Abstract

Abstract: SDN Pacitan library already has a wide collection of books, good books related to school subjects as well as books that are not related to school subjects. However, the data processing on SDN Pacitan library is still using a conventional manner, ie, record data members, data books, data borrowers, data returns, and late return of books into a book-keeping. Library officials SDN Pacitan difficulties in data processing, such as when searching for data in the books of the borrower, other than that officer is also difficult to check the availability of the book, because it must be checked one by one in the bookcase. To determine the amount of fines officer must look at the number of days delay in returning and multiplying it with a fine every day. Students who would like to borrow or return any book takes a long time, because they have to wait for official records of books borrowed in the books. Students also have to wait long when it will return the book, because the officers had to find the borrower the data one by one in the books. When the amount of data borrowers have many officers find it very difficult and time required to search datapun be longer. The main purpose of this penelitin is making the information systems that can be used for data collection on the SDN Pacitan Library administration. The method taken by the authors observe, interview, library study, analysis, information system design followed by construction of information systems and the next is a trial. The results of this study is to provide ease of data processing libraries, such as data books, data books borrowers, data return the book, and to simplify the search process other than the data storage medium that has a more effective and larger. Keywords: Library Information System, Elementary School of the State Pacitan   Abstrak : Perpustakaan SDN Pacitan sudah memiliki berbagai koleksi buku, baik buku yang terkait dengan pelajaran sekolah maupun buku-buku yang tidak terkait dengan pelajaran sekolah. Akan tetapi proses pengolahan data pada perpustakaan SDN Pacitan saat ini masih menggunakan cara yang konvensional, yakni mencatat data anggota, data buku, data peminjam, data pengembalian, dan denda keterlambatan pengembalian buku  ke dalam sebuah pembukuan. Petugas Perpustakaan SDN Pacitan kesulitan dalam proses pengolahan data, seperti ketika mencari data peminjam dalam pembukuan, selain itu petugas juga kesulitan untuk mengetahui ketersediaan buku, karena harus mengecek satu-persatu dalam rak buku. Untuk mengetahui jumlah denda petugas harus melihat jumlah hari keterlambatan pengembalian dan mengalikannya dengan denda setiap hari. Siswa yang akan meminjam atau mengembalikan bukupun membutuhkan waktu yang cukup lama, karena harus menunggu petugas mencatat buku yang dipinjam dalam pembukuan. Siswa juga harus menunggu lama ketika akan mengembalikan buku, karena petugas harus mencari data peminjam satu-persatu dalam pembukuan. Ketika jumlah data peminjam sudah banyak petugas merasa sangat kesulitan dan waktu yang dibutuhkan untuk mencari datapun akan semakin lama. Tujuan utama dari penelitin ini adalah pembuatan sistem informasi yang dapat digunakan untuk pendataan administrasi Perpustakaan di SDN Pacitan. Metode yang diambil penulis yaitu dengan melakukan observasi, wawancara, study pustaka, analisis, perancangan sistem informasi dilanjutkan dengan pembangunan sistem informasi dan selanjutnya adalah uji coba. Hasil dari penelitian ini adalah untuk memberikan kemudahan dalam proses pengolahan data perpustakaan, seperti data buku, data peminjam buku, data pengembalian buku, dan untuk mempermudah dalam proses pencarian data selain itu memiliki media penyimpanan yang lebih efektif dan lebih besar.

