Abstract

The streamflow hydrograph recession curve notes that behavior of the relationship between the aquifer structure and dependencies with the groundwater outflow towards river basin channel. The recession behavior of river basin hydrographs will investigate to understand the hydrology processes of the river basin in the future. This research was conducted with the aim: to analyze the characteristics of the baseflow recession based on the parameters and coefficients of the recession, and the shape of the individual recession curve and the master recession curves both manually and through the processing of genetic algorithms using a linear reservoir model of hydrooffice software package recession curve (RC) 4.0. The results of the visualization of the recession curve shape of the watershed of the research shows there is a very interesting trend in the watershed storage process.The characteristics of the baseflow recession to research watershed with the recession curve slope describe the baseflow recession conditions, especially excellent water storage. The river basin of Keduang have the form of a relatively sloping recession curves, both individual and master recession curve with relatively high recession constant ranged between 0,80 – 0,90 have baseflow recession characteristic is excellent, i.e. the watershed water storage which is the higher volume of water storage.

Abstract

Gmelina moluccana is an Indonesian species of flowering plant native to eastern Indonesia, especially the Moluccas and New Guinea. The people of Maluku widely use this type of wood to make lightweight building materials and boats because it is light and durable. In addition, parts of this species are used as traditional medicine by the community. This study aimed to determine the rate of increase in diameter and height of Titi (Gmelina moluccana) 9 years after planting and to determine the factors that affect the growth of Titi (Gmelina moluccana) 9 years after planting. The method used in this study is a quantitative descriptive method to measure the current annual increment (CAI) and mean annual increment (MAI), followed by a simple linear regression analysis to determine the effect of environmental factors on growth. CAI average nine years diameter 2.51 cm/year, height 1.53 m/year, MAI average nine years diameter 1.94 cm/year, height 1.15 m/year. Environmental factors affecting Titi's growth include soil pH and soil moisture.

Abstract

Development of land cover change in IUPHHK-HA PT. Gema Hutani Lestari is very important to know, so that future patterns of land cover change can be predicted so that negative land cover changes can be prevented or reduced, so that land cover changes that occur can be analyzed. This study aims to access land cover change in the IUPHHK-HA PT. Gema Hutani Lestari between 2013, 2016 and 2018. The methodology used by this study is guided classification with maximum and visual likelihood estimates, spatial data analysis, field checks and using overlays for landsat 8 data in 2013, 2016 and 2018. This study shows that land cover in IUPHHK-HA in Buru Regency, Maluku Province in 2013-2016 changed from forest to open land (69.26%) and from forest to allang-allang (29.03%) dominated by Main Swamp Forest (39.27%), Primary Dry Forest 27.08% and Secondary Swamp Forest ± 17.12%. While the smallest land cover is 0.01% pasture. The largest land cover change occurred in the Secondary Dryland Forest which was reduced ± 693,444 Ha. The most significant change when compared to the situation in 2005 was the Bush Intervention Dryland Agriculture which increased ± 190.69%. Deforestation that occurred was ± 1,122.21 ha (± 160.32 ha / year) and degradation was ± 100.19 ha (± 14.31 ha / year).

Abstract

Kopal merupakan hasil hutan bukan kayu yang dihasilkan dari penyadapan pohon damar (Agathis sp.). Salah satu pemanfaatan kopal yaitu vernis yang merupakan bahan finishing praktis yang dapat langsung diaplikasikan pada permukaan berbagai produk kayu tanpa menggunakan bahan finishing lain. Keunggulan lainnya yaitu nilai estetikanya yang mampu menampilkan keindahan tekstur kayu secara alami. Penelitian ini menggunakan 2 (dua) metode yaitu metode survey dan metode eksperimen. Alat yang digunakan pada penelitian ini adalah : Gelas ukur 250 ml, gelas aiso 240 ml, pengaduk cairan, timbangan, alat giling, phi band, kuas, alat hitung, kamera, wadah penampung dan alat tulis menulis. Dari hasil perhitungan analisa usaha, biaya produksi pembuatan pernis asal negeri Honitetu adalah sebesar Rp. 53,606.00 bila dibandingkan dengan harga pernis komersial sebesar Rp. 60,000.00. Hal ini sangat direkomendasikan karena cukup kompetatif dan memiliki nilai tambah untuk dikembangkan oleh petani pengumpul getah damar, karena pemanfaatan getah damar dapat meningkatkan pendapatan masyarakat namun tergantung dari pemasaran yang tersedia.

