<p>Abstract<br />Central Java is popular for soybean tofu and one of its diversification product is ‘tahu bakso’which<br />is very famous in Central Java especially Semarang. Utilisation of nile fish meat can support fish protein<br />intake by community as well as for promoting local protein resource. The aims of this study was to observe<br />the effect of different concentration of fish meat on physical, chemical and sensory characteristic of ‘tahu<br />bakso’. The parameters evaluated include texture (hardness, deformation, gel strength), proximate (protein,<br />fat, carbohydrate, ash and water), and sensory (hedonic test) of the product resulted. This study used<br />experimental laboratory by using Completely Randomised Design with Anova (p&lt;0,05). The treatments<br />covers: different concentration of fish meat (30%, 40% and 50%). Treatment with highest hardness and<br />gel strength was performed by 30% concentration with the value of 530.88 g.cm. Whereas treatment 40%<br />concentration has highest deformation of 23.47 mm, and has no significant different to 50% concentration.<br />Based on analysis of variance, different concentration of fish meat gave significant effect on characteristic<br />of proximate especially on protein and fat (p&lt;0.05) but has no significant effect on water and ash content<br />(p&gt;0.05). Different concentration of fish meat has no significant effect on hedonic of ‘tahu bakso’ resulted.</p><p>Overall ‘tahu bakso’ made from nile meat with 50% concentration is considered to be the most preferred by<br />panelist, but the overall value has no significant different to 40% concentration. Therefore, it is concluded<br />that concentration 40% of fish meat is considered as the best treatment for producing ‘tahu bakso’ with<br />respect to texture, nutrition, sensory attributes.<br /><br /></p>

Abstract. Rimadiyani W, Krisanti M, Sulistiono. 2019. Macrozoobenthos community structure in the Western Segara Anakan Lagoon, Central Java, Indonesia. Biodiversitas 20: 1588-1596. Anthropogenic activity along the river and around the coastal area will potentially generate waste as it can cause the decline of water quality and affect the lives of macrozoobenthos. This study aimed to study macrozoobenthos community structure in western Segara Anakan Lagoon and its relationship with water physical-chemical quality. The study was conducted from June to November 2016, at six stations of the lagoon. Macrozoobenthos obtained during the study consisted of four phyla (Annelida, Mollusca, Crustacea, and Sipuncula), six classes, and 33 genera. The highest abundance of macrozoobenthos was at Station 6 (193 ind./m2) dominated by Malacostraca and the lowest abundance of macrozoobenthos was at Station 1 (13 ind./m2) dominated by Bivalvia. Diversity, Evenness and dominance indices of the macrozoobenthos were 0.0-2.0, 0-0.8, and 0.4-1.0, respectively, indicating a medium ecologically stressed. Mud substrate condition with high percentage of organic material affected the community structure of the macrozoobenthos expressed by a high density and diversity, but low dominance indices.

High Diversity

Diatom communities in the lake have an advantage of environmental assessment and paleo reconstruction study, due to the ability of diatom preserved in the sediment. There are only limited studies about taxonomy, ecology, and diversity of diatom flora in tropical areas, especially Indonesia. The main objective of the research is to describe the structure of benthic diatom communities in Pengilon Lake, together with physical chemical variables. Sediment samples were collected at an altitude of more than 2,000 msal habitats with pH around 5.40-6.86. A total of 83 diatom species identified as belonging to 16 families. The diversity index ranges from about 2.25 to 3.01 indicated the ecosystem that naturally stable with none diatom dominant. The most abundant genera were Eunotia with high diversity around 14 taxa. The composition of Eunotia assemblages was different among habitat and season variation. Eunotia has a wide tolerance of pH because of its ability to survive in an area with an acidic environment and circumneutral water. The most dominance diatom species in Pengilon Lake were Eunotia paludosa (Grunow) 39.2%, Nitzschia frustulum (Kutzing) 28.1%, Pinnularia viridis (Krammer & Lange-Bertalot) and Pinnularia divergentissima (Grunow) 24.6%.

Transmission Electron

Electron microscopic methods have been applied increasingly during the past fifteen years, to problems in structural molecular biology. Used in conjunction with physical chemical methods and/or Fourier methods of analysis, they constitute powerful tools for determining sizes, shapes and modes of aggregation of biopolymers with molecular weights greater than 50, 000. However, the application of the e.m. to the determination of very fine structure approaching the limit of instrumental resolving power in biological systems has not been productive, due to various difficulties such as the destructive effects of dehydration, damage to the specimen by the electron beam, and lack of adequate and specific contrast. One of the most satisfactory methods for contrasting individual macromolecules involves the deposition of heavy metal vapor upon the specimen. We have investigated this process, and present here what we believe to be the more important considerations for optimizing it. Results of the application of these methods to several biological systems including muscle proteins, fibrinogen, ribosomes and chromatin will be discussed.

Opening Up

Despite the considerable advances in molecular biology over the past several decades, the nature of the physical–chemical process by which inanimate matter become transformed into simplest life remains elusive. In this review, we describe recent advances in a relatively new area of chemistry, systems chemistry, which attempts to uncover the physical–chemical principles underlying that remarkable transformation. A significant development has been the discovery that within the space of chemical potentiality there exists a largely unexplored kinetic domain which could be termed dynamic kinetic chemistry. Our analysis suggests that all biological systems and associated sub-systems belong to this distinct domain, thereby facilitating the placement of biological systems within a coherent physical/chemical framework. That discovery offers new insights into the origin of life process, as well as opening the door toward the preparation of active materials able to self-heal, adapt to environmental changes, even communicate, mimicking what transpires routinely in the biological world. The road to simplest proto-life appears to be opening up.

This business is one of famous business in Yogyakarta, we will find rows of pavement vendors selling market munchies. The students and tourists are their main target customers. Market munchies enterprise is part of small and medium enterprises SMEs as livelihood activities. SMEs has an important role in economic growth of Indonesia. Therefore, it is very important to develop and strengthen the micro enterprise empowerment. Micro enterprise empowerment is one of strategy to reduce the poverty rate in Indonesia. Major challenger in implement this program are that micro entrepreneurs are conventional and have satisfied with their revenue. It is very important to develop a comprehensive and sustainable micro enterprise empowerment which consist of strengthen the quality of human resources, maximize the government’s roles, empower the enterprise capital and strengthen the partnership and autonomous. Micro enterprise autonomy will contribute to the economic and investment climate. This will lead to establish an accountable enterprise both for the micro enterprise and customers which at the end will strengthen the development of the micro enterprise in Yogyakarta.Keyword: micro entreprise, human resources, government roles, capital, partnership and autonomous.
