Abstract

Abstrak                                                      Masalah penyadapan getah pinus yang selama ini dilakukan di daerah Simalungun belum banyak dikaji apakah produktivitanya sudah memenuhi harapan atau bahkan melanggar aturan yang berlaku.Telah dilakukan penelitian yang bertujuan untuk mengetahui produktivitas penyadapan getah pinus dan kaitannya dengan kelestarian hutan dan hasil hutan khususnya di desa Parhottingan, Aek Nauli Wiayah KPH II Kabuapten Simalungun.Penelitian ini dilaksanakan dengan mengukur 30 batang pohon pinus yang akan disadap dan diukur produksi per pohon dan perkoakan sadapan dan dibuat plot seluas 1 ha untuk mengukur kesesuaian jumlah koakan nyata yang dilaksanakan oleh petani penyadap secara nyata dan dikaitkan dengan implementasi peraturan yang berlaku untu penyadapan getah pinus.Hasil penelitian memperlihatkan bahwa produktivitas penyadapan getah pinus per koakan adalah 277,8 g dari pohon pinus yang berdiameter rata-rata 57,7 cm dan jumlah koakan rata-rata 5,8 (6 koakan) per batang. Dari 170 pohon sampel pewakil, hanya 42 pohon (24,71 %) yang disadap dengan jumlah koakan yang sesuai dengan aturan yang berlaku dan 128 pohon (75,29 %) lagi disadap dengan tidak memuhi aturan yang berlaku sehingga dapat dipastikan ada ancaman kelestarian hutan dan hasil hutan yang sedang dilakukan penyadapan getah pinus di desa Parhottingan, Kabupaten Simalungun.

Abstract

Kuli Village , Lobalain District , Rote Ndao Regency has a relatively natural mangrove forest ecosystem. For the people of Kuli Village, the existence of mangrove forests which are very important as a support for their lives directly and indirectly has been felt by the people of Kuli Village. The most worrying thing about the destruction of mangrove forests is the loss of mangrove species which causes a decrease in the species diversity of mangrove forests. The purpose of this study was to identify the types of mangroves in the Coastal Area of Kuli Village, Lobalain District, Rote Ndao Regency, East Nusa Tenggara Province.This research was conducted in Kuli Village, Lobalain District, Rote Ndao Regency, East Nusa Tenggara Province .The determination of the measuring plot is done in a simple random sampling manner. The data collection techniques used in this study are primary data and secondary data. From the data collected, descriptive and quantitative data analysis was carried out. The results of the study obtained that there are 6 types of mangroves that grow, namely Perepat (Soneratia alba), Mangrove (Rizhopora apiculata), Pedada (Sonneratia caseolaris), White mangrove (Bruguiera cylindrica), Fire-fire (Avicennia marina) and Black Flames (Avicennia alba). The diversity index (H') of all types was obtained at 1.352. This shows that the level of diversity of mangrove species in Kuli Village is included in the moderate category .

Abstract

Betung bamboo is widely used for building construction materials, furniture, and has ecological benefits because it is hard and strong. Bamboo propagation can be done generatively and vegetatively. Generative propagation has weaknesses, namely bamboo seeds are very difficult to obtain, seed viability is low, seeds cannot be stored for long, are susceptible to pests and diseases, and require a very long time to reach the age of the first harvest. Regulatory substances that can be used to encourage the growth of bamboo branch cuttings are shallots and banana weevils. The study was arranged in a completely randomized design (CRD) with 9 treatments namely A0 (control), A1 (25% banana weevil), A2 (50% banana weevil), A3 (75% banana weevil). banana), A4 (100% banana weevil), A5 (25% shallot), A6 (50% shallot), A7 (75% shallot), A8 (100% shallot). The results showed that natural ZPT (banana and shallot weevils) had no significant effect on the growth of betung bamboo branch cuttings. Although no treatment had a significant effect, when viewed from the average value of each parameter, it can be said that the treatment of natural ZPT concentrations on bamboo betung branch cuttings was in treatment A8 (100% shallot concentration) for the parameter of the period of shoot emergence, treatment A6 (50% shallot concentration) for the number of leaves parameter, treatment A0 (control) for the root length parameter and for the parameter living percentage of bamboo betung branch cuttings showed the highest average for all treatments.
