Permintaan konsumen yang tidak menentu sering terjadi pada Toko Aqilah Herbal, hal tersebut menjadi masalah terhadap kontrol persediaan produk. Produk yang disediakan oleh toko sering mengalami kekuarangan atau kelebihan, hal ini menyebabkan kerugian atau komplain dari konsumen. Untuk mengatasi hal tersebut dan untuk memberikan perkiraan persediaan produk agar lebih tepat dan sesuai kebutuhan dengan melihat penjualan obat periode sebelumnya dan memperkirakan kondisi di periode berikutnya maka Toko Aqilah Herbal memerlukan suatu sistem yang dapat memprediksi jumlah persediaan obat herbal. Sistem tersebut pula bertujuan untuk menambah laba dan mengurangi resiko kerugian akibat berlebih maupun kurangnya persediaan jumlah obat herbal. Diagram Arus Data (DAD) dipilih untuk menunjukkan model sistem dan aliran data pada sistem. Adapun teknik peramalannya menggunakan metode Single Exponential Smoothing ialah sebuah teknik peramalan dengan perbandingan untuk mencari nilai alpha, dengan melacak nilai alpha tersebut secara random (trial) hingga memperoleh alpha yang mempunyai error paling kecil dengan pencarian memakai metode kesesuaian MSE (Mean Square Error). Ukuran atau alpha yang dipakai untuk memperkirakan persediaan obat herbal yaitu alpha = 0.1, alpha = 0.2, alpha = 0.3, alpha = 0.4, alpha = 0.5, alpha = 0.6, alpha = 0.7, alpha = 0.8, dan alpha = 0.9. dengan melacak nilai alpha secara random (trial) hingga diperoleh alpha yang mempunyai error terkecil. Maka hasil perkiraan yang mempunyai alpha dengan nilai error terkecil merupakan yang paling baik. Hasil penelitian ini berupa sebuah sistem informasi peramalan persediaan obat menggunakan metode Single Exponential Smoothing yang dapat dimanfaatkan untuk memperkirakan berapa banyak persediaan obat satu periode ke depan. Dengan menggunakan sistem ini, pemilik toko dapat dengan mudah menentukan jumlah pembelian obat untuk memaksimalkan persediaan obat. Kata kunci: Peramalan, Persediaan, Single Exponential Smoothing.
The Indonesian traditional local custom known as the Ulayat is a local community right to manage certain surrounded land or water for marine natural resources management. There is recognition that the existence of customary law in Indonesia, especially concerning the fisheries and marine resources management system, is of the important and strategic value of the national effort to support sustainable marine and fisheries resources management. The aims of this research are: to identify the perceptions and aspirations of society toward Local Custom values and the adherence to the prevailing traditional/customary law, and to identify the extent to which opportunities for Local Custom values empowerment can be preserved and utilized in managing the coastal areas in North Lombok. This research uses a case study method (Yin, 2011) and qualitative analysis method. The sampling method is being collected purposively. The research results showed that the perceptions and aspirations of society toward the Local Custom values (called awig-awig) is still very strong and is still being practiced. Society tends to be more convinced that the law enforcement using customary law is more effective and has a strong deterrent effect because there are clear sanctions and prohibitions. It is due in part to distrust of the formal law, which seems arbitrary in pursuing any prosecution. The Local Custom, tradition, and customary law, as well as traditional institutions in North Lombok Regency, have an opportunity to be preserved and further developed by implementing awig-awig.
The novelty of this research shows that addressing climate change in coastal areas not only strengthens public awareness of the dangers of sea level rise but also increases the integration of ecosystem services both in land and seascapes. Coastal areas at the global, national and local levels are experiencing severe degradation. The decline in the number of services provided by coastal ecosystems in Indonesia, such as mangroves, coral reefs, and seagrasses, is due to the intensification of anthropogenic processes. The impact is the increasing intensity of tsunami waves, tidal flooding, and subsidence. This study aimed to create an integrated model for managing biological and ecological restoration of the coastal ecosystem in the coastal area of Tamban in Malang District in the planning process and institutional aspects. The method used for spatial mapping of the Tamban coastal area was unmanned aircraft (UAV). Meanwhile, the Partial Least Square (PLS) was used to determine the public's perception of and response to climate change. To make the best decisions regarding the impacts of climate change, interpretative structural modeling (ISM) was used. The results showed that the local people should participate actively in the planning, monitoring and evaluation process to increase the benefit from coastal ecosystems both in landscape and seascape. The conclusion of this study shows that preventing the impact of climate change must include the community involvement and policy formulations to utilize and restore landscape and seascape ecosystem services.
This study utilized beruas laut plant (Scaevola taccada) as a research material. The purpose of this study was to determine the antioxidant activity of S. taccada crude extract, especially on leaves and fruit extract. The highest levels of protein was found in the Scaevola taccada leaf (8.806%), the highest fat was found in the leaf (1.822%), the highest water was found in leaf (11.376%), the highest ash content was found in the leaf (14,78%) and the highest carbohydrates content was found in fruit (82.52%). Phytochemical analysis detected flavonoids, tannins, and steroid in the (S. taccada). Antioxidant analysis obtained IC50 values of chloroform leaf extract was 0.1944, methanol leaf extract was 0.1034, chloroform fruit extract was 0.464, and IC50 values of methanol fruit extract was 0.653.
