Abstract

Damage to a tool can cause the production process to stop and cause downtime. Preventing damage to equipment is by managing the maintenance process. This process includes preventive maintenance, corrective maintenance and predictions of damage (predictive maintenance) which is carried out periodically. Centrifugal pumps have the working principle of converting kinetic energy (speed) of liquid into potential (dynamic) energy through an impeller that rotates in the casing. This pump is an impeller that is mounted on a shaft with bearings at both ends. Damage to the pump rotor has a serious impact on the performance and reliability of the pump system. The rotor is one of the main components responsible for transferring mechanical energy into the pumped fluid, so damage to the rotor can affect pump efficiency, operational life, and damage to pump components. Analysis of damage to the pump rotor was carried out by testing using the NDT method. NDT testing includes Visual Inspection, Magnetic Particle Inspection, Liquid Penetrant and Balancing Rotor. Based on the results of the tests and analysis carried out, it was found that there was damage to several parts of the pump rotor, such as corrosion on the pump shaft, dirt on the surface, and scratches on the mechanical seal seat area with a depth of approximately 0.50 mm. Rotor unbalance or the center of gravity of the shaft rotation is not the same as the geometric center of the shaft. The impeller was found to be in poor condition, high metal of radial impeller and medium to heavy rubbing at wearing impeller. The DE and NDE distance sleeves are not in a bad condition and there are scratches.

Abstract

Stunting merupakan salah satu permasalahan gizi kronis yang masih tinggi di Indonesia, khususnya di daerah pedesaan. Kondisi ini disebabkan oleh kurangnya asupan gizi dalam jangka waktu yang lama dan dapat berdampak pada pertumbuhan fisik serta perkembangan kognitif anak. Salah satu upaya pencegahan stunting adalah dengan Pemberian Makanan Tambahan (PMT) berbasis sumber protein lokal yang mudah diakses dan terjangkau. Penelitian ini bertujuan untuk menganalisis efektivitas program PMT melalui budidaya ikan lele dalam galon bekas sebagai solusi untuk meningkatkan status gizi anak stunting di Desa Bulan, Kecamatan Selopampang, Kabupaten Temanggung.Penelitian ini menggunakan metode kualitatif dengan teknik pengumpulan data melalui observasi, wawancara, dan dokumentasi. Program ini melibatkan mahasiswa Kuliah Pengabdian Masyarakat (KPM), pemerintah desa, kader posyandu, serta ibu-ibu PKK. Hasil penelitian menunjukkan bahwa budidaya ikan lele dalam galon bekas dapat menjadi solusi praktis dalam menyediakan sumber protein tinggi bagi anak-anak stunting. Selain itu, program ini juga meningkatkan kesadaran masyarakat tentang pentingnya pemenuhan gizi seimbang dan pemanfaatan limbah rumah tangga secara inovatif. Dengan adanya program ini, diharapkan angka stunting dapat ditekan, serta masyarakat dapat lebih mandiri dalam menciptakan lingkungan yang sehat dan menyediakan makanan bergizi bagi anak-anak mereka.

Abstract

This research aims to determine how the implementation of the Al-Qur'an reading activities in cultivating the interest of reading the Al-Qur'an among the members of Rohis at SMK Negeri 1 Wonosobo. To identify the problems in this study, the author uses a descriptive qualitative research methodology with field research type. The results of this study show that: 1) The implementation of the Al-Qur'an reading activities in extracurricular has been quite good, this activity is conducted once a month with the division of 1 juz per person. 2) In relation to the implementation of the Al-Qur'an reading activities in the Rohis extracurricular, fostering the reading interest of the Al-Qur'an among Rohis members at SMK Negeri 1 Wonosobo, this is evidenced by the fact that not a few Rohis members have been consistent in reading the Al-Qur'an. Initially, they only read 3 or 4 times a week, but after participating in the Al-Qur'an reading activities, they now read the Al-Qur'an every day. 3) For the internal hindrances, they lie in the varying abilities of Rohis members in reading the Al-Qur'an, which means that some children are still not fluent in their reading and have not yet mastered the rules of Tajweed. Meanwhile, the external hindering factors include several extracurricular activities that take place at the same time as the Rohis extracurricular activities, and other obstacles include the need for a special Rohis coach to teach Reading and Writing the Qur'an (BTQ). The supporting factors for this activity are adequate school facilities, a positive and motivating environment.

Abstract

This study aims to analyze the effect of Return on Equity (ROE) on stock prices with Price to Book Value (PBV) as an intervening variable in companies listed on the Indonesia Stock Exchange (IDX). This study uses a quantitative approach with multiple linear regression methods. The sample consists of 64 company financial report data selected through purposive sampling technique. The results showed that ROE has no significant effect on stock prices, with a significance value of 0.511. In contrast, PBV has a positive and significant effect on stock prices, with a significance value of 0.002. Simultaneously, ROE and PBV have a significant effect on stock prices, as indicated by the significance value of the F test of 0.006. However, the R Square value of 0.155 indicates that this model is only able to explain 15.5% of the variation in stock prices, while the rest is influenced by other factors outside the model.
