Abstract

Bencana kekeringan yang terjadi akhir-akhir ini menimbulkan berbagai jenis penyakit, rawan pangan dan menurunnya pasokan air bersih yang merupakan kebutuhan utama manusia. Kekeringan sebagian besar diakibatkan oleh gangguan keseimbangan hidrologis seperti terjadinya degradasi aliran sungai yang beralih fungsi yang menyebabkan terganggunya sistem peresapan air tanah dan pendangkalan waduk atau tempat penampungan air yang menyebabkan daya tampungnya menurun.Pendangkalan tersebut akan membuat cadangan air yang tersimpan menjadi lebih sedikit untuk persediaan air di musim kemarau.Kalimantan Selatan termasuk daerah yang memiliki ancaman persoalan kelangkaan air bersih terutama di wilayah Banjarmasin.Dalam penelitian ini penulismerencanakan penerapan teknologi pemanenan air hujan pada Masjid Agung Banjarbaru Kalimantan Selatan sebagai salah satu cara untuk memenuhi kebutuhan air baku jamaah dalam kegiatannya di lingkungan Masjid Agung. Metode yang digunakan adalah pengumpulan data dan pengolahan data. Dari hasil perhitungan jumlah volume curah hujan yang di dapat melalui atap bangunan, menunjukkan bahwa Volume air yang dihasilkan oleh hujan adalah 1.785,60 m³. Sedangkan kebutuhan air baku setiap bulannya dihasilkan sebesar 1.350m³.Volume suplai air hujan > dari volume kebutuhan air. Sehingga dapat disimpulkan bahwa air hujan dianggap dapat memenuhi kebutuhan air bersih pada kawasan tersebut. Melalui kolam-kolam penampungan air hujan yang juga berfungsi sebagai elemen estetika bagi bangunan, air hujan dialirkan ke ruang-ruang wudhu dan kamar mandi. Kolam pemanenan air hujan yang direncanakan berjumlah 4 buah, di setiap kolam diharapkan dapat menampung volume tampungan air hujan sebesar>446, 40 m³.

Abstract

Background: An ambulance is a vehicle designed to be able to handle emergency patients, provide first aid and carry out intensive care while on the way to a referral hospital. Ambulance operations require a large amount of funds obtained from APBD funds through tariffs that were passed through the DKI Jakarta Governor Regulation five years ago. For this reason, a new tariff is required to adjust to current conditions. Objectives: The purpose of this study is to calculate the unit cost of ambulance services in DKI Jakarta to be a consideration in the tariff setting policy in DKI Jakarta province. Research Metodes: This study uses a quantitative descriptive approach to obtain information about the unit cost of the Jakarta ambulance production unit. The method used is the calculation of real cost using the basis of the causes of costs. This research was conducted at the DKI Jakarta Emergency Ambulance using secondary data on investment costs, operational costs and maintenance costs in 2018. Results: The total cost of emergency ambulance in 2018 is known that the proportion of three cost components, namely operational costs, is 76%, followed by investment costs of 20% and maintenance costs of 3%. The calculation of the total cost of medical evacuation using the double distribution method is Rp. 98,915,016,805.00 divided by the number of medical evacuations in 2018 of 37,564 activities, the unit cost of medical evacuation for the AGD of DKI Jakarta Health Office is Rp. 2,633,215.00 without subsidies. APBD costs, while if the subsidy component is included in the calculation, the unit cost for one trip to the AGD of the Health Office is Rp. 604,071.00. This is still far above the current tariff of Rp. 450.00, so the cost recovery rate (CRR) is still below. 100%. Conclusion: From the three cost components consisting of investment, operational and maintenance costs,the largest proportion was operational costs at 76%. The Cost Recovery Rate has not reached 100% so that the existing rates have not covered the costs incurred. Keywords: ambulance; price fixing; unit cost

