Research has been carried out about type of birth process and its effect on post-partum estrus post-artificial insemination (AI) of Bali cows in Pujut District, Central Lombok Regency. The aim was to determine the effect of the type of birth process on post-partum estrus of cows. The research used descriptive method with the material were 40 Bali cows in 4 (four) villages, namely Pengengat, Teruwai, Mertak and Bangket Parak. The research variables were the type of birth process and post-partum estrus, as well as supporting variables such as the age of cow, body condition score (BCS), body weight, type of bull semen and days open. The data were statistically analyzed including the mean, standard deviation and percentage, followed by t-test. The results showed that 52.25% of Bali cows in Pujut District gave birth normally and 47.5% suffer light dystocia with birth assistance. The mean age of cows with dystocia was 29.53 ± 5.72 months by the BCS of 2.53, compared to 31.62 ± 5.61 months by the BCS of 2.81 in normal birth. The mean weight was 319.00 ± 29.72 kg compared to 342.81 ± 49.36 kg. The mean days open was 199.13 days compared to 195.67 days and post-partum estrus was 122.00 days compared to 105.00 days. In conclusion, the onset of post-partum estrus and days open in Bali cows that suffer light dystocia with birth assistance is longer than normal birth.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122019131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traumatic brain injury (TBI) is an injury that occurs when a force transmitted to the head or body causes neuropathological damage and dysfunction. TBI is one of the most common head injuries worldwide. This disorder affects 2% of the world's population each year and is the leading cause of death and serious disability in children and young adults. Getting hit or bumped into objects, motor vehicle crashes and falls, and intentional self-injury are the most common causes of TBI. This study aims to determine the histopathological description of brain inflammation in post-traumatic brain injury rats and analyze the relationship between differences in trauma burden and histopathological features of brain inflammation in post-traumatic brain injury rats. This research is an experimental study conducted by giving treatment to the object under study and then observing it. Sampling in this research will use purposive sampling. Where the researcher has determined the criteria of the sample to be used in the study so that it can represent the population. The results of this study indicate that there is a relationship between differences in trauma load and the percentage of rat brain inflammation after experiencing traumatic brain injury. The results of data analysis from this study for the Pearson test obtained a significance value of 0.00 so that there is a correlation between differences in trauma load and the percentage of brain cell inflammation in rats after experiencing traumatic brain injury. The Pearson correlation value of this data is 0.7621 which means a strong correlation. The results showed a significant inflammatory picture compared to the histopathological appearance of rat brain cells in normal samples.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125345838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to increasing the potential for irrigation and boosting the economy from agricultural products on this limited land, it is necessary to know this, so that it can be used as material for consideration in maintaining family food security. Irrigation test activities were also carried out on irrigation uniformity, irrigation distribution and irrigation depth at various irrigation times. Tests were carried out on variations of soil and compost as planting media with the ratios of: 70%: 30%, 50%: 50%, 30%: 70% and four variations in tank water volume. The drip application network uses ½” PVC pipe and dripe on the third floor, while for the first and second levels the Netafim (NTF) pipe is 12 mm. The secondary irrigation network uses ¾ inch, 1 ½ inch and ½ inch PVC in an irrigation test chamber measuring 1.5 m x 4 m and a height of 1 m between levels. The results of the analysis of the test data showed that the uniformity of PVC drip irrigation and NTF combined obtained an average of above 95%, with a very even distribution of water. Irrigation depth obtained at all variations of the water tank level, that is, at 70% of the soil ranges from 3cm -20 cm, at 50% of the soil ranges from 4cm - 20cm and at 30% the amount of infiltration ranges from 2.5 cm - 18.5 cm.

The electrooxidation device consists of a plastic tub with a size (p x l x h) = 20 x 20 x 25 cm which is equipped with an electric stirrer and graphite electrodes using a used battery anode. Graphite electrodes consist of 3 pairs arranged in parallel. This dye degradation experiment was carried out using a batch system (not continuous) with variations in stirring time of 15, 30, 45, and 60 minutes, while the other variables were fixed, namely the concentration of dye 100.24 mg/liter, electrolyte NaCl 2.06 g/liter, 12 V voltage, and a stirring speed of 250 rpm. The dye solution before degradation and after degradation was measured for absorbance using a UV-Vis spectrophotometer at the maximum wavelength, to determine the percentage decrease in absorbance and optimum contact time. The experimental results showed that the percentage decrease in absorbance was constant after a contact time of 30 minutes with an absorbance of 98.36%. This indicates that the optimum contact time for the degradation of Remasol Violet 5R dye is 30 minutes. From the experiments that have been carried out, it can be concluded that the electrooxidation method using graphite electrodes can be used as an alternative waste treatment method, especially in terms of removing dyes in textile industry wastewater.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132441876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted to clearly identify the issues and constraints along the corn value chain, and identify options to address the issues. Quantitative and qualitative menthods were applied to the study. The findings from this study highlight that the corn value chain was very simple where farmers sell their corn to the village level collectors named as palele, then the palele sell the corn to the sub-district level collecotrs, and then they sell to the exporters. It is the roles of these exporters to sell the corn to other island and or to international markets. Issues found in the corn value chain are: the limited supply of fertilisers, broadcasting technique for fertilizer application, corn price fluctuation, and low corn productivity. It is recomended that the local government take few policy options to address the issues, and improve the value chain performance that lead to better smallholder farmers’ livelihood improvement.","PeriodicalId":274989,"journal":{"name":"JURNAL SAINS TEKNOLOGI & LINGKUNGAN","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131477918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
