Suli Village, Salahutu Sub District, Central Maluku Districts is one of the coastal villages located in the east and directly opposite Baguala Bay, Ambon Island. As a Coastal Village, Suli has various potentials for biological natural resources. This existing potential must be managed by taking into account the conservation aspects, namely, protection, preservation, and utilization, to remain sustainable. The problems that arise in Suli Village include the lack of sensitivity among the community to be able to manage the environment properly. If left unchecked, natural resources which are the potential for development will be damaged and cause other problems in society. This is a challenge in the management of natural resources and existing ecosystems because they must maintain a balance between meeting human needs and the sustainability of their use to support life in development. To realize sustainable development, one of the efforts that can be done is to implement conservation activities as mandated in Constitution Number 5 of 1990. One way to do this is to carry out community service activities. This activity aims to conserve natural resources and the biodiversity contain while at the same time encouraging the achievement of sustainable development goals starting from the smallest community groups. The activities carried out are socializing the importance of living natural resources and their conservation efforts, environmental problems due to waste, and encouraging environmental conservation activities by becoming a customer of a waste bank. Finally, this service activity also indirectly contributes to the achievement of several goals and targets in the SDGs. Among the goals achieved were the environmental pillars, especially Goal 13 (handling climate change) and Goal 15 (terrestrial ecosystems).

Sago forests (Metroxylon sp) in Tulehu Village, Salahutu District, Central Maluku Regency are one of the staple food sources of the Maluku community that have been consumed for generations. Various parts of sago from leaf stalks to trunks have been widely studied. However, research related to sago biomass has not been done much. In this regard, this paper aims to determine the potential biomass and carbon reserves stored in sago forests in Tulehu Village for the purposes of handling climate change. The biomass and carbon content reserves to be determined are sago at the pole and tree levels. The method used was 3 survey routes with 30 measurement plots using purposive sampling, observation, then analysis and estimation of biomass and stored carbon reserves. The calculation results at the pole level of sago obtained a biomass of 27 tons/ha and stored carbon reserves of 14 tons/ha. At the tree level of sago, a biomass of 42 tons/ha and stored carbon reserves of 20 tons/ha were obtained.

River flow recession analysis plays a crucial role in understanding how watersheds release water during dry periods. Consequently, modeling baseflow recession is closely related to the characteristics of unconfined aquifers, storage behavior, and the discharge properties of the watershed. While several theories exist on modeling recession curves, limited research has compared different approaches regarding baseflow recession characteristics. This study aims to model seven baseflow recession equations in paired watersheds in Ambon City. The research methodology involves calibrating seven baseflow recession models using the Recession Curve (RC) 4.0 Hydro Office software. The tested models include Linear Reservoir, Exponential Reservoir, Double Exponential Horton, Dupuit-Boussinesq Aquifer Storage, Depression Storage, Turbulent Flow Model, and Hyperbolic Function Model. The calibration results yield optimal combinations of recession parameters. The parameterization order from highest to lowest is as follows: Depression Storage, followed by the Hyperbolic Function, Exponential Reservoir, Turbulent Flow Model, Double Exponential Horton, Linear Reservoir, and Dupuit-Boussinesq Aquifer Storage. Quantifying baseflow recession constants and coefficients is essential for understanding baseflow behavior. Visualizing the slope of the Recession Curve (MRC) reveals that models with high recession constants tend to have gradual MRCs, while low recession constants result in steep MRCs. The MRC slope further describes the relationship between storage conditions and discharge from the watershed. The advantage of creating MRCs from discontinuous recession segments lies in their ability to appropriately describe the MRC process and provide quantitative parameters relevant to drainage mechanisms. MRCs also serve as an optimal automated computational tool.

