Abstract

Ketersediaan kuantitas dan kualitas air bersih masih menjadi permasalahan baik di daerah perkotaan maupun pedesaan. Seperti di desa Menyali kecamatan Sawan kabupaten Buleleng provinsi Bali sumber air bersihnya memanfaatkan rembesan air sawah. Kualitas sumber air tersebut umumnya belum memenuhi syarat kualitas baku mutu air bersih. Untuk itu dibutuhkan teknolgi penyaring air yang sederhana, mudah dan murah. Salah satu alternative solusi potensialnya adalah penerapan teknologi saringan pasir lambat. Seperti yang telah diterapkan dalam program KKN-PPM di desa Menyali, media penyaring menggunakan media ganda yaitu pasir silica sebagai media penyaring dan karbon aktif sebagai penghilang warna dan bau. Aliran air melewati media penyaring dirancang dari bawah ke atas (up-flow), dan proses pencucian media penyaring secara gravitasi tanpa menggunakan pompa air dan blower. Penyaring air baku (kotor) menjadi air bersih yang dibuat menggunakan media penyangga ijuk, media penyaring pasir silica tebal 30 cm dan karbon aktif tebal 40 cm. Hasil pengujian menunjukkan bahwa air bersih hasil penyaringan telah memenuhi baku mutu air kelas I sesuai yang dipersyaratkan dalam Peraturan Gubernur Bali nomor 16 tahun 2016. Namun belum memenuhi baku mutu air minum, sehingga air bersih tersebut harus dimasak sampai mendidih terlebih dahulu jika akan diminum. Kata kunci : Penyaring air, air bersih, saringan pasir lambat, pasir silica, carbon aktif, upflow

Abstract

Penampakan minyak bekas hasil penggorengan yang berwarna coklat gelap tidak baik dikonsumsi akibat sifat fisik dan kimia minyak berubah sehingga dapat dimanfaatkan sebagai bahan bakar atau biodiesel. Tujuan penelitian ini adalah menganalisis bahan baku minyak hasil penggorengan setelah direfining dengan asam sulfat dan biodiesel hasil proses transesterifikasi dengan CaO sebagai katalis heterogen. Metode yang digunakan adalah spektroskopi Infra merah dan pengukuran secara mikroskopik. Hasil refining minyak bekas dengan asam sulfat lebih jernih dan analisis secara Infra Merah menunjukkan bahwa terjadi penurunan serapan pada berbagai bilangan gelombang dibandingkan terhadap minyak bekas. Serapan terjadi pada bilangan gelombang 2900 cm-1 diduga adanya ikatan –CH3, -CH2-, -C-H; 1656 cm1 diduga adalah ikatan C=C dan C=O; 1300 cm-1 diduga ikatan–C-H; dan 3600 cm-1 diduga adanya ikatan O-H. Secara mikroskopik menunjukkan hasil dengan ukuran partikel semakin kecil dan lebih homogen. The appearance of dark brown frying oil that is used for frying is not well consumed due to the changing physical and chemical properties of the oil so that it can be used as fuel or biodiesel. The aim of this study was to analyze the raw material of frying oil after being refined with sulfuric acid and biodiesel from the transesterification process with CaO as a heterogeneous catalyst. The method used is infrared spectroscopy and microscopic measurements.

Abstract

ABSTRAK: Arak merupakan salah satu minuman beralkohol khas Bali yang termasuk golongan C. Konsumsi berlebih dan terus menerus dapat mengakibatkan berbagai gangguan kesehatan sehingga penelitian tentang pengaruh kadar etanol dalam serum tikus wistar yang diberi asupan arak Bali perlu dilakukan. Tikus wistar dikelompokan menjadi 4 kelompok, masing-masing kelompok terdiri dari 6 ekor tikus. Kelompok kontrol tidak diberi asupan arak, kelompok I diberi asupan asupan arak 0,5 mL, kelompok II diberi 1,0 mL dan kelompok III diberi 2,0 mL, setiap hari selama 30 hari. Sampel darah diambil melalui plexus retroorbitalis, kemudian disentrifuse untuk mendapatkan serum untuk dianalisis kadar etanolnya. Kadar etanol dalam arak dan serum dianalisis dengan kromatografi gas detektor ionisasi nyala (GC-FID) tervalidasi. Validasi metode dilakukan dengan menentukan batas deteksi (LOD), batas kuantisasi (LOQ), persen koefisien variasi (% KV) dan %Recovery. Metode analisis ini sudah valid dengan LOD 0,0312 ppm, LOQ 0,1040 ppm, KV 0,85% dan %Recovery 99,77%. Lebih lanjut, peningkatan asupan arak menyebabkan peningkatan kadar etanol dalam serum tikus secara signifikan dengan p?0,05 dimana kadar tersebut sebesar 57,4667±0,70 mg/L, 79,8083±5,89 mg/L 133,4767±5,58mg/L masing-masing untuk kelompok I, II, dan III. ABSTRACT: Arak is one of the typical Balinese alcoholic beverages that belongs to group C. Continuous consumption of Balinese arak can cause various health problems, so research on the effect of ethanol levels in the serum of wistar rats fed with Balinese arak needs to be done. Wistar rats were devided into 4 groups where each group consisted of 6 rats. Control group 1 was not given alcohol intake, group I was given 0.5 mL of alcohol intake, group II was given 1.0 mL and group III was given 2.0 mL, every day for 30 days. Blood samples were taken through the retroorbital plexus, then centrifuged to obtain serum for analysis of the ethanol content. Ethanol levels in wine and serum were analyzed by validated flame ionization detector gas chromatography (GC-FID). Validation of the method is done by determining the limit of detection (LOD), limit of quantization (LOQ), percent coefficient of variation (% KV) and % recovery. This analytical method is valid with LOD 0.0312 ppm, LOQ 0.1040 ppm, KV 0.85% and %Recovery 99,77. Moreover, increasing the alcohol intake caused a significant increase in ethanol levels in rat serum with p?0.05 which the levels were 57.4667±0.70 mg/L, 79.8083 ±5.89 mg/L and 133.4767±5.58mg/L for group I, II, and III respectively.

