A study was conducted to investigate the effect of cassava meal fermented to productivity of broiler chickens. This study used a completely randomized design (CRD) with 4 treatments and 5 replications, each redication was filled with 3 chicks so that the number of chicks in this study was 60 chicks. The variables observed were initial weight, ration consumption, body weight gain, feed conversion, final body weight, morbidity and mortality. The treatments were P0 (research ration with 5% cassava meal), P1 (research ration with 3% cassava meal fermented), P2 (research ration with 6% cassava meal fermented), P3 (research ration with 9% cassava meal fermented). The results showed a significant difference from these facts, but not significantly different on body weight gain, ration conversion and final body weight. The average initial weight was 45.55 grams/birds, the morbidity rate were 2 chicks the mortality rate was also 0.17%. Giving cassava meal fermented up to 9% can be consumed by broiler chickens without reducing productivity.A study was conducted to investigate the effect of cassava meal fermented to productivity of broiler chickens.

MARKOVNIKOV ADDITION OF CHLOROSULFURIC ACID TO EUGENOL ISOLATED FROM CLOVE OIL

The objective of this research was to synthesize new compounds with potential biological activity from readily accessed natural products. Eugenol has been reported to posses antioxidant and anticancer properties and was prepared by extracting from clove buds with dichloromethane and followed by isolation using column chromatography to afford pure eugenol (73%). In an attempt to enhance intrinsic activity of this natural compound, some derivatives were possible to synthesize. The main aim of this preliminary research was to transform eugenol to become sulfonic derivative. Eugenol was transformed to its sulfonic derivative in moderate yield (64%) by treatment with chlorosulfuric acid which undergoes Markovnikov addition. This product was rapidly confirmed by GC-MS and NMR analyses. Selective inhibition was performed by cyclic sulfonic ester derivative which could inhibit Eschericia coli and Staphylococcus aureus but not for Bacillus cereus

KAJIAN RUANG PUBLIK KOTA ANTARA AKTIVITAS DAN KETERBATASAN

Ruang esensinya adalah tempat manusia hidup dan beraktivitas. Namun tidak semua aktivitas dapat terakomodir karena setiap ruang dibatasi dengan fungsinya masing-masing. Bagi ruang pribadi keterbatasan ruang tersebut merupakan karakteristik utama bagi ruang itu sendiri sedangkan pada ruang publik yang memiliki berbagai macam aktivitas harus dapat menampung berbagai aktivitas di dalamnya. Untuk itulah perlu dilakukan kajian mengenai ruang publik terhadap permasalahan keterbatasan ruang yang sering ditemui. Tulisan ini menggunakan metode kualitatif dengan melakukan pendekatan kajian literatur. Ada beberapa literatur yang diambil dari beberapa ahli serta beberapa hasil penelitian dalam artikel jurnal untuk mendukung teori dan melihat kenyataan di lapangan. Pada akhir tulisan diambil suatu kesimpulan bahwa keterbatasan ruang publik terhadap berbagai macam aktivitas yang berlangsung di dalamnya dengan terbentuknya ruang bersama baik secara permanen maupun bergantian (waktu tertentu). Kata-kata Kunci: arsitektur, ruang publik, aktivitas, ruang bersama URBAN PUBLIC SPACE STUDIES BETWEEN ACTIVITIES AND LIMITATIONS The essence of space is a place where humans live and doing their activities. But not all activities can be accommodated because space is limited by their functions. For private space, space limitations are the main characteristics for space itself, while in public spaces that have various kinds of activities must be able to accommodate multiple activities in it. For this reason, a study of public space needs to be done on the problems of space limitations that are often encountered. This paper uses qualitative methods by conducting a literature review approach. There is some literature taken from several experts and several research results in the journal for support the theory and see the reality in the field. At the end of the writing, it was concluded that the limitations of the public space for various kinds of activities take place in it with the formation of shared spaces both permanently and alternately (certain times).

