Sungai Banjir Kanal Barat dan Banjir Kanal Timur merupakan sungai besar yang berperan dalam mempengaruhi nilai kualitas perairan Semarang. Sungai ini membawa material dan limbah yang berasal dari darat kemudian mengalir ke laut melalui muara sungai. Penelitian ini bertujuan untuk mengetahui nilai konsentrasi zat padat tersuspensi (MPT) dan fosfat serta pola distribusinya. Penelitian ini dilaksanakan pada bulan Februari 2019 dengan menggunakan metode deskriptif kuantitatif. Metode penentuan lokasi menggunakan purposive sampling pada 22 stasiun yang dapat merepresentasikan wilayah muara dan laut. Penentuan MPT secara gravimetri dan fosfat menggunakan metode asam askorbat. Hasil konsentrasi MPT berkisar antara 50-290 mg/L dan fosfat 0,95-0,16 mg/L. Pola distribusi secara horisontal MPT menunjukkan lebih tinggi di daerah dekat pantai dan pola sebaran vertikal menunjukkan lebih tinggi di permukaan (0,2 m) dibanding di bagian bawah (0,8 m). Pola sebaliknya ditemukan pada sebaran fosfat dengan nilai lebih tinggi di dasar dan pola sebaran spasialnya menunjukkan konsentrasi tinggi ditemukan di wilayah timur yaitu di Muara Sungai Banjir Kanal Timur. Sungai Banjir Kanal Timur memberikan kontribusi yang besar terhadap unsur hara fosfat terlarut. The Banjir Kanal Barat and Banjir Kanal Timur River are major rivers that play a role in influencing the quality value of Semarang waters. This river carries material and waste originating from the land and then flows out to the sea through the river mouth. This study aims to determine the concentration value of suspended solids (MPT) and phosphate and the distribution pattern. This research was conducted in February 2019, using descriptive quantitative methods. The method of determining the location uses purposive sampling at 22 stations that can represent the estuary and sea areas. Gravimetric and phosphate determination of MPT using the ascorbic acid method. The results of MPT concentrations ranged from 50-290 mg / L and phosphate from 0.95 to 0.16 mg/L. Spatial distribution of MPT shows a high concentration in the coastal area and vertically, the distribution is higher at the surface (0.2 m) than at the bottom (0.8 m). This pattern is different from the phosphate which is found to be higher at the bottom with its spatial distribution showing a high concentration in the eastern region, namely in the estuary of Banjir Kanal Timur. This estuary of Banjir Kanal Timur has a large contribution to phosphate ions.

It is known that the bacterial symbionts are symbiotic with gastropods Conus miles has the potential to be able to produce antibacterial compounds against bacterial MDR (Multi Drug Resistant). Information found previously from bacterial symbionts and isolation based on screening results, the size of the zone of inhibition and inhibitory properties against several types of bacteria tests showed that isolates derived from Conus miles Gastropoda symbionts characterized by kinship rate of 98% in bacteria Pseudoalteromonas sp. The research objective was to determine the characteristics of the bacterial symbiont bioactive compounds associated with the type of mollusk Conus miles. The study was conducted three phases namely the isolation and purification of bacteria; characterization of isolates identified through test results on the reaction of physiological and biochemical tests, as well as the identification of secondary metabolites by GC-MS method QP2010S Shimadzu. The results showed that the bacterial symbiont isolates had a number of compounds with a percentage of the highest peak to the lowest compound the compound, Acetic acid (CAS) ethylic acid (35.22%); propanoic acid, 2-methyl-(CAS) Isobutyric acid (11.78%); Iso -valeric acid (9:38%), butanoic acid, 2-methyl-(CAS) 2-methylbutanoic acid (4.74%) and 1,2-Benzenedicarboxylic acid, dioctyl ester (CAS) Dioctyl phthala (4:36%). The results concluded that the bacterial symbiont isolates obtained in this study provide information on the results of potentially new antibiotics.

