Telah dilakukan penelitian mengenai efek antikandida in vitro dengan menggunakan ekstrak segar bawang putih baik jenis jantan umbi tunggal maupun jenis betina (umbi bergerombol). Bawang putih diperoleh secara acak dari beberapa pasar dan pasar swalayan. Pembuktian dilakukan dengan menggunakan metoda tabung pengenceran dan metode difusi "disc agar" untuk menetapkan kadar hambat minimal (Minimal Inhibitory Concentration = MIC) dan kadar bunuh minimal (Minimal Lethal Concentration = MLC ). Dengan metoda tabung pengenceran, MIC dan MLC bawang jantan pada inkubasi 370 C selama 24 jam berturut-turut adalah 0,98 mg/mL dan 3,91 mg/mL, sedangkan bawang putih betina : 0,245 mg/mL dan 31,25 mg/mL. Dengan metoda difusi "disc agar" hanya ditentukan MIC dengan adanya zona hambatan di sekitar kertas cakram (diameter 8 mm). Zona hambatan kedua jenis bawang mulai tampak jelas pada kadar 31,25 mg/mL sebesar 13,7 mm (bawang jantan) dan 12,6 mm (bawang betina). Secara statistik hasil tersebut tidak dapat dibandingkan dengan flukonazol sebagai kontrol. ...... Anticandidal effect study of freshly garlic extract both male type and female type of garlic has been carried out in vitro. The garlic was taken randomly from market and supermarket. By using the tube dilution method and the diffusion disc-agar method to asses Minimal Inhibitory Concentration (MIC) and Minimal Lethal Concentration ( MLC ). With tube dilution method, MIC and MLC of the male type of garlic extract is 0.98 mg/mL and 3.91 mg/mL respectively, while the female type of garlic extract is 0.245 mg/mL and 31.25 mg/mL respectively ( on 24 hour incubation at 370 C ). By using diffusion disc-agar method, the extract of garlic both male and female type of garlic as well has just shown inhibition zone around the paper disc ( 8 mm in diameter ) at 31.25 mg/mL concentration. The inhibition zone diameters are 13.7 mm for male type and 12.6 mm for female type of garlic. Statistically it is not possible to compare this result with fluconazole as a control drug.

Impor bawang putih telah dilakukan oleh pemerintah Indonesia pada tahun 2011-2020 karena produksi dalam negeri hanya mencukupi sekitar tiga hingga lima persen dari kebutuhan masyarakat. Adanya tambahan pasokan bawang putih impor pada pasar dalam negeri akibat kebijakan impor tersebut diduga akan menurunkan harga eceran bawang putih. Penelitian ini bertujuan menguji pengaruh volume impor bawang putih terhadap harga eceran bawang putih di Indonesia. Dengan menggunakan metode Distributed Lag Model (DL-Model) dan Vector Error Correction Model (VECM) serta data bulanan periode Januari 2011-Desember 2020, penelitian ini menunjukkan bahwa pengaruh volume impor bawang putih mulai dapat menurunkan harga eceran bawang putih setelah satu bulan pelaksanaan impor. Pengaruhnya terus signifikan hingga 6 bulan pasca pelaksanaan impor. Hasil ini menunjukkan bahwa dalam jangka waktu satu bulan (jangka pendek), kebijakan melakukan impor bawang putih belum mampu mempengaruhi harga eceran bawang putih. Namun dalam jangka panjang (setelah satu bulan hingga 6 bulan), kebijakan melakukan impor bawang putih signifikan mempengaruhi penurunan harga eceran bawang putih. ......Garlic import has been carried out by Indonesian government in 2011-2020 because domestic production is only sufficient for about three to five percent of people’s needs. The addition supply of imported garlic in domestic market due to the import policy is expected to reduce garlic retail price. This study aims to examine the effect of garlic import volume on garlic retail price in Indonesia. By using Distributed Lag Model (DL-Model) and Vector Error Correction Model (VECM) with monthly data for Januari 2011 – December 2020, this study shows that the effect of garlic imports volume begins to reduce the retail price of garlic after one month of import implementation. The effect continues to be significant up to 6 months after the import implementation. These results indicate, within a period of one month (short term), the policy of importing garlic has not been able to affect the retail price of garlic. However, in the long term (after one month to 6 months), the policy of importing garlic significantly affects the decline in retail prices of garlic.

