Abstract

Aktivitas masyarakat sekitar hutan sebagian besar bergantung pada kegiatan bercocok tanam, hal ini sangat erat kaitannya dengan pembukaan lahan yang memicu terjadinya kebakaran hutan dan lahan (Karhutla). Peran masyarakat menjadi sangat penting mengingat keberadaannya yang berbatasan langsung dengan hutan dan daerah rawan kabakaran lainnya. Penelitian ini bertujuan untuk mengetahui bentuk kinerja dan faktor penghambat Masyarakat Pedulu Api (MPA) Desa Bontomanurung Kecamatan Tompobulu Kabupaten Maros dalam pengendalian kebakaran hutan dan lahan. Jenis penelitian yang digunakan adalah kualitatif dengan metode deskriftif. Sumber data yang digunakan melalui wawancara, pengamatan di lapangan dan dokumentasi. Hasil penelitian menunjukkan : (1) Upaya pengendalian kebakaran hutan dan lahan yang dilakukan oleh kelompok MPA Ma’bulo Sibatang belum berjalan dengan optimal. Selama ini pemberian informasi ke masyarakat desa dilakukan secara individu dan mandiri oleh masing-masing anggota kelompok bukan sebagai 1 (satu) kelompok yang telah memiliki organisasi, (2) Terdapat 2 faktor penghambat terhadap optimalisasi peran kelompok MPA Ma’bulo Sibatang dalam melakukan upaya pengendalian kebakaran hutan dan lahan yaitu faktor internal dan faktor eksternal. Faktor internal antara lain: lemahnya perangkat organisasi, kurangnya jumlah anggota kelompok MPA, serta tidak tersedianya sarana prasarana dalkarhutla pada kelompok MPA Ma’bulo Sibatang. Sedangkan faktor eksternal yaitu belum adanya pembinaan dan pelatihan bagi kelompok MPA, tidak terintegrasinya data anggota kelompok MPA, serta kurangnya dukungan pemerintah desa dan instansi terkait pada kelompok MPA Ma’bulo Sibatang.

ABSTRACTIndonesian National Standard (SNI) No. 8420 of 2018 concerning forest plant seeds is a reference for determining the quality of quality seeds. Technical instructions for assessing the quality of forest plant seeds by Regulation of the Director General of Land Rehabilitation and Social Forestry (RLPS) number P.05/V-SET/2009. Gmelina arborea and Aleurites moluccana seeds are priority seeds for production and use in RHL activities, so research focuses on these two types. The study aimed to determine the quality of Gmelina arborea and Aleurites moluccana seeds produced by the BPDAS-HL Bone Bolango Permanent Nursery. Data collection was carried out by selecting the sample using the Systematic Sampling with Random Start method based on SNI sampling requirements. There were 19,800 Gmelina arborea seeds and 5,900 Aleurites moluccana seeds with a sampling intensity of 0.2%. Testing for Gmelina arborea showed poor results in contrast to Aleurites moluccana in terms of percentage: Media compactness of the two types tested produced a percentage of 100% of the Aleurites moluccana type and 73.5% of the Gmelina arborea type. Seedling height, from the test percentages for both types, produces a percentage of 100%. For seed diameter, the Gmelina arborea test produced a value of 91%, and the Aleurites moluccana type produced a value of 100%. The percentage of leaves for the Gmelina arborea type is 45%, while the percentage for the Aleurites moluccana type is 100%. Average special requirements (RPK), the Gmelina arborea type produces a percentage of 77.37% while the Aleurites moluccana type produces a percentage of 100%. The test results (final score) resulted in 68 Gmelina arborea seedlings that fell into the first criterion (P), 120 in the second criterion (D) and 12 that did not pass the test (X). Meanwhile, the Aleurites moluccana type produces a percentage of 100% which is in the first quality (P).Keywords: Quality Testing; Seedlings; SNI; BPDASHL; Bone-Bolango.

Abstract

The pattern of plant combinations is the arrangement of the species of plants that are cultivated in a field. This research aims to analyze the pattern of plant combinations in the arable land of KTH Sejahtera 4 Tahura Wan Abdul Rachman. The research method used is the multiple plot method, direct observation, and interviews. Plots are arranged systematically on the farmers' arable areas. The total area cultivated by KTH Sejahtera 4 Tahura Wan Abdul Rahcman farmers is 36.05 ha. The area of the sample plots made is 1,442 ha with a sampling intensity (IS) of 4%, therefore the number of plots made is 36 plots. The results showed that all farmers applied agroforestry techniques with mixed crop combinations at random. The combination combines MPTS plants, both from the forestry plant group and the agricultural plant group. From the results of the vegetation analysis, it is known that in KTH Sejahtera's arable land 4 plants that have a high level of dominance are cloves (Eugenia aromaticum L.) and nutmeg (Myristica fragrans). According to farmers' opinion, there are three types of plants that are superior, namely cocoa (Theobroma cacao), rubber (Hevea brasiliensis), and coffee (Coffea robusta L.). The plants favored by the farmers are the mainstay of their income.
