Abstract

This research focuses on analyzing the stability of three types of retaining walls cantilever, gravity, and sheet pile to address landslide risks along the Enim River in Tanjung Karangan Village, Muara Enim Regency. The village is prone to landslides due to high riverbanks and unstable soil conditions exacerbated by erosion and settlement encroachment. To mitigate these risks, retaining walls are crucial in maintaining slope stability and preventing further erosion. The study utilized Windows Forms methods to perform numerical simulations and evaluate key factors such as the safety factor, sliding resistance, overturning resistance, bearing capacity, and material strength of the designed walls. The cantilever retaining wall design proved effective, achieving safety factors for overturning (1.80), sliding (1.51), and bearing capacity (1.31), making it suitable for implementation at the study location. However, the gravity retaining wall, despite meeting safety requirements for overturning (1.72) and bearing capacity (1.35), failed in sliding, with a safety factor of 1.49, indicating it is not appropriate for this case due to insufficient sliding resistance. The analysis of the sheet pile retaining wall focused on embedment depth and material quality. A steel sheet pile with a length of 9 meters, an embedment depth of 4.82 meters, and material properties of Fy = 450 MPa and E = 2.1 x 105 MPa was determined to be a feasible solution. The findings conclude that both cantilever and sheet pile retaining walls can effectively mitigate slope instability and riverbank erosion, while the gravity retaining wall is not suitable for the given conditions. These results provide valuable insights for future infrastructure development in landslide-prone areas.

Abstract

The poly methyl methacrylate (PMMA) research has been excecuted. Methyl methacrylate is polymerized by the free radical inisiation with the suspension condition using benzoyl peroxyde inisiator, water as a solution and the gelatine stabilizer, in this reseaarch is executed as a standard ratio (part per part:monomer : water : stabilizer = 100 : 350 : (0.1 1) with the inisiator to monomer ratio variation (part per part) are: 0.1 per 50; 0,175 per 50; 0,25 per 50; 0,25 per 50, the temperature variation are : 30 degree C, 45 degree C, 60 degree C and the time polymerization until 320 minutes. The result showed that the optimum monomer polymerizeation was at the inisiator to monomer ratio 0,25 per 50, the temperature at 45 degree C and at the time polymerization until 300 minutes with the monomer conversion was 86 percent. The Infra Red Spectroscopy analyses showed that there are poly methyl methacrylate in the product. The Gas Liquid Chromatography analysis showed the evolution of the monomer (methil methacrylate concetration.

Abstract

Pandemi covid 19 terjadi secara mendadak sehingga pembelajaran pada semua jenjang Pendidikan terjadi secara daring. Pembelajaran daring dilakukan tanpa ada persiapan guru dan siswa sehingga dilakukan dengan cara seadanya menggunakan media sosial dan learning management system. Penelitian deskriptif kuantitatif ini bertujuan untuk mengetahui perbedaan pembelajaran daring dan luring pada matapelajaran biologi di SMU. Subyek penelitian adalah siswa seluruh siswa SMUN 1 Bojonegoro dengan sampel kelas XI yang berjumlah 105 orang. Sampling dilakukan dengan cara purposive sampling. Data hasil penelitian adalah nilai ulangan harian biologi saat melakukan pembelajaran daring dan luring. Analisis data dengan menggunakan analisis varians dua jalur berbantuan SPSS. Hasil penelitian menunjukkan bahwa perbedaan hasil belajar yang signifikans antara system pembelajaran daring dan luring, tidak ada perbedaan pembelajaran daring dan luring pada kategori kelas (rendah, sedang, dan tinggi), ada interaksi signifikans antara kategori kelas dan system pembelajaran terhadap hasil belajar biologi di sekolah menengah. Temuan menarik dari penelitian ini ada kecenderungan kelas rendah mempunyai mean lebih tinggi dari kelas sedang maupun tinggi pada system pembelajaran daring meskipun dari hasil uji varian tidak menunjukkan perbedaan. Ini menjadi peluang untuk penelitian lanjutan.

Abstract

The forest area that plays a role in conservation efforts in Sumedang is the Gunung Palasari Grand Forest Park (TAHURA). These efforts can fail with various threats such as deforestation, exploitation and even economic pressure on the community that puts the condition of the area in a critical situation. The stages of prevention of this threat involve collaboration from various parties, such as academics, the community, and various other stakeholders. The purpose of this study is to invite the community and its surroundings to know the role of trees and want to play a role in planting trees for environmental conservation and developing the community's economy. The academics who contributed were the Faculty of Forestry, Winaya Mukti University, who took an approach through the seminar lecture method. The seminar was held on November 29, 2024 from 08.00 - 16.00 at TAHURA Gunung Palasari which was divided into three sessions, namely material presentation, discussion and tree planting. The material presented was targeted to gain community knowledge about plants, especially trees and their benefits, as well as public awareness to understand the importance of planting trees. This activity was declared successful in achieving its target based on the N-gain test, which obtained 60% from the difference in each pre-test to post-test parameter. The suggestion from this research is that routine planting activities should continue to be carried out.

Abstract

Nefrolitiasis atau batu ginjal merupakan salah satu gangguan saluran kemih yang prevalensinya terus meningkat di berbagai negara, termasuk Indonesia. Penggunaan tanaman obat sebagai terapi alternatif telah banyak dilakukan, salah satunya Strobilanthes crispus (keji beling) yang secara empiris memiliki efek peluruh batu ginjal. Efektivitas tanaman ini berkaitan dengan keberadaan senyawa aktif salah satunya adalah stigmasterol. Penetapan senyawa marker menjadi aspek penting dalam proses standardisasi untuk menjamin kualitas dan konsistensi produk herbal. Metode analisis berbasis kromatografi, seperti Kromatografi Cair Kinerja Tinggi (KCKT), banyak digunakan dalam identifikasi, uji stabilitas dan penetapan kadar senyawa marker. Hasil penelitian menunjukkan stabilitas senyawa aktif stigmasterol pada produk kapsul herbal dalam rentang waktu 0–24 jam, terdapat penurunan area pada larutan standar kurang dari 2% dan pergeseran waktu retensi (tR) juga kurang dari 2%. Hasil pengujian diperoleh persen kadar stigmasterol sebesar 16,07% dengan nilai Vxo 3,48%. Nephrolithiasis, or kidney stone disease, is one of the most common urinary tract disorders, with a prevalence that continues to increase worldwide, including in Indonesia. The use of medicinal plants as alternative therapies has been widely explored, one of which is Strobilanthes crispus, which is empirically known for its diuretic and lithotriptic effects. The effectiveness of this plant is associated with the presence of bioactive compounds, particularly stigmasterol. The determination of marker compounds is a crucial aspect of the standardization process to ensure the quality and consistency of herbal products. Chromatography-based analytical methods, such as High-Performance Liquid Chromatography (HPLC), are commonly employed for compound identification, stability testing, and quantification of marker compounds. The results of this study demonstrated that stigmasterol exhibited good stability in herbal capsule formulations within a time range of 0–24 hours, with a decrease in standard solution area of less than 2% and a retention time (tR) shift was below 2%. The stigmasterol content was determined to be 16.07%, with a Vxo value of 3.48%.
