Abstract

Hutan mangrove merupakan ekosistem yang berada di daerah pasang surut di wilayah pesisir, pantai, dan pulau-pulau kecil. Luas hutan mangrove semakin berkurang akibat konversi hutan mangrove menjadi tambak, perkebunan, dan eksploitasi kayu. Kegiatan rehabilitasi ekosistem mangrove perlu dilakukan melalui penanaman. Avicennia alba merupakan jenis mangrove pionir yang tumbuh pada habitat rawa mangrove di lokasi pantai yang terlindung, juga di bagian yang lebih asin di sepanjang garis pantai. Tujuan penelitian ini adalah menganalisis pengaruh media tanam dan intensitas naungan terhadap pertumbuhan bibit Api-Api (Avicennia alba). Penelitian ini menggunakan rancangan percobaan dua faktor dalam rancangan acak lengkap (RAL). Faktor pertama yaitu media tanam dan faktor kedua adalah intensitas naungan. Hasil penelitian menunjukkan bahwa faktor intensitas naungan paling mempengaruhi pertumbuhan bibit Avicennia alba. Variabel yang terpengaruhi antara lain tinggi, diameter, jumlah daun, berat basah total (BBT), dan berat kering total (BKT). Kombinasi perlakuan yang memberikan hasil terbaik adalah A2N0, yaitu media tanam berupa campuran antara lumpur, pasir, dan kompos serta tanpa diberi naungan (naungan 0%). Kata kunci: Avicennia alba, fotosintesis, intensitas naungan, media tanam, pertumbuhan

Abstract

The private forest is one of alternatives that played an important role in fulfillment of a need raw materials management industry wood and the needs of wood. Development of private forest can improve the people and land revenue increase productivity. Research conducted in sub-district Leuwisadeng, Cigudeg, and Jasinga shows that there are some marketing actors involved in marketing wood of the private forest of them are farmers, traders, and sawmill industries. The marketing of the three actors formed four marketing channels are grouped based marketing actors and average skidding distance. Channels that most efficient among fourth the channels is a channels II with the percentage of farmer’s share as 46.93 % and the ratio of K/B by 5.45. Types of plants most favored by farmers and consumers is the type of sengon it because sengon having a short, the age of harvest readily grows, and easy cultivation. The consumer likes kind of plant is because sengon have reachable prices, sengon not easily bad condition wood and widely available in market.

Abstract

One of the provinces in Indonesia that experiences forest and land fires every year is Aceh Province. Aceh Barat District is one of the districts in Aceh Province where forest and land fires occur every dry season. Forest and land fires prevention can be done by utilizing hotspot data for analysis using geographic information systems (GIS). This research aims to analyze the distribution of hotspots and the correlation between rainfall and hotspots as an indicator of the occurrence of forest and land fires in West Aceh Regency in 2014-2019. This research uses MODIS LAPAN hotspots data, land cover distribution maps, peat land distribution maps, administrative maps and rainfall data from BMKG. The correlation between rainfall data and hotspot data was carried out by the bivariate pearson correlation test. The resuls of the research found that there were 576 hotspots in West Aceh Regency from 2014-2019. The district with the highest number of hotspots is in Samatiga District, namely 131 hotspots. The most dominant hotspots are in the peatland cover, as much as 64% and in the swamp scrub land cover area with 126 hotspots. Correlation test results show that rainfall with a negative correlation, that the decrease in rainfall is followed by an increase in hotspots. Keywords: Aceh Barat, fires, GIS, hotspot, rainfall

Abstract

Illegal disposal of used oil causes soil contamination which can damage and reduce the soil productivity. Planting salam (Syzygium polyanthum) with the addition of cow manure and wood charcoal is expected to improve the characteristics of soil that was contaminated by used oil. This study analyzed the effect of giving cow fertilizer and wood charcoal on the growth of salam and determining the optimal dose to increase the growth of salam on contaminated soil by used oil. This study used a factorial completely randomized design (CRD) with two factors; that is cow manure and wood charcoal and using 60ml/kg of soil contaminated with used oil. This study shows that giving 90 gram of cow manure and 40 gram of wood charcoal gave the best response to total wet weight and root length. The application of 90 gram of cow manure and 20 gram of wood charcoal gave the best response to the diameter and application of 90 gram of cow manure gave the best response to the total dry weight of salam seeds. Giving cow manure and wood charcoal can also reduce the Pb content by 0,43 ppm. Keywords: cow manure, Syzygium polyanthum, used oil, wood charcoal

