Abstract

Di Indonesia, produksi, impor, dan distribusi pangan harus mematuhi standar ketat yang mencakup kriteria keamanan, kualitas, dan gizi pangan. Peraturan ini mencakup penetapan ambang batas maksimum pencemaran logam berat., perusahaan makanan besar biasanya menggunakan sistem pendeteksian logam yang baik. Sebaliknya, industri makanan skala kecil dan menengah cenderung menghindari penggunaan sistem deteksi logam canggih karena biayanya yang besar. Tujuan penelitian ini agar terciptanya alat deteksi logam pada makanan yang dapat deterapkan oleh industri menengah kebawah. Pada alat ini menggunaan metode sistem koil seimbang. Bukaan tempat produk bergerak dikelilingi oleh tiga kumparan. Pada inti deteksi terdapat kumparan pemancar yang memancarkan sinyal yang menghasilkan medan elektromagnetik,.sehingga koil antar sisi penerima dapat menerima sinyal elektromagnetik yang dapat berubah ketika adanya gangguan logam yang melewatiya,  gangguan tersebut dapat diketahui dengan megukur tegangan keluaran pada pemerima sehingga metode ini cocok untuk peterapkan pada deteksi logam makanan. Logam yang sangat kecil merupakan tantangan bagi sensor untuk dibuat dengan sensitifitas yang sangat tinggi , sehingga keberadaan logam didalam makanan dapat dideteksi dengan baik. Berdasarkan hasil dari pengujian alat ini logam berjenis besi (Fe), Alumunium (Al), Timbal (Pb), dan Stainless (Ss) dengan ukuran masing-masing 0,1 gr, 0,2 gr, 0,3 gr, 0,4 gr, dan 0,5 gr dapat dideteksi dengan pembacaan beda  tegangan pada millvolt. Sistem komunikasi antara sistem pedeteksi dan penyortir bekerja sangat baik sesuai dengan cara kerja alat.

Abstract

Introduction. Providing school library services to increase students' interest in reading is still an important study for school libraries. Increasing reading interest in the SMAN 4 Tangerang Selatan Library is carried out by providing collaborative services to improve scientific communication. This research needs to be carried out so that the services provided by the library can accommodate all students in reading interest services and become basic research for school libraries in the South Tangerang area.Methodology. This study uses a quantitative approach, with a correlation coefficient test to answer the hypothesis. The population is 346 students, so a sample of 186 respondents is obtained using a simple random sampling technique. Questionnaires were distributed to 186 students with Likert scale scores with four alternative answers and documentation studies to complete data collection.Results and Discussion. This study found a relationship between library services and students' reading interest, as evidenced by the contribution of 24.6% between library services and students' reading interest. In comparison, the remaining 75.4% was explained by other variables not examined. The tendency of library services to increase reading interest is still in the moderate category.Conclusion. This study describes the school's efforts to increase student's interest in reading with the strength of the services provided by the library. Reading skills need to be trained so that the more the library can provide the facilities needed for reading, the more trained students will be.

Abstract

The revolution on social media has attracted users to video sharing sites like YouTube. This site is the most popular social media site where people see, share and interact by commenting on videos. There are various types of videos shared by users such as songs, movie trailers, news, entertainment etc. Some time ago the most trending video was a video about World War III (WWIII / WW3). Analyzing comments from videos about WW3 gives viewers opinions about WW3. Study the sentiments expressed in this commentary whether WW3 gets positive or negative feedback. The machine learning algorithm, Naive Bayes, is used in comments to find out its sentiments. The test results of 1500 data produced 30.3% positive sentiment and 60.6% negative sentiment, with an accuracy of 78.17%.
