Abstract

Every child has different potential, interests and talents. Special gifted children whose potential is optimized and properly stimulated can become one of the quality human resources owned by the country, compared to children who do not get proper stimulation. Stimulation is a variety of stimuli, such as play opportunities, learning facilities, or materials (eg stories or reading), that can trigger a child to learn or process teaching. Optimal is the highest condition in which it is possible for someone or something to do without destroying the elements that are in place. Potential are specific things that exist in children, which appear more when compared to children of their age. Interest is a strong urge for someone to do everything he wants. Whereas talent is a basic trait, intelligence and innate nature that is innate. Talent itself can be interpreted as a person's basic ability to learn in a relatively short time compared to other people, but the results are even better. In short, this is a potential possessed by a person as innate. The aim of the research is to optimize the potential, interests and talents of the children in Lalalang Village for the advancement of potential human resources in the future, namely to find out and make solutions so that the children of Lalalang Village get a direction and a place to shape their character so that they are able to understand what potential they have and are very important for the future. This research contains the reasons and the process of optimizing the potential, interests and talents of the children in Lalang Village. Keywords: Optimization, Potential, Interest, Talent, Children

Abstract

The most dominant hospital activity actors at risk of occupational safety accidents (SMK3) are hospital employees such as nurses, cleaning services, patients and visitors. The purpose of this study was to evaluate the application and factors affecting the implementation of occupational health and environmental safety management systems at dr. Zainal Abidin Regional General Hospital, Meuraxa Hospital and Banda Aceh Mother and Child Hospital. The data collection technique uses a mix method that combines quantitative and qualitative data with sequential explanatory strategies. The legal basis is Permenkes No. 66 of 2016, and the data was analyzed using the Likert scale method points 1-5 through SPSS version 26. The results of research at RSUDZA, RSIA, and RSUDM Banda Aceh show that the application of SMK3 is good to very good. However, there are several inhibiting factors that need to be considered by the hospital in order to improve the implementation of the Occupational Safety and Health Management System (SMK3) at RSUDZA, RSIA, and RSUDM Banda Aceh, some improvements can be recommended. First, RSUDZA needs to ensure the stability of K3 field officers and improve the marking of K3 signs. In addition, the unification of the drug room with pharmacy employees must be separated to be more effective. RSIA needs to obtain budget for ceiling repairs so as to block various small dirt falling from roof gaps, avoid splashing rainwater falling through the roof insulators or regulators of heat and cold coming from the roof, roof frame covers to make the space neater and cleaner, sound dampers, both generated by rainwater and other sounds and rearrange the right material placement. RSUDM needs to overcome solid waste piles, improve the marking of K3 rooms, and improve the arrangement of parking areas. In addition, it is important to hire additional security personnel in the ER. All these improvements are expected to improve occupational safety and health conditions in hospitals.

Abstract

Total kapasitas produksi seluruh PKS yang beroperasi di Provinsi Aceh mencapai 770 Tons Tandan Buah Segar (TBS) per jam. Limbah dari produksi pabrik kelapa sawit biasa disebut Limbah Cair Pabrik Kelapa Sawit (LCPKS). Jika produksi limbah cair pabrik kelapa sawit berkisar 0.50-0.65 m3 per ton TBS, maka total limbah mencapai 2,471,814 m3 per tahun. LCPSK berpotensi dimanfaatkan melalui pengolahan biokonversi anaerobik secara termofilik untuk memperoleh biogas yang dapat dimanfaatkan sebagai energi. Sampel limbah cair yang digunakan pada penelitian ini diperoleh dari PKS Cot Girek PTPN I Aceh. Dalam penelitian ini, telah dirancang peralatan utama penelitian berupa digester dengan kapasitas 20 liter. Alat tersebut akan disisi dengan campuran LCPKS yang ditambahkan dengan kotoran sapi pada perbandingan 90%:10%, 80%:20%, dan 70%:30%. Kotoran sapi terlebih dahulu dicampur dengan limbah cair biogas untuk menghasilkan aktivator. Bahan baku masukan biogas didapat dengan mencampurkan LCPKS, aktivator, dan CaCO3 yang digunakan untuk meningkatkan pH, kemudian campuran dimasukkan ke dalam digester. Variabel penting yang diukur antara lain: suhu, pH, Nilai Volatile Solid, Kandungan Nitrogen dan Kandungan Karbon dan laju aliran produksi gas. Analisis dilakukan secara diskriptif. Produksi gas dianalisis dengan Analisis Regresi Linier, yang terdiri atas dua peubah, yaitu waktu perbandingan campuran LCPKS- kotoran sapi termasuk dalam peubah bebas, sedangkan produksi gas termasuk dalam peubah tak bebas. Dari hasil penelitian ini diharapkan akan dihasilkan satu prototipe digester anaerobik untuk produksi biogas dengan memanfaatkan limbah cair pabrik kelapa sawit.