Abstract

Kebakaran hutan merupakan salah satu bentuk gangguan hutan yang sering terjadi. Kebakaran hutan di Indonesia setiap tahunnya sering terjadi saat musim kemarau. Faktor penyebab kebakaran hutan di Indonesia yaitu disebabkan oleh faktor alam dan faktor manusia. Kebakaran hutan menimbulkan kerugian yang besar apabila tidak dilakukan pengendalian kebakaran hutan dengan baik. Penelitian ini bertujuan menganalisis faktor penyebab terjadinya kebakaran hutan dan mengkaji upaya dalam pengendalian kebakaran hutan serta partisipasi masyarakat dalam pengendalian kebakaran hutan di BKPH Slarang, KPH Pemalang, Jawa Tengah. Kebakaran hutan tertinggi terjadi pada tahun 2015 dengan frekuensi 4 kali serta luas total lahan yang terbakar 11,10 Ha. Kebakaran hutan di BKPH Slarang tersebut menyebabkan kerugian sebesar Rp50.234.000. Bentuk pengendalian yang dilakukan oleh pihak BKPH Slarang yaitu sosialisasi atau penyuluhan mengenai kebakaran. Sosialisasi atau penyuluhan langsung tersebut diberikan kepada masyarakat dalam berbagai kegiatan. Peran masyarakat dalam pengendalian kebakaran hutan di BKPH Slarang sangat tinggi dalam pencegahan maupun pemadaman di BKPH Slarang KPH Pemalang. Kata kunci : BKPH Slarang, faktor penyebab, partisipasi masyarakat, pengendalian kebakaran hutan

Abstract

Puspa (Schima wallichii (DC.) Korth.) merupakan jenis tumbuhan yang mendominasi di kawasan Taman Nasional Gunung Halimun Salak terutama di Resort Kawah Ratu. Jenis puspa termasuk salah satu jenis tumbuhan dataran tinggi yang dapat tumbuh di lahan kritis. Tujuan penelitian ini adalah untuk mengidentifikasi pola penyebaran dan potensi permudaan jenis puspa (Schima wallichii (DC.) Korth.) di Resort Kawah Ratu, Taman Nasional Gunung Halimun Salak, Jawa Barat. Pengambilan data dilakukan dengan analisis vegetasi dengan metode petak tunggal seluas 1 ha pada setiap lokasi. Penelitian dilakukan di Blok Pamengpeuk dan Blok Leles. Jenis yang ditemukan pada kedua lokasi penelitian sebanyak 98 jenis. Hasil penelitian menunjukkan pola penyebaran puspa (Schima wallichii (DC.) Korth.) adalah mengelompok, baik di Blok Pamengpeuk maupun di Blok Leles. Penyebaran mengelompok menandakan adanya pertumbuhan permudaan yang baik. Kemampuan regenerasi puspa di kedua lokasi tergolong baik karena jumlah individu permudaan puspa lebih banyak dari pada individu pohonnya.. Kata kunci: pola penyebaran, Puspa, Resort Kawah Ratu, Schima wallichii, Taman Nasional Gunung Halimun Salak

Abstract

Waingapu is one of the areas in Nusa Tenggara Timur Province which often suffered from savanna fires. Savanna fires prevention can be done by utilizing hotspot data for analysis using Geographic Information System (GIS). The climate is one of factors influence the occurrence of savanna fires in Waingapu. The purpose of this study was to analyze the relationship between precipitation, SST anomalies, and the occurrences of savanna fires in Waingapu. This research was conducted on February April 2021 at the Forest and Land Fires Laboratory, Department of Silviculture, Faculty of Forestry and Environment, IPB University. The data used are MODIS and VIIRS hotspot data, daily precipitation data and SST 3.4 anomaly data. The results showed that precipitation was inversely related to hotspots with a negative correlation value. SST anomaly is inversely related to precipitation a negative correlation value. While the SST anomaly with hotspots is directly proportional with a positive correlation value. Keywords: climate, hotspot, Geographic Information System (GIS), Waingapu
