Kabupaten Cilacap merupakan salah satu kabupaten yang memilki potensi yang tinggi di bidang perikanan tangkap karena terletak di pesisir pantai selatan Pulau Jawa dimana terdapat pangkalan perikanan yang terbesar. Pemanfaatan udang P.coromandelica yang terus meningkat, menyebabkan tingginya intensitas penangkapan dan menurunnya daya dukung lingkungan perairan Kab. Cilacap, hal ini memungkinkan perkembangan stok dari jenis udang ini terhambat. Tujuan dari penelitian ini adalah untuk mengetahui aspek biologi, status pemanfaatan dan konsep pengelolaan udang P. coromandalica di perairan Cilacap. Metode penelitian yang digunakan adalah metode survey, dengan teknik pengambilan sampel secara simple random sampling yaitu mengambil sampel udang sekitar 10% dari total hasil tangkapan salah satu alat tangkap jaring arad pada setiap TPI. Jenis data yang digunakan yaitu data primer dan data sekunder. Penelitian ini dilakukan pada bulan September – Desember 2012. Hasil penelitian menunjukkan bahwa Pertumbuhan udang P.coromandelica jantan dan betina memiliki nilai b 1,657 dan 2,22 ini menunjukan bahwa pertumbuhan udang bersifat allometrik negative. Sebagian besar udang P.coromandelica belum matang gonad dan belum siap memijah. faktor kondisi untuk udang P.coromandelica jantan dan betina menunjukkan 1,054 dan 1,117 bahwa tubuh udang kurus. Nisbah kelamin jantan dan betina adalah 1 : 1,545 artinya bahwa perairan Kab. Cilacap tersebut masih normal. Nilai Lm 41 mm, Lc50% 37 mm dan nilai L∞ jantan dan betina adalah 53,68 mm dan 64,21mm.

ABSTRACT  Background Menopause is a phase of female reproduction characterized by the cessation of menstruation due to decreased production of the hormone estrogen, which begins to occur in the age range of 40-50 years. World Health Organization (WHO) Projection (2014) in 2030 the number of women worldwide entering menopause is estimated at 1.2 billion people, while in 2025 there are an estimated 60 million menopausal women. In 2016, in Indonesia there were 14 million (7.4%) menopausal women and the population of Central Java province in the group of women aged 40-44 years was 1,240,110 million (7.2%), aged 45-49 years was 1,215 .340 million (7.1%) and ages 50-54 totaling 1,126,818 million (6.7%) (Ministry of Health, 2016; BPS Central Java 2016). Signs of menopausal symptoms vary for each woman such as hot flashes, depression, anxiety, and mood instability. One of the needs of menopausal women to overcome the discomfort due to changes that occur by consuming nutrients that contain carbohydrates, proteins, fats, vitamins, minerals and phytoestrogens (Andira, 2010; Melani, 2012).  Purpose to know the respondent's characteristic relationship to the fulfillment of phytoestrogen requirement in menopausal women. Method The type of research used was an analytical survey with a population of 671 people in the menopause age group (ages 45 - 59 years) in Ngembak Village. Samples were taken using a simple random sampling technique of 47 people. The study was conducted from January to December 2019 using primary data from the Food Frequency Form (FFQ) which contained various foods containing phytoestrogens as well as secondary data whose results were analyzed using the Lambda Contingency Coefficient formula. Result Based on the results of research and data analysis, it is known that the variable that has a relationship with the fulfillment of phytoestrogens is the Body Mass Index (BMI) variable. This is indicated by the p-value of 0.458 <0.05. Conclusion Body Mass Index (BMI) is a measure used to assess a person's nutritional status, so that the nutritional needs needed by someone including menopausal women can be identified from the calculation of BMI.

Statistics has been a compulsory subject in many study programs, considering its importance as a provision for university students to conduct research, which is one of the requirements for graduation. However, statistics anxiety, which hurts statistical competence, is a common phenomenon in students. This study, first, aims to describe students' statistics anxiety. It also wants to examine whether gender differences are also a cause of this statistics anxiety. The study took 167 samples of students at a university in Central Java, Indonesia. They were selected by simple random sampling. The statistics anxiety scale has been tested for its validity and reliability and becomes the instrument in this study. This study found that the majority of students' statistics anxiety was on average at a moderate level. It also found no difference in statistics anxiety based on gender, seen either as a whole or in terms of each domain. Further related research is expected to examine statistics anxiety with a qualitative approach or mixed methods to describe its nature and causes in more depth, as well as efforts that can be made to reduce such anxiety. Keywords: statistics anxiety, gender, interpretation
