The reduction in the quantity of mangrove forest ecosystems will certainly have a negative impact on the balance of coastal ecosystems, people who live in coastal areas, and of course sustainable sustainable development proclaimed by the local government. The research objective is to analyze the damage of mangrove forest ecosystems through Environmental Science approach. One approach to the study in question is the remote sensing approach. The study was conducted throughout August 2018 precisely at Mampie Beach, Wonomulyo Subdistrict, Polewali Mandar District. The collection of mangrove forest vegetation data was conducted using purposive sampling (systematic plot) technique. The data used in the analysis of damage to mangrove forest ecosystems is the RBI Sheet Polewali Map Scale 1: 50000 BAKOSURTANAL in 1999, SPOT 4 Image in 2014, SPOT 4 Image in 2015, and Digital Globe Image Acquisition 6/9/2016. Data analysis and processing using the Arc-GIS program to analyze SPOT images, overlay and map making using Geographic Information System (GIS) applications, and descriptive analysis for the bio-physical data of mangrove vegetation. Data analysis of mangrove vegetation area in Mampie showed that overall from 1999 to 2016 the area of mangrove coverage experienced a shrinkage of 10.31 ha, namely 35.23 ha (1999) to 24.92 ha (2014). There is one thing that is quite encouraging that in the following year (2015) mangroves in the Mampie area expanded back to 0.58 ha ie to 25.50 ha but shrank back to 0.29 ha the following year (2016). Mampie Beach’s total mangrove area became 25.21 ha. The mangrove forest area in Mampie leaves only a few species of mangrove, the most dominating is Avicennia marina (Forsk.) Vierh.

The purpose of this service is that the community gains knowledge and skills in processing seaweed raw materials into quality noodle preparations and knowledge related to product marketing. The methods used are training methods for making seaweed flour, training for making seaweed noodles and training in product marketing. During the research, participants were very enthusiastic about participating in the series of programs implemented. Participants were very active in the discussion and many questions were asked. The result of this program is that the community has the understanding and skills in processing seaweed raw materials into quality noodle preparations as well as understanding related to product marketing so that participants gain comprehensive knowledge starting from making processed noodles to marketing activities. It is hoped that this program can be optimized by the community as a provision for improving the welfare of coastal communities. Keywords: marketing; noodles; processed; seaweed; tanjung mampie.

Indonesia is an archipelagic country, becoming one of the countries that have the largest area of mangrove forests in the world. Mangrove forests have a significant role, and its functions are perfect both directly and indirectly for the surrounding environment, especially for coastal residents, including preventing seawater intrusion, erosion, and coastal abrasion, as well as providing foodstuffs and becoming a nursery area for fish and invertebrates that live around it. However, mangrove forests throughout the world continue to experience pressure. The conversion of the function of mangrove forest land to other land uses to increase, for example, the conversion of mangrove forest land to ponds and residential areas, or the use of wood used as raw material for furniture and housing. In this case, human activities are considered to be the main cause of damage to mangrove forests. Therefore, it is essential to protect mangrove forests under pressure and rehabilitate mangrove forests that have been damaged. Budget limitations in the implementation of mangrove forest protection and rehabilitation programs cause the need to determine zones, which are work priorities in the implementation of the program. This study aims to determine the priority zones of work through the preparation of mangrove forest typologies based on the level of damage and the level of anthropogenic disruption in the area of forest designation through spatial analysis methods.

Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi pupuk conwy terhadap pertumbuhan rumput laut Gracilaria sp. yang dibudidayakan dalam skala laboratorium. Penelitian ini dilaksanakan di Laboratorium Multitrofik Pusat Kegiatan Penelitian Universitas Hasanuddin Makassar. Metode yang digunakan adalah metode eksperimental RAL (Rangkaian Acak Lengkap) 3 perlakuan dan 3 kali pengulangan, antara lain perlakuan PC1 (0,5 ml pupuk conwy); perlakuan PC2 (1 ml pupuk conwy); dan perlakuan PC3 (1,5 ml pupuk conwy). Parameter uji yang diamati pada penelitian ini yaitu pertumbuhan, pigmen dan kualitas air. Data yang diperoleh dianalisis dengan menggunakan analisis ragam (ANOVA). Data yang menunjukkan pengaruh yang nyata dilanjutkan dengan uji lanjut W-Tukey. Hasil yang diperoleh perlakuan PC 1 merupakan perlakuan yang memiliki pertumbuhan yang paling tinggi dengan rata-rata 13,41%, diikuti pada perlakuan PC 2 12.48% dan perlakuan yang terendah terjadi pada perlakuan ke PC 3 dengan pertumbuhan rata-rata 12.09%.
