Abstract

Abstract Land cover type is a factor that needs to be taken into account in an effort to rehabilitate a watershed as it can affect planting activities, resulting in varying use of working time.  Nevertheless, technical instructions applied to reforestation are still general. Therefore there is a need for a standard working time in reforestation (planting) as a guideline in determining policies in planting activities. This research was conducted in Bantik Village, Bolaang Timur District, Bolaang Mongondow Regency during one month. to analyze the work performance of planting on several types of land cover. The study used repetitive timing for data collection method which is then analyzed and furtherly tested with ANOVA. The results showed that land cover has a significant effect on work performance, the work performance of planting on young shrub land cover has the highest achievement of 16 seeds per hour followed by an old shrub of 15 seeds per hour and bush of 12 seeds per hour. Keywords: Work performance, plantation, land cover

Abstract

Taman Wisata Alam (TWA) Batuputih memiliki potensi wisata alam yang bagus, namun tidak banyak masyarakat sekitar yang mengambil peluang usaha, ataupun melakukan kegiatan-kegiatan yang dapat meningkatkan pendapatan. Penelitian ini bertujuan untuk mengukur tingkat efektivitas pengelolaan TWA Batuputih dan menganalisa dampak pengelolaan TWA Batuputih terhadap pendapatan rumah tangga masyarakat sekitar. Metode untuk mengukur tingkat efektivitas metode METT (Management Effectiveness Tracking Tools), dan uji beda yang membandingkan antara pendapatan masyarakat yang aktif dan tidak aktif dalam wisata alam. Hasil penelitian menunjukkan tingkat Efektivitas pengelolaan TWA Batuputih termasuk dalam kategori cukup efektif. Dampak dari pengelolaan ini terhadap nilai ekonomi khususnya peningkatan pendapatan masyarakat sekitar ternyata masih belum dirasakan terbukti dengan dilakukannya uji beda pendapatan masyarakat yang aktif dan tidak aktif dalam wisata alam hasilnya tidak berbeda nyata. Sebaiknya pengelola perlu melakukan penambahan fasilitas wisata alam, penguatan kelembagaan pengelolaan TWA Batuputih, penerapan konsep pengelolaan kolaboratif, serta melakukan pendekatan dan koordinasi dengan pemerintah daerah dan masyarakat sekitar agar mendukung konsep pariwisata yang berkelanjutan.   Kata kunci : pengelolaan taman wisata alam, pendapatan masyarakat sekitar, batuputih

ABSTRACTThe objective of this study is to develop Tangkoko - Duasudara Nature Reserves management blocks using Geographic Information Systems approach. The overlaying methods of thematic maps were used to blend land cover, elevation, slope, and distribution of wildlife species. Social data included demographic data in the surrounding area of Tangkoko - Duasudara Nature Reserves. Management block criteria and scoring refer to Peraturan Pemerintah Tentang Tata Hutan dan Penyusunan Rencana Pengelolaan Hutan, Pemanfaatan Hutan dan Penggunaan Kawasan.The result showed that Tangkoko - Duasudara Nature Reserves are divided into three blocks, namely Restoration/Rehabilitation Blocks (1724.29 ha; 23,22%), Jungle Blocks (4.251,41 ha; 57,26%), and Core Blocks (1449,30 ha; 19,52%). Restoration/rehabilitation blocks are spread into five places and physically characterized by moderate slope, medium altitude and low species density. Land cover is dominated by open land and agriculture. Jungle Block are spread into three places and characterized by plane to medium altitude and high species density. Secondary forest is the dominant land cover. The Core Blocks are spread into two places and characterized by steep slopes, high altitude, high species density. The land cover is dominated by secondary forests.

Abstract

ABSTRACT The most of natural Indonesia area is dominated by water teritorial which consist of thousands of island with souronded by mangrove. Functions and benefits of mangroves have been widely known, both as a place of spawning fish in the waters, land protector of abrasion due to waves, winds from the mainland protector, filter sea water intrusion inland and content of heavy metals that are harmful to life, a haven of migratory birds, and as wildlife habitat and other direct benefits for humans. The purpose of this research is aimed to analyze the structure and composition of mangrove vegetation found in the District Likupang, North Minahasa Regency, North Sulawesi. This research was conducted using the transect method and terraced path, by surveying observations and direct measurements in the field and then analyzed descriptively. The collected data are presented in tables and graphs. The results showed that the structure of mangrove forests Likupang for seedling phase dominated by Sonneratia sp, for the sapling phase is dominated by Avicennia alba and to phase dominated by Sonneratia sp while for there phase dominated by Sonneratia sp and mangrove forest composition Likupang are dominated by Sonneratia sp followed by the type Rhizopora sp., and Bruguera sp.  Key words: Forest Mangrove, Mangrove types, structure and composition of the Mangrove

Abstract

ABSTRACTThis research is aimed to study the phenology of angsana trees in the urban areas of Manado city. Sam Ratulangi street is divided into five observing segments with relatively the same number of trees at about 129-131 at each segment giving a total of 651 trees. The phenology observed at each tree including leaf, flower, and fruit phenomenon. The diameter of each tree are measured. Trees were then greuped into five categories:<10, 10-<20, 20-<30, 30-<40 and ≥40 cm. The results shows that angsana trees in Sam Ratulangi street had diameter of about 3.4-50.5 cm.The highest accumulation at trees was at last fourth categories ranging at 132-185 trunks. The phenology of leaves which dominate the entire segments on Sam Ratulangi street are green leaves at 89.9%of the 651 trees.The shoot phenology was performed by 11-20 trees (1.7-3.1%) and the flowering phenomena were found in 17-20 trees (2.6-3.8%). The flowering phenomena was mostly found at segment 1 (zero point) and becoming less and less toward the upper segments (Citraland intersection). The fruiting phenology shows and an opposite trend. The new flowering phenology are found on trees in three categories at medium diameters (10-40 cm) while the phenology of fruiting are found on trees with large diameters (>20 cm).

Abstract

ABSTRAK Angsana merupakan jenis tanaman penghasil kayu berkualitas tinggi dari suku Fabales, kayunya tergolong keras dan berat. Penurunan kualitas lingkungan perkotaan ditandai dengan semakin meningkatnya pencemaran udara yang dihasilkan oleh kendaraan bermotor, limbah rumah tangga, dan aktivitas industri yang mengemisikan gas-gas seperti CO2 dan gas NOx di samping bentuk-bentuk polutan lainnya. Hal-hal tersebut dapat memperburuk dampak pemanasan global. Penelitian ini dilakukan untuk menaksir biomassa guna mengetahui kandungan karbon (C) dari jenis angsana (Pterocarpus indicus Willd) pada sisi kiri jalur penghijauan Jalan Sam Ratulangi dan Jalan Toar, Kota Manado. Penghitungan biomassa angsana menggunakan persamaan allometrik untuk hutan atau tumbuhan tropika lembab yang terdiri dari dua peubah bebas, (AGB = α + β1 (ln (DBH)2× H). Hasil pendugaan biomassa tanaman angsana menunjukkan rata-rata biomassa di jalur penghijauan Jalan Sam Ratulangi dan Jalan Toar masing-masing sebesar 252,12 kg, dan 230,93 kg. Kandungan karbon tersimpan pada kedua jalur penghijauan masing-masing sebesar 126,06 kg, dan 115,46 kg.Kata kuci : Pemanasan global, biomassa, karbon, metode non-destructive sampling, persamaan allometrik, Pterocarpus indicus Willd