The potential of mangove fruit as a food source has not been known yet. Mangove is a potential material to be used as a food substitute, one of which is the process of making flour. One part of the Mangove is used for the manufacture of flour is the fruit of mangove A.marina. Toxins such as HCN in fruit may cause constraint in food processing, so it needs to be removed. The ways that can be done by immersion and boiling them with rice husk ash. Rice husk ash is material that is expected to absorb HCN as toxin in fruit. This research used Completely Randomized Design (CRD) factorial pattern consisting of two factors treatments with three replicates by 6 hours immersion time (4, 8 and 12 replications) and ash contents (5, 10, 15% W). Data were analyzed by two-way ANOVA using SPSS. The results showed that treatment with several concentrations of ash boiling and long water immersion to give a significant influence on levels of HCN A.marina mangove fruit flour. Treatment with boiling 15% ash content and 6 hours of water immersion to 12 replications provides the best results of the HCN content of fruit and flour mangove mangove A.marina

Kota Pekalongan dilalui oleh sungai Slamaran yang menjadi tempat masuknya fosfat dari darat ke laut. Fosfat adalah nutrient yang terkandung dalam bahan organik dari limbah domestik maupun pertambakan yang mempengaruhi kesuburan perairan muara Sungai Slamaran. Konsentrasi fosfat di perairan dapat dipengaruhi oleh material padatan tersuspensi (MPT). Penelitian ini bertujuan mengkaji persebaran konsentrasi fosfat dan MPT serta mengkaji hubungan antara sebaran fosfat dan MPT di muara sungai Slamaran, kota Pekalongan. Data lapangan diambil secara in situ. Sampel air dianalisis di laboratorium. Analisis fosfat menggunakan metode yang digunakan oleh Strickland dan Parson (1968). Analisis MPT menggunakan metode gravimetri. Peta sebaran konsentrasi fosfat dan MPT dibuat dengan software ArcGis. Arus permukaan laut dimodelkan dengan software Mike 21 selanjutnya divalidasi dengan nilai RMSE dan MAE. Analisis korelasi Pearson digunakan untuk menentukan korelasi antara konsentrasi fosfat dan MPT. Hasil penelitian menunjukkan bahwa nilai konsentrasi fosfat memiliki rentang 0.44–1,84 µM, dan konsentrasi MPT memiliki rentang 56-152 mg/L. Berdasarkan peta persebaran fosfat dan MPT di perairan muara Sungai Slamaran, diduga bahwa persebaran fosfat dan MPT mendapat pengaruh dari masukan sungai dan tambak udang yang berada di muara sungai Slamaran. Hasil analisis korelasi menunjukkan korelasi yang tidak cukup kuat antara sebaran konsentrasi fosfat dengan sebaran MPT. Pekalongan city is crossed Slamaran River which is entry point phosphate from the land to the sea. Phosphate is a nutrient contained in organic material from domestic waste and aquaculture which affects the productivity of the waters of Slamaran river estuary. Phosphate concentrations in waters can be influenced by suspended solids (TSS). The aims of this study were to determine concentration of phosphate and TSS distribution and to examine correlation between phosphate and TSS concentrations in Slamaran River estuary. In situ data were taken at Slamaran River estuary. Water samples were analyzed at laboratory. Phosphate concentration analysis used method by Strickland and Parson (1968). TSS concentration analysis used gravimetric method. Distribution of Phosphate and TSS concentration were mapped using ArcGIS software. Ocean surface currents was numerically modeled used Mike 21 software then validated with RMSE and MAE methods. Pearson correlation method was used to analyzed correlation between phosphate and TSS concentration. The results showed that phosphate concentration were ranged from 0.44–1,84 µM mg/L and TSS concentration were ranged from 56-152 mg/L. Based on distribution map of phosphate and TSS in the Slamaran River estuary, it was predicted that phosphate and TSS distribution influenced by inputs from the river and shrimp ponds along the estuary Slamaran river. Results of the correlation analysis showed that correlation between phosphate and TSS concentrations distribution was not strong enough.