Abstract

Indonesia is a potential country in developing essential oils which is each part of the plants produce essential oils such as leaf, seed, fruit, and root. One of the potential plants is fennel. Fennel oil distillation used fennel seed from Cepogo District, Boyolali Regency. The characteristics of the seed are; the color is black and the length is 0,2 centimeters. The condition operation to exctract of the fennel seed are 1 atm and 7,5 hours. The calculation of the time started when the first fennel oil dropped into the decanter. It finished when the fennel oil was not dropped anymore. The color is bright and muddy. The last process is add 1% (m/m) Na2SO4 anhidrous into fennel oil to absorp remain water in it. The distillation process produce fennel oil102,125 grams. Sample of fennel oil tested which are density test, solubility on 90% alcohol, GC-MS test, and AAS test. The result shows that fennel oil from the fennel seed is 2,0425%. The tested samples contain the brightest and the muddies sample. The density of 0,9500 and 0,949 g/cc respectively that is not fulfill to  the Food Chemical Codex (FCC). Samples solubility in 90% alcohol (1:3) is fulfill to the the Food Chemical Codex (FCC).  Three main components of the brightest sample are anethole (47,51%), estragole (22,41%), and  ?-fensone (21,92%) while the muddiest sample?s components are anethole (52,38%), estragole (21,37%),and ?-fensone (15,74%). The AAS test shows that fennel oil contains 65,1473 ppm which does not fulfill the Indonesian National Standards of  patchouli and clove leaf oil.

Abstract

Kencur (Kaempferia galanga L.) banyak digunakan sebagai bahan baku obat tradisional (jamu), fitofarmaka, industri kosmetika, industri makanan, dan industri insektisida. Minyak atsiri rimpang kencur mengandung etil sinnamat dan metil p-metoksi sinamat (EPMS). Ekstraksi oleoresin kencur dilakukan dengan etanol sebagai pelarut. Optimasi yield EPMS diteliti terhadap perbandingan massa serbuk kering kencur dan etanol dan waktu ekstraksi. Perbandingan kencur : etanol yang digunakan adalah 1 : 2, 1 : 3, dan 1 : 4. Waktu operasi yang digunakan adalah 2 s.d 5 jam. Tahapan proses ekstraksi oleoresin kencur adalah preparasi bahan, ekstraksi, evaporasi dan pemurnian. Oleoresin hasil ekstraksi dianalisis dengan uji GC-MS untuk mengetahui kandungan EPMS dan kandungan minyak atsiri lain dalam oleoresin kencur. Oleoresin hasil ekstraksi berwarna coklat tua dengan yield antara 6-8%. Kandungan EPMS dalam oleoresin bervariasi antara 67,77 hingga 87,57%. Massa oleoresin optimal hasil ekstraksi adalah 6,09 gram pada perbandingan kencur dan etanol 1:4 selama 4 jam. Pendekatan persamaan hasil ekperimen ekstraksi kencur dan etanol menghasilkan titik optimal EPMS pada waktu ekstraksi 3,62 dengan massa EPMS 6,04 gram Lesser galangal (Kaempferia galanga L.) is widely used as a traditional medicine (herbal medicine), fitofarmaka, cosmetics industry, food industry, and insecticide industry. The essential oils in the Lesser galangal contain ethyl sinnamat and methyl p-methoxy cinnamic (EPMS). The oleoresin extraction of Lesser galangal was performed using ethanol as a solvent. Optimization of the EPMS yield was investigated to dry powder mass ratio of Lesser galangal and ethanol as well as the extraction time. The ratio of Lesser galangal : ethanol was  varied from 1: 2, 1: 3 and 1: 4. The chosen operating time were 2 to 5 hours. The procedure of the oleoresin extraction process of Lesser galangal includes the preparation of materials, extraction, evaporation and purification. The extracted oleoresin was analyzed by GC-MS to determine the content of Ethyl P-methoxycinnamate (EPMS) and other volatile oil content in the oleoresin of Lesser galangal. The extracted oleoresin color was light brown to dark brown with the yield of between 6.31 to 8.3%. The EPMS content of the oleoresin varies between 67.77 to 87.57%. The optimum mass of the extracted oleoresin was 6.09 gram for 1:4 ratio of Lesser galangal : ethanol and 4 hours of the extraction time. The equation approach of the experimental results of Lesser galangal and ethanol produced the EPMS optimum point at the extraction time of 3.62 hours and EPMS mass of 6.04 grams.
