Abstract

Dinding penahan tanah adalah sebuah struktur yang didesain dan dibangun untuk menahan tekanan lateral tanah ketika terdapat perubahan dalam elevasi tanah yang melampaui sudut geser dalam tanah. selain itu juga dimaksudkan sebagai usaha memperlancar fungsi bangunan disekitarnya agar tidak ada hambatan. Dilakukan analisa perbandingan dinding penahan tanah tipe Bronjong dan geotekstil dengan tipe kantilever, bertujuan untuk evaluasi bila ada kerusakan dengan dinding penahan tanah saat ini. Berdasarkan latar belakang tersebut maka dibuat rumusan masalah sebagai berikut : 1.Bagaimana perbandingan dinding penahan tanah type bronjong dan geotekstil dengan type kantilever dengan menggunakan metode coulomb dan rankine? 2.Dinding penahan tanah manakah yang lebih ekonomis. Untuk membatasi ruang lingkup yang terlalu luas, maka penulis membatasi masalah pada : 1.Menghitung kontrol stabilitas terhadap guling (Overturning), dan geser (Shear/Slidding). 2.Menghitung kontrol stabilitas keruntuhan terhadap daya dukung tanah. -Tidak membandingkan kekuantan dinding penahan tanah. Data yang di peroleh dari PT. CIPTA ARTHA BORNEO dari data hasil lap di dapat bobot isi tanah () =18,22, tanah kohesi (c) =1.63, sudut geser (φ) = 26,84° dapat dihitung dengan menggunakan metode coulomb dan rankine. Berdasarkan hasil analisa dengan menggunakan metode rankine dan coulomb pada dinding penahan tanah tipe katilever di dapat stabilitas guling menurut rankine 3,212 > 2, stabilitas guling menurut coulomb 3,612 > 2. Stabilitas geser menurut rankine 2,019 > 2, stabilitas geser menurut coulomb 2,436 > 2 aman. Stabilitas keruntuhan menurut rankine 6,043 > 3, stabilitas kerntuhan menurut coulomb 6,345 > 3. Dan dinding penahan tanah tipe bronjong di dapat stabilitas guling menurut rankine 2,977 > 2, stabilitas guling menurut coulomb 3,164 > 2. Stabilitas geser menurut rankine 2,701 > 2, stabilitas geser menurut coulomb 2,871 > 2 aman. Stabilitas keruntuhan menurut rankine 10,540 > 3, stabilitas terhadap keruntuhan kapasitas daya dukung tanah di dapat menurut coulomb 10,855 >3.

Abstract

Road damage that occurs in various areas, especially in the Sanga Sanga - Dondang area, Kutai Kartanegara Regency is a very complex problem and the losses suffered are quite large, especially for road users, such as long travel times and traffic accidents. The cause of road damage that occurs in the Sanga Sanga - Dondang road section is the burden of excessive traffic (overloaded) and the slow handling of existing damage so that it becomes more severe. The method used in this survey is a method of visual analysis based on the Pavement Condition Index (PCI) method. The Pavement Condition Index (PCI) method is used to identify damage to the road surface based on the survey results, so that appropriate and efficient handling of repairs can be identified in the study. the Sanga Sanga - Dondang road section and the Geographic Information System (GIS) application function to facilitate the presentation of damage information in the form of maps. The most dense damage to the Sanga Sanga - Dondang Sta 0 + 000 - 18 + 000 road segment, especially in segments 1 to 11, Potholes, Alligator cracking, Weathering, Edge cracking and Patching. The average pavement condition index (PCI) value of the Sanga Sanga - Dondang road section is 33% based on the existing classification, the road segment is classified as poor (Poor) and refers to the PCI matrix for Class I Arterial Roads, the road needs to be done. reconstructed.

Abstract

IKM S is one of the small and medium enterprises (SMEs) in the food sector, particularly focusing on the production of soy sauce, chili sauce, and vinegar. One of the challenges faced in its supply chain is the shortage of bottle raw materials from suppliers, resulting in reduced production and a high number of returned products due to expiration. This research aims to identify the risks in the supply chain and determine strategies to address these issues. The research methodology used is quantitative descriptive, employing the Supply Chain Operation Reference (SCOR) method to identify risk events and House Of Risk (HOR) for mitigation strategies. The study's findings indicate 21 risk events and 19 risk agents. In HOR 1, severity levels of risk events, occurrence frequencies of risk agents, and the relationship between risk events and agents were measured, resulting in an Aggregate Risk Potential value. Four risk agents causing issues in operational activities were identified. HOR 2 identified four preventive actions and prioritized mitigation based on the effectiveness versus implementation difficulty ratios of these actions for the company.

Abstract

Tuberculosis (TB) remains a pressing health concern in Indonesia, with caregivers playing a decisive role in supporting treatment adherence and preventing household transmission. This community engagement project, conducted in Desa Keliling Benteng Ulu, South Kalimantan, sought to empower caregivers through structured educational and skill training using the Dingsanak Peduli TB module. Fifteen caregivers of TB patients participated in interactive sessions that combined knowledge transfer, demonstration, and skills practice. Knowledge assessment was performed before and after the intervention using domain-specific questionnaires covering TB transmission, household prevention, treatment adherence, family roles, and recovery support. Results showed a significant increase in mean knowledge scores from 56,7 to 85,3. The most pronounced improvements were observed in household prevention practices and treatment adherence, with caregivers reporting greater self-confidence in their caregiving roles. These findings highlight that structured caregiver empowerment can enhance household capacity in TB care and represent a scalable, community-based strategy to strengthen Indonesia’s TB control efforts.
