Abstract

ABSTRAK Lahan gambut tropika memiliki fungsi sangat penting yang terkait dengan masalah konservasi, terutama fungsi simpanan dan rosot karbon, yang mempengaruhi perubahan iklim global. Namun, lahan gambut mengalami berbagai  tekanan  dari  penggunaan lahan  yang  beragam termasuk pembangunan kehutanan, drainase  pertanian,  energi,  dan  hortikultura.  Tujuan  penelitian  ini  yaitu  untuk  mendapatkan  informasi biomasa hutan gawa gambut tropika terutama di Kalimantan Tengah pada berbagai kondisi penutupan lahan. Penelitian pada biomasa rawa gambut dilaksanakan pada beberapa jenis penutupan lahan yaitu hutan rawa gambut primer, hutan bekas tebangan, dan kawasan bekas terbakar. Metode destruktif diterapkan pada tiga petakan berukuran 10 x 10 m2. Contoh masing-masing bagian vegetasi seperti batang, cabang, ranting, dan daun diambil untuk analisis kadar air. Hasil penelitian menunjukkan bahwa ada suatu perbedaan biomasa di atas permukaan tanah yang nyata antara hutan rawa gambut yang relatif masih baik, hutan bekas tebangan, dan kawasan terbakar. Rata-rata jumlah biomasa adalah antara 400-900 ton/ha untuk hutan rawa gambut yang relatif masih baik, 240-400 ton/ha untuk hutan bekas tebangan,  210-460 ton/ha untuk kawasan bekas kebakaran tahun 1997, dan antara 15 hingga 21 ton/ha untuk kawasan yang dua kali mengalami kebakaran.

Abstract

The Bukit Tangkiling Park area was determined based on the Decree of the Minister of Agriculture of the Republic of Indonesia number: 046/Kpts/Um/1/1977 on January 25, 1997, with an area of 533 Ha. Bukit Tangkiling Nature Park has sloping lowlands, undulating to hilly terrain, and very steep slopes of 2% to 45% at 25 to 170 metres above sea level. Year-to-year tourism increases. An increase in tourist visits can damage natural resources and the environment by exceeding the carrying capacity and capacity of the environment. Cifuentes (1992)'s method is used to calculate the natural tourist environment's carrying capacity in protected areas. The assessment to determine the maximum number of visits to a tourist area is based on the physical, biological and management conditions in the tourist area by considering three main aspects; physical carrying capacity (PCC), real carrying capacity (RCC) and effective carrying capacity (ECC). The research was conducted with the aim of analyzing the value of the effective carrying capacity (ECC). The maximum number of tourists that can visit the Bukit Tangkiling Natural Tourism Park without disrupting the ecology. PCC = 219.063, RCC = 5.475, MC = 0.9, ECC = 4,927 people/day. ECC of 353 people/day. This value is less than the Nature tourist Carrying Capacity Value and does not harm the environment of the natural tourist region. This allows Bukit Tangkiling Park growth.

Abstract

Oil palm is a carbon absorbing plant that stores it in biomass. To monitor biomass, especially in large areas of oil palm plantations, remote sensing data can be used combined with machine learning algorithms. The aims of this study were to estimate oil palm biomass carbon according to age class using non-destructive methods, as well as analyze the relationship between the reflectance of Sentinel 2 image oil palm and oil palm biomass carbon, and estimate the distribution of oil palm biomass carbon using a learning algorithm random forest (RF) engine. Measurement of biomass at the study site was carried out non-destructively using stratified purposive sampling. The closeness of the relationship between Sentinel 2 image and measured oil palm biomass is assessed from the coefficient of determination of the regression equation. Estimation of the distribution of biomass carbon in all research locations was carried out using the RF method with the Dzetsaka classification tool. The results showed that the highest biomass carbon stock was obtained in oil palm aged 20 years with an average of 59.6 tons C/ha, while the lowest biomass carbon stock was obtained in oil palm aged 17 years with an average of 32.9 tons C/ha. The reflectance value of Sentinel-2 image on the blue, green, red, and near infrared channels has a positive correlation to biomass carbon from oil palm with an R² greater than 0.8. The classification of biomass carbon with the RF approach applied to Sentinel-2 image gives an adequate accuracy value of 76.40% in the combination of the proportion of training and testing data 60% : 40%.

