Pendahuluan: Tingkat perkembangan dan maturasi seorang pasien tidak dapat diketahui secara pasti dari usia kronologis, dikarenakan adanya variasi waktu percepatan pertumbuhan pubertas pada setiap individu, maka perlu ditentukan usia biologisnya. Usia biologis ini dapat ditentukan dari usia tulang berupa kualitas tulang yang dapat dilihat dari ukuran densitas tulang. Radiograf panoramik dapat menilai kualitas kepadatan (densitas) tulang secara makrostruktur dan mikrostruktur. Penelitian ini menggunakan sampel perempuan karena perempuan cenderung kehilangan densitas mineral tulang lebih cepat daripada laki-laki. Tujuan penelitian ini yaitu menganalisis korelasi usia kronologis dengan densitas tulang pada radiograf panoramik pada pasien perempuan. Metode: Jenis penelitian ini adalah cross-sectional, dengan menggunakan analisis korelasi. Populasi penelitian menggunakan data primer dari seluruh radiograf panoramik pasien perempuan usia 5-35 tahun pada bulan Desember 2016-Januari 2017 di Rumah Sakit Gigi dan Mulut (RSGM) Universitas Padjadjaran dengan jumlah sampel 64 orang. Analisis densitas tulang trabekula mandibula dilakukan dengan menggunakan software ImageJ dengan Region of Interest (ROI) 4x4mm pada tepi distal foramen mentale mandibula. Hasil: Rerata ukuran densitas tulang trabekula pada kelompok usia 5-11 tahun 17,54%, kelompok usia 12-16 tahun 21,06%, kelompok usia 18-25 tahun 24,01%, dan kelompok usia 26-35 tahun 25,96% dengan hasil korelasi Pearson r = 0,827, dan nilai p=0,0001. Simpulan: Terdapat korelasi antara usia kronologis dengan nilai densitas tulang trabekula pada radiograf panoramik pasien perempuan, yaitu semakin bertambahnya usia kronologis maka nilai densitas tulang juga akan semakin meningkat sesuai dengan rentang usia penelitian 5-35 tahun.Kata kunci: Usia kronologis, densitas tulang, radiograf panoramik, software imageJ. ABSTRACTIntroduction: The level of development and maturation of a patient can not be known with certainty from chronological age, due to variations in the time of pubertal growth spurt in each individual, it is necessary to determine the biological age. This biological age can be determined from bone age in bone quality, which can be seen from the bone density measurement. Panoramic radiographs can assess the quality of bone density macrostructure and microstructure. This study used a female sample because female tend to lose bone mineral density faster than male. This study was aimed to analyse the correlation between chronological age and bone density on female patients’ panoramic radiographs. Methods: This research was cross-sectional with correlation analysis. The study population used was the primary data from all panoramic radiographs of female patients aged 5-35 years in December 2016-January 2017 at Universitas Padjadjaran Dental Hospital (RSGM Unpad) with a total sample of 64 people. Mandibular trabecular bone density analysis was performed using ImageJ software with a 4x4mm Region of Interest (ROI) on the mandibular mental foramen’s distal edge. Results: The mean size of trabecular bone density in the 5-11 years age group was 17.54%, the 12-16 years age group was 21.06%, the 18-25 year age group was 24.01%, and the 26-35 years age group was 25.96%; with the results of Pearson correlation r=0.827, and the p-value = 0.0001. Conclusion: There is a correlation between chronological age and the value of trabecular bone density on the panoramic radiograph of female patients, that is, the increasing of chronological age will also increase the value of bone density, according to the age range of the study (5-35 years).Keywords: Chronological age, bone density, panoramic radiographs, image-J software.

This research aims to determine the management procedures, incoming and outgoing mail in the Department ofPopulation and Civil Registration Tanah Datar. This research was a descriptive research with qualitative methods.The types of data used in this study were a primary data and secondary data. Data collection techniques used:observation, interviews, and documentation. Technique authenticity of data used triangulation techniques.Determination of informants of this research used purposive sampling technique. The results of this research weremanagement procedures, incoming and outgoing mail was not optimal for the management of the mail was not inaccordance with the guidelines used by the Department of Population and Civil Registration Tanah Datar. Obstaclesencountered in the management letter that was often receive supplementary letter, the rediscovery of the archiverequires a long time, and archival storage room was not yet available. From these results Office of Population andCivil Registration Tanah Datar, it is advisable to carry out management activities in accordance with the letter of theguidelines have been used, as well as an effective complementary equipment in the rediscovery of the archives, andheld a special space for archive storage.Keywords: Procedures, Inbox, and Outgoing Mail

This research investigates the comparison between Batusangkar sub-dialect and Lintau Buo sub-dialect, which focuses on phonetic and phonological aspects. The aim of this study is to identify the types of sound changes that occur between two sub-dialects in the same language from phonetic and phonological aspects. This research used a descriptive method. The researcher used elicitation techniques in conducting interviews to collect data from each informant. The results of this study indicate that there are 13 sound changes, which are divided into 5 vowel changes, that are [a] to [əʊ], [ɪ], [ə], and [ɑ:] to [ɔ:]. Then, 4 consonant changes, that are [k] to [ɳ], [r] to [w] and [ɰ], and [t] to [m], and 4 diphthong changes, that are [ɪa] to [ɪə] and [ɪʊ], [ʊa] to [ʊə] and [ʊ]. In addition, there are sound changes caused by phonological processes; assimilation, dissimilation, insertion, and deletion. Furthermore, there are several words that have full vocabulary changes. The results show that the pronunciation between the two sub-dialects is different. The significant changes occurred when the word in sound [a] in Batusangkar sub-dialect is changes to [o] in Lintau Buo sub-dialect and the word, which have a phonological process that is deletion.
