Abstract

This study aims to analyze the process of soil formation on overburden material in the reclamation area in 2013 (9 years), 2015 (7 years), and 2018 (4 years) to support the success of sustainable reclamation, and analyze the relationship between planting age, morphology and climate conditions in the study area that can affect the process of soil formation in the overburden. The research was conducted at a coal mining company located in Tanah Bumbu Regency, South Kalimantan Province. The research method used was descriptive quantitative. Data collection was done by making a test trench and taking soil profile data which includes topsoil thickness, intermediate layer, and overburden. Soil texture, soil color, and data on roots that penetrated the soil were also recorded and analyzed. The results of the test trench analysis showed that the process of soil formation in the overburden began to occur in the reclamation area in the 9th year (2013). The indicator found lateral roots in the soil layer at a depth of 40-60 cm which is an overburden layer with gray soil color. The correlation test showed a strong relationship between soil acidity (pH) and the year of planting (r2 = 0,74). The relationship between organic C elements and the year of planting (r2 = 0,68). The element N in the soil has a very strong relationship with the year of planting (r2 = 0,92). The next element was P2O5 in the soil having a moderate relationship (r2 = 0,46) and K2O elements had a strong relationship (r2 = 0,75). The results of soil chemical analysis and also soil texture showed that the soil fertility status at the study site was in low condition. This study concluded that the process of soil formation in overburden was found in the planting year area of 2013 or year 9, with indicators such as the appearance of roots in the overburden area at a depth of 20 - 40 cm, whereas in 2015 and 2018 no roots were found in the overburden. Climatic and morphological conditions accelerated the process of soil formation in the overburden because this very wet condition accelerated the process of leaching nutrients to the surface layer of the reclamation area. The process of weathering in the soil, especially in overburden, will cause plant roots to enter the overburden layer by bringing nutrients produced by trees, undergrowth, and litter to the research area.

Abstract

Coral reef, the most diverse and highly valuable marine ecosystem, may be influenced by bleaching. This study aimed to determine the effect of turbidity on the severity of coral bleaching and mortality due to thermal stress and high solar irradiation caused by the 2015 El Niño event. Coral colonies in eighteen permanent bleaching belt transects (50 m x 1 m) in six sites were observed from June to November 2015, coinciding with the 2015 El Niño event. Environmental factors: water depth, sea surface temperature (SST), salinity, turbidity, sedimentation and total suspended solid (TSS) were measured on the same transect. The results of the study showed that the 2015 El Niño event was a major disaster for reefs on the southeast coast of the Kalimantan. Of total colonies (N = 12,954), 45.4% of colonies were bleached and 14.7% of colonies died during the period of July to November 2015. Turbidity, TSS, and sedimentation were negatively correlated with the bleaching mortality index (BMI). Coral bleaching in clear and deep waters occurred earlier and increased rapidly compared to that in turbid waters. However, the severity of coral bleaching in the turbid zone increased dramatically when the turbidity dropped to <3 NTU. Turbidity >5 NTU could provide shade, in which the proportion of dead corals was only 3.5%. The severity of coral bleaching in the turbid zone is not solely due to thermal stress and solar irradiation; it may also be influenced by a history of exposure to high turbidity and low salinity.

Abstract

Penelitian ini bertujuan untuk mengetahui tingkat kesuburan perairan yang dilaksanakan di kolong Kecamatan Cempaka Kotamadya Banjarbaru Provinsi Kalimantan Selatan dan di Laboratorium Kualitas Air Fakultas Perikanan dan Kelautan. Kesuburan perairan berdasarkan pada kelimpahan plankton serta indeks keanekaragaman, keseragaman dan dominasi. Pengambilan sampel dilakukan terhadap 3 stasiun berdasarkan lama pascatambang yaitu selama 2 tahun (stasiun 1), 7 tahun (stasiun 2) dan 10 tahun (stasiun 3). Hasil penelitian menunjukkan bahwa berdasarkan kriteria kelimpahan plankton, perairan kolong pascatambang 2, 7 dan 10 tahun tergolong sebagai perairan dengan tingkat kesuburan sedang. Berdasarkan indeks keanekaragaman, stabilitas struktur komunitas plankton setiap stasiun tergolong sedang dan dengan kesuburan sedang. Indeks keseragaman, penyebaran struktur komunitas plankton pada stasiun 1 dan 2 adalah sangat merata dengan katagori sangat baik, sedangkan pada stasiun 3 tergolong lebih merata dengan kategori baik. Indeks dominasi plankton pada ketiga stasiun pengamatan adalah rendah This Research aims to determine the level of water fertility conducted under the subdistrict Cempaka Kotamadya Banjarbaru South Kalimantan Province and the Water Quality Laboratory Faculty of Fisheries and Marine. Water fertility is based on plankton abundance as well as indices of diversity, uniformity and dominance. Sampling was conducted on 3 stations based on post-mining time ie for 2 years (station 1), 7 years (station 2) and 10 years (station 3). The results showed that based on the criteria of plankton abundance, the waters of the post-mined colonies 2, 7 and 10 years were classified as waters with moderate fertility levels. Based on the index of diversity, the stability of the plankton community structure of each station is moderate and with moderate fertility. Uniformity index, the distribution of plankton community structure at stations 1 and 2 is very uniformly with a very good category, while at station 3 is more evenly distributed with the good category. The plankton dominance index at the three observation stations is low.

Abstract

Perubahan derajat keasaman (pH) pada perairan dalam jumlah tertentu dapat menyebabkan kematian pada organisme akuatik yang hidup didalamnya. untuk mengatasinya terdapat berbagai cara yang dapat dilakukan untuk mengontrol derajat keasaman perairan. Salah satunya adalah dengan penambahan baking soda pada perairan untuk menetralkan derajat keasaman perairan. Penelitian ini bertujuan untuk mengetahui apakah baking soda dapat menstabilkan pH air tempat hidup benih ikan Nila serta Pengaruhnya terhadap tingkat mortalitas benih ikan Nila. Penambahan baking soda sebesar 0,50 g/L merupakan perlakuan yang efektif dalam kemampuannya untuk menteralkan pH perarian dengan kenaikan pH sebesar 1,88 dan tidak terdapat kematian pada semua perlakuan pada tiga kali pengulangan. Changes in the degree of acidity (pH) in water in a certain amount can cause death in aquatic organisms that live in it. To overcome this, there are various ways that can be done to control the degree of acidity of the waters. One of them is the addition of baking soda to the waters to neutralize the acidity of the waters. This study aims to determine whether baking soda can stabilize the pH of the water where tilapia fingerling lives and its effect on the mortality rate of tilapia fingerling. The addition of baking soda of 0.50 g / L is an effective treatment in its ability to neutralize the pH of water with an increase in pH of 1.88 and there is no death in all treatments on three repetitions.
