1. While tannin content obtained from the analysis of HPLC were 6.087 ppm.

Abstract

Linear alkylbenzene sulfonate (LAS) belongs to a class of surfactants claimed as an environmentally friendly detergent due to its biodegradability. However, the disposal of LAS waste into the waters without prior treatment causes a risk to the ecosystem. These experiments aimed to study the effects of commercial inoculum size EM-4 on the aerobic decomposition process of LAS in a well-shaped bioreactor. These experiments of LAS decomposition were carried out in a batch system aerated by 2.5 L/min for the low and high initial LAS concentrations. The effects of inoculum acclimation were also investigated for the high LAS concentration. The effects of inoculum size were explored at sizes ranging from 5 to 20% v/v, and samples were taken on a regular basis for residual LAS assessment. The first-order kinetic model gave the best fit to the rate of LAS decomposition, with the highest rate coefficient of 10.44 x 10-2 hour-1. This was achieved by using a 20% v/v inoculum for the initial low concentration of LAS, resulting in the highest decomposition efficiency of 89.4% after 24 hours of incubation. The decomposition rate was slower at the high LAS concentrations than at the low concentrations. The inoculum acclimation increased the decomposition rate for the high LAS concentrations. The results of this study show great potential for the bioremediation of LAS detergent waste using commercial inoculum in a well-shaped batch bioreactor.

Abstract

The availability of ruminant feed in terms of amount and nutritional adequacy is a common problem during the dry season. This condition is worst at the peak of the dry season (July - October) such as that faced by the Kelompok Tani Rukun Binantu of Rejosari in Bantul Regency - Yogyakarta. Pre-survey shows that the cost of feed in the dry season is uncompetitive to the price of cattle. This problem was solved by Program Kemitraan Masyarakat (PKM – UNS) 2020 with workshop in cattle feed preservation using silage and fermentation techniques. The silage technique is used in conventional-local forage, while the fermentation technique is aimed at preserving low-nutrient animal feed as well as improving digestibility and nutritional adequacy of the feed. Product’s monitoring and evaluation are carried out after 7 days for fermentation technique and 21 days for silage technique. The program is success in solving of Mitra’s problems and it is also one of Tri Dharma Perguruan Tinggi in technology transfer for rural communities.

Abstract

In general, natural dyes for textile materials are obtained from extracts part of the plants such as roots, wood, leaves, seeds, and flower. Textile industry especially batik craftsman, have known many plants that can dye textile materials, such as indigo (indigofera), soga tingi bark (Ceriops tagal), tegeran wood (Cudraina javanensis), turmeric (Curcuma), tea (The), noni root (Morinda citrifelia), soga jambal bark (Pelthophorum ferruginum), kesumba (Bixa orelana), and guava leaf (Psidiumguajava). Soga tingi bark chosen because it can produce tannins which can be used as natural dyes. The purpose of this research was to obtained tannin content in soga tingi bark as qualitatively and quantitatively. The analysis carried out is FTIR and HPLC method. FTIR analysis carried out to determine of the compounds contained in the soga tingi bark extraction. Based on FTIR analysis it can be seen that there are O-H and N-H group in the wavenumber 3375,13 cm-1. C=O bond at wavenumber 1739,16 cm-1. C=C bond at wavenumber 1624,31 cm-1. C-H bond at wavenumbers 2970,72 cm-1, 1456,39 cm-1, and 1365,74 cm-1. NO2 bond at wavenumber 1365,74 cm-1. C-N bond at wavenumbers 1228,69 cm-1 and 1217,34 cm-1.

Abstract

ABSTRACT. The growth of the packaged beverages market in Indonesia is overgrowing. One sector of packaged beverages is carbonated beverages and bottled water. The main problem with packaged beverages containing dissolved gases is maintaining product quality during shelf life. Packaging materials and packaging lids cause a decrease in dissolved gas levels in beverages. Therefore, this study aims to analyze leaks in polyethylene terephthalate and glass bottles so that can use them to estimate the shelf life of the product. This study uses water, 3 types of glass bottles, and 1 type of plastic bottle. Bottles filled with water with various filling volumes of 40%v/v, 60%v/v, and 80%v/v were then analyzed for bottle leakage for 8 days. The results showed that effectively used a glass bottle with a volume of 250mL filled with more than 80%v/v, this was because it had the least leakage rate compared to others. In addition, this bottle has an attractive visual, easy labeling, and the size is not too large (ergonomic).Keywords: Glass bottle, plastic bottle, leakage test, shelf life

Abstract

The effect of molasses addition as a binder in the manufacturing of cow dung bio-pellets on their characteristics and combustion kinetics have been studied. The bio-pellets characterization included the physical and mechanical properties as well as the proximate analysis and calorific values. Thermogravimetric analysis (TGA) was carried out using a macro-TGA apparatus under a non-isothermal conditions and an oxidative atmosphere to study the thermal decomposition characteristics. Then, the first order Coast and Redfern method was used to determined the kinetic parameters of bio-pellets combustion. It was found that the ash content of bio-pellets were tended to decreased, while the volatile matter and fixed carbon were tended to increase with the addition of molasses. Nevertheless, the density, the axial compressive strength and the calorific values of bindered bio-pellets were decreased due to the higher amounts of water in the raw mixtures. Thermogravimetric analysis provided an information that the combustions of cow dung bio-pellets took place in three stages of decompositions The bindered bio-pellet began to decompose at lower temperatures than the binderless bio-pellet with a higher weight loss percentage. According to the comprehensive combustion characteristic index (S), the combustion performance of both binderless and bindered bio-pellets were similar. The addition of molasses as a binder tended to reduce the ignition temperature and activation energy for all stages of bio-pellets combustion. Keywords:Bio-pellet, Characterization, Cow Dung, Combustion Kinetics, Molasses

Abstract

The territory of Indonesia consists of various types of graphic conditions with various prosperities that arevery potential to be developed. One of them is the potential of biopharmaceuticals products in Pacitan Regency, precisely in Tahunan Baru Village, Tegalombo District. Packaging and marketing ofbiopharmaceutical products is still a basic problem that will be solved through the Sebelas Maret University's Student Community Program or 'Kuliah Kerja Nyata' (KKN) for the July-August 2022 period.Initial surveys show that packaging has not yet become an important aspect to attract market interest. Crucial information related to the product has not been included in the packaging design, such as product identity, expiration date, and composition. From the marketing aspect, product sales are still in the conventional way. To support the optimization of biopharmaceuticals products in terms of packaging and marketing, the programs are carried out in the form of human resource development, mapping and digitising MSMEs, ginger candy, rebranding, labelling, and digital marketing training. Implementation of activities using face-to-face methods both individually and in groups in the form of socialisation, discussion and demonstration or direct practice.
