Abstract

Penelitian ini membahas mengenai model penyebaran penggunaan media sosial dan analisa kestabilan di sekitar titik ekuilibrium serta simulasi numeriknya dengan mengasumsikan populasi individu dibagi menjadi 5 kelas yaitu individu yang rentan terhadap kecanduan media sosial, individu yang menggunakan media sosial tetapi belum timbul kecanduan, individu kecanduan/adiktif media sosial, individu sembuh dari kecanduan media dan individu yang berhenti menggunakan media sosial. Model matematika yang digunakan adalah SEARQS dengan asumsi tidak ada kematian karena kecanduan media sosial. Selain itu, individu yang telah berhenti dari kecanduan media sosial, dapat kembali menjadi individu rentan. Permasalahan yang timbul dari penyebaran penggunaan media sosial yang berlebihan adalah bagaimana mengetahui kapan individu yang kecanduan media sosial akan menghilang dari populasi dan kapan individu yang kecanduan media sosial masih akan tetap ada di dalam populasi. Berdasarkan model, diperoleh titik ekuilibrium bebas kecanduan dan titik ekuilibrium endemik. Analisa kestabilan dilakukan di sekitar titik ekuilibrium bebas kecanduan diperoleh hasil bahwa titik ekuilibrium bebas kecanduan stabil asimtotik lokal jika dipenuhi syarat Ro1. Selanjutnya dilakukan simulasi numerik dengan menggunakan program Matlab menghasilkan jika Ro1 populasi individu yang kecanduan media sosial akan menghilang dari populasi sesaat setelah 10 satuan waktu, sedangkan jika Ro1 individu yang kecanduan media sosial masih ada dalam populasi. In this paper we discussed about the model of social media addiction and stability analysis of the equilibrium point as well as its numerical simulation by assuming the individual population is divided into 5 classes, namely Susceptible individual, Expose individuals, Addicted individuals, Recover individuals. The SEARQS model is used. The assumptios used are no deaths due to social media addiction. In addition, individuals who have quit social media addiction may return to being Susceptible individuals. The problem that arises from the spread of excessive use of social media is how to know when individuals who are addicted to social media will disappear from the population and when individuals who are addicted to social media will still be in the population. Based on the model, an addiction-free equilibrium point and an endemic equilibrium point are obtained. The stability analysis was carried out around the addiction-free equilibrium point and the result was that the addiction-free equilibrium point was locally asymptotically stable if the condition  was fulfilled. Furthermore, a numerical simulation using the Matlab program results if , the population of individuals who are addicted to social media will disappear from the population shortly after 10 time units, whereas if , individuals who are addicted to social media are still in the population.

Abstract

Luka merupakan permasalahan kesehatan dengan tingkat kejadian yang sering terjadi di Indonesia. Pemberian terapi berbahan herbal dapat menjadi salah satu alternatif dalam penyembuhan luka. Sirih merah (Piper crocatum) dan sirih hijau (Piper betle L.) mempunyai berbagai senyawa metabolit sekunder yang berperan dalam penyembuhan luka sayatan pada kulit. Penelitian ini bertujuan untuk mengetahui efektivitas sediaan patch kombinasi ekstrak daun sirih merah dan daun sirih hijau terhadap penyembuhan luka sayat. Hewan coba dibagi menjadi 5 kelompok perlakuan yaitu kontrol positif (plaster povidone iodine), kontrol negatif patch tanpa ekstrak, dan kelompok dengan ekstrak pada beberapa konsentrasi (7,5%, 15% dan 30%). Beberapa parameter yang dilakukan dengan pengukuran panjang luka, pengamatan waktu penyembuhan luka dan infeksi lokal berdasarkan kriteria Nagaoka. Sediaan patch kombinasi ekstrak daun sirih merah dan daun sirih hijau secara statistik tidak menunjukkan perbedaan bermakna terhadap efektivitas dalam penyembuhan luka yang dinilai berdasarkan kriteria Nagaoka dengan beberapa parameter penilaian luka. Namun, pengamatan secara makroskopis pada kelompok K2 (konsentrasi 15%) menunjukkan terjadinya penyembuhan luka yang lebih baik dibandingkan dengan kelompok plaster povidone iodine. Wounds are a health problem that is a frequent occurrence in Indonesia. Providing herbal therapy can be an alternative for healing wounds. Red betel (Piper crocatum) and green betel (Piper betle L.) have various secondary metabolite compounds that play a role in healing wounds of skin incisions. This study aims to determine the effectiveness of a combination patch preparation of red betel leaf extract and green betel leaf in healing cuts on the skin. The experimental animals were divided into five treatment groups: positive control (povidone-iodine plaster), negative control patch without extract, and groups with extract at several concentrations (7.5%, 15%, and 30%). Several parameters were measured by measuring wound length and observing wound healing time and local infection based on the Nagaoka criteria. The combination patch preparation of red betel leaf extract and green betel leaf extract did not statistically show a significant difference in effectiveness in wound healing as assessed based on the Nagaoka criteria with several wound assessment parameters. However, macroscopic observation in the K2 group (concentration 15%) showed better wound healing compared to the povidone-iodine plaster group.

