Performance Analysis of Regular and Horizontally Irregular Buildings in SMRF by Reviewing Torsional Stiffness, Center of Mass, and Center of Resistance due to Earthquakes
No full textIndonesia is a region located at the convergence of the Asian and Pacific earthquake belts, with Medan City, North Sumatra, being one of the areas with high seismic activity. Planning an earthquake-resistant structural system is crucial to prevent damage, especially in buildings with horizontal irregularity. This study aims to analyze the influence of horizontal irregularity in Special Moment-Resisting Frame (SMRF) systems on structural parameters such as the center of mass, center of rigidity, torsional stiffness, deflection, torsional angle, and column reinforcement requirements. Four building models were analyzed: rectangular, U-shaped, T-shaped, and L-shaped, with uniform area and column quantities. The analysis method used was response spectrum analysis with the assistance of MIDAS Gen Academic version 2023 software. The results show that the U-shaped building model exhibits the largest eccentricity, leading to greater torsion, torsional angle, and deformation. This results in increased internal forces in the columns and higher reinforcement requirements. This study provides important insights for designing irregular building structures to enhance their resistance to seismic loads.125 PagesSkripsi Sarjan
Nursing Care Management for Adolescent Girls with Menstrual Pain Through Finger Grasping Relaxation at Medan Selayang Subdistrict
No full textMenstrual pain (dysmenorrhea) is a common complaint experienced by adolescent
girls and can negatively impact quality of life and daily activities. This senior
practicum aims to manage nursing care for adolescents with menstrual pain
through the application of finger grip relaxation techniques as a non
pharmacological intervention. This nursing care involved three adolescent girls
aged 16–18 years, with assessments using the PQRST approach, the Numeric
Rating Scale (NRS) for pain, and observations of vital signs and facial expressions.
The intervention was conducted for 10–20 minutes daily over three days. Results
showed a significant decrease in pain scores from the first to the third day,
accompanied by reduced grimacing expressions and discomfort complaints. This
technique proved effective, with severe pain scores (score 8) decreasing to moderate
scores (score 5), was easy to apply, did not require additional tools, and could be
performed independently. In conclusion, finger-gripping relaxation techniques can
serve as a non-pharmacological therapy alternative for managing menstrual pain
in adolescents.99 PagesKarya Tulis Profes

Analysis Of Cadmium (Cd) Levels in White Cabbage (Brassica Oleracea L.) Using Wet Destruction Method With Atomic Absorption Spectrophotometry (AAS))
No full textFarmers in Namorambe District, Deli Serdang Regency, are still heavily dependent on the intensive use of inorganic fertilizers in their cultivation practices, including for white cabbage (Brassica oleracea L.). Excessive application of inorganic fertilizers can increase the risk of heavy metal accumulation, particularly cadmium (Cd), in plants. Cadmium is a toxic heavy metal that can accumulate in the human body and cause serious health problems when consumed over a long period of time. This study was conducted to determine the concentration of Cd in white cabbage cultivated in Namorambe District and to analyze the effect of different oxidizing agents in the closed wet digestion method on the accuracy of Cd analysis. The cabbage samples were first homogenized and then digested using two types of oxidizing solutions: pure HNO₃ and a mixture of HNO₃:HClO₄ at a ratio of 4:1. The Cd content was analyzed using Atomic Absorption Spectrophotometry (AAS). The results showed that the Cd concentration in white cabbage reached 0.2761 mg/kg using HNO₃ as the solvent and increased to 0.3619 mg/kg when using the HNO₃:HClO₄ (4:1) mixture. These values exceeded the maximum permissible Cd contamination limit set by SNI 7387:2009, which is 0.2 mg/kg. The HNO₃:HClO₄ (4:1) mixture produced a more effective digestion process, as indicated by the higher Cd concentration compared to digestion using HNO₃ alone. These findings indicate that white cabbage cultivated in the Namorambe area contains Cd levels exceeding the safe consumption limit. Therefore, strict monitoring of inorganic fertilizer use and regular evaluation of agricultural product quality in the region are urgently needed.53 PagesSkripsi Sarjan

History of the Taman Pendidikan Islam (TPI) in North Sumatera (1950-1966)
No full textThis research explores the historical development of Taman Pendidikan Islam (TPI) between 1950 and 1966. The study aims to: (1) examined the state of Islamic education in North Sumatra prior to the establishment of TPI; (2) investigated the motivations, processes, and progress of TPI's establishment in the region; and (3) evaluate TPI's contributions to the advancement of Islamic education in North Sumatra during the specified period. This research adopted sociologicals approach, employing the concepts of religious movements and Islamic education as analytical frameworks. The historicals method was used to encompassing the stages of source collection (heuristics), source evaluation (criticism), interpretation, and historical writing (historiography). The data sources include interviews with contemporaneous figures and TPI administrators, archives, official documents, TPI reports, correspondence, books, newspapers from this era, and other relevant literature. These sources were critically examined, interpreted, and reconstructed to form a coherent historical narrative. During the early of Indonesian independence, Islamic education in North Sumatra was still very limited, especially in plantation and rural areas. Meanwhile, urban areas such as Medan have developed quite a bit, especially through Islamic organizations such as Al-Washliyah and Muhammadiyah. The plantation areas in North Sumatra are quite large, and are the main foreign exchange earners. The workers are dominated by contract laborers from Java who eventually settled permanently. During the Dutch colonial period until the beginning of Indonesian independence, plantation workers lived in poverty and isolation, lacking in terms of education including religious education. Therefore, TPI, which was founded on May 1, 1950 by Rivai Abdul Manap Nasution, focused its activities on establishing madrasahs in the plantation areas of North Sumatra, Aceh, and Riau. In 17 months (May 1, 1950–September 1951), TPI succeeded in establishing 33 Madrasah Ibtidaiyah units in 31 plantations, involving 43 teachers and educating 2,899 students. In 1963, it developed into 160 Madrasah Rendah (Ibtidaiyah) TPI in plantations. TPI's contribution in North Sumatra includes the establishment of madrasahs in plantation areas, the implementation of Tri Karya Program (tabligh da'wah, education and culture, and social worship), increasing the religious understanding of plantation communities, developing teaching staff through PGAP and PGAA secondary schools, and improving the welfare of TPI teachers, whose salaries are equivalent to plantation office staff. This is a brilliant activity to increase educated human resources in North Sumatra & Aceh.205 PagesTesis Magiste