Abstract

Green coconut shell and husk (GCSH) waste had the potential to pollute the environment if not properly utilized. As a solution, innovations in processing GCSH into biobriquettes could generate eco-friendly renewable energy with economic value. This study aimed to optimize the utilization of GCSH as a raw material for biobriquettes by adding jatropha seeds as an adhesive, as well as evaluating the characteristics of the produced biobriquettes. Fabrication of biobriquette was carried out using two methods: conventionally (without burning) and by pyrolysis (with burning) at temperatures of 380C, 430C, and 480C for 3.5 hours. The charcoal obtained from pyrolysis was mixed with jatropha seed adhesive at concentrations of 15%, 20%, and 25%, then molded at a pressure of 110 kg/cm and dried at 105C. The results showed that pyrolysis temperature and adhesive concentration affected the moisture content, ash content, calorific value, compressive strength, and combustion rate of the biobriquettes. Optimum conditions were achieved at a pyrolysis temperature of 430C with the addition of 25% adhesive, resulting in biobriquettes with high calorific value (6367.74 cal/g), low moisture content (7.44%), and good combustion rate (0.10219 g/min). This study proved that utilizing GCSH waste and jatropha seeds for biobriquettes had great potential as an efficient and sustainable source of renewable energy.

Abstract

The increase in carbon emissions resulting from industrial activities has become a major concern for environmental and climate conditions. Carbon Capture and Storage (CCS) represents a significant effort to mitigate the CO2 problem. Aceh Province possesses a potential distribution of serpentine, which may serve as an effective material for CCS applications. This study evaluates the effects of gas flow rate, particle size, sorbent weight, and pressure on CO2 adsorption using chemically activated serpentine. The activation process involved hydrochloric acid (HCl) at three concentrations: 8%, 9%, and 10%, with particle sizes of 50 mesh, 100 mesh, and 150 mesh. Activation was conducted at room temperature with an acid-to-serpentine ratio of 10:1 for 30 minutes. Adsorption tests were performed at ambient temperature under pressures of 2, 3, and 4 bar, with adsorption times of 30, 60, and 120 minutes. Results indicate that activated serpentine treated with 9% HCl and a particle size of 150 mesh achieved the highest performance, demonstrating an adsorption efficiency of 33.01% and an adsorption capacity of 82.22% (0.0488 g CO2/g adsorbent) at a pressure of 2 bar. Both the Langmuir and Freundlich isotherm models closely fit the data (R = 1). This study concludes that HCl activation significantly enhances the capacity and efficiency of serpentine as a CO2 adsorbent.

Abstract

In Indonesia, students and teachers often engage in disciplinary behaviour. Discipline is the only educational characteristic that needs to be emphasized in schools. Most students have not shown good disciplinary character, where students are not on time to enter class during study hours, like to skip class during learning, and do not do assignments so the character of poor student discipline becomes a habit. This study aims to determine the role of the guidance and counselling teacher in the formation of the disciplinary character of students at MTS Al Washliyah. The research method used in this study is descriptive qualitative which examines the role of guidance and counseling teachers in the formation of students' disciplinary character. The data were collected through interviews, document analysis, focused discussions, and observations as outlined in field notes. The results of this study indicate that the role of the guidance and counselling teacher in the formation of the disciplinary character of students is going quite well. Guidance and counselling teachers collaborate with student representatives, homeroom teachers, and parents to solve the problems of students who lack discipline. Students who lack discipline are given individual counselling services and guidance and counselling teachers also make visits to students' homes to find out the factors causing these students to lack discipline and to discuss student problems at school with students' parents. The findings of this study are the role of guidance and counselling teachers in shaping the disciplinary character of students in MTS Al Washliyah.

