The growth has transformed green open space gradually to commercial uses. Along with that, there has also been a social shift in Jakarta and its satellite cities. Citizen maximizes their earnings from working at the office and trading in order to maintain (and upgrade) their welfare. As a result, their leisure time (including enjoying the park) worn off. Taman Spot Budaya Dukuh Atas (TDA) has been a Jakarta provincial government’s solution to such issues, i.e decreasing number of parks and open spaces, and the limited time available to enjoy them. A review in user appreciation, adaptation to current and upcoming trends, and its compatibility as public space and third space will be a benchmark for modern public space development. This study applies a qualitative research approach with a case study method. TDA proves to be one of the people’s option to hang out at public space, especially in a crowded city district. TDA also fulfilled public space, third space, and Jakarta government’s goals. But better maintenance and improvement are needed to ensure its sustainability. The concept of public space that can be enjoyed in a short time are expected to be replicated to several other crowd points in Jakarta and other major cities in the future. Keywords: Dukuh Atas; green open space; user appreciation; modern public space AbstrakSejak akhir 1980-an bisnis properti berkembang pesat di Indonesia, khususnya di Jakarta. Perkembangan ini mengkonversi lahan-lahan terbuka hijau menjadi lahan dengan fungsi komersil. Seiring perkembangan tersebut, terjadi pula pergeseran sosial di Jakarta dan di kota-kota penyangganya. Masyarakat memaksimalkan perolehannya dari bekerja di kantor atau berdagang demi menjaga (dan meningkatkan) kesejahteraannya. Akibatnya, waktu luang untuk rekreasi (termasuk menikmati taman) menjadi berkurang. Taman Spot Budaya Dukuh Atas (TDA) adalah salah satu solusi Pemda DKI Jakarta dalam memberikan fasilitas ruang terbuka, sekaligus melayani kategori warga kota tersebut. Peninjauan apresiasi pengguna, adaptasi dengan kecenderungan yang ada, dan kesesuaiannya sebagai ruang publik serta ruang ketiga menjadi tolok ukur bagi alternatif pengembangan ruang publik modern. Penelitian ini menggunakan pendekatan penelitian kualitatif, dengan metode studi kasus. TDA dapat menjadi pilihan masyarakat untuk menikmati ruang publik, khususnya di pusat kota. TDA sendiri sudah memenuhi kriteria sebagai ruang publik dan ruang ketiga, serta sudah sesuai dengan tujuan awal Pemda DKI.

In high-rise buildings that are more than or equal to 60 floors in the current era, systems are used in the structure of the building. The function of the Belt Truss is to reduce the deflection that occurs in the building by converting the building's overturning moment into the axial force of the exterior column. The Belt Truss structure itself can use reinforced concrete structures and steel structures. Because the Belt Truss structure is an innovation in the world of structural engineering, the parameter values for earthquake loads are not listed in the applicable Building Planning Standards. The standard for earthquake-resistant building regulations requires the parameters of Response Modification Factor (R), Overstrength Factor (Ωo), and Deflection Magnification (Cd) for determining earthquake loads. Because the parameters on the Belt Truss structure are not listed in the Standard for Earthquake Resistant Building Regulations, a study of the earthquake load parameters on the Belt Truss structure was carried out. The method used in this research is a literature study using Pushover Load Analysis according to ATC - 40 and FEMA 356. Keywords: Belt Truss, Dual System; ATC – 40; FEMA 356; Response Modification Factor (R); Overstrength Factor (Ωo); and Deflection Magnification (Cd) AbstrakDalam aplikasi rekayasa struktur gedung, batasan defleksi bangunan atau interstory drift adalah masalah penting. Pada bangunan tinggi yang lebih dari atau sama dengan 60 lantai pada era sekarang sudah menggunakan sistem pada struktur bangunan tersebut. Fungsi dari Belt Truss tersebut berguna untuk mengurangi defleksi yang terjadi pada bangunan dengan mengkonvesi momen guling bangunan menjadi gaya