Abstract

Ornamental fish is a type of fish that lives in both fresh and sea water which has attractive and beautiful body shapes or colors. One type of ornamental fish with its own uniqueness compared to other ornamental fish is Betta fish (B. splendens.). As an alternative, the test was carried out for a long time the male parent who cared for larvae at different times on the effect of survival of betta fish larvae on the type of plaque (B. splendens). The parent used in this study is a parent of 4 months old which is prepared as many as 1 pair / container of maintenance and in total there are 12 pairs. The research container used in this study was an aquarium with a water level of 10 cm, 12 pieces. Each container is labeled according to randomization and is equipped with aeration with a small pressure. The water used in this study is water originating from excavated wells. Before use water is first deposited to remove sedimentation. For the best treatment, the highest survival rate of betta (B. splendens) larvae was found in treatment A, which was 11.56%, followed by treatment B (8.44%), then treatment C (7.51%) and treatment D (4.81%). The highest absolute length growth is found in treatment D, which is equal to 14.33 mm, followed by treatment C (14.00 mm), then treatment B (12.83 mm) and treatment A (11.17 mm).Keywords: Plaque Betta Fish, Maintenance Length by Male Parent, Survival, Growth, Water Quality.AbstrakIkan hias merupakan jenis ikan yang hidup di air tawar maupun laut yang mempunyai bentuk atau warna tubuh menarik dan indah. Salah satu jenis ikan hias dengan keunikan tersendiri dibandingkan ikan hias lainnya adalah ikan cupang (B. splendens.). Sebagai alternatif uji yang dilakukan adalah lama induk jantan yang mengasuh larva dengan waktu yang berbeda terhadap pengaruh kelangsungan hidup larva ikan cupang jenis plakat (B.  splendens).Induk yang digunakan dalam penelitian ini adalah induk yang berumur 4 bulan yang di persiapkan sebanyak 1 pasang / wadah pemeliharaan dan secara total berjumlah 12 pasang.Wadah penelitian yang digunakan dalampenelitian ini adalah akuarium dengan ketinggian air 10 cm, sebanyak 12 buah. Masing-masing wadah diberi label sesuai dengan pengacakan dan dilengkapi aerasi dengan tekanan yang kecil. Air yang digunakan dalam penelitian ini adalah air yang berasal dari sumur galian. Sebelum digunakan air terlebih dahulu diendapkan untuk menghilangkan sedimentasi. Untuk perlakuan yang terbaik menunjukkan bahwa tingkat kelangsungan hidup larva ikan cupang (B. splendens) tertinggi terdapat pada perlakuan A yaitu sebesar 11,56% selanjutnya diikuti perlakuan B (8,44%), kemudian perlakuan C (7,51%) dan perlakuan  D (4,81%). Pertumbuhan panjang mutlak tertinggi terdapat pada perlakuan D yaitu sebesar 14,33 mm selanjutnya diikuti oleh perlakuan C (14,00 mm), kemudian perlakuan B (12,83 mm) dan perlakuan  A (11,17 mm).Kata Kunci :Ikan cupang Plakat, Lama Waktu Pemeliharaan Oleh Induk Jantan, Kelangsungan Hidup, Pertumbuhan, Kualitas air.

Abstract

Fluctuations that occur in the number of employees at PT Bank Syariah Mandiri Gunung Tua Sub-Branch Office, which indicates employee dissatisfaction. The fluctuation that occurred was caused by several employees who applied for resignation for several reasons as well as employee dismissal due to not achieving the target. The formulation of the problem in this study is whether the influence of work environment, competence, and career development has an influence on employee job satisfaction. The aim is to determine whether there is an influence of these three variables on employee job satisfaction at PT Bank Syariah Mandiri Gunung Tua Sub-Branch Office. This research is a quantitative study with sampling using saturated samples with a sample size of 17. The data collection technique uses literature study, interviews, documentation and questionnaires. Data analysis techniques include instrument test (validity test, reliability test), classic assumption test (normality test, multicollinearity test, heteroscedasticity test), multiple linear regression analysis, hypothesis testing (determination coefficient test (R2), t test, F test). To simplify the data analysis process, this research was assisted by the SPSS version 23 program. The results of the t test showed that there was no influence of the work environment on employee job satisfaction, there was no influence between competence on employee job satisfaction, and there was an influence between career development on employee job satisfaction. Simultaneously there is an influence between work environment, competence, and career development on employee job satisfaction.

Abstract

Concrete block is a building element made from a mixture of Portland cement or pozzolan, sand, water, and other additives. This study aims to evaluate the effect of adding palm shell ash as a partial cement substitution material on the compressive strength and water absorption of concrete block according to SNI 03-0349-1989. The variations of palm shell ash substitution used were 5%, 10%, 15%, and 20% of the cement weight. The test results showed that the average compressive strength values for the BN (normal), BA-5, BA-10, BA-15, and BA-20 variations were 8.88 MPa, 12.2 MPa, 7.9 MPa, 7.2 MPa, and 6.7 MPa, respectively. The optimum compressive strength value was achieved in the BA-5 variation with a value of 12.2 MPa and was included in the classification of quality I concrete block. A decrease in compressive strength occurred in variations above 5%, but still met quality standards I and II. The water absorption test showed consecutive values of 10%, 10.5%, 13.4%, 13.2%, and 15.3%, where all variations were still below the maximum limit of 25% according to SNI and categorized as quality I. Thus, palm shell ash has the potential to be a cement substitute in making bricks, especially at a content of 5%, which provides the best mechanical and physical performance.

Abstract

Kemacetan lalu lintas merupakan masalah yang biasa terjadi pada jam-jam antar dan jemput anak sekolah. Jumlah mobil yang berlebihan, infrastruktur jalan yang buruk, dan manajemen lalu lintas yang tidak memadai juga dapat berkontribusi pada keadaan ini. Tujuan dari penelitian ini adalah untuk mengetahui penyebab kemacetan lalu-lintas pada jam antar dan jemput sekolah di kawasan pendidikan. Sasaran atau lokasi penelitian pada Jalan Samudera Kota Lhokseumawe pada kawasan pendidikan. Volume lalu lintas pada jam antar jemput anak sekolah hasil yaitu jam puncak pada hari Senin pukul 07.00-08.00 dan pukul 13.00-14.00 WIB pada jalan Samudera dengan nilai sebesar 1.084 dan 1.415 skr/jam. Hasil analisa yang diperoleh bahwa kemacetan disebabkan karena adanya pedagang dibahu jalan dengan hambatan samping memiliki nilai tinggi yaitu pada jam 13.00-14.00 hasil total sebesar 550 dengan hambatan samping tinggi (H). Kinerja kemacetan dikawasan pendidikan pada derajat kejenuhan pada hari Senin pukul 07.00-08.00 dan pukul 13.00-14.00 WIB pada jam puncak derajat kejenuhan jalan Samudera dengan nilai sebesar 0,55 dan 0,72. Kemacetan lalu-lintas pada jam puncak antar dan jemput sekolah diperoleh hasil tinggi, pada jam tertentu pengalihan arus lalu lintas dimana kendaraan biasanya melalui 2 lajur dialihkan menjadi 1 jalur lalu lintas pada jam puncak antar jemput sekolah.
