Abstract

The purpose of this study is to identify types of dominant vegetations in the plantation area and former farmland as indicator of soil fertility. Vegetation plays an important role to provide soil fertilities. Certain types, growing in the former farmland can possibly indicate soil fertilities both in the plantation area and former farmland. Aspect of the fertilities likely influences number of vegetative types and diversity of species. Measured vegetation is used to comparing species composition and its diversities. The former plantation that is taken up as sample has been used for 5 year. Identification of the type was carried out by using vegetative analysis. The valuable index was calculated to determine extensively the role of the dominant types from seeding and wooded phase. There are four different plot sizes. 20x20 meter is utilized purposively for wooded phase, 10x10 meter is pole, 5x5 is used as stake phase and 2x2 meter is made for seeding phase. The species which has important role for the soil fertilities are indentified through exploring various references and the result of interview from local society The finding reveals that vegetative composition in the former farmland which has been used for 5 year consists of three phases, including seeding, stake and pole. Totally, the types are 30 species under each phase. 23 types are in the seeding, 19 types contribute for pole and 6 types are resulted in the wooded phase. The dominant type of seedling phase is Lunasia amara, Piper aduncum is gotten in the stake phase, and the pole one is Mallotus philippensis. However, differently the plantation area carried out 39 species in the seeding phase, sapling phases has 36 species, pole phase carries out 16 species and 17 species is in the wooden phase. The dominant types is in the seeding and stake phase is Nephelium lappaceum, Lansium domesticum is pole phase, and Durio zibenthinus is resulted in the wooded phase

Abstract

Protected forests have drawn international attention.  This research aims to determine scenarios of land-use change in Protected Forest of Wosi Rendani (PFWR).  The study was conducted using land evaluation approach to land unit, determination and alternative land use change, based on the potential and the level of threat for PFWR.  The results showed that PFWR should remain as a protected forest although the total score of forest modeling was 130. This forest serves to protect soil, water, and danger from floods and landslides. This region has springs, caves, and waterfalls, which can be further developed into eco-tourism and environmental services. As a city forest, PFWR makes Manokwari's weather cooler, enhances the quality of air, reduces environmental pollution, and adds catchment areas. As a community forest, PFWR has forest plants, agricultural crops and fruits, in which people are only allowed to take flowers, fruits, and seeds they have planted. As a buffer zone, PFWR serves as a buffer to reduce population pressures on the forest area or village surrounding the area with high interaction by integrating conservation and economic interests of the surrounding community. As cultivation and settlement, PFWR has three settlements, namely Soribo, Kentestar, and Ipingoisi, 4 settlements outside PFWR namely Tanah Merah Indah, Ajoi, Buton, Mako Brimob, as well as plots of land owned by developers such as Bank Arfindo, Lumintu, Irman Jaya, and Suntari. The final scenario of the land use change in PFWR depends on the policy of local and central government.

Abstract

Aspects of litter productivity in fallow land in Manokwari, Western Papua need to be investigated because litter has the potential to increase soil fertility. The objective of this research was to count and estimate litter productivity in 15 years-fallow land in Womnowi, Sidey District, Manokwari. We used litter trap of 1 m2 in size with 2 mm mesh size. Nine litter traps were set under tree species, three replications of each tree species which have higher Important Value Index (IVI). Litters were weekly taken and oven dried until reaching the constant mass. Result showed that the dry masses of litters are not significantly different among three species. If the productivities are constant and probabilities of litterfall are same, the estimates of Dractontomelon dao have dry mass productivity rate (DMP) reaching 10.32 ton ha-1 year-1, followed by 8.98 ton ha-1 year-1 for Pometia pinnata, and 7.96 ton ha-1 year-1 for Octomeles sumatrana. Dry mass percentage (DMP) decreased in the order of P. pinnata > D. dao > O. sumatrana. We found negative linear regressions about water content of litter (WCL) and DMP at P. pinnata and O. sumatrana, but not for D. dao. These negative linear regressions can be used to estimate the rate of decomposition of each species. Keywords: linear regression, litterfall, secondary forest, soil fertility, Western Papua

