    It is necessary to prepare for the increasing crime rate of household theft with a modern home security system that allows customers to monitor home security remotely. This can be accomplished by replacing the standard lock with a solenoid door lock, which is more difficult to duplicate and reduces the likelihood of theft when the house is unoccupied. The Authors developed a three-tiered home security system prototype that includes fingerprint, the RFID, and keypad biometric sensors. The device's finished prototype was tested ten times after it was designed. The Arduino Uno microcontroller, which also serves as the door-locking mechanism, turns on the door-lock solenoid. When authentication is successful, someone will be granted access to the door. The preliminary findings indicate that the fingerprint. The fingerprint sensor's ability to read fingerprints in 3.7 seconds on average demonstrates its effectiveness. Second, the RFID sensor detects the e-KTP, and the RFID scans the card in an average of 2.4 seconds. The third keypad contains the password for unlocking the door. After ten repetitions, the experiment input yields an average time of 3.66 seconds. Opening a door with a 3-level multi-sensor typically takes 9.8 seconds. In this study, the installation of each sensor is notified via a GSM SIM800L module, allowing customers to monitor security remotely

    ABSTRACT This study aims to determine the meaning of smoking behavior. Symbolic interaction theory explains subjective meaning as the basis for action. The symbolic interaction perspective contains the same thoughts as social action theory about the subjective meaning of human behavior, social processes and pragmatism. This means that humans (in smoking behavior) act based on the meaning they understand. This study uses symbolic interaction theory which explains the behavior of the meaning understood by smokers as seen from the aspects of mind, self, and society. This study uses qualitative methods by using a constructivism approach. In-depth interviews data collection technique used to get information from lecturer’s smokers at Islamic University of Riau which was determined by purposive sampling technique. The data analysis technique used is qualitative data analysis. The results of this study show that the anomaly meaning in smoking behavior is reflected based on the meaning that understood by smokers about smoking behavior. The meaning of smoking based on “Mind” is a negative activity, positive life habits, entertainment, symbol of creativity, hard work, symbol of friendship and an economic symbol. The meaning of smoking based on “Self” means dependence, self-confidence, and economic stability. While, based on the concept of society, smoking is a behavior caused by the social interaction of the smoker with the community in the smoker's environment in the family, general public, work environment, and past experiences.Keywords: anomaly meaning, lecturer, smoking behavior, symbolic interactionism  ABSTRAK Penelitian ini bertujuan untuk mengetahui makna perilaku merokok. Teori interaksi simbolik menjelaskan makna subjektif sebagai dasar tindakan. Perspektif interaksi simbolik mengandung pemikiran yang sama dengan teori tindakan sosial tentang makna subjektif dari perilaku manusia, proses sosial dan pragmatismenya. Artinya  manusia (dalam perilaku merokok) bertindak berdasarkan makna yang dipahami dalam diri mereka. Penelitian ini menggunakan teori interaksi simbolik yang menjelaskan perilaku dari makna yang dipahami oleh perokok yang dilihat dari aspek mind, self, dan sosiety. Penelitian ini menggunakan metode kualitatif dengan menggunakan pendekatan konstruktivis. Teknik  pengumpulan  data yang dilakukan adalah wawancara mendalam kepada informan penelitian dosen perokok di lingkungan Universitas Islam Riau yang ditentukan dengan Teknik purposive sampling. Teknik analisis data yang digunakan adalah analisis data kualitatif. Hasil penelitian ini menunjukkan bahwa terdapat anomali makna dalam perilaku merokok yang direfleksikan berdasarkan makna yang dipahami oleh para perokok tentang perilaku merokok itu sendiri. Makna merokok berdasarkan Mind merupakan aktivitas negatif, kebiasan Positif, sarana hiburan, simbol kreativitas kerja keras, simbol pergaulan dan simbol ekonomi. Kemudian makna merokok berdasarkan Self bermakna ketergantungan, percaya diri, dan kemapanan ekonomi. Selanjutnya berdasarkan konsep society merokok adalah perilaku yang disebabkan oleh interaksi sosial perokok dengan masyarakat yang ada di lingkungan perokok. Hasil penelitian ini menunjukkan bahwa interaksi sosial perokok yang membentuk makna merokok terjadi di lingkungan keluarga, masyarakat umum, lingkungan kerja, dan pengalaman masa lalu.Kata Kunci: anomali makna, dosen, perilaku merokok, interaksi simboli

    This case report describes a complex radical 3D-Conformal Radiotherapy treatment planning, dosimetric issues and outcome of definitive treatment of un-resectable carcinoma of the vulvar in a 42-year old lady. The patient presented with large fungating mass of the vulva which was biopsy confirmed as Keratinizing Squamous Cell Carcinoma. Further staging investigation revealed locally advanced disease (T4), with bilateral inguinal lymph nodes involvement. There is no systemic metastasis or intra-pelvic nodes. The patient was seen by Gynae-Oncology team and the disease was deemed un-resectable without significant morbidity. She was treated to a total dose of 64.8Gy in 36 fractions over 7 weeks with concurrent weekly Cisplatinum in 2 phases. 3D-Conformal radiotherapy technique using the modified segmental boost technique (MSBT, large PA and small AP photon fields with inguinal electron matching) was used. TLD chips were used for in-vivo dose verification in phase 1 and 2 of the treatment. At completion of planned radiotherapy, patient had a complete clinical response, grade 2-3 skin toxicity, grade 2 rectal toxicity, and grade 2 dysuria Vulval Squamous Cell Carcinomas are very radiosensitive tumours and the skills of the treating Radiation Oncologist, Dosimetrists, Physicist, Radiation Therapist and also nurses is of foremost importance is ensuring good clinical outcomes

    The challenge of rural life nostalgia: barriers in redevelopment of Malay Reserve Land (MRL) in Klang Valley

    The development of Malay reserve land is a nationwide issue which can be overcome through better understanding of the existing barriers. While many barriers have been examined, the challenges relating to land owner expectations and preferences has not been thoroughly examined. Using Kg Sungai Penchala in the capital city Kuala Lumpur as a case, this research used a structured interview survey of 258 respondents representing both owners and tenants. Statistical analysis demonstrates that majority of the land owners (individuals) rejected the idea to further develop the land. The land owners preferred to maintain the village status quo and they were satisfied with the current development level in the village. Only a minority of respondents agreed that the land should be developed and instead perceived that re-development of this Malay Reserve Land of Kg Sungai Penchala would be able to raise their quality of life. The restriction is much preferred by the land owners who preferred the current style of village living. Thus, immediate re-development of the area is not warranted and the preference of the land owners represents a strong barrier
