Classification is one of the most widely used techniques in machine learning. Text classification is the process of classifying data according to pre-determined groups or classes. Where in most cases, text classification uses labeled training data to obtain the rules used to classify test data into predefined groups. In this study, it is proposed to use CountVectorizer for Indonesian text classification which will be compared with TF-IDF Term Weighting and its three feature levels, namely Character Level, Word Level and N-gram Level as feature extraction which is implemented together with Naive Bayes classification and the BPPPTIndToEngCorpusHalfM dataset. To compare the classification performance, this study uses 10-Fold Cross Validation and Split Data using a ratio of 90:10, while to evaluate the accuracy of the authors using the F1-Score and AUC with the hope that this study will get good accuracy results so that it can be used as a reference to be developed using another method. The F1-Score accuracy obtained in this study was 0.93 and the AUC score was 0.95.

Diabetes melitus menjadi masalah kesehatan di dunia karena terjadi peningkatan setiap tahun. Oleh karena itu dibutuhkan obat atau agensi terapi yang efektif dan murah untuk menanggulangi diabetes melitus. Ekstrak kulit terong Belanda mempunyai kandungan antosianin dan betakaroten yang memiliki kemampuan menurunkan kadar gula darah, sehingga dapat dijadikan sebagai obat tradisional yang efektif dan murah. Tujuan penelitian ini adalah untuk menganalisis pengaruh pemberian ekstrak kulit terong Belanda terhadap penurunan kadar gula darah tikus wistar jantan yang diinduksi aloksan. Metode penelitian ini menggunakan rancangan penelitian pre and post test randomized controlled group design. Penelitian ini menggunakan tikus wistar jantan sebanyak 25 ekor  yang dibagi menjadi 5 kelompok perlakuan yaitu perlakuan dengan aquadest (kontrol negatif), ekstrak kulit terong Belanda (Solanum betaceum) dosis 0,25 ; 0,75 ; 1,25 g/kg BB dan metformin sebagai obat diabetes dengan dosis 18 mg/tikus (kontrol positif). Semua kelompok diinduksi aloksan sampai dengan kadar gula darahnya mencapai ≥ 200 mg/dL lalu diukur kadar gula darah sebagai data pre test. Perlakuan diberikan selama 14 hari dan pada hari ke – 14 diukur kadar gula darah sebagai post test. Ekstrak kulit terong Belanda dosis 0,25; 0,75 dan 1,25 g/kg BB mampu menurunkan kadar gula darah secara signifikan selama 14 hari akan tetapi belum ada dosis yang memiliki efektifitas yang sebanding dengan metformin dalam penurunan kadar gula darah apabila diberikan selama 14 hari.Kata kunci: Ekstrak kulit terong Belanda, diabetes, tikus, aloksanABSTRACT Diabetes melitus is a health problem in the world because the sufferers increase from year to year. So that it is needed an effective and economical drug or therapeutic agency to cope with the disease. Tamarillo peel extract contains anthocyanin and beta-carotene which are capable to reducing blood sugar levels, so that it can be used as an effective and economical traditional medicine. The aim of the study was to analyze the effect of the administration of Tamarillo peel extract on decreasing blood sugar levels in male wistar rats induced by alloxan. The research method used a pre and post test randomized controlled group design. This study used 25 male wistar rats divided into 5 treatment groups namely aquadest treatment (negative control), metformin as a diabetes drug with a dose of 18 mg / rat (positive control), and Tamarillo skin extract (Solanum betaceum) dose 0, 25; 0.75; 1.25 g / kg BB. All treatment groups were induced by alloxan until their blood glucose levels reached ≥ 200 mg / dL then measured blood sugar levels as the pre test data. The treatment was given for 14 days and on the 14th day blood sugar levels were measured as a post test. Tamarillo peel extract dose of 0.25; 0.75 and 1.25 g / kg BB can significantly reduce blood glucose levels for 14 days but there is no dose that has an effectiveness comparable to metformin in reducing blood glucose levels if given for 14 days.Keywords: Tamarillo peel extract, diabetes, rats, alloxan

