Abstract

ABSTRAK  Telah dilakukan pengukuran distribusi dan konsentrasi asap partikel dari hasil penyalaan GPG yang dilakukan di Lap TMC - Puspiptek Serpong. Alat yang digunakan dalam pengukuran baik besar, distribusi dan konsentrasi partikel adalah menggunakan LightHouse (LH) yang bisa menampilkan secara langsung dalam layar monitor alat tersebut. Yang secara langsung terbaca dalam monitoring LH adalah besar partikel dan jumlah partikel per satuan volume (m3). Kisaran alat pengukur partikel LH bisa mengukur terkecil 0.3 mikron hingga 5 mikron dengan rincian 0.3, 0.5, 1.0, 2.5, dan 5 mikron. Light House (LH) adalah satu satunya alat yang biasa digunakan untuk pengukuran udara dan lingkungan dari Laboratorium Aerosol, PTKMR BATAN. Telah dilakukan pengukuran partikel dari asap GPG (Ground Particles Generator) sebanyak 21 kali sampling. Sekali pegambilan sampling asap diperlukan waktu sebanyak 5 menit dan pengukuran udara dalam wadah sampling tersebut juga diperlukan waktu sekitar 5 menit. Selain pengukuran dengan menggunakan LH, juga dilakukan pengukuran dengan menggunakan Impaktor Kaskade Type Anderson dengan 12 tingkat yang memungkinkan pengukuran dari 0.1 mikron hingga 9 mikron. Waktu yang diperlukan cukup lama, yaitu antara pukul 13.15 hingga 18.15 WIB yaitu 5 jam. Impaktor tidak bisa langsung terbaca hasil pengukuran partikelnya namun harus di proses kemudian di kondiskan serta dilakukan penimbangan partikel yang mengendap di setiap tingkatan, sehingga bisa diketahui distribusi partikel tersebut setiap tingkat dari 0.1 mikron hingga partikel terbesar yaitu 9 mikron. Hasil sementara dari pengukuran menggunakan LH dari sebanyak 21 sampel adalah untuk partikel 0.3 mikron memiliki jumlah partikel terbesar mencapai 495.466.815/m3 atau 495 partikel/cm3 asap dan terkecil sebanyak  51.767.763/m3 atau 52 partikel/cm3 asap. Sementara, untuk partikel yang terukur 0.5 mikron terbanyak mencapai 8.969.923/m3 atau 9 partikel/cm3 asap dan terkecil 84.755.200 partikel/cm3 atau 85 partikel/cm3. Sedangkan, partikel yang terukur 1.0, 2.5 dan 5.0 mikron di LH tidak terpantau atau tidak ada sama sekali alias Nol (skala 1 cm3). Tampak puncak distribusinya diperkirakan kurang dari 0.3 mikron (antara 0.1 – 0.05 mikron), sebagai “tail” kanan distribusi (jika dianggap normal) adalah 0.5 mikron. Perkiraan tersebut akan di buktikan dengan menggunakan Impaktor yang bisa mengukur partikel terkecil 0.1 mikron.    ABSTRACT  Measurement of Concentration Distribution and smoke particles from the ignition GPG conducted in TMC-Lab Puspiptek Serpong. Measurement tool used in both large, the distribution and concentration of particles is using Light-House (LH) which can display directly in the device monitor screen which is directly readable in monitoring large particles and LH is the number of particles per unit volume (m3). LH range of gauges can measure the smallest particles 0.3 microns to 5 microns with the details 0.3, 0.5, 1.0, 2.5 and 5 microns. Light House (LH) is the only tool used to measure air and environment of the Aerosol Laboratory, PTKMR BATAN in Jakarta. Have performed measurements of the smoke particles GPG (Ground Particles Generator) as much as 21 times the sampling. Once pegambilan sampling smoke take as many as 5 minutes and air measurements in the sampling container also takes about 5 minutes as well. In addition to measurements by using LH, also be measured by using the cascade Impaktor Type Anderson with 12 levels that allow measurement of 0.1 microns to 9 microns. It takes quite a long time, which is between 13:15 to 18:15 hrs ie 5 hour. Impaktor can not directly read the results of measurements of the particles but must be in process later in kondiskan and sediment particles weighing is done at every level, so they can know the distribution of particles of 0.1 microns each level until the largest particles is 9 microns. Interim results of measurements using as many as 21 samples of LH is for 0.3 micron particles have the greatest number of particles reaching 495 partikel/cm3 495.466.815/m3 or as much smoke and the smallest 52 partikel/cm3 51.767.763/m3 or smoke. While, for the measured particles 0.5 microns or 9 the highest reaches 8.969.923/m3 partikel/cm3 smoke and smallest partikel/m3 84,755,200 or 85 partikel/cm3. Whereas, particles measured 1.0, 2.5 and 5.0 microns in LH is not monitored or none at all, aka Zero. Looks peak distribution estimated to be less than 0.1 microns, as the "tail" distribution right (if it is considered normal) is 0.5 microns. The estimate will be proved by using Impaktor that can measure the smallest particles of 0.1 microns.

