Abstract

Mount Talang is an area that has geothermal potential and on its surface is found many surface manifestations in the form of hot springs. One of the hot springs that produces silica sinter is at Garara hot spring. A petrographic test was carried out to determine mineral content of the silica sinter. Petrographic testing shows a volcaniclastic, hypocrystalline texture with a massive structure, angular-subangular grain shape, grain size <0.1-3.5 mm. The silica sinter consists of plagioclase, pyroxene, biotite and opaque minerals in a volcanic glass matrix, where volcanic glass has the largest content. Because the position of the area where the hot springs come out is in a volcanic range, the presence of volcanic glass and the abundance of minerals or similar altered minerals shows that the sample is influenced by minerals usually contained in volcanic systems.

Abstract

Usia 6ā€“59 bulan merupakan periode krusial dalam tumbuh kembang anak yang dipengaruhi oleh faktor lingkungan dan psikososial keluarga. Parenting stress merupakan faktor pascakelahiran yang dapat dimodifikasi dan berperan penting terhadap kualitas perkembangan anak. Penelitian ini bertujuan menganalisis hubungan parenting stress. Penelitian ini menggunakan desain metode campuran dengan pendekatan kuantitatif (cross sectional) dan kualitatif (wawancara mendalam). Penelitian ini menggunakan two stage sampling (proportional random sampling untuk pemilihan posyandu dan konsekutif sampling untuk mendapatkan 206 pasangan ibu-anak usia 6-59 bulan). Data dikumpulkan melalui instrumen Denver II dan wawancara dengan kuesioner. Penelitian kualitatif dengan wawancara mendalam yang dilakukan kepada 11 informan. Uji kuantitatif menggunakan chi-square dan uji kualitatif menggunakan triangulasi. Hasil penelitian menunjukkan bahwa ada hubungan stres pengasuhan dengan perkembangan anak diperoleh nilai p<0,05. Dalam penelitian ini, parenting stress memiliki peluang 2,234 kali lebih besar untuk mengalami perkembangan tidak sesuai. Hasil kualitatif dari faktor dominan menghasilkan tiga tema utama, yaitu gangguan interaksi akibat stres pengasuhan, persepsi beban dalam pengasuhan anak serta dampak yang terlihat pada perilaku dan perkembangan anak. Temuan ini memperkuat bahwa stres pengasuhan mempengaruhi kualitas interaksi dan praktik pengasuhan sehari-hari. Kesimpulan penelitian ini terdapat hubungan antara stres pengasuhan dengan perkembangan anak usia 6-59 bulan secara kuantitatif dan kualitatif. Oleh karena itu, diperlukan intervensi yang fokus pada dukungan psikososial ibu dan optimalisasi praktik pengasuhan.

Abstract

Iron deficiency anemia is a common nutritional problem among adolescent girls in Indonesia. According to the World Health Organization (WHO), the prevalence of anemia among adolescents worldwide was 32.5% in 2020. UNICEF data (2021) reported that in Indonesia, the highest prevalence of anemia was found among adolescents aged 13ā€“15 years, at 22.7%. Providing health education about anemia and balanced nutrition is necessary to minimize the incidence of anemia among adolescent girls. This study aims to determine the effect of peer education on changes in knowledge and attitudes among adolescent girls with anemia at MTsN 6 Kota Padang. The study, using a pre-experimental design, was conducted at MTsN 6 Kota Padang from February to August 2025. The sample consisted of 52 adolescent girls with anemia, selected using consecutive sampling. Data were analyzed using univariate and bivariate methods, with the Wilcoxon test (pā‰¤0.05). The results showed that 83% of the female students experienced an increase in knowledge (p=0.001), while 69% experienced an increase in positive attitudes (p=0.001). Statistically, there was a significant difference in knowledge and attitudes among anemic female adolescents after receiving peer education.

Abstract

Stunting is a condition of a short body based on the height-for-age index. Clean and healthy living behavior is an important behavior that can prevent stunting. The purpose of the study was to determine the relationship between clean and healthy living behavior and the incidence of stunting in toddlers at the Koto Panjang Ikua Koto Health Center. This study is an observational study with a cross sectional approach, he sampling technique used was proportional sampling with 82 respondents. Data were collected using a microtoise, the maternal and child health book and a questionnaire. The data were analyzed using chi-square and logistic regression test. The results showed a relationship between weighing toddlers and the incidence of stunting (p=0,003), exclusive breastfeeding is related to the incidence of stunting (p=0,009), the habit of washing hands with soap is related to the incidence of stunting (p=0,039), the use of healthy latrines is related to the incidence of stunting (p=0,017), eradication of mosquito larvae is related to the incidence of stunting (p=0,032). The results of the multivariate analysis showed that weighing toddlers had the most dominant relationship with the incidence of stunting (OR:6,376). Concluded that clean and healthy living behavior is significantly associated with the incidence of stunting.