Abstract

Transportasi umum ini penting terlihat dari semakin bertambahnya kebutuhan akan jasa transportasi guna menunjang pergerakan manusia serta barang. Hal ini diakibatkan adanya peningkatan perkembangan penduduk dan perkembangan pemukiman di kota maupun di desa. Jaringan transportasi merupakan hal yang penting yang perlu diperhatikan. Salah satu moda transportasi yang dijadikan alat yang menunjang mobilitas masyarakat adalah kereta api. Sebagian besar orang memilih kereta api sebagai alat transportasi. Namun, jaringan kereta api terkadang banyak terkendala dengan penundaan yang terjadi sehingga terjadi delay atau ketepatan waktu keberangkatan dan kedatangan yang tentu saja merugikan para penggunanya. Alasan yang sering terjadi dikarenakan jalur kereta api yang tidak dapat dilalui dua atau lebih kereta api sekaligus, sehingga mengakibatkan kereta satu harus menunggu kerata yang lain. Dengan demikian, perlu ada penjadwalan yang tepat terhadap jaringan kereta api sedemikian sehingga delay tersebut tidak terjadi lagi. Tujuan dari penelitian ini adalah menjadwalkan aljabar max plus untuk jaringan kereta api DAOP 8 Surabaya agar meminimalisir delay yang biasanya terjadi sehingga mengganggu mobilitas penggunanya. Berdasarkan penelitian ini, diperoleh periode jadwal keberangkatan setiap 101 menit sekali untuk setiap stasiun yang ada di jawa timur.Dengan adanya periode keberangkatan kereta api ini, maka dapat memudahkan dalam menjadwal kereta api sehingga lebih tertata.

Abstract

Infertility cases in the world are increasing in 2020, with 186 million individuals affected worldwide. The most common cause of male infertility is due to decreased sperm quality. Sperm membrane integrity is known to play an essential role in the fertilization ability of spermatozoa. The methanol fraction of Luvunga sarmentosa root extract has the highest antioxidant activity compared to other fractions and can improve sperm motility in vitro. This study aims to determine the effect of the methanol fraction of Luvunga sarmentosa root extract on human sperm membrane integrity and the effective concentration of Luvunga sarmentosa methanol extract fraction to improve sperm membrane integrity in vitro. The samples used were washed human spermatozoa in vitro, then added BWW medium, and incubated at 37℃ for 1 hour with methanol fraction of Luvunga sarmentosa root extract at concentrations of 100, 500, 1000, and 5000ng/ml as well as the control group (BWW only). Furthermore, 100uL of each sample was added to 1mL of Hypo-osmotic swelling (HOS) solution, then incubated at 37oC for 30 minutes to see the integrity of the spermatozoa membrane from the tail swelling. The results showed that sperm membrane integrity significantly increased at 100, 500, 1000, and 5000ng/mL concentrations compared to the control group. The methanol fraction of Luvunga sarmentosa root extract was most effective at a concentration of 100ng/mL. Methanol fraction of Luvunga sarmentosa root extract can improve human sperm membrane integrity.

Abstract

Hemoglobin is an important component of the human body. It aims to transport oxygen and carbon dioxide. Anemia during pregnancy often occurs in the second trimester. Pregnant women tend to be vulnerable to malnutrition since their nutritional needs will increase to satisfy the needs of both the mother and the fetus. Protein intake plays a crucial role in the transportation of iron in the body. Meanwhile, vitamin C serves as a promoter of iron absorption. This research aims to determine and analyze the correlation between protein, iron, and vitamin C intake and hemoglobin levels in pregnant women at Kayon Public Health Center, Jekan Raya District. This research used an analytic observational method with a cross-sectional approach and a purposive sampling technique. Bivariate analysis was also applied by using the Spearman test. The latter results obtain a p-value of 0.748 between protein intake and hemoglobin level; a p-value of 0.222 between vitamin C intake and hemoglobin level; and a p-value of 0.050 between iron intake and hemoglobin level. There was a correlation between iron intake and hemoglobin level, yet there was no correlation between protein and vitamin C intake with hemoglobin level.

Abstract

Sexually Transmitted Infection (STI) is an infection triggered by bacteria, viruses, protozoa, parasites and fungi which is transmitted mainly through sexual contact, including anal and oral. Apart from that, STIs can also be transmitted through direct contact with contaminated objects, for example towels, sex toys, syringes, thermometers, and also through pregnant women to their fetuses or during the birth stage. One age group that is vulnerable to STIs is teenagers. Teenagers are more often encouraged to explore sexual experiences, which can increase the risk of experiencing STIs. One of the problems of teenagers at SMAN 4 Palangka Raya based on the results of interviews with students related to STI cases is the low level of knowledge about STIs. This service activity aims to increase teenagers' knowledge about STIs and spread this knowledge to the surrounding environment. The method used is a lecture containing material about the definition and meaning of STIs, the causes of STIs, symptoms caused by STI-causing agents in both men and women, how STIs are transmitted and how to prevent them. Service activities begin with socialization, implementation and evaluation of results. The implementation of Community Service activities in the form of efforts to increase knowledge about sexually transmitted infections in adolescents at SMAN 4 Palangka Raya was successful, participants enthusiastically listened to the material presented. There was a significant increase in knowledge after counseling compared to the pretest. Counseling can increase students' knowledge about the types of STIs and their complications.
