Timbulsloko adalah salah satu desa yang berada di Kecamatan Sayung, Demak. Daerah ini menjadi salah satu kawasan yang mengalami erosi secara terus menerus yang mengakibatkan luas daerahnya menjadi semakin berkurang. Dominasi mangrove yang ditemukan di desa ini adalah Rhizophora sp. dan Avicennia sp.. Tujuan dari penelitian ini adalah untuk mengetahui jenis sedimen, kerapatan mangrove serta hubungan jenis sedimen dengan kerapatan mangrove di Desa Timbulsloko, Demak. Penelitian ini dilaksanakan pada bulan April 2018. Metode penelitian yang digunakan adalah metode kuantitatif yang bersifat deskriptif dengan pemilihan lokasi penelitian menggunakan teknik purposive sampling. Lokasi sampling dibagi menjadi 3 stasiun, tiap stasiun dibagi menjadi 6 titik sampling. Hasil yang diperoleh dari jenis sedimen ketiga stasiun didominasi tekstur pasir dengan persentase pasir stasiun 1 68,78%, pasir stasiun 2 68,42%, dan pasir stasiun 3 65,91%. Bahan organik sedimen pada stasiun 1 berkisar 1,08-1,48%, stasiun 2 berkisar 0,28-1,6%, dan stasiun 3 berkisar 0,88-2,32%. Salinitas sedimen pada ketiga stasiun berkisar antara 29-30‰. Kerapatan mangrove di lokasi penelitian Desa Timbulsloko didominasi oleh jenis mangrove Avicennia sp.. Nilai kerapatan mangrove stasiun 1 berkisar 2066 - 4550 pohon/ha, stasiun 2 berkisar 2519 - 10000 pohon/ha, dan stasiun 3 berkisar 5986 - 18511 pohon/ha. Hubungan jenis sedimen dengan kerapatan mangrove jika dilihat dari analisa PCA, berdasarkan nilai loading factor kedua faktor yang terbentuk pada ketiga stasiun menunjukkan tingginya korelasi antar variabel. Sedangkan, jika dilihat dari hasil analisa regresi linear berganda menunjukkan bahwa hubungan jenis sedimen dengan kerapatan mangrove di ketiga stasiun mempunyai hubungan yang sangat kuat.  Timbulsloko is one of the villages located in Sayung District, Demak. This area became one of the areas that experienced continuous erotion which resulted the area became decreasing. The dominance of mangroves found in this area is Rhizophora sp. and Avicennia sp. The purpose of this research is to know the type of sediment texture, mangrove density and the relation of sediment texture with mangrove density in Timbulsloko village, Demak. This study was conducted in April 2018. The method of this research is descriptive quantitative method and using purposive sampling technique. Sampling area is divided into 3 stations, each station divided into 6 sampling points. The results showed that sediment types from three stations were dominated by sand texture with the percentage of station 1 sand 68.78%, station sand 2 68.42%, and station sand 3 65.91%. Sediment organic material at station 1 ranged from 1.08 to 1.48%, station 2 ranged from 0.28 to 1.6%, and station 3 ranged from 0.88 to 2.32%. Sediment salinity in three stations ranged from 29-30 ‰. Mangrove density in Timbulsloko Village is dominated by Avicennia sp.. The mangrove density values at station 1 ranged from 2066 to 4550 trees / hectare, station 2 ranged from 2519 to 10000 trees / hectare, and station 3 ranged from 5986 to 18511 trees / hectare. The relationship between the type of sediment and the density of mangroves when viewed from the PCA analysis, based on the value of loading factors from two factors formed on three stations showed the high correlation between variables. Meanwhile, when viewed from the results of multiple linear regression analysis shows that the relationship between the type of sediment and the density of mangroves in three stations has a very strong relationship.

ABSTRAKSungai Kreo merupakan suatu ekosistem yang di dalamnya terdapat beberapa komponen yang saling berinteraksi. Zat hara nitratdan fosfat biasanya terkandung di dalam air dan sedimen. Peranan nitrat dan fosfat yang terkandung dalam sedimen yang ada di sungai adalah sebagai unsur penting bagi pertumbuhan dan kelangsungan mikroorganisme dasar perairan. Tujuan penelitian ini yakni mengetahui konsentrasi nitrat dan fosfat pada sedimen, mengetahui jenis tekstur sedimen, mengetahui kelimpahan dan keanekaragaman makrozoobentos dan menganalisis hubungan konsentrasi nitrat dan fosfat pada sedimen dengan kelimpahan dan Keanekaragaman makrozoobentos di Sungai Kreo Semarang. Metode penelitian yang digunakan adalah metode eksplanatif. Penentuan stasiun sampling menggunakan teknik purposive sampling. Analisis data menggunakan uji regresi linier berganda dengan software SPSS 16. Hasil penelitian menunjukkan bahwa konsentrasi nitrat berkisar 0,14 mg/l - 0,63 mg/l. Konsentrasi fosfat berkisar 0,01 mg/l - 0,11 mg/l. Jenis sedimen stasiun I: lempung liat berpasir, stasiun II: pasir berlempung dan stasiun III : pasir. Spesies Makrozoobentos yang ditemukan adalah kelas gastropoda (Sulcospira sp, Melanoides sp, Brotia sp Annetome sp, Tarebia sp). Keanekaragaman jenis termasuk dalam keanekaragaman yang rendah (0,23 - 0,25). Hubungan konsentrasi nitrat fosfat terhadap kelimpahan dan keanekaragaman termasuk hubungan kuat (r = 0,675). ABSTRACTKreo River is an ecosystem in which there are several interacting components. Nitrate and phosphate nutrients are usually contained in water and sediments. The role of nitrate phosphate contained in sediments in rivers is an important element for the growth and survival of aquatic microorganisms.

This study aims to determine the effect of financial ratios such as current ratios, debt to assets ratio, gross profit margin on changes in earnings in food and beverage companies listed on the Indonesia Stock Exchange. The population of this research is food and beverage companies listed on the Indonesia Stock Exchange. The sampling technique was using purposive sampling method. Based on purposive sampling from 40 companies, it was obtained a sample of 19 companies that met the criteria. The research data is secondary data obtained from the Indonesian Stock Exchange (www. Idx.co.id) and ICMD 2016-2017. Testing the research hypothesis used multiple linear regression analysis techniques (Multiple Regression Model), with the application tool SPSS (Statistical Product and Service Solutions). The results of this study indicate that there is no significant effect between Current Ratio, Debt to Assets Ratio and Gross Profit Margin on partial changes in earnings, so it can be concluded that the first hypothesis is rejected. Likewise, the simultaneous test of Current Ratio, Debt to Assets Ratio, Gross Profit Margin simultaneously or together is unable to explain changes in the dependent variable, namely changes in earnings.
