Abstract

Pada umumnya pembuatan garam secara tradisional menggunakan teknologi evaporasi air laut   memerlukan waktu 20 hari per panen garam, sedangkan dengan metode Maduresse Berisolator memerlukan waktu 12 hari per panen garam. Tujuan penelitian ini adalah untuk melakukan inovasi teknologi evaporasi air laut dengan uji coba aplikasi teknologi tepat guna dalam percepatan pembuatan garam dengan Metode Sprinkle Bertingkat. Penelitian ini dilakukan selama 3 bulan mulai bulan Agustus sampai dengan bulan Oktober 2019 sebanyak 30 kali ulangan dan menghasilkan data rata – rata 3 oBe menjadi 9,78 oBe per hari.  Hasil penelitian ini dengan Metode Sprinkle Bertingkat dalam waktu 6 hari menghasilkan kristal garam atau lebih cepat 6 hari per panen, jika dibandingkan dengan Metode Maduresse Berisolator. Percepatan pembuatan garam ini terjadi karena adanya inovasi teknologi dengan menambahkan alat berupa sprinkle yang berfungsi menyemprotkan air laut ke udara sehingga mempercepat terlepasnya H2O dari air laut dan mempercepat terbentuknya kristal garam. Dengan demikian dapat disimpulkan bahwa Metode Sprinkle Bertingkat dapat diterapkan untuk mempercepat terbentuknya kristal garam, sehingga metode ini direkomendasikan sebagai inovasi teknologi dalam meningkatkan produksi garam.

Abstract

Water quality is a limiting factor of life for aquatic biota, especially biota that lives in a pond. Therefore, water quality management is very necessary so that cultivation activities, especially ponds can continue and do not cause negative impacts on the surrounding environment. Various factors can decrease the water quality of aquaculture ponds one of which is from the remnants of feed and fish manure. Feed is one of the contributors to the dissolved organic matter in the cultivation pond. Maggot or black shoulder fly larvae are one of the alternatives that can be used as fish feed. Maggot has a high animal protein content of 30-45%, so it is very effective to be used as an alternative to additional feed in fish farming. The purpose of this research is to find out the difference in pond water quality between ponds by using maggot and pond feed by using pellet feed. The data taken in this study is primary data using the Complete Randomized Design (RAL) method with 3 treatments and 3 replays in each treatment. These treatments include Full Maggot Control (MU), 50% pellet, and 50% maggot (PU). Data obtained include; ammonia. Nitrites, and nitrates. The results showed that the average final value of ammonia, nitrite, and nitrates respectively treatment is KU ( 0.22 mg / L, 0.44 mg/L, 3.667 mg/L), PU (0.022 mg/L, 0.042 mg/L, 3.433 mg/L), MU (0.046 mg/L, 0.028 mg/L, 2.653 mg/L). The results illustrate the conclusion that the provision of maggots as an alternative and additional feed can improve the quality of aquaculture water.

Abstract

Water is one of the basic needs for human life, including for people living on the coast. It is difficult to get clean water for consumption because most coastal areas are affected by sea conditions that have high salinity. In order to be consumed, the saline water must be desalinated. Desalination is a process to convert saline water into fresh water. One such desalination technology is using reverse osmosis (RO). The purpose of this study was to determine the process of desalination of seawater into freshwater using the seawater reverse osmosis (SWRO) method. The method used in this research is observation, which is to see directly the stages of the desalination process of seawater into fresh water. The data was obtained in the form of primary data from observations and secondary data from the literature to support primary data. Analysis of the data used in the form of descriptive analysis by describing each stage carried out in the SWRO process. The results showed that the seawater desalination process using SWRO technology had 14 stages. These stages include; intake, raw water pump, raw water reservoir, UF feed pump, Automatic screen, ultrafiltration, UF water reservoir, RO feed pump, HPP & booster, RO membrane, RO water reservoir, permeate pump, chlorine analyzer, product water. In developed and developing countries, SWRO units have been widely used, because by processing seawater into freshwater, there are many benefits for the life cycle and it is environmentally friendly. It also maintains underground fresh water so that it can provide plant life, and trees that provide us with clean oxygen for our lives.

Abstract

A sensor called an ultrasonic sensor works by converting electrical quantities into physical quantities (sound) and vice versa. An Arduino Uno is required to activate the system's ultrasonic sensor. The reservoir's water level is determined using ultrasonic sensors. The purpose of this investigation is to learn how to put together, program, and utilize the HC-SR04 Arduino Uno ultrasonic sensor with the Arduino IDE (Integrated Development Environment) application. Controlling the water in the desalination system is required so that the water entering the reservoir does not waste or overflow and pollute the desalinated water. An ultrasonic sensor is attached to a seawater desalination system using the evaporation method, and the sensor is put on the edge of the evaporation pond in order to conduct experimental testing of the ultrasonic sensor on the device. The desalination tool can operate more efficiently and under control with the help of the HC-SR04 ultrasonic sensor by automatically filling the water in the evaporation pond. The sensor will automatically supply the water shortage when the seawater evaporates. Results of experimental observations made with the HC-SR04 ultrasonic sensor on an evaporation bath with three water filling cycles are available. so that after 7 days, 13% of the volume that was filled in the evaporation basin has evaporated.

