Abstract

Sampah merupakan masalah yang masih belum bisa teratasi dengan baik. Mulai dari pengumpulan, pengolahan, penggolongan dan lainnya. Oleh karena itu, sebagai manusia selalu dituntut untuk sadar diri dan bertanggung jawab atas sampahnya. Salah satu perumahan yang masih banyak masyarakat atau warganya belum mengetahui tentang penggolongan dan pengelolaan sampah yaitu Perum Puri Harapan Blok E RW 6. Terlihat dari adanya saluran pembuangan air yang sangat kotor. Masih terdapat banyak sampah disana. Warganya membuang sembarang dan tidak memperhatikan sampah jenis apa yang dibuang. Padahal jika diperhatikan, sampah itu terdiri dari tiga jenis golongan (organik, anorganik dan Bahan Berbahaya dan Beracun) dengan cara pengelolaan yang berbeda. Jika dibuang sembarang dan tidak dikelola dengan baik maka akan terjadi penumpukan besar-besaran. Sehingga dapat menimbulkan banyak dampak negatif seperti polusi udara, polusi air, bibit penyakit dan banyak lagi. Penyuluhan ini dilakukan secara deskriptif yaitu membuat penyuluhan atau sosialisasi dengan cara penyampaian fakta-fakta secara sistematis mengenai penggolongan dan pengelolaan sampah. Tujuannya agar menyadarkan masyarakat akan pentingnya penggolongan sampah dan melakukan pembersihan areanya.

Abstract

CEGEONE (CG) is a manufacturing industry company in furniture. It is a supplier company for the Horrison & Gil company. The company manufactures furniture from raw materials into semi-finished goods. The company produces its products on consumer demand (customized order). The overwhelming and varying amount of demand each period was a major problem in the company's production. Hence it takes scheduling. Production scheduling is an important process in production system. In the production process, particularly in the Shop Machine line there is often bottle neck. Under that, researchers did production scheduling at the Shop Machine with the Campbell Dudeck Smith (CDS) method. This method uses Johnson's algorithm that aims to determine the order of the job in order for the earned makespan to be smaller than before. Using production scheduling on shop machines, the company can reduce the total process time to complete the job by 95 minutes or 1 hour 35 minutes. Smaller compared to the previous total makespan of 250 minutes or 4 hours 10 minutes. So that shows total savings in production at 19.79%. The results of the study can be concluded that by using production scheduling on shop machines.

Abstract

Production activities at manufacture companies are often inconvenient. One of them is due to the incompatibility of workers anthropometry with the work facilities used. Disergonomics like this will cause complaints in the skeletal system. Complaints to this damage are termed musculoskeletal disorder (MSDS). The production process of making shoes at UD. Kurnia at the subordinate work station identified that work posture has the potential to cause injury to the arm, back and leg muscles with a percentage of 66.67%, 68.89% and 30%. So it is necessary to improve work posture. In this study, the OWAS method was used to identify and evaluate hazardous work postures. Meanwhile, to improve work posture, work facilities are designed using anthropometric data for subordinate work station workers. Owas identification results show that the work posture is more ergonomic. Then the results of the WinOwas software show that the improvement of work posture with the design of work facilities is included in category 1. Which means that the work posture is not dangerous. So it is directly believed that workers complaints on skeletal muscles or MSDs at subordinate work stations can be minimized.

Abstract

Determining the petrophysical rock type often excludes measured multiphase flow properties, such as relative permeability curves. This is due to limitations in SCAL experiments or difficulties in correlating relative permeability characteristics with standard rock types. However, with a significant number of relative permeability curves, Machine Learning methods can be applied to automatically and objectively classify rock types based on the shape of these curves. This approach combines principal component analysis with unsupervised clustering schemes and preprocesses relative permeability curve data by integrating irreducible water saturation and residual oil. The methodology was tested on real data from carbonate reservoirs with a substantial number of relative permeability curves, demonstrating successful clustering based on fractional flow curves. The results indicate that this clustering can classify rocks from poor to optimal displacement efficiency. Furthermore, the study highlights the importance of high-quality SCAL experiments for normalizing curves and ensuring consistency between capillary pressure measurements and relative permeability. This Machine Learning approach is also compared with capillary pressure analysis, showing that relative permeability data provides additional information in rock typing studies, affirming the feasibility of Machine Learning for automatic rock type classification.

Abstract

Penambangan batugamping di Indonesia umumnya dilakukan pada morfologi conical hill, akibatnya penambangan dapat mengalami longsor sehingga perlu dilakukannya analisis kestabilan lereng. Tujuan penelitian adalah memberikan rekomendasi kelerengan pada penambangan batugamping menggunakan Limit Equilibrium Method (LEM) dan kinematika lereng quarry “J”. Terdapat struktur geologi right slip fault pada daerah dominan satuan batugamping. Hasil analisis LEM dilakukan dengan skenario pada kemiringan lereng aktual (41°), landai (30°), dan terjal (60°). Nilai faktor keamanan lereng aktual sebesar 393.656 menggunakan metode Fellenius yang termasuk dalam kategori lereng stabil, hal ini wajar dikarenakan nilai properti material (UCS, kohesi, dan phi) batugamping yang tinggi. Hasil analisis kinematika menunjukkan dapat terjadinya dua potensi longsor yaitu wedge dan toppling akibat keberadaan struktur geologi pada lereng. Tipe wedge menunjukkan nilai critical percentage kelongsoran sebesar 1,3%  pada slope aktual, apabila slope diterjalkan, nilai critical percentage kelongsoran meningkat pada slope 54°-58° sebesar 3,4-6%. Sedangkan tipe toppling menunjukkan nilai critical percentage kelongsoran sebesar 0% pada slope aktual, apabila slope diterjalkan, nilai critical percentage kelongsoran meningkat pada slope 58°-60° sebesar 2,2-3%. Berdasarkan hasil kedua metode, direkomendasikan slope lereng penambangan diterjalkan sampai 60o sehingga produksi penambangan batugamping meningkat sesuai dengan faktor keamanan dan kestabilitas lerengnya
