Abstract

Asam humat adalah salah satu senyawa yang terkandung dalam senyawa humat, yang merupakan hasil dekomposisi bahan organik, terutama bahan nabati yang terdapat dalam batubara muda, gambut, kompos atau humus. Salah satu karakteristik yang paling khusus dari senyawa humat ialah kemampuannya untuk berinteraksi dengan ion logam, oksida, mineral, dan senyawa organik, termasuk pencemar beracun, dengan membentuk asosiasi, baik yang larut dalam air maupun yang tidak larut dalam air. Telah dilakukan isolasi dan karakterisasi asam humat serta penentuan sifat fisik dan kimia tanah hutan asal Desa Waai dan Desa Airlouw, Pulau Ambon serta Desa Kairatu, Pulau Seram. Isolasi asam humat dilakukan menggunakan metode ekstraksi alkali. Hasil penelitian menunjukkan bahwa asam humat hasil isolasi dari ketiga lokasi mengandung gugus fungsi yang sama, yaitu asam karboksilat dan hidroksil (–OH) fenolat. Kadar asam humat tertinggi terdapat pada Desa Kairatu, yaitu 42,05%.

Abstract

Morphometry is important characteristics to understand hydrological processes of a catchment.The research purpose was to study  the morphometry and flood discharge characteristics of the Way Apu Watershed. Morphometrics data were measured using topographic maps and SIG-ArcView. The frequency distribution of rain was calculted using the Log-Pearson Type III, Gumbel, Normal, Log-Normal methods, and the design rainfall was determined according to 2, 5, 10, 25, 50, and 100 years return periods. The flood discharge was calculated using the rational method, while the hydrograph unit was established using the Nakayasu method. The result showed that the watershed roundness ratio is 0.46 and the elongated ratio is 0.86 indicating the elongate watershed form. The design Rainfall of the return periods of 2, 5, 10, 20, 25, 50 and 100 years range from 37.59 - 185.14 mm (Log Pearson Type III), 41.32 - 180.28 mm (Gumbel), 47, 68 - 139,98 mm (Normal), and 36,82 - 203,66 mm (Log-Normal). The Smornov-Kolmogorof test results show that the Log-Pearson Type III, Gumbel, and Log-Normal methods are suitable to calculate the design flood discharge. Data of the design flood discharge of Gumbel is suited for 25 years of waterwork plan, while Log-normal is suited for 100 years plan. Based on the Nakayasu Synthetic Hydrograph Unit, the river capacity of the Way Apu watershed is 21.37 m3/sec.

Abstract

Study on assessment carrying capacity of food, especially rice to ensure food security was conducted in the Kei Besar Islands, Southeast Maluku Regency. The results showed that district of Kei Besar has ability to food self-sufficient and to provide a proper life for its community in Northwest and Southwest Kei Besar. While, district of South Kei Besar is able to be self-sufficiency in food but has not able to provide a better life for its communities. On the other hand, district of Northeast Kei Besar is classified as an incapable area to food self-sufficient because the existing population is greater than the availability of rice to food self-sufficiently, namely 2000 people. This shows that there is no balance between the population, demand and the availability of rice in district of Northeast Kei Besar during the year. This means that this area is threatened with food insecurity. By considering the population in this district which is still high above the optimal food self-sufficiently, the following policies are recommended: (1) expansion of upland rice farming on suitable land, (2) migration of population to other less-populated districts; (3) sharing of rice food products from surplus areas to deficit areas and or (4) equitable development to divide population concentrations in these areas.

Abstract

Research has been conducted with the aim of mapping a potential landslide of soil that is alleged to be happening on a national road development area on the island of North Maluku Sanana island because in some locations excavations or cutting slope were conducted for build trails. Research was done by survey method, by analysis of land as well as the analysis of soil samples in the laboratory against some physical-chemical soil parameters to predict the potential for landslide of soil. The results showed that in the developed area of national roads, there were some points or locations with the potential landslide. However, by cutting slope of landslide the potential became greater, things which would be very threatening road users on the sections of the road that passes through the hilly and mountainous regions. The cutting slopes have been disturbing the equilibrium slope stability or lower slopes so the landslide is easy to happen. Mitigation efforts can be done by building a retaining structure at the foot of the slopes, the angle of the cutting slope made slightly sloping and in the upper part land use should be preserved and enriched with plant conservation to improve the stability of slopes. Keywords: a potential avalanche of soil, national road, slope stability ABSTRAK Penelitian telah dilakukan dengan tujuan untuk memetakan potensi longsoran tanah yang diduga akan terjadi pada kawasan pengembangan jalan nasional di Pulau Sanana Maluku Utara karena di beberapa lokasi dilakukan penggalian atau pemotongan lereng untuk membangun jalur jalan. Penelitian dilakukan dengan metode survey dengan analisis lahan serta analisis sampel tanah di laboratorium terhadap beberapa parameter fisik-kimia tanah untuk memprediksi potensi longsoran tanah. Hasil penelitian menunjukkan bahwa pada kawasan ruas jalan nasional yang dikembangkan terdapat beberapa titik atau lokasi dengan potensi longsoran tergolong sedang. Namun dengan adanya pemotongan lereng maka potensi longsoran menjadi semakin besar, hal mana akan sangat mengancam pengguna jalan di ruas-ruas jalan yang melewati kawasan berbukit dan bergunung. Pemotongan lereng telah mengganggu keseimbangan lereng atau menurunkan stabilitas lereng sehingga longsoran mudah terjadi. Upaya mitigasi dapat dilakukan dengan membangun struktur penahan di kaki lereng, sudut pemotongan lereng dibuat landai dan penggunaan lahan di bagian atas lereng harus dipertahankan dan diperkayadengan tanaman konservasi untuk meningkatkan stabilitas lereng yang sudah terganggu. Kata kunci: jalan nasional, potensi longsoran tanah, stabilitas lereng

