Abstract

Diabetes mellitus (DM) is one of disease that its incidence increases every year worldwide. The condition of DM can cause various complications caused by oxidative stress. Stichopus hermanii (SH) or golden sea cucumber extract contains antioxidant compounds that have been proven to reduce oxidative stress conditions. The purpose of this study was to investigate the effect of Stichopus hermanii extract on condition of diabetes mellitus by looking at changes in fasting blood glucose, plasma insulin, and malondialdehyde levels in animal models of Wistar rats. This study was a laboratory experimental study using Randomized Control Trial Design with Post-test only control group design. Thirty-five male Wistar rats divided into five groups, i.e normal control group, positive control, negative control and two treatment groups with SH extract dose 8.5 and 17 mg / kgBW for 14 days once daily after induction of Streptozotocin at the Biochemistry Laboratory of the Faculty of Medicine, Airlangga University. Fasting blood glucose level was measured by a glucometer, plasma insulin measured by ELISA and MDA level was measured by a spectrophotometer. Data were analyzed statistically by using One Way ANOVA test and Kruskal Wallis. There were significant results of SH extract can reduce fasting blood glucose (Kruskal Wallis, p=0.030) and MDA (Kruskal Wallis, p=0.042) but not in plasma insulin (ANOVA, p=0.130). The lowest MDA level occurs in the K4 group that given SH extract dose 17 mg/kg BW than another experimental group. As the conclusion, this study showed SH extract can decrease fasting blood glucose and oxidative stress in diabetic-induced rats.

Abstract

Informasi model bawah permukaan dapat digunakan untuk penataan ruang dengan memahami aspek geologi dan potensi bencananya. Metode gayaberat dapat dijadikan solusi untuk mendapatkan model bawah permukaan di daerah Kaliawi yang terletak di pusat kegiatan perekonomian Kota Bandar Lampung. Pengukuran gayaberat telah dilakukan sebanyak 24 titik di Kaliawi. Berdasarkan hasil pengolahan data gayaberat diperoleh peta Complete Bouguer Anomaly (CBA) dan peta anomali regional, Kaliawi yang memiliki pola penurunan dari Tenggara ke arah Barat Laut. Nilai anomali rendah mayoritas berada di daerah Barat dan ditafsirkan merupakan batuan sedimen sedangkan anomali tinggi mayoritas berada di daerah Timur dan diduga merepresentasikan cerminan konfigurasi batuan dasar yang memiliki litologi basalt-andesit. Berdasarkan pemodelan ke depan gayaberat diperoleh nilai densitas sedimen 2.3 gr/cc dan batuan dasar (basalt-andesit) dengan nilai densitas 2.8 gr/cc. Nilai anomali gayaberat yang rendah berpotensi menjadi akuifer. Nilai anomali gayaberat yang rendah juga merupakan zona lemah dan rawan terjadi gerakan massa tanah. Sehingga untuk penataan ruang Kaliawi, daerah Barat direkomendasikan sebagai zona konservasi dan sedikit permukiman sedangkan daerah Timur dapat digunakan menjadi area permukiman penduduk.Kata Kunci: Gayaberat, perkotaan, Kaliawi

Abstract

Gold mining carried out by local communities has a negative impact on environmental conditions, especially pollution in the Kahayan River basin. The purpose of this study was to describe the pollution control carried out by the government in the Rungan River basin which was polluted due to gold mining activities carried out by the community in Parempei Village, Central Kalimantan. The research method used in this study was the observation method. The use of mercury by local gold miners on a small scale is the main cause of pollution in the Rungan River basin, so that it exceeds the acceptable water quality standards. The findings of this study indicate that the efforts made by the government in overcoming pollution in the Rungan River basin are still lacking, which is also caused by several factors such as the lack of binding government affirmation regarding river pollution control, lack of public awareness in protecting the environment, and poor practices in imposing sanctions and law enforcement for miners.

Abstract

According to energy observers from the Institute for Essential Services Reform (IESR) the number of electricity consumers in Indonesia has increased by an average of 6-7% annually followed by an increase in the area of its services. An increasingly broad network is directly proportional to the potential for interference with the transmission and distribution system. The 150 KV Rembang substations is part of the Java-Bali Interconnection electrical system in northern Central Java that supplies electricity to the Rembang and surrounding areas. Rembang 150 KV substation on May 24, 2019, RBG 01 feeder experienced a disturbance behind the RB1-32 recloser and it was recorded that in 2019 PMT it had been tripped 4 times. Besides, there has been a change in equipment in the form of transformer II. These problems indicate the potential for interference that is not anticipated by the protection system, namely Over Current Relay and recloser.  This study evaluates the setting of an outgoing 20 KV OCR protections and recloser on transformer II RBG 01 feeder Rembang 150 KV substation. The scenarios used are calculations with large variations of short-circuit current based on% distance, as well as the calculation of OCR and recloser settings with IEC 60255 standards. Setting currents in the protection equipment is regulated based on current conductivity (KHA) and load current on the recloser. The coordination of the protection settings resulting from this resetting will be compared to the conditions on the ground.  Existing (field) OCR outgoing feeder RBG 01 condition TMS OCR value = 0.228 seconds, Iset = 480 A, and t op = 0.3 seconds. The existing OCR recloser condition TMS OCR value = 0.120 seconds and Iset = 400 A. The results of OCR coordinating outgoing feeder RBG 01 obtained TMS OCR value = 0.135 seconds, Iset = 585 A, and t operation = 0.3 seconds. OCR recloser resetting conditions obtained TMS OCR value = 0.10 seconds, Iset = 240 A and t operation = 0.198 seconds. The resetting conditions have met the IEC 60255 standard because recloser working time is smaller than outgoing work time.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh arus kas operasi, beban operasional, harga pokok penjualan, dan pertumbuhan penjualan terhadap pertumbuhan laba pada perusahaan. Metode analisis yang digunakan dalam penelitian ini adalah regresi linier berganda dengan menggunakan data keuangan perusahaan selama periode tertentu. Hasil penelitian menunjukkan bahwa arus kas operasi memiliki pengaruh positif yang signifikan terhadap pertumbuhan laba. Artinya, peningkatan arus kas operasi dapat berkontribusi pada peningkatan laba perusahaan. Selain itu, beban operasional dan harga pokok penjualan juga berpengaruh signifikan terhadap pertumbuhan laba, namun dengan arah yang berlawanan. Semakin tinggi beban operasional atau harga pokok penjualan, semakin rendah pertumbuhan laba perusahaan. Di sisi lain, pertumbuhan penjualan tidak secara signifikan mempengaruhi pertumbuhan laba. Meskipun peningkatan penjualan mungkin memberikan kontribusi positif terhadap laba, namun dampaknya tidak begitu kuat seperti halnya arus kas operasi, beban operasional, dan harga pokok penjualan. Penelitian ini dapat memberikan wawasan kepada manajer keuangan dan pemangku kepentingan lainnya tentang faktor-faktor yang dapat mempengaruhi pertumbuhan laba perusahaan. Oleh karena itu, manajemen perusahaan disarankan untuk lebih memperhatikan manajemen arus kas operasi, pengendalian beban operasional, dan strategi penetapan harga pokok penjualan guna meningkatkan kinerja keuangan dan pertumbuhan laba perusahaan.
