Abstract. Hastuti, Purnomo, Sumardi I, Daryono BS. 2019. Diversity wild banana species (Musa spp.) in Sulawesi, Indonesia. Biodiversitas 20: 824-832. Indonesia is known as one of the centers of banana diversity in the world. There are 70 species of wild banana in the genus of Musa, 12 of them it was found in Indonesia. Sulawesi was located in the Wallace Line, which is a meeting between the Sunda and Sahul exposures, and has many endemic species, some of which are wild banana species. However, studies on wild banana in Sulawesi are still limited. This study focuses on species of wild bananas found in Sulawesi. Purposive sampling was used to select banana example from wild, cultivated area, residential areas and research garden. Observation was carried out in the field as well as using a collection herbarium and living specimens. The observation was done by observing the characteristics of the sample according to the guidance on Descriptor for Banana. Identification was done by matching the sample with herbarium and relevant references. The results showed that there were four species of wild bananas found on the island of Sulawesi. These are Musa balbisiana Colla, Musa acuminata Colla var. zebrina (v.Houtte) Nasution, Musa acuminata Colla var. banksii (F.Muell.) N.W Simmonds, Musa acuminata Colla var. lutraensis, Musa acuminata Colla var. sigiensis, Musa acuminata Colla ssp. microcarpa Becc., Musa borneensis Becc. and Musa textilis Nee. Four wild banana accessions had never been reported before. These were Musa acuminata var. zebrina, Musa acuminata var. lutraensis, Musa acuminata var. siginenesis and Musa borneensis.

Representation Of Knowledge

The banana, the world's most widely produced and commercialized fruit, is grown in all tropical regions of the world, being strongly present in local businesses and subsistence crops serving as an important source of nutrients for the poorest populations. In the state of Rio de Janeiro it is commonly found in hillside and difficult access areas, where most other crops would not be able to settle and, because of this, is grown with inadequate management or insufficient, resulting in low productivity in the areas of Rio de Janeiro. The objective of the present work is to carry out a survey of smallholder information from the Vale do Rio Sahy Association in Mangaratiba, RJ, to enable the representation of knowledge in this domain. From the data collected in this research, it was realized that producers have been engaged in this activity for a long time. However, it was found that the knowledge used to production is extremely tacit, without systematization. The variety of banana species (Musa spp.) grown in the production area of the association's small farmers. The knowledge transfer process knowledge to the knowledge base of an expert system is called knowledge acquisition, where it involves extract all the knowledge from the source of the specialists to systematically represent in a coded form the domain information in an appropriate medium. It was observed, even if preliminarily, that this knowledge are not represented in a database for consultation. Thus, there is a need to define human expertise or producers capable of representing in a technological way data that can be conveniently accessed for Problem solving. In view of the evidence presented in the research, the use of representation of human knowledge (small local producers) to feed and train the system according to the domain presented. Thus, enabling the prototype to help understand climate and soil variables and collaborate in decision making.

The fact that groundwater is the only source of drinking water in Yemen mandates strict monitoring of its quality. The aim of this study was to measure the levels of fluoride in the groundwater resources of Dhamar city. Dhamar city is the capital of Dhamar governorate located in the central plateau of Yemen. For this purpose, fluoride content in the groundwater from 16 wells located around Dhamar city was measured. The results showed that 75% of the investigated wells contain fluoride at or below the permissible level set by the World Health Organization (0.5 – 1.5 mg/L), whereas 25% of the wells have relatively higher fluoride concentrations (1.59 – 184 mg/L). The high levels of fluoride have been attributed to the anthropogenic activities in the residential areas near the contaminated wells. Interestingly, some wells contain very low fluoride concentrations (0.30 – 0.50 mg/L).  Data were statistically treated using the principal component analysis (PCA) method to investigate any possible correlations between various factors. PCA shows a high correlation between well depth and its content of fluoride. On the other hand, health problems dominating in the study area necessitate further studies to investigate any correlation with imbalanced fluoride intake.

The application of industry 4.0 has been doing in many countries in the world today even some developed countries have headed to industry 5.0, nevertheless in Indonesia there are still many companies that have not implemented industry 4.0. This research aims to find out the extent of the implementation of industry 4.0 in Indonesia, especially the industry located on the island of Java.The industry 4.0 aspects as a benchmark of differentiator from previous industrial developments is worth scrutinized to know its application levels in the service and manufacturing industries. Although many industries still combine their operating system between the 4.0 industry and conventional operating systems. The populations are the services and manufacturing companies. The data was obtained by using a questionnaire distributed online to respondents with a purposive sampling method. The data was grouped according to The level of implementation and is centered. The calculation and percentage results demonstrate that the level of implementation of the 4.0 industry with a technology base in service companies and manufacturing companies are at a managed level. It illustrates that the companies being researched have not been fully on the demands of the 4.0 industry.

This chapter highlights the geographical aspects of health disparities in Japan at different levels, from the 47 prefectures nationally to the neighbourhood level. In the post-war period, Japan has successfully attained the longest life expectancy in the world. At the same time, it has substantially reduced geographical disparities among the prefectures. This indicates that reducing such disparities in living standards may also be related to improving the health of a country’s entire population. However, disparities of health have appeared among populations living in socially segmented areas in large neighbourhoods of metropolitan regions. Such neighbourhood-scale disparities in health are associated with a number of environmental characteristics of Japanese neighbourhoods reflecting socioeconomic segregation and development histories of residential areas. In the era of a super-aging society that contains the threat of re-widening social inequalities, Japan faces challenges to build health-supportive environments for tackling multi-scale disparities.

Two types of anomalous erosive wear, designated “Wear” and “Groove”, were found in the molar teeth of adult babirusa (genus Babyrousa Perry, 1811) species from Buru or the Sula Islands and Sulawesi, Indonesia. A survey of 590 specimens of babirusa crania and mandibles from international museums and private collections revealed their presence in 20 of 187 specimens from Buru or the Sula Islands, in 99 of 391 specimens from Sulawesi, and in 4 of 31 subfossil specimens from South Sulawesi. “N_Wear” comprised a discrete indentation or almost circular erosion of the enamel and underlying dentine in a molar tooth; “W_Wear” comprised tooth indentations of irregular shape larger than 7 mm × 7 mm in size; “E_Wear” comprised extensive tooth indentation. “Wear” anomalies were found on 10% of specimens from Buru or the Sula Islands and on 17% of all Sulawesi crania and mandibles. It was hypothesised that tooth grinding of the abrasive seeds of the wild banana (Musa balbisiana Colla) initiated this anomaly. Groove was a deep, oval-shaped cleft cut into the enamel and dentine between two molar teeth. Groove anomalies were evident in 3% of Buru or the Sula Islands specimens and in 12% of all Sulawesi specimens. No conclusion was reached regarding the initiator of the Groove anomaly.
