Abstract

Modernisasi mengubah pola aktivitas manusia dalam rentang waktu 24 jam. Dewasa ini banyak pola aktivitas manusia yang bergeser ke malam hari sehingga terjadi  peningkatan aktivitas dan paparan cahaya hingga malam hari. Pergeseran pola aktivitas ini diduga akan mengubah ritme jam biologis dan dapat menimbulkan stres serta gangguan vitalitas seseorang. Namun kajian tentang pengaruh perubahan fotoperiode terhadap respon stres serta parameter reproduksi masih jarang dilakukan. Penelitian ini menggunakan hewan model mencit SW jantan berumur 4 minggu sebanyak 25 ekor yang dibagi ke dalam 4 kelompok perlakuan berdasarkan durasi fotoperiode yang digunakan yakni 0T, 6T, 18T, 24T dengan 12T sebagai kelompok kontrol (T = durasi terang dalam jam). Intensitas cahaya yang digunakan dalam penelitian ini adalah sebesar 100-110 lux. Seluruh hewan uji didedahkan dengan masing-masing perlakuan fotoperiode selama 2 bulan. Parameter yang diukur meliputi kadar kortikosteron plasma dan berat badan sebagai parameter respon stres, serta kadar testosteron plasma, jumlah sperma dan berat testis sebagai parameter reproduksi. Pengukuran parameter berat badan dilakukan selama pendedahan, sedangkan pengukuran parameter lainnya dilakukan setelah pendedahan fotoperiode. Hasil pengukuran menunjukkan bahwa fotoperiode 0T dan 24T dapat meningkatkan kadar kortikosteron plasma secara signifikan dari kelompok kontrol (p

Abstract

Diabetes mellitus (DM) adalah penyakit kronis yang ditandai dengan kadar glukosa darah (KGD) yang tinggi (hiperglikemia) akibat pengaturan homeostasis glukosa tidak berjalan sempurna. Penelitian saat ini menunjukkan bahwa stres oksidatif ikut berperan dalam berkembangnya DM. Makanan yang mengandung polifenol cukup menarik perhatian karena peran polifenol sebagai antioksidan dan mampu mengikat radikal bebas sehingga diduga dapat mengurangi resiko terjadinya penyakit DM kronis. Oleh karena itu, penelitian ini dilakukan untuk mengetahui bagaimana pengaruh antioksidan polifenol terhadap mencit yang dikondisikan DM. Hasil penelitian menunjukkan bahwa kelompok mencit DM yang diberi polifenol (kelompok A, B, C) memiliki KGD yang lebih rendah secara signifikan dibandingkan kelompok O (Kontrol DM) dan memiliki toleransi glukosa oral yang lebih baik dibandingkan kelompok O (Kontrol DM). Analisis imunohistokimia menunjukkan bahwa  pulau Langerhans pada kelompok mencit yang diberi polifenol (A, B, C) dan kelompok normal (K) memiliki diameter >100µm, sebaliknya pada kelompok O (Kontrol DM) memiliki diameter 100µm, although group O (DM group) have diameter

Abstract

Land is a form of gift given by God, but human has given brain to think the challenges of live like the land problems, so that the government tries to regulate it properly. The problems in this thesis are: 1) How to regulate ownership of agricultural land rights that exceeds the maximum limit based on Act No. 56 (Prp) of 1960 concerning the Determination of Agricultural Land Areas? 2) How is the action taken by the Land Office towards ownership of agricultural land rights that exceeds the maximum limit? The method used is juridical empirical, with descriptive analytical specifications. The method used in this research is an empirical juridical approach. The results of this study are: (1) The regulation of ownership of agricultural land rights that exceeds the maximum limit is based on Act No. 56 (Prp) of 1960, namely that the provisions regarding land restrictions state that the application for ownership rights as referred to in Article 4 paragraph 1 of Act No. 56 (Prp) 1960 was limited to a maximum land area of 2000 m2. 2) The steps of the Land Office in implementing Act No. 56 (Prp) of 1960, namely the need for a concept of supervision and control over control of land rights, given the various problems that often arise such as in land registration activities.

Abstract

Porous Concrete is a type of Concrete that has a cavity in its structure that allows liquid to flow through the cavity. This study aims to determine the effect of adding Master Ease 5010 admixture on the compressive strength and absorption capacity of porous Concrete. The method used in this research is an experimental method by making different tests in the laboratory. The sample used is 10 x 20 cm with a concrete age of 28 days. The tests carried out include compressive strength testing and absorption testing. The absorption test used the falling head method based on the ACI 522R. The results of the normal compressive strength test = 0.28 Mpa, the addition of Master Ease 5010 3% = 0.31 Mpa, and the addition of Master Ease 5010 5% = 0.416 Mpa while testing the absorption of Normal Porous Concrete = 1.406 mm/s, addition of Master Ease 5010 3% = 1,946 mm/s, addition of Master Ease 5010 5% = 2.196 mm/s. From these results, it can be seen that the addition of Master Ease 5010 is able to increase the compressive strength and absorption value of porous Concrete.

Abstract

The development of technology in the transportation sector is increasingly advanced, many renewable innovations are continuously being developed. Various studies have been carried out to find the best solution for finding new innovations. The management of LLDPE plastic waste and cigarette filters into a modified asphalt mixture is an example of a renewable technology. The purpose of this study was to determine the impact of adding LLDPE plastic waste and cigarette filters into the modified asphalt mixture, with a variation of 20% LLDPE and cigarette filters 5%, 10%, 15%. The results showed that the addition of the mixture to the modified asphalt, there was a decrease in the value of Stability, MQ, VIM, VMA, VFB, and Flow.

Abstract

Betel nut (Areca catechu) was proven to have antihyperglycemic activity through increased PI3K pathway in the GLUT4 translocation in cells. However, research on the ethanol extract of betel nut in Indonesia is still limited. The main problem in this study was whether the ethanol extract of betel nut could improve glucose tolerance in a two-hour postprandial period and whether the ethanol extract of betel nut could induce GLUT4 translocation in skeletal muscle cells of mice induced hyperglycemia. Glucose tolerance test results showed that treatment of the ethanol extract of betel nut for 24 days with all doses tested: P50,100,150,200 and 250 mg/kg body weight could improve glucose tolerance in a two-hour postprandial period. The protein electrophoresis of that fasting and one hour postprandial state treatments resulted an increase in GLUT4/βActin density ratio of P250 group compared to negative and positive controls. In this case, GLUT4/βActin density ratio of P100,P200 and P250 were higher than that GLUT4/βActin density ratio of P50 and P150. Increased in GLUT4/βActin density ratio showed enhancement of the GLUT4 in skeletal muscle cells in fasting and one hour postprandial state after treated with ethanol extract of betel nut.