Abstract

This activity aims to apply Bernoulli's law to the piping system in the hydrant pump to meet the needs of residents in bathing, washing, and irrigating the fields. The activity begins with conducting a site review survey, counseling and determining the location of pump placement, making pumps and towers, and lifting pumps and towers to the location. Then the activities at the location are divided into several parts, including the manufacture of civil and mechanical pump systems and testing the success of the pump system. This activity carried out the manufacture of hydrant pumps by installing pipes using Bernoulli's law to meet the needs of the residents of Jorong Batu Gadang, totaling 30 families and irrigating rice fields covering an area of 78 ha, which are rainfed rice fields. The results of the activities carried out at Nagari Katialo, Jorong Batu Gadang in applying the concept of Bernoulli's Law to the piping system at the hydrant pump made water faster to reach the highest point of the piping system that had been made. As for the difference in height between the position of the pump and the water level in the reservoir (tank) of 30 meters, the flow of water rising to the tank is 2 liters/second. The people of Jorong Katialo can already enjoy the water stored in the reservoir. The success of this pump system is shown from less than 10 minutes of testing the water successfully to the water reservoir above the tower with a height difference of 30 meters from the placement of the hydrant pump.

Abstract

Nobita Hill is one of the areas being developed as a tourist attraction in the city of Padang. Above Nobita Hill is a beautiful view, and you can see the picture of Padang City. However, the hilly topography with steep slopes makes this area prone to landslides. This activity aims to map the potential for landslides on Novita Hill. Activities start from preparation, implementation in the field, and evaluation. Field activities are carried out in two stages. The first stage is an experiment to map the landslide potential. The second stage is socialization. The target audience for this activity is the Village Head of Jua Nan XX Village and its officials and the community around Nobita Hill. The results of the study and mapping were disseminated to the village administration and community leaders involved in the development of the Bukit Nobita tourism area, which was carried out on November 16, 2022. The result of tourist objects often changes land use and cover. However, mitigation of the potential for landslides in this area has never been done. Therefore, the Andalas University Physics Department team mapped the potential for landslides on Novita Hill for six months, using microseismic and geoelectric methods. This activity obtained a map of the distribution of dominant frequencies, a map of the distribution of amplification, and an identification of slip planes concerning the potential for landslides on Nobita Hill. Furthermore, the results of the mapping and mitigation efforts have been disseminated to the village administration and community leaders involved in the development of the Bukit Nobita tourism area. This activity was carried out well. The landslide potential distribution map obtained from this activity is input for the community and stakeholders in developing the Buki Nobita tourist attraction that is safe from disasters.

Abstract

Cakupan ASI eksklusif di wilayah Puskesmas Air Dingin sangat rendah (31,5%), sejalan dengan tingginyamasalah gizi balita setempat. Beban ganda (double burden) ibu bekerja menjadi tantangan utama dalammempertahankan laktasi. Penelitian ini bertujuan untuk mengeksplorasi secara mendalam faktor-faktordeterminan keberhasilan dan kegagalan ASI eksklusif pada ibu bekerja di wilayah tersebut. Desain penelitianmenggunakan metode kualitatif dengan pendekatan deskriptif. Pengumpulan data dilakukan melalui wawancaramendalam, observasi, dan dokumentasi terhadap 18 informan (12 ibu bekerja, 3 bidan, 3 kader) yang dipilihmelalui teknik purposive sampling. Analisis data menggunakan thematic analysis dan triangulasi. Hasilpenelitian menunjukkan bahwa dukungan nyata (instrumental) dari suami merupakan faktor paling dominandalam menentukan keberhasilan ASI eksklusif, bahkan kemampuannya melampaui hambatan minimnya fasilitasdi tempat kerja. Peran nenek sebagai pengasuh berdampak ganda; menjadi penghambat jika kurang literasi danmenjadi pendukung telaten jika memahami manajemen laktasi. Keberhasilan ibu bekerja juga sangat ditentukanoleh strategi adaptasi proaktif (anticipatory coping) dengan menyiapkan stok ASI perah sejak cuti melahirkan,kemampuan negosiasi waktu di tempat kerja, serta fasilitas penitipan anak yang kooperatif. Intervensi edukasi kedepannya wajib melibatkan partisipasi aktif suami dan pengasuh pengganti.
