Abstract

Abstract Go green campaign is one of ways to save the earth from garbage. Thiscampaign not only suggestsrecycling and reducing but also reusing the garbage. In line with the go green campaign, the aim of this study is to achieve the viability of using Bagasse Ash (BA) as additive material in hot mix Split Mastic Asphalt (SMA) with certain comparison which is expected to improve the quality of SMA. This research was conducted by using experiment research design in comparison among the three types of (without BA and with BA)properties of the hot SMA toward the Marshall properties (stability, flow, Marshall Quotient (MQ), Void In Total Mix (VITM), Void Filled Without Asphalt (VFWA),and Air Void to get Optimum Bitumen Content ,Indirect Tensile Strength (ITS) at different temperature (20oC,40oC,60oC) and Unconfined compressive at same temperature room at 27oC but different percentage of BA (3%,4% ,5%). The results of this research are as follows: 1) the properties of the hot mix SMA toward the Marshall properties are: The stability value of SMA with BA is higher than SMA withoutBA by 3%; The flow value of SMA with BA is lower than SMA without BA by 5.5%; The Marshall Quotient value of SMA with BA is higher than SMA without BA by 5%; TheAir void value of SMA withBA is lower than SMA without BA by 3%; The VFWA value of SMA with Bagasse Ash is higher than SMA without BA by 75.87%; The Air Void value of SMA with BA is lower than SMA without BA by 2%.In terms of ITS value, the value of ITS is high when BA is combined with low temperature; but when the temperature is increased, the value of ITS decreases. Moreover, in terms of UCS, the value of UCS of BA mixture is higher than SMA and higher than normal mixture at normal temperature. The recommendation of this research is that a certain percentage of air voids is necessary in all dense-graded mixes to prevent the pavement from flushing, shoving, and rutting. Air voids may be increased or decreased by lowering or raising the binder content. They may also be increased or decreased by controlling the amount of material passing the No. 200 sieve in the HMA. The more fines added to the HMA generally the lower the air voids. The air voids may be changed by varying the aggregate gradation in the HMA. Keywords: Bagasse Ash, Split Mastic Asphalt, ITS, UCS

Abstract

Millenium Development Goals (MDGs) Indonesia menetapkan “Penanggulangan Kemiskinan dan Kelaparan” sebagai target pencapaian yang pertama. Kendala utama adalah kurangnya kemampuan untuk keluar dari garis kemiskinan karena biasanya kelembagaan masyarakat di lingkungan tersebut kurang memberi akses bagi penyertaan sosial, pemberdayaan, maupun keamanan. Penelitian ini bertujuan, pertama untuk mencari Konsep Model Pemberdayaan Masyarakat Permukiman Kumuh Sebagai Upaya Pengentasan Kemiskinan Perkotaan Yang Berkelanjutan (PMPKB) dan kedua, untuk menerapkan konsep Model PMPKB. Metode yang digunakan adalah Participatory Action Research (PAR) yang menempatkan peneliti dan yang diteliti dalam satu kerangka proses. Model PMPKB diterapkan di 5 kelurahan di kota Surakarta. Hasil di kelurahan Joyosuran menunjukkan bahwa Model PMPKB yang dimulai dari pemetaan masalah partisipatif sampai dengan rencana tindak komunitas serta diakhiri dengan pengintegrasian dengan rolling plan perencanaan pada tingkat kota, bisa menjadi instrumen untuk mengakomodasi aspirasi masyarakat melalui perencanaan dari bawah (bottom-up planning) yang bisa menjamin dan memastikan terintegrasinya proses bottom-up planning pada level kelurahan (sub kota) di dalam dokumen perencanan pada level kotaKata Kunci: Perencanaan Partisipatif; Kelurahan; Kemiskinan; Pemukiman Kumuh; Perkotaan; Model ; Pemberdayaan Masyarakat The Indonesia’s Millenium Development Goals (MDGs) has designated “the Eradication of Poverty and Hunger” as the first target of achievement. The main obstacle is the lack of capability to escape from the poverty line because community institutions in the neighborhood do not sufficiently provide access for social inclusion, empowerment, and security. This research aims at, first, finding the Model of Slums Settlement Community Empowerment Concept as an effort for Sustainable Urban Poverty Alleviation (PMPKB), and second, implementing the PMPKB concept model. The method used in this research is Participatory Action Research (PAR) where the researchers and the object of research are put in one process framework. This model was implemented in 5 districts in Surakarta municipality. The implementation of the model at Joyosuran district shows that the PMPKB model which begins with the mapping of participative problems until community action plan and ends with the integration with the rolling plan at the municipality level, can become an instrument to accommodate community aspiration through bottom-up planning that can guarantee and ensure the integration of bottom-up planning at the district level in the planning document at the city level.Keywords: Participative planning, District, Poverty, Slums Settlement, Urban, Model, Community Empowerment

