Abstract

Estuary waterscapes, as a combination of freshwater and marine ecosystems, play an important role in ecology and human sustainability. Estuaries play a vital role in maintaining water quality and the fertility of the surrounding land. The social aspect of an estuary waterscape includes community interaction with the ecosystem, where the culture and social growth of coastal communities grows. Various previous studies have identified the environmental and economic impacts of estuary use on fishermen. However, the aspect that remains a question is how the environmental and economic impacts are related to social aspects in the context of fishermen's lives. We will analyze the interaction of various factors to answer how fishermen contribute to getting a decent life for fishing groups with small boats, thus clarifying previously unknown aspects. This research aims to explore information on how to manage and the amount of trash fish waste disposed of in the estuary landscape in Pagatan Besar Village and identify the condition of the quality of the estuary waters in Pagatan Besar Village. Data was collected through surveys of fishermen to find out various fishing tools and techniques, as well as collecting economic and social data through questionnaires and structured interviews. Analysis of environmental, economic and social data is carried out to predict catches, income and sustainability of fishermen's businesses. The results conclude that business sustainability has the potential to support a decent life for groups of fishermen with small boats who utilize the estuarine waterscape.

Abstract

This research aims to observe the combination effect of watering interval, and paclobutrazol toward chlorophyll, alkaloid and anthocyanin content of soybean leaves (Glycine max (L.) Merrill) growing in ultisol soil. This experimental research used a factorial complete randomized design with three replicates. There were two factors: watering interval (H1: every day, H2: 2 days and H3: 3 days) and paclobutrazol concentrations (P0: 0 ppm, P1:100 ppm, and P2: 200 ppm). The data analysed by two way Anova (Analysis of Variance) and continued with Tukey test. The result showed that watering interval and paclobutrazol had significantly interaction effect on chlorophyll, alkaloid and anthocyanin. Treatment combination which gives the highest content of chlorophyll was H2P2 (33.2 CCI), alkaloid was H3P2 (0.0177 g), and also anthocyanin was H3P2 (0.721%). It can be concluded that the application of paclobutrazol can stimulate physiological responses in the form of increasing the content of chlorophyll, anthocyanins and alkaloids so that the survival capacity of soybeans increases under drought stress conditions.

Abstract

Sambar deer (Cervus unicolor) is one of the protected animals due to its small distribution in Indonesia. Sambar deer is distributed only in Sumatra and Kalimantan islands. South Kalimantan is one of the areas doing ex-situ conservation for this animal, such as sambar deer breeding in Edupark Banjarbaru. The knowledge related to behavior, food, water, shade, and space is important to fulfill the needs of animals in developing ex-situ conservation. The study aimed to determine the daily behavior of the sambar deer, which can be scientific information for reference in the conservation effort of sambar deer, especially in ex-situ conservation activities. Observations were made directly in the field using focal animal sampling and ad libitum methods. The focal animal sampling method is used to record the daily behavior of one individual (focal individual) at the same time. The ad libitum method is to record all observed behaviors of sambar deer. The results showed that sambar deer need shady places for rest and also places to wallow to minimize their body heat.

Abstract

Cellulase is an enzyme that can break up β - (1→4) glycosidic bonds of cellulose. Generally, cellulases are classified into three major groups, i.e., endoglucanase (EC 3.2.1.4), exoglucanase (EC 3.2.1 .91), and β glucosidase (EC 3.2.1.21). Meanwhile, five isolates of tidal swamp soil have been isolated; thus, in this research step, we are acquainted with cellulase activity and the characterization of cellulase enzymes on various temperatures, pH, and specific substrates. The activity of an enzyme was measured using the modified Miller and Bradford methods to detect the specific characteristics of the isolate. The results showed that five isolates namely ATP-1 BKP-5, HAMML-2, PKL-2, and SPBKK-3 have activities 0.025 nKat.ml-1, 0.032 nKat.ml-1, 0.296 nKat.ml-1, 0.114 nKat.ml-1, and 0.087 nKat.ml-1, respectively. Furthermore, cellulase from isolates ATP 1, BKP-5, and PKL 2 have an optimum activity at pH 7,0; 50 oC. The isolate HAMML-2 has an optimum activity at pH 5,0; 60 oC. SPBK 3 has an optimum activity at pH 5,0; 50 oC. All of those isolates can degrade CMC, Avicell, and Whatman paper No.1 and retain the activity relative to the temperatures 50 and 60 0C as the characteristics of the thermostable enzyme.
