Abstract
This study intended to develop the entrepreneurial characters of UNNES Chemistry students through the implementation of Natural Product learning integrated with Ethnoscience and STEM (Ethno-STEM). This research is a descriptive-qualitative study subjected to Chemistry education students who joined the Natural Products and Chemical Entrepreneurship course. The research subjects were introduced to the project-based learning integrated with Ethno-STEM concerning concepts related to terpenes, steroids, flavonoids, and alkaloids; also, the introduction of natural chemical isolation and distillation processes both in the community and laboratory. The students were assigned a project of chemical batik production, i.e., batik with chemical structure patterns followed by evaluation and assessment. There were six best batik designs proposed to one of the traditional batik centres named “Zie” to be printed by using batik printing machine. These designs are said to be worthy of production; in other words, they are valued economically. The research results indicated that the Natural Product learning integrated with Ethno-STEM was able to well develop the students- mastery concept of chemistry, creative and innovative thinking, perseverance, and conservation of national culture

Abstract
Gunungkidul sebagian besar kawasan administrasinya tertutup karst, dimana cadangan air tanah yang sangat besar tersimpan di bawah permukaan sebagai sungai bawah tanah. Saat musim kemarau penduduk sulit mengakses sumberdaya air di bawah permukaan tanah, sehingga penduduk menggunakan sumberdaya air permukaan yang ada di telaga atau di dalam goa meskipun jumlahnya terbatas dan kualitasnya belum teruji. Pengolahan air menggunakan filter keramik mampu menjadi solusi. Filter dibuat dengan teknik dan bahan lokal Kasongan, Bantul, Daerah Istimewa Yogyakarta. Filter pertama menggunakan komposisi lokal Kasongan yaitu tanah liat dan pasir dan filter kedua dengan komposisi 80% (tanah liat dan pasir) 20% (serbuk kayu) serta pelapisan dengan larutan perak nitrat. Pengujian sampel air menggunakan empat parameter yaitu: kekeruhan, kesadahan, Total Coliform, dan E.coli dan dilakukan di lab BBTKLPP (Balai Besar Teknik Kesehatan Lingkungan dan Pengendalian Penyakit) Yogyakarta dan dilakukan sesuai dengan prosedur/metode uji yang digunakan oleh BBTKLPP. Hasil tak beraturan ditunjukkan kedua filter untuk parameter kekeruhan dan kesadahan dimana terjadi peningkatan kekeruhan dan kesadahan pada air hasil filtrasi, sehingga dapat disimpulkan bahwa teknologi ini bukan teknologi yang tepat untuk mengurangi kekeruhan dan kesadahan. Terjadi peningkatan kandungan Total Coliform dan E.coli pada air hasil filtrasi untuk filter komposisi kasongan. Hasil berbeda ditunjukkan filter dengan campuran serbuk kayu serta pelapisan perak nitrat dimana dari lima kali pengambilan sampel, filter mampu menurunkan kandungan Total Coliform dan E.coli pada air hasil filtrasi dengan rata-rata 77,9% dan 96,15%.

Abstract
This research is motivated by concerns about the low achievement of students spiritual competencies, even in Islamic schools. One of the reasons is the limited availability of teaching materials that can help teachers to associate science subject towards Islamic values. Even though, teaching materials are an important part to determine the success of the learning process. In Islamic schools, teachers are required to internalize Islamic values into the subject, including in chemistry. Unfortunately, not all teachers understand the process of internalization in any chemical material taught. One of them is the buffer solution material. The aim of this research is to examine the process of internalization of Islam into buffer solutions teaching materials. The analytical method in this paper is based on scientific integration between general science and religious science (non-dichotomic). Internalization of Islam in buffer solution teaching materials conducted by including the verses of Quran and hadith that are related and strengthening the material in the form of case studies of the phenomenon of buffer solutions in everyday life and doing exercise. Based on the research, teachers and students gave a positive response to the procurement of teaching materials which internalized in Islamic values.

Abstract
Variations of volume transport in the Halmahera Sea are strongly influenced by the El Nino Southern Oscillation (ENSO). Based on the ENSO Index at Nino 3.4, in 2011 La Nina event took place with a strength of -1.4, while in 2015 El Nino occurred with a strength of +2.6. This paper discusses the variation of transport volume caused by the ENSO phenomenon based on the results of the Regional Ocean Model System (ROMS). On the Halmahera Sea at a latitude of 0.3(^circ)S with a width of 67 km and a depth of up to 300 m, net volume transport always moves southward. The largest volume transport in La Nina 2011 occurred in September-October, which was -8.9 Sv. Meanwhile, in El Nino 2015 the largest volume transport occurred in July-August, which was equal to -4.9 Sv. The cross correlation coefficient between volume transport and SOI in 2011 and 2015 respectively was r = 0.55 and r = 0.61, where these results indicate a strong relationship.

Abstract
The purpose of this research was to obtain an overview of the impact of teacher certification on improving the quality of learning. This study used a qualitative descriptive method with the research instrument used was a questionnaire and interview. The respondents in this study were 50 certified elementary school teachers in northern Bandung and central Bandung. The results of the study showed that teacher certification has not had a significant effect on improving the quality of learning, this can be seen from: a lack of teacher understanding of learning models; teachers lack mastery in thematic learning material; communication between teachers and parents is still not good, and; coordination between teachers and schools to get support for facilities is still not good. Therefore it is necessary to improve the quality of teacher competencies such as pedagogic competence, professional competence, competence, social competence and personality competence.

