Shrimp Culture of Penaeus Monodon with Zero Water Exchange Model (Zwem) Using Molasses

One of the main obstacles to develop an intensive aquaculture is the accumulation of toxic inorganic nitrogenwhich should be kept very low by frequent water exchange or recycling of the water through a biofilter.This study describes another method of removing inorganic nitrogen using heterotrophic bacteria populationof which was augmented by the addition of a carbonaceous substance, molasses, to increase the feed C:Nratio under laboratory condition. The principal aim of study was to establish correlation C:N ratio levelwith levels of ammonia, nitrite, dissolved oxygen, pH and shrimp growth in Penaeus monodon shrimpculture with Zero Water Exchange Model (ZWEM) using molasses as carbon resource. It was found thataddition of molasses to shrimp farming with ZWEM had a role in removing ammonia and nitrite. Also,application of molasses to laboratory tanks increased the growth and percentage weight gain of shrimps andincreased the population of heterotrophic bacteria

A dynamic theory of parliamentary democracy

This paper presents a dynamic model of election, government formation, and legislation in a parliamentary democracy with proportional representation in which the policy chosen in one period becomes the status quo for the next period. The electorate votes strategically by taking into account the likely governments that parties would form and the policies they would choose as a function of the status quo. The status quo thus affects both the election outcomes and the bargaining power of the parties during government formation. A formateur party thus has incentives to strategically position the current policy to gain an advantage in both the next election and the subsequent bargaining over government formation and policy choice. These incentives can give rise to centrifugal forces that result in policies that are outside the Pareto set of the parties

Uji Efektivitas Ekstrak Biji Kakao (Theobroma Cacao L.) Sebagai Antibakteri Dalam Berbagai Konsentrasi pada Streptococcus Pyogenes

ABSTRAK Biji kakao adalah buah yang dikenal sejak dahulu sebagai buah yang memiliki peran penting dalam bidang kesehatan, salah satunya sebagai antibakteri. Biji kakao mengandung senyawa flavonoid, tanin, dan alkaloid yang memiliki efek antimikroba. Tujuan penelitian ini untuk mengetahui efektivitas ekstrak biji kakao terhadap bakteri Streptococcus pyogenes, yaitu dengan cara mengukur zona hambat menggunakan metode difusi Kirby-Beuer dengan konsentrasi ekstrak biji kakao 20%, 40%, 60%, 80% dan 100%. Hasil penelitian menunjukan ekstrak biji kakao dapat efektif memberikan efek antibakteri mulai dari konsentrasi terkecil 20% dengan rata-rata diameter zona hambat 8.07 mm sampai konsentrasi terbesar 100% dengan rata-rata diameter zona hambat 10.98 mm. Sedangkan rata-rata diameter zona hambat antibiotik Ampisilin sebagai kontrol (+) lebih besar dari konsentrasi ekstrak biji kakao. Berdasarkan data tersebut dapat disimpulkan ekstrak biji kakao dapat efektif menghambat pertumbuhan bakteri Streptococcus pyogenes  Kata kunci: Kirby-Bauer, Zona Hambat, Antimikroba ABSTRACT Cocoa Seed is a fruit that has been known for a long time as a fruit that has an important role in health, which is as an antibacterial. Cocoa seeds contain a high composition of flavonoids, tannins, and alkaloids which have antimicrobial effects. The aim of this research was to study the effect of cocoa seed extracts against Streptococcus pyogenes, by measuring the inhibition zone using the Kirby-Bauer diffusion method using concentrations of cocoa seed extract 20%, 40%, 60%, 80% and 100%. The results showed that chocolate seed extract could effectively provide an antibacterial effect ranging from a concentration of 20% with an average diameter of inhibition zone of 8.07 mm to the largest concentration of 100% with an average zone diameter of inhibition of 10.98 mm. While the average diameter of the inhibitory zone of antibiotic ampicillin as a control (+) is greater than the concentration of cocoa seed extract. Based on these data, it can be concluded that cocoa seed extract can effectively inhibit the growth of Streptococcus pyogenes. Keywords: Kirby-Bauer, Inhibitory zone, Antimicrobia
