Kualitas suatu batubara dapat ditentukan dengan cara analisa secara fisik maupun kimia. Umumnya untuk menentukan kualitas batubara dilakukan analisa kimia pada batubara yang diantaranya berupa analisis proksimat dan analisis ultimat. Metode yang digunakan untuk menentukan total moisture yaitu dengan metode gravimetri dan penentuan nilai kalori dengan menggunakan alat bomb calorimeter dengan prinsip kerja asaz black. Hasil nilai total moisture yang didapat 17,53%, 20,79%, 17,92%, 21,07%, 10,73%, 19,43%, 20,07%, 21,76%, 22,79%, 32,12%. Dan nilai gross calorivic value basis adb yaitu 6836 cal/g, 6511 cal/g, 6738 cal/g, 6456 cal/g, 7075 cal/g, 6706 cal/g, 6685 cal/g, 6688 cal/g, 6535 cal/g, 6484 cal/g. Hasil total moisture yang diuji didapatkan berada pada rentang 10.43% - 32.12%, dengan rata - rata 20.42%. Nilai gross calorific value (GCV) didapatkan berada pada rentang 6456 – 7075 kal/g yang di mana kalori pada rentang tersebut masuk ke dalam klasifikasi bituminous. Hasil total moisture tersebut disimpulkan berada di atas standar yang diterapkan perusahaan yaitu sebesar 11%. Hubungan antara Total Moisture dan Gross Calorivic Value berbanding terbalik. Karena semakin tinggi Moisture pada suatu batubara maka nilai kalori yang dihasilkan akan rendah.","PeriodicalId":405856,"journal":{"name":"Journal of Innovation Research and Knowledge","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128009258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ACL is easily at risk for injury, such as a rupture or tear. ACL occurs by contact or non-contact at the knee. Most injuries occur due to no-contact conditions almost 75% of cases. Mr. I was 16 years old on 2011 the patient injured his left knee while playing basketball. After that, there was so much pain around his left knee that he was unable to walk on his own. On October 29 2021, the patient underwent ACL and meniscus post-restructive surgery at the RSPI. After surgery, 1 week later the patient underwent physiotherapy at the Esa Unggul Sport Clinic, Jakarta. Patients undergo therapy four times in two weeks with a physiotherapy program that includes TENS, Quadriceps Set, Hamstring and Gastroc Stretching, Mobilization Exercises on the legs, Core exercise, Balance (passing ball), Exercises using Ankle. Patients were evaluated using antropometri, spygmomanometer, and goniometer. after 4 treatments the patient experienced a decrease in left knee edema, increased muscle mass, and increased contraction.","PeriodicalId":405856,"journal":{"name":"Journal of Innovation Research and Knowledge","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125418878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Berdasarkan penelitian yang dilakukan penyebab penurunan produksi padi ini Luas Lahan (Ha), Jumlah Pupuk (ton) dan curah hujan (Mm). Berdasarkan hasil scatterplot yang dilakukan variabel prediktor yang mempengaruhi produksi padi, sebagian memiliki pola tertentu dan sebagian lagi tidak memiliki pola tertentu (acak), sehingga model regresi terbaik untuk dapat memodelkan produksi padi menggunakan model regresi semiparametrik menggunakan estimator spline truncated. Salah satu metode yang digunakan untuk memilih titik knot optimal adalah dengan menggunakan metode GCV (generalized Cross Validation). Berdasarkan analisis yang dilakukan diketahui bahwa nilai GCV minimum terdapat pada model spline truncated dengan kombinasi knot (2,3,1), Sehingga, dapat disimpulkan bahwa model regresi semiparametrik spline truncated yang paling baik adalah spline dengan kombinasi knot dengan jumlah parameter model sebanyak 12 sudah termasuk ????0 (konstanta). Selanjutnya hasil estimasi dan observasi produktivitas padi dapat dimodelkan dengan cukup baik menggunakan model regresi semiparametrik spline truncated, karena nilai hasil estimasi dan observasi cukup dekat satu dengan yang lain, artinya hasil estimasi hampir mendekati nilai observasi.","PeriodicalId":405856,"journal":{"name":"Journal of Innovation Research and Knowledge","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114423599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
