This study aims to determine the description of the application of fingerprint electronic attendance at the Center for Early Childhood Education and Community Education in South Sulawesi. This research is a quantitative descriptive. The study population was all employees, amounting to 136 people because of the large population, this study conducted 50 percent sampling so that the sample was 68 people. The techniques used in data collection are observation, questionnaires, interviews, and documentation. Data analysis is presented through a frequency table and processed through a score calculation technique. The data analysis technique in this study uses the percentage formula. The results of this study indicate that the effectiveness of the application of fingerprint electronic attendance at the Center for Early Childhood Education and Community Education in South Sulawesi has been implemented very well or very effectively. These results are seen from the aspect; target achievement, adaptability, job satisfaction, responsibility.

This research is conducted to obtain a description of students' difficulties in understanding and applying Pythagorean theorem based on the onto-semiotic approach. This research applies a qualitative approach with phenomenology interpretation design. Research data were collected using test and interview methods. The research result was deducted from students' answer sheets and interviews. Participants involved in this study were as many as 25 students of UPI Lab School Junior High School Bandung, who had learned Pythagorean theorem, 4 of which also participated in the interview. It showed that students found it complicated to comprehend definition, describe symbols or notations of mathematical objects, and interpret mathematical objects. Meanwhile, in solving problems related to the application of the Pythagorean theorem, students could describe procedure, algorithm, and technique in solving questions well.

Tujuan Penelitian ini adalah untuk mengetahui pengaruh dosis dan interval waktu pembarian pupuk organik daun gamal terhadap pertumbuhan dan hasil tanaman sawi (Brassica juncea L). Penelitian dilakukan pada Maret 2019 s/d Mei 2019 di Kebun Percobaan Agroteknologi STIPER Kutai Timur. Rancangan yang digunakan adalah Rancangan Acak Lengkap(RAL), dengan pola faktorial, dimana perlakuan  pemberian dosis pupuk organik daun gamal  terdiri atas 4 perlakuan yaitu : D0 = 0 ml L-1, D1 = 40 ml L-1, D2 = 80 ml L-1, D3 = 120 ml L-1, sedangkan perlakuan interval waktu pemberian terdiri atas 3 perlakuan yaitu I1 = 3 hari sekali, I2 = 5 hari sekali, I3 = 7 hari sekali. Seluruh perlakuan diulang sebanyak 3kali. Data dianalisis dengan analisis sidik ragam yangdilanjutkan dengan uji beda nyata terkecil pada tingkat signifikasi 5%. Variabel yang diamati meliputi tinggi tanaman sawi, jumlah daun tanaman sawi, berat segar per tanaman sawi.Tidak terjadi interaksi antara perlakuan dosis pupuk organik cair daungamal dan interval waktu pemberian terhadap seluruh variabel yang diukur.Hasil penelitian menunjukkan bahwa dosis pupuk organik cair daun gamal memberikan pengaruh yang nyata terhadap tinggi tanaman (8,332), jumlah daun (7,911) dan berat segar (7,027), sedangkan perlakuan interval waktu pemberian berpengaruh nyata hanya pada tinggi tanaman (8,076) dan jumlah daun (7,683).

Teachers' ability in overcoming to student errors is significantly affected by teachers' knowledge. Discussion and studies related to what knowledge teachers should possess have resulted in a theoretical framework. This article aims at describing teacher knowledge to responding student errors in Pythagorean Theorem proof using didactic mathematical knowledge approach. This research applies qualitative design. Five junior high school mathematics teachers in Indonesia participate in this study. Data were collected using written tests on teachers' competence and structured interview. Based on the analysis towards participants' responses, it can be concluded that teacher knowledge to overcome on student errors in Pythagoren Theorem proof is significantly affected by other knowledge components.

Perancangan Smart Parking bertujuan untuk merancang suatu alat mikrokontroler yaitu Smart Parking yang dapat menginformasikan dan mengarahkan pengendara mobil ke area parkir yang kosong. Lahan parkir yang dijadikan sebagai objek penelitian terdiri dari beberapa lokasi parkir dengan kapasitas beberapa kendaraan, namun penelitian ini hanya memilih bebarapa slot parkir sebagai sampel. Pada perancangan ini memiliki beberapa bagian umum yang digunakan, yaitu sensor ultrasonik HC-SR04, Arduino Mega, PC/laptop, LCD (Liquid Cristal Display) dan IOT (Internet Of Things) penelitian menunjukkan bahwa LCD akan menampilkan beberapa slot parkir yang sudah terisi dan beberapa lagi slot parkir yang kosong dan pemantauan melalui Smartphone dengan menggunakan aplikasi Blynk. Sedangkan untuk bagian palang pintu masuk area parkir menggunakan alat yaitu servo, dan Arduino UNO sebagai pengoperasian palang pintu parkir tersebut. Pada perancangan ini menghasilkan jarak pada sensor parkir di bawah 6 cm menandakan bahwa keadaan slot parkir terisi dan di atas 6 cm menandakan keadaan slot parkir tersedia pada LCD dan aplikasi Blynk tersebut. Sedangkan untuk servo palang masuk mendeteksi mobil pada jarak di bawah 5cm servo akan terbuka dengan delay 3 detik dan jika di atas 5 cm menandakan bahwa tidak ada mobil di depan palang sensor.