Abstract
The hydrokinetic turbine is one of the renewable energy without generating emission impacted on environmental. In this work, the numerical simulation is used to investigate the influence of discretization along the blade surface towards the amount of the torque coefficient and power coefficient. This work will be done on Savonius hydrokinetic turbine numerically by using the Myring formula for n equal with 1 having the performance better than the conventional blade. This work will compare the performance among the blade discretization. Firstly, the numerical will be done the validation with experimental results at TSR of 0.8 and velocity of fluid kept constant at 0.22 m/s. Problem-solving uses Unsteady RANS with moving mesh for the rotating body. The turbulence model uses the Realizable k-epsilon (RKE) enhanced wall treatment with the discretization varied 800 and 1600. The layer number is 20 layers by varying the first layer on the blade surface of 1 and 1.2. This work focuses to obtain the torque coefficient and power coefficient. The results indicate that the increase of discretization on the surface of the blade has improved the accuracy results of the turbine performance.

Abstract
Bamboo fibers have advantages of renewable, biodegradable, abundant availability, and cheap which could be a potential substitute of synthetic materials. Tensile strength of this bamboo is important requirements in various structural application. In this research, fiber fabrication process optimization of 3 types of local bamboo namely Gombong (Gigantochloa pseudoarundinacea), Haur Hejo (Bambusa tuldoides), and Tali (Gigantochloa apus) was investigated. These fibers were processed by varying the NaOH concentrations, immersion times, and immersion temperatures. The process parameters and its level variations of bamboo fiber fabrication were optimized using Taguchi method. Then the contribution of each process parameter was observed using the analysis of variance (ANOVA). From Taguchi method, the optimal parameter for highest tensile strength was obtained from Tali bamboo, indicated by 4% NaOH, 2 hours immersion time, and 60oC immersion temperature. From ANOVA, the contributions for each parameter are 70 % for bamboo type, 7 % for NaOH concentration, 4 % for immersion time, and 17 % for immersion temperature with error contribution of 2%. FTIR analysis was carried in order to observe chemical bonding in bamboos which were indicated Tali bamboo has larger lignin levels decreasing than Haur Hejo and Gombong.

Abstract
The prevalence of breast cancer remind high. Women are suggested to conduct a Self Breast Examination (BSE) to identify abnormal lumps in the breast. However, research around exposure to information about BSE is currently limited especially among school age. The objective of this study was identify the correlation between exposure to information about BSE and perceptions as well as behavior of early detection of breast cancer in female teenagers in Kertayasa Tourism Vocational School. This study was descriptive correlation study with cross-sectional approach. Respondents were 167 female students year 10 and 11. Data was collected using a self-developed questionnaire and analyzed using Spearman Rho. The majority of respondents (60.5%) were aged 16 years. Findings indicated that there was a significant relation between exposure to information and perception, rs= .334, n= 167, p<0.001 with high exposure score associated with high perception score. Similarly, there was also a significant relation between information exposure and behavior, rs= 0.504, n=167, p<0.001with high exposure score associated with high behavior score. Health practitioners are expected to increase the exposure to information to the teenagers through health education.

Abstract
Caregiver burden is a multi-dimensional stress consist of physical pressures, psychologist, emotional, social, and financial which related to activities in caring children with special needs. The aim of this study was to identify the burden of parents in caring for children with mental retardation in 2 special need schools in Badung Regency. This was a descriptive study with cross sectional approach. Respondents were 265 parents of students with special needs. Zarit Burden Interview (ZBI) was used for data collection, and analyzed using univariate analysis. Among 265 respondents, 51.7% respondents were female parents. Median age was 47 years old (ranged from 24 to 66 years old). The majority of parents (67.5%) had children with mild mental retardation. Univariate analyses indicated that 80% had a mild to moderate burden, 7.2% had moderate to severe burden, and only 0.4% had severe burden. Maanwhile, and 12.5% indicated no burden. Health practitioners are expected to provide education to the parents to reduce the dependency of children towards their parents and to improve the parents coping mechanism in caring for children with special needs.

Abstract
An earthquake was one of the natural disasters which caused a lot of damage and causalities. Children are vulnerable to disaster, therefore they need to be provided with knowledge about earthquakes since elementary school age. Providing health education with audiovisual is a way that can be done to increase knowledge about earthquakes, so the risk of increasing casualties can be reduced. This study aimed to determine the effect of health education using audiovisual on the knowledge of elementary school students about earthquakes. This research implemented pre-experimental design with one group pre-test and post-test. Respondents were 57 student grade five and six in a Public Elementary School 3 Abuan. Data were collected using a self-developed knowledge questionnaire and was analyzed with Wilcoxon Sign Rank Test. The majority of respondents were female (52.6%), with age ranged from 10-12 years. Wilcoxon sign rank test revealed a statistically increase in knowledge after receiving education. Z value =-6.697, p<0.001, r =0.63, median score increased from pre-program (Md= 11) to post -program (Md= 14).There is the effect of providing health education using audiovisual on the knowledge of elementary school students about disaster preparedness.
