Abstract

Di dalam penilaian prestasi siswa, dibutuhkan banyak hal yang akan dilakukan untuk membuat sebuah pengujian dari masing-masing siswa, sehingga dapat dihasilkan nilai akhir yang dapat dijadikan penilaian prestasi siswa. Dalam hal ini, melakukan mengurutan data pasti selalu dilakukan, terutama dibidang pendidikan seperti sekolah. Biasanya dalam melakukan pengurutan data berupa prestasi siswa di sekolah membutuhkan waktu dan beberapa kriteria yang telah ditentukan oleh pihak sekolah, hal ini sering membutuhkan waktu yang begitu lama karena banyaknya jumlah siswa dan kelas dari dari sebuah sekolah, terutama di sekolah swasta. Untuk itu, dalam melakukan pengurutan data, bisa juga menggunakan sebuah algoritma atau metode yang dapat mempermudah proses sebuah penilaian prestasi siswa. Algoritma bubble sort merupakan beberapa dari metode yang dapat digunakan untuk melakukan pengurutan data. Algoritma ini dapat melakukan perbandingan data dari yang maksimal ke minimal maupun sebaliknya, sehingga ketentuan dari nilai yang ingin diperoleh dapat langsung ditentukan sesuai dengan kriteria yang diinginkan. Dengan menggunakan Algoritma Bubble sort, dapat mempermudah dan meringankan tugas guru dalam melakukan pengurutan data prestasi dari siswa, sebelum data tersebut dicetak kedalam raport siswa. Hasil akhir dari penggunakaan algoritma ini bisa dijadikan sebagai patokan bagi seorang guru untuk membuat laporan akhir dari penilaian prestasi siswa.

Abstract

SINTESIS DAN KARAKTERISASI MICROSPHERE BERBASIS POLIMETIL META AKRILAT (PMMA). Telah dilakukan studi tentang pengaruh konsentrasi PMMA terhadap bentuk dan ukuran microsphere dengan menggunakan scanning electron microscope (SEM). Sintesis microsphere dilakukan dengan metode pengadukan dan evaporasi larutan dan suatu sistem emulsi. Proses emulsifikasi dilakukan dengan mencampurkan larutan PMMA di dalam pelarut kloroform dengan variasi konsentrasi 1, 4, 8 dan 16 % (b/b) kedalam larutan PVA di dalam pelarut aquades dengan konsentrasi 1 % (b/b). Hasil yang diperoleh menunjukkan bahwa ukuran dan bentuk microsphere dipengaruhi oleh konsentrasi larutan polimer. Pada konsentrasi PMMA terlalu rendah (1% b/b) atau konsentrasi PMMA terlalu besar(16% b/b) diperoleh ukuran microsphere beragam dari 20 - 200 µm, sedangkan pada konsentrasi polimer PMMA 4% dan 8% (b/b) diperoleh ukuran microsphere yang relatif seragam sebesar 20 µm. Analisis ketahanan panas dengan menggunakan differental thermal analyzer (DTA) diperoleh titik gelas microsphere berbasis PMMA, Tg berkisar pada 256,5 °C dan entalpi gelas ∆H = 1,476 J/g. Sedangkan suhu leleh Tm = 275,8 oC dengan entalpi leleh ∆H = -12,72 J/g dan suhu dekomposisi Td = 3 73,4 oC dengan entalpi dekomposisi ∆H =-27,86 J/g.

Abstract

Electricity energy needs in Bali have increased annually by 135,2 GWh, as a result, the State-Owned Electrcity Company (PLN) is being required to add new power plants or the addition of transformer to serve load side fedeers. New transformer have been added to Padang Sambian substation and the reconfiguration of Padang Sambian feeders. The reconfiguration causes the feeder impedance value to change, thus affecting the protection system such as Over Current Relay (OCR) and Ground Fault Relay (GFR). Calculation of current setting and OCR and GFR relay work time can minimize the interference that occurs. The amount of short circuit current that occurs in Padang Sambian fedeers was calculated to determine the value of relay settings. The result of the analysis showed that the OCR current setting value for the incoming side of 0,91 A with Time Multiplier Setting (TMS) was 0,2 SI and OCR on the outgoing side of 2,063 A with TMS of 0,161 SI. The value of current setting for the incoming GFR was 0,01 A with TMS of 0,27 SI and the setting value of the GFR current on the outgoing side was 0,16 A with TMS of 0,106 SI. The result of Electrical Power System Analysis (ETAP) simulation obtained an OCR and GFR coordination curve that did not intersect the Time-Curve Current (TCC) characteristic. This shows that coordination runs well and meets sensitivity, reliability, selectivity and speed requirements.

Abstract

Tourism potential in South Bogor spreads in several villages, including the Pamoyanan, Empang, and Cikaret Village. Kompepar is driving tourism groups that take part in the management of tourism in South Bogor. The tourism in the area has not been fully managed due to the ability of tourism management still minimal. Therefore it is necessary to empowering Kompepar through training identification of potential tourism travel, tour packaging, and making proposals for procurement activities/tour supporting infrastructure. Models of activities carried out by training, mentoring, and on going monitoring, through tutorials, discussion, lab (field surveys and interviews) as well as presentations. The training divided in to three steps, with the strategy implemented in door training (in class) and mobile partners to target areas. The results show the training participants are able to make an identification of potential training products such as travel, tour packages, and a simple proposal. The quality of training results have not shown good results. This constrained the ability of the participants were minimal basis for knowledge about and some of the participants have not mastered basic computer. Therefore the process of assisting and monitoring is done continuously and in parallel, for each group is accompanied by one or two instructors. Empowerment followed by media online optimization via engagement KIM South Bogor, by way of training and mentoring to load the identification of potential sites and travel packages to www.wisatabogorselatan.com. Empowerment comes with mentoring and facilitating Kompepar in propose the proposals to the relevant stakeholders.

Abstract

Oral lichen planus (OLP) is a chronic inflammatory disease that affects the mucous membrane of the oral cavity. It is a T-cell mediated autoimmune disease in which the cytotoxic CD8+ T cells trigger apoptosis of the basal cells of the oral epithelium. Linear Gingival Erythema (LGE) is a progressive disease described in HIV-positive patients and is considered to be an early stage of necrotizing periodontitis. Objective of this case report is to help clinicians to recognize and distinguish OLP lesions from other lesions that have similar appearance such as LGE and give a proper treatment for the oral lesions. We reported a case on a 49-year-old female that was referred to Oral Medicine Department from Periodontology Department with the diagnosis of ANUG and differential diagnosis of Linear Gingival Erythema. On clinical examination, we found Wickham’s striae on buccal mucosa and the edge of the lesion. The patients was then  diagnosed with Oral Lichen Planus. The patient was treated with sistemic and topical corticosteroid. After 8 weeks of treatment the patient was fully recovered. OLP is seen clinically as reticular, papular, plaque-like, erosive, atrophic or bullous types. Intraorally, the buccal mucosa, tongue and the gingiva are commonly involved although other sites may be rarely affected. Erosive or atrophic types that usually affect the gingiva usually show concomitant reticular form. LGE is limited to the soft tissue of periodontium and characteristically appears as an erythematous linear band that extends approximately 2 – 3mm from the free gingival margin. OLP lesions may have similarity with other oral lesions such as LGE. It is important for clinicians to recognize the lesions and choosing the proper treatment for the diseasesKeyword: Oral Lichen Planus, Linear Gingival Erythema, HIV, Corticosteroid