Abstract

The aims of this research are to find the dominant pollutants in estuarine of Way Tomu and Way Lela, determine the water quality in the estuary Way Tomu and Way Lela, and comparing the effects of the density of settlement on water quality of estuary Way Tomu and Way Lela. The research was conducted in October until November 2015. The method used was survey method with variables the physical parameters (Total Dissolved Solid, Total Suspended Solid, temperature), chemicals parameter (detergents, nitrate, nitrite, pH, BOD, COD, DO, amonia, phosphate, iron, oil and fat, manganese, coopper) and biology parameter (E. coli) class II. The result showed that the dominant chemicals parameter and affect water quality in the Way Tomu is Detergent (746 mg/L), while for the Way Lela estuary are detergent (835 mg/L), phosphate (0,4631 mg/L), and dissolved oxygen (3,2 mg/L), and biological parameters i.e., E. coli. These values have exceeded the value of the quality standard of the water quality is appropriate Government Regulation Number 82 the Year 2001 about Water Quality Management and Control of Water Pollution Classes II. It is thought to be due to the behavior of the people who live the area of the riverbanks of Way Lela and Way Tomu that their household trash into the river. For that is a need for the attention of the Government and local communities to improve the quality of the river water in the Way Tomu and Way Lela with improving the environment-friendly behavior. Keywords: pollutants, pollution estuary, way Tomu, way Lela ABSTRAK Tujuan dari penelitian ini adalah untuk menemukan polutan yang dominan di muara Way Tomu dan Way Lela; menentukan kualitas air di muara Way Tomu dan Way Lela; serta membandingkan efek dari kepadatan pemukiman terhadap kualitas air muara Way Tomu dan Way Lela. Penelitian ini telah dilakukan pada bulan Oktober sampai November 2015. Metode yang digunakan adalah metode survei dengan variabel penelitian berupa parameter fisik (Total Dissolved Solid, Total Suspended Solid, suhu), parameter kimia (deterjen, nitrat, nitrit, pH, BOD, COD, DO, amonia, fosfat, besi, minyak, dan lemak, mangan, tembaga) dan parameter biologi (E. coli) kelas II. Hasil penelitian menunjukan bahwa parameter kimia yang dominan dan mempengaruhi kualitas air di muara Way Tomu adalah Deterjen (746 mg/L) sedangkan untuk muara Way Lela adalah Deterjen (835 mg/L), Fosfat (0,4631 mg/L), dan Oksigen terlarut (3,2 mg/L), serta parameter biologi yaitu E. coli. Nilai-nilai ini telah melampaui nilai baku mutu kualitas air Sesuai Peraturan Pemerintah Nomor 82 Tahun 2001 tentang Pengelolaan Kualitas Air dan Pengendalian Pencemaran Air Kelas II. Hal ini diduga sebagai akibat perilaku masyarakat yang tinggal di daerah bantaran Way Tomu dan Way Lela yang membuang limbah rumah tangga ke sungai. Untuk itu perlu adanya perhatian pemerintah dan masyarakat setempat untuk memperbaiki kualitas air sungai di Way Tomu dan Way Lela dengan meningkatkan perilaku ramah lingkungan. Kata Kunci: bahan pencemar, pencemaran muara sungai, way Tomu, way Lela

Abstract

Cucumber is consumed regularly by inhabitants of Buru District of the Maluku Province, and, its productivity needs to be optimized. Soil tillage and plant density in cucumber cultivation have Influences on competition for nutrient intake, water and light and hence affect plant yield. The aim of this field experiment was to study growth and yield responses of cucumber (Cucumis sativus L.) on different soil tillage systems and planting densities. The field experiment was arranged in a factorial Randomized Block Design to examine several tillage methods (one and two) and planting densities (25 x 25 cm, 40 x 40 cm and 45 x 55 cm). The experimental results showed that there was no effect of interaction between soil tillage and planting density on all variable observed. Single and double tillage methods increased fruit number, fruit diameter, fruit length, fruit weight and root length of cucumber, while planting density gave no effect on all variables measured. Therefore, either single or double tillages and any planting densities tested in this experiment could be recommended in cucumber cultivation in Buru District of Maluku Province.

Abstract

This study aims to determine the carrying capacity of agricultural land and settlements in Tial Village, Salahutu Subdistrict, as a control over the agricultural sector and settlement development. This research used a survey method of field activities, including observing and measuring the land's carrying capacity in the field. The study results indicated that Tial Village has a high carrying capacity for settlements due to the land area suitable for settlement and the number of residents in each landform. On the other hand, the carrying capacity of agricultural land is low, so the food supply in Tial Village is classified as low to very low. This fact indicates that there is a dominant influence on residential land cover. It is concluded that every known specific land use suitability can be utilized optimally and sustainably.
