Tujuan penelitian ini untuk melakukan evaluasi terhadap kualitas delapan mata air berdasarkan sifat fisik dan kimia air. Penelitian dilakukan di mata air Ngenep, PraNyolo, Umbulan, Langgar, Balittas, Lowoksari, Leses dan Soko yang terletak di Kecamatan Karangploso Kabupaten Malang. Pada Â masingâmasing Â mata air Â tersebut Â dilakukan Â pengambilan sampel air Â pada dua titik sebagai ulangan. Parameter Â yang diukur meliputi suhu, pH, DO, konduktivitas, turbiditas, BOD, nitrat, ortofosfat, alkalinitas, TDS, TSS, TOM dan debit. Perbedaan kualitas fisikokimia air antar mata air ditentukan dengan uji Anova yang dilanjutkan dengan Duncan Multiple Range test, analisis cluster dan PCA. Hasil penelitian menunjukkan bahwa delapan mata air yang dipantau sudah tidak layak digunakan sebagai bahan baku air minum. Parameter yang sudah tidak memenuhi Â baku mutu Â berdasarkan Â PP No 82 tahun 2001 tentangÂ Pengelolaan Â Kualitas Â Air dan Â Pengendalian Pencemaran Air adalah nilai DO (semua mata air), BOD (mata air Â PraNyolo), Nitrat (mata air Â Langgar, Balittas, Lowoksari, Leses, Soko).

21st century learning demands the integration of Information and CommunicationTechnology (ICT) in teaching and learning process. Regarding this issue, this research isaimed at investigating English as a foreign language (EFL) teacherâs belief and practices onthe integration of ICT in English language teaching. To reach the objective, a case study onan individual teacher was used in this research. The participant was purposively andtheoretically selected because she was considered as the informant who could givesufficient information to answer the research questions. Teacherâs interview and classroomobservation were used as the data collecting techniques. Iterative data collection andanalysis were conducted continuously till theoretical pattern of concepts and categorieswere achieved. The Substitution Augmentation Modification Redefinition (SAMR) modelwas used as the data analysis tool resulted from the classroom observation to reveal to whatextent the teacher implements ICT integration. The results of this research indicate that theteacher believes that integrating ICT is very important as ICT has ability to maketransformation of all educational aspects by making use of it to reachinstructional objectives then the quality of teaching and learning will improve. Theresults also indicate that there is no discrepancy between belief and practice as the teacherhas been integrating ICT in the classroom. However, the teacher is still on the substitutionand augmentation stages in integrating ICT and hardly achieves modification and redefinitionstages. These results suggest that teachers be prepared for ICT integration to create moremeaningful learning in the classroom.

The aim of this paper was to investigate the influences of informal digital learning of English (IDLE) speaking practices which emerge the boundaries between countries. The researcher used questionnaire, interview, document analysis, and observation as data collection. For analyzing qualitative data, the researcher used narrative inquiry model including data collection, data transcription and reporting the narrative study. The participant were two female undergraduate students of English department in Indonesia. The result explained that IDLE speaking practices influence their self-confidence, motivation, and communication competence. This research also reveald that their language learning strategy through IDLE speaking practice widen their social and culture understanding. This new language learning strategy in informal context helps digital natives in this era to enjoy their learning.

Penguasaan siswa terhadap materi bangun ruang sisi datar masih mengalami kesulitan dan hambatan dalam memahami konsep dan prinsip karena cenderung pada menghafal tanpa membangun. Penelitian ini bertujuan untuk menganalisis desain pembelajaran bangun ruang sisi datar dengan pendekatan konstruktivisme dan model discovery learning berdasarkan perspektif teori situasi didaktis. Penelitian ini termasuk pada model Didactical Design Research (DDR) dengan hanya menggunakan tahapan pertama yaitu Prospective Analysis atau Pra observasi Pembelajaran. Guru model yang merancang desain pembelajaran ini dijadikan sebagai partisipan atau subjek penelitian, informan dan instrumennya. Teknik pengumpulan data berupa wawancara pada guru model serta menganalisis desain pembelajarannya. Analisis data yang dilakukan yaitu Prospective Analysis dengan langkah meliputi: 1) menentukan konsep kajian dan pendekatannya, 2) melakukan kajian literature, 3) melakukan wawancara, 4) menganalisis desain pembelajaran, 5) memprediksi dugaan hambatan belajar, 6) menarik kesimpulan. Berdasarkan analisis perangkat berupa RPP dan LKS, RPP secara keseluruhan telah mencakup seluruh komponen, namun terdapat beberapa komponen yang belum lengkap atau masih memiliki kekurangan seperti pada komponen KI, KD dan IPK, materi, media, sumber belajar, dan langkah-langkah pembelajaran. Sedangkan LKS yang dirancang telah sesuai dan memenuhi setiap sintaks model discovery learning serta pendekatan konstruktivisme meskipun terdapat beberapa learning obstacle dalam penyajiannya maupun pada soal non rutin.

Linear programming is a mathematical method used to solve problems related to linear optimization (maximum value and minimum value). Quoted from Mathematics 3 competency by Johanes, linear programming is a part of mathematics in the form of models, which consist of linear inequalities as a method for solving various problems in everyday life. This linear program can help solve problems ranging from basic to complex. This article aims to apply the use of linear programming in determining the maximum profit that can be obtained for managers of healthy wedang products. In this case, traders of ginger wedang products can use linear programming using the simplex method to find maximum profits manually and analyze using POM-QM for Windows software. The results of the analysis using the linear program of the simplex method with calculations on POM-QM have the same results, namely the maximum profit of MSME houses wedang sehat buk Sumiati in one day reaches Rp. 180,000 by producing healthy wedang ginger powder (X1) as much as 1 piece and wedang sehat suetajarah (X2) as much as 1 piece.