Abstract

Peatland is a unique ecosystem with water saturation; peatland regulates hydrological processes, climate, environmental conditions, and biodiversity. Poor management practises regarding peatlands can lead to land degradation, and peatland degradation typically has negative effects. Recent tropical peatland research in Indonesia has predominantly revolved around the examination of the ecological consequences resulting from various management approaches. There is little study on farmers' agroforestry efforts to preserve and restore degraded peatlands. A comprehensive examination was undertaken to assess a range of facts, information, and scholarly articles pertaining to the practise of agroforestry on peatlands in Indonesia. The primary incentive for farmers to adopt agroforestry systems originates from their recognition of the impending scarcity of trees. By integrating intercrops with cultivated trees, farmers anticipate generating adequate money to fulfil their family's economic requirements. Farmers who choose intensive intercropping practises are motivated by market demand, whereas farmers who do not adopt this approach tend to favour crops that necessitate less rigorous management. The provision of governmental assistance holds significant importance, and there is a pressing need for additional guidance and support. The potential for rehabilitating degraded peatlands by the implementation of agroforestry practises of native tree species is considerable. Their growth patterns contribute to enhanced vegetative coverage, resulting in heightened moisture levels, reduced temperatures, diminished fire hazards, and improved peat soil quality. The relationship between the physiography of the land and the depth of the peat is directly associated with the patterns and components of agroforestry in peatland environments.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh polaritas pengelasan terhadap kekuatan tarik pada material baja ASTM A36. Polaritas yang digunakan pada penelitian ini adalah polaritas lurus (DC-) dan terbalik (DC+). Metode pengelasan yang digunakan dalam penelitian ini adalah metode pengelasan SMAW (Shielded Metal Arc Welding). Proses pengelasan yang dilakukan menggunakan dua variasi arus yang berbeda: 80A dan 90A, dan hanya menggunakan elektroda jenis E-7018. Selanjutnya bentuk kampuh pengelasan yang digunakan dalam penelitian ini berbentuk V. Kemudian, untuk proses pengujian tarik, spesimen dibuat dengan mengacu pada standar pengujian ASTM E8. Hasil penelitian ini menunjukkan bahwa proses pengelasan yang menggunakan polaritas DC+, nilai kekuatan tariknya berbanding lurus dengan arus yang diaplikasikan. Sebaliknya, pada polaritas DC-, kekuatan tariknya meningkat seiring dengan berkurangnya besar arus yang digunakan. Menariknya, nilai pada regangan menunjukkan hasil yang berbeda dimana nilai regangan tidak dipengaruhi oleh polaritas pengelasan, tetapi nilai regangan dikontrol oleh arus pengelasan.

Abstract

The aim of training activities in Bahaur Hulu Permai Village is an effort to improve the abilities and skills of people living in peat ecosystems, especially in coastal areas. Coastal areas not only have potential as fisheries resources, but also agriculture in a broad sense. The main income of coastal communities is marine fisheries and brackish water fisheries, if they are in a brackish water ecosystem. The potential for marine and river fisheries and land fisheries in Indonesia is very large. The problem is that people in coastal areas are still unable to manage natural potential into goods or products that have high economic benefits. The importance of increasing the abilities and skills of communities in coastal areas by conducting outreach, counseling and training in making fish-based food. One of the activities that can be improved is making fish sticks, in order to increase income for fishing families in particular, and coastal communities in general.