ブアメラ (Pandanus conoideus) ザンサ ヲ キュウヨ シタ ブロイラー ノ セイチョウ トタイセイジョウ オヨビ ニクシツ ニ ツイテ

本試験はブロイラー雛へのブアメラ残さ(RFW)給与がブロイラーの成長,と体性状および肉質に及ぼす影響について検討することを目的とした。ブアメラはタコノキ科の樹木で約10kgになる果実を年2回収穫できる。果肉は脂質とカロテノイドに富み,インドネシアでは蒸すか,煮て食している。本試験は5試験区,4群の完全無作為法で実施した。200羽の雌雄無鑑別ロス系ブロイラーの初生雛を1ケージ(1m×1m×1m)に10羽ずつの20ケージに配分した。対照区(T_0)には粗タンパク質19%,代謝エネルギー3200kcal/kgの基礎飼料を給与し,試験区1～4には基礎飼料にRFWを0.5,1.0,1.5,2.0%添加した飼料を35日間給与した。体重と飼料摂取量は毎週測定した。飼育試験終了時に試験群ごとに5羽をと殺し,と体分析を行った。得られた成績は統計学的処理を行った。結果としてRFWの添加はブロイラーの成長,と体性状に対して影響しなかった。RFWを1.5%添加した飼料区では飼料要求率,斃死率および枝肉歩留で良好な成績を示し,成長指標の肉骨率においても他の区より有意(P<0.05)に高い値を示した。また,総コレステロール値は他の区よりも低かった。RFW2.0%添加区のブロイラーのと体はタンパク質,脂肪,総エネルギー含量が他の区に比べて最も多かった。RFWを2.0%まで高めると飼料中のカロテノイド,トコフェロール,飽和及び不飽和脂肪酸を高めることができたが,と体のpHに影響せず,柔らかさにも影響しなかった。官能試験においてパネリストはRFW添加区の色,香りを好んだ。ブロイラー飼料へのRFWの添加は成長,と体性状,肉質に対して悪影響は及ぼさず,むしろ良好な成績を誘発する可能性が示唆された。The red fruit waste (RFW) contains antioxidant effect therefore the objectives of this experiment were to confirm the effects of RFW supplementation on growth performance, carcass characteristics and carcass quality of broiler chicken as an antioxidant. A completely randomized design with five treatments and four replicates was used. Two hundred day-old Ross broiler unsexed chicks were divided into five groups and placed in twenty pens (1m×1m×1m). The chicks were fed basal diet (contained 19% crude protein and 3200kcalME/kg) as control (T_0). T_1-T_4 were added 0.5, 1.0, 1.5 and 2.0% RFW, respectively added to T_0. Body weight and feed intake were measured on a weekly basis. At the end of feeding trial, five birds per treatment-replication were slaughtered for analysis of the contents of the carcass. The data were statistically analyzed and described. The results showed that supplementation of RFW did not affect the broiler performance and carcass characteristics. The chicks fed T_3 containing 1.5% RFW owed good tendency in the values of feed conversion, mortality and dressing carcass percentage and were significantly highest (P<0.05) in performance index and meat bone ratio. They also produced a total cholesterol lower than others. The protein, fat and gross energy contents in carcass from the chickens given T_4 containing 2.0% RFW were higher compared to other treatments. Addition of RFW up to 2.0% as an antioxidant could increase carotenoid, tocopherol, saturated and unsaturated fatty acid, but did not affect the carcass pH and decreased the tenderness. In sensory properties, panelists preferred the color and smell of carcass from all RFW treatments. In conclusion, RFW in broiler diet contributed positive effects to growth, characteristics and carcass quality, without affecting performance and carcass characteristics

APLIKASI CHEMDRAW DAN AVOGADRO UNTUK MENINGKATKAN PEMAHAMAN DAN MINAT DALAM BIDANG KIMIA

In the industrial era 4.0, it is expected that the technology-based education system can be realized specifically in chemistry. One alternative in improving understanding and interest in chemistry is by ChemDraw and Avogadro applications. This research was conducted by providing training to teachers and students of ChemDraw and Avogadro applications which before and after the field data was collected by questionnaire. Significant data shown by chemistry teachers in Lombok island are few who know ChemDraw and hardly know about Avogadro. The hardest part of learning chemistry is to imagine the structure and bond in the molecule. From this exercise programmed participants are able to draw molecules both 2D and 3D. In the end the participants can draw simple to supramolecular structures with ChemDraw and Avogadro applications. Hopefully this activity can function to increase students' interest in learning chemistry