aksial kolom eksterior. Struktur Belt Truss sendiri materialnya bisa menggunakan struktur beton bertulang dan struktur baja. Karena struktur Belt Truss merupakan inovasi pada dunia rekayasa struktur, maka nilai parameter beban gempa tidak tercantum pada Standar Peraturan Perencanaan Bangunan yang berlaku. Standart Peraturan Bangunan tahan gempa diperlukan parameter – parameter Faktor Modifikasi Respon (R), Faktor Kuat Lebih (Ωo), dan Perbesaran Defleksi (Cd) untuk penentuan beban gempa. Dikarenakan parameter pada struktur Belt Truss tidak tercantum pada Standar Peraturan Bangunan Tahan Gempa, maka dilakukan penelitian parameter-parameter beban gempa pada struktur Belt Truss tersebut. Metode yang digunakan dalam penelitian ini adalah studi literatur dengan menggunakan analisa Beban Dorong Pushover Analysis sesuai ATC - 40 dan FEMA 356.","PeriodicalId":202016,"journal":{"name":"Jurnal Muara Sains, Teknologi, Kedokteran dan Ilmu Kesehatan","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125123128","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 results of examining LDL must be precise and accurate, but direct LDL examination (LDL-Direct) is quite expensive to do in a place with limited facilities so various experiments are carried out to get LDL formula (LDL-Cal) that is appropriate than formula commonly used, Friedewald formula. The aimed of this study was to determine the correlation between LDL cholesterol from calculation a number formulas with direct LDL cholesterol in order to obtain the best formula to be applied in laboratory of Lubuk Sikaping Hospital. This research was conducted on 75 patients who did lipid profile examination in laboratory of Lubuk Sikaping Hospital, who meet the inclusion criteria. Examination of total cholesterol, HDL, LDL and triglycerides were carried out by enzymatic methods on clinical chemistry analyzer. LDL cholesterol also calculated by several formulas namely Friedelwald formula (TC- (TG/5) -HDL), Chen formula (90% nonHDLC-10% TG), Anandaraja formula (0.9 TC- (0.9 TG/5) -28), Puavilai formula (TC-HDLC-TG/6), Vujovic formula (TC-HDLC-TG/3), and Cordova formula (3/4 (TC-HDLC.) Bland & Altman plot was used to compare the calculated LDL cholesterol level of each formula with the direct LDL. The mean LDL levels were 136.41 (35.92); 116.64 (32.72); 117.03 (30.83); 121.95 (32.79); 121.83 (33.23); 96.84 (32.47); 109.97 (28.24) for Direct, Friedelwald, Chen, Anandaraja, Puavilai, Vujovic, and Cordova respectively. Based on the Bland & Altman Plot, the calculation of LDL cholesterol from the Chen formula has the best compatibility with LDL-Direk with the mean difference of 19.3867 ± 19.0489 mg / dl at triglyceride levels <400 mg / dl, so it can be applied at RSUD Lubuk Sikaping with limited facilities. Keywords: LDL Cholesterol; LDL-Direct; LDL-CalAbstrakPeningkatan kadar kolesterol merupakan penyebab utama penyakit jantung koroner. Hasil pemeriksaan kadar LDL serum harus tepat dan akurat, namun pemeriksaan kadar LDL secara langsung (LDL-Direk) cukup mahal untuk dilakukan di tempat dengan fasilitas terbatas sehingga dilakukan berbagai percobaan untuk mendapatkan formula perhitungan LDL (LDL-Cal) yang lebih tepat dibandingkan formula yang telah umum digunakan yaitu formula Friedewald. Penelitian ini bertujuan untuk mengetahui kesesuaian antara kolesterol LDL hasil perhitungan sejumlah formula dengan kolesterol LDL direk sehingga diperoleh formula perhitungan terbaik untuk dapat diterapkan di laboratorium RSUD Lubuk Sikaping. Penelitian ini dilakukan terhadap 75 orang pasien yang melakukan pemeriksaan profil lipid lengkap ke Laboratorium RSUD Lubuk Sikaping. yang memenuhi kriteria inklusi. Pemeriksaan kolesterol total, HDL, LDL dan trigliserida dilakukan dengan metode enzimatik pada alat kimia klinik otomatis. Untuk kolesterol LDL juga dihitung dengan beberapa rumus yaitu formula Friedelwald (TC-(TG/5)-HDL). formula Chen (90%nonHDLC-10%TG), formula Anandaraja (0.9 TC- (0.9 TG/5)-28),","PeriodicalId":202016,"journal":{"name":"Jurnal Muara Sains, Teknologi, Kedokteran dan Ilmu Kesehatan","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114851990","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}