Abstract

Limpasan permukaan dan sedimen seringkali diremehkan dalam upaya mitigasi banjir. Padahal keduanya jika dalam jumlah besar akan menyebabkan pedangkalan dan meluapnya air sungai yang berdampak banjir. Penelitian ini bertujuan untuk menentukan pengaruh limpasan permukaan dan sedimen terhadap curah hujan dengan analisis regresi sederhana SPSS 17. Hasil penelitian menunjukan hubungan antara curah hujan dengan aliran permukaan hanya penggunaan lahan sebagai tegalan yang signifikan, sementara penggunaan lain tidak signifikan, dilanjutkan uji linieritas menujukan garis linier. Hasil uji signifikansi korelasi/keeratan tidak menunjukan korelasi (sangat lemah) hanya pada penggunaan lahan sebagai tegalan yang menunjukan korelasi yang cukup erat. Sementara hubungan antara curah hujan dengan sedimen menunjukan hubungan yang tidak signifikan, dilanjutkan uji signifikansi korelasi tidak menunjukan korelasi (sangat lemah). Pada lima penggunaan lahan hubungan keeratan curah hujan dengan limpasan permukaan menunjukan semua tidak ada hubungan /hubungan sangat lemah. Dengan demikian semakin meningkatnya curah hujan tidak selalu meningkatkan sedimen. Hanya penggunaan lahan sebagai perkebunan kelapa sawit yang mengalami penambahan luas. Penurunan luas hutan diduga peningkatan perambahan liar pada hutan produksi terbatas yang berada disekitar perkebunan kelapa sawit.

Abstract

Tujuan penelitian ini adalah untuk mengukur produktivitas serasah basah dari vegetasi dominan bergantung pada suhu dan kelembaban relatif di lahan bera Womnowi Distrik Sidey Manokwari. Kami menggunakan perangkap serasah berukuran 1 m x 1 m dari mesh 25 cm2 -1 dan dipasang selama bulan Maret hingga Mei 2018. Setiap minggu serasah diambil dan ditimbang di lapangan, selanjutnya diukur suhu dan kelembaban relatif di tiga titik berbeda. Analisis data menggunakan Ms. Excel 2007 dan SPSS 23.0 untuk menginterpretasikan data. Produktivitas serasah basah dapat diinterpolasikan dengan suhu dan kelembaban relatif, sehingga menjelaskan kontrol faktor lingkungan. Berdasarkan uji beda nyata terkecil (BNT) 5% tiga jenis vegetasi dominan memiliki rerata produktivitas serasah: Pometia pinnata Forst. & Forst. 24.59 ± 17.01 g m2 -1 minggu-1, Dracontomelon dao (Blanco.) Merr. et Rolfe. 42.09 ± 19.17 g m2 -1 minggu-1, dan Octomeles sumatrana Miq. 40.14 ± 15.28 g m2 -1 minggu-1 berbeda signifikan. Meskipun penelitian ini hanya berlangsung selama 12 minggu, model produktivitas serasah basah dapat digunakan untuk menduga produktivitas serasah per tahun. Produktivitas serasah basah merupakan salah satu ‘proses alami’, akan tetapi memiliki peran yang signifikan pada: kimia tanah, penahan air tanah, konservasi tanah, dan dapat digunakan untuk menentukan produktivitas lahan bera.

Abstract

Protected forests play an important role in supporting human life, protecting land and water and preventing the dangers of flooding and landslides, but a lot of conversions have taken place today. Research-based on techniques for observation, interviews, and case studies. Measurement of respondents' perceptions and attitudes is carried out using instruments in the form of questionnaires that refer to the Likert scale. Data analysis was performed descriptively to describe the level of perception, attitude with simple non parametric linear regression. Maruni protected forest has the potential of limestone with 11 mineral elements, 5 of which are the largest Ca (93.62%), Si (2.45%), Mg (1.58%), Al (0.97%) ) and K (0.47%). This forest allows conversion area, from an area of ​​969.84 ha with limestone potential of only 250 ha (25.78%), another 719.84 ha (74.22%) can still be designated as a protected forest. The public perception of conversion to cement mining was 59.03% negative, 14.83% neutral and 26.12% positive. While the attitudes of the community 43.1% accept, 38.94% neutral and 47.92% reject the conversion to become cement mining. The community hopes that there will be economic improvement, community empowerment and employment, especially affected communities.

