KERUSAKAN TIPE EKOSISTEM KARST DAN PENGARUHNYA TERHADAP PERUBAHAN IKLIM (SUATU PENDEKATAN TEORI) The Damage of Karst Ecosystem and Its Impact on The Climate Change (a theoretical approach)Benteng. H SihombingFakultas Kehutanan, Universitas MulawarmanSamarinda ABSTRACTKarst ecosystem poses high economic potency however its attention was lack due to to date only pay attentions merely on mineral resource potency, and its conservation measure only focus to some extent on cave. Mean while, karst area owns wider protective function, such as water conservation, state revenue from tourism, mining, bird nest, even it closely relates to the national security issue and state intelligence. Pay an attention on karst ecosystem that covers biotic potency and mineral energy exploration is tought to be far from seriousness meanwhile its tension on this ecosystem tends to be larger, even already comes to the stage of ecology endanger. In relation to the global temperature rise that leads to the climate change, natural karst ecosystem seems pay a big role in reducing carbondioxide through karstifikasi process. Therefore, the karst ecosystem conservation is an urgent agenda.Key words : Karst, Ecosystem, Climate change.

Abstract

Objectives of the research were to study the effect of Green-Tama fertilizer and Atonik plant regulator, as well as their interaction on the growth and production of tomato; and to find proper dosage of Green-Tama fertilizer and proper consentration of Atonik plant regulator for better growth and production of tomato.The Completely Randomised Design was employed for this research with factorial 3 x 3 and 3 replications.  The first factor was Green-Tama fertilizer dosage (K), consisted of 3 sub factors: no Green-Tama fertilizer application (k0), 2 ml l-1 water (k1), and 3 ml l-1 water (k2). And the second factor was Atonik plant regulator concentration (P) that consisted of 3 sub-factors: no Atonik plant regulator application (p0), 1 ml l-1 water (p1, and 2 ml l-1 water (p2).Results of the research revealed that:1. The Green-Tama fertilizer affected very significantly on the plant height at 4 weeks after sowing, days of crop firstly flowered and weight per fruit, affected significantly on plant height at 6 weeks after sowing, and did not affect significantly on plant height at 8 weeks after sowing and number of fruit per crop;2. The Atonik plant regulator concentration affected very significantly on the plant height at 4, 6, and 8 weeks after sowing, days of crop firstly flowered, number of fruit per crop, and fruit weight per crop, and did not affect significantly on plant height at 2 weeks after sowing;  and3. The interaction between those two factors did not affect significantly on all parameters observed.

Abstract

The purpose of this research is to know the effect of petroganic fertilizer and growmore fertilizer and its interaction on growth and yield of cayenne pepper. The research method used Randomized Complete Design (RAL) in factorial 4 x 3, and replication 5 times, consisting of 2 research factors. Factor I is Petroganic fertilizer (P), consists of 4 levels, namely: (p0) without fertilizer Petroganik (control), (p1) Petroganic fertilizer dosage 1 ton / ha equivalent 42 g / plant, (p2) dose of 2 tons Petroganik fertilizer / ha equivalent 84 g / plant and (p3) Petroganic fertilizer dose 3 ton / ha equal to 120 g / plant. Factor II is Growmore fertilizer (D) consisting of 3 levels ie: (d0) without Growmore fertilizer concentration, (d1) Growmore fertilizer concentration 2 g / l.air and (d2) Growmore fertilizer concentration 4 g / l. water.The results showed that the treatment of Petroganik fertilizer significantly affected the age of flowering. Very significant effect on plant height aged 15 days, age 30 days, age 45 days after planting, harvest age, number of fruit per plant and weight of fruit per plant. The weight of the heaviest fruit was found in the p3 treatment of 184.33 g / plant, while the lightest fruit weight was found in the treatment of p0 86.53 g / plant. Growmore fertilizer treatment has no significant effect on plant height age 45 days, flowering age, harvest age and number of fruit per plant. Significant effect on the weight of fruit per plant. Very significant effect on plant height. Interaction treatment of fertilizer Petroganik and fertilizer Growmore very significant effect on plant height, flowering age, harvest age, number of fruit and fruit weight per plant.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi  faktor  penyebab  kebakaran  lahan di  Desa Purwajaya Kecamatan Loa Janan Kalimantan Timur dan untuk memberi rekomendasi terhadap kegiatan pengendalian kebakaran hutan yang akan dilakukan. Penelitian ini diharapkan dapat memberi gambaran langsung dan tidak langsung mengenai faktor utama penyebab kebakaran hutan, yang nantinya dapat dimanfaatkan oleh berbagai pihak terkait seperti peneliti, akademisi kehutanan dan  akademisi  non  kehutanan.  Sehingga  dapat  menjadi  dasar  acuan  dalam kegiatan pengendalian kebakaran hutan di Desa Purwajaya Kecamatan Loa Janan Kalimantan TimurPengumpulan data primer dilakukan dengan menggunakan metode wawancara terhadap petugas, Satgasdamkar dan masyarakat sekitar hutan serta metode observasi langsung di lapangan. Sedangkan untuk pengumpulan data sekunder dilakukan dengan menggunakan metode penelusuran dokumen, agar didapatkan berbagai dokumen yang berkaitan dengan upaya pengendalian yang dilakukan dan kejadian kebakaran hutan di Wilayah Desa Purwajaya Kecamatan Loa Janan. Pengambilan responden wawancara dipilih secara sengaja (purposif) dan dalam jumlah yang kecil. Hal tersebut sesuai dengan pendapat Sitorus (1998) bahwa dalam penelitian kualitatif, pemilihan sampel penelitian tidak mengutamakan patokan keterwakilan populasi, melainkan keterwakilan aspek permasalahan, sehingga sebagai implikasinya sampel harus dipilih secara sengaja (purposif) dan dalam jumlah yang kecil, sehingga jumlah responden adalah 1 orang Kepala Damkar dan 6 orang ketua regu pemadam kebakaran 10 orang masyarakat setempat.Dari hasil penelitian ini dapat disimpulkan bahwa faktor-faktor penyebab kebakaran lahan di  Desa Purwajaya Kecamatan Loa Janan Kalimantan Timur yang disebabkan oleh faktor Alam  (bahan bakar, topografi lahan, hidrologi, cuaca, iklim, dan rambu-rambu kebakaran) dan Faktor Manusia (kelalaian dan  ketidak pedulian masyarakat.Kegiatan pengendalian kebakaran hutan yang dilakukan oleh pihak yang terkait yakni Dinas Kehutanan harus mampu meningkatkan beberapa kegiatan, seperti pencegahan kebakaran, pada saat Kebakaran (Pemadaman Kebakaran) dan Pasca Kebakaran.