Abstract

Suhu penyimpanan sangat mempengaruhi hasil analisis sampel metamfetamin menggunakan kromatografi gas dan spektroskopi massa. Optimasi suhu penyimpanan terhadap analisis metamfetamin serta metabolitnya dengan kromatografi gas dan spektroskopi massa telah dilakukan dengan tujuan untuk membandingkan hasil pembacaan dan kadar senyawa metamfetamin pada sampel urin yang berbeda. Sampel urin normal, sampel urin normal yang ditambahkan sabu-sabu, dan sampel urin pengguna masing-masing dikumpulkan sebanyak 60 mL. Hasil uji pendahuluan menunjukkan sampel urin normal negatif MA, sampel urin normal yang ditambahkan sabu-sabu dan sampel urin pengguna sabu-sabu positif MA, kemudian masing-masing sampel dibagi tiga kelompok untuk analisis langsung dan disimpan dalam suhu 4 dan 25oC selama 14 hari. Hasil analisis dengan kromatogarfi gas, pada kromatogram sampel urin normal tidak terdeteksi adanya serapan senyawa MA maupun metabolitnya hanya muncul serapan seperti 9-octadecenamide, hexadecanamide, dodecanamide, dan tetradecanamide yang merupakan puncak serapan dari lemak essensial. Sementara pada kromatogram sampel urin normal yang ditambahkan sabu-sabu dan sampel urin pengguna muncul puncak senyawa MA pada Rt 5,27-5,28 tetapi metabolit MA yaitu amfetamin hanya muncul pada kromatogram sampel urin pengguna yaitu pada Rt 5,07-5,08. Data hasil analisis kromatografi gas didukung oleh data pecahan m/z 44, 58, 91, dan 134 yang merupakan pecahan khas senyawa MA dan m/z 44, 65, 91, dan 120 yang menunjukkan pecahan khas amfetamin. Suhu 4oC merupakan suhu optimum dalam penyimpanan sampel urin pengguna sabu-sabu area tidak terjadi penurunan kadar MA yang signifikan. Kata kunci: Amfetamin, gas kromatografi, metamfetamin, sampel urin, spektroskopi massa. ABSTRACT The storage temperature of the methamphetamine samples has significantly influenced the analysis results of the samples using gas chromatography and mass spectroscopy. Optimization of the storage temperature for analysis of the methamphetamine and its metabolites by gas chromatography and mass spectroscopy has been done aiming to compare the level of methamphetamine compound in different urine samples. Normal urine samples, normal urine samples added with methamphetamine, and urine samples of the methamphetamine users were each collected as much as 60 mL. The result of the methamphetamine-screening test showed that the normal urine samples were negative but the normal urine samples added with methamphetamine and urine samples of the methamphetamine users were positive. Each sample was then divided into three groups for direct analysis and stored at 4 and 25 oC for 14 days. The methamphetamine analysis using gas chromatography showed that the chromatogram of the normal urine samples did not show any absorption of methamphetamine or its metabolites. Still, the absorption of 9-octadecenamide, hexadecanamide, dodecanamide, and tetradecanamide was detected, which were the absorption peaks of essential fats. Meanwhile, the chromatogram of the normal urine added with methamphetamine and the urine samples of the methamphetamine users indicated the peak of methamphetamine compound detected at Rt 5.27-5.28, however, the amphetamine (methamphetamine’s metabolite) peak was only detected at the chromatogram of the urine samples of the methamphetamine user, which was at Rt 5.07-5.08. The data of the gas chromatography analysis were supported by the fraction of m/z 44, 58, 91, dan 134 which were typical fractions of methamphetamine, and m/z 44, 65, 91, dan 120 were typical fractions of amphetamine. The results showed that the temperature of 4 oC was the optimum temperature for storing urine samples of methamphetamine users because there was no significant decrease in methamphetamine levels. Keywords: Amphetamine, gas chromatography, mass spectroscopy, methamphetamine, urine sample.
