Abstract

Groundnut (Arachis hypogaea L.) is a crop plant that has an essential role in several food industries because it has high nutritional content, especially protein, and fat. One of the limiting factors in efforts to increase peanut production is the disturbance of plant-disrupting organisms (PDO). Preventive efforts that can be made to minimize yield losses due to pest problems in peanut plants include inventory activities and direct observations in the field. This study aims to assess the biological aspects of important diseases in peanut plants as an initial step in making pest control decisions. Observations were conducted on a 748 m2 farmer's field in Purangi Village, Sendana Sub-district, Palopo City. The field was divided into two main plots, without using maize barrier (B0) and using maize barrier (B1), and six subplots (P1-P6). Groundnut disease symptoms were determined through identification based on the signs and symptoms of the attack. Disease symptoms found in peanut plants were chlorosis, necrosis, spotting, mosaic, curling, and wilting. Mosaic and necrosis symptoms were the most dominant symptoms with the highest frequency of occurrence at 50 times, while chlorosis, curling, stripes, and wilting symptoms were the lowest symptoms with the least frequency of occurrence in peanut plantations at under 25 times.

Abstract

Precocious puberty also known as premature puberty is an abnormal pubertal development that can affect a child's growth and development. The clinical manifestations of precocious puberty are generally diverse and based on etiology are classified into central precocious puberty (GnRH dependent) and peripheral precocious puberty (GnRH independent). The main concern with precocious puberty is that precocious puberty can be a clinical symptom of an underlying serious disease such as a brain tumor, adrenal or gonadal tumor and others. Early identification of etiology plays an important role in prevention, diagnosis, and treatment of this disease. This literature review aims to determine the etiology and current management of precocious puberty. This literature review uses the keywords "Precocious Puberty AND etiology AND treatment" through the National Center for Biotechnology Information (NCBI) and Google Scholar databases. This article uses 11 articles that were used as references in its preparation. In conclusion, it is necessary to know the etiology of precocious puberty using imaging examinations for optimal management and excluding malignant abnormalities. The current treatment for central precocious puberty is GnRH agonists (gold-standard) and surgery in cases of intracranial lesions and peripheral precocious puberty using a combination of androgen antagonists (spironolactone) and aromatase inhibitors (anastrozole, testolactone) and surgery is indicated for gonadal and adrenal tumors. The role of parents is very important in early detection of precocious puberty, because the earlier the therapy, the better the prognosis.

Abstract

The area of mangrove ecosystems in West Nusa Tenggara Province continues to decline each year. One of the threatening factors that substantially contribute to such condition is socioeconomic activities of human beings in fulfilling their needs. An effort that can be made primarily to preserve the mangrove ecosystem is to quantify the economic value of environmental services provided by the mangrove ecosystem as a whole, so that the existence and sustainability of the mangrove ecosystem could be maintained. This research aims to calculate the total economic value of mangrove ecosystem services which indicate the four categories of ecosystem services including supporting services, provisioning services, regulatory services and cultural services. The research was carried out using a survey method by collecting data and information from location of this study to obtain actual data regarding the existence of the mangrove ecosystem. The results of the analysis show that the total economic value of mangrove ecosystem environmental services is 963,888,060/year. This value is divided into provider services (supply services) amounting to Rp. 153,002,250, regulatory services (arrangement services) Rp. 598,339,702, supporting services (support services) Rp. 2,243,250, and cultural services (cultural services) Rp. 210,308,857. The magnitude of the total economic value of mangrove ecosystem environmental services can be a reference for the government in determining compensation for services if there is degradation to mangrove ecosystem resources in the area.

Abstract

The addition of calcium, phosphorus and magnesium minerals has been carried out separately in vannamei shrimp cultivation activities using fresh water media. Furthermore, the combination of the three types of potassium is expected to mutually fulfill the mineral needs of vannamei shrimp so that their growth becomes more optimal. This research aims to analyze the growth of vannamei shrimp reared in various media with different mineral levels. The treatments in this study were P1 (30 ppt), P2 (20 ppt), P3 (10 ppt), P4 (0 ppt without the addition of minerals), and P5 (0 ppt with the addition of various types of mineral sources). The research results show that the best SGR weight is found in P1 at 12.42%/day. The highest SR value was also obtained at P1, namely 65%. The SR and SGR values at P5 are higher than at P4, but still lower than at P1, P2, and P3. Based on these results, it is known that the growth of vannamei shrimp reared in fresh water media with added minerals has increased compared to vannamei shrimp reared in fresh water media without added minerals, but is still lower compared to the growth of vannamei shrimp reared in water media. sea. Furthermore, research is needed on adding other types of minerals to low salinity vannamei shrimp cultivation media.
