This freedom also includes the propagation of religious teachings as an ideology for transformation to real life. For Muslims, especially da'i certainly have great ideals for the realization of a prosperous fair society that is directed by Allah SWT. It can be fought, one of which can be through social organization.During the 72 years of independent Indonesia, several regulations issued by the government to regulate the system and mechanisms of mass organizations have added controversy to Islamic mass organizations. In the new order, some organizations threatened to be dissolved and not recognized for rejecting the sole principle of Pancasila. The dynamic continues until the reform era. This can be an afterthought for the da'wah perpetrators, especially those who take the path of the organization to pay more attention to the basic aspects of administrative formation with respect to the state / government, because it will subsequently be very influential on the sustainability of da'wah in the future.</em></p>

This research aims to create a Reosquido desalination tool for evaporation methods using a microcontroller. This tool can control the temperature to speed up the evaporation process in producing fresh water. The method applied to Reosquido desalination uses Evaporation. The first process before evaporation is the detection of temperature in sea water that will be heated using an element heater. The second process of temperature measurement is to turn off and turn on the Arduino Uno controlled heater, when the temperature is less than 80 ° then the heater is on. The third process is evaporation during temperatures between 80 ° to 100 °, evaporation water sticks to the glass roof which is designed by pyramid. Evaporated water that flows into the reservoir is detected by its solubility TDS value. The fourth process is heater off when the temperature is more than 100 °. Based on the results of the testing, the desalination process using a microcontroller controlled heater can speed up the time up to 55% of the previous desalination process tool, namely manual desalination process without using the heater element controlled by the temperature and controlled by a microcontroller which takes 9 hours. Produces fresh water as much as 30ml from 3000ml of sea water, so that it can be compared to 1: 100 ABSTRAK Penelitian ini bertujuan untuk membuat alat Reosquido desalination metode evaporasi dengan menggunakan mikrokontroller. Alat ini dapat mengontrol suhu untuk mempercepat proses evaporasi dalam menghasilkan air tawar. Metode yang diterapkan pada Reosquido desalination menggunakan Evaporation. Proses pertama sebelum evaporation yaitu pendeteksian suhu pada air laut yang akan dipanaskan dengan menggunakan element heater. Proses kedua pengukuran suhu untuk mematikan dan menghidupkan heater yang dikontrol Arduino Uno, ketika suhu kurang dari 80° maka heater on. Proses ketiga yaitu terjadinya evaporation selama suhu diantara 80° sampai 100°, air evaporasi menempel pada atap kaca yang didesain pyramid. Air hasil evaporasi yang mengalir ke penampungan dideteksi nilai TDS kelarutannya. Proses keempat heater off ketika suhu lebih dari 100°. Berdasarkan hasil pengujian, proses desalination menggunakan heater yang dikontrol mikrokontroller dapat mempercepat waktu hingga 55% dari alat proses desalinasi sebelumnya yaitu prsoes desalinasi secara manual tanpa menggunakan element heater yang dikontrol suhunya dan dikendalikan dengan mikrokontroller yang memakan waktu 9 jam. Menghasilkan air tawar sebanyak 30ml dari 3000ml air laut, sehingga dapat diperbandingan 1:100.

Due to the small down-flooding angle, the available intact stability criteria were difficult to apply to an Indonesian traditional wooden. This paper discusses the application of the dead ship criteria of Second Generation Intact Stability Criteria as an alternative method to assess the stability of the Indonesian traditional wooden boats. The hydrodynamics factors correspond to the formula to calculate the heel angle due to wave were determined by model experiments. The calculations were conducted for four different down-flooding angles consisting of 20 degrees, 25 degrees, 30 degrees and 35 degrees with scattered wave data of Lombok Strait. The results showed that the critical metacentric height decreases if the down-flooding angle increases. The minimum area under the righting arm curve up to the down-flooding angle tends to be independent of the down-flooding angle. The capsizing index corresponds to the critical metacentric height decreased when the down-flooding angle increased. These results showed that the method to assess ship stability in the Second Generation Intact Stability Criteria could be used to evaluate the stability of the Indonesian traditional wooden boats.

The development of technology brings a bunch of changes in every aspect in the world. In the education fields, it brings new concepts; a sense of easiness in learning and teaching process, such as, easiness of receiving information (knowledge) through internet, conducting teaching and learning process in distance area. This new concept is called shift -learning. E-learning systems are different from learning that is usually held in class (traditional learning). In industrial revolution 4.0, it is important that we use internet to fulfill the objective of education. This paper aims to identify the way fresh students from remote areas handle this situation. This research used descriptive qualitative. The research subjects consisted of 12 students of the English Language Study Program of Universitas Ahmad Dahlan in 2019. Data collection techniques were carried out using observation and interviews. From the student's perspectives, it was found that Shift-learning (e -Learning) is not something new for them, Shift-learning (e -Learning) leads students to broaden their knowledge, making them flexible to access the materials. However, less supported facility becomes the significant challenge. It showed that most English students from remote areas are ready to use e-learning in learning English because e-learning is not something new to them. Although less supporting facility and guidance from lecturers become the challenges for students, these do not stop them from using elearning. Keywords E-Learning, Learning shifting, Students perception, Students readiness ABSTRAK Perkembangan teknologi membawa banyak perubahan di setiap aspek di dunia.

Selain itu, fasilitas yang kurang mendukung dan minimnya bimbingan ...

This paper discusses the dead ship criteria applied to Indonesian ro-ro ferries. Model experiments consisting of roll decay and roll test in beam seas were conducted to calculate the hydrodynamics factors corresponding to the vulnerability criteria level 1 and level 2 of the dead ship criteria. The results show that the damping factors were smaller than those in the weather criterion. The effective wave slope coefficient was not significantly different from that obtained by the weather criterion when the radius gyration coefficient was the same as that calculated by the formula in the weather criterion. The ships comply with the weather criterion in full loading condition for the hydrodynamics factors determined by the weather criterion and by a model experiment. Inconsistency between the vulnerability criteria level 1 and the vulnerability criteria level 2 was obtained when the scatter wave data of IMO was used to calculate the capsizing index.
