Abstract

Aquatic Tourism Park (ATP) of the Southeast Sulawesi Province has significant contribution to achieve the total targeted of 30 million of Marine Protected Areas (MPA) in Indonesia. The conservation area is located in 3 coastal districts of Konawe, South Konawe, and Kendari City Districts. The time-consuming process of legalizing the conservation area has driven the need to re-evaluate the ecological conditions from 2012 to 2020. The objective of this study is to this aims to determine the status, gaps and ecological feasibility of conservation areas in the Southeast Sulawesi region. One of the noticeable gaps is the change of ecological conditions in the reservation area. The gap could be identified by comparing ecological conditions before and after the area was reserved for a conservation area. Ecosystem suitability was measured by using ecological criteria, such as number of protected fish species, mangrove density, seagrass coverage, coral coverage, and naturalness. The score of suitability assessment was 31, which showed that the reserved location was suitable for a Marine Conservation Area. However, gap analysis results showed 10% decline in coral coverage and 17% decrease in seagrass coverage, while mangrove density decreased as much as 102 trees/ha during that period. Evaluation on the ecosystem condition was conducted by applying suitability analysis of the modified E-KKP3K dan Sambah et al. (2020) methods, resulting a status of suitable or conservation area allocation (score 31). Criteria used were chosen based on its contribution in facilitating important ecological processes and as ecosystem buffer system in the area. This study will give the implementation on MPA management optimalisation and it can be contributed on fisheries management.Keywords:Conservation areaFeasibility areaGapSoutheast Sulawesi

Abstract

The COVID-19 pandemic has suddenly forced the world of education to carry out a more massive digital transformation that should meet student’s requirements and strengthen their knowledge, skills and competencies. The digital media developed should facilitate student’s self-learning and freedom to learn (Merdeka Belajar) amidst physical and social interaction limitations. Vocational high school students have special requirements compared to upper secondary school students in terms of soft skills and hard skills education. It is very interesting to provide digital educational media which fits their needs. This study aims to develop an online digital platform in responding to the demand of vocational schools that have joined the SEAMEO BIOTROP SMARTS-BE program since 2015 in applied tropical biology. Since 2015, SEAMEO BIOTROP has provided face-to-face mentoring to vocational high schools spread across 10 provinces in Indonesia. The Expert System for Identifying Pest and Disease on lemon orchard is a digital transformation in the mentoring method while demonstrating a new learning experience educational materials into a web-based digital platform and Android application. This expert system demonstrates the implementation of problem base learning (ProBL) concepts to enrich online learning materials for vocational schools in the age of digital science and education.

Abstract

Seagrass ecosystems offer valuable ecosystem services but are highly vulnerable to physical damage caused by human activities and rapid environmental change. Currently, there is very limited information available on monitoring and reporting the health of seagrass beds in Indonesian waters. This study aims to assess the species composition, density, diversity index, percentage of seagrass cover, health condition, and identification of threats to seagrass ecosystems around the West Likupang Special Economic Zone (SEZ), North Sulawesi. The method used was a seagrass watch with line transects and quadrant-shaped frames measuring 50x50 cm2. Transect lines were established through the seagrass ecosystem area at 50 m. There were three line transects at each station 25 m apart. Quadrant frame measuring 50x50 cm2. West Likupang has eight seagrass species including C. rotundata, E. acoroides, H. pinifolia, H. uninervis, H. ovalis, O. serrulata, S. isoetifolium, dan T. hemprichii. The health status of the seagrass is currently healthy, with a dense percentage of coverage. The identification of potential risks from anthropogenic activities such as the household disposal of waste at sea, gleaning, the use of boat anchors and propellers, and the construction of infrastructure in coastal areas, such as hotels and harbonurs, pose significant threats.

