Abstract

Furniture production made from mahogany wood produces sawdust that contains biomass such as cellulose, hemicellulose, and lignin. The lignin content in mahogany wood can be used as raw material for making sodium lignosulfonate surfactants. Delignification of lignin is carried out alkaline and continued with lignin isolation by acid precipitation. Pure lignin isolate is further used as a raw material for making sodium lignosulfonate surfactants using the sulfonation process. The sulfonation process is carried out by mixing lignin isolate and sodium bisulfite solution using excess NaHSO3 variation and sulfonation time. Both variables are run by adding sodium hydroxide as a catalyst and the pH condition was maintained at pH 4. The sodium lignosulfonate surfactant solution formed was then characterized using FT-IR spectrophotometer and UV-Vis spectrophotometer. The best condition was obtained at a sulfonation time of 150 minutes and NaHSO3 exceeded 75%, namely with a surfactant concentration of   4100,784 mg/L.

Abstract

ABSTRACT Language acquisition is a process that occurs when a child acquires his first language or mother tongue. The words spoken by a child can be calculated by the mean length of utterance (MLU). Through MLU the morpheme number is divided by the speech number. After the MLU calculation, the child's language development will be known. The purpose of this study was to determine the development of the first language of children aged 3 years 9 months based on their MLU measurements. The research method used in this study is a descriptive method with a qualitative approach. The data source in this study was a boy aged 3 years 9 months named Akmar Muhammad. The language used daily by Akmar Muhammad is Sundanese. Data was taken using a recording device. The results of the analysis prove that Akmar Muhammad at the age of 3 years 9 months is still lacking in language skills. Akmar should have been in stage IX (3.5-3.45) at the age of 41-46 months. However, the results of the MLU calculation are at stage IV MLU (2.25-2.5) at the age of 28-30 months. There are some imperfect pronunciation of phonemes such as /r/ becomes /l/ sometimes /r/ becomes /y/. There is a phoneme that is missing when pronounced [kepa] which should be [kelapa]. Keywords: Language acquisition, Average Length of Speech, Phonology ABSTRAK Pemerolehan bahasa merupakan proses yang terjadi pada seorang anak ketika memperoleh bahasa pertama atau bahasa ibunya. Kata-kata yang diucapkan seorang anak bisa dihitung dengan panjang rata-rata ujaran atau mean length of utterance (MLU). Melalui MLU bilangan morfem dibagi dengan bilangan ujaran. Setelah perhitungan MLU akan diketahui perkembangan bahasa anak tersebut. Tujuan penelitian ini untuk mengetahui perkembangan bahasa pertama anak usia 3 tahun 9 bulan berdasarkan pengukuran MLU-nya. Metode penelitian yang digunakan dalam penelitian ini adalah metode deskriptif dengan pendekatan kualitatif. Sumber data dalam penelitian ini adalah seorang anak laki-laki berusia 3 tahun 9 bulan bernama Akmar Muhammad. Bahasa yang digunakan sehari-hari oleh Akmar Muhammad adalah bahasa Sunda. Data diambil dengan menggunakan alat rekam. Hasil analisis membuktikan bahwa Akmar Muhammad di usia 3 tahun 9 bulan masih kurang dalam kemampuan berbahasa. Seharusnya Akmar berada pada tahap IX (3,5-3,45) pada usia 41-46 bulan. Namun, hasil penghitungan MLU berada pada tahap IV MLU (2,25-2,5) pada usia 28-30 bulan. Terdapat beberapa pengucapan fonem yang belum sempurna seperti /r/ menjadi /l/ terkadang /r/ menjadi /y/. Terdapat fonem yang hilang ketika diucapkan [kepa] yang seharusnya [kelapa].

Abstract

Mosques are one of the places where community activities are concentrated in the religious field, especially in Indonesia where the majority of the population is Moslems. The mosques are also important means of spreading religion, due to the close location and spread out in the community. The arrangement of the sound system in a mosque is one of the vital things to support religious activities. The purpose of this activity is to provide training on the installation and arrangement of sound systems at the Darul Muttaqin Mosque, Kedungkandang District, Malang. Training is given to mosque takmirs so that they can install and maintain sound systems in mosques. The result of this training was that the sound system of the mosque which was initially bad due to a buzzing sound and did not clearly convey the information provided became clearer and no longer disturbed the congregation or local residents. When there is a sound system problem, takmir can repair it directly without the need to wait for a technician so that religious activities and messages run smoothly.

Abstract

This study aims to obtain objective data regarding the role of Islamic Religious Education (PAI) teachers in instilling the habit of congregational prayer at MIN 11 Banda Aceh. The main focus of this research is to examine how Islamic religious education is implemented at the school and to what extent teachers contribute to developing the habit of congregational prayer among students.  The research employs an inductive qualitative method, with data collected through observations, interviews, document analysis, and questionnaires. The findings indicate that Islamic religious education at MIN 11 Banda Aceh has been implemented under the established curriculum. Its implementation includes the foundations of Islamic religious education, learning objectives, and teaching strategies designed to foster students’ religious character.  In efforts to instill the habit of congregational prayer, PAI teachers play three main roles: as trainers, role models, and disciplinarians. Among these roles, only two have been effective—serving as trainers and role models. Meanwhile, the disciplinarian role has been less successful, as students are not subjected to sanctions for failing to perform congregational prayers. Nevertheless, the school has established a rule that when the zuhr adhan is called, all teaching and learning activities must be paused to allow students to perform congregational prayers.

Abstract

Background: Anxiety is an excessive and unclear feeling of worry, and it is also a response to both external and internal stimuli that causes emotional, cognitive, physical, and behavioral symptoms. Anxiety is different from fear because, in fear, the object is clearly known and threatens the well-being of the person, while in anxiety, the object is unknown. Anxiety is an experience that everyone goes through (universal) throughout their life. Anxiety has a positive function because it can motivate people to take actions that can resolve their issues. Anxiety is considered normal when it is proportionate to the situation and will disappear once the situation is resolved. Objective: To determine the effect of the deep breathing relaxation technique on anxiety levels in pre-operative patients at the hospital. Methods: This study uses a pre-experimental design, quantitative correlation, with primary data from pre-operative patients aged 17-50 years, consisting of 126 respondents. Sampling was calculated using Slovin's formula. Data collection was done using a questionnaire and interviews with the Hamilton Anxiety Rating Scale (HARS). Results: From the 126 respondents, 14 (11.1%) had no anxiety, 51 (40.5%) had mild anxiety, 58 (46.0%) had moderate anxiety, and 3 (2.4%) had severe anxiety. The Chi-square statistical test showed a p-value of 0.000 (p <0.05), indicating that there is an effect of the deep breathing relaxation technique on anxiety levels in pre-operative patients at the hospital. Conclusion: There is an effect of the deep breathing relaxation technique on anxiety levels in pre-operative patients at the hospital (p=0.000).
