Abstract

Sengkubang Village is a mangrove area located in Mempawah Hilir District, Mempawah Regency, West Kalimantan. Sengkubang Village already has a Coastal Community Group that cares about the preservation of mangroves. However, community empowerment still needs to cover women's communities. Most women in Sengkubang Village work as housewives or help their husbands with the gardens. The implementation of community service focuses on empowering the women of Sengkubang Village by providing skills based on natural wealth and plantation products around their residences. Through this skills training, it is hoped that women will be able to fill their spare time by producing banana flour and brownies made from banana flour which are of the sale value. The method of implementing PKM is through short skills training, and participants can bring home their work. The evaluation of PKM activities was carried out using the questionnaire method at the end of the training. The training results showed the enthusiasm of the women's group from the Pelesir community in making banana flour and brownies made from banana flour. 100% of participants strongly agreed that the theme and training could develop their potential to increase their income and daily activities. Subsequent developments will include product marketing assistance through social media and e-commerce.

Abstract

Pangari activity is a mutual cooperation activity in farming carried out by the Dayak people in West Kalimantan. However, there is no scientific information that examines the use of plants in pangari activities by the Dayak Ribun people in Suka Gerundi Village, Parindu District, Sanggau Regency. Therefore, this research was carried out with the aim of finding out how the pangari activities were carried out by the Dayak Ribun people, identifying the types of plants, the proportions of plant organ parts, and the benefits of the forms of the types and plant organs used. This research was conducted for 6 months, from March to September 2022. The method used in this study was the snowball sampling method with 15 respondents. The results showed that the pangari activities carried out took place at the time of planting and harvesting rice. 58 species from 32 plant families were used. The highest Citation Frequency value is rice (Oryza sativa L.) at 100%. The most commonly found plant families are Arecaceae, Moraceae, Poaceae, and Zingiberaceae. The percentage of plant parts that are widely used are leaves (31%). Forms of utilization of plants, namely, as building materials, crafts, medicines and food. The highest Informant Agreement Ratio (IAR) value is a form of utilization as food with a value of 0.8156.

Abstract

Nepenthes is a carnivorous plant that can cross-pollinate the same or different species so that it can produce hybrid Nepenthes. An analysis of the relationship between Nepenthes species and their hybrids can be carried out by observing the morphological characters. The purpose of this study was to determine the morphological characteristics and the relationship between Nepenthes hybrids and their parents. This study used Nepenthes hybrid resulting from a cross between N. mirabillis and N. reinwardtiana which were found in Entikong District, Sanggau Regency. The relationships were analyzed using the NTSys program with the UPGMA method. Nepenthes reinwardtiana does not have variations in pitcher color or shape. Nepenthes mirabillis and N. mirabillis X N. reinwardtiana had variations in pitcher color and shape. Nepenthes hybrid has a characters inherited from both parents. Nepenthes reinwardtiana, N. mirabillis, and N. mirabillis X N. reinwardtiana had a similarity level of 0.46 and were divided into three clusters. The relationship between N. mirabillis and N. mirabillis X N. reinwardtiana has the greatest similarity coefficient value of 0.77, while N. reinwardtiana and N. mirabillis X N. reinwardtiana have a similarity coefficient value of 0.64. Morphological characters show clear differences in the pitcher. The relationships of Nepenthes hybrid is closer to N. mirabillis.