Abstract

Kompleksitas persoalan lingkungan dan kesejahteraan masyarakat di Kepulauan Tiworo menuntut adanya strategi kebijakan pengelolaan ruang yang lebih komprehensif. Isu pemanfaatan secara tidak berkelanjutan adalah faktor utama yang membutuhkan penanganan berupa formulasi strategi pengelolaan pulau kecil di Kepulauan Tiworo. Penelitian ini bertujuan untuk merumuskan strategi kebijakan pengelolaan ruang pulau-pulau kecil yang berkelanjutan. Metode yang digunakan untuk menilai keberlanjutan dan sensitivitas atribut adalah metode Rapid Appraisal for Land Use (Raplanduse). Strategi kebijakan pengelolaan dilakukan berdasarkan tingkat pengaruh dan ketergantungan atribut-atribut sensitif yang dianalisis dengan analisis prospektif. Hasil penelitian menunjukkan bahwa tingkat keberlanjutan pemanfaatan ruang pulau-pulau kecil di Kepulauan Tiworo cukup bervariasi, mulai dari kategori baik, buruk, hingga kategori kurang berkelanjutan. Atribut sensitif dalam dimensi ekologi adalah material padatan tersuspensi, dan suhu permukaan laut. Dalam dimensi sosial atribut yang sensitif adalah kejadian konflik, dan sumber daya manusia. Dalam dimensi ekonomi adalah atribut tingkat pendapatan, ketersediaan modal usaha, dan produksi tangkapan. Dalam dimensi hukum dan kelembagaan atribut yang sensitif adalah atribut status kepemilikan lahan, dan zonasi kawasan. Kebijakan pengelolaan berdasarkan atribut-atribut sensitif tersebut meliputi peningkatan kapasitas adaptasi masyarakat, mengendalikan pemanfaatan lahan di wilayah DAS di daratan, mengembangkan diversifikasi usaha, menertibkan penggunaan ruang, dan meningkatkan kualitas sumber daya manusia.

Abstract

Pengembangan Mata Pencaharian Alternatif yang berkelanjutan diperlukan untuk melestarikan ekosistem mangrove. Oleh karena itu, penelitian ini bertujuan untuk menentukan jenis mata pencaharian alternatif yang layak untuk dikembangkan. Metode pengumpulan data dilakukan dengan studi pustaka, observasi dan survei serta Participatory Rural Appraisal (PRA). Analisis data menggunakan metode Total Economic Valuation (TEV), analisis tingkat kesejahteraan, analisis kelayakan usaha, analisis SWOT, analisis pola hubungan pemangku kepentingan dan analisis skala penilaian. Hasil penelitian merekomendasikan delapan MPA yang layak untuk dikembangkan di wilayah pesisir Desa Karangsong. Mereka adalah sirup bakau, penyok bakau, kecap, kopi, wedang pantai, dodol, cokelat, dan minuman segar. Kedelapan MPA tersebut menunjukkan adanya kesamaan dalam hal penyediaan bahan baku dan ketersediaan tenaga kerja berdasarkan analisis Rating Scale. Nilai ekonomi total (TEV) menunjukkan bahwa manfaat langsung memiliki nilai ekonomi terbesar dibandingkan dengan manfaat tidak langsung. Hal ini dapat diartikan bahwa manfaat ekonomi dari ekosistem mangrove akan semakin besar jika ekosistem tersebut dapat dipelihara dengan baik, sehingga memberikan manfaat yang berkelanjutan. Hasil penelitian dapat disimpulkan bahwa peningkatan kesejahteraan penduduk Desa Karangsong tidak dapat mengandalkan mata pencaharian mereka saat ini, tetapi perlu mengembangkan delapan MPA secara berkelanjutan untuk meningkatkan kesejahteraan setiap rumah tangga masyarakat pesisir.

