Lombok Island is one of the earthquake-prone areas, located between two earthquake generators. Based on these conditions, it is expected that construction in earthquake-prone areas can meet the standards. Shear walls are one of the earthquake-resistant structural systems used to resist lateral forces. Three alternative shear wall shapes will be analyzed using the numerical method: the L, I, and T shapes. The types of loads to be analyzed are dead loads, live loads, and earthquakes. Drawing from the findings of the conducted analysis, it is discovered that the most effective shear wall position in resisting lateral forces is the shear wall located at the corner of the building, based on the values of the drift that occur in the x and y directions. In addition, increasing the number of shear walls can reduce the internal forces that structural components experience. The optimum drift value is obtained from alternative 1, the L-shaped shear wall (elbow), with a drift value of 0.000495 mm in the x direction and 0.000883 in the y direction.

Literacy and numeracy programs play a crucial role in improving education quality, especially at the elementary school level. This study aims to optimize literacy and numeracy programs through a structured mentoring approach at SDN Grujugan Larangan, Larangan Luar Village, Larangan Subdistrict, Pamekasan Regency. The research method used is action research with qualitative and quantitative approaches. The qualitative approach is used to understand teachers' and students' perceptions of the mentoring program, while the quantitative approach is applied to measure the improvement in students' literacy and numeracy skills after participating in the program. The results indicate that structured mentoring significantly enhances students' literacy and numeracy skills, as evidenced by the increased average scores in reading, writing, and arithmetic. Furthermore, active teacher involvement in the mentoring process contributes to the program's success. Thus, implementing a structured mentoring program can be an effective model to improve the quality of primary education in rural areas.

Ikterus atau jaundice merupakan perubahan warna menjadi kuning yang terjadi pada neonatus atau bayi baru lahir pada sklera mata, mukosa dan kulit karena peningkatan kadar bilirubin dalam darah. Dampak dari faktor penyebab ikterus pada bayi adalah apabila kadar bilirubin meningkat secara berlebihan dan tidak dikeluarkan tubuh, bayi lebih berisiko menjadi tuli, terkena lumpuh otak (cerebral palsy), kerusakan otak (kernikterus) dan bahkan kematian. Faktor-faktor yang menyebabkan terjadinya ikterus bisa berasal dari faktor maternal, perinatal dan neonatal. Kejadian Ikterus neonatorum di Rumah Sakit Universitas Mataram menempati urutan kedua setelah BBLR. Tujuan penelitian untuk mengetahui gambaran faktor penyebab kejadian ikterus pada bayi di Ruang NICU Rumah Sakit Universitas Mataram. Desain penelitian ini adalah deskriptif. Populasi adalah seluruh bayi dengan usia 0-28 hari dengan teknik pengambilan sampel menggunakan purposive sampling. Hasil penelitian ini didapatkan faktor yang menyebabkan ikterus neonatorum pada faktor maternal dengan umur kehamilan aterm (<37 minggu) sebanyak (55,9%). Faktor perinatal yaitu jenis persalinan dilakukan dengan tindakan SC (Section Caesarea) sebanyak (58,8%). Faktor neonatal memiliki berat bayi lahir rendah (BBLR) (52,9%). Diharapkan orang tua dapat mengetahui tanda dan gejala sedini mungkin anak yang mengalami ikterus dan segera membawa ke fasilitas pelayanan Kesehatan untuk meminimalisir terjadinya komplikasi ikterus.

Ring of Fire and at the intersection of three tectonic plates. Efforts are needed to minimize earthquake damage, one of which is the use of a base isolator system. This study aims to determine the effect of using High Damping Rubber Bearing (HDRB) with a diameter of 800 mm on the behavior of reinforced concrete structures in tall buildings under seismic loads. The research location is the 7-story Sapadia Hotel building in the city of Mataram. The research is conducted by analyzing a 3D model of the fixed base structure and the base isolator structure using numerical analysis. The results show an increase in the base displacement of the base isolator structure by 59% in the x-direction and 44% in the y-direction, while the inter-story displacement decreases by 36% in the x-direction and 69% in the y-direction. The use of base isolators can reduce the shear force by 35% in the x-direction and 15% in the y-direction. Based on the pushover analysis, the roof displacement values for the fixed base and base isolator structures are 0.159 m and 0.129 m respectively. These values can be used to determine the structural performance level according to ATC-40. The maximum drift value for the fixed base structure is 0.0055 m. For the base isolator structure, the maximum drift value is 0.0044 m, categorized as Immediate Occupancy (IO). This value can be used to determine the performance level of the structure based on ATC-40. The maximum drift value of the fixed base structure is 0.0055m. While in the base isolator structure, the maximum drift value is 0.0044 m which is included in Immediate Occupancy (IO). Thus, the use of base isolators in high-level buildings is able to reduce post-earthquake damage and the building is still safe to continue using.

The multiplication operation is a crucial topic in learning mathematics. Nevertheless, there were still students who considered the topic to be a difficult topic, one of which was for elementary and junior high school students at the Graha Asuh Jabal 165 Foundation, Bandung Regency. These problems occur due to the learning process that is not optimal. Therefore, the purpose of carrying out this service activity is to help students or service targets understand the concept on the topic of multiplication operations which are packaged in an attractive way so that students are motivated to take part in the learning process. The method for implementing this activity consists of three stages, namely: (1) the activity planning stage; (2) implementation stage; and (3) evaluation stage. The results obtained in this service activity are in the form of student responses which indicate that students are very enthusiastic in participating in the learning process, and make it easy for students in the process of calculating multiplication operations.

The development of composite material engineering is an effective solution for the development of green building-based materials that are being campaigned in various parts of the country today. The fundamental problem in composite engineering that is developing is the lack of use of environmentally friendly materials as the basic material for composite constituents. The use of natural fiber-based composite materials as reinforcement is one of the right solutions to answer the issue of green building in producing more environmentally friendly materials with much better mechanical resistance. The study aims to determine the flexural characteristics of sandwich panel beams of sengon (SPS) in comparison to Meranti beams. The material used as skin for SPS beams is a composite of sisal fiber polyester from Sumbawa Island. Test standard based on ASTM C393 (length 550 mm, width 50 mm, thickness 25 mm), with a total of 5 specimens each. The test results showed that the SPS beams had an average bending stress of 167.66 MPa, while the Meranti wood beams produced an average bending stress of 94.29 MPa. The amount of bending stress produced by SPS beams is 43.38% higher than meranti wood beams. The average deflection value of SPS beams is 20.34 mm, greater than the average deflection value of sengon wood of 15.42 mm. This shows that the use of sisal polyester composite skin on SPS beams can produce better mechanical characteristics compared to Meranti wood.ABSTRAKPerkembangan rekayasa material komposit merupakan solusi yang efektif bagi pengembangan material berbasis green building yang sedang dikampanyekan di berbagai belahan negara saat ini. Permasalahan mendasar dalam rekayasa komposit yang tengah berkembang adalah minimnya penggunaan material ramah lingkungan sebagai bahan dasar penyusun komposit.
