Abstract

The impact of the use of chemical fertilizers and pesticides has had an impact on the decline in soil fertility. while on the other hand the need for food continues to increase along with the increase in population. Conservation farming efforts with the use of organic fertilizers are a solution to increase soil fertility and quality. Approach efforts to change farmers' mindsets to use organic fertilizers need to be carried out by carrying out counseling, training, mentoring and creating sample plots for plant cultivation. The results of the activity showed an increase in farmers' knowledge by 72% after participating in the dissemination program, as shown through pre-test and post-test evaluations. In addition, farmers began to adopt the use of organic fertilizers on their agricultural land, resulting in increased crop productivity and improved soil quality. This success reinforces the importance of organic fertilizer technology as a solution in maintaining environmental sustainability and supporting farmer independence in the area. With significant results, this approach is recommended to be replicated in other areas with similar conditions.

Abstract

Forests as part of the environment have a big role in maintaining ecosystem stability. One of them is as a carbon store. Vegetation in forests can prevent the release of carbon into the atmosphere through the process of photosynthesis where vegetation absorbs CO2 then breaks it down and stores it in the form of biomass. This is what makes it important for forest friends to study their ability to store biomass and carbon specifically on Agroforestry land as one of the site level forest management units. The aim of this research is to develop an allometric equation model to estimate the value of carbon biomass stored in bellow ground specifically for stands on traditional agroforestry land. The method used is a destructive sampling by selecting sample trees purposively and selecting three samples. trees with different diameters at breast height (dbh) but the same age representing stands on agroforestry land in Aimas District, Sorong Regency. biomass and carbon measurements were carried out through laboratory tests. The total below ground biomass content of the 19 of Paraserianthes falcataria stands obtained was 0.369 tons/ha. The below ground carbon content of sengon stands on 2.8 hectares of agroforestry land is 0.184 tonnes C/ha.

Abstract

Hutan adat merupakan hutan negara dengan sistem pengelolaan hutan yang bertujuan untuk memberdayakan masyarakat tanpa menggangu fungsi pokoknya. Tujuan pemberdayaan masyarakat adalah meningkatkan nilai ekonomi, nilai budaya, memberikan manfaat terhadap masyarakat pengelola dan masyarakat setempat. Hutan adat Kampung Fategomi Distrik Aitinyo Kabupaten Maybrat adalah hutan yang dikelola oleh kelompok masyarakat adat hutan Kampung Fategomi Hutan adat ini dikelola oleh masyarakat Fategomi Distrik Aitinyo Kabupaten Maybrat yang bertujuan melestarikan hutan adat. Kelompok masyarakat tersebut tergabung dalam kelompok tani hutan yang diberi nama Kelompok masyarakat adat kampung fategomi yang memiliki anggota sebanyak 25 orang. Pengabdian ini dilaksanakan di Kampung Fategomi Distrik Aitinyo Utara Kabupaten Maybrat selama 2 bulan yakni bulan Maret-April 2023, Metode yang digunakan dalam pengabdian ini adalah metode deskriptif dengan teknik survey dan wawancara interview yang telah disediakan Quisioner dan disiapkan topik-topik pertanyaan kunci (key quistion). Berdasarka hasil dan pembahasan maka dapat disimpulkan bahwa dari 12 variabel berada pada skala baik dengan rata-rata 2.84, ini menunjukkan variabel yang dipertanyakan menunjukkan persepsi masyarakat terhadap pengelolaan sumberdaya hutan yang dilakukan di hutan adat Kampung Fategomi Sangat Setuju /Sangat Mengetahui/Sangat Perlu/Sangat Berperan/Sangat tergantung/sangat Bermanfaat, Secara umum memenuhi standar pada variabel yaitu pandangan masyarakat tentang Keberadaan hutan adat Kampung Fategomi, Perkembangan Hutan Adat, Pelibatan dalam pengelolaan dan pemeliharaan hutan adat, Penerapan pola pertanian dalam hutan adat

Abstract

This research was carried out in the Sorong Nature Tourism Park (TWA) Forest area from August 2023. This research aims to determine potential, biomass per diameter, biomass per unit area; and the amount of carbon stored in stands of Dipterocarpaceae species in the Sorong TWA forest. The potential stands of dipterocarpaceae species found in the Sorong TWA forest are 398 trees or an average of 39.8 trees/ha. The types of dipterocarpaceae stands found were Resak (Vatica papuana), Mersawa (Anisoptera spp.), and Merawan (Hopea sangol). The distribution of dipterocarpaceae stands is quite even, with the Vatica species being very dominant, namely 156 trees or 15.6 trees/ha, Mersawa with 132 trees or 13.2 trees/ha, and Hopea with 110 trees or 11.0 trees/ha. The total standing biomass of dipterocarpaceae species was 38.82 tonnes/ha, with details for the Vatica species contributing the most biomass, namely 16.58 tonnes/ha, Mersawa 12.49 tonnes/ha and Hopea 9.75 tonnes/ha. Meanwhile, the total biomass per area is 3.88 tons per hectare. The greatest amount of biomass is stored in stands of trees with a diameter > 30 cm compared to those with a diameter < 30 cm. The stored carbon reserve content of dipterocarpaceae stands is 1.78 tonnes/ha, so assuming the Sorong TWA forest has an area of ​​945.90 ha, it is estimated that the amount of carbon stored in dipterocarpaceae stands is 1683.70 tonnes.
