Abstrak-Ketepatan waktu, biaya, dan kualitas adalah hal yang menjadi perhatian dalam perencanaan proyek yang tertuang dalam penjadwalan proyek. Dalam pengerjaan proyek muncul beberapa masalah dalam perencanaan dan pengendalian proyek, yaitu sulitnya dipetakan jalur kritis dari suatu kegiatan. Pada PT. Bandar Abadi keterlambatan proyek sering terjadi akibat tertundanya penyelesaian kegiatan-kegiatan kritis dan berimbas pada biaya proyek semakin besar. Pada penelitian ini digunakan metode Critical Path Method (CPM) dan Project Evaluation Review Technic (PERT) yang digunakan membantu project manager dalam merencanakan dan mengendalikan proyek, di mana metode ini dapat membantu project manager dalam menentukan kegiatan kritis dan mengetahui estimasi waktu penyelesaian pada sebuah proyek. Hasil akhir yang didapatkan dalam penelitian ini adalah didapatkannya jalur kritis untuk pembangunan kapal dilengkapi dengan sistem informasi berbasis web yang dapat digunakan project manager untuk mengelola proyek pembangunan kapal dengan menggunakan metode PERT dan CPM, dapat membantu dalam mengelola proyek pembangunan kapal di PT. Bandar Abadi, menurunkan risiko keterlambatan proyek, dan mencegah munculnya biaya proyek akibat keterlambatan.

One consequence of a visually impaired (blind) person is a lack of ability in the activities related to the orientation and mobility. Blind person uses a stick as a tool to know the objects that surround him/her.The objective of this research is to develop a tool for blind person which is able to recognize what object in front of him/her when he/she is walking. An attached camera will obtain an image of an object which is then processed using template matching method to identify and trace the image of the object. After getting the image of the object, furthermore calculate and compare it with the data training. The output is produced in the form of sound that in accordance with the object. The result of this research is that the best slope and distance for the template matching method to properly detect silent objects is 90 degrees and 2 meters.

Data from the Central Bureau of Statistics shows that during the first quarter of 2014 to 2019, the tendency of Indonesian crayfish export increases by an average of 3.54% in 2019 and reach 7.09 million USD. This number still fails to meet the global market demand caused by poor water quality due to cultivators’ lack of experience and education. Two parameters measured in water quality are temperature and pH. Thus, a device was made using IoT to maintain those conditions in order to increase the viability of the crayfish in the pond. The perceptron method is used to classify water quality based on those parameters. To send the data, ESP8266 is used as an intermediary for Arduino and cloud server. The result is that the information about the ponds’ condition can be seen via a smartphone. The method gives a value of 98.06% accurate in determining water quality.

Blindness is a general term used for the condition of someone who experiences a disturbance or obstacle in their sense of sight. In general, blind people walk with special canes to help them walk and increase their safety. However, there are problems that arise when blind people walk home or go from a path that they are used to or to a place where they have never traveled. There is the possibility that blind people get lost and find it difficult to determine their way home because they don't know where they are going. For this reason, it is necessary to create a system that can monitor their whereabouts in real time and provide directions, provide information on the steps to their destination and they can also notify their families and related foundations if they are in trouble. For this reason, it is necessary to make an integrated tool with the haar cascade method to detect faces to find out whether there are humans or other obstacles that can shows 94% accuracy, in addition a global positioning system (GPS) can help blind people to show the direction of the destination.

Quality control can suppress or reduce the volume of errors and repairs in the future where it can also minimize costs incurred by the company if later there is damage. These activities must be carried out carefully and effectively so that the results obtained are in accordance with the initial objectives. In fact, the implementation of equipment quality control activities in the field at PT. Indonesia Comnets Plus SBU Regional Sumbagsel is still done manually so it is not practical and takes a lot of time. This research is a design science research (DSR) by making a decision support system to help determine the quality of equipment in the field and determine the level of urgency for repairs to the tower that suffered the most damage using the Multi-Objective Optimization On The Basis Of Ratio Analysis (MOORA) Method. The accuracy results obtained in the implementation of this method are 100%
