Linear discriminant analysis is one of method frequently used and developed in the field of pattern recognition. This method tries to find the optimal subspace by maximizing the Fisher Criterion. Application of pattern recognition in highdimensional data and the less number of training samples cause singular within-class distribution matrix. In this paper, we developed Linear Discriminant Analysis method using Fukunaga Koontz Transformation approach to meet the needs of the nonsingular within-class distribution matrix. Based on Fukunaga Koontz Transformation, the entire space of data is decomposed into four subspaces with different discriminant ability (measured by the ratio of eigenvalue). Maximum Fisher Criterion can be identified by linking the ratio of eigenvalue and generalized eigenvalue. Next, this paper will introduce a new method called complex discriminant analysis by transforming the data into intraclass and extraclass then maximize their Bhattacharyya distance. This method is more efficient because it can work even though within-class distribution matrix is singular and between-class distribution matrix is zero.

Daging sapi sebagai sumber protein hewani, merupakan salah satu agent of development yang dapat menentukan daya saing sumber daya manusia suatu negara. Namun, konsumsi daging masyarakat Indonesia masih jauh lebih rendah jika dibandingkan dengan masyarakat dari negara-negara lain di ASEAN. Sementara itu, kesenjangan antara kebutuhan konsumsi dengan produksi daging sapi lokal terjadi tiap tahunnya, peternakan sapi potong nasional masih belum mampu memenuhi kebutuhan masyarakat akan daging yang terus meningkat, bahkan sapi lokal hanya dapat mensuplai kebutuhan daging nasional sebesar 49%. Program Swasembada Daging Sapi (PSDS) tahun 2014 yang dicanangkan Pemerintah pada tahun 2010 guna meningkatkan lonjakan populasi sapi dalam negeri pun menghadapi beberapa tantangan antara lain penyakit dan terbatasnya jumlah dokter hewan di daerah pedesaan. Sehubungan dengan permasalahan tersebut dan sejalan dengan visi serta salah satu sasaran dari Direktorat Kesehatan Hewan, maka diperlukan adanya sistem cerdas yang mampu mendeteksi penyakit sapi berdasarkan gejala-gejalanya yang bervariasi sehingga dapat dilakukan penanganan dini terhadap sapi tersebut yang dapat mencegah penyebaran penyakit. Pada penelitian sebelumnya [1], masih terdapat kelemahan pada input datanya karena hanya dapat memproses keseluruhan gejala penyakit dengan instance berupa “Ya” dan “Tidak”.

The study is conducted with the purpose of acquiring empirical evidence relatedto the influence of intellectual capital (IC) in calculation of value added(VAICTM) and also each components of IC, there are capital employed efficiencyValue Added of Capital Employed (VACA), Value Added Human Capital (VAHU)and Structural Capital Value Added (STVA) toward the financial performance(ROA) of Business Strategics there are Asset Utilization Efficiency (AUE) andPremium Price Capability (PPC) as an moderating variable.The data used in this study were obtained financial data from the financialstatements of each company and a sample. The method of analysis is fixed effectanalysis using multiple regression with SPSS version 23. The population used inthis study is a LQ45 company listed on the Indonesia Stock Exchange in 2011-2015, with a total sample of 18 companies.Based on this research, it was found that the variable Value Added of CapitalEmployed (VACA) and Value Added Human Capital (VAHU) have a significanteffect on Return on Asset (ROA), while Structural Capital Value Added (STVA)has no significant effect on Return on Asset (ROA). The relationship ofIntellectual capital (VAICTM) variable have a significant effet on the Return onAsset (ROA) through Asset Utilization Efficiency (AUE) and Premium PriceCapability (PPC) as an moderating variable.

World Health Organization (WHO) mengestimasikan prevalensi hipertensi secara global sebesar 22% dan kurang dari seperlima yang melakukan upaya pengendalian terhadap tekanan darah. Kepatuhan diet dan minum obat anti hipertensi, serta modifikasi lingkungan merupakan hal penting yang dapat mengontrol hipertensi. Pemberian edukasi dapat meningkatkan pemahaman dan kesadaran untuk mengikuti manajemen hipertensi yang disarankan. Penelitian ini bertujuan untuk menilai pengetahuan dan sikap responden setelah pemberian edukasi. Metode penelitian adalah Quasi Experimental denngan one group pretest-posttest design. Subyek penelitian adalah masyarakat di Rumkitban JS/08.00 Bintaro Jakarta Selatan dengan jumlah sampel 55 orang dari total populasi berjumlah 120 orang. Hasil penelitian didapatkan demografi responden dominan perempuan (69,1%), usia lansia (89,1%), memiliki pekerjaan (61,8%), penghasilan dominan di bawah UMR (60,0%), dengan tingkat pendidikan dominan (SMA 947,3%). Frekuensi pengetahuan menunjukkan terjadi peningkatan nilai rerata dari 61,63 menjadi 79,09, nilai rerata sikap responden dari 36,74 menjadi 41,57 dan persepsi responden tentang E-booklet hipertensi baik. Berdasarkan hasil tersebut dengan menggunakan uji Wilcoxon dapat disimpulkan terdapat hubungan antara E-Booklet dengan meningkatnya pengetahuan dan perubahan sikap.

The prevalence of anemia in pregnant women is 41.8 % . The causes of anemia in pregnancy include gravida, age, parity, education level, economic status and compliance with Fe tablet consumption, diet and physical activity. The purpose of this study was to determine the relationship between diet and physical activity with the incidence of anemia in pregnant women at Batunadua Health Center, Padangsidimpuan City in 2021 . The type of research is quantitative research with a cross sectional approach study . The population in this study were all pregnant women at Batunadua Health Center Padangsidimpuan City as many as 229 people. The sample in this study were 70 pregnant women at Batunadua Public Health Center, Padangsidimpuan City using random sampling method . The analysis used is Chi Square and Kolmogorov-Smirnov test . The results of this study indicate that there is a relationship between diet ( p=0.000) , and physical activity ( p=0.000) with the incidence of anemia in pregnant women. The conclusion is that diet and physical activity have a relationship with the incidence of anemia in pregnant women. Suggestions for pregnant women to increase antenatal care visits and find out about the incidence of anemia in pregnancy.