Abstract

Kegiatan Pengabdian pada Masyarakat ini dilaksanakan pada tanggal 19 Mei 2024 di Desa Talio, Kecamatan Pandih Batu, Kabupaten Pulang Pisau. Kegiatan ini merupakan salah satu upaya dalam meningkatkan keterampilan ibu-ibu rumah tangga di Desa Talio untuk memanfaatkan hasil perkebunan holtikultura yang cukup melimpah di desa tersebut. Hasil hortikultura tersebut adalah pisang dan singkong yang tidak dimanfaatkan secara maksimal oleh masyarakat. Umumnya hasil tersebut dijual dalam bentuk bahan mentah dan belum ada diversifikasi pengolahan dari hasil perkebunan tersebut. Dalam sebuah kegiatan Focus Group Disscussion yang dilakukan pada kegiatan penelitian sebelumnya, masyarakat Desa Talio menginginkan penambahan ketetrampilan dalam bidang tata boga. Mengingat banyaknya hasil panen pisang dan singkong di Desa Talio, maka pelatihan pembuatan kue berbahan baku lokal tersebut dilaksanakan untuk meningkatkan keterampilan masyarakat terutama ibu-ibu sehingga dapat menambahkan penghasilan/pendapatan dalam rumah tangga. Selain itu, kegiatan pelatihan ini juga menjadi solusi bagi masyarakat untuk membantu menanggulangi kerusakan ekosistem lahan gambut. Hasil pelatihan ini memberikan pengetahuan yang baru kepada masyarakat terutama ibu-ibu rumah tangga terkait dengan diversifikasi pengolahan hasil perkebunan hortikultura dan dapat memberikan manfaat secara finansial dalam rumah tangga. Berdasarkan hasil wawancara yang dilakukan sebelum pelaksanaan pelatihan terlihat bahwa hanya 14% ibu-ibu rumah tangga yang mengetahui bahwa pisang dan singkong dapat diolah menjadi berbagai jenis bentuk olahan makanan terutama untuk bahan baku kue, sedangkan 86% yang lainnya mengatakan bahwa mereka belum mengetahui diversifikasi olahan makanan dari kedua bahan tersebut. Namun, setelah pelaksanaan pelatihan terlihat ada peningkatan dari segi pengetahuan dari ibu-ibu rumah tangga yaitu sebesar 100% peserta mengatakan bahwa mereka semua mengetahui tentang diversifikasi olahan pisang dan singkong dari pelatihan yang dilakukan.

Abstract

Microclimate of Developed Peatland of The Mega Rice Project in Central Kalimantan (A Jaya,T Inoue, SH Limin, U Darung and IS Banuwa): In Indonesia peatland covers an area of 16 to 27 Mha and this ecosystem is vitally linked to environmental and conservation issues, as well as its economic value for human survival. These peatlands are, however, the subject of various land use pressures, including forestry, agriculture, energy and horticulture. A field study was carried out 6 years after the end of failed peatland development project shows that inappropriate and unsustainable forms of peatland management have resulted in degradation of the natural forest vegetation, draw-down of the peat water table, increase of peat surface and air temperatures and recurrent surface and ground fires. Implications of microclimate for possible restoration options.

Abstract

Changes of land cover from forest to non-forest areas affect the hydrological cycle and water quality in watershed ecosystems, such as the change of forest into oil palm plantation areas. Increased production and extention of oil palm plantations have impacts on the environment and water quality, which have become one of the environmental issues. The study was conducted to provide an overview of the erosion and surface runoff from forest and oil palm plantations and their impacts on the water quality. Erosion plots with the size of 15 m × 25 m were made on Jalemu Watershed, Gunung Mas Regency, Central Kalimantan Province. The research was conducted to study the impact of land cover changes on erosion and surface runoff and nutrient loss into the Jalemu River Basin. Sampling of sediments and runoff water was carried out from the erosion plots, inlcuding water sampling from Jalemu watershed. The results showed that the erosion and surface runoff that occurred in the 5 years old oil palm area were higher than in the forest area, which implied the loss of nutrients from oil palm plantation areas and the potential for water pollution by the nutrients.
