ABSTRAK
Jamur Tiram (Pleurotus Ostreatus) adalah tanaman sejenis fungi yang sering dibudidayakan pada lingkup pertanian Indonesia, dikarenakan tanaman ini memiliki banyak kegunaan dari segi kuliner dan kesehatan.. Jamur tersebut dibesarkan dengan cara memanipulasi parameter lingkungan, agar sedemikian rupa sehingga dapat tumbuh didalam suatu wadah/tempat yang telah disediakan.. Perlu diketahui bahwa jamur tersebut pertumbuhannya dapat dipengaruhi oleh pH, suhu dan kelembapan yang dapat mempengaruhi tumbuhnya jamur, agar pertumbuhan budidaya jamur tersebut dapat terpantau dan terkontrol, maka diperlukan sebuah alat yang dapat mengontrol parameter lingkungan tersebut agar sesuai dengan yang seharusnya..

ABSTRACT
Oyster Mushroom (Pleurotus Ostreatus) is a type of fungus that is often cultivated in the Indonesian agricultural sphere, because this plant has many uses in terms of culinary and health. . Mushrooms are raised by manipulating environmental parameters, so that they can grow in a container / place that has been provided.. It should be noted that the growth of the fungus can be influenced by pH, temperature and humidity which can affect the growth of fungi, so that the growth of mushroom cultivation can be monitored and controlled, so a tool that can control the parameters of the environment is needed to match what it should be.

Survivabilitas Rayap Nasutitermes dan Macrotermes (Isoptera : Termitidae) Terhadap Perlakuan Kadar Karbon Dioksida Bervariasi
No full textABSTRAK
Penelitian ini bertujuan untuk mengetahui apakah terdapat
pengaruh karbon dioksida bervariasi terhadap survivabilitas rayap
Nasutitermes dan Macrotermes (Isoptera : Termitidae). Metode
pengumpulan sampel yang digunakan adalah teknik Direct Sampling
(pengambilan langsung). Jumlah sampel yang digunakan yaitu 50
rayap Nasutitermes dan 50 rayap Macrotermes. Penelitian ini
menggunakan kadar karbon dioksida bervariasi mulai dari 500 ppm,
1000 ppm, 1500 ppm dan 2000 ppm dengan menggunakan tiga kali
pengulangan selama satu jam. Jenis penelitian ini merupakan
penelitian Kuantitatif yang dianalisis lebih lanjut menggunakan
(ANOVA). Hasil penelitian menunjukkan bahwa karbon dioksida
bervariasi berpengaruh terhadap kemampuan Survivabilitas rayap
Nasutitermes dan Macrotermes. Secara umum, pada rayap
Nasutitermes semakin tinggi kadar karbon dioksida, semakin rendah
juga persentase rayap yang bertahan hidup. Titik optimum terjadi
pada kadar karbondioksida 500 ppm, dimana seluruh rayap bertahan
hidup. Kadar karbon dioksida yang tinggi sebesar 2000 ppm dapat
mengurangi kelangsungan hidup rayap. Sama halnya dengan
kemampuan hidup rayap Macrotermes, pada grafik Macrotermes
menunjukkan pola yang jelas, semakin tinggi kadar karbondioksida,
semakin rendah juga persentase rayap yang bertahan hidup. Jadi dapat
disimpulkan bahwa kadar karbon dioksida bervariasi berpengaruh
terhadap Survivabilitas rayap.

ABSTRACT
This research aims to determine the effect of varying
concentration of carbon dioxide on the survivability of Nasutitermes
and Macrotermes termites (Isoptera: Termitidae). The sample
collection method used was the Direct Sampling technique. The
sample size consisted of 50 Nasutitermes termites and 50
Macrotermes termites. The study employed varying carbon dioxide
levels of 500 ppm, 1000 ppm, 1500 ppm, and 2000 ppm, with three
repetitions over one hour. This research is quantitative and was
further analyzed using ANOVA. The results indicate that varying
levels of carbon dioxide influence the survivability of Nasutitermes
and Macrotermes termites. In general, for Nasutitermes termites, the
higher the carbon dioxide level, the lower the survival percentage.
The optimum point was at 500 ppm, where all termites survived. High
carbon dioxide levels of 2000 ppm reduced the survival rate of the
termites. Similarly, the survival pattern for Macrotermes termites
showed that the higher the carbon dioxide level, the lower the survival
percentage. Therefore, it can be concluded that varying levels of
carbon dioxide affect termite survivability.

Survival Responses of Two Termite Genera to Environmental Stressors as Bioindicators of Climate Change
No full textTermites are sensitive to environmental fluctuations and hold potential as bioindicators of climate change. This study evaluated the survivability of Nasutitermes and Macrotermes under controlled variations in temperature, relative humidity (RH), and CO₂ concentration. Laboratory experiments were conducted using eleven temperature levels (0–50°C), seven RH levels (40–100%), and four CO₂ concentrations (500–2000 ppm). Each treatment was replicated three times with 50 worker termites per replicate. Survivability, measured as percent survival after one hour of exposure, was analyzed by one-way ANOVA followed by Tukey’s HSD test (p < 0.05). The results indicated that both genera exhibited sharp declines in survival under temperature extremes and elevated CO₂. Optimal survivability for Nasutitermes and Macrotermes occurred at moderate temperatures (25–35°C), relative humidity (60–80%), and ambient CO₂ levels (500 ppm), while extreme conditions significantly increased mortality. The study highlights species-specific tolerance thresholds and confirms that environmental stressors directly affect termite physiology and behavior. These results confirm termites’ potential as reliable bioindicators, providing a practical tool for monitoring ecosystem responses to climate stress and informing strategies for sustainable ecosystem management
