Abstract
We employed molecular dynamics simulation to explore the melting dynamics of Gold thin film due to ultrashort high-intensities laser irradiation. The film has dimension of 10 nm x 10 nm in lateral periodic condition and thickness 10 nm with free condition. The system is suppressed by the laser energy slightly above melting threshold and simulated under homogeneous and instantaneous energization. Within several ps the system already melt and the evolution are followed based on trajectory of each atom dynamics. During the expansion of the film, we also performed the local structure change based on Common Neighbor Analysis (CNA) method. Structure factor analysis indicated that the film is melted completely at the end of simulation, t = 20 ps.

Abstract
Abstract The position of customary sanctions in resolving non-performing loans in Kerobokan Customary Village LPD is one type of banking law that is legally required to obtain legal protection so that legal certainty is clear to LPD customers. Legal protection for LPDs in this case is enforced because the legal umbrella is clearly stipulated in the Regional Regulation concerning LPD. Legal protection for PLD includes all LPD rights and obligations in the Regional Regulation concerning LPD, so that when there is bad credit by customers originating from outside the traditional village of Kerobokan basically based on "bad faith" with the aim of implementing civil sanctions and social sanctions so that all customers originating from either the Kerobokan traditional village or outside the Pakraman village are bound by a credit agreement. From this, it can be seen that the legal protection of the Kerobokan LPD in dealing with bad credit can be done by means of involving Bendesa Adat as an authority that has authority in traditional villages dealing with bad credit in implementing social sanctions. Forms of legal protection for LPD Kerobokan in resolving bad credit, namely legal certainty in the credit agreement must be clear the rights and obligations of the parties. And when one of the parties violates, the sanctions are expressly regulated in the credit agreement. Settlement of bad loans for customers given outside the Kerobokan Customary Village is a preventive legal effort, meaning that when signing a credit agreement it is understood that the rights and obligations of the parties and repressive actions mean that the parties are obliged to carry out the credit agreement in good faith. The application of civil law sanctions in the form of compensation and customary sanctions are social sanctions in the form of being broadcast in village paruman (community), deactivated as citizens (krama) banjar /village by customary villages and those who are convicted of criminal acts applied by imprisonment by the formal justice as a deterrent effect.

Abstract
Regression of the corpus luteum (CL) is characterized by loss of the capacity to synthesize progesterone (P4) and tissue degradation by apoptosis (functional and structural luteolysis). Luteinizing hormone (LH) is one of the most potent stimulators in progesterone production by corpus luteum (CL) of most mammals, including cow. This research hypothesized that LH suppresses apoptosis of bovine luteal steroidogenic cells (LSC). We examined the effect of LH on cell death such as cell viability and DNA fragmentation factors which related with apoptosis. Cultured bovine LSC obtained from the CL at the mid stage (Days 8–12 of the cycle) were treated for 24 h with recombinant human tumor necrosis factor alpha (TNF; 2.9 nM) and recombinant bovine interferon gamma (IFNG; 2.5 nM) in the presence or absence of LH (0.34 nM). LH reduced the levels of cell death in the LSC induced by TNF and IFNG (P<0.05). Furthermore, DNA fragmentation induced by TNF and IFNG was observed to be suppressed by LH. In conclusion, LH affects viability of luteal cells as an anti-apoptotic factor in bovine CL by increasing cell viability and suppressed DNA fragmentation. This suggests that LH plays luteoprotective roles in bovine CL by suppressing apoptosis of LSC.

Abstract
Neem is a herbal plant that can be used as male contraceptive, by preventing the penetration of spermatozoa in the process of in vitro fertilization. However, the mineral content found in the seeds and leaves of neem can induce oxidative stress in mice, characterized by increased lipid peroxidation potential in the spermatozoa. This study aimed to evaluate the malondialdehyde levels of spermatozoa were epidydimal in mice. To calculate MDA levels in spermatozoa a standard thiobarbituric acid (TBA) method is used. The first group was plot as a control. The four groups were orally treated by neem leaves (two groups) and seeds extract (two groups) in 0.5 mL/mouse/day at doses 0.25 and 0.50 mg/kg bw each for 36 days then were sacrificed. The other four groups were treated same as those in the previous four groups and sacrificed at 36 days post last treatment. Data were analyzed by randomized completely design (RCD) in the test differ of 5%. The results showed that the administration of seed and leaves of water extract of neem did not reduce the MDA levels of sperm mice. The conclusion that the mineral content of neem extracts (seeds and leaves) are safe to use.

