Abstract

Acid mine drainage (AAT) is water formed at mining sites with a low pH (pH<6) as a result of opening up a potential for rock acidity, causing problems for water quality, rocks containing sulfide minerals. The purpose of this study was to determine the effect of using calcium hydroxide (Ca(OH)2) and aluminum sulphate ((Al2SO4)3) at optimum doses on neutralixing pH and reducing metal content in AAT. This study used a variation of the dose of calcium hydroxide (Ca(OH)2) of 0,5; 0,75; 1; and 1,25 grams and the variation of the dose of aluminum sulphate ((Al2SO4)3) of 1; 1,75; 2,5; and 3,25 grams with a contact time of 20 minutes. The initial concentration of TSS acid mine drainage was 430 mg/L, Fe was 26,92 mg/L, Mn was 7,69 mg/L, and pH was 3,8. The results showed that the doses of calcium hydroxide (Ca(OH)2) and aluminum sulphate ((Al2SO4)3) had an effect on Ph, TSS, Fe, and Mn. TSS removal efficiency was 96,89%, Fe was 99,74%, and Mn was 95,19%.

Abstract

The increasing number of new students studying at SD Ummu Aiman has resulted in a shortage of space in the school building. Therefore, the addition of a new building is required to address this issue. However, the region of Indonesia, especially Java Island, is prone to earthquakes, making it necessary for all infrastructure development to consider earthquake resistance. SD Ummu Aiman's building is no exception, thus requiring special design and supervision to reduce the risk of losses due to earthquake loads that could affect the structure. This case study report will discuss the planning and design of a three-story building made of reinforced concrete for SD Ummu Aiman. In the preparation of this report, the emphasis will be on load analysis, SAP 2000 modeling, and reinforcement control analysis to understand the results of the preliminary structural design and analyze the reinforcement of beam structures using the special moment frame method. The results of the structural design include a 10 cm and 12 cm thick slab with main reinforcement of Æ8-100, the size of the main beams is 35/25 with main reinforcement of 2Æ16 2Æ14 and shear reinforcement of Æ8-150, 25/20 with main reinforcement of 2Æ16 2Æ14 and shear reinforcement of Æ8-120, and the size of secondary beams is 25/20 with main reinforcement of 3Æ25 2Æ25 and shear reinforcement of Æ8-200. The column size is 30/30 with main reinforcement of 4 D16 2 D12 and shear reinforcement of Æ8-150, and 25/25 with main reinforcement of 4 D12 and shear reinforcement of Æ8-150.

Abstract

Abstrak : Operasi rata-rata dalam 1 bulan dengan tindakan spinal anestesi adalah 300 kasus dengan tindakan section caesarea sekitar 160 kasus yang terbagi menjadi tindakan elektif sekitar 110 dan cito sekitar 50 tindakan. di dapatkan bahwa pasien dengan tindakan sectio caesarea pasca operasi yang mengalami mual muntah lumayan banyak sekitar 36% .Sehubungan dengan hal tersebut maka dipandang perlu untuk meneliti“Pijat Refleksi untuk kejadian Mual Muntah (PONV) Post Sectio Caesarea dengan spinal anastesi di RSUD H.Sahudin kutacane.”Tujuan : Penelitian ini bertujuan untuk mengetahui Pengaruh Teknik Pijat Refleksi dalam Mengatasi Mual dan Muntah (PONV) pada Pasien Post Sectio Caesaria dengan spinal anastesi.Metode: penelitian ini adalah metode pre eksperiment dengan the static group comparism,dimana terdapat dua kelompok, kelompok intervensi dan kelompok kontrol. Penelitian ini dilaksanakan di RSUD H.Sahudin Kutacane, pada bulan Mei-juni 2023. Jumlah sampel adalah 60 responden yang terdiri dari 30 responden kelompok kontrol dan 30 responden kelompok intervensi. Hasil : Berdasarkan hasil penelitisn, diperoleh nilai signifikansi (p-value) yang mengindikasikan adanya pengaruh yang signifikan dari Teknik Pijat Refleksi dalam Mengatasi Mual dan Muntah (PONV) pada Pasien Post Sectio Caesaria dengan spinal anestesi di RSUD H.Sahudin Kutacane. Nilai p-value sebesar 0,00 menunjukkan bahwa perbedaan antara kelompok kontrol dan kelompok intervensi dalam hal yang sedang diuji tidak terjadi secara kebetulan.Kesimpulan : Terdapat perbedaan yang signifikan antara kelompok kontrol dan kelompok intervensi dalam hal usia, jenis kelamin, pendidikan, serta skor RINVR sebelum dan setelah tindakan. Hal ini menunjukkan bahwa Teknik Pijat Refleksi memiliki pengaruh yang berpotensi efektif dalam mengurangi gejala mual dan muntah pada pasien pasca operasi. Kata Kunci : Pijat,refleksi,kejadian mual muntah (ponv), seksio sesarea, anastesi spinal Abstract :The average operation in 1 month with spinal anesthesia is 300 cases with about 160 cases of caesarean section which is divided into about 110 elective actions and about 50 cito actions. It was found that patients with postoperative sectio caesarea who experienced nausea and vomiting were quite a lot, around 36%. In connection with this, it was deemed necessary to research "Reflexology for Nausea Vomiting (PONV) Post Sectio Caesarea with spinal anesthesia at H.Sahudin Hospital kutacane.”This study aims to determine the effect of reflexology techniques in overcoming nausea and vomiting (PONV) in post-sectio caesarean patients with spinal anesthesia.this research is a pre-experimental method with the static group comparism, where there are two groups, the intervention group and the control group. This research was conducted at H.Sahudin Hospital Kutacane, from May to June 2023. The number of samples was 60 respondents consisting of 30 respondents in the control group and 30 respondents in the intervention group.Based on the results of the study, a significance value (p-value) was obtained which indicated a significant effect of the Reflexology Technique in Overcoming Nausea and Vomiting (PONV) in Post Sectio Caesaria Patients with spinal anesthesia at H.Sahudin Hospital Kutacane. The p-value of 0.00 indicates that the difference between the control group and the intervention group in terms of what is being tested does not occur by chance.There were significant differences between the control group and the intervention group in terms of age, gender, education, and RINVR scores before and after the treatment. This shows that the Reflexology Technique has a potentially effective effect in reducing the symptoms of nausea and vomiting in postoperative patients.

Abstract

Today's technological developments encourage many companies to try to make it easier for the needs and convenience of online transactions, one of which is introducing a website-based booking service system and spare parts store. However, there are still challenges in designing optimal user interfaces and user experiences to achieve the company's business goals. This study aims to apply the User Centered Design (UCD) method to the appearance of an online booking service system and website-based spare parts shop at CV Saluyu Mandiri Pratama. User Centered Design (UCD) is an approach that focuses on the user in the entire manufacturing process, starting from user understanding, requirements gathering, prototyping, to user evaluation. The research methodology includes the stages of analyzing user needs and user context, creating interface concepts, developing prototypes, and evaluating users. Analysis of user needs is carried out through interviews, observation, and literature studies to understand user needs and preferences. Prototype development is carried out using interface creation tools that allow users to visually interact with the system. The results of this study are applications that pay attention to user needs and preferences, and provide optimal user experience. The User Centered Design (UCD) method has proven to be effective in assisting companies in designing systems that are more relevant and satisfying to users.