Abstract

  Studi keberhasilan pertumbahan tanaman kenari provenan Morela pada kebun benih Provenan Morela di Desa Hatusua Kecamatan Kairatu Kabupaten Seram Bagian Barat”. Skripsi ini membahas tentang keberhasilan pertumbuhan dan kualitas tanaman kenari provenan Morela yang ditanam di desa Hatusua, Kecamatan Kairatu, Kabupaten Seram Bagian Barat. Penelitian ini dilakukan bertujuan untuk mengetahui tingkat keberhasilan tanaman kenari dan faktor-faktor yang mempengaruhi pertumbuhan. Hasil penelitian menunjukan bahwa rata-rata persen tumbuh tanaman kenari hidup mencapai 84% dengan jumlah tanaman hidup sebanyak 336 pohon dan jumlah tanaman mati sebanyak 64 pohon. Tingkat keberhasilan ini lebih dari nilai rata-rata yang di tetapkan oleh Permen LHK No 23 Tahun 2021, yaitu 75%. Selain itu hasil penelitian ini menunjukan bahwa tinggi total dan diameter tanaman kenari pada provenan Morela memiliki variasi yang signifikan, dengan nilai rata-rata tinggi total 1,46 m dan diameter 1,30 cm. Jumlah daun taanaman kenari juga memiliki variasi yang signifikan, dengan nilai rata-rata 10,44 helai daun. Faktor- faktor yang mempengaruhi pertumbuhan tanaman kenari meliputi kondisi dan cara pengangkutan bibit, cara penanman dan pemupukan, kandungan bahan organik dalam tanah, serta kondisi iklim seperti curah hujan. Dalam hal ini, curah hujan yang relatif tinggi pada tahun 2023- 2024 rata-rata berkisar antara 2056 - 667 mm dengan suhu berkisar antara 23,42°C- 32°C, kelembaban udara kisaran 50% - 92%, intesitas cahaya pada provenan kenari berkisar antara 3558 – 11524 lux, pH tanah pada tanaman kenari provenan morela kisaran 6 – 7 netral, dan kelembaban tanah pada tanaman kenari berkisar antara 5 – 8 jumlah air pada tanaman sangat tercukupi. Sehingga dapat disimpulkan bahwa tanaman kenari yang di tanam di lokasi penelitian berada pada kategori berhasil dan memiliki potensi yang baik untuk di kembangkan sebagai tanaman yang produktif dan berkelanjutan.

Abstract

ABSTRACT. The purpose of this study was to determine the height and diameter increment of Titi plant (Gmelina moluccana) 10 years after planting, as well as the environmental factors influencing them. The study method employed a descriptive approach with observational techniques in the field. Data collection involved direct observations in the example II Titi plot (Gmelina moluccana), covering an area of 1 hectare with a planting distance of 3x3. The total number of Titi plant taken in the sample plot was 75 trees. Data analysis utilized quantitative analysis with the mean annual increment, current annual increment, and multiple linear regression analysis methods. The observed environmental variables included soil pH, soil moisture, air temperature, air humidity, and rainfall. The results of the study indicated that the Current Annual Increment (CAI) of diameter in the tenth year was 1.7 (cm/tnm/year), and the Mean Annual Increment (MAI) of diameter was 2.40 (cm/tnm/year). The Current Annual Increment Increment (CAI) of height was 1.99 (m/tnm/year), and the Mean Annual Increment (MAI) of height was 1.62 (m/tnm/year). Factors influencing the growth of Titi plant (Gmelina moluccana) in the Hatusua Seed Source Demonstration Plot were soil pH and soil moisture.
