The results of collecting data is to analyze of stock price reaction. It shows that there is no stock price reaction before and after the announcement of the Working cabinet. Because of abnormal return only occurs on H-7 (0.024) and H+8 (0.018), while others do not. The researches used a writting test.

Abstract

Dinamika persaingan bisnis khususnya di dunia kesehatan mendorong pengusaha untuk menemukan strategi pemasaran produk obat yang efektif. Permasalahan penjualan produk obat pada Apotek Juang Jaya yang sering terjadi adalah penumpukan obat yang kurang diminati sehingga  menjadikan obat menjadi kadaluarsa. Penerapan sistem rekomendasi dapat meningkatkan penjualan obat yang diminati dan mengurangi kerugian dari produk yang kurang diminati,  dengan cara   mengolah data transaksi dan memberikan rekomenadasi obat yang memiliki keterhubungan. Algoritma Apriori atau sering disebut analisis asosiasi adalah salah satu teknik data mining untuk menemukan aturan asosiasi antara suatu kombinasi item dalam data transaksi penjualan. Aturan asosiasi ini bertujuan untuk mendapatkan kombinasi antar item dan pola pembelian konsumen. Parameter aturan asosiasi yang digunakan adalah nilai support, nilai confidence, dan pengujian menggunakan nilai lift untuk mengetahui aturan asosiasi valid atau tidak. Dalam perhitungan menggunakan algoritma Apriori, nilai support yang digunakan adalah 20%, dan nilai confidence yang digunakan adalah  60%. Hasil perhitungan pengolahan data pada Apotek Juang menggunakan algoritma Apriori mendapatkan aturan asosiasi sebanyak 7 rule, dimana hasil penghitungan korelasi positif tertinggi adalah membeli Pimtrakol, maka membeli Bodrexin Flu dengan   nilai support 22,58%, nilai confidence 77,78% dan nilai pengujian lift adalah 1,85 yang berarti aturan asosiasi valid.

Abstract

The need for renewable energy is urgently needed at this time to replace fossil energy as a source of electricity generation. The use of environmentally friendly renewable energy continues to be developed in order to deal with the energy crisis and create a healthy environment. The purpose of writing this final project is to analyze the electrical power resulting from the conversion of cow dung in a biogas power plant, so as to produce the efficiency value of biogas as a power plant. In this final project, electric power is generated from biogas and LPG gas which are converted using a generator set, after which the comparative values of biogas and LPG gas are obtained. The location of this research was conducted at a cattle farm in Girinata Village, Dukuntang District, Cirebon Regency. Calculations are made using varying loads, LPG gas fuel produces electricity that is quite stable compared to biogas which is still unstable. The stability of the electric power is generated due to the presence of high and stable fuel pressure, the more stable the pressure, the stable the generated electric power.

Abstract

Abstrak Penelitian ini bertujuan untuk mendapatkan data yang tepat, benar, valid serta dapat dipercaya dan diandalkan tentang Pengaruh Lingkungan Sekolah Ramah Anak Terhadap Kedisiplinan Siswa DI SMAN 107 Jakarta Timur. Seberapa besar pengaruh diantara keduanya terbilang cukup atau sedang serta faktor-faktor yang mempengaruhi. Penelitian ini menggunakan metode “deskriptif analitik korealsional” adapun objek penelitian adalah siswa kelas X IPA 1, X IPA 2 dan X IPS 2, X IPS 3 SMAN 107 Jakarta Timur, yang berjumlah 590 siswa. teknik pengumpulan data menggunakan angket dan tes sebanyak 118 responden. Dilengkapi juga teknik obeservasi, dan wawancara. Sedangkan dalam menganalisis data menggunakan Product Moment dari Karl Pearson. Hasil penelitian yaitu jika dilihat dari segi uji koefisien product moment menghasilkan rxy atau ro sebesar 0,511 hal ini menunjukkan bahwa ro lebih besar dari pada rt pada taraf signifikan 5% = 0,174 dan lebih kecil dari pada rt pada taraf signifikan 1% = 0,228. Membandingkan besarnya “rxy” dengan “rt” seperti yang diketahui rxy yang peneliti peroleh adalah 0,511 sedangkan rt masing-masing 0,174 dan 0,228. Dengan demikian ternyata bahwa rxy ≥ rt pada taraf signifikan 5% dan rxy ≤ rt pada taraf signifikan 1%. Dalam hal ini berarti terdapat Pengaruh Lingkungan Sekolah Ramah Anak Terhadap Kedisiplinan Siswa pengaruhnya cukup. Korelasi tersebut adalah kedisiplinan sangat diperlukan dalam Lingkungan Sekolah Ramah Anak . Kata Kunci : Lingkungan Sekolah Ramah Anak, Kedisiplinan Siswa This study aims to obtain precise, correct, valid and reliable and reliable data about the Influence of a Child-Friendly School Environment on Student Discipline at SMAN 107 East Jakarta. How much influence between the two is sufficient or moderate and the factors that influence it. This study used the "descriptive analytic koreanal" method while the objects of research were students of class X IPA 1, X IPA 2 and X IPS 2, X IPS 3 at SMAN 107 East Jakarta, totaling 590 students. data collection techniques using questionnaires and tests of 118 respondents. Also equipped with observation techniques, and interviews. Meanwhile, in analyzing the data using Product Moment from Karl Pearson. The results of the study are that when viewed in terms of the product moment coefficient test it produces rxy or ro of 0.511. This shows that ro is greater than rt at a significant level of 5% = 0.174 and smaller than rt at a significant level of 1% = 0.228. Comparing the magnitude of "rxy" with "rt", as is known, the rxy that the researchers obtained was 0.511 while the rt was 0.174 and 0.228, respectively. Thus it turns out that rxy ≥ rt at a significant level of 5% and rxy ≤ rt at a significant level of 1%. In this case, it means that there is an Influence of the Child-Friendly School Environment on Student Discipline, the effect is sufficient. This correlation is that discipline is very much needed in a Child Friendly School Environment. Keywords: Child Friendly School Environment, Student Discipline
