Abstract

Fitoplankton merupakan produsen primer di suatu perairan yang dapat menunjang kehidupansumberdaya hayati perairan lainnya dan menempati trofik level pertama dalamrantai makanan. Penelitian ini bertujuan untuk mengetahui struktur komunitas fitoplanktonserta hubungan antara konsentrasi fosfat dan nitrat dengan kelimpahan fitoplankton.Penelitian ini dilaksanakan pada bulan januari 2017 di perairan TanjungBalai Kota Kabupaten Karimun Provinsi Kepulauan Riau. Hasil dari penelitian ini ditemukan27 genus dari fitoplankton yang berasal dari 3 kelas, 7 ordo dan 16 famili.Adapun nilai kelimpahan fitoplankton berkisar antara 48 - 79 ind/l. Nilai indeks keanekaragaman(H’) berkisar antara 2,60 – 2,83, indeks dominasi (C) berkisar antara 0,20 –0,23 dan indeks keseragaman (E) berkisar antara 0,77 – 0,80. Berdasarkan uji regresilinear sederhana, model matematis konsentrasi fosfat dengan kelimpahan fitoplanktonyaitu y = 10.90 + (656.4)x dengan nilai korelasi (r) = 0,42 (tergolong sedang). Modelmatematis konsentrasi nitrat dengan kelimpahan fitoplankton yaitu y = 138.3 + (-1207)x dengan nilai korelasi (r) = 0,21 (tergolong lemah)

Abstract

A study on domestication and triggering gonadal maturation technique ofOsteochilus hasselti CV were conducted from March to May 2015. The study aimed to obtaina high quality brooder with good gonado somatic index and high quality eggs and sperm, inthat the fishes were treated with defference diets. Fish samples were kept in 1 x 1 x 1 mcages, with density of 20, 30 and 40 fishes/cage respectively. Fishes were fed on three typesof food namely dried Tubifex, shrimp pellet (without vitamin E addition) and shrimp pelletthat is enriched with vitamin E. The fishes was fed 10 % of total fish body weight/day. Itrevealed domestication can be conducted by keeping them in the cages that natural habitat.During the first week, fishes were not fed and in the following weeks they were provided withthe treated fed. The best result obtained in the fishes that are 20 fishes/cage and are feed withshrimp pellet that is enriched with vitamin E. During the research period (80 days), 20 fisheswere sampled in the 4th gonadal maturity level, their maturity indices was 14,7 %, fecundity360 eggs, egg diameter 0,936 mm and semen volume produced 0,575 ml.

Abstract

This research aims to evaluate the Chocolate Drink Processing Process of Halal Product Guarantees (Case Study: CV. Sultan Agro Maritim Industri in Kendari City). The research was designed using a case study method with a qualitative approach. Data collection was carried out using interviews, observation, and recording tape studies. The research results show that there are 3 research focus points, including (a) halal ingredients, (b) production facilities, and (c) products found in the chocolate drink processing process. Types of raw materials used (cocoa powder), cocoa beans, production facilities (supply of ingredients, processing, storage, packaging, sales), and products (chocolate drinks). Several factors influence the guarantee of halal products in the process of making chocolate drinks, including ingredients, products, and production facilities. The materials used are halal in terms of their substances, how to obtain the materials, and how they are processed. There are no products produced with brands or names that lead to haram, and sensory characteristics such as smell and taste are avoided in haram products. The same thing also applies to the production facilities used in making chocolate drinks, which are protected from haram ingredients, maintain cleanliness and purity, and ensure that there is no contamination from haram materials or products.

Abstract

Kipas angin merupakan perangkat elektronik konvensional yang gunakan sebagai pengatur sirkulasi udara saat cuaca panas. Pengoperasian kipas angin manual yang pengendalian ON/OFF dan kecepatan putaran (fan speed) pada kipas angin kebanyakan dikendalikan secara manual dengan saklar atau remote control terasa kurang efisien. Oleh karena itu diperlukan suatu sistem untuk mengendalikan ON/OFF dan kecepatan putaran kipas angin secara otomatis dengan menyesuaikan suhu ruangan sehingga menghemat penggunaan energi listrik, waktu serta tenaga untuk mengatur kecepatan putaran kipas angin.Dengan memanfaatkan NodeMCU ESP8266 sebagai pengendali. Sensor DHT11 berfungsi mengukur suhu udara didalam ruangan. Modul Relay mengendalikan ON/OFF kipas angin sesuaidengansuhu ruangan dengan kecepatan kipas, untuk suhu diatas 32oC alat dalam mode otomatis menghasilkan output kipas angin ON, apabila suhu udara dibawah 32oC maka kipas angin tersubut akan OFF walaupun ada orang yang duduk. Selain itu sistem ini dapat dikendalikan oleh aplikasi melalui smartphone untuk mengendalikan kecepatan putaran dan ON/OFF kipas angin secara manual atau otomatis, serta dapat memantau suhu udara pada ruangan. Dari hasil pengujian yang dilakukan sistem ini berkerja dengan baik, sehingga dengan dibuatnya sistem ini, pengendalian kipas angin lebih mudah karena sistem dapat mengendalikan kipas angin secara manual atau otomatis.

Abstract

Persons with disabilities with limited walking (leg disabilities) need assistive devices in carrying out life routines, especially praying at the Mosque. Current data show that 10% of the world's population or 65 million people are those with walking limitations (foot disabilities). Therefore, it is necessary to design a wheelchair that is more innovative and responsive so that the movement of people with disabilities is more assisted and flexible. This article will discuss how the author designs and manufactures wheelchairs to help people with disabilities perform prayers at the mosque. The name for the product made is Wheelchair design. To design the product the author uses the prototype method, this method is carried out by identifying problems, analyzing user needs, designing products according to user needs, making products that have been planned. This design is one of the technological development innovations in Islam as a religion that teaches its people to innovate in various scientific aspects. Besides that, this tool is actually very helpful for people with disabilities in making it easier for them to carry out worship at the mosque.

Abstract

Education personnel institutions (LPTK) are suspected of not being able to produce competent teacher candidates. The teaching materials used are still conventional, therefore information and communication technology (ICT) in the learning process is necessary to apply through digital-based learning. This research aims to: (1). identify the learning needs of the economics learning planning course desired by students. (2). test the feasibility of the developed digital-based economic learning planning teaching materials (3). tested the effectiveness of using digital-based economic learning planning teaching materials which were developed to improve students' ability to develop economic learning tools. This study used research and development (R & D) methods. The population were 115 students consisting of classes A, B and C who were attending economic learning planning courses. The sample for this study were students in the third semester of the business education study program, which consisted of two classes A and B. Class A consisted of 40 students as an experimental class and class B as a control class consisting of 40 students. The sampling technique used a random sampling technique. Data collection was carried out by conducting formative evaluations and limited trials one by one after the learning process. The results of this study indicate that digital-based teaching materials are appropriate and effective for use in planning economic learning. The t-test at α 0.05 states that the learning outcomes of planning economic lessons taught using digital-based teaching materials are higher than the group of students who are taught without digital-based teaching materials.Keywords: Digital-based teaching materials, student ability, learning toolsDOI: http://dx.doi.org/10.23960/E3J/v6i1.1-7