Lychee plants are commercial fruit plants, on Ambon Island they grow along the Negeri Hative Besar road. They are local lychee plants (Litchi chinensis Sonn Var. Amboinensis) which grow in home gardens as landscape plants and have not been commercially cultivated. This cultivar has adapted to the lowland environment, namely 5 - 400 m above sea level with rainfall of 2500-3000 mm/year, minimum temperature of 23.4-25.6°C and humidity of 82.3-87.4%. Lychee on Ambon Island is widely cultivated as a yard plant in Negeri Soya, Naku, Hatalai, Hukurila, Ema, Amahusu, Eri, Lateri, Tulehu, Hative Besar and Tawiri as well as other villages in the Lease Islands (Haruku Island, Saparua and Nusalaut), South Seram and West Seram. The yield of lychee fruit in these areas is still very low with a quality that cannot be maintained as an exotic fruit that has commercial economic value because the fruit skin cracks and its taste is sour because it has not received good praktice agrotechnology. The application of appropriate lychee cultivation technology through socialization activities, demonstrations and assistance in providing Complete Organic Liquid Plant Nutrition Landetox to lychee trees in the yards of the community in Negeri Hative Besar, Teluk Ambon sub-district, Maluku province has provided an increase in high yields with satisfactory lychee fruit quality and marketable as a promising source of income for the community.

Penggunaan Biopestisida Nabati Dari Bahan Dasar TOGA Untuk Pengendalian Hama Rayap Pada Pembibitan Pala Dan Cengkeh Milik Kelompok Tani Spirit Di Desa Liliboi Latumahina, Fransina; Mardiatmoko, Gun; Tjoa, Marthina

Rayap adalah serangga sosial yang berasal dari ordo Isoptera dapat menimbulkan kerugian ekonomi yang cukup tinggi, dimana rayap akan menyerang bagian batang hingga akar tanaman akibatnya daun tanaman akan menguning, batang akan membengkak dan akar tanaman terputus. Serangan rayap yang terjadi secara terus - menerus akan semakin sulit dibasmi apabila tidak mendapat perhatian yang serius oleh petani. Petani Desa Liliboi mengalami kesulitan dalam budidaya tanaman pala dan cengkeh karena setiap tahun selalu diserang oleh rayap dengan intensitas kerusakan sedang hingga tinggi dengan luas serangan lebih dari 50 %. Kondisi ini sangat berdampak buruk terhadap kualitas maupun kuantitas tanaman yang dibudidayakan didalam areal hutan kemasyarakatan Desa Liliboi. Warga kehilangan tanaman Pala dan Cengkeh bahkan terjadi penurunan pendapatan masyarakat dari pengelolaan hutan rakyat milik petani hutan. Pengendalian hama rayap umumnya dilakukan oleh petani setempat dengan menggunakan bahan kimia diantaranya Furadan, Sutrin 100 EC dan Bantrek 480 EC yang harganya sangat mahal dan sulit terjangkau oleh kelompok tani, akibatnya mereka selalu merugi tiap tahunnya. Untuk itu perlu dicari solusi yang tepat dalam menangani persoalan yang dihadapi oleh kelompok tani Desa Liliboi. Salah satu solusi yang dapat ditawarkan kepada petani yakni penggunaan biopestisida nabati dari Tanaman Obat keluarga (TOGA) yang mudah dan murah didapat untuk memberantas serangan rayap yakni Sereh, Daun Pepaya dan Daun Sirsak. Biopestisida nabati memiliki keuntungan antara lain mudah terurai di alam sehingga tidak mencemari lingkungan serta relatif aman bagi manusia dan hewan peliharaan karena residunya mudah hilang. Penggunaan biopstisid nabati dalam dalam jumlah (dosis) yang kecil atau rendah, mudah diperoleh di alam, dan cara pembuatannya relatif mudah dan secara sosial ekonomi penggunaannya menguntungkan bagi petani kecil. Pembuatan biopestisida secara sederhana berorientasi kepada penerapan usaha tani berinput rendah, sehingga target yang akan dicapai dari kegiatan PKM yakni meningkatnya pengetahuan dan ketrampilan kelompok tani hutan melalui perbaikan sistem budidaya dan pemeliharaan tanaman pala dan cengkeh hutan, peningkatan kemampuan petani dalam mendiagnosa gejala serangan hama rayap pada pala dan cengkeh serta kemampuan petani meracik obat pembasmi hama rayap secara masal dari bahan TOGA untuk meningkatan produktivitas tanaman sehingga pada akhirnya akan meningkatkan kesejehteraan ekonomi masyarakat petani. Kegiatan yang akan dilaksanakan yakni penguatan kapasitas kelompok tani melalui kegiatan penyuluhan tentang budidaya tanaman pala dan cengkeh, pengenalan gejala dan tanda serangan rayap, peracikan bahan obat pembasmi hama rayap dan pembuatan biopestisida nabati dari tanama obat keluarga (TOGA) yakni Daun Sereh, Daun Pepaya dan Daun Sirsak dalam bentuk larutan. Oleh sebab itu dilaksanakan kegiatan pengabdian masyarakat untuk mencari solusi yang dihadapi masyarakat yang dilakukan dengan 2 cara yaitu: (1) presentasi materi biopestisida, budidaya pala-cengkeh yang diikuti dengan diskusi dan (2) demo pembuatan biopestisida dari bahan tanaman obat keluarga daun pepaya, sereh dan daun sirsak. Hasil diskusi yang berlangsung selama kegiatan presentasi terungkap banyaknya pertanyaan dari peserta yang belum banyak memahami budidaya pala dan cengkeh serta penggunaan biopestisida guna mendukung pertanian organik, juga tentang pemahaman mengenai cara perawatan pala-cengkeh, pembuatan biopestisida nabati dari tanaman obat keluarga yang bahan-bahannya mudah didapat didesanya. Demo pembuatan biopestisida berjalan dengan lancar dimana peserta juga terlibat aktfif dalam demo tersebut sehingga diharapkan nanti mereka bisa membuat sendiri biopestisida untuk memenuhi kebutuhan kelompok tani.

