Scylla serrata yang dikenal sebagai kepiting bakau merupakan sumber daya hayati ekosistem bakau yang hingga saat ini memiliki demand pasar yang cukup tinggi. Kondisi ini meningkatkan eksploitasi penangkapan species ini sehingga menyebabkan terganggunya populasi kepiting di alam. Penelitian ini bertujuan untuk mengetahui komposisi hasil tangkapan kepiting bakau (Scylla serrata) dengan melihat rasio kelimpahan dan hubungan lebar - berat kepiting bakau jantan dan betina dari hasil tangkapan di perairan Mangkang Wetan – Tugu, Kota Semarang, Jawa Tengah. Penelitian ini dilakukan pada musim penghujan di akhir tahun 2018 (Desember) dan awal tahun 2019 (Januari). Purposive sampling merupakan metode yang digunakan dalam penelitian ini dengan melakukan survey yang terarah dan terencana. Sampel kepiting bakau didapatkan dari hasil tangkapan nelayan yang diarahkan pada lima titik berdasarkan aktivitas yang berbeda. Hasil menunjukkan bahwa tangkapan kepiting bakau (Scylla serrata) pada Bulan Desember 2018 dan Januari 2019 di dominasi oleh kepiting jantan. Tangkapan bulan Desember 2018 memiliki rasio jantan : betina lebih besar (1,65:1) dari Januari 2019 (1,21:1). Korelasi lebar karapas dan berat kepiting bakau jantan dan betina bersifat allometrik, dimana jantan memiliki pola pertumbuhan allometrik positif sedangkan betina memiliki pola perumbuhan allometrik negatif. Dari data tersebut dapat disimpulkan bahwa populasi kepiting jantan lebih banyak ditemukan selama musim penghujan terutama di bulan Desember dan Januari. Ketidak seimbangan sex rasio ini akan menyebabkan terganggunya kestabilan populasi Scylla setrata di ekosistem estuaria Mangkang Wetan Semarang.  Scylla serrata known as mangrove crab as an edible food resources of the mangrove ecosystem which has a very high market demand. Due to this conditions will be affected in increasing exploitation of this species and cause inbalancing the population in the nature. The study aims to calculate abundance ratio and width – weight correlation between male and female of the crab caught from the estuary of Mangkang Wetan Semarang, Central Java. This study conducted at the end of 2018 (December) to the first month of 2019 (Januari). Survey method was used in this study by using purposive sampling in order to get the right data aimed as a planned. The crab sample was caught by some fisherman which were dirrected at five sampling points base on different fisherman activities. The results shows that the caught seasons in the rainy time  of Dec 2018 and Jan 2019, dominated by males crab (Scylla serrata). The December caught have higher sex ratio between male and female (1,65:1) compare to Januari caught (1,21:1). Correlation in carapage width and body weigth between the crabs male and female shows allometrik growth. Where, the male growth tend to have a positive allometric, while the female were negative. These can be conclude that, the male crabs were dominantly found during rainy seasons especially in December dan January. This imbalance of the sex ratio will disturb the population stability of Scylla setrata in estuary ecosystem of Mangkang Wetan Semarang.

Pennahia anea is among of the demersal fish landed at Asemdoyong Fish Auction Centre, Pemalang. P. anea doesn't show sexual dimorphism, so that other characters are needed to differentiate male and female individuals, i.e. truss morphometric and meristic characters. Previous studies have shown that truss morphometric and meristic can differentiate between male and female individuals. This study aims to describe the morphometric and meristic truss characters and determine the truss morphometrically and meristic characters that distinguish between males and females of Pennahia anea. The research used a survey method with a purposive random sampling technique. Male and female individuals of P. anea were examined based on their meristic and truss morphometric characters. The data were analyzed statistically using Mann Whitney non-parametric test. The result proved that male and female were significantly different in seven out of the 31 truss distances. Male individuals had a larger size than female individuals in three truss distances. In contrast, the male had a smaller size than the female individuals in four out of seven truss distances that distinguish both sexualities. The soft fin radius of the ventral fin was significantly different between male and female of P. anea. It could be concluded that male and female individuals of Pennahia anea have different truss distances and meristic characters with seven truss distances and one meristic character are different

The objectives of this research wereto analyze the local resource-based development of dairy cattle in orderto improve the production and quality of milk in Central Java. The research wascarried out by survey method. The research locations (Boyolali and Semarang) were chosen using purposive sampling method.In each regency was determined 2 sub district locations in which having the largest dairy cow population and 3 Dairy Cattle Farmer Associations (DCFA) in every sub district.Dairy farmers were sampled randomly, 10 farmers in every DCFA. Therefore, there were 120 dairy cattle farmers for sample. Data wereanalyzed using descriptive methods, location quotient (LQ) analysis and multiple linear regression statistical model. The dependent variables were yield and quality of milk (Y1,2) and the independent variables were human resources (x1), environmental resources (x2), capital resources (x3), entrepreneurship resources (x4), technology resources (x5), institution resources (x6) and infrastructure resources (x7). The LQ analysis showed that dairy cattle population, availability of forage and agricultural waste, and absorption of labour were very potential (LQ>1). Local resources significantly affected (P<0.01) the production and quality of dairy cattle milk. These results suggest that the development of dairy cattle business needs to consider the potential of local resources in order to improve the production and quality of milk.
