Judul: Re-Design of mahakam irrawaddy dolphin (Orcaella Brevirostris Gray, 1866) conservation based on distributional changes in Mahakam River, East Kalimantan
Abstrak: The intensive bio-ecological research on the Mahakam dolphins (Orcaella brevirostris Gray,1866) from 1997 to 2004 revealed that there were two core habitats/core areas with high dolphin densities in the Mahakam River i.e. the MuaraPahu-Penyinggahan area and Pela-Muara Kaman area. Since 2007, there have been unusual occurrences within the distribution of the Mahakam dolphins. The core habitat of Muara Pahu-Penyinggahan, which was previously known to support a large population of Mahakam dolphins has apparently been left. The changes in distribution were also detected in 2010 when the population monitoring was conducted and no individuals were found in the Muara Pahu-Penyinggahan core habitat . The Mahakam dolphins are now more concentrated in the area of Muara Muntai and in their other core habitat, Pela-Muara Kaman. This research aimed to reveal whether the changes in distribution were persistent and to respond to this phenomenon by improving the conservation design. To predict the persistency of these changes population dynamics, habitat and socio-political environmentv(policies) were studied and formed the research goal.. Thus, the research objectives of this dissertation are as follows: 1) predicting the survival of the Mahakam dolphin population for a period of100 years, 2) analyzing the characteristics of the Mahakam dolphin habitats; 3) evaluating the effectiveness of coordination and consistency of the Mahakam dolphin conservation policies; and 4) perfecting the design of dolphin conservation to accommodate the current situation of the population, the Mahakam dolphin habitat and socio-political environment that support the conservation efforts. The research on the population of Mahakam dolphins in 2012 revealed that the individual number of Mahakam dolphins, the number of births, and the number deaths were as many as 92 individuals, 5 individuals, and6 individuals, respectively. This research also demonstrated that changes in the distribution of dolphins had occurred inMahakam River. The Mahakam dolphins do no longer live in their core habitat of PenyinggahanMuaraPahu. Currently, the dolphin habitat is concentrated in the core habitat of Pela-Muara Kaman. The changes in the distribution indicate that further shrinkage in the habitat of Mahakam dolphins has occurred Mahakam River. As a result of this, an analysis on the survival of the Mahakam dolphin population was conducted. The results of the analysis predict that the life chances of the Mahakam dolphin population in the next one hundred years are less encouraging as the number of individuals will continue to diminish. The only scenario that predicts a stable dolphin population in one hundred years is when the mortality rate of dolphins is reduced to two individuals per year with the conditions that there is no further shrinkage of habitat, which will result in the reduction of its carrying capacity, and the birth rate is maintained at five individuals per year. vii Networks for coordination for dolphin conservation, which includes 16 organizations have not been effective. There has been a lack of coordination in most networks especially related to organizations/actors included in groups (factions) that work in WestKutai Regency. The lack of coordination started from the time when the dolphins moved away from their conservation area and habitat in Muara Pahu. There has been no coordination

Abstrak: Irrawaddy dolphin (Orcaella brevistoris) is a protected spesies area and in Appendix I of CITES 2009. Objectives of this study were to analyze the relationship between perception and attitudes of the community with the habitat conditions of the irrawaddy dolphin in Semayang Lake and Melintang Lake for irrawaddy dolphin sustainability and also formulating efforts to conserve irrawady dolphin. This study was conducted in Semayang Lake, Melintang Lake, and its surrounding on July to August 2009. Tools and materials used in this study were a questionnaire, bottled water samples, the rope with weights, secchi disc, litmus paper, watches, net and motorboat. Data in this study consisted from two main types data, which were irrawady dolphins’s habitat characteristic and data of community perceptions and attitudes about irrawaddy dolphins. Enclosed questionnaires and interviews methods used to obtain data of perception and attitudes. likert scale used to analyze data of community perception. Descriptive analysis used to analyze community attitude data. Community perceptions of irrawady dolphins were positive, based on likert scale analysis. Government rules very affected in conservation action to irrawady dolphin;s conservation action and have highest value compared to another variables and the score was 523 with the average was 4, 36, and it’s mean that the community realized that government was very important to irrawaddy dolphin’s sustainability. Based on interview result to the community, there were some attitude which have negative impact to irrawaddy dolphin’s habitat which were throwing the garbage to the water. The depth of Semayang Lake was (1,15-2 m) and Melintang Lake was (0,75-1,5 m) and impossible for irrawady dolphin to live there due to their large body size. Fish productivity in both lake is very low, which were 1,8 kg/net/day in Semayang Lake and 2,25 kg/net/day for Melintang Lake. Water traffic frequency in mouth area of Pela River in holiday is higher (55 times/hour) than in working day (54 times/hour). Lack productivity of fish and water traffic caused Irrawady dolphins could not be found in both lake because irrawady dolphins preferred area which have a lot of fish and calm stream water. Based on problem above, there some action can be done for irrawaddy dolphins sustainability which are managing habitat, setting the habitat as a conservation area, dredging the lake, make alternative way in water traffic, law enforcement, and make law about fishing procedures. Delivering information to the community about environment health education can be done to change community attitude that related to irrawady dolphins sustainability. Knowledges about environment health is very important to raise people awareness about the importance of Irrawaddy dolphins.

