Judul: Penentuan Tingkat Kemiskinan Menggunakan Logika Fuzzy pada Koperasi Baytul-Ikhtiar Bogor
Abstrak: Poverty is a problem for every country in the world, including Indonesia. Many indicators have been used to determining the level of poverty. Baytul-Ikhtiar cooperation (BAIK) is a cooperation that offers a micro-credit to the middle lower economy level. The cooperation has a problem to determine the level poverty of a person. The use of fuzzy logic system is one way to determine the level of poverty. One of model using the fuzzy logic is Mamdani model. There are some steps being taken in Mamdani model, namely fuzzification, evaluation, aggregation, and defuzzification. Inputs used in this paper are income, the number of dependent, the condition of building, and the consumption of rice. The output of this model is the level of poverty. It is compared to the output using data from the BAIK. It shows that the conformity percentage is 93,33 percent. It can be concluded that fuzzy model can be used to determine the level of poverty in BAIK cooperation.

Judul: Penentuan tingkat kemiskinan menggunakan logika fuzzy pada Koperasi Baytul-Ikhtiar Bogor
Abstrak: Kemiskinan merupakan masalah di setiap negara di dunia, termasuk di Indonesia. Banyak indikator yang digunakan untuk menentukan tingkat kemiskinan. Koperasi Baytul-Ikhtiar (BAIK) merupakan koperasi yang melayani kebutuhan mikro kredit pada masyarakat menengah ke bawah. Koperasi ini memiliki permasalahan untuk menentukan tingkat kemiskinan seseorang. Pemanfaatan sistem logika fuzzy merupakan cara yang tepat untuk menentukan tingkat kemiskinan sebuah keluarga, dalam hal ini digunakan model Mamdani. Ada beberapa tahapan yang dilakukan dalam model Mamdani, yaitu fuzzifikasi, evaluasi aturan-aturan, agregasi, serta defuzzifikasi. Masukan (input) yang digunakan dalam karya ilmiah ini adalah pendapatan keluarga, jumlah tanggungan, kondisi bangunan, dan konsumsi beras. Keluaran (output) dari sistem ini adalah tingkat kemiskinan. Output tersebut dibandingkan dengan data dari BAIK. Hasilnya menunjukkan bahwa persentase kecocokan dari sistem logika fuzzy adalah 93,33 persen. Hal ini menunjukkan bahwa model fuzzy dapat digunakan untuk menentukan tingkat kemiskinan pada Koperasi BAIK

Judul: Macroalgae development as feeding stimulants for the adult sea urchin (Tripneustes gratilla Linnaeus 1758)
Abstrak: Development of artificial feed for somatic growth and gonad quality is one of the focus of research on sea urchin aquaculture activities. Palatability is important factor when developing artificial feed for aquaculture diets. This study investigated the effects of macroalgae (Sargassum polycystum, Gracilaria lichenoides, and Ulva reticulata) as feeding stimulants to artificial diets consumption and gonad profile for the adult sea urchin Tripneustes gratilla, by three feeding trials. Previously starved T. gratilla were held in replicated (3X) 50 L aquaria with recirculation water system (in the first feeding trial) and flow through water system (in the second and third feeding trial). In the first feeding trial, preference of T. gratilla for dried macroalgae was assessed in choice feeding experiment. T. gratilla displayed significant preference for the agar containing dried U. reticulata at 20% agar weight over nine other diets treatment when they were offered simultaneously. Total protein, energy and the ratio of protein to energy in the dried macroalgae had no correlation on agar consumption by T. gratilla. Three artificial diets were made by incorporating one of each of these dried macroalgae at 5% feed weight used in the second feeding trial. Although no significant difference in artificial diets containing dried macroalgae, urchins fed diets containing dried macroalgae consumed more than basal diet when they were offered as single diet. These results indicate that dried macroalgae added to the artificial diets act as feeding stimulants and increasing the acceptability of artificial sea urchin diets. The third feeding trial used dried U. reticulata as feeding stimulant to artificial diet. Data suggest that artificial diet containing 10% dried U. reticulata boosting feed consumption and significantly increasing nutrient accumulation, gonad index, egg diameter and fix gonad color.
