Tujuan dari penelitian ini adalah untuk mengetahui dampak temperature dan pH pada polulasi Pseudomonas pendegradasi limbah LAS. Hasil penelitian menunjukkan bahwa isolate bakteri P2.1 dapat tumbuh maksimal pada pH 8; isolate P3.2 dan C2.1 dapat tumbuh optimal pada pH 7, sedangkan isolate C2.2 dan C2.3 dapat tumbuh optimal pada pH 5, dan isolate P3.2 dapat tumbuh optimal pada suhu 40oC, isolate C2.1 C2.2 dan C.2.3 dapat tumbuh optimal pada temperature 30oC. Pada penelitian ini juga terdapat isolate yang tidak terpengaruh oleh perlakuan suhu. Hal ini dimungkinkan karena variasi suhu yang digunakan masih kisaran suhu optimum untuk pertumbuhan isolate, sedangkan isolate lain menunjukkan respon pertumbuhan akibat perlakuan suhu. Beberapa isolate menunjukkan pertumbuhan yang lambat, hal ini karena suhu yang digunakan untuk perlakuan dibawah suhu minimum atau diatas suhu maksimum untuk pertumbuhan bakteri. Kata kunci: Pseudomonas, LAS, temperatur

The adhesion of green mussel spit is highly correlated with depth. This study aims to establish the correlation between the depth and duration of observation with the abundance of green mussel spat (Perna viridis) in the coastal waters of Waiheru Village, located in Inner Ambon Bay. This study was undertaken utilising three floating net cages (KJA) possessed by local fishermen. The KJA utilised in this investigation had dimensions of 2.0 x 2.5 metres. Each KJA is equipped with 4 threads of hanger rope, resulting in a total of 12 hangers. Each rope hanger is positioned at specific depths, specifically at depths of 3, 6, and 9 metres. The net is 40 cm by 40 cm. Observations were conducted on days 2, 4, 6, 8, 10, 12, and 14 after the nets were strung. The findings indicated that the depth and duration of observation significantly influenced the quantity of green mussel spat. Specifically, more spat was observed compared to other days, suggesting a stronger attachment at that depth and observation period. Nevertheless, on the 10th day of observation, there was a surge in the quantity of green mussel spit.

Most people, especially in rural areas, do not know the dangers of used cooking oil for health when reused. Used cooking oil that is no longer used should not be thrown into the environment because it can cause environmental pollution (soil and water). Used cooking oil can be processed into biodiesel as an alternative fuel, so it can be a source of additional income. This Community Service (PkM) activity aims to provide education about the dangers of used cooking oil for human health and the environment, as well as practice how to process used cooking oil into biodiesel for the women of the Al-Hijrah Ta'lim Assembly, Air Ali Hamlet, Negeri Rumah Tiga, Ambon. . The methods used in this PkM activity are lecture, demonstration and practice methods. All participants were very enthusiastic about participating in this PkM activity until the end. After following the education delivered by the lecturers, all participants became aware and aware of the dangers of used cooking oil for health and the environment. The participants were also very happy because they gained knowledge about how to process used cooking oil into biodiesel. This PkM activity has had a very positive impact on the surrounding community in Air Ali Hamlet.

Rumput kebar merupakan tanaman yang mengandung senyawa aktif seperti flavonoid, vitamin A, dan vitamin E yang diduga mampu mengatasi dampak buruk radikal bebas berupa asap rokok. Tujuan dari penelitian ini adalah untuk mengetahui efek pemberian ekstrak etanol rumput kebar (Biophytum petersianum K.) terhadap jumlah embrio dan anak tikus Rattus norvegicusyang terpapar asap rokok. Penelitian mengggunakan metode eksperimental laboratorik dengan rancangan acak lengkap (RAL) yang terdiri dari empat perlakuan yang masing-masing diulang tiga kali, yaitu (-): Kelompok kontrol negatif yaitu tikus yang tidak diberi perlakuan, (+): Kelompok kontrol positif yaitu tikus dipaparkan asap rokok selama 28 hari, (0.067): Kelompok tikus yang dipapar asap rokok selama 28 hari kemudian diberi ekstrak etanol rumput kebar dosis 0.067mg/ekor/hari selama 28 hari, dan (0.135): Kelompok tikus yang dipapar asap rokok selama 28 hari kemudian diberi ekstra ketanol rumput kebar dosis 0.135mg/ekor/hari selama 28 hari. Setelah perlakuan asap rokok dan pemberian ekstrak etanil rumput kebar, tikus dikawinkan. Pengamatan jumlah embrio dilakukan pada saat masa kebuntingan ke 12 hari kemudian dibedah, sedangkan pengamatan jumlah anak dilakukan pada saat anak tikus dilahirkan. Data yang diperoleh dianalisis dengan Analysis of Variance (ANOVA)-SPSS versi 16.0 dilanjutkan dengan uji Duncan dengan selang kepercayaan 95% (Î± = 0.05). Hasil penelitian menunjukan bahwa pemberian ekstrak etanol rumput kebar dengan dosis 0.135mg/ekor/hari mampu menjaga keberhasilan implantasi embrio ke dinding uterus sehingga rata-rata jumlah embrio dan anak tikus meningkat.

This study aims to determine the relationship between the physical and chemical factors of the waters (Temperature, Salinity, pH, Dissolved Oxygen) and the diversity of sea cucumbers (holothuroidae) in the coastal waters of Pia Hamlet. The method used is the Belt Transect method. Analysis of diversity data using the Shannon-Winner diversity index formula then to determine the functional relationship between sea cucumber diversity and physical and chemical factors of waters was carried out using simple linear regression and multiple linear regression. The results showed that 1 class, 2 orders, 2 families, 3 genera with 5 species, namely Holothuria atra, Holothuria leucopsilota, Holothuria scabra, Bohadschia argus and Synapta maculate. The diversity index value is low with an average value of 0.7214. The temperature measurement results ranged from 28.04°C-30.16°C. Salinity measurement results ranged from 31.21-32.26 ‰. The results of pH measurements ranged from 6.80-7.41. Dissolved oxygen measurement results ranged from 5.96-6.40 mg/L. The results of simple regression analysis showed that dissolved oxygen had a relationship and had a significant effect on sea cucumber diversity. The results of multiple regression analysis explained that salinity and dissolved oxygen, if tested together, had a strong relationship and had a significant effect on sea cucumber diversity.
