"Saat ini teknologi 3D printing telah dikembangkan pada bidang farmasi khususnya teknologi produksi sediaan padat yang disebut tablet 3D printing. Hal ini dapat mendukung tujuan personalisasi sediaan farmasi khususnya terkait dosis obat. Salah satu metode yang dapat digunakan untuk personalisasi dosis obat untuk pasien yaitu tablet 3D printing. Penetapan dosis dibuat dengan merancang tablet 3D printing dengan volume tertentu menggunakan perangkat lunak untuk menyesuaikan dosis yang dibutuhkan. Penulisan ini bertujuan untuk mengkaji beberapa polimer yang dapat digunakan sebagai filamen dengan metode fused deposition modeling untuk pembuatan tablet 3D printing dan menganalisis profil pelepasan obat dari tablet 3D printing tersebut. Kajian ini berfokus untuk mempelajari karakteristik yang terdapat pada beberapa polimer yaitu poli asam laktat, polivinil alkohol, poli kaprolakton, polivinil pirolidon, poletilen oksida, etilen vinil asetat, etil selulosa, hidroksipropilmetil selulosa, dan hidroksipropil selulosa berupa sifat termoplastik, biodegradasi, dan sifat mekaniknya agar dapat diaplikasikan pada fused deposition modeling 3D printing. Selain itu, dipelajari pula pelepasan obat dari matriks tablet 3D printing. Hasil-hasil penelitian menunjukkan bahwa polimer yang dapat digunakan harus memiliki sifat termoplastik dan biodegradable. Polimer di atas dapat digunakan untuk membentuk filamen untuk pembuatan tablet 3D printing. Pilihan polimer yang digunakan berpengaruh pada profil pelepasan obat dari tablet 3D printing. Oleh karena itu, diajukan gagasan untuk membuat tablet dengan teknologi 3D printing dapat memfasilitasi modifikasi bentuk, ukuran, dosis dan profil pelepasan obat dari tablet. Tablet 3D printing dapat dikembangkan lebih lanjut menggunakan metode ini sehingga tujuan personalisasi obat dapat terwujud.

Currently 3D printing technology has been developed into the pharmaceutical field, especially solid preparations technology namely 3D printed tablets. This can support the purpose of personalizing medicine, especially related to drug dosages. Determination of dosage is made by designing tablets with certain volume using software to adjust the required dose. The purpose of this paper is to review several polymers that can be used in 3D printing with the fused deposition modeling as filament forming for the manufacture of 3D printed tablets and to analyze various types of drug release profiles. This review focuses on studying the characteristics found in several polymers, polylactic acid, polyvinyl alcohol, polycaprolactone, polyvinyl pyrrolidone, polyethylene oxide, ethylene vinyl acetate, ethyl cellulose, hydroxypropylmethyl cellulose, and hydroxypropyl cellulose in the form of thermoplastic, biodegradable, and mechanical properties so that they can applied in fused deposition modeling 3D printing technique. In addition, the drug release profile from 3D printed tablet is also studied. Research results show that polymers that can be used must have thermoplastic properties and are biodegradable. The polymers that have been mentioned can be used to form filaments for making 3D printed tablets. Drug release profile is very dependent on the polymer used on 3D printed tablets. Tablets made with this technology can be modified in both shape and size that affect the drug release profile from the matrix. 3D printed tablets has the potential to be developed using this method so that the goal of drug personalization can be realized."

"Tesis ini membahas mengenai pemetaan industri percetakaan di Indonesia dengan menggunakan Analisis klaster. dengan metode K-Means. Pada saat ini penyebaran industri percetakan di Indonesia tidak merata, sebagian besar terkonsentrasi di pulau Jawa (73.3%), belum adanya informasi mengenai industri percetakan, informasi yang ada hanya sebatas penyebaran 2585 percetakan berikut bentuk badan hukumnya sehingga kebutuhan logistik (produk cetak) yang tidak dapat terbagi secara merata di antara perusahaan percetakan yang ada.
Variabel yang digunakan dalam penelitian sebanyak 13 variabel, dengan menggunakan analisis faktor varibel direduksi menjadi 5 faktor. Hasil analisis klaster dengan metode K-means dibentuk sebanyak 3 klaster dimana faktor utilisasi mempunyai nilai p-value sebesar 0.620, lebih besar dari 0.05, artinya faktor utilisasi dari ketiga klaster relatif sama atau utilisasi antara klaster 1 tidak berbeda nyata dengan utilisasi di kedua klaster lainnya.
Klaster 1 terdiri dari 382 perusahaan yang merepresentasikan industri percetakan di Indonesia secara umum dimana semua nilai faktornya bertanda negatif yang artinya semua nilai faktor rendah atau berada dibawah Klaster 2 terdiri dari 4 perusahaan dengan faktor pendapatan lain dan investasi (7.75701) serta faktor asset (4.74713) tinggi, tetapi faktor terkait produksi rendah (-0.07193).Pada klaster 3 hanya faktor utilisasi saja yang rendah (-0.55112), hal ini menunjukkan perusahaan tidak efisien dikarenakan produktivitasnya yang rendah.
Hasil dari klaster yang terbentuk dibuat analisa SWOT sebagai salah satu dasar untuk rencana strategi pengembangan industri yang akan dilakukan. Pemerintah perlu kiranya untuk mengembangkan industri cetak secara lebih merata dan berkualitas.

This thesis discussed the mapping percetakaan industry in Indonesia by using cluster analysis. with K-Means method. At this time the spread of the printing industry in Indonesia is uneven, mostly concentrated in Java (73.3%), lack of information about the printing industry, there is only limited information dissemination following printing 2585 forms so that the logistics needs of its legal entity (print product) are not can be divided evenly among the existing printing company.
Variables used in the study as many as 13 variables, using a variable factor analysis is reduced to 5 factors. From the results of cluster analysis with K-means cluster method established as many as three clusters in which the utilization factor has a value p-value for 0620, greater than 0.05, meaning that utilization factor of the three clusters are relatively equal to or utilization of cluster 1 are not significantly different with the utilization in two other clusters.
Cluster 1 consists of 382 companies representing the printing industry in Indonesia is generally where all values are negative factors which means that all the factors are low or below-average population of clusters formed. Cluster 2 consists of 4 companies with other factors and investment income (7.75701) and high asset factor (4.74713), but low-production-related factors (-0.07193). In cluster 3 is only just a low utilization factor (-0.55112), but four factors others do not, it shows the company is inefficient due to low productivity.
Results from the cluster formed made a SWOT analysis as a basis for industrial development strategy plan will be done. Government is necessary to develop the print industry in a more equitable and quality.