Abstract

Restorasi ekosistem karbon biru, seperti mangrove, semakin banyak digunakan untuk mitigasi perubahan iklim dengan menghilangkan dan menyerap karbon di atmosfer. Rehabilitasi penanaman mangrove yang dilakukan oleh Balai Taman Nasional Kepulauan Seribu (TNKpS) sejak tahun 2005 di Kepulauan Seribu merupakan salah satu upaya penurunan emisi secara nasional. Namun, pertumbuhan mangrove dan persebaran mangrove cenderung tidak optimal dikarenakan kondisi lingkungan yang tidak mendukung. Hal ini tentu berdampak pada jumlah stok karbon yang tersimpan dalam mangrove. Oleh karena itu, penelitian ini bertujuan untuk 1) mengestimasi potensi stok karbon pada mangrove rehabilitasi baik tegakan dan substrat, dan 2) menghitung valuasi ekonomi mangrove sebagai penyimpan karbon. Perhitungan stok karbon mangrove pada tegakan dan bawah permukaan menggunakan metode non destruktif (rumus alometrik), sedangkan perhitungan karbon tanah dilakukan menggunakan perhitungan kadar C-Organik dengan metode Walkley & Black. Cadangan total karbon (aboveground, belowground, dan karbon tanah) pada mangrove Rhizophora stylosa adalah 634,54 tonC/ha dan serapan CO2 2328,75 tCO2/ha dengan nilai ekonomi jasa lingkungan dari mangrove rehabilitasi di Pulau Harapan dan Kelapa mencapai Rp375.202.308 untuk pasar bebas dan Rp980.528.697 untuk pasar wajib (Clean Development Mechanism). Hasil penelitian ini dapat dijadikan sebagai informasi awal perumusan kebijakan pengelolaan ekosistem mangrove sebagai penyimpan karbon agar ekosistem mangrove dapat berkelanjutan.

Abstract

Article Highlights:- First study on Liqcoris, an organic pesticide made from coconut waste.- 15% Liqcoris concentration effectively inhibits pests and plant pathogens.- Active compounds include phenol and carbamic acid.- Pest and fungal pathogens were isolated directly from diseased plants in a school garden.- Coconut waste-based pesticide offers practical, eco-friendly pest control solutions. Abstract:Sustainable control of plant diseases is essential to maintain biodiversity. Learning using prototypes is an effort to support students in understanding and learning science and technology in order to answer problems related to biodiversity loss. The research aimed to: 1) produce a prototype of Liqcoris organic pesticide (BLM 06) from coconut shell and shell waste, 2) measure the ability of the Liqcoris organic pesticide in inhibiting the growth of plant pathogenic microorganisms, and 3) study the content of  Liqcoris organic pesticide. The data obtained were statistically analyzed using the SAS Version 9.0 program. The analysis carried out was the analysis of variance (ANOVA). Duncan's advanced test was used at the 5% level to determine the differences among the treatments, i.e., 00 = control or without PDA + pesticide; 10 = PDA +  pesticide concentration 10%; 15 = PDA + pesticide concentration 15%, 20 = PDA + pesticide concentration 20%, and 25 = PDA + pesticide concentration 25%. Based on in vitro test, the study showed that Liqcoris concentration of 15% proved effective in killing phytopathogen fungi (P < 0.05), including Fusarium equiseti, Fusarium graminearum, Nigrospora sphaerica and Colletotrichum gloeosporioides. Treatments with various concentrations of 15%, 20%, and 25% effectively produced inhibitory values ​​in the diameter of pathogenic fungal colonies, respectively 0.118 cm, 0.000 cm, and 0.000 cm that were significantly different from concentrations of 10% (2.7140 cm) and control 0% (5.2180 cm). Considering the economic value of production, the best concentration of organic pesticides chosen was 15%. On the other hand, in vivo test results indicated that in controlling mosaic viruses on diseased curly chili variety TM 999, without Liqcoris treatment (control), the intensity of disease attack increased by 20.22% after 6 weeks after treatment (wat). Meanwhile, after applying Liqcoris organic pesticide with a concentration of 15%, the percentage of mosaic virus attacks decreased to 2.72% after 6 wat (P < 0.05). This study showed that the content of 15% Liqcoris organic pesticide was dominated by active compound phenol (35.16%) and carbamic acid, phenyl ester (23.61%).
