Abstract

This research is aimed to comprehend the agroforestry land use pattern dynamics and composer components of Mutis Timau protected forest, and was held at Fatukoto and Ius Mollo village of Mollo Utara Subdistrict of Timor Tengah Selatan Regency of East Nusa Tenggara Province in January until April 2014. The primary data of the pattern was collected through observation and analyzed by grouping while the composer components through direct measurements and analyzed by calculation of volume, Shannon-Wiener biodiversity index, and stand projection with Sexy-fs tool. The stand kind and age secondary data were from the Forestry Agency of TTS Regency. The pattern dinamics were agrosilvopastural utilization at the young stand and livestock grazing silvopastural at the medium and old age stand. Young stand was combined with greenery food plants, while medium with graze and fruit crops plants, and the old one without combination practice. The composer components consisted of 20 kind and total 16,128 species and 1,709.12 m3of volume, which comprised with 11,976 species and 12 m3wooden vegetation of the young, medium 3,963 and 380,16 m3, and the old 189 species and 1316,96 m3.

Abstract

ABSTRACTThis research is aimed to study the contamination level of Gelaran Cajuput Oil Plant wastewater, to obtain the design of the treatment site plan, and to recommend the determination of the site plan location. The phases covered pilot field survey to determine the location, measuring the volume and collecting the sample, analizing the process and deciding the treatment system. The results showed the contamination level parameters were acid pH, and high BOD and COD. The appropriate length, width, and depth of chamber units’ dimension and specifications of the treatment yielded were respectively as follows: a) 1.5 m, 1.0 m, and 1.0 m of equalisation; b) 1.5 m, 1.0 m, and 1.0 m of neutralization; c) 1.25 m, 1.06 m, and 1.25 m of anaerobic hybrid reactor; d) 1.5 m, 1.0 m, and 1.0 m of stabilization, and was located on downward to facilitate the effluent flowing by gravitational force merely. Key Words:  Cajuput oil, waste water treatment, site plan, anaerobic hybrid reactor

Abstract

This research was conducted in order to understand the potential of landslide hazards in the Manikin Watershed and to map the slide hazards so that they can be used as a reference in conducting landslide disaster mitigation. The method used was scoring which was based on the Regulation of Minister of Public Works Number 22 /PRT/M/2007 about Guidelines for Spatial Planning for Landslide Disaster Prone Areas, and the parameter used were soil type, geological formation, rainfall, land use, and slopes. The results of the research showed that the landslide potential in the Manikin Watershed is dominated by Low Landslide Class which is 6,924.703 Ha in the area or 54.912 %. The next is the Medium Landslide Class which covers an area of 3,881.911 Ha or 30.783%, the High Landslide Class covers an area of 1,758.058 Ha or 13.941%, and the Very High Landslide Class covers an area of 45.96 Ha or 0.364%.  Keywords: Mapping, Landslide, Manikin Watershed, Geographic Information System (GIS)

Abstract

ABSTRAKKualitas bibit Kayu Putih sangat ditentukan oleh media kecambah sebagai salah satu faktor utama pertumbuhan benih kayu putih. Namun informasi mengenai media kecambah yang baik untuk mendukung perkecambahan benih kayu putih masih sangat terbatas. Penelitian ini bertujuan untuk mengevaluasi vigoritas benih kayu putih pada berbagai media kecambah. Penelitian ini dilaksanakan dari bulan Juli-Agustus 2025, di Kompleks Perumahan Pondok Indah Matani Kupang, Nusa Tenggara Timur. Penelitian ini menggunakan RAL yang terdiri dari 5 perlakuan yaitu pasir, tanah, bokashi, kasgot dan kompos limbah baglog jamur tiram. Pengulangan dilakukan sebanyak 5 kali pada setiap perlakuan dengan menggunakan 10mg benih. Nilai indeks vigor, keserempakan tumbuh benih dan kecepatan tumbuh benih, dihitung sebagai data pengamatan. Analisis data menghasilkan media kecambah secara signifikan berpengaruh terhadap vigoritas benih kayu putih. Media terbaik adalah tanah yang mampu meningkatkan indeks vigor sebesar 54,50% dan keserempakan tumbuh benih sebesar (72,50%) dibanding media lainnya, juga kecepatan tumbuh benih tertinggi 0,77%/hari.Kata kunci: Kayu putih, Media kecambah, Perkecambahan, Vigoritas benih.