Yoghurt merupakan salah satu produk fermentasi yang menggunakan susu sebagai bahan dasar. Penelitian ini menggunakan bahan dasar susu nabati yang berasal dari kacang gude ekstrak umbi bit sebagai bahan tambahan. Tujuan penelitian ini adalah untuk menentukan rasio kacang gude kering dan ekstrak umbi bit yang tepat untuk menghasilkan yoghurt kacang gude yang mempunyai aktivitas antioksidan tinggi dan untuk menentukan tingkat penerimaan konsumen terhadap yoghurt kacang gude dengan penambahan ekstrak umbi bit. Rancangan percobaan yang digunakan yaitu Rancangan Acak Lengkap (RAL) dengan faktor pertama yaitu kacang gude kering sebesar 20%, 30%, 40% dan faktor kedua yaitu ekstrak umbi bit 5%, 10%, 15%. Analisis kimia yaitu analisis aktivitas antioksidan, gula total, protein, total asam, dan lemak. Analisis organoleptik yaitu warna, kekentalan, rasa asam, flavor kacang gude dan kesukaan keseluruhan. Hasil penelitian menunjukkan bahwa perlakuan 20% kacang gude kering dan ekstrak umbi bit 15% adalah perlakuan terbaik yang didasarkan pada kesukaan keseluruhan yang terdapat pada yoghurt. Dari komposisi tersebut terdapat aktivitas antioksidan DPPH 58,35%, kadar gula 2,77%, kadar protein 39,90%, total asam 1,17%, dan kadar lemak 0,19%. Sedangkan yoghurt yang memiliki aktivitas antioksidan tertinggi didapatkan pada komposisi 30% kacang gude dan ekstrak umbi bit 15% dengan nilai aktivitas antioksidan sebesar 65,23%. Pada perlakuan ini mengasilkan kadar gula 2,80%, kadar protein 46,96%, total asam 1,26%, dan kadar lemak 0,11%. Kata kunci: Kacang gude, ekstrak umbi bit, yoghurt, aktivitas antioksidan ABSTRACT Yogurt is one of the fermented products that used milk as a basic ingredient. This research used basic ingredients of vegetable milk derived from pigeon peas and used beet root extract as an additional material. The purpose of this study was to determine the ratio of dried pigeon peas to water and beet root extract that are appropriate for producing pigeon peas yogurt that had high antioxidant activity and to determine the level of consumer acceptance of pigeon peas yogurt with the addition of beet root extract. The experimental design used the Completely Randomized Design (CRD) with the first factor was dried pigeon peas of 20%, 30%, 40% and the second factor were beet root extract 5%, 10%, 15%. The chemical analysis was antioxidant activity, total sugar, protein, total acid, and total fat. Organoleptic analysis of color, viscosity, sour taste, flavor of pigeon peas and overall preference. The results showed that the combination treatment of 20% dried pigeon peas and 15% beet root extract was the best treatment. From the composition there is DPPH antioxidant activity 58,35%, 2,77% sugar content, 39,90% protein content, 1,17% total acid, and 0,19% fat content. Whereas yogurt with the highest antioxidant activity was found in the composition of 30% pigeon peas and 15% beetroot extract with antioxidant activity values of 65,23%. In this treatment yielded 2,80% sugar content, 46,96% protein content, 1,26% total acid, and 0,11% fat content. Keywords: Pigeon pea, beet root extract, yoghurt, antioxidant activity

Clove plant (Syzygium aromaticum. L) Is one of the plants known by the people in Bula village as a traditional medicine the leaves of cloves (Syzygium aromaticum folium) are often used as an alternative to cure stiff and rheumatic diseases such as causing pain due to excessive activity, so that it can be used as an active ingredient in making ointments The purpose of this study was to identify the chemical content of clove leaves (Syzygium aromaticum folium) from Bula village and to formulate a good and stable clove leaf ethanol extract ointment (Syzygium aromaticum folium) using a ratio of variations in the concentration of the Hydrocarbon Base. This research method is experimental which was carried out using a combination base of vaseline album: cera alba from three different formulations with a concentration ratio of F1 (76%: 10 %), F2 (71%: 15%), F3 (66%: 20%), each formulation contains 10% ethanol extract of clove leaf (Syzygium aromaticum folium). Evaluation of ointment preparations was carried out after 1 week of storage; evaluation tests included organoleptic tests, homogeneity tests and pH tests. The results showed that the ointment preparations F1 (76%: 10%) met the requirements for a good and stable ointment, while F2 (71%: 15%), and F3 (66%: 20%) did not meet the requirements for a good and stable ointment.