Abstract

The conservation status of vegetation in coastal forest needs to be explored, because coastal forests are an area of development in the future. This study aims to compare coastal forest vegetation (A areas) with vegetation in habitats 600 meters from the shoreline (B areas) referring to the International Union for Conservation of Nature Resources (IUCN) conservation status. The method used the analysis of vegetation technique for determining the important value index (IVI), then each component of the IVI data is compared through the one way ANOVA test followed low significantly different test (LSD) at the P<0.05. The result showed that IVI components of vegetation in A areas belonging to the IUCN category were higher then vegetation in B areas. The vegetation in A areas categorized as IUCN was: Pongamia pinnata (L.) Pierre., Celtis philippensis Blanco., Intsia bijuga (Colebr.) Kuntze., Polyscias nodosa (Blume.) Seem., and Calophyllum inophyllum L., while in the types B areas in the IUCN category were dominated by Spathiostemon javensis Blume., Horsfieldia irya (Gaertn.) Warb., and Myristica fatua subsp. fatua. Vegetation of coastal forest needs to be prioritized as a conservation area, because species belonging to the IUCN category have high IVI.

Abstract

Abstrak: Selama proses suksesi, vegetasi merupakan satu dari komponen utama untuk meningkatkan kesuburan tanah. Tujuan penelitian ini adalah untuk menganalisis dan mendeskripsikan peran vegetasi dominan pada karakteristik tanah di lahan bera berumur 15 tahun Kampung Womnowi, Distrik Sidey, Manokwari. Vegetasi dominan ditentukan berdasarkan data indeks nilai penting (INP) analisis vegetasi. Sampel tanah diambil secara komposit pada luasan lahan 1 hektar dari dua kedalaman tanah (0–10 cm dan 10–20 cm). Vegetasi yang mendominasi lahan bera secara berurutan adalah Pometia pinnata, Dracontomelon dao, Octomeles sumatrana, Lansium domesticum, dan Pimelodendron amboinicum. Kehadiran O. sumatrana mengindikasikan lahan bera tanah aluvial, lebih lanjut terbukti karena lahan bera tersebut berdekatan dengan Sungai Womnowi. Karakteristik fisik tanah didominasi oleh fraksi lempung dan unsur makro lebih tinggi pada kedalaman 0–10 cm dibanding kedalaman 10–20 cm. Karakteristik tanah menunjukkan bahwa tanah tergolong masam (pH 5.4–5.6), kadar karbon organik tanah sedang (1.07–3.39%), kadar nitrogen total rendah (0.17–0.53%), kadar fosfor tersedia tergolong tinggi (10.7–22.4 ppm), kapasitas tukar kation (KTK) tergolong tinggi (10.50–20.32 cmol kg-1), kejenuhan basa tergolong sangat tinggi (65.4–66.7%), dan kadar Al3+ and H+ sangat rendah. Secara keseluruhan urutan KTK menunjukkan Ca > Mg > Na > K yang mengonfirmasi tanah aluvial dan pencucian kalium terjadi dengan cepat. Rendahnya kadar kalium dapat dihubungkan dengan penggunaan unsur tersebut untuk pembentukan buah L. domesticum. Selama pemberaan 15 tahun, vegetasi dominan memengaruhi karakteristik tanah.Kata kunci: vegetasi pohon, kesuburan tanah, analisis tanah, aluvial, Papua BaratAbstract: During succesional season vegetation is one of major compound to increase soil fertility. The purpose of this study was to analyzed and description dominant vegetation and their contribution to soil characteristic at fallow land 15 years old Womnowi Village, Sidey District, Manokwari. To determine dominant vegetations we used data important value index (IVI) of vegetation. Two depth of sample soils (0–10 cm dan 10–20 cm) were taken from one hectare area by composite technique. The dominant vegetation on fallow land dominated by Pometia pinnata, Dracontomelon dao, Octomeles sumatrana, Lansium domesticum, and Pimelodendron amboinicum respectively. Presence of O. sumatrana was indicated that the type of aluvial fallow land, further it is proven because the fallow land is close to the Womnowi River. Soil physical characteristic dominated by clay fractions, macronutrient was higher in depth 0-10 cm than 10-20 cm. Characteristic of soil shows acidic soils (pH 5.4–5.6), moderate of soil organic carbon (1.07–3.39%), total of nitrogen was low (0.17–0.53%), high available phosphorus (10.7–22.4 ppm), moderate cation exchange capacity (CEC) (10.50–20.32 cmol kg-1), very high base saturation (65.4–66.7%), and very lows of Al3+ and H+. Overall the order of CEC shows Ca > Mg > Na > K respectively confirmed aluvial soil and fast leached potassium in soil. Low potassium levels are thought be related to the use of the element for fruits formation of L. domesticum. During 15 year fallowed, dominant vegetation had influence to soil characteristic.Key words: tree vegetation, soil fertility, soil analysis, alluvial, West Papua
