ABSTRAK Kabupaten Wonogiri merupakan salah satu daerah yang terdapat penangkapan Lobster. Lobster batu (Panulirus penicillatus) merupakan jenis yang paling sering dominan tertangkap oleh krendet dan jaring hampar. Informasi tentang sebaran ukuran lobster yang tertangkap sangatlah diperlukan. Hal ini dilakukan guna memperoleh gambaran tentang pertumbuhan lobster serta mengetahui persamaan regresinya sebagai dasar pengelolaan lobster batu. Data diambil setiap satu bulan sekali selama enam bulan, pada periode Oktober 2013–Maret 2014 dan dianalisis dengan menggunakan analisis regresi linear sederhana. Hasil ukuran pertama kali tertangkap (L50%=56mm) kurang dari setengah panjang asimtotik (½ L∞=67mm). Hubungan panjang-berat lobster jantan yaitu W= 0,003L 2,68 dan lobster betina W= 0,0041L 2,59. Faktor kondisi pada lobster jantan (1,17) dan betina (1,10). Persamaan pertumbuhan Von Bertalanffy lobster jantan Lt = 136 (1-e-0,15(t+0,89)) dan lobster betina Lt = 123(1-e-0,19(t+0,65)), hal ini menunjukkan bahwa lobster jantan tumbuh lebih cepat dari lobster betina.

Information on size composition of lobster is very important. This was done to obtain an overview of lobster’s growth and linear regression. Data taken every month for six months, on October until March and processed with a simple linear regression. The result of first size of caught (L50%=56mm) is lower than the half of asymptotic length (½ L∞=67mm). Length-weight relationship of male lobster is W = 0,003L2,68 and female lobster is W = 0,0041L2,59. The condition factor of male (1,17) and female (1,10) lobster has equal of plupmness. Von Bertalanffy equation for male lobster is Lt= 136(1-e-0,15(t+0,89)) and female lobster is Lt=123(1-e-0,19(t+0,65)), so it can be stated the male lobster growing faster than female lobster.

The land use intensity is an aspect that needs to be regulated related to urban development. This study aims to develop the concept of developing land use intensity in a commercial area in the Muntilan district so that it can be arranged to accommodate various activities through sustainable land use. The research method uses a quantitative approach with analysis of the intensity of land use at the study locus. The results show that the BCR and FAR values in the area are still below the maximum value and the Open Space Ratio value has not exceeded the calculated minimum value. The calculation of the existing building demarcation analysis still has not exceeded the calculated provisions so that development can still be carried out horizontally and vertically. The result of development concept is an Eco-Commercial Area by considering the intensity of land use. Keywords: land use intensity; trade area; city Intensitas Pemanfaatan Lahan merupakan aspek yang perlu diatur dalam hubungannya dengan perkembangan kota. Penelitian ini bertujuan untuk menyusun konsep pengembangan intensitas pemanfaatan lahan pada kawasan perdagangan di Kecamatan Muntilan agar dapat diatur untuk mewadahi berbagai aktivitas melalui pemanfaatan lahan secara berkelanjutan. Metode penelitian menggunakan pendekatan kuantitatif dengan analisis Intensitas Pemanfaatan Lahan pada lokus studi. Hasil penelitian menunjukkan bahwa nilai KDB dan KLB kawasan masih di bawah nilai maksimal dan nilai KDH belum melampaui nilai minimum yang telah diperhitungkan. Perhitungan analisis GSB dan GSJ secara eksisting masih belum melampaui ketentuan yang telah diperhitungkan sehingga pembangunan masih dapat dilakukan secara horizontal maupun vertikal. Konsep pengembangan yang dihasilkan adalah Eco-Commercial Area dengan mempertimbangkan intensitas pemanfaatan lahannya. Kata Kunci: intensitas pemanfaatan lahan; kawasan perdagangan; kota
