Abstract

Research has been carried out to detect the presence and distribution of rocks containing metallic minerals. Almost every object used every day contains metal elements, so the presence of metal is very important to support every human activity. The presence of metal minerals in nature is generally quite a lot, but the types of metallic minerals vary. The geomagnetic method is a geophysical method that can detect subsurface rocks containing metallic minerals based on the difference in the magnetic field between the rock and the surrounding rock. Processing of geomagnetic data obtained in the field begins with daily correction and correction of the earth's main magnetic field (IGRF). The correction results obtained are anomaly of the earth's magnetic field which is distributed horizontally on the surface. The results of the analysis in the form of local magnetic field anomalies (∆H) are divided into 3 (three) regions, the first having a value between -236.5 nT to -8 nT (nano tesla) as an area that has a high local magnetic field anomaly value. Second, the value of -377.2 nT to -236.4 nT as an area that has a moderate anomaly value. Third, the low anomaly values ranged from -778.4 nT to -377.1 nT. Areas that have high local magnetic field anomaly values are interpreted as ultramafic rocks, which are source rocks of nickel lateric deposits rich in ferromagnesian minerals, distributed in the southeastern part of the study area.

Abstract

Plants as medicinal ingredients have potential as antimicrobials and antioxidants, with various molecules that can protect the human body from pathogens and cellular oxidation. This is closely related to the secondary metabolitescontained in these plants. Currently there are several bacteria that are resistant to antibiotics, therefore it is necessary to find an alternative to overcome this resistance by conducting research on medicinal plants. Sekilang (Embeliaborneensis) is a plant that is used by the Dayak tribe in Kalimantan as an ingredient for catching fish, repelling leeches and hair care and does not rule out having medicinal properties. So it is necessary to do research on these plants, especially the bark. The purpose of this study was to determine the antibacterial activity of sekilang bark extract against Propionibacterium acnes and Staphylococcus epidermidis bacteria. Extraction of the active substance was carried out by maceration with ethanol solvent and antibacterial activity test using the disc diffusion method. The results of phytochemicalscreening showed that the bark extract of sekilang contains saponins, flavonoids, alkaloids and tannins. The results of the antibacterial activity test against Propionibacterium acne at a concentration of 2.5%; 5% ; 10% and 20% are 6.5 mm, respectively; 8.36 mm ; 7.5mm; 7.33mm. Antibacterial activity against Staphyllococus epidermidis at a concentration of 2.5%; 5% ; 10% and 20% are 7.0 mm, respectively; 7.7mm; 6.33mm; 7.8mm. It was concluded, that the bark extract of sekilang have antibacterial activity against Propionibacterium acne and Staphyllococus epidermidis with moderate category. The positive control used was clindamycin and the negative control was Dimethyl sulfoxy.