Abstract. Wolff-Parkinson-White (WPW) syndrome is one of the most common pre-excitation syndrome. Accessory pathway formed between the atria and ventricles become conduction path other than the atrioventricular node. The occurrence of atrial fibrillation (AF) in the WPW syndrome cases are quite rare, and seldom reported in the medical literature. WPW syndrome that have a tachyarrhythmia has a specific treatment and contraindications, thus giving preferred treatment should avoid the potential occurrence of ventricular fibrillation (VF). We describe adult male presenting with a very rapid, irregular wide QRS complex tachycardia, with hemodynamic instability. Successful cardioversion performed in the emergency room (ER). ECG results after cardioversion showed normal sinus rhythm with accompanying evidence of accessory pathway in accordance with WPW type A with the localization of the LV free wall. Medical personnel need special attention in emergency cases. AF with aberrant conduction and ventricular tachycardia are the very first thing to be considered in cases of wide QRS complex tachycardia. However, medical personnel need to consider that WPW syndrome accompanied with AF will give an increased heart rate (> 200 x / min), wide QRS complex and irregular rhythm, especially when choosing a pharmacological therapy. Several hypotheses which can cause AF in patients with WPW including spontaneous degeneration atrioventicular reciprocating tachycardia (AVRT), electrical properties accessory pathway, accessory pathway effects on atrial structure and vulnerability of intrinsic atrial muscle. The location of accessory pathway and also the possibility of a hidden track of accessory pathway that sometimes gives an overview of less obvious delta waves, but does not rule out the WPW syndrome in this case. AF has a significant prognostic in WPW syndrome. This condition can be life-threatening if there is very rapid ventricular response. The use of drugs that slow AV conduction block is not recommended.

This study aims to determine the effect of Jeruju leaf extract (A. illficolius) on the decrease of fasting blood glucose levels of rats and to know the most effective dose of A. ilcifolius extract on the reduction of fasting blood glucose levels of rats.This type of research is an experimental study of biomedical research design. The stages of this study consisted of sample preparation, identification of A. ilcifolius plant, leaf extraction of A. ilcifolius, qualitative analysis of saponin and tannin using thin layer chromatography method. Ethanol extract of A. ilcifolius with various doses, antidiabetic test in rats induced streptozotocin with categorized 15 animal samples into two control groups and three treatment groups and measured blood glucose level, followed by data analysis using ANOVA.The lowest activity occurred in negative control group, increased at dose 500 mg/kg, positive control and dose 250 mg/kg while the highest occurred in dose group 125 mg/kg. The result of statistic test with the parameter of decrease of fasting blood glucose level of the male rat of Wistar strain, in a group of jeruju leaf extract with dose 125 mg/kg and 250 mg/kg showed the significantly different result with a negative control group. Jeruju leaf extract with dose 125 mg/kg and 250 mg/kg have antidiabetic activity.

Abstract
The research about illegal heap point of solid waste was conducted to identify the quantity of illegal solid waste heap point, to measure the volume and composition of solid waste along Segment 6 Ciliwung Riverbanks. That was done as a response to river pollution caused by solid waste. Calculations of the volume and compositions of solid waste was carried out for three days in five locations, namely riverbank in area of Manggarai (Location 1), Kebon Manggis (Location 2), Menteng (Location 3), Kwitang (Location 4), and Kebon Sirih (Location 5). The research shows that there is 22 illegal heap points of solid waste consisting of 93.38 m3 solid waste volume. The highest volume of the illegal heap point of solid waste was located in Kebon Manggis Area with 34.64 m3 and the lowest volume was located in Kebon Sirih Area with 1,53 m3. The average compositions of solid waste consisting of 45.56% organic waste and 54.44% non-organic waste with the highest percentage are the plastic waste 18.6% and the lowest percentage is rubber/leather waste 2.01%. The existence of the illegal heap point of solid waste in riverbank has the potential to decreasing water quality of Ciliwung River especially in Segment 6.

Abstract
Landslides are an activity of the process of disturbance of balance which causes the movement of the soil and rocks from higher ground to lower ground. Boyolali District is one of 35 cities / regencies that have a high level of vulnerability to the occurrence of landslides. In this research, the mapping of landslide-prone areas using landslide-causing parameters such as thiessen rainfall, soil type, drainage, slope, and land cover. From these parameters will be processed and analyzed by using the scoring method, where scoring is a calculation system that can be used as a control system and problem solving that can be used to detect landslide areas in Boyolali District. In the process of analysis is done by using the features of spatial analysis tools in the form of Overlay software Qgis and R Studio. Then we will get the result of the map of landslide vulnerability level that has 3 classes of vulnerability, including low vulnerability class, medium vulnerability class, and high vulnerability class.

Abstract
The results of previous studies indicate that there are several learning models that have the potential to improve students competencies in reviewing Produk Kreatif dan Kewirausahaan (PKK). Through iMindmap media presented by teachers, vocational students have the opportunity to develop project scenarios based on local potential using a map business. This experimental study aims to determine the effectiveness of the mapping-project learning model by using iMindmap media based on local potential to improve the competency of student entrepreneurship. The mapping-project instrument was developed by researchers and validated by experts. The results showed that the project-mapping learning model using iMindmap media based on local potential could improve student competence in analyzing business opportunities using SWOT analysis, and designing prototypes of superior products based on local potential using a business map. This study recommends that with the mapping-project model, students ability to explore PKK material becomes more profound, meaningful, and student-centered. Future research is needed to analyze the contribution of mapping projects by using iMindmap media on exact learning.
