Abstract

Penelitian ini difokuskan pada pemodelan Jaringan Syaraf Tiruan untuk prediksi Panjang Musim Hujan, dengan mengambil studi kasus stasiun Sumur Watu di Indramayu. Peubah yang dipergunakan sebagai prediktor adalah Suhu Permukaan Laut pada bulan Juni, Juli dan Agustus yang berupa data grid dan dipilih berdasar nilai korelasi pada taraf nyata 5% dan 10%. Sedangkan peubah respon adalah panjang musim hujan satu periode ke depan yang diukur dalam dasarian (10 harian). Dari 17 tahun periode data, selanjutnya dilakukan pemodelan JST dengan 4 variasi jumlah hidden neuron (5, 10, 20 dan 40) dan 3 laju pembejaran (0.3, 0.1 dan 0.001) pada 6 data set kombinasi dari 3 jenis bulan dan 2 jenis taraf nyata, dan dilakukan dengan 4-fold cross validation untuk melihat skil dari model dalam melakukan prediksi . Selain itu juga dilakukan pemodelan jaringan syaraf tiruan dengan menggunakan grid yang secara konsisten nyata berpengaruh pada panjang musim hujan baik untuk suhu muka laut pada bulan Juni, Juli, ataupun Agustus. Hasil percobaan menunjukkan bhawa suhu muka laut pada bulan agustus memberikan skil tertinggi dengan akurasi 81% dan 84%. Sedangkan untuk bulan Juni dan Juli berkisar sekitar 50%. Prediksi dengan SST pada grid yang konsisten memberikan akurasi sebesar 65%.

Abstract

The style of the party facing a conflict (conflict style) needs tobe known to  find an effective dispute resolution. The main actors and supporting actors and interests/role and influence or power and its relationship needs to be carefully mapped. What are the actions that can be taken to resolve the conflict based on the style of the parties is something that needs to be answered in this study. In this study conflict styles of actors assessed  using conflicts style analysis (AGATA). This study shows that the conflict-style compromise, accommodation and collaboration facilitated and mediated for proposing Village Forest, Community Forest Partnership  to obtain legal recognition on managing state forest land as well as recognizing state forest, hence the issuance of permits The Village Forest and Community Forest Partnership can be  accelerated. The role of outside parties who are not related with conflict is essential to facilitate and mediate the parties to a conflict resolution. Competing parties need  to be  mediated so his style could change to compromise, accommodation or collaboration. Even if his style would remains unchanged it  will result in a constructive option to acquire rights to the land through forest discharge process. To the avoiding-style party an  intensive communication needs to be done  in order to be aware of the conflict or change his style to compromise.

Abstract

ABSTRACTClimat change (CC) which contributed to increased conflict/war had implicitly emerged in the IPCC’s 3rd and 4th reports (IPCC, 2001; 2007); meanwhile on the 5th report (IPCC, 2014) emphasized more on human security. The risk/impact of CC to human security was shown through interaction between livelihood, conflict, culture, and migration. The purpose of the stydy was to gained an understanding of the correlation between CC and the occurrence of conflict/war; knowing the  impacts of CC on national resilience; explaining the phenomenon of CC on national resilience; and explained the linkages between human security and national resilience.This research was done through conceptual and comparative approach.The results showed that CC did not contribute directly to the occurrence of conflict/war;the impact of CC disrupts people's livelihoods thereby reducing national resilience; CC could be viewed as a disturbance and/or threat; and basically national resilience and human security could be synchronized because both of them seeked to brought guarantee for the security, safety, and individual prosperity.ABSTRAK Perubahan iklim (PI) diasumsikan berkontribusi terhadap meningkatnya konflik/perang. Pandangan tersebut secara implisit telah muncul dalam laporan Panel Antarpemerintah tentang Perubahan Iklim(IPCC)ke-3 (IPCC TAR, 2001) dan ke-4 (IPCC AR4, 2007); sebaliknya pada laporan ke-5 (IPCC AR5, 2014) memfokuskan pada keamanan manusia. Skema risiko PI pada keamanan manusia ditunjukkan melalui interaksi antara mata pencaharian, konflik, budaya, dan migrasi. Penelitian ini untuk menjelaskan korelasi antara PI dengan terjadinya konflik/perang; menggambarkan dampak PI bagi ketahanan nasional (Tannas); menjelaskan isu PI ditinjau dari konsepTannas; dan menjelaskan keterkaitan antara  keamanan manusia dengan Tannas. Penelitian dilakukan melalui dua pendekatan, yaitu: pendekatan konseptual dan pendekatan komparatif.  Diperoleh hasil bahwa PI tidak berkorelasi langsung terhadap terjadinya konflik/perang; PI mengganggu mata pencaharian masyarakat, sehingga menurunkan Tannas; dalam konsep Tannas, PI merupakan gangguan dan atau ancaman; dan Tannas dapat disetarakan dengan keamanan manusia karena keduanya berupaya menghadirkan penjaminan keamanan, keselamatan, dan kesejahteraan individu.