Judul: Kajian Pembuatan Tepung Cake Tape Ubi Kayu (Munihot Escu/E/1tu Crantz) Instan Dan Penerlmaan Konsumen Terhadap Mutu Organoleptik Cake
Abstrak: Pada umumnya bahan pangan dikonsumsi dalam bentuk tidak seperti bahan mentahnya, tetapi diolah menjadi berbagai bentuk aneka produk pangan. Selain untuk menambah ragam pangan, pengolahan juga bertujuan untuk memperpanjang masa simpan bahan pangan tersebut. Penggunaan tape ubi kayu sebagai bahan dasar pembuatan cake sudah banyak dilakukan di rumah tangga. Akan tetapi karena keterbatasan teknologi, tape seringkali sulit digunakan untuk bahan tambahan cake. Produk-produk instan (cake mix) saat ini banyak disukai di masyarakat. Kemajuan teknologi menuntut kepraktisan dalam segala hal. Tujuan penelitian pembuatan tepung cake tape instan ini, selain untuk kepraktisan diharapkan juga dapat memperluas distribusi dan pemakaian dari tape serta memperpanjang umur simpan tape. Pada penelitian ini tape dibuat dengan menggunakan ragi MK dengan konsentrasi 0,1% dari berat awal. Pembuatan tepung cake instan dibuat dengan 2 metode yaitu dengan memisahkan telur dan margarin sebelum dikeringkan dan mencampurkan telur dan margarin pada saat adonan dikeringkan dengan drum drier. Pada penelitian ini metode yang diambil adalah dengan memisahkan telur dan margarin sebelum dilakukan pengeringan. Formulasi yang dibuat adalah dengan membandingkan terigu dan tape. Adonan dibuat dengan perbandingan terigu dan tape sebesar 1: 1, 1 :2, 1 :3, 1:4 dan mengikuti resep standar. Dari uji organoleptik terhadap tepung instan dan cake, secara umum panelis menyukai formulasi 1: 1 dibandingkan formulasi lainnya. Berdasarkan uji tingkat kesukaan, formulasi 1: 1 memiliki nilai yang lebih tinggi, untuk itu dalam analisa selanjutnya formulasi 1: 1 dibandingkan cake kontrol dan formulasi 1:4 yang memiliki tingkat kesukaan terendah. Analisa dilakukan terhadap sifat fisik dan kimia yang didasarkan hasil uji organoleptik. Analisa yang dilakukan diharapkan dapat menunjang keakuratan panelis. Analisa secara statistik dilakukan dengan analisis sidik ragam (ANOVA) dan dilanjutkan dengan uji lanjut Duncan. Analisa dilakukan terhadap tepung instan dan cake. Analisa kadar air tepung instan berbeda nyata untuk ketiga cake tersebut. Nilai kadar air tepung instan yang dihasilkan berkisar antara 2,396 - 3,553 %. Kadar air tertinggi yaitu formulasi 1 :4. Hal ini disebabkan penambahan tape yang lebih banyak, dapat meningkatkan kadar air tepung. Rendemen pada berbagai ukuran (60, 80, 100 mesh), nilai tertinggi adalah tepung instan kontrol (tidak ditambahkan tape). Nilai rendemen 60 mesh untuk tepung instan kontrol, formulasi 1 :1, formulasi 1:4 berturut-turuuidalah 66,588 %, 66,018%, dan 63,286 %. Rendemen 80 mesh berturut-turut adalah 43.909 %, 35.125 %, dan 34.896 %. Rendemen 100 mesh memiliki nilai berturut-turut adalah 34.1641 %, 24.288 %, dan 23.528 %. Untuk tepung instan formulasi 1:1 memiliki rendemen yang lebih tinggi. Untuk pemasaran, tepung dengan rendemen 60 mesh lebih ekonomis jika dipasarkan karena rendemennya lebih dari 50%. Penyerapan air pada tepung yang penambahan tape lebih banyak, akan lebih besar dibandingkan tepung lainnya. Penyerapan air formulasi 1:4 nilainya 1.639, untuk cake kontrol 0.402, dan untuk formulasi I: I nilainya 1.579. Derajat putih sebagai parameter untuk warna pada tepung instan yang mengandung tape lebih rendah, karena tape yang mengandung gula mengalami reaksi browning akibat kontak dengan panas. Derajat putih formulasi 1:4 yaitu 53,4 %, sedangkan untuk tepung instan kontrol dan forrnulasi I: I berturut-turut adalah 70.4 % dan 56.75 %. Kadar gula formulasi 1:4 lebih tinggi yang berasal dari penambahan tape yang lebih banyak. Kadar gula dari