Abstract

Mercury is harmful to humans and the ecological environment. The adsorption process is known as an effective method for removing heavy metals. This research is devoted to developing new adsorbents based on carbon materials to remove metal ions Hg(II) with carbon-based monolith adsorbents without and with manganese oxide fillers (KM and KMM). The results of adsorption efficiency, adsorption kinetics, and isotherm models were made in a batch system with varying concentrations of mercury solution from 2 mg/L to 6 mg/L with adsorbents without and with manganese oxide fillers (KM and KMM). The highest removal efficiency reached 96% on KMM and 47% on KM. The adsorption isotherm of Hg(II) ions corresponds to the Freundlich model, with intensity and volume constants obtained respectively 0.042 and 1.347 L/mg on KM adsorbents, while on KMM adsorbents the intensity and volume constants obtained are 0.291 and 2.079, respectively. L/mg. These results indicate that physical adsorption occurs more dominantly than chemical adsorption. The adsorption of Hg(II) ions was in accordance with the pseudo-first-order adsorption kinetics, with the adsorption capacity and rate constant on the KM adsorbent obtained were 0.0505 mg/g and 0.0072 g/mg, while the adsorption capacity and rate constant for the KMM adsorbent were on KM adsorbents obtained were 0.0848 mg/g and 0.0239 g/mg.

Abstract

Pemanfaatan batubara sebagai sumber energi melalui pembakaran langsung akan menghasilkan emisi gas, partikulat trace metal (logam berat) dan abu (terutama abu terbang) yang akan mencemari udara. Penanganan terhadap pencemaran tersebut merupakan hal yang sangat mendesak. Dalam studi ini ditawarkan penyelesaian secara simultan terhadap emisi SOx dan partikulat logam berat merkuri pada pembakaran batubara peringkat rendah yang ada di Aceh melalui penyerapan menggunakan bentonit alam yang juga terdapat di Aceh (juga di daerah lain di Indonesia). Penggunaan bentonit dapat mengurangi emisi gas SO2 dan partikulat trace metal Hg dalam gas buang dan abu terbang. Bentonit dapat meningkatkan afinitas atau gaya tarik menarik antara Hg dan mineral-mineral dalam bentonit dan sekaligus menurunkan afinitas Hg terhadap S atau SO2. Konsentrasi bentonit dalam kajian ini, tanpa kalsinasi dan langsung dicampur dalam batubara, adalah 0 16% dan temperatur pembakaran adalah 700 900oC. Hasil yang didapat menunjukkan bahwa kondisi maksimum penyerapan sulfur dan/atau SO2 serta merkuri terjadi pada kandungan bentonit 6% dan temperatur 700oC.

Abstract

Pembakaran biomassa dalam rangka memproduksi energi termal untuk menghasilkan utilitas lain dapat dilakukan dengan mengkonversi energi tersebut ke bentuk energi lain. Boiler dengan unggun terfluidisasi dipilih sebagai teknologi konversi energi termal menjadi energi listrik, karena kukus yang diproduksi dapat digunakan untuk menggerakkan turbin yang dikopling dengan generator listrik. Unit dimana proses pembakaran berlangsung, yaitu ruang bakar dan freeboard dipilih sebagai target pengamatan untuk mengevaluasi kinerja boiler tersebut. Hasil pengamatan terhadap pembakaran tiga jenis biomassa, serpihan kayu ketam, kulit pinang dan ranting kayu kering, memperlihatkan bahwa masing-masing jenis biomassa memiliki karakteristik pembakaran tersendiri. Temperatur pembakaran maksimum untuk serpihan kayu ketam dan ranting kayu kering didapatkan pada waktu pembakaran 30 detik, sementara untuk kulit pinang pada 20 detik. Hasil yang sangat menarik adalah ditemukan bahwa temperatur maksimum dapat ditingkatkan dengan mengubah sistem pengumpan bahan bakar. Sistem pengumpan antara memberikan temperatur maksimum yang lebih tinggi dibanding dengan sistem pengumpan biasa.
