The diversity of fish species at most in this season are Euthynnus affinis, Elagatis bipinnulata, Katsuwonus pelamis, Scomberomorus sp. and Selar crumenophthalmus. Diversity at most on the rainy season is Pampus argenteus, while in the dry season are Stolephorus sp., Elagatis bipinnulata, and Auxis rochei. The method of selling fish was done through fishermen, brought to the fish auction to bought by collectors, traders, and consumers. The selling price of fish on traders and collectors has doubled from the fishermen. The abundance of crops has an impact on welfare of fishermen, consumers and traders. The harvest season also has positive impact on social, tourism and culture. The conclusion from this study is the seasonality affects to diversity of fish species, selling price is relatively stable, and has positive impact on society in terms of economic, social, cultural and tourism
Tensile Strength of Bamboo After Preservation
No full textBamboo has high tensile strength, so it can be an alternative to substitute wood or steel. Bamboo is a material that comes from nature, so it is vulnerable to degraded by weather changes and infected by termites and fungi. The effort to overcome this problem is by preserving before using it. This study aims to determine the tensile strength test results of bamboo after preserving and then compare with the tensile strength test results of bamboo without preserving. The research method was carried out by preserving bamboo by soaking the test sample in a container filled with water for a duration of time; 1 x 24 hours; 3 x 24 hours and 14 x 24 hours. The water used in freshwater with a salinity of 0 0/00 measured using a salinometer. The results showed that the tensile strength of bamboo increased compared without preserved with a percentage of 12.50%; 23.12% and 10.59% for the duration of time respectively 1x24 hours; 3x24 hours and 14x24 hours. Optimal tensile strength is obtained at a time duration of 3 x 24 hours and decreases at a longer time duration of 14x24 hours
Redesign Facility Layout and Minimize Material Handling Cost on PT ABC in Pandemic Era
No full textSince March 2020 the news of Covid-19 has spread in Indonesia, with this situation there have been many changes in the industrial sector in Indonesia. In this situation, industry players should make adjustments to their production processes so they can continue and run safely. According to information from the Ministry of Health and the Task Force for the Acceleration of Handling Covid-19, one of the health protocols to prevent the spread of Covid-19 is physical distancing, where the minimum distance between workers is 1 meter. So to deal with this condition, of course, it is necessary to redesign the layout of the factory facilities. Layout is an important decision that determines the efficiency of long-term operations. PT ABC is a company engaged in the processing of metal goods. In addition to implementing health protocols, PT ABC also has problems in structuring work facilities that are not quite right. This can lead to less effective and efficient workers for moving the material, thus causing a lot of work in process. The analysis method to these problems uses the ARC (Activity Relationship Chart), ARD (Activity Relationship Diagram), and Flexsim 6.0 simulation method to determine the Material Handling Cost and production output. Layout changes that have been made, can minimize material handling costs which were previously 22,717.76 to get $ 6129.4 or about 21%
Quantum State Tomography of Single Qubit Using Density Matrix
No full textThe quantum state tomography is a fundamental part in the development of quantum technologies. It can be used to know the signal characterization of small particle called photon in the nanoscale. In this study, photon number has been measured in order to produce the states tomography. Optical devices and quantum-mechanical approaches were explored to obtain the quantum state tomography. Due to a single qubit state density matrix can be revealed by Stokes parameters, so there are four set-ups to measure the Stokes parameters for each sample. The density matrix is used because the pure state only appear theoreticaly. In the real experiment, It always exibits a mixed state. The samples of tomography measurements consist of linear state, cicular state and the IR 808nm. In this study, state tomography is shown by 2x2 density matrix. This experiment also provides the fidelities of experiment result. And it shows the good agreement. From this experiment, the state of IR 808nm has been detected. The laser that examined is showing a vertical state with fidelity F=97,34%

INTEGRASI SHALAT DALAM PERSPEKTIF MATEMATIKA ISLAM
No full textMatematika Islam adalah matematik yang bersumber dari Al-Qur’an dan sunnah Rasullullah SAW. Dalam agama islam ada lima kewajiban yang dianjurkan kepada umatnya yaitu rukun islam yang menjadi pondasi atau tindakan dasar bagi setiap umatnya. Lima tindakan dasar yaitu syahadat, shalat, zakat, puasa dan haji (bila mampu). Shalat merupakan satu-satunya kewajiban umat muslim yang tidak bisa ditawar. Tidak seperti kewajiban yang lainnya seperti puasa, seseorang diperbolehkan tidak berpuasa apabila orang tersebut tidak mampu dalam keadaan apapun. Sebenarnya ada banyak hal yang belum kita ketahui tenang solat dalam pandangan matematika islam. Penulisan ini bertujuan untuk mengetahui korelasi dari sudut pandang shalat dalam matematika islam. Bagaimana jika shalat dikatkan dengan dengan sudut pandang matematik islam. Oleh karena itu, pentingnya mempelajari matematika islam dalam dunia pendidikan dengan nilai-nilai yang terkandung dan bersumber dari agama islam dan Al-Qur’an. Sehingga selain mempelajari ilmu matematika, pelajar juga secara langsung mempelajari keagungan Allah dan firmannya yang diajarkan kepada manusia secara logika dan apa-apa yang manusia belum mereka ketahui.