Latar belakang: Aged garlic exlraci adalah bawang putih yang telah direndam didalam ethanol 15-20% selama 20 bulan pada suhu kamar sehingga zat aktif didalam bawang putih mentah berubah menjadi komponen sulfiu' yang mudah larut dalam air, yaitu S-allylcysteine (SAC), dan S-allylmercaptocysteine Aged garlic extract dapat meningkatkan produksi nitric oxide, karena S-ajlilcysteine dapat memicu masuknya kalsium kedalam sel endotel, selanjutnya merangsang endoiheliol nitric oxide .synihase memproduksi nitric oxide. Nitric oxide yang telah dibcntuk akan segera berdiiiisi kedalam sel otot polos yang berdekatan serta mengalctifkan beberapa mekanisme yang akan menyebabkan otot polos relaksasi dan tonus pembuluh darah menurun. Cold Pressor Test adalah suatu standar tes untuk memprediksi orang yang normotensi kelak akan mengidap hipenensi jika hasil tesnya masuk kedalam kategori hiper-reaktor, karena orang hiper-reaktor teljadi hipersesitivitas pada sistem saraf simpatisnya dan gangguan pada pembentukan nitirc oxide sebagai vasodilator di pembuluh darah. Bila aged garlic extract dapat meningkatkan kadar nitric oxide maka tonus pcmbuluh darah pada orang hiper-realctor dapat dijaga agar tidak meningkat ketika teriadi vasokonstfiksi. Tujuan: Mengetahui efek aged garlic extract pada proses peningkatan kadar nitric oxide dalam darah subyek laki-laki hiper realctor usia 20-30 tahun Metode: Mendapatkan sampcl hiper-realctor dengan melakukan uji cold pressor tes! pada subyek laki-laki yang bemmur 20 - 30 tahun. 10 Subyek dibcri aged garlic exiraci 1200 mg per oral, 10 subyek diberi plasebo, kemudian dilakukan pcrncriksaan kadar niiric oxide sebelum perlakuan, sesudah 60` perlakuan dan 90` perlalcuan menggunakan Mtratedilitrite Colorimezric Assay yang dikeluarkan Oleh Cayman Chemical Company. Hasil: Kadar nitric oxide sesudah pemberian aged garlic exrraci terlihat lebih tinggi daripada sebelumnyzg namun sccara statistik tidak bcrbcda bcrmakna (p > 0,05). Demikian juga nilai nitric oxide sebelum dan sesudah perlakuan pada masing-masing kelompok antara dua kclompok, tidak bcrbeda bcrmakna untuk A 60` (p > 0,05) dan A 90` (p > 0,05). Selanjutnya dilakukan uji untuk melihat apakah nilai nitric oxide dad waktu ke waktu tersebut berbeda antara kelompok perlakuan dengan kelompok plasebo, didapatkan hasil (p> 0.0S), dan nilai niiric oxide dari waictu ke waktu tersebut tidak ada kaitannya dengan beda perlakuan (p >o,o5). Kesimpulan: Sediaan aged garlic extract sebanyak 1200 mg yang diberikan per oral kepada manusia cenderung meningkatkan kadar nitric oxide, namun secara sratistik tidak berbeda bermakna. ......Introduction: Aged gmlic extract derives from garlic that has been remained in 15-20% ethanol for 20 months at room temperature so that the active substance in garlic changes into sulfur component that is water-soluble, S-allylcysteine (SAC), and S-allylmercaptocysteine_ Aged garlic extract increase the production of Nitric Oxide (NO), this is happen because SAC stimulate the entry of calcium into endothelial cell, furthermore stimulate endothelial nitric oxide synthase to produce NO. Nitric Oxide that has been formed diftitses immediately into neighboring smooth muscle and activates several mechanisms that cause smooth muscle relaxation and decrease vascular tone. Cold Pressure Test is a standard test to predict whether a person with normotension is at risk to become hypertension if the test results fallen into hyper-reactor category. Hyper-reactor people have sympathetic nerves hypersensitivity and alteration in the production of NO as vasodilator. IfAged garlic extract is able to increase NO level, then vascular tone in a hyper-reactor person can be maintained not to increase when vasoconstriction occur. Objective: Knowing the effects of aged garlic extract to the increase level of Nitric Oxide within blood of hyper-reactor men aged between 20 -30 years. Method: Acquiring the sample by performing cold pressure test to men subject aged between 20-30 years old. Ten subjects were given 1200 mg of aged garlic extract per oral and ten other subjects were given the placebo. Then, an examination been done to check the value ofN0 level before treatment, 60’ atier treatment, and 90’ after treatment using Nitrate/Nitrile Colorimetric Assay produced by Cayman Chemical Compatnt. Result: The value of nitric oxide (NO) level aiter aged garlic extract were given is higher than before, hut statistically does not shown significant difference (p > 0.05). Both does the value of NO level before and atter treatment in each group, between two groups shows no significant difference at A60` (p > 0.05) and A90` (p > 0.05). Furthermore, a test been done to observe whether the value of NO level from time to time were different between the treatment and the placebo group, the result is p > 0.05. In addition, the value of N0 level fiom time to time had nothing to do with the different treatment (p > 0.05). Conclusion: The preparation of 1200 mg aged garlic extract that was given orally to human tends to increase the level of NO, although statistically the increase is not significantly different.
