This paper presents The research on e-modules is based on problem solving for science process skills. E-modules are made with the stages of development, implementation, and evaluation adopted from the Branch. The purpose to see the science process skills and physical education students' perceptions of Edinburgh University after using e-module basic physics lab-based science process skills using the model of problem solving using kvisoft application.

AbstrakSumber air tanah yang banyak dimanfaatkan warga adalah air sumur gali. Air sumur gali bila kondisinya tercemar baik oleh limbah domestik maupun limbah industri menyebabkan dampak terhadap kesehatan manusia. Penelitian ini bertujuan untuk mengetahui tingkat polusi dan faktor-faktor yang menyebabkan polusi air tanah akibat limbah domestik dan limbah industri di Kelurahan Kalikabong Kabupaten Purbalingga. Penelitian kuantitatif ini dilakukan pada tahun 2012. Keseluruhan data di uji statistik deng an Fisher's Exact Test. Hasil analisis bivariat menunjukkan tidak ada hubungan antara kekeruhan (p value 1,000), bau (nilai p value 0,183), warna (p value 1,000), dan rasa (p value 0,346) dengan polusi air tanah.Hasil analisis univariat menunjukkan terdapat 100% air sumur warga tidak memenuhi syarat secara mikrobiologi. Air sumur warga yang bau 47,63%, berasa 38,09%, berwarna 33,33%, keruh 28,57%. Faktor-faktor yang menyebabkan timbulnya polusi air sebesar 33,33% berasal dari limbah industri, 47,62% limbah rumah tangga, dan 19,04% berasal dari limbah perkotaan. Untuk mengurangi pencemaran air sumur gali disarankan bagi penduduk setempat untuk pembuatan tangki septik secara komunal. LAND WATER POLLUTION FROM INDUSTRIAL WASTE AND DOMESTIC WASTE Abstract Many people use ground water from their wells. However, it will cause health problems if the water is contaminated by either domestic or industrial waste. This research is aimed at finding the level of pollution and the factors causing the ground water pollution by industrial and domestic waste in

The study used mixed-method design. Sample size of this study was 689 students employed total sampling technique. This study revealed that science process skill of students in learning science whether urban and rural areas are good. The independent sample t-test showed that there was a significance difference in students' science process skill in urban school (M = 3.175, SD = 0.178) and in rural schools (M = 2.482, SD = 0.182); (t (687) = 18.224, p<0.01. The independent sample t-test showed that there was a significance difference in students' critical thinking in urban school (M = 5.058, SD = 0.163) and in rural schools (M = 3.436, SD = 0.152); t (687) = 17.224, p<0.001. Lastly, the regression shows the level of contribution students’ science process skill influence as much as 51.5% for critical thinking. This study was found that student science process skill affects critical thinking in learning science. Moreover, students' science process skill and critical thinking in urban better than rural.

Abstract. Yulianah I, Waluyo B, Ashari S, Kuswanto. 2020. Variation in morphological traits of a selection of Indonesian winged bean accessions (Psophocarpus tetragonolobus) and its analysis to assess genetic diversity among accessions. Biodiversitas 21: 2991-3000. In Indonesia, winged bean (Psophocarpus tetragonolobus (L.) DC.) is a traditional vegetable crop grown mainly for its edible green pods. Plant breeding programs aim to produce cultivars with high production and good nutritional qualities. The objective of this present study was to assess genetic diversity among 21 selected Indonesian winged bean lines based on observation of morphological characters. This was the first step in determining an appropriate breeding program for the development of improved vegetable cultivars. Twelve qualitative characters and eight quantitative variables were assessed for each of the 21 lines. Categorical differences among lines were observed in characters such as leaflet, pod and seed shape, pod surface texture, anthocyanin pigmentation of stem, flowers and pods. Several of these characters are useful as genetic markers, and cluster analysis of the 21 lines on the basis of qualitative characters enabled two distinct groupings to be identified. Quantitative variation across line means was also high for several of the quantitative variables (a coefficient of variation > 25% for pod length, number of pods per plant, and total pod weight per plant). Principal component analysis applied to the eight variables accounted for 86% of the total variation in just three components with eigenvalues > 1. On Component 1, the characters number of days to first open flower, pod length and pod weight were closely aligned with total weight of pods per plant. Number of pods per plant was not closely aligned with weight of pods per plant. This study has enabled broad differences between groups of lines to be categorized and has identified particular lines with characteristics that recommend them for inclusion as parents in inheritance studies designed to elucidate the contribution that individual characters make to overall productivity, attractiveness, and nutrition of this useful, high protein, vegetable species.