Abstract

Land and forest fire is one of causes ofland degradation in Central Kalimantan. Remote sensing dataapplications, especially READY-ARL NOAA and CMORPH data, are benefit forthe available climate observation data. The objectives of this research are: (1) to analyzis relationship between hotspots, FDRS and occurences of land and forest fire, and (2) to develop the estimation model of burned area from hotspot and FDRS codes. The result of this research showed that burned area can not be estimated by using number of hotspots. The drought code (DC) wich is one of FDRS codes has correlation with burned area. So, burned area can be estimated using drought code (DC) (R-sq = 58%) by using the following formula: Burned Area (Ha) = -62.9 + 5.14 (DC – 500).Keywords: land and forest fire, NOAA, CMORPH, hotspot

Abstract

Central Kalimantan Province is a region with high level of forest/land fire, especially during dry season. Forest/land fire is a dangerous ecosystem destroyer factor, so it needs to be anticipated and prevented as early as possible. CMORPH rainfall data have good potential to overcome the limitations of rainfall data observation. This research is aimed to obtain relationship model between burned acreage and several variables of rainfall condition, as well as to develop risk prediction model of fire occurrence and burned acreage by using rainfall data. This research utilizes information on burned acreage (Ha) and CMORPH rainfall data. The method applied in this research is statistical analysis (finding correlation and regression of two phases), while risk prediction model is generated from the resulting empirical model from relationship of rainfall variables using Monte Carlo simulation based on stochastic spreadsheet. The result of this study shows that precipitation accumulation for two months prior to fire occurrence (CH2Bl) has correlation with burned acreage, and can be estimated by using following formula (if rainfall ≤ 93 mm): Burnt Acreage (Ha) = 5.13 – 21.7 (CH2bl – 93) (R2 = 67.2%). Forest fire forecasts can be determined by using a precipitation accumulation for two months prior to fire occurrence and Monte Carlo simulation. Efforts to anticipate and address fire risk should be carried out as early as possible, i.e. two months in advance if the probability of fire risk had exceeded the value of 40%.

Abstract

The events of climate extreme that increase the crop yield uncertainty causing financial loss of farmers. To ensure economic profitability, farmers need to tailor their cropping pattern to the climate forecast. The study was conducted in Ciparay and Bojongsoang sub-District, the central crop production of Bandung District from March to August 2005. Research aimed to analyze climate information value based on farming system strategy for accruing farmer income. Farming system in climate extremeevents was determined by maximizing expected utility of wealth. Farming system in two sub-District was assessed by Rapid Rural Appraisal. Climate information value was the difference between income with conventional farming and income using farming system strategy. Result of the survey indicated that dominant cropping pattern in the study area was rice-rice-fallow. The second rice was vulnerable to drought particularly in extremeyears. Further analysis suggested that extreme climate events were mostly associated with ENSO (El-Niño Southern Oscillation) events. From farming system simulation model, it was found that in El-Niño years, to maximize income, farmers should planted all farm with maize. Planting non-rice crops can be done after April (early May), to get maximist income, they should plant all farm with soybean. Risk averter farmers might diversify their crops, i.e. by fallowing part of their lands and planting the remaining lands with maize and soybean. The use of climate information in El-Niño years will give higher economic benefit to farmers than in La-Niña years. The difference in economic benefit was determined by the proportion of land allocated for rice and nonrice crops. In El-Niño years, farmers who plant all their lands for second planting with rice crop will get loss due to significant decrease in rice yield, while those who plant part or all of their land with non-rice crops will gain benefit as they will get yield. Therefore, farmers who are willing to take risks by planting part or all of their land with non-rice crops in years which were forecasted to be El-Niño years will get higher income than farmers who are not willing to change their rice crops.