Abstract

This research discusses the effect of providing occupational therapy on fine motor development in autistic children at ADNI Kindergarten in Surabaya. The aim of the research is to see the effect of providing occupational therapy on the development of fine motor skills in autistic children at ADNI Surabaya Kindergarten. Occupational therapy is a therapy used for autistic children and can also be applied to children/adults who experience autism, speech delays, developmental disorders and other growth and development delays. Occupational Therapy aims to help children who experience problems with their fine motor skills. This therapy can be used as an option to try to improve children's physical and mental abilities to take part in activities that involve children's gross and fine motor skills so that children can be independent and can develop and be accepted in society. This research will be carried out at the ADNI Surabaya Kindergarten. The methodology used is a quantitative method with a Pre-Experimental design. Based on the results of the analysis, the change in the mean concentration value before and after being influenced by Occupation showed that the Pre-test value was mean = 1.38 and the Post-test value experienced a change, namely mean = 1.50. Meanwhile, the statistical test results obtained a p value of 0.024, which means that there is an influence of Occupational Therapy on the development of Fine Motor in Autistic children at ADNI Surabaya Kindergarten in 2024.

Abstract

This study aims to analyze the influence of Islamic financial literacy and bank image on customer decisions in using mortgage financing products at Bank Tabungan Negara (BTN) KC Syariah Palembang. Islamic financial literacy plays an important role in increasing public understanding of Islamic banking products, which will influence decisions in choosing financial products. In addition, a positive bank image also contributes to building customer trust in the services offered. This study uses a quantitative method with the Structural Equation Modeling-Partial Least Squares (SEM-PLS) approach. Data were collected by distributing questionnaires to BTN KC Syariah Palembang customers who use mortgage financing products. The results of the study indicate that Islamic financial literacy and bank image have a positive and significant effect on customer decisions. The implications of this study indicate that increasing Islamic financial literacy and strengthening bank image can be an effective strategy for Islamic banks in increasing the number of users of Islamic-based mortgage products. Therefore, a broader Islamic financial education program is needed as well as improving the quality of services and transparency in Islamic banking operations to build customer trust and loyalty..

Abstract

This article explores a critical perspective on epistemology that has long been influenced by Western-centric biases, aiming to uncover its inherent discriminatory aspects. Employing a literature-based approach, the discussion centers on two primary concerns. First, the exclusionary nature of Western epistemology is inseparable from the ideals of modernity, which emphasize progress and innovation. These characteristics often marginalize alternative knowledge systems rooted in traditional or indigenous communities. Second, the discourse of development operates as a mechanism to perpetuate Western epistemological dominance, serving as a justification to reassert control over nations in the Global South or former colonies. The article concludes by emphasizing the importance of fostering a critical mindset among scholars, encouraging openness to diverse epistemological frameworks that reflect local contexts, without entirely dismissing the scientific traditions of the West.