The pitih wood plant (Melaleuca leucadendra) is a type of plant that belongs to the guava tribe (Myrtaceae) which can produce one of the essential oil products in Indonesia. Eucalyptus plants can be cultivated by generative (seed) and vegetative propagation methods (shoot cuttings with rejuvination techniques, branch cuttings, shoot cuttings, root cuttings, grafts). However, related to the root structure of the rhizome and the value of the biomass content of this plant, it has not been widely published. This is the impetus to conduct research related to the root structure of the rhizome and the biomass content and stored carbon content of the eucalyptus plant section by direct measurement methods in the field and analysis in the laboratory. From the plot of eucalyptus plants, it can be seen that the selected sample has sturdy rhizome roots with similar plant height characteristics, both for the growth rate of the mother plant and the saplings of the mother plant which generally have an even height and are not too.

This study aims to know about the factors that influenced land cover changes in Gunung Sirimau Protected Forest Area. The method used in this study is crosstab analysis with a chi-square test, which is used to know the correlation between one variable and another variable. This study showed that people's dependence on forests influenced the land cover change in the Gunung Sirimau Protected Forest area. At the same time, other factors such as the income of people, knowledge about forest boundaries, and natural disasters did not influence land cover change in Gunung Sirimau's protected forest.

Generally, in the preparation of multiple linear regression or allometric equations, the T and F tests were carried out directly, while various tests are not performed. Therefore, this study aims to provide examples of establishing a good and complete regression equation by presenting a case study of preparing young canary allometric equations. Furthermore, Canary (Canarium Indicum L) was selected because it provides environmental services, especially in handling climate change, which has not been much studied. This article also attempts to establish the allometric equations of young canaries to be used in dealing with climate change. The results obtained by the allometric equation Y = -941,765 + 399,903 X1 + 3,429 X2, showed that it was good because it has undergone several tests, but cannot be operationalized due to the low determinant value of RSquare: 0.318. In order for allometric equations to work and function properly, it is necessary to perform various tests first and once the regression equation is obtained, it should be supported by a high RSquare value