Abstract

Phytoplankton are unicellular algae plants found in marine and freshwater ecosystems. The presence of phytoplankton in waters plays an important role in the cultivation process. However, not all types of phytoplankton can have a good impact on cultivation ponds, this is because there are types of phytoplankton that are toxic and can cause death to the biota in the pond. This observation regarding phytoplankton aims to determine the structure of the phytoplankton community in cultivation ponds and determine the water quality in cultivation ponds through the saprobic coefficient value. The method used is a survey by determining sampling locations using the simple random sampling method. The data obtained were analyzed using the diversity index, dominance index, uniformity index and saprobic coefficient index. Observation results show that the Phytoplankton Community Structure in freshwater fish cultivation ponds at the Karawang Marine and Fisheries Polytechnic has 4 classes, namely Chlorophyceae (6 genera), Cyanophyceae (3 genera), Bacillariophyceae (6 genera) and Dinophyceae (2 genera) with abundance. Ranged from 7,500 cells/mL to 305 cells/mL. The diversity index shows moderate population stability with a high uniformity index and the absence of species dominance. The saprobity index shows values ranging from lightly to moderately polluted so that the cultivation ponds at the Karawang Marine and Fisheries Polytechnic are still classified as good and can be used for cultivation activities. However, it is necessary to always monitor and evaluate so that these conditions are maintained and do not become heavily polluted.

Abstract

Kerapu cantang merupakan hasil perkawinan silang antara indukan kerapu macan betina (Epinephelus fuscoguttatus) dengan indukan kerapu kertang jantan (Epinephelus lanceolatus) dengan tujuan untuk mendapatkan varietas baru yang pertumbuhannya lebih cepat dari pada induknya. Penelitian ini bertujuan untuk mengetahui performa pertumbuhan, nilai Survival Rate, dan kondisi parameter kualitas air benih kerapu cantang pada fase pendederan. Metode yang digunakan yaitu metode survei dengan penentuan pengambilan sample menggunakan metode Simple Random Sampling dengan mengukur berat dan panjang ikan. Data diperoleh melalui pengamatan selama 4 minggu. Setiap sampling ikan kerapu cantang diambil 10 ekor kemudian diukur panjang dan beratnya. Data yang disajikan dalam bentuk gambar, tabel dan diagram. Hasil pengamatan menunjukkan bahwa rata-rata nilai panjang mutlak sebesar 3,88 cm, rata-rata nilai berat mutlak sebesar 10,23 gram, Survival Rate sebesar 85,94%. Berdasarkan hasil tersebut dapat diketahui bahwa performa ikan kerapu cantang cukup baik dengan tingkat kelulushidupan yang juga masih diatas baku mutu yaitu ± 80%. Parameter kualitas air yang diukur meliputi suhu (28-29ºC), salinitas (33-34 ppt), pH (8,13-8,30), dan DO (5,32-5,96 mg/L), hasil pengukuran kualitas air tergolong baik, sebab masih dalam baku mutu air untuk budidaya benih kerapu cantang berdasarkan SNI. Nilai pertumbuhan ikan kerapu cantang masih sesuai dengan SNI 8036.2: 2014 untuk fase pendederan, dengan tingkat kelulushidupan yang cukup tinggi disebabkan oleh faktor daya tahan tubuh benih ikan kerapu cantang.   Cantang grouper is the result of crossbreeding between female tiger grouper parents (Epinephelus fuscoguttatus) with male tiger grouper parents (Epinephelus lanceolatus) with the aim of obtaining a new variety that grows faster than its parent. This research aims to determine the growth performance, Survival Rate value, and condition of water quality parameters for cantang grouper seeds in the nursery phase. The method used is a survey method by determining sampling using the Simple Random Sampling method by measuring the weight and length of the fish through observations for 4 weeks. For each sampling, 10 cantang grouper fish were taken and then their length and weight were measured. Observation results are presented in the form of pictures, tables and diagrams. The observation results show that the average absolute length value is 3.88 cm, the average absolute weight value is 10.23 grams, the survival rate is 85.94%. Based on these results, it can be seen that the performance of cantang grouper fish is quite good with a survival rate that is still above the quality standard, namely ± 80%. Water quality parameters measured include temperature (28-29ºC), salinity (33-34 ppt), pH (8.13-8.30), and DO (5.32-5.96 mg/L), the results of quality measurements The water is classified as good, because it is still within the water quality standards for cultivating cantang grouper seeds based on SNI. The growth value of cantang grouper is still in accordance with SNI 8036.2: 2014 for the nursery phase, with a fairly high survival rate due to the body resistance factor of cantang grouper seeds.
