Abstract

Salt is a product from marine resources which is a strategic commodity as an industrial raw material and food for the community. However, the condition of national salting is currently still not conducive, this is because salt production, both quantity and quality, is still insufficient and sufficient to meet national salt needs. This research aims to compare the effectiveness of traditional techniques and heating techniques in aging seawater for the seawater crystallization process in making salt. With this research, it is hoped that there will be the latest technological innovations to speed up the time for making salt with maintained quality, good quantity and profit so that national salt needs can be met. From this research it can be concluded that the use of heating techniques is more effective than traditional techniques because it can minimize the aging time of sea water and can increase the quantity of salt produced.

Abstract

Sea water intrusion is a process where sea water is mixed with underground water around the coast, causing the ground water to become salty because it is contaminated by sea water which is rich in salt. Sea air that enters the ground causes the air to become unfit for consumption and causes the land to become unproductive for planting. People in the Pakis Jaya area, Karawang face difficulties, especially regarding land use for agricultural activities. This is because the land used for cultivating plants is saline soil with a high salt content. Phytoremediation is a method used to clean air or soil contaminated with pollutants, by using the ability of plants to absorb these substances. Cynodon Dactylon and lolium Perenne Brightstar plants are a type of grass that can be used to reduce high salt levels in the soil because these plants are able to live in places with high salinity and also have the ability to reduce salinity by absorbing chloride ions in it. The methods used in this research consisted of: Sampling Process, Plant Acclimatization Stage, Salinity Concentration Test before and after planting grass in Soil Media. The test results showed that the salt content in the soil before planting was 19.20 dS/m and after planting it was 0.02-0.03 dS/M.

Abstract

Arus laut merupakan pergerakan massa air secara horizontal yang dapat disebabkan oleh beberapa faktor seperti tiupan angin, perbedaan densitas maupun pasang surut laut. Arus laut merupakan parameter hidro-oseanografi yang dinamis dan mempunyai peran penting dalam transpor nutrien, larva, material, dan lain sebagainya. Tujuan penelitian ini untuk mengetahui karakteristik arus Laut Jawa di beberapa kedalaman. Metode penelitian adalah metode kuantitatif berupa analisis data dan deskriptif. Data yang digunakan diperoleh dari pengukuran arus mengunakan alat Vessel Mounted ADCP (Acoustic Doppler Current Profiler) yang dilakukan pada bulan Desember 2019 dengan menggunakan kapal riset Pusat Riset Oseanografi-Badan Riset dan Inovasi Nasional. Dari hasil pengolahan dan analisa data diperoleh di Laut Jawa kecepatan arus minimal rata-rata nya adalah 0,003 m/s sedangkan kecepatan arus maksimal rata-rata nya adalah 0,393 m/s. Kecepatan arus ter lambat adalah 0.001 m/s terjadi pada kedalaman 30 m sedangkan kecepatan arus tercepat adalah 0,410 m/s terjadi pada kedalaman 35 m. Secara umum arah arus yang terjadi di Laut Jawa pada monsun barat adalah menuju timur laut.

Abstract

The need for electrical energy by society and industry has encouraged research to build electricity generation from new and renewable energy. The sea is a source of renewable energy, especially ocean wave energy. Mechanics for the design and construction of a floating system ocean wave power plant is a power plant that utilizes ocean wave energy with a two-floating system equipped with various components aimed at producing electric power. The aim of this research is to design and manufacture the mechanics of a sea wave power plant. The techniques used in making mechanical components are welding, cutting, smoothing, drilling and dynamo installation. The results obtained from this research are to design and build a mechanical system to produce ocean wave electricity. As a result of equipment testing in the mechanical systems lab, this wave power generator succeeded in lighting electric lights with an electric current output of around (0.01 – 0.02) Ampere and a voltage of (2.70 – 4.90) Volts with a float height of between (30 – 100) cm.

Abstract

Mangroves are one of the ecosystems that grow in places that are influenced by the around the coast and river mouths. The technique of planting and maintaining mangrove seedlings varies from place to place depending on the media and conditions in the field. The purpose of this study was to compare the growth of mangrove species Rhizophora spp on two different nursery media, namely polybag and hydroponic media. This research was conducted in Karimunjawa National Park, Central Java, with an experimental research method. The results showed the growth rate of mangrove seedlings using polybag media was an average of 0.64cm per fortnight, while with hydroponic media it was 0.44cm per fortnight. The first leaf growth with polybag media occurred in the fifth week after planting while for hydroponic media the leaves grew in the sixth week. The survival rate on polybag media is 92.31%, while in hydroponic media it is 84.61%

Abstract

Salinitas adalah tingkat keasinan atau kadar garam yang terlarut dalam air, yaitu jumlah gram garam yang terlarut untuk setiap liter larutan. Pengukuran salinitas secara berkala akan memberikan dampak yang positif terhadap suatu lingkungan karena salinitas adalah salah satu faktor penting dalam menilai kondisi suatu perairan. Pengukuran salinitas dapat menggunakan alat Conductivity Temperature Depth (CTD, alat ini digunakan juga untuk mengukur parameter air lainnya seperti suhu, tekanan, kedalaman dan densitas. Tujuan penelitian ini adalah untuk mengetahui karakteristik salinitas dan pola sebaran salinitas pada berbagai kedalaman di perairan Pulau Sumba, Nusa Tenggara Timur. Pengambilan data dilakukan dengan menggunakan alat Conductivity Temperature Depth (CTD yang dilaksanakan bersama dengan Pusat Riset Oseanografi, Badan Riset dan Inovasi Nasional (BRIN). Hasil pengolahan dan analisa data diperoleh di perairan Pulau Sumba salinitas tertinggi terdapat pada kedalaman 200m dengan nilai 34,57 psu dan nilai salinitas terendah terdapat pada kedalaman 5m dengan nilai 34,02 psu. Adapun salinitas rata-rata di perairan Pulau Sumba adalah salinitas maksimum adalah 34,54 psu dan salinitas minimum adalah 34,14 psu.
