Massive engagement with the meaningful learning in the topic of nature may affect student emotional feeling and attitude towards nature. This research aims to reveal student’s biophilia or attitude towards the nature and to provide an analytical teaching and learning setting in addressing the challenge learning outcome in the Education for Sustainable Development/EfSD. Student participants were observed using the questionnaire measuring their feeling towards nature or biophilia. The data were then analysed descriptively using simple descriptive analysis and scrutinized in term some possibilities of meaningful teaching and learning efforts using theoretical frameworks and propositions. The observed student’ biophilia is considered low, showing unsatisfying level of attitude towards nature among participants. Teaching and learning design engaging meaningful educational processes may be of alternatives in enhancing student’s better attitude towards nature. The Emome enriched by an active learning method is assumed to be able to address the challenge of biophilia reinforcement since its power in smoothing student’s feeling towards biodiversity, environment and nature.

BOD value is a test parameter in a laboratory that depends on time and temperature. The reaction rate of BOD value for time is defined as the deoxygenation coefficient (k) which depends on the concentration of organic matter in the sample and the relation described in the Streeter-Phelps equation, kT = k20 θ(T-20). In the equation, the value of the temperature coefficient must be determined so that the required incubation time can be calculated for the incubation temperature that is different from the standard method. Various literatures mention the value of the temperature coefficient in the range of numbers 1.03 - 1.09. If there are certain wastewater with low organic concentration matter the temperature coefficient is unknown, the number 1.047 will be used at the testing temperature in the laboratory, 27 - 29 °C. This study aims to analyze whether the coefficient value can be applied to specific wastewater such as faecal sludge waste in various concentration, low to high. The thing to do is to compare the determination of the standard method BOD value by determining BOD at another temperature in the incubation time span estimated using the temperature coefficient value of 1.047. It will be known whether the determination of BOD value can be done by incubation at laboratory temperature and shorter time will have a higher deoxynegation coefficient value when compared to the standard method at temperature 20 °C.BOD value is a test parameter in a laboratory that depends on time and temperature.

In addition to producing palm oil (CPO) and Palm kernel Oil (PKO), palm oil agroindustry also produces quite a lot of biomass solid waste residues. One of them is empty fruit bunches (EFB) which have not been optimally utilized and accumulated in the area around the factory location. Currently, the conventional EFB utilization has only been limited to mulch material and fertilizers used in oil palm plantations. This biomass material has enormous potential in producing renewable energy, chemical products, etc. Cumulatively, the product has high added value. Considering that the volume of EFB has the largest proportion in oil palm plantation waste, which is reaching (20-23%) of fresh fruit (FFB), it is necessary to study the availability of EFB in supplying raw materials for bioenergy products. In this study, data collection and retrieval are taken from palm oil companies in Kutai Kartanegara, East Kalimantan. The problems that have so far been unknown are the potential availability of raw materials in maintaining the fulfilment of the need to produce bioenergy sustainably. Therefore, this study is intended to predict the needs and amount of raw material supply. The System Dynamic Methodology is used as a tool in predicting the availability and long term needs of raw materials and creating scenarios in the face of limitations in the availability of sustainable raw materials. The model is built on three main sub-models, namely the plantation area, the biomass availability, and the conventional utilization sub-model. The study show that an increase in harvested area will certainly be followed by additional FFB harvests and the resulting waste stock including the solid waste of palm oil empty bunches. The rate of empty bunches will decrease along with the crop productivity which also decreases according to the plant age. The scenario proposed to adjust the condition of raw materials is replanting. Planting of new plants will be carried out from the 19th year of the simulation, at the age of 23 years, which is expected to be harvested in the 22 simulation years. The second scenario is the utilization of another biomass as a source of the biomass. Besides EFB, there are other biomass which have the potential to be used as bioenergy, namely frond. By combining some of the biomass, greater availability of biomass will be obtained. The scenario of combining with other biomass is the most suitable (frond biomass) because of its similar characteristics to EFB and the stability of its availability.

The industrial world has entered the era of industrial revolution 4.0. In this era, there is an urgent data requirement from the community to support service policies. Because of that, Surabaya Government made Media Center Surabaya. This media is used to accommodate all the aspiration of Surabaya citizen. To access this media, a citizen can use Twitter. The topic which is discussed in Twitter is important information that we need to know. The information can be used to improve the performance of Surabaya Government services. Twitter data is a text data that consists of thousands of variables. Text mining is frequently used to analyze this kind of data, including topic modeling and sentiment analysis. This study would work on topic modeling focused on the algorithm employing Latent Dirichlet Allocation (LDA) and Latent Semantic Analysis (LSA). The evaluation of the algorithm performance uses the topic coherence. As unstructured data, the Twitter data need preprocessing before the analysis. The stages of preprocessing include cleansing, stemming, and stop words. The advantages of LSA are fast and easy to implement. LSA, on the other hand, doesn’t consider the relationship between documents in the corpus, while LDA does. This study shows that LDA gives a better result than LSA.

The topic which is discussed in Twitter is important information that we need to know. The information can be used to improve the performance of Surabaya Government services. Twitter data is a text data that consists of thousands of variables. Text mining is frequently used to analyze this kind of data, including topic modeling and sentiment analysis. This study would work on topic modeling focused on the algorithm employing Latent Dirichlet Allocation (LDA) and Latent Semantic Analysis (LSA). The evaluation of the algorithm performance uses the topic coherence. As unstructured data, the Twitter data need preprocessing before the analysis. The stages of preprocessing include cleansing, stemming, and stop words. The advantages of LSA are fast and easy to implement. LSA, on the other hand, doesn’t consider the relationship between documents in the corpus, while LDA does. This study shows that LDA gives a better result than LSA.","PeriodicalId":246056,"journal":{"name":"THE 2ND INTERNATIONAL CONFERENCE ON SCIENCE, MATHEMATICS, ENVIRONMENT, AND EDUCATION","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122072770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Environmental problems and natural damage are significant problems in the 21st century learning. Critical thinking skills about environmental (Eco Critical thinking skills) are important for prospective teacher elementary school. Research to improve critical skills about the environment (eco critical thinking skills) in prospective teachers, requires a variety of instruments that are able to measure according to what will be measured. The purpose of the study was to examine the validity of the instrument by looking at the suitability of the questions (item fit) and student’s ability on the politomical instrument of environmental education in prospective elementary school teachers. Instrument analysis used in the study using the Rasch model. The results showed Mean Square Outfit, Z-Standart Outfit and Outfit Point Measure Correlation from the item had the suitability of the problem to be able to measure according to the model being measured. This shows that the instrument is feasible to be used in the measurement.Environmental problems and natural damage are significant problems in the 21st century learning.