Abstract

Mangrove ecosystem is one of the largest carbon storage sheds on earth, has enormous environmental benefits in disaster mitigation, as well as a source of livelihood for coastal communities. The purpose of this research is to know the aboveground biomass distribution of mangrove forest stand and to know the potency of carbon reserve of mangrove forest area of Mempawah Regency. The research was conducted from September to October 2017 in mangrove forest of Sungai Pinyuh district of Mempawah Regency. Aboveground biomass measurements are performed in a 50 x 50 m measuring plot, data collection is performed by listing each stand with dbh ? 5 cm and grouping it in diameter classes. Aboveground tree biomass estimation was performed using allometric equations and organic carbon stocks calculated by converting biomass by conversion factor of 0.5. The results showed the biomass value ranged from 32.37 to 55.84 tons / ha with an average value of 40.28 tons / ha. The highest biomass is distributed in diameter class 15-25 cm with the percentage 23.10% and lowest in class diameter> 55 cm with contribution equal to 13.39%. Carbon stock in mangrove stand biomass ranged from 16.18-27.91ton C / ha with average value 20.14 ton C / ha. Avicennia officinalis is an important type with the contribution of carbon reserves of 98.99%.Keywords: aboveground biomass, Carbon stock, mangrove forest, Mempawah Regency.AbstrakEkosistem mangrove merupakan salah satu gudang penyimpanan karbon terbesar di bumi, memiliki manfaat lingkungan yang besar dalam mitigasi bencana, serta sebagai sumber mata pencaharian masyarakat pesisir. Tujuan penelitian ini adalah untuk mengetahui distribusi aboveground biomass tegakan hutan mangrove dan mengetahui besarnya potensi cadangan karbon kawasan hutan mangrove Kabupaten Mempawah. Penelitian dilaksanakan dari bulan September hingga Oktober 2017 di hutan mangrove kecamatan Sungai Pinyuh Kabupaten Mempawah. Pengukuran biomassa atas permukaan (aboveground biomass) tegakan dilakukan di dalam petak ukur ukuran 50 x 50 m, pengumpulan data dilakukan dengan mendata tiap tegakan dengan dbh ? 5 cm dan mengelompokkannya dalam kelas-kelas diameter. Pendugaan biomassa aboveground pohon (aboveground tree biomass) dilakukan dengan menggunakan persamaan allometrik (Komiyama et al., 2008) dan stoks karbon organik dihitung dengan mengkonversikan biomassa dengan faktor konversi sebesar 0,5. Hasil menunjukkan nilai biomasa berkisar antara 32,37-55,84 ton/ha dengan nilai rata-rata 40,28 ton/ha. Biomasa tertinggi terdistribusi pada kelas diameter 15-25 cm dengan persentase 23,10% dan terendah pada kelas diameter >55 cm dengan kontribusi sebesar 13,39%. Stoks karbon pada biomasa tegakan mangrove berkisar antara 16,18-27,91 ton C/ha dengan nilai rata-rata 20,14 ton C/ha. Avicennia officinalis merupakan jenis penting dengan kontribusi stoks karbon sebesar 98,99%.Kata kunci: Aboveground biomass, hutan mangrove, Kabupaten Mempawah, Stok karbon.

Abstract

Pemetaan kawasan mangrove melalui data citra satelit dapat memberikan informasi terkini mengenai kondisi dan sebaran mangrove yang ada. Penelitian ini bertujuan untuk memetakan kawasan mangrove yang berada di tiga kecamatan di Kabupaten Mempawah, yaitu Kecamatan Siantan, Segedong dan Sungai Pinyuh, serta memetakan kondisi eksisting kawasan mangrove saat ini. Metode yang digunakan pada penelitian ini adalah dengan kombinasi pendekatan penginderaan jauh dan survey lapangan. Melalui hasil analisis, luasan mangrove diestimasi sebesar 592,56 di Kecamatan Siantan, 287,91 Ha di Kecamatan Segedong dan 245,25 Ha di Kecamatan Sungai Pinyuh. Nilai indeks vegetasi (Normalized Difference Vegetation Index) berkisar antara 0,20 hingga 0,81, dominan kondisi vegetasi berada dalam kondisi baik dengan nilai indeks vegetasi yang tinggi. Terdapat titik-titik di lokasi yang mengalami degradasi dengan nilai indeks vegetasi berkisar 0,20 hingga 0,61. Kondisi eksisting hutan mangrove di 3 kecamatan dapat dikatakan baik, namun terdapat beberapa titik-titik yang mengalami degradasi atau kerusakan secara parsial.
