Synthesis of Zeolite-NaY for Methane Adsorption

This research aims to synthesize zeolite-NaY material which is then applied as an adsorbent for methane adsorption. Zeolite-NaY was synthesized by hydrothermal method and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), and isotherm adsorption-desorption N2 (BET). The characterization results showed that synthesized zeolite-NaY had a diffraction peak with the highest intensity at 2θ = 6° and its morphology showed octahedral crystals. Zeolite-NaY was then applied as an adsorbent for methane adsorption. The methane adsorption test on zeolite-NaY was carried out using the gravimetric method at temperature of 30 °C and pressure of 1 bar. The data was recorded of increasing time every 1 minute until constant. The adsorption test results showed that the methane adsorption capacity on the zeolite-NaY material was 0.436 % wt

Resistensi Lalat Rumah, Musca Domestica Linnaeus (Diptera: Muscidae) Dari Empat Kota Di Indonesia Terhadap Permetrin Dan Propoksur

House flies (Musca domestica Linnaeus) is one of the common urban pests causing health, economics, and aesthetics problems. Although intensive control by using inseticides are carried out, there are reports of control failures, which are probably due to insect resistance. Bioassay tests with topical application to study the status as well as resistance mechanism of house flies collected from the city of Jakarta (JKT), Bandung (BDG), Yogyakarta (YGY) and Surabaya (SBY) to pyrethroid (permethrin) and carbamate (propoxur) insecticides were carried out. The results show that, as compared to the most susceptible strain (YGY), we found that BDG strain is highly resistant to permethrin with resistance ratio (RR) of 133.7 fold. SBY strain was the most resistant to propoxur with RR of 38.36 fold, followed by Bandung strain with RR of 18.22 fold. The addition of piperonyl butoxide (PBO) to either permethrin or propoxur in most of the strains caused a decrease in LD50 values and increasing the synergist ratio (SR) suggesting that the detoxifying enzyme mixed function oxidase (MFO) played an important role in the development of resistance to permethrin and propoxur. Our study is the first report of M. domestica resistance to permethrin and propoxur in Indonesia

KADAR SENYAWA TOKSIK DALAM DARAH IKAN NILA (Oreochromis niloticus) SAAT MUSIM UP-WELLING DI DANAU MANINJAU, SUMATRA BARAT

Maninjau lake is the largest center for the freshwater floating-net-cage fisheries system in West Sumatra. Every year, during the up-welling season, a huge number of fish suffered to death in the lake including nile tilapia (Oreochromis niloticus), a common species cultivated in the floating-net cages. This current study aimed to determine the factors contributing to the death of fish by measuring the concentration of toxic chemical substances in the blood plasm of nile tilapia as well as in the subtrate collected from the bottom of the lake. The samples were collected in the sites with higher number of floating-net cages as well as higher number of mass death of fish (Tanjung Sani, Pakan Raba’a dan Maninjau) during the up-welling season. The result revealed that the levels of phosphate, nitrate, nitrit, and amonium were higher in the blood plasm of the fish. Moreover, the levels of those chemical substances were also higher in the substrate of the lake. The higher concentration of the toxic chemical substances might contribute to the mass death of fish living in the floating-net cages during the up-welling season

PENGARUH TEMPAT TUMBUH TERHADAP KADAR LOGAM BERAT TIMBAL (Pb), CADMIUM (Cd) dan TEMBAGA (Cu) EKSTRAK RIMPANG JAHE EMPRIT (Zingiber officinale Var. amarum) DENGAN METODE SPEKTROFOTOMETRI SERAPAN ATOM

Rimpang jahe emprit (Zingiber officinale Var. amarum) merupakan bahan baku obat tradisional yang memiliki frekuensi penggunaan dengan persentasi 9,65% terbesar dibanding rempah lainnya. Rimpang jahe emprit digunakan dalam formulasi obat baik dalam bentuk segar maupun instan sebagai antiseptik, ekspektoran, spasmolitik dan antiasma karena jahe emprit mengandung senyawa monoterpenoid dan minyak atsiri sebesar 3,5%. Lokasi tempat tumbuh memberikan peran besarnya cemaran yang terdapat dalam rimpang jahe emprit (Zingiber officinale Var. amarum). Cemaran logam berat merupakan persyaratan mutu yang perlu diperhatikan dalam pembuatan obat tradisional salah satu logam yang mencemari rimpang yaitu logam timbal (Pb), Cadmium (Cd) dan Tembaga (Cu). Tujuan penelitian ini untuk mengetahui pengaruh tempat tumbuh terhadap perbedaan kadar logam berat Timbal (Pb) ekstrak rimpang jahe emprit dengan metode Spektrofotometri Serapan Atom (SSA). Jenis penelitian yang digunakan adalah penelitian eksploratif, dengan variable bebas adalah tempat tumbuh dan variable terikat adalah kadar logam Pb, Cd dan Cu. Analisa data diolah menggunakan uji Anova untuk mengetahui pengaruh tempat tumbuh terhadap kadar logam Pb, Cd dan Cu. Hasil menunjukkan bahwa tempat tumbuh berpengaruh terhadap kadar logam berat Cd dan Cu dengan nilai (p0,05) pada ekstrak rimpang jahe emprit (Zingiber officinale Var. amarum) Kata kunci: jahe emprit, logam Cd, logam Cu, logam Cd, tempat tumbuh Abstract Emprit ginger rhizome (Zingiber officinale Var. amarum) is a raw material for traditional medicine which has a frequency of use with the largest percentage of 9.65% compared to other spices. Emprit ginger rhizome is used in medicinal formulations both in fresh and instant form as antiseptic, expectorant, spasmolytic and anti-asthmatic because emprit ginger contains monoterpenoid compounds and 3.5% essential oils. The location where it grows gives a big role in the contamination contained in the rhizome of ginger emprit (Zingiber officinale Var. amarum). Heavy metal contamination is a quality requirement that needs to be considered in the manufacture of traditional medicine. One of the metals that contaminate the rhizome is lead (Pb), Cadmium (Cd) and Copper (Cu). The purpose of this study was to determine the effect of growing sites on differences in heavy metal levels of Lead (Pb) extract of emprit ginger rhizome using Atomic Absorption Spectrophotometry (AAS). The type of research used is exploratory research, with the independent variable is the place of growth and the dependent variable is the metal content of Pb, Cd and Cu. Analysis of the data was processed using the Anova test to determine the effect of the growing place on the metal content of Pb, Cd and Cu. The results showed that the place of growth affected the levels of heavy metals Cd and Cu with a value of (p0.05) in the extract of emprit ginger rhizome (Zingiber officinale Var. amarum).
