Judul: Kemungkinan pembuatan ecohouse di Bogor
Abstrak: Ecohouse merupakan alternatif rumah ramah lingkungan yang mulai dikembangkan di belahan bumi ini. Bukan tempat tinggal biasa, tetapi bisa dimanfaatkan untuk hal yang lain seperti pemanasan air di siang hari dan pendingin ruang di malam hari, proses pemanasan dan pendingin yang terjadi semuannya memanfaatkan alam (matahari) dan lingkungan yang ada. Bahan pokok kayu dan bahan material yang lain mudah diperoleh di pasaran. Menurut Svenson (2002) prinsip dasar dan pengertian dari kampung ecohouse adalah bahwa semua benda dan lingkungannya saling berhubungan, maka segala tingkah laku kegiatan dan pola pikir manusia pada alam sekitar memberikan dampak pada lingkungan dan akan mempengaruhi keseimbangan dalam kehidupan Pemanasan dilakukan pada siang hari dan pendinginan dilakukan pada malam hari. Pemanasan ini yaitu untuk memanaskan air yang disirkulasikan ke atap sehingga mengalami peningkatan suhu, air yang panas ini dimanfaatkan untuk kegiatan sehari-hari seperti mandi, mencuci pakaian, buah-buahan, sayur- mayur dan kegiatan memasak lainnya. Sedangkan untuk pendinginan dimanfaatkan pada malam hari dengan proses pendinginan radiatif seperti yang dilakukan oleh Trisasisiwi (2000) dan Ronald (2002), pendinginan ini digunakan untuk ruangan dengan menghantarkan udara dingin dari lingkungan menggunakan koil-koil pendingin. Koil pendingin ini merupakan tempat untuk bersirkulasinya Pendekatan rancangan meliputi rancangan fungsional dan rancangan struktural. Rancangan fungsional berkaitan dengan fungsi atau peran tiap komponen penyusun sedangkan rancangan struktural meliputi ukuran, bentuk dan konstruksi komponen tiap bagian dan keseluruhan. ...

Judul: Analysis on Ecohouse’s space arrangement and airflow in rural area.
Abstrak: This paper explores the potential of temperature distribution using ventilation and natural convection in a Eco-house’s space arrangement and air flow in rural area by natural air cooling system for a construction designs as an illustrating Eco-House in Indonesia. The characteristics of the construction are analyzed in terms of heat and mass transfer and also air circulation by the Computational Fluid Dynamic method and practice. Based on the thermal comfort requirements of the Indonesian National Standard (SNI), the study has found that it is possible to use natural ventilation to create a thermally comfortable indoor environment in Eco-houses. This study also develops comprehensive design guidelines for natural ventilation at both the site planning and individual compartment house levels, using the specific materials. Finally by the simple geometry and calculation following the technical design temperature distribution in any point inside Eco-house will be predictable.

Judul: Mud Crab’s (Scylla serrata Forskal 1775) Response to Different Decaying Level of Gold Snail (Pomacea canaliculata Lamarck 1822) Bait.
Abstrak: Mud crab is well known as omnivorous-vigorous-voracious-opportunistic-scavenger. These intertidal animals applies mainly chemoreception in their predatory behaviour. It has been commonly assumed that non fresh gold snail bait is better than fresh bait in stimulating the mud crab. This research's aim is to analyze mud crab response to different decaying level of gold snail bait. Their response were observed as time required to touch the bait and pattern and direction of the mud crab in approaching the baits. The different decaying level of gold snail baits were shown on Total Volatile Base Nitrogen (TVBN) as 16.3 mg/100g (0 day); 534.1 mg/100g (3 days); and 887.4 mg/100g (6 days). The research was conducted from July 2009 until February 2011. The TVBN test for gold snail baits were conducted at Laboratory of BBPPHP Jakarta. The experiment was conducted in Pemalang. The result showed that the average period of mud crabs to touch the baits were 52.14 minutes; 61.57 minutes and 52.57 minutes. Anova test concluded no sufficient evidence of significant effect of TVBN content of gold snail bait on mud crab’s feeding behaviour. Movement pattern B, i.e. left and right deviation followed by straight forward movement to the bait, was commonly exhibited by the crabs. Consequences of time period required by the mud crab to approach the bait on fishing operation is discussed.
