INTISARIKerahasiaan data sangat diperlukan untuk menjaga dari pihak=pihak yang tidak berwenang agar tidak dapat mengaksesnya, untuk itu diperlukan teknik steganografi dan enkripsi untuk mengaburkan pesan yang dikirimkan ke dalam bentuk gambar / cover image. Tujuan utama penelitian ini adalah membuat aplikasi yang berguna memasukan teks / plain text yang akan dienkripsi menggunakan kata kunci / encryption key menjadi cypher text kemudian disisipkan ke dalam cover image menjadi stego object kemudian hasil dari stego object dipisahkan antara cypher text dan cover image, selanjutnya cypher text didekrip menggunakan kata kunci / encryption key untuk dapat menghasilkan teks sumber / plain text. Metode yang digunakan dalam penelitian ini adalah algoritma transposisi columnar dengan model transposisi 12-21. Hasil yang diperoleh dari penelitian ini membandingkan ukuran file dari gambar yang menjadi cover image, stego object, dan gambar hasil dari pemisahan cypher text dari stego object. Kesimpulan yang diperoleh ukuran file antara cover image dan stego object tidak mengalami perubahan yang signifikan berapapun jumlah ukuran teks yang disisipkan / hidden text ke cover image sehingga kriteria Steganografi yakni Fidelity, Robustness, dan Recovery terpenuhi dengan baik.Kata kunci ? kriptografi, steganografi, cover image, Stego object, plain text, cypher text, encryption key dan transposisi columnar. ABSTRACTThe confidentiality of data is very necessary to protect the party from unauthorized parties so that they cannot access it, for this reason steganography and encryption techniques are needed to obscure the messages sent to them in the form of images. The main purpose of this research is to make an application that is useful to enter text / plain text that will be encrypted using the encryption key to be a cypher text and then inserted into the cover image into a stego object then the results of the stego object are separated between the Cypher text and cover image, then cypher Text is decrypted using an encryption key to produce plain text. The method used in this study is the columnar transposition algorithm with the transposition model 12-21. The results obtained from this study compare the file size of the image that is the cover image, stego object, and the image resulting from the separation of the cypher text from stego object. The conclusions obtained by the file size between the cover image and stego object did not change significantly regardless of the number of sizes of text inserted / hidden text to the cover image so that the Steganography criteria, namely Fidelity, Robustness, and Recovery were fulfilled well.Keywords - cryptography, steganography, cover image, Stego object, plain text, cypher text, encryption key and columnar transposition.

Tanjung Lalak Health Center is located at Education street RT 1. TanjungLalak Selatan Village, Pulau Laut Kepulauan District, Kotabaru Regency. South Kalimantan. Tanjung Lalak Health Center has several poly services including: Pregnant/Obsig poly. Some of the services provided by the puskesmas for pregnant women who check themselves include obtaining the MCH book (Maternal and Child Health), a pink book that mothers must have.

The midwife will check blood pressure, measure arm circumference, and examine the condition of the pregnant woman's stomach. At the Tanjung Lalak Health Center there are no ultrasound facilities, so if you want to confirm the condition of the fetus, you have to visit an obstetrician or regional hospital. Of course this costs money because BPJS is not covered for USG except for emergency situations. The puskesmas midwife will provide free vitamins or supplements such as folic acid, calcium, and iron supplement tablets to support the growth of the fetus in the womb. In addition to vitamins, pregnant women get additional food in the form of biscuits with strawberry-flavored cream. The puskesmas will provide several cartons of biscuits for a few weeks' supply. These biscuits are consumed 2 to 3 pieces per day. The Tanjung Lalak Health Center requires blood tests for pregnant women. These tests include a blood test and checking sugar levels at least twice during pregnancy and are free of charge. The problem that will be discussed in this study is to record the history of examination of pregnant women and record supplies of vitamins/supplements, biscuits for pregnant women and medicines that are available for the Pregnant/Obsigin Polyclinic. The application will be made using database access with Visual Basic .net, the final conclusion of the application is that it can store data from midwives' examinations on pregnant women and print Maternal and Child Health Books, the application can print reports on the activities of the Pregnant Poly / Obstetrician Polyclinic every month as a general report every month to the Head of the Tanjung Lalak Health Center, as well as the application to automatically record the remaining supplies of vitamins, biscuits and medicines, and make it easier for the Tanjung Lalak Health Center Midwives to see the history of examinations of pregnant women and the administration of medicines, vitamins and biscuits.

The business of selling medicines and herbal supplements at Farah Shop was pioneered in mid-2017 by Farah Putriana as the official distributor for several brands such as HDI, DXN, Herbalife, and so on. Products sold include cough medicine, slimming medicine, honey, and so on. Farah's shop is located at Jalan Sultan Adam, Taekwondo complex Permai line III no. 7 Surgi Mufti Village, North Banjarmasin with telephone number 081254545594. The management of recording the purchase and sale of drugs and herbal supplements uses a semi-computer system by recording on a spreadsheet application, some business problems at Farah's shop such as the slow preparation of profit reports from the sale of medicinal and herbal supplement products, difficulties in obtaining final inventory reports of medicinal and herbal supplements, marketing of medicinal and herbal supplement products is still limited because prospective buyers must come in person or ask product questions to the admin using the Whatsup application, with With the rapid development of the internet at this time, the owner of Farah Shop considers it necessary to make better use of this technology by creating an online application where prospective buyers can view and choose the medicine or herbal supplement that they will buy directly. This will increase sales from the Farah Shop business. Another problem is that making reports on the total sales and purchases of medicines and herbal supplements which are carried out every month is constrained by time and effort due to the absence of a good computer system. Difficulties in seeing the final stock of drugs or supplements so that orders from buyers are often not fulfilled, research will make applications using MySQL and PHP databases with a general description of providing online sales services, which can serve buyers who come directly to Farah's shop or who will buy directly via the internet online. The application made can store buying and selling data of drugs and herbal supplements in the database. The application can quickly generate reports on the remaining stock of medicines and herbal supplements, as well as generate reports on the purchase and sale of medicines and herbal supplements at the Farah Banjarmasin Shop which can be viewed daily, weekly and monthly
