Penelitian ini bertujuan untuk mengetahui perilaku menyimpang sosial pada kalang remaja di Kelurahan Akehuda. Penelitian ini menggunakan metode kualitatif dengan objek penelitian meliputi pimpinan kelurahan (Lurah), Tokoh Masyarakat, Ketua Pemuda, Guru, RT, Ibu/bapak pemilik rumah sewa (indekos). Data dikumpulkan melalui observasi, wawancara, dan dokumentasi. Data yang terkumpul kemudian direduksi, dan ditarik kesimpulan. Hasil penelitian menunjukkan bahwa perilaku penyimpangan sosial ialah bentuk tindakan yang bertentangan dengan nilai-nilai adat dan norma yang berlaku di masyarakat, seperti miras, tawuran, judi, dan narkoba. Adapun faktor penyebab terjadinya perilaku penyimpangan sosial yang di lakukan oleh para remaja di kelurahan Akehuda yaitu Faktor keluarga, pergaulan, lingkungan, dan pendidikan. Perilaku menyimpang ini telah membawa dampak negatif pada keluarga dan diri sendiri, seperti orang tua di mata masyarakat sangat buruk dan terhina. Dampak dalam diri sendiri pun sangat besar seperti gangguan psikologi dan bahkan ada yang mengalami cacat fisik.
Greasy grouper (Epinephelus tauvina) is one type of marine fish that has economic value and can be developed into a promising cultivation commodity. The purpose of this research is to find Types of parasites and prevalence rates of ectoparasite in Greasy grouper (Epinephelus tauvina) on floating net cages in Kuala Langsa. The research method was conducted using a survey method. Sample taken by purposive sampling, amounting to 20 Greasy grouper (Epinephelus tauvina) with a size of 20-25cm and were observed at Laboratory Faculty of Agriculture, Samudra University. Fish body organs were observed including all parts of the fins, mucus, gills, then identification using microscopic and macroscopic methods. The results obtained were ectoparasites infecting Greasy grouper (Epinephelus tauvina) only one species from the genus Dactylogyrus which was found mostly in floating net cages cultivation in Kuala Langsa. These ectoparasite were found in the gill lamella Greasy grouper (Epinephelus tauvina), with the overall sample prevalence rate at 50% and the attack rate classified as “very frequent”.
AbstrakPenelitian ini bertujuan untuk mengetahui tingkat pertumbuhan ikan bawal yang diberi perlakuan cahaya pada malam hari. Metode yang digunakan pada penelitian ini adalah metode eksperimental dengan 4 perlakuan dan 3 ulangan. Pada setiap perlakuan dengan waktu pencahayaan selama P1=12 jam, P2=16 jam, P3=20 jam, dan P4=24 jam. Hasil dari perlakuan tersebut berpengaruh nyata terhadap laju pertumbuhan, bobot mutlak, panjang mutlak, dan rasio konversi pakan (FCR). Sedangkan pada sintasan tidak memiliki perbedaan yang signifikan. Laju pertumbuhan harian tertinggi terdapat pada P4 sebesar 5,30%, sedangkan laju pertumbuhan yang terendah terdapat pada P1 sebesar 4,47%. Berat mutlak tertinggi didapat pada P4 sebesar 25,40 gr, sedangkan berat mutlak terendah pada P1 sebesar 17,91 gr. Selanjutnya pada parameter panjang mutlak yang tertinggi juga pada P4 sebesar 4,66 cm, sedangkan yang terendah pada perlakuan P1 sebesar 3,66 cm. Pada rasio konversi pakan memiliki nilai tertinggi pada P1 sebesar 1,69±0,02 dan terendah pada P2 sebesar 1,45±0,12. Dari hasil perekayasaan dengan waktu pencahayaan pada lingkungan budidaya, semakin lama waktu pencahayaan yang diberikan maka pertumbuhan yang dihasilkan memiliki kategori semakin baik.Kata kunci: ikan bawal; lampu pijar; pertumbuhan; rekayasa cahayaAbstractThis study aims to determine the growth rate of pomfret, which is treated with light at night. The method used in this study is an experimental method with 4 treatments and 3 replications. At each treatment with lighting times for P1 = 12 hours, P2 = 16 hours, P3 = 20 hours, and P4 = 24 hours. The results of these treatments significantly influence the growth rate, absolute weight, absolute length, and feed conversion ratio (FCR), whereas the survival does not have a significant difference. The highest daily growth rate is in P4 of 5.30%, while the lowest growth rate is at P1 of 4.47%. The highest total weight in P4 of 25,40 gr, while the lowest total weight at P1 is 17.91 gr. Furthermore, the highest absolute parameter is P4 of 4.66 cm, while the lowest in the first step is 3.66 cm. The feed conversion ratio has the highest value at P1 at 1.69 ± 0.02 and the lowest at P2 at 1.45 ± 0.12. From the results of engineering with the lighting time in the aquaculture environment, the longer the lighting time is given, the better the resulting growth has been.Keywords: pomfret; incandescent bulbs; growth; light modification
IndiHome (Indonesia Digital Home) is a leading digital fibre optic service product consisting of fibre optic internet services, landline telephones, and interactive TV services. Although the coverage of Indihome products is extensive in the city of Medan, in marketing, Indihome products have not reached the planned target. Based on data from Indihome service package users that have been received, Indihome product users only numbered 6419 customers in all STOs in Medan City. At the same time, the target was planned by PT. Telkom Access Medan, namely Marketing Indihome products, must reach 5,000 customers per month in all STOs in Medan City. Indihome product marketing is an obstacle for PT. Telkom Access Medan, because the Indihome product is a new product, the people of Medan City do not fully know what Indihome is and what facilities they get from using the Indihome service package. Therefore PT. Telkom Access Medan needs to make a plan to make a marketing strategy. The first step that needs to be done is to segment the market for the Indihome service package. This study aimed to determine the application of Data Mining using the K-Medoids Clustering method in the Indihome service package market segmentation at PT. Telkom Access Medan. With this research, it is hoped that it can provide a reference for the results of the decision so that it can help related parties to make it easier to classify the market segmentation of the Indihome service package at PT. Telkom Access Medan. Because the value of S > 0, then the calculation is stopped and ends in the 3rd iteration. Indihome service package data processing uses the k-medoids clustering method in the form of potential, potential, and not potential STO (Sentral Telephone Automated) cluster members.
