With the increasing era of globalization today, competition in the industrial sector is becoming increasingly fierce and competitive. With the development of modern technology for the better but on the other hand raises problems for the environment. Every business actor who wants to win the competition must pay full attention to the quality of the products or services produced, at a low cost, the right time and quantity, and safe conditions. This study aims to analyze and reduce waste of packaging waste at PT XYZ, a manufacturing company engaged in the manufacture of medicines and vaccines. In the last 7 months, there were 1,906 pcs of defective packaging out of a total of 204,940 pcs used. The defects were caused by mold, misprinted information, faded colors, and lack of glue on the packaging. The methods used in this research are Pareto diagram and fishbone diagram. Pareto diagrams are used to identify dominant product defects, while fishbone diagrams are used to identify the causes of defects. It is expected that the results of this research can help PT XYZ reduce packaging waste and improve the quality of their products. By reducing packaging waste, PT XYZ can also contribute to reducing negative impacts on the environment.

Geographically, Kadirejo village is located to the south of the Karanganom sub-district capital, which is still an integral part of the Klaten Regency area with a distance of 2 km from the sub-district capital and 7 km from the district capital, while from the provincial capital it is around 100 km. The Kadirejo village government has several parts of land that will have no access due to the closure of the Solo – Jogja toll road. To get around this, the Kadirejo Village Head wants to create a new tourist spot in the form of a Tiban market and fishing pond so that the village remains busy and increases the village's cash fund income through Bumdes. For this reason, the village head collaborated with academics to participate in planning the idea. The purpose of this community service is to help the community provide a brief description of partner problems and the goals of community service. The methods used are field surveys, data processing and reports. The final result is suggestions or recommendations regarding parking patterns and types of access roads to the tourist location in question. The recommended parking pattern is an island parking pattern with a type A fishbone shape (60° angle), and the road type is paving.

Quality control is crucial for the company to minimize the existence of defective products. The research focuses on the quality control section. The purpose of this study is to find out how the implementation of quality control occurs at PT Andalan Mandiri Busana, identify the factors that cause defects in garment products, and determine proposed improvements as an effort to suppress defective products. The results showed that there were factors that caused production defects and the biggest cause was broken stitches, and the sigma value obtained was 4.15, which means that the company has carried out pretty good quality control. Based on this research, the recommendations that can be given are in the improve stage, in the form of a table of proposed improvements using the Five M-checklist approach and Kaizen based on fishbone diagrams. The results of this study are expected to be one of the inputs for companies in implementing quality control and can increase the company's sigma level.

The internet is a computer network system that is connected to each other. To achieve an internet, you need a fiber optic network that can transfer certain information data up to speeds of up to 100Mbps. However, customer service often receives customer complaints regarding unstable Indihome network services in the Banyumanik STO area. So it is necessary to do research on Fiber Optic Network Analysis from Server to Optical Network Terminal (ONT) at PT Telkom Access Banyumanik STO Using the Fishbone Method. To analyze the causes that affect the quality of fiber optic network for good or bad. Network quality analysis was carried out using the Fishbone Diagram method as a basis for obtaining the results of measuring the quality of fiber optic networks at ODC BMK FAE/ODP BMK FAE 016 Jalan Banjarsari Barat – Jalan Tembalang Selatan. The results of network quality analysis through brainstorming sessions with 11 employees of PT Telkom Access obtained an average answer of 92%. Then measure the quality of the network in the field, namely from the Optical Line Terminal (OLT) to the Customer. The results obtained are directly proportional to the standard network quality analysis with an attenuation value of -19.10 dBm. So it can be concluded that the case study area has good network quality because the results of the average value of the questionnaire answers and the measurement results of the case study area have a value above the standard.

PT KMPI is an industrial company that produces textiles and plastics, including plastic products made of polypropylene (PP). The problem that occurs in PT Kusuma Mulia Plasindo Infitex is the quality of the products that still have defects, based on the results of the analysis in February 2023 with a total production of 76,596 kg there are rejects data of 4,695 kg and the percentage of product defects that occur is 6.1%. The objective of this study is to determine the predominant types of defects that influence the factors that cause defects. This study uses the seven tools method to find the root cause of the problem to be solved, as well as the Kaizen Five-M checklist and the Kaizen Five Step Plan to suggest improvements to the company. Based on the results of data processing, there are three types of defects, namely wrinkle defects with a percentage of 43% for a total defect of 2039 kg, medium wrinkle defects with a percentage of 45% for a total defect of 2094 kg, and thick-thin defects with a percentage of 12% for a total defect of 562 kg. From the fishbone diagram, it can be seen that the occurrence of defects is caused by several factors, namely people, materials, methods and machines. Suggested improvements using the Kaizen Five-M checklist analysis are training and monitoring of production, implementation of SOPs (Standard Operating Procedures) established by the company, such as dosing the mixture of plastic seeds with addictive substances at a ratio of 25 Kg. 1 oz. and Kaizen management control: 1 Ons and Kaizen five-step plan management controls, namely Seiri, Seiton, Seiso, Seiketsu, Shitsuke. This includes pre-job briefings and periodic assessments, and the establishment of standard operating procedures for the supervision of single-table melting machines with a melting temperature of 160-166oC.

Sebuah ketel uap  harus cukup  kuat  supaya  dapat  bekerja  dengan  aman pada tekanan tertentu, sehingga perlu dilengkapi pesawat-pesawat keamanan. Masinis di atas kapal mempunyai tuntutan agar secara rutin melakukan perawatan pada ketel uap bantu dengan berpegangan pada manual book yang sudah dibuat maker. Berdasarkan pengalaman saat berlayar di salah satu kapal ditemukan suatu kejadian bahwa auxiliary boiler beroperasi serta mengeluarkan uap bertekanan yang berguna untuk kecukupan kebutuhan uap di atas kapal. Bunyi pada alarm yang setelah diperiksa pada panel auxiliary boiler, ternyata alarm muncul pada flame failure dan lowest water level, sedangkan feed pump beroperasi normal serta masih dalam keadaan mengisi air ke dalam auxiliary boiler. Penelitian ini dilakukan untuk mengetahui faktor yang dapat mengakibatkan air masuk ke dalam furnace, mengetahui dampak yang dapat terjadi jika air  masuk ke dalam furnace serta mengetahui langkah yang dapat diambil untuk mengatasi masuknya air ke dalam Furnace. Metode penelitian ini menggunakan metode kualitatif. Sumber data diperoleh dari data primer maupun data sekunder. Teknik pengumpulan data yang  digunakan  adalah  wawancara,  observasi,  maupun  dokumentasi.  Teknik  analisis  data  yang digunakan adalah fishbone diagram dan USG. Hasil penelitian menunjukkan bahwa masuknya air ke dalam auxiliary boiler  disebabkan oleh retaknya dinding  furnace. Dampak  yang  ditimbulkan  yaitu terganggunya proses pembakaran di dalam furnace serta kerusakan pada komponen-komponen burner. Upaya yang dapat dilakukan adalah dengan mengelas bagian dinding furnace yang retak agar air tidak masuk ke dalam furnace.