Abstract

Citra kota merupakan gambaran mental dari sebuah kota sesuai dengan rata-rata pandangan masyarakatnya. Pemahaman seseorang tentang suatu kota akan lebih mendalam daripada sekedar kesan visual. Pemahaman tentang legibility ini selalu berkaitan dengan 3 komponen didalamnya yaitu identitas, struktur, dan makna. Identitas merupakan objek-objek atau elemen yang berada pada suatu kota yang dapat membedakan dengan kota lainnya. Struktur yaitu pola hubungan yang saling berkaitan dengan elemen-elemen pembentuk citra kota yang dapat dipahami oleh pengamat. Makna merupakan pemahaman dalam kedua komponen (identitas dan struktur) berdasarkan dengan budaya, politik, kultur, sejarah, symbol, maupun keunikan. Kota Solo atau Kota Surakarta merupakan kota yang terkenal akan budaya dan kearifan lokalnya. Hal ini berkaitan erat dengan keberadaan dua keraton besar yang berada pada kota ini yaitu Keraton Kasunanan dan Keraton Mangkunegaran. Oleh sebab itu, peneliti mengungkapkan seberapa kuat Citra Kawasan terjadi pada kawasan-kawasan budaya terutama pada Kawasan Pura Mangkunegaran yang memiliki nilai historikal dan kebudayaan yang cukup kental, namun seiring dengan berjalannya waktu banyak pertumbuh perdagangan jasa yang mengitari Kawasan Pura Mangkunegaran. Hal ini dapat mempengaruhi Citra Kawasan pada kawasan Pura Mangkunegaran, bahkan pada gambaran/image masyarakat terhadap kawasan Pura Mangkunegaran ini akan berbeda. Tujuan dari penelitian ini adalah untuk menganalisis elemen Citra Kawasan Mangkunegaran berdasarkan penilaian Stakeholder dengan konsep legibility. Metode yang digunakan dalam penelitian ini adalah teknik analisis deskriptif dengan menggunakan teknik analisis deskriptif untuk analisis elemen pembentuk Citra Kawasan Mangkunegaran berdasarkan penilaian Stakeholder. Hasil penelitian ini menunjukkan bahwa Citra Kawasan Mangkunegaran dengan konsep legibility ini untuk mengetahui komponen identitas dan struktur kawasan. Dari hasil penelitian diketahui bahwa identitas Kawasan Mangkunegaran berdasarkan Stakeholder adalah Gapura Mangkunegaran (landmark), Jalan Ronggowarsito (path kendaraan), Jalan diponegoro (path pedestrian), Pura Mangkunegaran (district), Tembok Mangkunegaran (edges), Masjid Al-Wustho (nodes). Sedangkan untuk struktur dapat dilihat dari keterkaitan hubungan antara elemen-elemen pembentuk Citra Kawasan Mangkunegaran. Keterkaitan antara landmark dengan district ini merupakan salah satu penghubung antara pintu masuk dengan Pura mangkunegaran itu sendiri yang mana Gapura sebagai landmark dan Pura Mangkunegaran sebagai districtnya.

Abstract

Jalan Margonda Raya merupakan jalan arteri yang sekaligus berfungsi sebagai jalan utama di Kota Depok, Jawa Barat. Koridor jalan tersebut merupakan salah satu kawasan yang mengalami perkembangan pemanfaatan lahan akibat adanya Universitas Indonesia (UI). Perkembangan pemanfaatan lahan di kawasan tersebut berorientasi memenuhi kebutuhan mahasiswa sehingga mengakibatkan fungsi pemanfaatan lahan di sepanjang koridor Jalan Margonda Raya menjadi beragam. Pemanfaatan lahan yang beragam membangkitkan pergerakan penduduk dari satu tempat ke tempat lainnya dalam upaya pemenuhan kebutuhan yang juga mempengaruhi volume pergerakan di koridor tersebut. Berdasarkan fenomena tersebut, penelitian ini dilakukan dengan tujuan untuk mengetahui hubungan pemanfaatan lahan dengan volume pergerakan di Jalan Margonda Raya, Kota Depok. Data yang dikumpulkan dalam penelitian ini berdasarkan observasi lapangan dan traffic counting pada 32 titik. Data tersebut selanjutnya di analisis mengunakan teknik pemetaan dan statistik deskriptif untuk mengetahui jenis dan luasan pemanfaatan lahan, volume lalu lintas untuk mengetahui volume pergerakan, serta korelasi dan deskripsi untuk mengetahui hubungan dan karakteristik. Hasil penelitian menunjukan bahwa terdapat hubungan yang kuat antara pemanfaatan lahan dengan volume pergerakan yang terjadi pada koridor Jalan Margonda Raya. Hubungan kuat tersebut menunjukkan karakteristik bahwa semakin luas pemanfaatan lahan pada kawasan penelitian, aktivitas yang terjadi pada pemanfaatan lahan tersebut semakin beragam sehingga menyebabkan tingginya volume pergerakan.
