Abstract

This study aimed to verify the effect of relative humidity during incubation ofduck eggs in the incubator on the rate of decline in egg weight, hatching day old duck weight, length and hatching eggs energy difference duck. Duck eggs taken from the poultry business in Meunasah Krueng, water fence, Lambaro, Aceh Besar. Then each egg was placed in an incubator unit in the three experimental groups, namely low humidity (57/58% RH), intermediate humidity (67/68% RH) and high humidity (71/72% RH). Incubation process done manually with temperature 38 oC incubator. Eggs were coded X and O adjacent to facilitate marking a reversal in current twice a day. Primary data retrieval from the first day until the fifteenth day by weighing the eggs and using electronic scales. Changes in egg weight reduction on the fifteenth day following (10.666%), (3.853%) and (2.859%) for the treatment of low humidity, intermediate andhigh, then the day of hatching eggs weigh hatching day old duck also showed that the weight is also affected by incubation and humidity differences by ANOVA analysis it can be concluded that the changes in egg weight reduction greatly influence the hatching duck weight difference and the difference so long incubation energy hatching day old duckling have more energy at low humidity (57/58% RH).

Abstract

Energi matahari sangat dibutuhkan oleh seluruh makhluk hidup untuk berbagai macamkeperluan kehidupan. Pemakaian dengan jumlah yang tepat untuk setiap makhluk hidupmerupakan usaha untuk kelangsungan hidupnya. Tetapi apabila berlebihan akan sangatmengganggu kenyamanan thermal hidupnya. Banyaknya keluhan dari masyarakat yangmengatakan bahwa keadaan cuaca semakin panas khususnya di perkotaan, keadaan ini terjadiakibat tidak seimbangnya banyak bangunan dan jumlah tanaman yang ada sehingga penyerappanas radiasi yang dipancarkan matahari berkurang drastis. Untuk mengurangiketidaknyamanan thermal lokal di Banda Aceh dan sekitarnya dilakukan dengan caramemperbanyak pepohonan, dimulai dari lingkungan pekarangan rumah masing-masing, tamankota maupun taman-taman pekarangan rumah, sehingga akan tercipta kenyamanan thermal dilingkungan sekitarnya, karena fungsi tanaman adalah menguraikan karbondioksida menjadiOksigen serta menyerap panas matahari yang digunakan pada proses fotosintesis. Untukmemilih tanaman yang akan di tanam di pekarangan rumah supaya dapat mengurangi panas,diperlukan pengetahuan tentang kemampuannya tanaman dalam menyerap panas matahari.Karena itulah perlu kajian untuk mengetahui jenis tanaman yang paling banyak menyerappanas akibat radiasi matahari. Tanaman yang dikaji adalan tanaman yang biasa ditanam olehmasyarakat disekitar rumahnya seperti tanaman melinjo, jeruk nipis, mangga dan jambu.Manfaat yang diharapkan dari penelitian ini adalah dapat memberikan informasi bagimasyarakat khususnya di Banda Aceh tentang kemampuan masing-masing tanaman dalammenyerap panas untuk kenyamanan thermal di linkungan perumahan, dan tanaman mana yanglayak dan bagus untuk menjadikan suasana rumah sejuk dan nyaman terhadap panas.Kata kunci: panas, matahari, tanaman, kenyamanan termalSolar energy is needed by all living beings for various purposes of life. The use of the rightamount for every living being is an attempt for survival. But it would be very disturbing ifexcessive thermal comfort of his life. The number of complaints from people who say that theweather is getting hot, especially in urban areas, this situation occurs due to an imbalance ofmany buildings and the number of existing plants so that the heat absorbing radiation emittedby the sun is reduced drastically.To reduce the local thermal discomfort in Banda Aceh and itssurroundings is done by multiplying the trees, starting from the environment each home yard,city park and gardens, that will create thermal comfort in the surrounding environment, becausethe plant is to break the functions of carbon dioxide into oxygen and absorb solar heat used inthe process of photosynthesis.To choose of the plants types that will be planted in the homeyard in order to reduce the heat, the necessary knowledge of the plant's ability to absorb thesun's heat. It is needed the study of how to know the types of plants that absorb most of theheat due to solar radiation. Plants were assessed are plants that commonly grown by thepeople around her house like melinjo plants, lemon, mango and guava. The expected benefitsof this research is to provide information for people, especially in Banda Aceh on the ability ofeach plant to absorb heat for thermal comfort in residential environments and plants which areworthy and good to make the house cool and comfortable atmosphere to heat.Keywords: heat, sun, plants, thermal comfort

Abstract

Data from the Ministry of Maritime Affairs and Fisheries shows that Aceh Province, with a coastline length of 2666.3 km stretching from east to west, holds a variety of marine wealth, both fisheries and other natural resources. The province of Aceh has archipelagoes spread over Aceh Besar and Aceh Singkil. The archipelago areas in Aceh Besar are Aceh Island, Rice Island and Nasi Island. The availability of electricity in the archipelago, namely on the island of Aceh, is only at 18.00 - 22.00 and 5.00 - 8.00. Because of this, a study was carried out on using solar electricity to drive compressors in cold storage. This study aims to determine the solar energy capacity and photovoltaic area required for cold storage with a capacity of 100 kg of fish, determine the temperature of the cold storage when operating with and without load and determine the coefficient of performance (COP) of cold solar storage over time. This research was conducted experimentally to test the use of cold storage for storing fish. The results showed that the cold storage temperature was -15.9 ℃ with an average current of 0.87 A, a voltage of 226.02 V and a power of 124.72 W when operating without load, while with a load, the temperature was -3.1 ℃ with an average current is 0.890 A, voltage is 225.88 V, and power is 127.96 W. The ideal COP value is greater than the actual COP value (8.07 2.69). To run cold storage using solar energy, a battery with a capacity of 120 Ah is required until it reaches a temperature of -3.1 ℃ lasts 2 – 3 days with 40% remaining battery usage and is recharged every day

Abstract

Solar power plants can be applied in various forms of installation, either centralised or distributed, with each configuration system installation being either on-grid or off-grid. Samudra University plans to install a solar power plant for environmentally friendly applications and energy savings. The purpose of this study is to investigate the feasibility and benefits of Samudra University installing solar power generation capacity using a single-owner system on campus using SAM (System Advisor Model) applications using two axes with PV energy. The method used is to model the photovoltaic results with the System Advisor Model (SAM), which can develop new renewable energy photovoltaics. The use of solar energy as a producer of electrical energy in buildings at the ocean university by using the System Advisor Model application on the Single Owner (Grid) system in collaboration with local electricity (PLN) to continue the energy needs produced as much as 32,652,394 kWh will cost Rp. 372,864,450,000, and with an area of 105,179.9 m2 or ± 11 hectares of the total area of 49.8 hectares, it only uses ± 20% of the total area
