Abstract

The Cimahi City has experienced a decrease in the quality of raw water caused by flooding in several places, especially during the rainy season, therefore it is necessary to anticipate this by constructing infiltration wells, ponds, or lakes. Cimahi City has 5 lakes, one of which is the Ciseupan Lake. This lake can be one of the options for raw water sources in Cimahi City. Based on this, it is necessary to identify the water quality and trophic status of the lake so that it can be utilized optimally by local residents. This research aims to describe the status of water quality and trophic status of the Ciseupan Lake by analyzing the parameters of pollutant sources. The method for determining the status of water quality is the Pollution Index based on Decree of the Ministry of Environment Number 115 of 2002 concerning “Pedoman Penentuan Status Mutu Air”. Quality status can be determined according to the pollutant index classification, the greater the value, then the worse the water quality. The method for determining trophic status uses the UNEP-ILEC method. Based on the results of calculating the water quality status, the pollutant index value at the Ciseupan Embung in 2021 is 9.5 while in 2022 it is 8.9 which according to Minister of Environment Decree Number 115 of 2003, in both years the water quality status of the lake was included in the moderately polluted category. The trophic status of the Ciseupan Lake is classified as hypertrophic, this indicates that the lake water has been heavily polluted by nutrients.

Abstract

Banjir merupakan permasalahan drainase yang disebabkan oleh alih fungsi lahan untuk menunjang aktivitas masyarakat. Kecamatan Cianjur memiliki 11 Desa. Berdasarkan hasil observasi 4 dari 11 Desa di Kecamatan Cianjur sering terjadi banjir.  Banjir tersebut terjadi di Desa Bojong herang Jalan Dr. Muwardi (depan Islamic Center Kabupaten Cianjur), Desa Nagrak Jalan Raya Sukabumi (Depan Taman Makam Pahlawan), Desa Sayang di Jalan Aria Cikondang (depan Lembaga Permasyarakatan Kabupaten Cianjur), Desa Sawah Gede di Jalan Syariah Kavling B’elka. Permasalahan yang terjadi disebabkan oleh tertutupnya saluran inlet oleh pasir jalan raya yang menyebabkan air limpasan hujan tidak masuk ke dalam saluran drainase, saluran drainase tidak sesuai dengan debit limpasan sehingga air dalam saluran drainase meluap dan menyebabkan terjadinya genangan dan banjir. Berdasarkan hasil perhitungan penilaian skala prioritas yang terdapat pada Peraturan Menteri Pekerjaan Umum dan Perumahan Rakyat No.12 Tahun 2014 tentang Penyelenggaraan Sistem Drainase Perkotaan, penanganan banjir prioritas pertama harus dilakukan di Desa Bojong Herang, kedua di Desa Nagrak, ketiga di Desa Sayang, dan Ke empat di Desa Sawah Gede

Abstract

In competition in the industrial world, making quality products is mandatory for companies. The quality of the goods produced must be able to meet consumer desires. The company must also ensure that the production process runs well to produce quality products with an efficient process. This company is a subsidiary of Olympic Grub which is engaged in the manufacture of household furniture with the olymplast brand. the quality control implemented by the company is still not optimal, this is evidenced by the existence of product defects during the production process. Therefore, an analysis was carried out using the Failure Mode and Effect Analysis (FMEA) method with the aim of knowing the priority of disability problems for further repairs and the Fault Tree Analysis (FTA) method to get to the root causes that influence the occurrence of defects. From the results of the study it was found that there were types of defects including short, shinkmark, flowmark, and bending with a total of 415 defects. Based on the results of the calculation of the RPN value, the highest value was found for the type of shinemark defect so that it became a top priority in carrying out repairs. Based on this analysis, a search for the root of the problem was carried out using the FTA method, where it was found that there were 3 basic events including operators who did not understand SOPs, machine technology that had not been optimized and various raw materials for making tables where each was classified into 2 root causes for Next, a draft improvement proposal is carried out. Among them are providing machine setting training activities to all production employees, making written SOP, conducting trial errors, checking materials and completeness of tools before the production process.