Abstract

Saat ini pertumbuhan penduduk semakin pesat dan tentunya akan berbanding lurus dengan pertumbuhan kebutuhan transportasi. Pada saat yang sama, perlu dipastikan bahwa infrastruktur pendukung penggunaan transportasi dalam keadaan baik, jika tidak maka aktivitas pengguna transportasi akan hancur. Penelitian ini bertujuan untuk mendapatkan volume lalulintas, skor kerusakan jalan dan beban standar (CESA5) terhadap kerusakan pada ruas Jalan Gubernur Sarkawi. Metode Bina Marga merupakan metode yang akan digunakan, yang mana dengan menggunakan analisis regresi dan korelasi, sehingga untuk mendapatkan hubungan tersebut dengan nilai rdan  yang menunjukkan besarnya pengaruh antara tingkat kerusakan jalan dengan volume lalu lintas dan beban lalu lintas. Dari analisa yang dilakukan mendapatkan hubungan antara volume lalu lintas per jenis kendaraan dan beban standar terhadap kerusakan jalan, sehingga  dari analisa yang dilakukan mendapatkan hubungan terkuat adalah untuk jenis kendaraan mobil penumpang dan kendaraan ringan terhadap jenis kerusakan jalan dengan nilai r sebesar 0,2179, untuk jenis kendaraan 5B (bus besar) terhadap jenis kerusakan mendapatkan nilai r sebesar 0,2184, untuk jenis kendaraan 6A (truk 4 roda 2 sumbu), untuk jenis kendaraan 6B (truk 2 sumbu 6 roda) terhadap jenis kerusakan mendapatkan nilai r sebesar 0,6436, untuk jenis kendaraan 7A1 (truk 3 sumbu) terhadap jenis kerusakan mendapatkan nilai r sebesar 0,2074, untuk jenis kendaraan 7C1 (truk 4 sumbu) terhadap jenis kerusakan mendapatkan nilai r sebesar 0,4498, untuk jenis kendaraan 7C2A (truk 5 sumbu tandem) terhadap jenis kerusakan mendapatkan nilai r sebesar 0,7432 dan untuk LHR (smp/jam) terhadap kerusakan mendapatkan nilai r sebesar 0,8787. Sedangkan untuk hubungan beban standar (CESA5) terhadap skor kerusakan jalan mendapatkan nilai r sebesar 0,7263. Dari analisa yang dilakukan untuk jenis kendaraan yang berpengaruh adalah kendaraan 7C2A (truk 5 sumbu tandem) dengan intepretasi kuat dan untuk beban standar mendapatkan nilai kuat hal ini dikarenakan beban kendaraan yang melewati jalan tersebut secara berulang.

Abstract

Kualitas semen setelah penampungan mengalami penurunan apabila tidak ditangani dengan baik.    Tujuan penelitian ini adalah  mengetahui pengaruh hubungan Superoksida Dismutase (SOD) dengan abnormalitas dalam tingkat pengencer dan lama simpan pada semen mentog yang di suhu kamar.    Mentog yang digunakan dalam  penelitian ini adalah 4 ekor ternak entog  jantan berumur sekitar 1,5 – 2 tahun.       Metode penelitian yang digunakan metode eksperimental dengan Split Plot pola petak terbagi.   Faktor pertama sebagai Petak Utama adalah tingkat pengencer yaitu 0(A0); 5 X(A1);10X(A2) dan 15X (A3),  faktor kedua sebagai Anak Petak adalah lama simpan  0(B0); 60 (B1); 120  (B2) dan 180 menit yang disimpan  pada  suhu kamar.     Berdasarkan hasil tersebut bahwa pada Tingkat pengenceran dan lama simpan semen di suhu kamar mentog tidak berpengaruh nyata terhadap abnormalitas dan aktivitas Superoxida Dismutase (SOD).

Abstract

Degenerative disease is a contributor to death from non-communicable diseases (NCD) in the last 10years which has increased from 41.7%. The latest survey in Indonesia shows PTM dominates the top 10 causes ofdeath in all age groups, with stroke, which is a complication as the number one cause of death. This studyaims to determine the relationship between length of smoking and coffee drinking habits with the incidenceof hypertension in the working area of the Banjarmasin City Health Center which was carried out in 2019.This type of research is an analytical survey with a cross-sectional research design. The subjects in this studyamounted to 57 respondents, consisting of male active smokers and consuming coffee. Data were obtainedthrough questionnaires and direct interviews as well as physical examination in the form of blood pressuremeasurements by puskesmas officers, which were then analyzed by chi-square test (α=0.05). The results ofthe statistical test showed that there was a relationship between length of smoking and the incidence ofhypertension (P=0.000), and the habit of drinking coffee with the incidence of hypertension (P=0.002).Suggestions that can be given in research are for puskesmas to further increase public knowledge abouthealth through counseling, especially about the incidence of hypertension, for health workers to optimizecounseling about the incidence of hypertension, especially for men who smoke and consume coffee.experience and add insight, and for other researchers can be used as basic data for further research.