Abstract

Every parent wants to have the child they want. Parents want to have children who are perfect physically, mentally, and spiritually. But in reality not all parents have this opportunity, in some cases, there are some of them who have children who experience mental retardation such as Down syndrome. One of the factors that influence the caregiver's burden is social support, where social support can be provided by a community. This research is a correlational quantitative research. This objective of the study was to determine whether there is a correlation between a sense of community and the burden of caregivers on parents who have children with Down syndrome. The population in this study were parents who had children with Down syndrome. The sample in this study amounted to 142. The sampling technique in this study was carried out by purposive sampling technique. The instrument used in this study was a caregiver burden scale consisting of 38 items (31 valid items and 7 invalid items) with a reliability coefficient of 0.873 and a sense of community scale consisting of 34 items (30 valid items and 4 invalid items). Reliability coefficient was 0.915. The results of calculations with data processing software, obtained a sense of community is in the high category and caregiver burden is in the low category. Hypothesis testing was carried out using the Spearman correlation formula resulting in a rho value of -0.473 with a significance value of 0.000. Thus the hypothesis which reads that there is a negative correlation between sense of community and caregiver burden on parents who have children with Down syndrome is accepted. The higher the sense of community, the lower the caregiver's burden. Vice versa, the lower the sense of togetherness, the higher the caregiver's burden. Setiap orang tua pasti mendambakan memiliki anak yang sesuai dengan yang mereka idam-idamkan. Para orang tua ingin memiliki anak yang sempurna baik secara fisik, mental, maupun rohani. Namun pada kenyataannya tidak semua orang tua memiliki kesempatan tersebut, pada beberapa kasus, ada sebagian dari mereka ditakdirkan memiliki anak yang mengalami retardasi mental seperti down syndrome. Salah satu faktor yang mempengaruhi caregiver burden adalah dukungan sosial, dimana dukungan sosial dapat diberikan oleh suatu komunitas. Penelitian ini merupakan penelitian kuantitatif korelasional. Penelitian ini bertujuan untuk mengetahui apakah ada hubungan antara sense of community dengan caregiver burden pada orang tua yang memiliki anak down syndrome. Populasi dalam penelitian ini adalah orang tua yang memiliki anak down syndrome. Sampel dalam penelitian ini berjumlah 142. Teknik pengambilan sampel dalam penelitian ini dilakukan dengan teknik purposive sampling. Instrumen yang digunakan dalam penelitian ini berupa skala caregiver burden yang terdiri dari 38 aitem (31 aitem valid dan 7 aitem tidak valid) dengan koefisien reliabilitas sebesar 0,873 dan skala sense of community yang terdiri dari 34 aitem (30 aitem valid dan 4 aitem tidak valid) dengan koefisien reliabilitas sebesar 0,915. Hasil perhitungan dibantu dengan software pengolah data, diperoleh sense of community berada pada kategori tinggi dan caregiver burden berada pada kategori rendah. Uji hipotesis dilakukan dengan formula korelasi Spearman menghasilkan nilai rho sebesar -0,473 dengan nilai signifikansi 0,000. Dengan demikian hipotesis yang berbunyi ada hubungan negatif antara antara sense of community dengan caregiver burden pada orang tua yang memiliki anak down syndrome diterima. Semakin tinggi sense of comunity, maka semakin rendah caregiver burden. Begitu juga sebaliknya, Semakin rendah sense of community, maka semakin tinggi caregiver burden.

Abstract

This study examined the effectiveness of combining Automated Writing Corrective Feedback (AWCF) and Teacher Written Corrective Feedback (TWCF) in improving students’ writing skills at SMK Bina Karya 2 Karanganyar. A mixed-methods approach was employed using an explanatory sequential design. Quantitative data from pre- and post-writing tests showed a significant improvement in mechanics, grammar, vocabulary, organization, and content of descriptive texts (t(58) = 8.888, p < .001). Qualitative findings from interviews and questionnaires indicated that students engaged with feedback in behavioral, cognitive, and affective dimensions. Low-proficiency students accepted most automated corrections, while advanced learners selectively applied feedback. AWCF was most effective for surface-level errors, while TWCF provided deeper support in content, coherence, and organization. A structured feedback process, where students revised based on automated corrections before receiving teacher guidance, ensured iterative improvement and minimized cognitive overload. The combination of AWCF and TWCF fostered self-regulated learning, reduced writing anxiety, and enhanced overall proficiency. Student perceptions varied; 78% found AWCF helpful for grammar, but only 42% believed it improved overall writing. Teachers noted that TWCF provided clearer explanations, reinforcing deeper learning. The integration of AWCF and TWCF enabled students to develop both linguistic accuracy and higher-order writing skills. These findings underscore the importance of a hybrid feedback model balancing efficiency, personalization, and engagement, ultimately enhancing students' writing proficiency in a structured and effective manner.

Abstract

Clean water is one of the targets in the Sustainable Development Goals (SDG's), specifically ensuring the availability and sustainability of water management. Continued use of groundwater results in land subsidence. The high level of rainfall in Jakarta requires rainwater to be utilized to reduce surface water runoff, especially by rainwater harvesting. PLN Institute of Technology has a total of more than 3.000 employees and students. Based on the use of non-domestic water needs in universities per day for universities of 10 liters/student/day. The volume of rainwater generated by the roof area of PLN Institute of Technology with an area of 1.024 m2 and the mainstay rainfall from 2012 to 2022 was obtained a total of 2.159,18 m3 per year. The storage tanks are made the size of each storage tank that can accommodate a volume of water of 300 m3 with a length of 15 meters, a width of 10 meters and a depth of 2 meters. By using the rainwater harvesting system at PLN Institute of Technology based on the calculation of the potential for meeting water needs, there is an excess of harvested rainwater of 1,202.78 m3 when the number of users is 10% and as much as 248.78 m3 when the number of users is 20% that can be accommodated for use.
